Tier C- (72)

Bowser Jr. (クッパJr., Koopa Jr.) is a playable character in Super Smash Bros. Ultimate. He was revealed for the game along with the rest of the veterans on June 12th, 2018. He returns with his Junior Clown Car, and the Koopalings return as alternate costumes alongside him. As in Super Smash Bros. for Nintendo 3DS, he is unlockable, instead of being available from the start. Bowser Jr. is classified as Fighter #58.

As in Super Smash Bros. 4, Caety Sagoian's portrayals of Bowser Jr. from various Mario spin-off games, along with Lani Minella's portrayals of Larry, Morton, Wendy, and Lemmy, Mike Vaughn’s portrayals of Iggy and Ludwig, and Dan Falcone's portrayal of Roy from the New Super Mario Bros. games, were repurposed for Ultimate, in place of the Koopalings' respective voice actors (except Roy) from Mario Kart 8 onward.

Bowser Jr. is ranked 72nd out of 82 on the current tier list, placing him in the C- tier. This is a marginal improvement over his 47th out of 54 placement in SSB4.

How to unlock[edit]

Complete one of the following:

  • Play VS. matches, with Bowser Jr. being the 61st character to be unlocked.
  • Clear Classic Mode with Fox or any character in his unlock tree, being the 6th character unlocked after Daisy.
  • Have Bowser Jr. join the player's party in World of Light.

With the exception of the third method, Bowser Jr. must then be defeated on Delfino Plaza. In World of Light, he is fought on the Ω form of Mushroomy Kingdom.


Bowser Jr. is a unique heavyweight fighter because his Junior Clown Car has a separate hurtbox from him, making his survivability variable. Bowser Jr. sports the 20th slowest walking speed (tied with Peach and Daisy), the 21st slowest dashing speed, the 26th fastest air speed (tied with Ike and R.O.B.), the 30th fastest falling speed (tied with Ike, Corrin, Sonic, Ganondorf, and Duck Hunt), slightly above average gravity and air acceleration, and low traction. All in all, these stats render his mobility somewhat poor except in the air, and as a result, many characters supersede him in terms of approach.

Bowser Jr. and his Junior Clown Car both have separate hurtboxes, much like Duck Hunt. He possesses a unique mechanic where the Clown Car takes less damage from all incoming attacks, whereas he himself takes more damage in comparison. Unlike in SSB4, the Clown Car's hurtbox takes priority over Bowser Jr.'s hurtbox: when combined with his heavy weight, this gives him above average survivability compared to a good majority of the rest of the cast, or possibly even a good majority of other characters that are of his weight class. Bowser Jr. also possesses a purely disjointed moveset and two good projectiles in Clown Cannon and Mechakoopa.

Clown Cannon can have two cannonballs in play at the same time, deals good damage and knockback, and its cannonballs travel quickly. This makes Clown Cannon good for disrupting or throwing off approaches, as well as KOing at high percentages. This is further compounded by its outstanding shield damage, making Clown Cannon a viable punishing tool. Mechakoopa is also disruptive due to its explosion effect upon being hit. The Mechakoopa always follows opponents no matter the circumstances, and explodes upon contact, serving as an excellent KO setup against launched opponents.

Clown Kart Dash travels extremely quickly, vastly making up for Bowser Jr.'s poor approach and allowing him to easily cover long distances, both on the ground and in the air. Clown Kart Dash also deals above-average damage and knockback at maximum speed, enabling it to KO opponents at mid-high percentages. Junior can also double jump out of it, granting him potential aerial follow-ups. Abandon Ship! travels good vertical distance, allowing Junior to return to the stage if he is right below it. The Junior Clown Car itself damages opponents upon exploding, serving as a potential KO option at later percentages. While outside of the clown car, Bowser Jr. is gifted with a hammer, which deals high damage, high knockback, and has quick startup, making it a good KO option in its own right. Clown Kart Dash and Abandon Ship! can be mixed up with an air dodge, combining to give Junior an impressive recovery.

Bowser Jr.'s aerials have great utility, going hand-in-hand with his specials. Neutral aerial has edgeguarding capabilities and is effective out-of-shield because of its lingering hitbox. His forward and back aerials are great for edgeguarding, spacing, and KOing because of their high knockback, high potential damage, and good range. Bowser Jr.'s up aerial is good for juggling because of its decent speed and vertical range and serves as an additional KO option. Lastly, down aerial can shield poke, and works well with Clown Kart Dash when initiating follow-ups.

Bowser Jr.'s smash attacks are go-to KO options, all dealing high knockback and overall damage: forward smash has low ending lag, pokes shields, and can be angled; up smash has very quick startup and ending lag, pressures shields, and denies any aerial approaches; and lastly, down smash has high range and KOs, the earliest out of Junior's smash attacks.

Despite his great aerial mobility and damage-racking potential, Bowser Jr. is not without his flaws. One of his biggest problems is that his recovery is glaringly susceptible to gimps. While Abandon Ship! grants him considerable vertical distance, any weak hit can result in Bowser Jr. not being able to respawn his Clown Car if the player does not button mash. Another major problem that Bowser Jr. faces is a lack of viable options on shield, making him susceptible to punishes. Bowser Jr. is also a very straightforward character, which can make him quite predictable at times. For instance, Clown Cannon and Mechakoopa are important to Bowser Jr.'s neutral game, making it easy (especially for characters such as Fox) to read and shut down his options. Despite his grab range being rather long, his grabs have noticeable start-up and ending lag, and his throws have low utility due to their inability to KO at reasonable percentages, with only up throw possessing some combo potential. In addition, despite his high power, Bowser Jr. suffers from poor KO potential due to having very few reliable KOing options (his neutral attack finisher, smash attacks and his forward/back aerials), which is further compounded by said options being burdened with considerable ending lag. Many of his attacks, such as his tilts, also have poor range, so he fares surprisingly poorly against swordfighters considering his disjointed moveset. Finally, Bowser Jr. takes more damage if he is hit instead of his Koopa Clown Car, so he is very vulnerable to aerial approaches. Since he always takes priority over his Clown Car when thrown, Bowser Jr. is also particularly vulnerable to being grabbed and can be knocked out earlier than a character of his weight class would by strong kill throws.

Overall, Bowser Jr. fares well with a bait-and-punish playstyle like his father does, but he can also be potent at pressuring the opponent thanks to Clown Cannon, Clown Kart Dash, and Mechakoopa. However, his slew of exploitable weaknesses can make him a bit underwhelming overall, and frequently overshadowed compared to the rest of the cast. Because of this, his results and representation have been below-average overall, like in SSB4.

Changes from Super Smash Bros. 4[edit]

Near the end of Smash 4's metagame, Bowser Jr. had been considered a low-tier character (47th out of 54 characters), due to his linear playstyle, poor disadvantage state that included a very gimpable recovery despite its long distance, and his susceptibility to being racked damage on easier than most other characters due to the Clown Car mechanic. Likely as a result of this, Bowser Jr. was noticeably buffed in his transition to Ultimate.

