'''Luigi''' ({{ja|ルイージ|Ruīji}}, ''Luigi'') is a playable character in ''[[Super Smash Bros. Ultimate]]''. He was confirmed alongside {{SSBU|Yoshi}} and the rest of the [[veteran]]s on June 12th, 2018 during E3 2018, with him and Yoshi being the last two veterans to be revealed. Like in his appearances prior to ''[[Super Smash Bros. 4]]'', he is an [[unlockable character]] instead of being a [[starter character]]. Luigi is classified as [[Fighter number|Fighter #09]].

As in ''SSB4'', {{iw|wikipedia|Charles Martinet}}'s portrayal of Luigi from ''[[Super Smash Bros. Brawl]]'' was repurposed for ''Ultimate''.

==How to unlock==
Complete one of the following:
*Play [[VS. match]]es, with Luigi being the 33rd character to be unlocked.
*Clear {{SSBU|Classic Mode}} with {{SSBU|Mario}} or any character in his unlock tree, being the 5th character unlocked after {{SSBU|Ike}}.
*Have Luigi join the player's party in [[World of Light]].
Luigi must then be defeated on [[Luigi's Mansion]] (the [[Ω form]] is used in World of Light).

==Attributes==
Luigi is a [[Weight|middleweight]] whose attributes deviate from most other characters in his weight class. Luigi sports fairly average [[walk]]ing speed, [[dash]]ing speed, and [[air acceleration]], a decent initial dashing speed, below-average [[gravity]], slow [[falling speed]], low [[traction]], the 2nd slowest [[air speed]], and the 4th highest [[jump]]s. As a result, Luigi is quite [[floaty]] and his mobility is fairly sluggish overall, especially in the air.

Luigi's greatest asset is his outstanding frame data, which is easily among the fastest in the game. Because of this, similarly to [[Mario (SSBU)|his older brother]], Luigi can be very difficult to punish; only two of his standard moves and five of his attacks overall have more than 9 frames of startup lag (forward smash, down aerial, [[Fireball]], [[Green Missile]], and [[Luigi Cyclone]]), a multitude of his moves hit on or before frame 5 (such as neutral attack, dash attack, neutral aerial, up aerial and his tilts), and the vast majority of his moveset has low ending lag, granting him incredible attack speed and an excellent punish game; both points are complemented by the utility of his overall moveset. Neutral attack's damage output and [[range]] are average at best, yet its first two hits can [[lock]]. Its first hit also comes out on frame 2, which makes the move a fairly useful option for warding off nearby opponents. Luigi's tilt attacks also have their own perks: forward tilt can be angled and is useful for spacing, up tilt has excellent combo and juggling potential, and down tilt is an incredibly quick and highly [[spam]]mable move that can combo into itself and many other moves while also being able to consistently perform [[2 frame punish]]es at the edge. Lastly, Luigi's dash attack has quick startup; when coupled with its reduced ending lag, increased damage output and higher knockback, it is a much better move for approaching and attacking than in previous games.

Luigi's smash attacks are among the fastest of their kind, have below-average ending lag, and are strong enough to be reliable finishers. As a result of these traits, they allow Luigi to quickly and effectively punish opponents close to him while also rendering him being difficult to punish on shield. Forward smash deals extra [[shield damage]], up smash is an effective anti-air attack due to rendering Luigi's head [[intangible]] while its hitboxes are active, and down smash is very useful for punishing rolls thanks to its minimal lag, respectable damage output, and long range. Both up smash and down smash also have set-up potential at low percentages if Luigi successfully covers the opponent's options afterward.

Luigi's aerial attacks are also very useful, having fast startup, lenient [[auto-cancel]] windows, quick [[interruptibility]] (except for neutral and back aerials) and low ending lag in general. In terms of auto-canceling, he can auto-cancel all his aerials with a short hop, can auto-cancel forward, back, up and down aerials with a short hop fast fall, and can use forward, up and down aerials twice with a single short hop. Lastly, he can use his forward and up aerials twice with a single short hop without suffering from landing lag. Neutral aerial is a [[sex kick]] and, like in previous installments, the only one that launches opponents vertically, which benefits its clean and late hitboxes: the former is a great combo breaker and deals high damage and good knockback, making it a reliable KO option at high percentages, and both are very useful combo starters when [[SHFF]]'d, with the latter working even up to high percentages. Forward aerial has the fastest duration of its kind and launches at the [[Sakurai angle]]; at low to medium percentages, these traits make it very reliable for [[approach]]ing or down throw-initiated combos into itself, neutral aerial and up aerial, as well as a reliable [[edge-guarding]] option at high percentages. Back aerial has the highest ending lag of Luigi's aerials by a noticeable margin, but its minimal startup, decent range and powerful clean hitbox collectively enable it to function as a safe and reliable option for KOing, edge-guarding and (when used via a [[reverse aerial rush]]) approaching. Up aerial is useful for combos: it can either extend them or, thanks to having the lowest amount of landing lag out his aerials, use its clean hitbox to start them at low percentages when SHFF'd due to its clean hit dealing above-average damage for a combo move. Its generous auto-cancel window and very low ending lag also allow Luigi to use it twice in a single short hop and still auto-cancel it successfully, a trait it shares with his forward aerial and {{SSBU|Little Mac}}'s neutral aerial. Lastly, down aerial is safe to use and has a clean hitbox which is a fast meteor smash, coming out on frame 10 and with only 18 frames of ending lag, the lowest of any meteor smash. Due to his powerful aerials with generally low lag all around, Luigi has an outstanding air game.

