R.O.B. (ロボット, Robot) is a playable character in Super Smash Bros. Ultimate. He was confirmed as a playable character on June 12th, 2018. R.O.B. is classified as fighter #42.

R.O.B.'s beeping sound effects from Brawl and Smash 4 were repurposed for Ultimate.

How to unlock

Complete one of the following:

• Play VS. matches, with R.O.B. being the 31st character to be unlocked.
• Clear Classic Mode with Pikachu or any character in its unlock tree, being the 3rd character unlocked after Shulk.
• Have R.O.B. join the player's party in World of Light.

With the exception of the third method, R.O.B. must then be defeated on Wrecking Crew.

Attributes

R.O.B. is the seventeenth heaviest character in the game, being tied with Snake, thus making him a heavyweight. R.O.B. sports average mobility: he has the thirty-third fastest walking speed, thirty-ninth fastest dashing speed and average initial dash, twenty-sixth fastest air speed, thirtieth highest air acceleration, and the forty-eighth highest traction. R.O.B. also has the thirty-ninth highest falling, fast falling speeds, and gravity.

Like in Brawl and Smash 4, R.O.B. is a zoning-oriented character with very useful projectiles to keep his opponents at bay. Robo Beam enables him to attack from considerable distance, and becomes the noticeably stronger Super Robo Beam when it is left idle for 14.3 seconds. While Robo Beam interrupts opponents faster, Super Robo Beam deals more damage and has higher knockback growth. Gyro is an auto-chargeable projectile that becomes an item when fired. Compared to Robo Beam, it has a more favorable angle for disrupting opponents, while also being more manipulable as a projectile and having greater KOing potential. Thanks to R.O.B.'s item throws being among the strongest in the game, Gyro is also very useful when smash thrown as an item.

Aside from his offensive prowess with projectiles, R.O.B. also does not have issues against projectiles, courtesy of Arm Rotor's ability to reflect them with greater strength than they initially had. In addition to its reflection ability, Arm Rotor now boasts KO potential, thanks to its finishing hit having significantly higher knockback growth.

R.O.B's ground game is very good, Jab comes out on frame 3 and acts as a quick move at low percents to escape pressure situations, it can also jab lock and combo. Forward tilt can be useful for spacing at higher percents since it comes out on frame 7, but its' usefulness ends there. Up tilt comes out on frame 4, and is very good for acting as an anti air and combos into up air, which can kill. Down tilt is R.O.B.'s single best move, it lowers his hurtbox a little bit, it has great range, more range than forward tilt and jab, it ties with jab as R.O.B.'s fastest move at frame 3, its total active frames is only 14, meaning it is one of the most safe to spam moves in the game, the move pressures shields and the only thing that can punish the move out of shield is frame 5 or faster up b moves like Fire and Dolphin Slash, the move trades with shield grabs, the move also combos into itself at lower percents and at higher percents it can start comboing into grab or dash attack, and at even higher percents it can send opponents into a jab lock scenario for a kill at relatively low percents, these jab locks are notoriously hard to react to because of the very low launch angle for down tilt and the low knockback. Lastly dash attack is useful for punishing landings and whiffs, the move is very fast at frame 7, has lots of range, and can combo into forward air at low to mid percents.

R.O.B.'s air game is also strong, thanks to the excellent and disjointed ranges of all but one of his aerials. Neutral aerial has large, disjointed hitboxes that make it great for covering the opponents options if they lack the range to deal with it, it's also very hard to punish out of shield, due to its damage, total landing lag (7 frames), and range despite its speed and autocancel window. It is also a reliable combo starter at low to medium percentages when SHFF'd, as well as a useful spacing option. Up aerial is R.O.B.'s least useful aerial over all however it is one of his best options for covering the space above him, thanks to its usefulness in harassing airborne opponents due to its large and long lasting hitboxes and its strength despite the surprising speed of the move. Back and down aerials are R.O.B.'s most damaging aerials when sweetspotted, and have large hitboxes like neutral aerial. However, they also boast specific strengths: the former has recovery potential thanks to it propelling R.O.B. forward slightly, and it is R.O.B.'s only aerial that can kil in neutral due to the safety of the move thanks to its power, great hitbox size and the distance he gains when using it, whereas the latter is a meteor smash that can hit below the ledge and kill very early if done so, it is also active for a total of 6 frames. Lastly, forward aerial is R.O.B.'s fastest aerial coming out on frame 6, this makes it very spammable in neutral due to how low committal it is to use, as R.O.B. can act right after the move ends, however its hitbox has much shorter range and isn't disjointed.