One of the biggest changes include the Junior Clown Car now taking priority over Bowser Jr.'s hurtbox, which allows him to more reliably tank damage on average more compared to any other fighter, and making his survivability comparable to heavyweights like Donkey Kong. The other most notable buffs come from Bowser Jr's special moves, which were previously notorious for their lag and/or situational use. Clown Cannon, a previously slow projectile with limited use, is now less punishable due to its decrease in lag and increase in lifetime if fired in the air, and two can be in play at once. It also deals far more shield damage; an uncharged landing cannonball can now hit twice to almost break a full shield. Clown Kart Dash travels faster, allows Bowser Jr. to keep his double jump if cancelled, no longer requires travel time to deal maximum damage and immediately deals higher damage if the directional key is held forward, while its spinout deals far more knockback, making the move harder-hitting in general and more versatile. Abandon Ship!'s hammer swing has more range and a longer duration. Finally, Mechakoopas start moving quicker and bite onto victims, guaranteeing that the second hit will connect.

Aside from the buffs given to his survivability and special moveset, Bowser Jr. has also received several quality of life changes. Many of his moves either connect better (such as his jab and dash attack, the latter being especially relevant as the final hit has good KO potential) or have had their misleading hitboxes adjusted or their blindspots removed (such as up tilt and grab, the latter being given more range). Up throw has less endlag and knockback that renders it now capable of starting combos, while his down throw now deals much more damage, improving his previously lackluster grab game. Finally, Bowser Jr. benefits from some of the changes to universal game mechanics: the universal frame 3 jumpsquat allows Bowser Jr. to use his formidable aerials more effectively, and the increase in mobility contributes to both a better grounded approach for Bowser Jr. and improves his air game and recovery. The reintroduction of directional air dodges slightly improves his recovery, allowing him to mix up his long distanced recovery with more ease. The lower landing lag on his aerial attacks also improves their combo and spacing potential.

However, Bowser Jr. has received some noticeable nerfs. His neutral attack deals much less damage, especially in the infinite part, his forward tilt initially lost its KO potential until patch 9.0.0 where it was given a substantial increase in knockback, and neutral aerial has a sourspot that, while removing the blindspots, has more priority than the sweetspot and makes the attack less consistent. Some of his moves, such as forward smash and down aerial have altered hitbox placements that worsen their consistency, the cannonballs of Clown Cannon can only KO if fully charged, and he cannot air dodge out of Clown Kart Dash anymore. Additionally, Mechakoopas fall over if they walk into a shield, no longer penetrating them and can then be picked up by the opponent, making them much easier to deactivate and the opponent can use them against Bowser Jr. more easily because of this, thus forcing him to be more cautious of his tools. Also, the alteration of priority in his hurtboxes cause Bowser Jr. to take more damage if he is hit instead of his Clown Car, making him more vulnerable to aerial approaches and making his recovery even more vulnerable to gimps after using Abandon Ship!. A few of the universal changes hurt him overall, as his grabs have overall less range (other than his standing grab) and are slower in terms of ending lag. The changes to air dodge mechanics make him easier to edgeguard. The weakening of rage also slightly hinders his KO power, which lessens the reward and doesn't allow him to take advantage of it as easily due to his lower susceptibility to KOs compared to Smash 4. Bowser Jr. also retains several of his weaknesses from the previous game, including his poor disadvantage state, vulnerable recovery, poor range despite disjointed attacks and a somewhat linear playstyle.

In the end, Bowser Jr's moveset, while not significantly changed in terms of functionality, has been heavily adjusted to be more consistent, granting many of his moves less situational use than in Smash 4, whereas the more notable changes to his special moveset and his faster mobility allow him to zone opponents more effectively and approach with less risk. He has also received a few notable changes in game updates, further contributing to his notable buffs. Although many top-level players claim Bowser Jr. has not significantly improved from Smash 4 due to retaining many of his weaknesses from the previous game and several veteran characters also being buffed to varying degrees, this is contentious due to having a few notable performances in competitive play, thanks to players such as Young Eevey and Ketchup. As such, Bowser Jr's true viability remains debatable.


  • Change Due to the aesthetic used in Ultimate, Bowser Jr.'s model features a more subdued color scheme. His horns, hair, spikes, bands, and bandana feature greater detailing, but his scales remain undefined and his body is not as monotone. The new detailing is also expressed by the Koopalings.
  • Change The Junior Clown Car also features a more subdued color scheme. Its "facial" proportions have been adjusted, and it has a more polished finish. Additionally, the inside of the Junior Clown Car now contains a visible control panel.
  • Change Morton's star mark is now gray instead of dark brown, matching his appearance in Mario Kart 8 onwards.
  • Change Instead of a hammer, the Koopalings pull out their respective wands from Super Mario Bros. 3 and the New Super Mario Bros. games.
  • Change Bowser Jr. is more expressive, he has a shocked expression when hit and a scared expression when grabbed. The Junior Clown Car is also expressive, with new facial animations when Bowser Jr. gets hit and when he misses a grab.
    • Change The Koopalings are more emotive than before, with their eyes and mouths animating somewhat differently from Bowser Jr.'s. Previously, only Lemmy had unique expressions.
  • Change Larry, Morton, Lemmy, and Ludwig's hair respectively have less independent physics. On the contrary, Wendy's bow and rings have greater independent physics.
  • Change Air dodge, falling, and ledge-hanging animations have changed.
  • Bug fix The Junior Clown Car's propeller now properly rotates during Bowser Jr.'s No Contest screen.
  • Change The PAL English version of Palutena's Guidance now uses the term "Koopalings" instead of "Bowser's minions", matching the British English localization in their home series as of Mario & Luigi: Paper Jam.


  • Buff Like all characters, Bowser Jr.'s jumpsquat animation takes three frames to complete (down from 6).
  • Buff Bowser Jr. runs faster (1.424 → 1.566).
  • Buff Bowser Jr.'s initial dash is faster (1.6 → 1.76).
  • Buff Bowser Jr. walks faster (0.88 → 0.924).
  • Buff Bowser Jr.'s air speed is faster (1.08 → 1.134)
  • Buff Forward roll has less ending lag (FAF: 31 → 30).
  • Nerf Forward roll grants less intangibility (frames 4-17 → 4-15).
  • Nerf Back roll has slower startup (frame 4 → 5), grants less intangibility (frames 4-17 → 5-16) and has more ending lag (FAF: 31 → 35).
  • Buff Spot dodge has less ending lag (FAF: 28 → 25).
  • Nerf Spot dodge grants less intangibility (frames 3-18 → 3-17).
  • Buff Air dodge grants more intangibility (frames 3-28 → 3-30).
  • Nerf Air dodge has significantly more ending lag (FAF: 34 → 50).
  • Change The changes to air dodge mechanics both help and hinder Bowser Jr.: he can make use of a directional air dodge to lengthen and mix up his recovery without the need to use Abandon Ship!, but the single air dodge limit makes him more vulnerable to edgeguarding.
  • Buff Bowser Jr.'s Junior Clown Car hurtbox takes priority over his body hurtbox, meaning that if the opponent hits the Clown Car and body hurtboxes at the same time, he takes less damage.