Luigi has an excellent grab game, but unlike in past installments, he has a [[tether grab]] due to using the {{iw|mariowiki|Poltergust G-00}}'s {{iw|mariowiki|Suction Shot}} to grab an opponent. As a result, Luigi can grab opponents from a fairly long distance, preventing the necessity for him to get up close to do so. It also provides Luigi with a [[grab aerial]], in which the suction cup functions as a projectile that deals minor damage and knockback. This grants Luigi an additional edge-guarding option and deceptively useful combo move that, unlike most projectiles, cannot be absorbed or reflected. Like Mario, Luigi has an average pummel, which can deal multiple hits before being followed up with any of his useful throws. Forward throw deals respectable damage and is useful for repositioning opponents or setting up edge-guards against them at high percentages. Back throw also deals respectable damage and great knockback, allowing it to KO at a mere 120% or even earlier with [[rage]]. Unlike Mario's back throw, it also lacks a noticeably long animation, which makes it noticeably more difficult for the opponent to offset it with [[DI]]. Up throw deals average damage and knockback, and possesses follow-up potential into forward or up aerials at low to medium percentages, depending on the opponent's DI. It also possesses a collateral hitbox to hit bystanders. Lastly, down throw is Luigi's primary combo starter and is one of his most useful attacks: it deals average knockback, has low ending lag, and launches at a vertical angle, which collectively enable it to lead into potent and highly damaging combos, even being able to lead into potential [[zero-to-death]] combos. Down throw can combo into moves such as up tilt, up smash, all of Luigi's aerials, Super Jump Punch and Luigi Cyclone, due to its aforementioned traits. It also functions as an excellent setup for KOs, such as by comboing into Super Jump Punch, back aerial, or Luigi Cyclone at high percentages. Although situational, down throw also has a collateral hitbox before the throw that can hit bystanders, similarly to up throw.

As a pseudo-[[clone]] of Mario, Luigi has two special moves that are derived from his older brother, yet his versions deviate in noticeable ways. [[Fireball]] is a [[projectile]] that is useful for pressuring, hindering an opponent's approach, or setting up an attack. Unlike Mario's Fireball, Luigi's is unaffected by gravity and moves up and down, which makes it somewhat less effective at hindering an opponent's [[recovery]] attempt, but allows it to cover a consistent area horizontally and vertically. Compared to Mario's version, Luigi's Fireballs also have a clean hit that deals more damage and they have less ending lag, allowing him to throw another one just one frame before the clean hit ceases. [[Super Jump Punch]] has fast startup like Mario's, but propels him vertically instead of diagonally. By extension, it consists of a sweetspot and sourspot, instead of multiple hitboxes like Mario's. Its sweetspot boasts devastating power, which makes it a very potent punishment option, yet it is very risky because of its high ending lag and sourspot that is mostly useless outside of being a niche gimping tool.

Aside from these, Luigi's other special moves are completely distinct from Mario's. [[Green Missile]] deals damage and covers horizontal distance, both of which can be increased thanks to its ability to be [[charge]]d, giving KO potential to the fully charged version. However, it also has a one-in-ten [[random]] chance of misfiring; in this case, it becomes even stronger than the fully charged version, and travels much further. Lastly, [[Luigi Cyclone]] grants Luigi some [[invincibility]] frames on startup, enabling him to break out of combos or contest opposing attacks effectively. It also functions as a KOing option near the upper [[blast line]], and is a guaranteed follow-up out of down throw even at high percentages, which can function as a reliable KO confirm (especially on platforms).

However, Luigi has some notable disadvantages. He has fairly sluggish mobility, with his extremely slow air speed and floaty physics making it difficult for him to land onstage, especially against faster characters, thus giving him a notable weakness to [[juggling]]. His range, even compared to Mario's, is well below-average and thus he struggles to approach characters with ranged or disjointed attacks, such as {{SSBU|Lucina}} and {{SSBU|Shulk}}. Compared to Mario, Luigi's lack of a [[reflect]]or also makes it more difficult for him to deal with [[projectile camping]] (especially against characters such as {{SSBU|Link}}, {{SSBU|Samus}}, and {{SSBU|Simon}}) when combined with his awkward mobility.

Additionally, Luigi's poor aerial mobility hinders his ability to approach with his aerial attacks, as well as his recovery. On top of this, his recovery, although long-distanced, is linear, slow, predictable and fairly susceptible to [[gimp]]ing. Luigi Cyclone barely grants any additional height compared to previous games, which leaves him reliant on [[Super Jump Punch]] and [[Green Missile]] for recovering; the former travels directly upward only, and the latter has noticeable lag, cannot [[Edge sweet spot|sweetspot edges]], and relies on either charging or its random misfire chance to cover a serviceable horizontal distance.

Overall, Luigi is a very solid character, though he often tends to run hot and cold, unlike his brother. His extremely fast frame data, strong air game, and devastating combos make him a force to be reckoned with, provided his opponents make careless mistakes. Luigi's overall combo game, KO potential, and advantage state are easily superior to his Mario's, having many different set-ups that can deal absurdly high damage within seconds, and then score KOs immediately thereafter. However, Luigi's short range, mediocre grounded mobility, abysmal aerial mobility, and predictable side and up specials force him to fight at close-quarters all the time, hindering both his approach and recovery. Because of this, a mastery of Luigi's recovery mixups and powerful combo game is crucial to achieving success with him.

==Changes from ''[[Super Smash Bros. 4]]''==
Luigi has received a mix of buffs and nerfs in his transition from ''SSB4'' to ''Super Smash Bros. Ultimate'', but was nerfed slightly overall. While Luigi received numerous buffs and changes that improve his strengths and benefit him, he has also suffered from a few major nerfs; both points are also affected by the universal changes to the game's engine, which were a mixed bag for him.

Luigi's direct nerfs have affected his playstyle quite noticeably. Particularly, [[Luigi Cyclone]] travels much less vertical distance via [[button mash]]ing, removing all of its usefulness for [[recovery]], as even with very fast mashing, Luigi barely gets any additional distance at the end of the move. Alongside the addition of windboxes to it, this also removes its ability to [[gimp]] opponents and KO them at virtually any percentage if timed correctly, which was a crucial technique to his success in ''SSB4''. 

Another notable example comes from his new grabs: although they still have only moderate ending lag for their range, they possess much more startup, and are more prone to punishment due to the ability to cancel [[spot dodge]]s earlier into attacks. This makes them much riskier to use and harder to land, especially since their increased startup removes many guaranteed setups into them and severely weakens Luigi's ability to [[shield grab]], consequently limiting his defensive game and the usage of his pivotal down throw.