Unlike in Brawl, R.O.B. now boasts respectable KO potential. Like his up aerial, back aerial, up throw and Arm Rotor, R.O.B.'s smash attacks now boast KO potential, thanks to being buffed in various ways. Forward smash's sweetspot deals slightly more damage and higher knockback. Although forward smash's other hitboxes deal less damage, they have been re-positioned farther outward, which improves its range. Up smash's sweetspot and down smash also deal more damage and, like forward smash, have had their hitboxes tweaked for the better: up smash now has hitboxes on R.O.B.'s arms that launch the opponent into its thruster hitboxes, whereas down smash is now a semi-spike and sends opponents at a consistent trajectory as opposed to launching them in a random direction.

R.O.B.'s grab game has also improved. Forward and back throws are still limited in regard to utility, but are nevertheless decent for spacing and setting up edge-guards, back throw however, can kill at the ledge at very high percents, and both can combo into dash attack or gyro at very low percents. In comparison, R.O.B.'s up throw is much more useful. Up throw is his most damaging throw; a very viable KOing option, especially when boosted by rage; and can even be used for combos at low percentages. However, down throw is possibly his least useful throw, down throw deals poor damage, and buries opponents, however with mashing the opponent can typically get out before R.O.B. has any chance to act, the throw does, however, gain some use at percents past 125%, where R.O.B. can 50/50 mix up with short hop up air or up smash, depending on if the opponent mashes or not, and at around 154% the up smash becomes a true combo.

Although R.O.B. possesses a number of useful traits, he also has some noteworthy shortcomings. Despite his KO potential's drastic improvements, landing his KOing options can still be problematic because of them being laggy and/or having unimpressive ranges. The latter trait is particularly noticeable in regard to R.O.B.'s arm-based attacks, most of which have hitboxes that have either become smaller and/or tweaked for the worse. For example, his grab game is hindered by his overall grab range now being the shortest in the game because of his much smaller grabboxes, whereas his up tilt has drastically less utility because of its adjusted hitboxes.

In addition to R.O.B.'s hitbox issues, his hurtbox also hinders him, it is very large and wide, meaning he can get hit by a lot of things that other characters such as Pichu would have an easier time getting away from. This also means he is susceptible to combo-oriented characters, such as Mario and Palutena. This is further compounded by his aerials' inability to reliably break combos: neutral and down aerials are too slow, forward and up aerials only hit in front of and above R.O.B., respectively, and back aerial has both slow start-up and only hits behind him.

While R.O.B.'s zoning game remains his greatest strength, the universal nerf to projectile camping has somewhat toned it down. Gyro, in particular, has been the most adversely affected of his projectiles: in addition to retaining its susceptibility to being stolen, a fired Gyro deals drastically less damage and covers less range. The removal of glide tossing also significantly hinders its approach potential. Robo Beam's nerfs are not as severe in comparison, but are nevertheless noticeable: it now deals slightly less damage, and both it and Super Robo Beam travel slower. As a a result of these nerfs, R.O.B. now has a more difficult time dealing with most characters that have better projectiles (such as Young Link and Pikachu); attacks that counteract his own projectiles (such as Fox and Mr. Game & Watch); or both (such as Wolf).

Changes from Super Smash Bros. 4

R.O.B. has been significantly buffed overall in his transition to Ultimate. Similarly to Mario, R.O.B. has received comparatively few major changes in his transition from the previous game; however, most of these changes have majorly improved his toolkit, and he benefits from the changes made to the game's engine as well.

Arguably R.O.B.'s most impactful buff is towards his Arm Rotor. Previously universally regarded as one of the worst attacks in SSB4, it has reduced start-up lag, much less endlag and faster execution, and larger hitboxes and improved angles that connect with each much better. This not only significantly improves its use as an edgeguarding option, but when combined with the other changes made to his moveset, it has now become one of the most devastating combo finishers in Ultimate, granting R.O.B. potential zero-to-death combos and allowing him to KO opponents at early percentages.