Ground attacks[edit]

  • Neutral attack:
    • Buff The first hit has two additional hitboxes, one of which sends towards Bowser Jr. (angle: 180°).
    • Buff The second hit has an additional hitbox, and all of its hitboxes keep opponents on the ground (80°/70 → 361° (all)). This allows it to lock.
    • Buff The second hit has less ending lag (FAF 40 → 30) and has gained a hitstun modifier of 3, allowing it to connect into the neutral infinite much more reliably.
    • Buff The first and second hits have less knockback (hit 1: 10 base/50 scaling → 25/25/20/20 / 25/25/15/15, hit 2: 24 base/50 scaling → 25/25/20 / 25/25/15). This allows them to connect better and jab lock for longer.
    • Nerf The first and second hits' hitboxes are smaller (hit 1: 3u/4u → 2u/2u/2.2u/2.2u, hit 2: 3.2u/4u → 2.5u/3.2u/3.8u), reducing their vertical range.
    • Change The first and second hits have increased hitlag (hit 1: 1x → 1.5x, hit 2: 1x → 1.2x).
    • Nerf The first hit and infinite deal less damage (hit 1: 3% → 2%, infinite: 2% → 0.5%).
    • Buff The infinite has faster startup (frame 10 → 4), a faster rehit rate (4 → 2), less knockback (20 base/20 scaling → 8/10), reduced hitlag (1x → 0.5x) and SDI (0.8x → 0.5x) multipliers, keep opponents on the ground (74° → 361°), and have a new extended hitbox in front of the Clown Car (size: 5u, Y/Z-offset: 6.5, Z-offset: 21-13). Overall, these changes make it much harder to escape, and compensate for the move's lower damage.
    • Buff The infinite's finisher has a new animation: it is an uppercut instead of a jab. It has slightly faster startup (frame 8 → 7) and has three hitboxes instead of one, which have bigger size (5u → 5.5u) and are positioned differently throughout the move (Y-offset: 6 → 6.5, Z-offset: 13 → 13/18/22.5). This gives it much more range, making it a significantly more consistent KO option.
    • Nerf The finisher has more ending lag (FAF 39 → 44).
    • Change The infinite has gained a shieldstun multiplier of 8×. This allows it to lock opponents into their shields between each hit, and thus pressure them more effectively, but also allows them to cancel shieldstun and punish Bowser Jr. more easily if they shield 10 hits or more.
  • Forward tilt:
    • Buff Forward tilt has less ending lag (FAF 34 → 32).
    • Nerf It has a sourspot that deals less damage (8% → 6%).
    • Nerf It deals altered knockback (30 base/110 scaling → 72/70). While this makes it even safer on hit at low percentages, it also worsens its previously respectable KO power.
  • Up tilt:
    • Buff Up tilt's hitboxes' positions have been adjusted (ID 0: 4-3 X-offset/4 Z-stretch → 8.5-10/0, ID 1: -1-0 X-offset → 0-3.5). This removes the blindspot between the fork's prongs and the Clown Car.
    • Buff It has less ending lag (FAF 33 → 31).
  • Down tilt:
    • Buff Down tilt deals more damage (hits 1-2: 1.5% → 2%, hit 3: 5% → 6%, total: 8% → 10%), with no compensation on the third hit's knockback, slightly improving its KO and edgeguarding potential.
    • Buff The first two hits have reduced hitlag (1x → 0.5x), and have gained a hitstun modifier of 4 with a shieldstun multiplier of 1.2x.
    • Nerf The first two hits no longer deal set knockback (30 set/100 scaling → 20 base/30 scaling), and thus connect worse at higher percents.
  • Dash attack:
    • Buff The looping hits deal more damage (1.5% → 1.8%, total: 11.5% → 13%).
    • Buff It has slightly less ending lag (FAF 50 → 48).
    • Nerf One of the looping hits' hitboxes is smaller (ID 1: 5u → 4u).
    • Buff The looping hits have received several adjustments that allow the move to connect much more reliably:
      • Buff One of the hitboxes is larger (ID 0: 2.8u → 4u).
      • Buff One of the hitboxes is no longer located in the buzzsaw, being separate from Bowser Jr. (ID 1: bone 1041 → 0, 0 Y-offset/0 Z-offset/stretch → 8/13-8). While this results in around the same range, this means the hitbox no longer moves around the Z-axis.
      • Change One of the hitboxes is positioned differently (ID 0: 9 Y-offset/8-13 Z-offset → 8/9-8). This is made up by the other hitbox's new position.
      • Buff The two previous hitboxes send at different angles (25° (all) → 30°/34°).
      • Buff There is a new hitbox (ID 2, angle: 65°, size: 4u, 8 Y-offset/18-8 Z-offset), which temporarily gives the attack more range.
      • Buff There is a "late" hit on frames 13-20, comprised of two hitboxes which have the same size as the new ones, but are positioned differently (ID 1: 8 Y-offset/9-8 Z-offset, ID 2: 8 Y-offset/14-8 Z-offset) and send at different angles (25° (all) → 32°/65°).
      • Buff All hits have reduced hitlag (1x → 0.6x), making the move less prone to SDI.
    • Buff The final hit launches at a more horizontal angle that is more desirable for edgeguarding (60° → 50°).
    • Change The final hit has increased hitlag (1.5x → 1x). This makes it safer on shield, but easier to DI.
  • Forward smash:
    • Buff The looping hits' closest hitbox to Bowser Jr. is larger (ID 1: 1u → 2.5u), which allows the attack to connect better up close.
    • Nerf The looping hits' hitboxes are positioned differently and don't extend as much (ID 0: 7-13 Y-offset/18 Z-offset → 8-12.5/16.5 (non-angled), 10-16 Y-offset/18-17 Z-offset → 12-16.5/15-14.5 (angled up), 4-10 Y-offset/17-18 Z-offset → 3.5-7.5/16-17; ID 1: 5-11 Y-offset/12.2 Z-offset → 7-12/9.7 (non-angled), 8-14 Z-offset/12.2-11.2 Z-offset → 10-15/8.3-7.8 (angled up), 2-8 Y-offset/11.2-12.2 Z-offset → 4.5-9/9.1-10.5 (angled down)), while the farthest hitbox to Bowser Jr. is smaller (ID 0: 5u → 4.5u). This reduces the looping hits' range.
      • Buff However, this somewhat fixes the blindspot in front of Bowser Jr., making the looping hits connect slightly more reliably.
    • Buff The final hit has slightly faster startup (frame 36 → 35) making it connect more reliably from the looping hits.
    • Nerf The final hit's hitbox is smaller (7u → 6u) and does not extend as far (non-angled: 8-12 Y-offset/18 Z-offset → 9-12/17; angled up: 11-15 Y-offset/18-17 Z-offset → 13-16/16-15; angled down: 5-9 Y-offset/19-18 Z-offset → 4.5-6.5/16.5-17). This noticeably reduces its range and, combined with the changes to the looping hits above, causes opponents to potentially fall out more frequently.
  • Up smash:
    • Change The move's hitboxes have shorter durations (hit 1: frames 7-9 → 7-8, looping hits: frames 10-24 → 9-18, second to last hit: frame 25 → 18, last hit: 30-31 → 22-23), and the looping hits have a faster rehit rate (4 → 3).
      • Change As a result, the move hits six times instead of seven. However, the second to last hit has been merged with the looping hits on frame 18, leaving the move's total damage unchanged (1.3% hits 2-5/1% hit 6 → 1.3% hits 2-4/2.3% hit 5).
    • Change The move has a green visual trail that matches the Junior Clown Car's propeller. Strangely, the color does not change for the Koopalings.
    • Buff The faster gap between hits allows the move to connect more reliably.
      • Nerf However, this gives the move more ending lag as a result, despite its faster interruptibility (FAF 57 → 54).
    • Buff It has larger hitboxes (2.5u/2.5u/4u → 3.2u/3.2u/4.7u (clean loop), 4.6u → 5.1u (late loop), 5.5u → 6.5u (last hit)) that stretch farther horizontally (Z offset: -4u—7u → -6.5u—7u (loop), -4u—5u → -5u—5u (last hit)), with the last hit placed lower (Y offset: 24.5u—22.5u → 23u—21u). The looping hits also launch at different angles (120°/190°/140° → 105°/175°/140°), and their hitbox with the lowest priority deals more knockback (base: 0 → 30). Altogether, these changes allow the move to connect more reliably.
    • Change The looping hits are positioned higher up from Bowser Jr. (17-15 ID 0/20-18 ID 1/17-15 ID 2 (Y-offset) → 18-16/21-19/18-16). This improves their upwards range and allows them to connect slightly more reliably, but makes it slightly harder to hit smaller/crouching targets on the ground.
    • Buff Except for the second to last hit, the looping hits have reduced hitlag (1x → 0.6x). Combined with the move's improved upwards range and faster gap between hits, this makes the move harder to escape.
    • Buff The final hit deals more base knockback (32 → 38).
    • Nerf The final hit has a smaller hitbox (6u → 5.5u), reducing its vertical range, although its horizontal range was mostly compensated (23-21 Y-offset → 24.5-22.5).
  • Down smash:
    • Buff Down smash has less startup (frame 15 → 12), with its total duration reduced as well (FAF 60 → 57).
    • Buff Its hitboxes have a slightly longer duration (frames 15-16 → 12-14).
    • Buff It deals slightly more knockback (40 base/89 scaling → 41/91).