In terms of indirect nerfs, the changes to [[air dodging]] have both helped and hindered Luigi, but hurt him overall: due to his floatiness, the reintroduction of directional air dodges allows him to use one for recovery in a pinch. However, due to his below-average gravity, his air dodges have drastically more ending lag relative to the rest of the cast, thus making them more punishable, and recovery mix-ups with them are almost unfeasible due to the ability to only use one before landing. When combined with his [[air speed]] remaining the second worst in the game, as well as the severe distance nerf to Luigi Cyclone, his recovery is much more linear and easier to intercept, causing Luigi to become much more prone to [[edge-guarding]] and early offstage KOs, despite Super Jump Punch and fully charged Green Missile granting slightly more distance.

However, Luigi has also received several buffs, with said buffs being of greater quantity than his nerfs. In particular, some of his least useful moves in ''SSB4'' have been significantly improved: [[down tilt]] can be interrupted twice as fast and deals less knockback, allowing it to poke opponents much more safely and increasing its combo potential, while his [[dash attack]] has considerably decreased ending lag, connects more consistently, and has increased power, making it much safer and more reliable as a burst option while its higher power gives it utility as a potential KO option near the edge at high percentages. Additionally, his existing KO options have been improved overall: [[forward smash]], [[up smash]], [[down aerial]], sweetspotted [[Super Jump Punch]] and [[Luigi Cyclone]] all have increased knockback, forward smash and [[down smash]]'s launching angles are much more favorable for KOing outright and edge-guarding, down smash's sweetspots out-prioritize its sourspots, and [[back throw]] is much harder to DI than the previous back throw due to its much faster release.

Further complementing these changes, Luigi's already excellent combo game has been improved as well: his new [[up tilt]] has less ending lag and more range in front of and above him compared to his previous up tilt, [[up aerial]] has less ending lag, and [[down throw]] leads to deadlier combos, having more consistent KO setups and even potential [[zero-to-death]] combos due to its redistributed damage output, lower ending lag and Luigi's faster [[jumpsquat]]. Lastly, Luigi Cyclone has received far more utility overall to compensate for its recovery potential being removed: in addition to its aforementioned higher knockback, it inflicts more damage, pulls opponents in more consistently thanks to its new [[windbox]]es, connects more reliably, has increased range, and grants [[invincibility]] on startup. The addition of the Poltergust G-00 to Luigi's moveset also grants him much longer ranged [[grab]]s alongside a [[grab aerial]], the latter of which can be used as a [[spacing]] tool, start and/or extend combos, as well as even edge-guard opponents.

Luigi also benefits from some of the universal changes. Like the rest of the veterans, Luigi has had decreased [[landing lag]] in all his aerial attacks, a faster [[jumpsquat]] (now having a 3 frame jumpsquat like the rest of the cast), and his mobility enhanced in most areas, but most importantly, his infamously low [[traction]] has been greatly increased, which somewhat alleviates his problems with [[approach]]ing and significantly improves his out of shield options. The increased [[shieldstun]] on grounded moves in comparison to ''SSB4'' makes Luigi harder to punish on some of his moves, notably his newly improved down tilt. In addition, unlike most characters, Luigi has increased [[falling speed]] and [[gravity]], making him less vulnerable to juggling while the latter increases his jump speed, allowing him to more easily take advantage of his buffed down throw and combo game when combined with his faster jumpsquat.

Overall, Luigi has become even more polarizing than in ''SSB4'': while his combo and KO capabilities have been improved, ''Ultimate''{{'}}s game engine and nerfs to crucial aspects of his toolkit have made it harder for him to take advantage of his strengths and render him easier to KO due to his worsened recovery. Luigi has achieved decent tournament success in ''Ultimate'' so far, with respectable representation from players such as {{Sm|Elegant}} and {{Sm|SMB}}, though as a whole, his tournament results are not as dominating as they were in ''SSB4''. This has lead to a positive reception of Luigi, although his reception has been slightly more mixed: several top players, such as {{sm|Dabuz}}, {{sm|Mew2King}}, {{sm|ESAM}}, {{sm|VoiD}}, {{sm|Samsora}}, and {{sm|ZeRo}}, view him as either an upper mid tier character or a high tier character. As for now, Luigi's true viability remains uncertain, although he is still considered a viable choice.

==Update history==
Luigi received a mix of buffs, nerfs and glitch fixes via game updates, but was buffed slightly overall. Update {{SSBU|1.1.0}} decreased his up aerial's ending lag, which improved its combo potential and restored its ability to auto-cancel with a short hop like in ''SSB'' and ''Brawl''. Update {{SSBU|2.0.0}} granted Luigi a handful of buffs, with the most notable being a noticeable increase to [[Luigi Cyclone]]'s knockback. Thanks to this buff, Luigi Cyclone now functions as a reliable KO confirm from down throw at high percentages when used on platforms.

Aside from this, Luigi received a few quality of life buffs: his up smash's knockback was increased, [[Green Missile]]'s ending lag was decreased, and both his standing and pivot grabs gained 1 more active frame apiece. However, this update harmed Luigi more so than helped him by removing his down aerial's ability to [[meteor smash]] grounded opponents, which reverted it to how it functioned in ''SSB4''. This nerfed most of its combo potential, particularly in regard to its consistency at performing [[zero-to-death]] combos.

As part of update {{SSBU|3.0.0}}'s near-universal nerf to [[projectile]]s, [[Fireball]]'s [[shield damage]] output was decreased. Update {{SSBU|3.1.0}} improved his grab aerial's range by repositioning its plunger, and slightly improved his neutral attack's consistency. However, an adjustment to the timing of Luigi Cyclone's [[invincibility]] resulted in its utility being worsened slightly. Lastly, update {{SSBU|10.1.0}} noticeably improved his dash attack's consistency by decreasing its looping hits' knockback and adjusting its penultimate hit's angles. When coupled with the damage output buff it received in the transition to ''Ultimate'', Luigi's dash attack has become more reliable both as a burst option and as a risky, yet viable KO option.