Several of R.O.B.'s attacks have received quality of life changes that improve their utility. Forward smash and back aerial deal more knockback, granting them increased KO potential and toning down one of R.O.B.'s previous weaknesses. Up tilt has had its first hit's hitbox from Brawl restored, increasing its range and reliability. Down smash now launches opponents at a consistent angle, improving its consistency all around. Robo Beam has larger hitboxes and launches at lower angles, improving their effectiveness as edgeguarding options. Lastly, Gyro has been significantly buffed: it can now be returned to the dock once R.O.B. has grabbed it to charge it again and fire it with less startup, as opposed to tossing it once he has grabbed it. It can also now be jump canceled. These changes grant R.O.B. even more potential combo routes and give him more safe options against opponents.

R.O.B. benefits from most of the universal changes to the game's engine. The universal increase in mobility and the ability to use any attack out of a run cancel allows R.O.B. to close out the distance more effectively and compounds his improved up-close game. The universal decrease to landing lag noticeably improves R.O.B.'s combo game as well; aside from changes made to his Arm Rotor, they make up aerial's looping hits more viable for starting combos, and neutral aerial's reduced start-up lag coupled with its decreased landing lag noticeably improves its combo potential and makes it a safer option when landing. Lastly, the changes to air dodging benefit R.O.B., as they allow him to edgeguard opponents more effectively, and allow R.O.B. to air dodge out of Robo Burner to gain more distance, improving his recovery.

However, R.O.B. has received a few nerfs as well. His grab game has been weakened overall, with universal changes to grabs hindering the safety of his grabs despite his improved standing grab. His up throw has increased endlag, making follow-ups harder, and his down throw now buries, allowing for read-based follow-ups at high percents, but removing any guaranteed set-ups at low to mid percents, particularly his effective down throw-up air combo, dubbed the "Beep Boop". R.O.B. also retains a few of the same issues from his previous incarnation; his unusually large size and lack of fast aerial options leave him susceptible to juggling (with the buffs to his neutral air failing to fully address this issue), his up-close game is still exploitable due to R.O.B.'s lack of attacks with disjointed range, and his recovery remains predictable and easy to hit him out of with a sufficiently ranged move.

Overall, R.O.B.'s playstyle remains fundamentally unchanged from SSB4, but changes to several of his attacks and to the game's engine have now properly cemented R.O.B. as the "jack-of-all-trades" between his fellow zoning brethern, as they give him having a far deadlier punish game compared to both of his previous incarnations. R.O.B.'s results in the early metagame of Ultimate have been the strongest of any of his incarnations thus far, thanks to the efforts of notable players such as 8BitMan, Dill, OCEAN, Raffi-X, WaDi and Zackray. This has lead to a strikingly positive reception from the competitive Smash community, with most players viewing him as a high-tier character, in comparison to his mid-tier status in both Brawl and Smash 4.

Aesthetics

• As with all veterans returning from SSB4, R.O.B.'s model features a more subdued color scheme. His body has a duller matte finish, and his eyes are less reflective. As a result, he more closely resembles the original peripheral.
• R.O.B.'s eye expressions are now seen properly at all times, as in Super Smash Bros. for Nintendo 3DS.
• During his side taunt, R.O.B. now emits purple flashing sparkles from his eyes instead of white.
• Dash, double jump, and prone animations has been altered.

Attributes

• R.O.B.'s character model was shrunken. This makes his hurtbox slightly smaller, while keeping his range mostly intact.
• Like all characters, R.O.B.'s jumpsquat animation now takes three frames to complete (down from 5).
• R.O.B. walks slightly faster (1.122 → 1.178).
• R.O.B.'s initial dash speed is much faster (1.3 → 2.002).
• R.O.B. dashes slightly faster (1.568 → 1.725).
• R.O.B.'s air speed is slightly higher (1.08 → 1.134).
• R.O.B.'s traction has been increased (0.06 → 0.105).
• Spotdodge has reduced endlag (FAF 27 → 26).
• Backward roll has more endlag (FAF 30 → 35).
• Neutral air dodge has increased endlag (FAF 33 → 51).
  • Neutral air dodge has less landing lag (22 frames → 10).
• The re-introduction of directional airdodges notably benefit R.O.B: they improve his recovery, as he can airdodge out of Robo Burner to mix-up his recovery or reach the edge after he has ran out of fuel. They also improve his edgeguarding ability due to his useful aerial game and the buffs to Arm Rotor.