Aerial attacks[edit]

  • Buff All aerials have less landing lag (neutral: 18 frames → 9, forward: 27 → 16, back: 24 → 14, up: 15 → 9, down: 25 → 15).
  • Neutral aerial:
    • Buff Neutral aerial deals more damage (6% clean/5% mid/3% late → 8%/7%/5%), with knockback scaling mostly compensated (100 → 83/81/80).
    • Buff It has hitboxes on the Clown Car's arms (size: 4u clean/3.5u mid/3.0u late, X-offset: -3), which removes the blindspots in front of Bowser Jr. They deal less damage than the sweetspots, but more than the move's previous damage (6.5% clean/5.5% mid/3.5% late).
      • Nerf However, the new sourspots outprioritize the sweetspots. Since their knockback was not compensated, this makes the move weaker if the sourspots connect.
  • Back aerial:
    • Buff Back aerial's sourspot extends into the Clown Car (X-offset: 0 → 0—-6), removing its blindspot.
  • Down aerial:
    • Buff The looping hits have a faster rehit rate (4 → 3), making the move hit up to nine times instead of seven.
    • Buff The looping hits have reduced hitlag (1x → 0.8x).
    • Buff It deals more damage (1.3% looping hits/2% last hit → 1.5%/2.5%). Combined with the move's faster rehit rate, this makes the move deal more damage if all hits connect (9.8% → 14.5%), though with the last hit's knockback scaling compensated (130 → 124).
    • Buff One of the looping hits' hitboxes is extended and positioned further up (Y-offset: 2 → 4, Z-offset/stretch: 0 → -2—2), giving it more range.
      • Change However, since the last hit is not extended, this can cause it to fail to connect into the last hit.
    • Nerf One of the looping hits' hitboxes (ID 2) has been removed, while the old one (ID 1) detects both aerial and grounded opponents. However, the hitbox no longer sends at an autolink angle (366° → 96°). Combined with the above change, this causes the looping hits to connect less reliably, despite their reduced hitlag and faster rehit rate.
    • Change The looping hits have altered knockback (30 set/100 scaling (ID 0), 30 base/100 scaling (ID 1) → 30 base/10 scaling (both)). This allows them to connect more consistently at low percentages, but since all of its hitboxes no longer use set knockback, it still connects less consistently at very high percentages.
    • Buff The landing hitbox extends further (Z-offset: -2—2 → -2.5—2.5), improving its range.
      • Change The hitbox has also been moved upwards (Y-offset: 3.2 → 4).

Throws and other attacks[edit]

  • Grabs:
    • Change Bowser Jr. preemptively pulls out his toy hammer in his grab animation and holds it while the opponent is grabbed.
    • Change The color of the claw matches each Koopaling's Clown Car.
    • Buff Standing grab has faster startup (frame 12 → 11).
    • Nerf Dash and pivot grabs have slightly more startup lag (dash/pivot: frame 13/12 → 14/15).
    • Nerf All grabs have more ending lag (Standing/dash/pivot: FAF 36/45/42 → 41/49/44).
    • Buff Standing grab's grabbox has been moved forwards (Z-offset: 4-13 → 6.5-14), improving its notoriously poor range despite being less extended.
    • Nerf Dash and pivot grab's grabboxes are less extended, especially pivot grab (dash: 4-15.5 Z-offset → 6.5-15, pivot: 4—-21.5 Z-offset → 6.5—-16.4), reducing their range.
  • Pummel:
    • Change Pummel's animation is slightly different.
    • Nerf It deals less damage (2% → 1.3%).
    • Buff It has faster startup (frame 6 → 1), deals more hitlag (4 frames → 14) and has less ending lag (FAF 18 → 6), shortening its duration and increasing the number of times Bowser Jr. can pummel the opponent before throwing them or before they break out.
  • Change Forward, back and up throws are no longer weight dependent.
  • Forward throw:
    • Buff Forward throw has less ending lag (FAF 36 → 35).
    • Buff The throw deals more damage (6% (throw)/9% (total) → 7%/10%) and has more knockback scaling (70 → 92), significantly improving its KO potential.
  • Back throw:
    • Nerf Back throw deals less damage (12% → 11%) without full compensation on its knockback scaling (65 → 70), slightly hindering its KO potential.
  • Up throw:
    • Buff Up throw has less ending lag (FAF 45 → 38) and deals less knockback (55 base/85 scaling → 65/60), granting it combo potential.
  • Down throw:
    • Buff Down throw has seven looping hits instead of five that deal significantly more damage (0.5% (hits 1-5)/6.5% (total) → 1.2%/12.4%).
    • Buff It sends at a more horizontal angle (55° → 30°), allowing it to set up edgeguards.
    • Change It deals less knockback overall (80 base/110 scaling → 90/55).
    • Nerf It has more ending lag (FAF 75 → 78).
  • Edge attack:
    • Buff Edge attack deals more damage (7% → 10%).