Overall, Luigi fares mildly better than he did at the launch of ''Ultimate''. Although down aerial's combo potential was worsened noticeably, his combo game remains potent thanks to the retention of his other inherent strengths, up aerial's ending lag being decreased, and Luigi Cyclone's KO potential improving.

{{MovesetTable
|game=SSBU
|neutralcount=3
|neutralname=Jab ({{ja|ジャブ|Jabu}}) / Straight ({{ja|ストレート|Sutorēto}}) / Rump Thrust ({{ja|どんけつ|Donketsu}})
|neutral1dmg=2%
|neutral2dmg=2%
|neutral3dmg=4%
|neutraldesc=A {{iw|wikipedia|one-two combo}} followed by a [[wikipedia:Professional wrestling attacks#Hip attack|hip thrust]]. Its first hit comes out on frame 2 and its last hit slightly moves Luigi forward, making it a safe option at close range. The first 2 hits can also [[jab lock]] an opponent. The first 2 hits are based on the {{iw|mariowiki|Punch}} + Punch + {{iw|mariowiki|Kick}} combo from ''{{iw|mariowiki|Super Mario 64}}''.
|ftiltname=Middle Kick ({{ja|ミドルキック|Midoru Kikku}})
|ftiltdmg=9%
|ftiltdesc=A hook kick. Despite having a different animation compared to {{SSBU|Mario}}'s, it can be angled like his and has similar properties. Thanks to its higher damage output, it can function as a situational KO option while near the edge at very high percentages. Just like Luigi's other tilts, it comes out on frame 5. Good spacing option despite having less range and more ending lag than Mario's. However, it is outperformed by other stronger and more versatile spacing tools.
|utiltname=Cat Uppercut ({{ja|ねこアッパー|Neko Appākatto}})
|utiltdmg=6%
|utiltdesc=An uppercut. It is a potent combo starter, leading into itself at low percentages and all of Luigi's aerials at medium to high percentages. Due to its generous hitbox and low lag, it is one of Luigi's better [[juggling]] options. Compared to Mario's version, it deals more damage, has more frontal range and less ending lag, but its much lower base knockback makes it less safe at very low percentages.
|dtiltname=Heel Kick ({{ja|かかとげり|Kakato Geri}})
|dtiltdmg=5%
|dtiltdesc=A crouching, low-angle heel kick. It has short range, and deals low damage and knockback. However, its very minimal lag allows it to combo into itself, forward tilt, dash attack and forward smash at very low percentages. Its ability to be used in very quick succession can also enable it to whittle down shields if the opponent is close enough to Luigi, as he can act as soon as he puts his foot back to the ground. It is also an excellent edge trapping tool, since its aforementioned speed makes it a fairly effective [[2 frame punish]] that can pressure the opponent's edge options. 
|dashname=Flurry Punches ({{ja|ぽこぽこパンチ|Pokopokok Panchi}})
|dashdmg=2% (hits 1-4), 4% (hit 5)
|dashdesc=A flurry of childish punches. Unlike in previous games, it has significantly less ending lag and both its damage output and knockback are noticeably higher, to the point that it can function as a situational KO option while near an edge at very high percentages. Due to its first hit coming out on frame 4, it is also one of the fastest dash attacks in the game in regard to startup alongside {{SSBU|Ivysaur}} and {{SSBU|Fox}}'s dash attacks. Since Luigi dashes forward, it has fairly long range, but it is very punishable if whiffed.
|fsmashname=Hell Thrust ({{ja|地獄突き|Jigoku Tsuki}})
|fsmashdmg={{ChargedSmashDmgSSBU|15}}
|fsmashdesc=A knifehand thrust. Luigi's most powerful smash attack, thanks to its respectable damage output, very high knockback scaling on all angles, and considerable [[shield damage]] output. Due to it coming out on frame 12, it is Luigi's slowest grounded attack. Despite this, its startup makes it one of the fastest forward smashes in the game; this is further supplemented by it having relatively low ending lag for a smash attack (28 frames). It also possesses a high shield damage output, which can make it challenging to punish. However, it has short range, which can make it difficult to land.
|usmashname=Lead Headbutt ({{ja|スマッシュヘッドバット|Sumasshu Heddobatto}}, ''Smash Headbutt'')
|usmashdmg={{ChargedSmashDmgSSBU|14}} (head), {{ChargedSmashDmgSSBU|12}} (body)
|usmashdesc=An upward arcing headbutt. Due to it coming out on frame 9, it is fairly quick for a smash attack, and is one of Luigi's fastest KO options. Like Mario and {{SSBU|Dr. Mario}}'s up smashes, it renders his head [[intangible]] throughout its duration. Unlike theirs, however, it consists of a sweetspot and a sourspot, the latter of which inflicts 2% less damage and is located closer to Luigi. Despite this, the sourspot is out-prioritized by the sweetspot, and is very unlikely to hit unless the opponent is practically touching him. Compared to Mario's version, it launches at a fairly lower angle, but actually KOs earlier due to its overall higher knockback. Like Dr. Mario's version, its hitbox lasts for 1 frame longer than Mario's version, giving it more frontal range and a longer period of intangibility. In addition, its animation ends 1 frame earlier. Its combination of very fast interruptibility, the intangibility on Luigi's head and respectable power make it very hard to punish, especially from out of shield.
|dsmashname=Double Kick ({{ja|ダブルキック|Daburu Kikku}})
|dsmashdmg={{ChargedSmashDmgSSBU|15}} (body), {{ChargedSmashDmgSSBU|14}} (legs)
|dsmashdesc=A modified {{iw|mariowiki|Sweep Kick}}. Due to it coming out on frame 6, it is Luigi's fastest smash attack. It is useful for punishing rolls, thanks to it hitting in front of Luigi and behind himself; the back hit also has noticeably higher knockback compared to the front hit. Its respectable damage output also makes it useful for edge-guarding, and enables it to KO at reasonable percentages while near the edge. In an opposite fashion to his up smash, both hits possess sweetspots located closer to Luigi, with the sourspots covering the rest of his legs. Unlike in ''SSB4'', its front hit is significantly more reliable for KOing and edge-guarding, thanks to it launching the opponent at 52° instead of 120°.
|nairname=Luigi Kick ({{ja|ルイージキック|Ruīji Kikku}})
|nairdmg={{ShortHopDmgSSBU|12}} (clean), {{ShortHopDmgSSBU|6}} (late)
|nairdesc=A flying kick. It comes out on frame 3, which is the fastest startup out of Luigi's aerials and, in turn, makes it very useful for breaking out of combos. It also launches at a vertical angle; this enables its late hit to start combos reliably with a landing short hop, and enables its clean hit to potentially KO at high percentages while near the upper blast line. Despite being able to auto-cancel with a short hop like Luigi's other aerials, it is his only aerial that cannot do so with a [[SHFF|short hop fast fall]].