Ground attacks

• Neutral attack:
  • Its first hit can be held for a consecutive jab.
  • Both hits have gained additional hitboxes (3.5u → 2.5u/2.5u/2.8u/2.8u (hit 1), 3.5u → 3.4u/3.4u/3.6u (hit 2)), improving its range.
  • The first hit has altered knockback (4 (base)/70 (scaling) → (18/23)/15) allowing both hits of neutral attack to connect easier.
  • The first hit's angles have been altered (100° → 361°/180°), allowing it to lock opponents.
• Forward tilt:
  • The move deals more damage (5%/6% (arm)/8% (arm's tip) → 7%/8% (arm)/10% (arm's tip)).
  • The move has altered knockback (30 (base)/100 (scaling) → 48/77). This makes the move safer on hit at low percentages, but slightly reduces its KO power.
  • Forward tilt now uses stationary hitboxes rather than connecting the hitboxes to R.O.B.'s arm.
• Up tilt:
  • R.O.B. no longer faces the screen directly during the move much like his taunts.
• Dash attack:
  • It has reduced ending lag (FAF 35 → 31), improving its combo potential.
• Forward smash:
  • The move has altered hitbox placements (Z offset: 12u → 14u (close), 22u → 24u (mid)), increasing the horizontal range of both the closest hit and mid hit.
  • It has increased knockback scaling (close: 100 → 105, mid/far: 100 → 110).
  • Its charging animation has been changed to resemble its animation in Brawl. This makes the move safer to execute when charging, as R.O.B. doesn't lean forward.
• Down smash:
  • The side of which down smash launches opponents is no longer inconsistent; the front hits always launch in front of R.O.B. and vice versa.
  • The multi-hits are now stationary, improving the consistency of their range.
  • The multihits have less knockback (30 (base)/40 (scaling) → 20/20), allowing them to connect into each other more reliably.
  • It only hits 3 times instead of 5, slightly reducing its overall damage output up close despite the first hits dealing more damage (2% (hits 1-4 base)/1.5% (hits 1-4 tip) → 3.5% (hits 1-2 base)/3% (hits 1-2 tip); total: 13%/11% → 12%/11%).

Aerial attacks

• All aerials have less landing lag (12 → 7 frames (neutral), 15 → 9 frames (forward), 22 → 13 frames (back and up aerials), 21 → 12 frames (down).
• Neutral aerial:
  • The move has faster startup (frame 18 → 14) with a longer duration (frames 18-32 → 14-32).
  • It deals more damage (8% (base)/6% (tip) → 9.5%/7.5%).
  • The sourspot hitbox now takes priority over the sweetspot hitbox. This makes the sourspot easier to land for combos, but makes the sweetspot harder to land for KOing.
• Forward aerial:
  • Forward aerial has a longer duration (frames 6-7 → 6-8).
• Back aerial:
  • The move deals more damage (12% (base)/10% (tip)/6% (late base)/4.5% (late tip) → 15%/13%/9%/7.5%) with knockback not fully compensated on the base hit (32 (base)/100 (scaling) → 41/87 (base), 32/100 → 35/83 (tip), 30/100 → 35/76 (late base), 30/100 → 35/74 (late tip)). This noticeably improves its KO potential.
  • As a result of its higher damage, the move slows down R.O.B. for longer upon hitting a shielding opponent.
  • The late hit has a longer duration (frames 24-29 → 24-32).
• Up aerial:
  • Up aerial's final hit comes out quicker (frame 26 → 23).
    • This allows the final hit to connect better with the initial hits.
    • The move's duration has been unchanged, resulting in increased endlag overall.
• Down aerial:
  • R.O.B. faces further forward when performing his down aerial.
  • R.O.B. is given greater vertical speed upon activating the aerial (0.1 → 0.7), allowing R.O.B. to use the move closer to the ground and not land before the hitbox comes out, and improving the move's stalling potential in general.