Special moves[edit]

  • Clown Cannon:
    • Buff Clown Cannon has faster startup (frame 43-103 → 37-97) and less ending lag (FAF 81-141 → 73-133).
    • Buff Bowser Jr. can have up to two cannonballs in play at once.
    • Buff A cannonball's hitbox is bigger (3.2u → 3.8u).
    • Buff A cannonball travels in a spiraling path (similar to King K. Rool's Blunderbuss and ones fired by Shotzos in Super Smash Bros. for Nintendo 3DS's Smash Run), instead of flying straight. Combined with the above change, this noticeably increases a cannonball's effective range.
    • Buff A cannonball keeps an active hitbox after it starts to fall in midair, allowing the move to be used for edgeguarding. However, this does not apply for cannonballs that have already landed, and cannonballs can only hit non-shielding opponents once.
    • Buff An uncharged cannonball deals more damage (8.5% early/5.9% late → 10%/7%).
    • Buff A cannonball deals shield damage (0 → 8), capable of doing more than half a shield's health when fully charged.
    • Change The cannonball travels slower (Speed: 1.3 (min)/2.9 (max) → 1/2.4), letting Bowser Jr. follow it. This makes cannonballs easier to dodge, but grants new setups based around them.
      • Buff Combined with the above change, an uncharged cannonball can hit shields twice before it drops at maximum distance, dealing extreme shield damage.
    • Nerf A cannonball deals significantly altered knockback (40 base/82 scaling → 90/52). This makes them safe on hit at any percentage, but significantly worsen their KO power, only having KO power if one is fully charged.
  • Clown Kart Dash:
    • Buff The Clown Car moves faster and reaches its maximum speed immediately after beginning to move, therefore no longer needing to accelerate to deal maximum damage with the collision.
    • Buff Its armor resists more damage (9% → ~10.2%).
    • Buff The collision deals more damage (4%-7% → 5.2%-8.8%).
    • Change The collision has more knockback scaling (80 → 95). This improves its combo ability from low-mid to mid percentages, but reduces it at high ones.
    • Buff The spinout deals more damage (8%-12% → 10%-16.3%) with knockback scaling not fully compensated (80 → 75), noticeably improving its KO power.
    • Buff The spinout has faster startup (frame 5 → 3).
    • Buff If the move is canceled it in the air, Bowser Jr. keeps his double jump. This significantly improves Bowser Jr's recovery, giving it more mix-ups.
    • Nerf It can no longer be air dodged out of.
    • Change It makes Bowser Jr. jump higher on sloped platforms.
  • Abandon Ship!:
    • Change The Clown Car no longer respawns when Bowser Jr. grabs onto a ledge after using Abandon Ship!. While this results in him always receiving 1.15x damage if he gets hit, it also means that his hurtbox is considerably smaller.
    • Buff The initial launch and explosion have less startup (frame 21/60 → 17/56), which also allows Bowser Jr. to swing his hammer 4 frames earlier.
    • Buff The hammer swing has a longer hitbox duration (frame 8/13 → 8-9/13-14), and the hitboxes are even larger (6.5u/3.0u → 7.0u/3.5u).
    • Nerf Like with regular air dodges, Bowser Jr. can only use a single air dodge out of Abandon Ship!. This makes him easier to edgeguard.
  • Mechakoopa:
    • Buff Mechakoopas start walking earlier (frame 54 → 48), and no longer bounce.
    • Buff They cling onto the opponent they make contact with, detonating on them even if they are being knocked away. This makes them connect into the second hit reliably, and allows for more reliable kill setups.
    • Change They explode upon hitting a shield if thrown.
    • Nerf They deactivate and lie on the ground when they walk into a shield, no longer crossing them up. They can still be picked up and used before they completely disappear after a second passes. This makes them easier to use against Bowser Jr.
  • Shadow Mario Paint:
    • Nerf Shadow Mario Paint is active for a shorter amount of time.

Update history[edit]

Bowser Jr. has been buffed by game updates. Update 3.1.0 granted Bowser Jr. several useful buffs. Up tilt and aerial Clown Cannon had their lag decreased by varying amounts, which improved their combo potential and safety, respectively. Dash attack's edge-guarding potential was improved, thanks to its last hit's angle being lowered noticeably. Up smash's KO potential was improved slightly, thanks to a small knockback increase.

Clown Kart Dash's travel speed was increased (which also heightened its damage output by extension) and its hitbox now remains active upon its bounce, the latter of which improved its consistency. Lastly, Abandon Ship! became slightly more consistent: its grounded Junior Clown Car hitbox connects better with its explosion hitbox, while its hammer's duration and hitboxes were lengthened and enlarged, respectively.

After update 7.0.0 enlarged Bowser Jr.'s shield as part of a near-universal buff, update 9.0.0 granted Bowser Jr. his most useful buffs to date. Forward tilt and especially forward throw gained considerable knockback increases; while the former is now better for spacing and safer on hit, the latter is now a viable (albeit situational) KO option, which is something Bowser Jr.'s grab game lacked following back throw's nerf in the transition to Ultimate.

Up smash underwent several hitbox, knockback and angle adjustments in order to improve its consistency, while down smash's overall lag was decreased. Clown Kart Dash became safer thanks to its armor threshold being noticeably increased. Lastly, Abandon Ship!'s recovery potential was improved, thanks to its start-up lag being decreased.

In update 13.0.1 Bowser Jr received some more buffs and a nerf. Clown Kart Dash was given more base knockback on its spin, dash attacks damage was increased and its first and last hits had their base knockback decreased. Down tilt’s first and second hit were given less knockback growth and less base knockback, and its final hit had its launch angle adjusted to launch at a lower angle. However, Bowser Jr’s down tilt also received a nerf, only the first hit of his down tilt will hit opponents that are hanging on the ledge preventing the full move from connecting properly.

As a result of these changes, Bowser Jr. fares better than he did at Ultimate's launch.