|fairname=Crown Chop ({{ja|脳天チョップ|Nōten Choppu}})
|fairdmg={{ShortHopDmgSSBU|8}}
|fairdesc=A downward knifehand strike. It comes out on frame 7 and is interruptible only 13 frames after the hitbox's active frames conclude (frame 24), making it the fastest forward aerial in the game in regard to ending lag. It is a reliable follow-up from down throw at low to medium percentages, and is useful for edge-guarding due to its extremely low ending lag, with the fastest interruptibility of its type. It also auto-cancels on frame 21; when combined with its minimal startup and lack of ending lag, these traits make it a useful approach option, since it can auto-cancel with a short hop fast fall or can be used twice with a short hop without incurring landing lag. Its hitbox is positioned on Luigi's hand and arm, but it also has a smaller hitbox on his shoulder that covers slightly around his body.
|bairname=Rear Drop Kick ({{ja|後方ドロップキック|Kōhō Droppu Kikku}})
|bairdmg={{ShortHopDmgSSBU|14}} (clean feet), {{ShortHopDmgSSBU|8}} (clean legs, late)
|bairdesc=A dropkick. It has decent range, to the point that it has the second longest range among Luigi's aerial attacks. The clean hit's sweetspot is located on Luigi's feet and deals high damage and knockback, making it one of Luigi's best KOing options. The clean hit's sourspot and the late hit deal much less damage and knockback; as a result, they are much less effective for KOing, yet more useful for partaking in combos. It comes out on frame 6, but its 33 frames of ending lag is the highest amount out of Luigi's aerials. It can auto-cancel both with a short hop and with a short hop fast fall, although in the latter case, it requires strict timing to do so.
|uairname=Air Slash ({{ja|エアスラッシュ|Ea Surasshu}})
|uairdmg={{ShortHopDmgSSBU|11}} (clean), {{ShortHopDmgSSBU|7}} (late)
|uairdesc=A bicycle kick. It is useful for combos like Mario's up aerial, due to its very low ending lag and landing lag. Its clean hitbox also inflicts above-average damage for a combo-oriented move. However, it launches at a lower angle than Mario's; this makes it less effective for juggling and especially vertical combos past low percentages, yet more effective for horizontal combos. It also comes out 1 frame later than Mario's, on frame 5 instead of 4, but has less ending lag. However, it possesses a substantially smaller hitbox. Just like his forward aerial, Luigi can use his up aerial twice with a single short hop, as well as auto-cancel it due to its lenient auto-cancel window and low ending lag.
|dairname=Drill Kick ({{ja|ドリルキック|Doriru Kikku}})
|dairdmg={{ShortHopDmgSSBU|10}} (clean), {{ShortHopDmgSSBU|8}} (late)
|dairdesc=A corkscrew double foot stomp. It comes out on frame 10 and auto-cancels with a short hop fast fall. Its clean hit is a respectably strong [[meteor smash]] against airborne opponents, and it has the lowest ending lag (14 frames) of any meteor smash in the game alongside minimal landing lag. Altogether, these traits make it a fast, yet safe edge-guarding option and a versatile move overall. However, the clean hit only affects the hitbox on Luigi's feet and only lasts for 1 frame. Although the late hit is less rewarding due to launching opponents horizontally away from Luigi, it is still quite effective for edge-guarding. Prior to update 2.0.0, the clean hit could affect both grounded and aerial opponents, which allowed it to start combos at a wide variety of percentages, even possessing KO set-ups into Super Jump Punch. As of update 2.0.0, the meteor smash hitbox only affects aerial opponents, removing most of its potential as a combo starter. Despite this, it remains a valuable combo extender from down throw or late neutral aerial, since it can launch opponents down to the stage and thus provide more follow-ups. It resembles the {{iw|mariowiki|Drill Stomp}}.
|zairname=Suction Shot ({{ja|空中オバキューム|Kūchū Obakyūmu}}, ''Aerial Poltergust'')
|zairdmg=5%
|zairdesc=Uses the {{iw|mariowiki|Poltergust G-00}} to [[mariowiki:Suction Shot|fire a suction cup attached to a rope]]. Despite its appearance, it cannot be used as a tether recovery. The suction cup and its rope also detach from the Poltergust G-00 after being fired, with the suction cup functioning like a projectile thereafter. The suction cup is affected by gravity and cannot be [[reflect]]ed or [[absorb]]ed; altogether, these traits make it useful for edge-guarding. The suction cup uniquely will appear and act the same regardless of whether Luigi grabbed in the air or missed a grab the ground. The suction cup will descend a set distance and then disappear thereafter; it will also disappear shortly after landing on the ground. However, using Luigi's grab aerial will not restrict him from using his grounded grabs while the prior suction cup is active. Luigi's grab aerial has much higher landing lag (20 frames) compared to other grab aerials, but this can be circumvented if he lands before firing the suction cup, as it can come out and then hit opponents during its landing lag. Doing this allows the suction cup to combo into several grounded attacks while he sufficiently close to the opponent. Overall, its attributes make it a good projectile and a useful part of Luigi's moveset.
|grabname=Suction Shot ({{ja|つかみ|Tsukami}}, ''Grab'')
|grabdesc=Uses the Poltergust G-00 to fire a suction cup attached to a rope. Like other tether grabs, it has long range; unlike most tether grabs, it has fairly low ending lag, to the point that Luigi is able to act out of it before the suction cup disappears.
|pummelname=Poltergust Shock ({{ja|オバキュームショック|Obakyūmu Shokku}}
|pummeldmg=1.3%
|pummeldesc=Vacuums the opponent with the Poltergust G-00. It is much quicker, yet much less damaging than Luigi's previous pummel.
|fthrowname=Slam ({{ja|オバキューム投げ|Obakyūmu Nage}}, ''Poltergust Throw'')
|fthrowdmg=9%
|fthrowdesc={{iw|mariowiki|Slam}}s the opponent forward with the Poltergust G-00. It is Luigi's second most damaging throw, but has limited utility outside of dealing damage and setting up edge-guards at high percentages. It can KO middleweights at around 162% at the edge of Final Destination.
|bthrowname=Slam ({{ja|オバキューム反転投げ|Obakyūmu Hanten Nage}}, ''Reverse Poltergust Throw'')
|bthrowdmg=10%
|bthrowdesc=Turns around to slam the opponent behind himself with the Poltergust G-00. It is Luigi's most damaging and strongest throw, as well as one of the strongest back throws in the game, to the point of being able to reliably KO middleweights under 120% while near an edge.