Throws/other attacks

• Grabs:
  • Standing grab and pivot grab have slightly reduced start-up (frame 7 → 6 (standing), frame 11 → 10 (pivot)).
  • All grabs have increased endlag (FAF 30 → 37 (standing), FAF 37 → 45 (dash), FAF 36 → 40 (pivot)).
  • Standing grab has more range (Z2 offset: 10.6u → 11.6u).
  • Dash grab and pivot grab have less range (Z2 offset: 12.7u → 12.2u (dash), -18.1u → -17.3u (pivot).
• Pummel
  • R.O.B. has a new pummel: he headbutts the opponent instead of squeezing them in his grip.
    • This new pummel deals less damage (2% → 1.3%).
    • However, this pummel has faster startup (frame 2 → 1), deals more hitlag (4 → 14 frames) and has reduced ending lag (FAF 17 → 7). This increases the amount of times R.O.B. can pummel the opponent before throwing them or before they break out.
• Forward throw:
  • R.O.B. has a new forward throw where he throws the opponent overhead with his arm.
    • Forward throw's animation change has R.O.B. release the opponent later (frame 7 → 11) with its duration unchanged, reducing its endlag. Compounded with R.O.B.'s improved initial dash, this grants the move limited followup potential at low percentages.
• Back throw:
  • R.O.B. has a more dynamic animation and now turns to face the direction in which he threw the opponent.
• Up throw:
  • Up throw rises higher during the animation.
  • Up throw releases the opponent earlier (frame 66 → 59) with its duration unchanged, increasing its endlag. This hinders its combo ability past low percentages.
• Down throw:
  • Down throw now buries opponents briefly.
    • This allows for more read-based followups, including up tilt and up aerial, and gives R.O.B. a new KO confirm into up smash.
    • The new, more consistent attack sacrifices the potential for early KO's that 'Beep Boop' could achieve in Smash 4, although it is still possible at low percentages or if the opponent doesn't mash out fast enough.
  • Down throw deals much less damage (10% → 5%).
  • Down throw has increased endlag (FAF 66 → 76).

Special moves

• Robo Beam
  • Super Robo Beam deals significantly more damage (10% (Super Robo Beam)/17% (point-blank Super Robo Beam) → 15%/22%) with knockback scaling compensated (70 → 43).
  • Both stages of Robo Beam have larger hitboxes (1.5u → 2u (Robo Beam), 3u → 3.5u (Super Robo Beam)).
  • Both stages of Robo Beam launch opponents at lower angles (Robo Beam: 80° → 60°, Super Robo Beam: 60° → 45°). This makes them better for edgeguarding.
  • Super Robo Beam's graphic is flashier.
  • Both stages of Robo Beam deal negative shield damage (0 → -2.2 (Robo Beam), 0 → -3.7 (Super Robo Beam)), effectively dealing half of their shield damage.
• Arm Rotor
  • The move has faster startup (frame 16 → 13) and significantly reduced endlag (54 frames → 41).
  • Arm Rotor is executed much faster (FAF 110~137 → FAF 86~108), improving its safety offstage.
  • The multihits now have set knockback (20 (base)/70 (scaling) → 40 (set)/65 (scaling)), use an autolink angle (120°/145°/145°/361° → 367°) and have a noticeably reduced hitlag multiplier (0.7× → 0.2×). Additionally, the move in general has slightly larger hitboxes (multi-hits: 3.3u/3.3u/3.3u/4.3u → 3.3u/3.3u/4u/4.5u, final hit: 5.5u → 6u), and the final hit extends further inwards (Z offset: -4–14 → -4.5–14). These changes allow the move to connect significantly more reliably, make it harder to escape from, and allow it to hit behind R.O.B better, increasing the move's reliability.
  • Akin to its Brawl counterpart, Arm Rotor has much less horizontal maneuverability on the ground.
  • Arm Rotor deals more damage per hit (1% → 1.5%), but has an increased rehit rate (3 frames → 5), reducing its overall damage output if all hits connect (16%-25% → 10.5%-18%).
  • Arm Rotor's finishing hit animation has been altered: it is now more exaggerated.
  • The final hit has a reduced hitlag multiplier (3.4× → 2.4×).
• Robo Burner
  • R.O.B. now has a gauge on his chassis that shows how much fuel he has left for Robo Burner.
  • Robo Burner has new particle effects.
  • Robo Burner can be jump cancelled.
  • Robo Burner can be cancelled immediately into an air dodge if one is available.
• Gyro
  • If R.O.B. grabs a Gyro he's previously thrown or dropped, it can be returned to its dock and charged again. This allows him to store his Gyro in a similar manner to Pocket, reducing the opportunity for his opponents to use it against him, and allowing him to keep up the pressure with it for a longer period of time.
  • Gyro can now be jump cancelled while charging.
  • Gyro deals less shield damage.
• Final Smash:
  • R.O.B. has a new Final Smash called Guided Robo Beam, in which he fires multiple small red beams that ricochet and home in on enemies, before firing a larger green beam that enlarges at the last second.
  • This is an improvement over Super Diffusion Beam, as it is much easier to hit opponents.

Update History

R.O.B has recieved a mix of buffs and nerfs.