Super Smash Bros. Ultimate 1.1.0

  • Buff Abandon Ship! has more air dodge frames, but they start later (frames 2-25 → 3-30).
  • Nerf After using Abandon Ship!, Bowser Jr. can no longer air dodge more than once.
  • Buff Shortened the amount of time required to input another jump or air dodge after jumping out of Clown Kart Dash (40 frames → 32).
  • Nerf When using Clown Kart Dash to collide into a wall, Bowser Jr. descends instead of ascends. This removes its ability to stall an opponent.
  • Buff Bowser Jr. loses less horizontal speed after colliding into a wall with Clown Kart Dash (0.7× → 0.62×).

Super Smash Bros. Ultimate 3.0.0

  • Buff Neutral attack 2 deals more hitstun (0 → 3), allowing it to connect into the rapid jab more reliably.

Super Smash Bros. Ultimate 3.1.0

  • Buff Up tilt has less ending lag (FAF 33 → 31).
  • Buff Dash attack's last hit's angle has been adjusted (60° → 50°). This improves its edgeguarding potential.
  • Buff Up smash's last hit has more base knockback (32 → 38).
  • Buff Aerial Clown Cannon has less startup (frame 43-103 → 37-97) and ending lag (FAF 79-139 → 73-133).
  • Buff Clown Kart Dash travels faster.
    • Buff Due to its damage output being determined by Bowser Jr.'s speed, its collision also deals more damage (4%-7.3% → 5.2%-8.8%).
  • Buff Clown Kart Dash's hitbox remains active after bouncing off the ground.
  • Bug fix Fixed a glitch where Bowser Jr. could cancel aerial Clown Kart Dash's spinout into a jump within a few frames of landing on the ground.
  • Buff Grounded Abandon Ship!'s clown car hitbox connects with its explosion hitbox more reliably.
  • Buff Abandon Ship!'s hammer has larger hitboxes (6.5u/3u → 7u/3.5u) and a longer hitbox duration (frame 8 (hit 1)/13 (hit 2) → 8-9/13-14).

Super Smash Bros. Ultimate 7.0.0

  • Buff Overall shield size has been increased.

Super Smash Bros. Ultimate 9.0.0

  • Bug fix Bowser Jr. correctly falls through platforms instead of landing and crouching on them when holding down.
  • Buff Forward tilt has more base knockback (55 → 72), increasing its safety on hit at low percents.
  • Buff Up smash has larger hitboxes (2.5u/2.5u/4u → 3.2u/3.2u/4.7u (clean loop), 4.6u → 5.1u (late loop), 5.5u → 6.5u (last hit)) that stretch farther horizontally (Z offset: -4u—7u → -6.5u—7u (loop), -4u—5u → -5u—5u (last hit)), with the last hit placed lower (Y offset: 24.5u—22.5u → 23u—21u). The looping hits also launch at different angles (120°/190°/140° → 105°/175°/140°), and their hitbox with the lowest priority deals more knockback (base: 0 → 30). Altogether, these changes allow the move to connect more reliably.
  • Buff Down smash has less startup (frame 15 → 12), with its total duration reduced as well (FAF 60 → 57).
  • Buff Forward throw has much more knockback scaling (70 → 92), significantly improving its KO potential, to the point it can KO middleweights at around 150% at the edge.
  • Buff Edge attack after using Abandon Ship! deals more damage (9% → 10%), no longer dealing less than a standard edge attack.
  • Buff Clown Kart Dash's armor resists more damage (6% → ~10.2%).
  • Buff Abandon Ship! has less startup (frame 21 → 17).

Super Smash Bros. Ultimate 13.0.1

  • Buff Clown Kart Dash has more base knockback when spinning out (60 → 67).
  • Buff Dash attack's multi-hits deal more damage (1.8% → 2%), and some of the hitboxes having less base knockback (50 → 45 (early, hitbox 0), 40 → 35 (mid, hitbox 1), improving its consistency.
  • Down tilt:
    • Buff The first and second hit of down tilt has less knockback growth (30 → 11) less base knockback (20 → 17) and the final hit of down tilt launches at a lower angle (45 → 40).
    • Nerf Only the first hit of down tilt will hit opponents hanging from the ledge, whereas before the first hit would lift opponents into the rest of the attack. Additionally, airborne opponents with frame 1 intangible options (such as Rest) can now escape the final hit, as the lower knockback reduces hitstun.


  • Moves that hit the Junior Clown Car deal 0.88× damage, whereas those that hit Bowser Jr. himself will deal 1.15× damage. The Junior Clown Car's hurtbox takes priority over Bowser Jr.'s hurtbox, unlike in Smash 4, where it was the opposite.

For a gallery of Bowser Jr.'s hitboxes, see here.

Note: All numbers are listed as base damage, without the 1v1 multiplier.