|uthrowname=Poltergust Reel ({{ja|オバキューム釣り|Obakyūmu Tsuri}})
|uthrowdmg=8% (throw), 6% (collateral)
|uthrowdesc=Swings the Poltergust G-00 upward to fling the opponent overhead. It can combo into forward aerial or up aerial at low to medium percentages, depending on the opponent's [[DI]]. It also possesses a collateral hitbox that launches bystanders upward alongside the thrown opponent. However, it is a much less versatile combo starter compared to down throw, and is much less effective for KOing compared to back throw.
|dthrowname=Poltergust Drop ({{ja|オバキュームドロップ|Obakyūmu Droppu}})
|dthrowdmg=3% (hit 1 and throw)
|dthrowdesc=Shoves the opponent under himself and {{iw|mariowiki|Ground Pound}}s them. It is easily Luigi's best throw and arguably his best move overall, thanks to its average knockback, low ending lag and 80° launching angle collectively making it one of the best combo starters in the game. It can combo into several moves, including up tilt and up smash at low percentages, as well as any of Luigi's aerials and Luigi Cyclone at low to high percentages. Its most effective follow-up at low percentages is clean down aerial, followed by a neutral aerial into another clean down aerial, before concluding with up aerial into an aerial Super Jump Punch for a [[zero-to-death combo]] that works on a wide variety of characters. At high percentages, it has several potential KO setups, including aerial Super Jump Punch, back aerial (while near the edge), and aerial Luigi Cyclone (when used on a platform or if the opponent uses subpar DI). In addition to its combo potential, it has a collateral hitbox before the throw on frames 18-28 that can hit bystanders. Due to its low ending lag, Luigi can act as soon as he touches the ground. 
|floorfname=&nbsp;
|floorfdmg=7%
|floorfdesc=Performs a modified Sweep Kick before getting up.
|floorbname=&nbsp;
|floorbdmg=7%
|floorbdesc=Performs a modified Sweep Kick before getting up.
|floortname=&nbsp;
|floortdmg=5%
|floortdesc=Performs a side kick and then a wheel kick while getting up.
|edgename=&nbsp;
|edgedmg=9%
|edgedesc=Performs a double-footed legsweep while climbing up.
|nsname=Fireball
|nsdmg=6% (clean), 5% (late)
|nsdesc=Tosses a {{iw|mariowiki|Green Fireball}}. It is fairly [[spam]]mable, which enables it to pressure opponents from afar and hinder approaches. Compared to Mario's Fireball, Luigi's version has less ending lag and has a clean hit that deals more damage, with Luigi being able to toss another Fireball when the clean hit ceases. Unlike Mario's version, Luigi's Fireball is unaffected by gravity, which gives it more vertical range at the cost of being less suitable for edge-guarding.
|ssname=Green Missile
|ssdmg=≈6.16% (uncharged), ≈21% (fully charged), 25% (misfired)
|ssdesc=Crouches and then propels himself forward to perform a flying [[Wikipedia:Professional wrestling attacks|battering ram]]. It takes more than a full second to fully charge, but deals impressive damage upon doing so. Upon reaching full charge, it has KO potential and can be held for some time before being automatically canceled. It also has a 10% chance to misfire, which deals considerably more damage and knockback, KOing opponents at ≈60% from the center of {{SSBU|Final Destination}}; this is known as Overzealous Green Missile. A misfired Green Missile, also grants intangibility on frames 18-22, and always travels the same distance regardless of the charge. However, its considerable ending lag makes it punishable whether it is used for offense or recovering, which makes [[read]]s very important in order to use it effectively.
|usname=Super Jump Punch
|usdmg=25% (grounded sweetspot), 20% (aerial sweetspot), 1% (sourspot)
|usdesc=A jumping uppercut. Its grounded sweetspot emits a [[ping]] sound and triggers a [[Special Zoom]] upon hitting, and boasts excellent damage output with impressive knockback, KOing opponents from 37%-67% depending on weight from ground level. Its aerial sweetspot is larger, yet deals less damage and knockback (though it is still powerful), and does not have the special effects of the grounded sweetspot. Both versions also grant intangibility for 3 frames (starting on frame 8 on the ground and on frame 6 in the air). However, it is very punishable because of its high landing lag, while its abysmally weak sourspot lacks KO potential and is very unsafe.
|dsname=Luigi Cyclone
|dsdmg=2% (hits 1-4), 4% (hit 5)
|dsdesc=Spins around rapidly, to the point of generating a vortex around himself that traps an opponent and damages them with a series of [[Wikipedia:Professional wrestling attacks#Clothesline|discus clotheslines]] and [[Wikipedia:Professional wrestling attacks#Spinning back fist|spinning backfists]] before assuming a [[wikipedia:Spreadeagle (position)|spread-eagle position]] to launch them. It allows Luigi to move horizontally on the ground, as well as maintain his aerial position by mashing the special move button, although both abilities are considerably weaker than in previous games. It also grants Luigi [[invincibility]] during startup (frames 4-8 while grounded and 1-7 in midair), and has [[windbox]]es around Luigi that pull opponents into the attack. These traits make it a more effective, yet slightly less rewarding combo breaker compared to his neutral aerial. As of update 2.0.0, Luigi Cyclone's final hit has respectable power: the grounded version KOs middleweights at ≈160%, whereas the aerial version is a reliable KO confirm from down throw at high percentages, especially when used on a platform. Although Luigi Cyclone connects more reliably than in previous games, it should also be noted that it now requires consistent button mashing for all of its hits to connect.
|fsname=Poltergust G-00
|fsdmg=30.1% (maximum captured), 10% (ejection)
|fsdesc=Wields the Poltergust G-00 to vacuum nearby opponents into it before powerfully ejecting them diagonally. Opponents will accumulate more damage the earlier they are vacuumed in. It has decent range, and is capable of vacuuming opponents from a variety of angles.
|dtauntname=
|dtauntdmg=2%
|dtauntdesc=Bashfully kicks to the ground. Its high fixed knockback value makes it a very potent meteor smash, allowing it to potentially OHKO an edge-hanging opponent. The grounded meteor smash mechanics of ''Ultimate'' also make it surprisingly potent as a combo starter on-stage, as it can no longer be teched. However, it is held back by pitiful range and slow startup.