1.1.0

• Removed instant Gyro Cancelling.

2.0.0

• Arm Rotor connects more reliably.

3.0.0

• Robo Beam deals less shield damage.
• Gyro deals less shield damage.

3.1.0

• Neutral attack 1 connects into neutral attack 2 more reliably as the first hit's 180° hitbox has higher base knockback (18 → 40). This notably also allowed the move to lead into a down tilt which could begin a loop (jab → down tilt, jab → down tilt etc.) known as the "Robble".
• Neutral attack 2 has more range.

4.0.0

• Neutral attack 1's 180° hitbox has less base knockback (40 → 23) and hitstun, no longer being able to lead into a down tilt loop.

Moveset

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

		Name	Damage	Description
Neutral attack			3%	Two alternating hooks. Both of its hits hit on frame 3, which ties it with down tilt as R.O.B.'s fastest attack. Its first hit can be repeated by holding the attack button, and can also jab lock opponents, while the second hit is useful for spacing.
			3%
Forward tilt			8% (arm), 10% (arm's tip)	A lunging hook. This attack can be angled; the tip of R.O.B.'s arm is decent for spacing, beginning at 50%.
Up tilt			3% (hit 1), 5% (hit 2)	Thrusts his arms upward. It is good for starting combos into itself, up smash and up aerial from low to medium percentages, or functioning as an anti-air attack. However, it has very minimal horizontal range, which forces R.O.B. to practically stand next to a grounded opponent in order to land it.
Down tilt			5%	Thrusts his arms low along the ground. It hits on frame 3, which ties it with neutral attack as R.O.B.'s fastest attack. Although it has a small chance to trip opponents, its overall fast speed largely offsets this and makes it an excellent set-up option.
Dash attack			7%	A double forearm club. It can be followed up with forward aerial if the opponent's reaction is read properly.
Forward smash		S3	15% (base), 11.5% (middle), 6% (tip)	An optical energy blast, similar to the uncharged Robo Beam. It can be angled; has very high knockback growth; and its base hitbox deals respectable damage. Altogether, these enable it to KO middleweights at 109% near the edge. Although slightly weaker, its middle hitbox is still strong enough to KO middleweights at 136% near the edge. However, its range is merely average at best, it has high ending lag and the blast's tip has extremely minimal KO potential.
Up smash			3% (hit 1), 14% (hit 2)	Performs a handstand and activates his thrusters to emit a fiery blast upward. It hits on frame 10, which is somewhat fast for a smash attack. It also has deceptive horizontal range on the ground, thanks to R.O.B.'s arms having hitboxes that launch opponents into the thrusters' hitboxes, the latter of which are fairly powerful. Its base KOs middleweights at 113%, whereas its tip KOs them at 116%. Altogether, these traits make it a reliable KOing option, especially from out of shield. However, it has high ending lag.
Down smash			3.5% (hits 1 and 2), 5% (hit 3)	Lowers his torso and spins it around rapidly while outstretching his arms to perform a series of discus clotheslines, similarly to Arm Rotor. It hits on frame 7, which is very fast for a smash attack. Thanks to it being a semi-spike and its last hit's very high knockback growth, it KOs at middleweights at 129% while near the edge, and is very effective for edge-guarding. However, its base hitboxes launch the opponent behind R.O.B., which means that he must face away from the edge when attempting to use this move in order to properly launch the opponent off-stage. Like forward and up smash, it also has high ending lag.
Neutral aerial		AirN	9.5% (base), 7.5% (tip)	Activates his thrusters to somersault and emit a fiery blast in a circular motion. Its large hitbox, very minimal landing lag and ability to auto-cancel with a short hop collectively make it very useful for spacing, approaching and starting combos. Due to it hitting on frame 14, however, it is one of the slowest of its type and is punishable if it is not spaced properly.
Forward aerial			7%	A double forearm club. It hits on frame 6, making it R.O.B.'s fastest aerial. It is also ideal for spacing when SHFF'd, has minimal landing lag and is decent for edge-guarding. However, it lacks KO potential because of its average damage output and very low base knockback. It is also R.O.B.'s only aerial that does not have a disjointed hitbox.
Back aerial		Air Boosters	15% (base), 13% (middle), 9% (late base/middle)	Leans forward and activates his thrusters to emit a fiery blast behind himself. Very high power, but is very slow, coming out on frame 18 and has several sourspots. It also is unable to autocancel in a short hop. Back aerial can also be used for horizontal recovery, as it slightly propels him forward and does not consume Robo Burner's fuel.
Up aerial			1.5% (hits 1 - 4), 4% (hit 5)	Rapidly rotates his arms upward, ending it with an upward double forearm club. It hits on frame 7, making it R.O.B.'s second fastest aerial. It is down throw's most reliable follow-up from low to medium percentages. It is also useful for juggling and KOing, as its loop hits keep the opponent trapped reliably, whereas its last hit's extremely high knockback growth enables it to KO middleweights at 115% while near the upper blast line. It can also auto-cancel with a short hop.