  Name Damage Description
Neutral attack Clown Jab (クラウンジャブ) / Clown Hook (クラウンフック) / Clown Hundred Rending Punch (クラウン百裂パンチ) / Clown Hundred Rending Finish (クラウン百裂フィニッシュ) 2% The Junior Clown Car performs a one-two combo, followed by a flurry of punches that ends with an uppercut. The fists come from New Super Mario Bros U. It has impressive damage racking potential, as it can easily deal around 20%. Its first hit comes out on frame 4 and has excellent knockback for a jab, making it one of the few jabs that can KO. It can KO at the ledge around 100%. This makes jab a viable grounded KO and ledge trap option. It is similar to Bowser Jr.’s animation when he is at half health as a boss in Mario Party: Star Rush.
0.5% (loop), 3% (last)
Forward tilt Fork (フォーク) 8% (sweetspot), 6% (sourspot) The Junior Clown Car stabs a large dinner fork forward. It can be angled and is very useful for spacing.
Up tilt Push-Up Fork (突き上げフォーク) 6% The Junior Clown Car stabs a large dinner fork upward. It can combo into itself beginning at around 10% and juggle at medium percentages. It is also great at anti-airing due to its fast startup and large disjoint.
Down tilt Licking (なめまわし) 2% (hits 1-2), 6% (hit 3) The Junior Clown Car uses its tongue to lick forward three times. It has a fair amount of utility, as it is efficient at warding off rushdowns, can act as a set-up for a dash attack, or interfere with an opponent attempting to grab an edge due to its undulating hitbox. It can KO opponents at ledge at under 120%.
Dash attack Round Saw (丸ノコギリ) 2% (hits 1-5), 4% (hit 6) The Junior Clown Car opens its mouth to swing a grinder twice.
Forward smash Smash Twin Drills (スマッシュツインドリル) 1% (hits 1-5), 11% (hit 6) The Junior Clown Car uses two drills to drill the opponent in place. The final hit is a powerful KOing option, while the whole move has low ending lag and it can be angled. The drills come from Super Mario Galaxy 2, but they bear a resemblance to the drills from Kid Icarus Uprising.
Up smash Rotary Mixer (ロータリーミキサー) 1% (hit 1), 1.3% (hits 2-4), 2.3% (hit 5), 6% (hit 6) Bowser Jr. performs a handstand to attack with the Junior Clown Car's spinning propeller. It is Bowser Jr.'s fastest smash attack, with its multiple hits being useful for pressuring shields or denying aerial approaches.
Down smash Double Iron Ball (ダブル鉄球) 18% The Junior Clown Car slams two wrecking balls on both sides. It is Bowser Jr.'s most powerful smash attack, and is the third strongest down smash in the game, making it deadly for punishment. However, it has high ending lag unlike his other smash attacks, making it equally as punishable.
Neutral aerial Propeller Punch (プロペラパンチ) 8% (clean), 7% (mid), 5% (late) The Junior Clown Car twirls around with the boxing glove arms extended. It is a weak but useful aerial, which combos reliably from Clown Kart Dash and is effective as a anti-pressure and edgeguarding option.
Forward aerial Iron Ball Swing (鉄球ふりまわし 11%/9% (clean), 8%/6.5% (mid), 5%/4% (late), 2% (landing) The Junior Clown Car swings a wrecking ball forward in a circling motion. Landing while the wrecking ball is still out produces another hitbox, which can lead to more follow-ups on the ground, as well as compensate for its high landing lag. Useful for edge-guarding and spacing, as well as a viable KOing option.
Back aerial Back Iron Ball (裏鉄球) 14% (clean tip), 8% (clean base, late) The Junior Clown Car thrusts a wrecking ball backward. Useful for edge-guarding and a viable KOing option due to its high knockback.
Up aerial Ceiling Crush (天井砕き) 10% (clean), 6.5% (late) Quickly swings a hammer above himself; if playing as the Koopalings, they instead swing their respective wands. Bowser Jr. is often able to link two or three additional up-airs, making for an excellent damage-racking and combo move. Has KO potential at around 170%.
Down aerial Piercing Drill (突き刺しドリル) 1.5% (hits 1-8), 2.5% (last), 2% (landing) The Junior Clown Car extends a drill from its underside hatch to pierce opponents. Its high ending lag is compensated by the hitbox it produces upon landing, which grants it follow-up potential. If the attack hits an opponent, it can cancel quickly into other moves; if not, Bowser Jr. suffers from moderate ending lag. Unlike most down aerials, Bowser Jr.'s is unable to meteor smash.
Grab Grab (つかみ) The Junior Clown Car extends a claw to grab the opponent. A slow grab overall.
Pummel Grab Piko Piko Hammer (つかみピコピコハンマー) 1.3% Hits the opponent with a toy hammer. A fairly fast pummel. The toy hammer looks identical to the one used in the Eekhammer sticker from Paper Mario: Sticker Star. Each hit plays the recurring sound of Mario jumping onto a Koopa Troopa shell in the Super Mario franchise.
Forward throw Body Blow (ボディブロー) 3% (hit 1), 7% (throw) The Junior Clown Car throws an uppercut. It is fairly good for launching opponents at the edge for an edge-guard. It is also Bowser Jr.'s strongest throw, as it can KO most middleweights starting around 150% without rage.
Back throw Centrifugal Throw (遠心投げ) 11% The Junior Clown Car twirls and then throws the opponent backward. Bowser Jr.'s second strongest throw, as it can KO most middleweights starting around 160% without rage.
Up throw Fling Away (放り投げ) 7% The Junior Clown Car flings the opponent upward. It can lead into up aerial at low percentages.
Down throw Back Drill (バックドリル) 1.2% (hits 1-7), 4% (throw) The Junior Clown Car throws the opponent onto the ground and then extends a drill from its underside hatch to pierce opponents. It deals good damage (~12% before 1v1 multipliers) and can set up into tech chases at medium percentages into Clown Kart Dash.
Floor attack (front)   6% Gets up while spinning a pair boxing gloves outstretched on both sides.
Floor attack (back)   7% Gets up while spinning a Grinder around himself.
Floor attack (trip)   5% Gets up while thrusting a large dinner fork to both sides.
Edge attack   10% Slams a pair of wrecking balls while climbing up.
Neutral special Clown Cannon 10% (uncharged), 7% (uncharged late), 20% (fully charged), 14% (fully charged late) The Junior Clown Car opens its mouth and fires a cannonball. It can be charged to increase the cannonball's speed and power. At the end of its path, the cannonball will drop to the ground, which can hit opponents attempting to recover if it is spaced properly. However, it has high overall lag. As the projectile's hitbox changes once it begins to drop to the ground, a cannonball can hit an opponent's shield twice with correct timing, which deals immense shield damage.
Side special Clown Kart Dash 5.2%-8.8% (collision), 10%-16.3% (doughnut) The Junior Clown Car transforms into a go-kart that speeds forward. Gains 9% damage-based armor on only the Junior Clown Car, effectively granting 10.2272% damage-based armor due to its 0.88× damage multiplier. Tilting the control stick/circle pad in the opposite direction or pressing the attack/special button will cause the Junior Clown Car to perform a doughnut, which deals significantly more damage and higher knockback to opponents on contact compared to simply charging into them. Spinning out in the air can produce horizontal movement, after which it can be used again. All versions of the move can be jump canceled, even right after hitting an opponent, which can lead into combos and mix-ups.
Up special Abandon Ship! 5% (contact), 13% (explosion), 15%/10% (hammer) Bowser Jr. ejects himself from the Junior Clown Car. The Junior Clown Car slowly falls to the ground and then explodes with high power when the move is used in midair, whereas it will simply explode after a brief period when used on the ground. When Bowser Jr. is out of the Junior Clown Car, he is not rendered helpless and can still attack with a hammer (or in the case of the Koopalings, their respective wands), which is powerful enough to KO at medium to high percentages. He is also able to airdodge once. However, taking any weak hit while out of the Junior Clown Car prevents another use of the move without button mashing or landing. The Junior Clown Car's angle usually sends opponents at a favorable position to follow up with the hammer swing.
Down special Mechakoopa 2% (contact), 7% (explosion) The Junior Clown Car drops a Mechakoopa from its underside hatch. The Mechakoopa falls in a strong downward arc; once it lands, it starts walking around. If it reaches a wall or dead end, it will turn around and walk in the opposite direction. If it makes contact with an opponent (or travels enough distance in the air without landing), it will detonate. The Mechakoopa will also bite onto opponents on contact, guaranteeing that it will explode on them shortly after Lastly, if enough time passes and they have not hit an opponent yet, they will spark out and detonate automatically. They can be picked up and thrown as items either by Bowser Jr. or his opponent. If an opponent shields a walking Mechakoopa, it will drop to the ground harmlessly, which can then be picked up.
Final Smash Shadow Mario Paint 3% (paint), 5% (explosion) Bowser Jr. transforms into Shadow Mario before flying upwards, using the Magic Paintbrush to paint a giant, orange X on the screen. Anyone caught in the X's hitbox will be damaged, with the X pulling opponents into it once they are hit. The X will clear away with an explosion after some time. The sheer size of the X makes avoiding damage from this Final Smash difficult, similarly to Iceberg.