===[[On-screen appearance]]===
*A green {{iw|mariowiki|Warp Pipe}} appears, and Luigi leaps out of it while saying "Let's-a go!" nervously and sporting a frightened expression that heavily resembles [https://www.mariowiki.com/Luigi%27s_Mansion#/media/File:Luigi's_Mansion_Box.png his appearance on the cover artwork] of ''{{iw|mariowiki|Luigi's Mansion}}''.

===[[Taunt]]s===
*'''Up taunt''': Performs 5 poses in very quick succession. When switching from pose to pose he says, "Hoh, hah, hee, heh, hoo!"
:#Flashes the {{iw|wikipedia|V sign}}. This pose resembles the one he assumes upon collecting an item in ''Luigi's Mansion''.
:#Points both his fingers in the direction he is facing, looking frightened.
:#Holds his finger under his nose and looks toward the screen. This pose heavily resembles the one he assumes in [https://www.mariowiki.com/Gallery:Mario_%26_Luigi:_Partners_in_Time#/media/File:Luigi_MLPiT.png his individual artwork] for ''{{iw|mariowiki|Mario & Luigi: Partners in Time}}''.
:#Crouches down to the floor with his back turned to the player. This pose heavily resembles [https://www.mariowiki.com/Gallery:Mario_Golf_(Nintendo_64)#/media/File:LuigiBogey.PNG his Bogey animation] from the [[mariowiki:Mario Golf (Nintendo 64)|Nintendo 64 version of ''Mario Golf'']].
:#Assumes a scared expression and pose with his hands on his cheeks. This pose heavily resembles his appearance on the cover artwork of ''Luigi's Mansion''.
*'''Side taunt''': [[Wikipedia:Planking (fad)|Planks]] while saying "Pow pow!" Due to this taunt moving Luigi forward into the [[Hitbox#Hitboxes in three dimensions|z-axis]] and lowering his hurtbox, some attacks may actually miss him as a result.
*'''Down taunt''': Bashfully kicks the ground while sighing. It is one of the few taunts in the game to inflict damage; it deals 2% and [[meteor smash]]es opponents with high [[set knockback]], making it a surprisingly reliable combo starter onstage and allowing it to [[one-hit KO]] opponents who are off-stage or hanging on an edge. It is similar to the animation Luigi performs when he loses a {{iw|mariowiki|minigame}} in ''{{iw|mariowiki|Mario Party 2}}''.

*'''Left:''' [[Wikipedia:Planking (fad)|Planks]] twice, much like in his side taunt and his artwork in ''[[SSB4]]''. His nose twitches in brief intervals after the second plank.
*'''Up:''' With his back to the screen and his hands on his hips, Luigi nods his head twice. Then, he turns around and makes gun motions with his fingers, saying "Bang, bang!" He continues to alternate between pointing his fingers and nose to the right and left.
*'''Right:''' Childishly flails his arms about in the air, first towards his right side and then his left. Afterwards, now exhausted, he gasps while holding his left hand out and resting his right hand on his knee. This is similar to his "character chosen" animation in ''SSB'' and his dash attack, albeit with a different ending animation.

==In [[competitive play]]==
Initially, Luigi was seen as noticeably inferior to his appearance in ''SSB4''. This is because some of Luigi's most useful tools from the previous game were significantly nerfed: Luigi's new grab was initially viewed rather negatively because it had more lag, and [[Luigi Cyclone]] almost lost the ability to grant vertical distance when mashed, weakening Luigi's recovery and removing Luigi's Cyclone ability to gimp. Although Luigi initially had a zero-to-death combo with his down throw and aerial, update 2.0.0 would make it harder to perform. This, along with mediocre results at best, caused many people to believe that Luigi was no longer viable.

Despite Luigi's perception, however, several Luigi mains such as {{Sm|Elegant}}, {{Sm|Navy}}, and {{Sm|Scot}} managed to produce many strong results as the metagame progressed. This, along with the several buffs he was given in his transition, helped improve Luigi's perception in the community as the buffs were far more significant than previously thought.

As offline competitive play has returned, Luigi's results have gotten much stronger, with his best player Elegant placing top 8 at several major tournaments, including a 3rd place finish at {{Trn|Mainstage 2021}}. {{Sm|Kiyarash}}, an up-and-coming Luigi main in the Wi-Fi era, has begun achieving success with the character offline as well. Thanks to his playerbase, Luigi is now mostly perceived as an upper mid tier to lower high tier character, although some players believe he should be ranked even higher.