Down aerial			12% (base), 11% (middle), 6% (tip)	Activates his thrusters to emit a fiery blast downward. The middle portion of the blast is a powerful meteor smash, which makes it a very potent edge-guarding option, especially after an edge trump if the opponent re-grabs the edge. Auto-cancels in a short hop due to it stopping R.O.B's momentum. Due to it hitting on frame 20 and having 43 frames of ending lag, it is R.O.B.'s slowest aerial. When coupled with its 12 frames of landing lag, it is punishable if it is not spaced properly and auto-canceled, though not to the same extent as in SSB4.
Grab			—	Clinches the opponent.
Pummel			1.3%	A headbutt.
Forward throw			8%	While holding the opponent in his "hand", R.O.B. pulls his arm back and then flings it forward, throwing them away.
Back throw			10%	Flings the opponent behind him with both of his arms. If fully charged beforehand, Gyro can follow up from a back throw from low to mid percentages.
Up throw			12%	Performs a jet-propelled reverse piledriver.
Down throw			5%	R.O.B. flips the opponent over and drills them into the ground headfirst, burying them.
Floor attack (front)			7%	Punches around himself while getting up.
Floor attack (back)			7%	Punches in front of himself and then behind himself while getting up.
Floor attack (trip)			5%	Spins his torso around to throw a low-angle hook around himself while getting up.
Edge attack			9%	Swings his base forward and activates his thrusters to emit a fiery blast forward while climbing up. Despite the appearance, it doesn't possess a flame hitbox.
Neutral special		Robo Beam	7% (Uncharged Robo Beam), 11.5% (Robo Beam, point-blank), 4.5% (Robo Beam, long range), 22% (Super Robo Beam, point-blank), 15% (Super Robo Beam, long range)	An optical laser with 3 different levels: Uncharged Robo Beam, Robo Beam, and Super Robo Beam. Uncharged Robo Beam is a very small energy blast instead of a laser, and can only damage opponents at point-blank range. However, it can be fired consecutively and has deceptively high knockback growth, which allow it to ward off nearby opponents. Conversely, both Robo Beam and Super Robo Beam can damage opponents from afar and ricochet, but cannot be fired consecutively. Robo Beam and Super Robo Beam also deal noticeably more damage when fired at point-blank range. It is one of R.O.B.'s options for zoning alongside Gyro, with Robo Beam being better for his neutral game, while Super Robo Beam is better for surprising opponents. The light on R.O.B.'s head indicates the level: a dim, slow-paced pulsating glow indicates an Uncharged Robo Beam; a brighter, moderate-paced pulsating glow indicates Robo Beam; and a bright, rapid-paced pulsating glow indicates Super Robo Beam.
Side special		Arm Rotor	1.5% (loop), 3% (final hit) 1.5× reflected projectile	Rapidly spins his torso around to perform a series of discus clotheslines that concludes with an uppercut. Mashing the special button extends the duration of the move. It can also reflect projectiles and move R.O.B. forward or backward while the control stick is tilted in the respective direction.
Up special		Robo Burner	0%	Activates his thrusters in order to fly. It grants impressive vertical and horizontal recovery distance, although R.O.B. has a set amount of fuel, indicated by the gauge in his chassis, to use in order to perform this move. Fuel is recovered over time as long as R.O.B. is grounded. This doesn't cause helplessness, allowing R.O.B. to fast fall, air dodge, or attack with any aerials or any of his other specials either through its duration or after its conclusion. R.O.B. is also immune to footstool jumps while using this move, although other characters can still jump off of him regardless. It also grants intangibility on frames 2-4, but only when performed on the ground.
Down special		Gyro	6.1%-8.7% (uncharged), 7.2%-10.8% (fully charged), 5% (idle Gyro)	Charges a spinning top on his base. R.O.B.'s other zoning option alongside Robo Beam, it can be picked up and thrown as an item after making contact with either the opponent or the stage. However, opponents can do the same and thus use the top against him. Only one Gyro can be active at a time, and attempting another will result in R.O.B. flailing in confusion. If R.O.B. is holding his Gyro, he will be able to charge it again. Typically, an idle Gyro deals little knockback when touched, (albeit enough to harass anyone trying to get past), but it can lock.
Final Smash		Guided Robo Beam	1.2% (homing lasers), 1% (laser loop), 3% (enlarged laser loop)	Re-configures his body into a cannon-like form, and begins to charge energy. During the charge, he fires smaller red lasers that home on opponents in front of him. He then unleashes the built up energy in the form of a green laser, which can be angled up or down. As the Final Smash begins to end, the laser briefly enlarges, becoming wider and more powerful.