Victory poses[edit]

  • Left: Jumps out of the Clown Car, hops in celebration twice, then poses.
  • Up: From the side of the screen, drives the Clown Car in its go-kart form, performs a donut before coming to a stop and pulls out a hammer (or a wand, if playing as a Koopaling).
  • Right: Dismounts from the Clown Car using its left grabber claw and pats it with his right hand.
A music piece based on the same melody as the Mario victory theme, but instead of a standard orchestral arrangement, the piece is played with slightly distorted electric guitars. It also sounds similar to the level clear theme of Bowser's sidequests in Paper Mario: The Thousand-Year Door.

Tier placement and history[edit]

Bowser Jr. was initially thought to be one of the worst characters in the game. People immediately noticed that he retained his weaknesses from Smash 4 (poor grounded mobility, susceptible to gimps, lack of range and his playstyle being linear). Despite improvements towards his survivability, Clown Cannon (widely agreed to be one of the worst projectiles in Smash 4) and his grab game, many players claimed that the improvements were not significant enough to compensate for his retained weaknesses. As such, Bowser Jr. was considered a low-tier character at best, with some even going as far as claiming him to be a bottom 3 character.

This negative perception would change as the metagame progressed thanks to noteworthy results from players such as Young Eevey and Ketchup. Notably, Young Eevey placed 7th at Albion 4, the highest placement for a Bowser Jr. player at a national tournament, while Ketchup picked up notable wins over several top players. Even following the online era, players such as Yoda Cage have seen relatively high placements at major tournaments. This has since led to a reevaluation, with many players believing the character is mid-tier and nowhere near as bad as initially perceived. Bowser Jr. is ranked 72nd on the first and current tier list.

Classic Mode: Mama Peach, Where Are You?[edit]

Bowser Jr.'s congratulations screen.

Most of Bowser Jr.'s opponents are princesses, some of which are teamed up with their love interest (or in Lucina's case, her father). The title refers to the event of Super Mario Sunshine where Bowser Jr. called Peach his "mama".

Role in World of Light[edit]

Bowser Jr.'s location in World of Light.
Finding Bowser Jr. in World of Light

While Bowser Jr. and the Koopalings do not appear in the World of Light opening cutscene, they were all vaporized and later imprisoned alongside the rest of the fighters (except Kirby) when Galeem unleashed his beams of light.

Bowser Jr. and the Koopalings were among the many fighters that fell under Dharkon's control upon Galeem's first defeat. Bowser Jr. is found in one of two alternating pathways on the Triforce of Power segment of the Sacred Land sub-area, guarded by various Legendary spirits.

As a side note, once Bowser Jr. is rescued, the Koopalings (due to their status of being alternate characters of Bowser Jr.), will have been 'rescued' as well, resulting in them also being available as playable characters within the story.

Bowser Jr.'s fighter spirit can be obtained by completing Classic Mode. It is also available periodically for purchase in the shop for 300 Gold, but only after Bowser Jr. has been unlocked. Unlocking Bowser Jr. in World of Light allows the player to preview the first spirit below in the Spirit List under the name "???". As a fighter spirit, it cannot be used in Spirit Battles and is purely aesthetic. Each of the Koopalings possess their own fighter spirits, which can only be obtained by purchase in the shop. Each fighter spirit has an alternate version that replaces them with their artwork in Ultimate.

Bowser Jr. also appears as a primary spirit in the form of Shadow Mario.

Alternate costumes[edit]

Instead of alternate color schemes, Bowser Jr.'s alternate costumes consist of the Koopalings. Bowser Jr.'s Junior Clown Car is the only one with black eyes and horizontal orange "eye paint", while the Koopalings' Clown Cars have yellow mechanical eyes with vertical black "eye paint". All of the Koopalings have their own models and voice clips.

Fighter Showcase Video[edit]


  • The "Everyone is Here!" trailer features a visual glitch: when Lemmy uses his down taunt, his face disappears for a few frames at the end of the animation.
    • The Junior Clown Car also shows a visual glitch, with two mouths overlapping each other when Ludwig is seen falling off a ledge.
  • The render of Lemmy resembles artwork of him from New Super Mario Bros. U, which is the same artwork used for his fighter spirit, and he is the only Koopaling to be completely out of the Junior Clown Car.
  • Bowser Jr., Yoshi, R.O.B., and Mr. Game & Watch are the only characters who used their default costumes in one of the spirit battles present at the game's initial release. In Bowser Jr.'s case, it is because of the Shadow Mario spirit.
    • Despite that, there's no proper battle against a default Bowser Jr. in World of Light outside of himself because the only Spirit Battle in which he is present (Shadow Mario) is absent, instead finding puppet fighters of the Koopalings. The only exception to this are the false Bowser Jr.s created during battles involving Dharkon. This also applies to Cloud.
      • Additionally, Ludwig was the only Koopaling not present in any spirit battle until the DLC Toy-Con Car Spirit was introduced.
      • Alongside Mr. Game & Watch, R.O.B and Yoshi., Bowser Jr. is one of the few characters with a Spirit battle where all of his alternate costumes appear in a single Spirit fight.
  • Prior to version 1.1.0, Bowser Jr.'s airdodge behaved exactly how it did in Smash 4 when using it out of Abandon Ship!, making him the only character to have been capable of performing multiple airdodges without touching the ground or getting hit in any version of Ultimate.
  • When the game's speed is slowed down, Bowser Jr.'s Final Smash becomes noticeably more effective, hitting more times and dealing more damage. At 1/4 speed it potentially becomes one of the strongest Final Smashes in the game.
  • Bowser Jr., Banjo & Kazooie, Pyra/Mythra, and Kazuya are the only characters whose artworks on all alternate costumes on the official website do not cast a shadow.
  • Bowser Jr. is the only character to have motion blur in their render (at the Clown Car's propeller).
    • Lemmy is the only Koopaling without motion blur in his render.
  • In the Sound Test, Larry is the only Koopaling with one less voice clip than Bowser Jr. and the other Koopalings. This is due to both his teching and carrying being the same voice clip.
    • Morton also had this distinction in Smash 4.
  • If Bowser Jr.'s right-inputted victory pose is performed by any Koopaling besides Roy, the propeller will stop after looping once during the post-animation.[1]
    • A similar situation also occurred during Bowser Jr.'s clapping animation on the No Contest screen in Smash 4.
  • Even though Morton's eye mark has been changed to a lighter gray in this game, his stock icon still shows it as the dark gray it was in Smash 4.
  • When the Franklin Badge or Screw Attack items are equipped, if Bowser Jr. does his side taunt, the item will clip through the clown car. This does apply to the other Koopalings.