Victory poses

• Left: While advancing forward, R.O.B. rotates his "hands" outward while his arms point out straight. After halting, he spins his arms in alternating directions and rotates his head 360° counterclockwise. Afterwards, he adjusts his arms to face upward, continuously raising and lowering them in a flexing gesture. R.O.B.'s head also rotates 360° clockwise after every 2 times he pumps his arms.
• Up: Hovers in the air, spins, and lands. He then proceeds to continuously lower and raise his arms while rotating his head.
• Right: Turns his head and flashes the lights in his eyes while clapping. He then proceeds to continuously clap, lowering his arms after each clap.

In the NES game Stack-Up, the first game that the R.O.B. accessory was compatible with, this track would play before starting memory mode. In this remix, a short intro is added, and the first part is repeated once.

Role in World of Light

Finding R.O.B. in World of Light

Although R.O.B. does not appear in the World of Light opening cutscene, he was vaporized and later imprisoned alongside the rest of the fighters (sans Kirby) when Galeem unleashed his beams of light.

R.O.B. was one of the many fighters that fell under Dharkon's control upon Galeem's first defeat. He can be found in the Mysterious Dimension sub-area, as the fighter closest to the entrance, standing in a floating island with scattered mechanical junk. To reach him, the player must first defeat the spirit of Redd as the answer to a trivia question ("Which of these spirits sells furniture?"), allowing access to the island he's in.

Spirits

R.O.B.'s Fighter Spirit can be obtained by completing Classic Mode. It is also available periodically for purchase in the shop for 500 coins. Unlocking R.O.B. 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 Fighter Spirit has an alternate version that replaces them with their artwork in Ultimate.

Additionally, R.O.B. makes an appearance in a few Support Spirits.

Trivia

File:Regiggas ROB Japan.jpgFile:Regiggas ROB USA.jpg

A comparison of Regigigas Spirit battle in the
Japanese, Chinese and Korean versions (left) vs.
other languages (right), showing the difference
between language versions on R.O.B.'s default
costumes.

• R.O.B.'s stock icon is one of four to show eyes, the others being Kirby, Meta Knight, and Sonic.
• On the official site for Ultimate, each character is accompanied by a background image of a stage from their universe. As R.O.B. is the only character to not have a stage from his home universe, his page is the only one with no stage for the background image.
• R.O.B. is one of four characters to have appeared since Brawl to have a different Final Smash across every installment; the other three are Pit, Zero Suit Samus, and King Dedede.
  • Coincidentally, all four are Brawl newcomers.
• R.O.B., Cloud and Ice Climbers are the only fighters that cannot receive a series bonus since they don't have any primary spirits from their own series.
• R.O.B. is one of the few characters in the game that uses his default color scheme in a spirit battle alongside Mr. Game & Watch, Bowser Jr., Yoshi, Peach, Mario, Luigi, Inkling, Robin and Joker due to the Ancient Minister spirit battle.
  • Out of all of these characters, Bowser Jr., Yoshi, Mr. Game & Watch, and R.O.B. are the only ones who used their default costumes in spirit battles through one of the 1297 spirits available when the game first launched.
  • This is not counting Alph or female Corrin.
  • Due to the Regigigas, Ancient Minister, Chibi-Tot, and Mumbo Jumbo spirit battles, R.O.B. is the only character whose color scheme used for a spirit battle changes based on the language version used.
• R.O.B.'s NES color scheme is the only one which bears the NES' base sticker which reads "Robotic Operating Buddy"; all other palettes bear the Famicom base sticker, which reads "Family Computer Robot". Famicom is short for "Family Computer."