=={{SSBU|Classic Mode}}: Luigi's Nightmares==
[[File:SSBU Congratulations Luigi.png|thumb|Luigi's congratulations screen.]]
Luigi's opponents are fighters who are creepy or scary, either because of their appearance (such as [[Dark Link]]), the series they hail from (such as [[Bayonetta]]), or both (such as [[Ridley]]). This theme is further referenced by each Round being fought on a stage that is gloomy and/or set at nighttime. The [[boss]] of Luigi's route, [[Dracula]], also fits this theme due to being a vampire and, on a related note, references Luigi's exploration of [[Dracula's Castle]] during {{SSBU|Simon}} and {{SSBU|Richter}}'s reveal trailer.

==Role in [[World of Light]]==
[[File:WoL-09Luigi.jpg|thumb|Finding Luigi in World of Light|left]]
Although Luigi does not appear in the World of Light opening cutscene, he was presumably vaporized and later imprisoned alongside the rest of the fighters (sans {{SSBU|Kirby}}) when [[Galeem]] unleashed his beams of light.

Luigi was one of the many fighters who fell under [[Dharkon]]'s control upon Galeem's first defeat, and he can be found in the [[Mysterious Dimension]], being guarded by the {{h2|List of spirits (The Legend of Zelda series)|Link (The Legend of Zelda)}} spirit after awakening {{SSBU|Meta Knight}}.

Luigi's fighter spirit can be obtained by completing {{SSBU|Classic Mode}}. It is also available periodically for purchase in the shop for 300 Gold, but only after Luigi has been unlocked. Unlocking Luigi 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. His fighter spirit has an alternate version that replaces it with his artwork in ''Ultimate''.

Additionally, Luigi makes an appearance in various primary and support spirits.

==Trivia==
[[File:Luigi double expression.jpg|thumb|Luigi's double expression glitch.]]
*Oddly, the physics of the {{iw|mariowiki|Poltergust G-00}} are different when the game speed is modified, which reduces the grab ranges of all of Luigi's grabs.
*In {{SSBU|Simon}}'s reveal trailer, Luigi was shown having his soul taken by Death, which led to humorous posts from the community claiming that Luigi had been officially "killed off". In turn, {{iw|wikipedia|BBC News}} wrote a mock [https://www.bbc.co.uk/news/newsbeat-45127783 obituary] for Luigi. Nintendo UK eventually [https://twitter.com/NintendoUKVS/status/1027210656821469184 responded] with a short message of "Luigi is okay" as a nod to this event.
**Luigi was not shown from the rest of the ''Super Smash Bros. Ultimate'' Direct (not counting menus and the like) of August 8th, 2018. Despite this, {{SSBU|Mario}} and {{SSBU|Mega Man}} were present in this Direct, even after being killed in {{SSBU|Ridley}}'s [https://www.youtube.com/watch?v=aisZuQxMZZc reveal trailer].
***Luigi is also one of three characters to not appear in any in-battle footage in the Direct, the others being {{SSBU|R.O.B.}} and the {{SSBU|Mii Fighter}}s. <!--Ryu appears in the background of the "Rules" image in that portion of the Direct.-->
*''{{s|mariowiki|Luigi's Mansion 3}}'' was teased before it was officially announced through Simon's trailer, as Luigi can be seen using the new Poltergust G-00 from the aforementioned game.
*Luigi can be seen performing Green Missile in [[:File:SSBU Panoramic.png|the panoramic artwork]] for ''Ultimate'', similar to his pose in a [[:File:SSBMCast.jpg|group artwork]] for ''Super Smash Bros. Melee''.
*Luigi is the first and only veteran in the series to have his standard grab be changed into a [[tether grab]] between installments.
*In a promo screenshot for the game depicting Luigi in his [[Waluigi]]-inspired costume, the "L" on his cap was green, but in the final game, it is purple, like in ''Super Smash Bros. 4''.
*Luigi is one of two characters to represent an upcoming game at the time of the game's release through his moveset.
**The other character with this distinction is {{SSBU|Yoshi}} through his ''{{iw|mariowiki|Yoshi's Crafted World}}'' alternate costume.
*Luigi's yellow alternate costume has a light blue L on his cap in-game, as opposed to it being yellow and matching the rest of the cap in his render.<ref>{{cite web|url=https://twitter.com/Aaronitmar/status/1074137046040616960|title=Comparison of Luigi's render and in-game model}}</ref> The head icon, however, properly colors the L.
*Prior to 3.1.0., Luigi's pipe during his on-screen appearance does not appear to have any lighting effects, unlike Mario's.
*Luigi is the only ''Super Smash Bros.'' veteran to be unlocked in the Dark Realm in Adventure Mode, and the only one to be unlocked in a sub-area.
*In the ''Super Smash Bros. Ultimate'' Direct of November 1, 2018, Sakurai noted during the part where he described {{SSBU|Ken}} that Luigi is the original Echo Fighter, as he was initially introduced as a simple palette swap of Mario in 1983's ''{{iw|supermariowiki|Mario Bros.|game}}'' with identical abilities. Likewise, Luigi was originally a full clone of Mario in ''SSB'', though he has since been heavily de-cloned to the point of becoming a pseudo-clone as of ''Ultimate''.
*Alongside {{SSBU|Greninja}} and {{SSBU|Kazuya}}, Luigi is one of three characters in ''Ultimate'' with a taunt that cannot be canceled, due to the fact that their non-cancelable taunts have hitboxes.
**Interestingly, however, it is still possible to cancel {{SSBU|Snake}}'s taunts despite them also possessing a hitbox.
*Luigi's official artwork is based on the third hit of his neutral attack, albeit featuring him with a scared expression.
*Through unlocking through versus mode and awakening all fighters in World of Light, Luigi is the last ''SSB'' veteran to be unlocked. However, via Mario's unlock tree in {{SSBU|Classic Mode}}, Luigi may be the first ''SSB'' veteran to be unlocked.
*Despite having all of his animations mirrored, Luigi has different animations when using moves that involve Poltergust G-00, so he may not face the screen when he uses his grabs and his Final Smash. He is the only character with mirrored animations to hold this distinction.
*If Luigi blocks an attack with his shield, he reverts to his shielding pose from ''SSB4''.
*If Luigi is currently under the effects of a [[Superspicy Curry]] or the [[curse]] from [[Eiha / Eigaon]], there is a glitch which results in his curry expression overlapping his angry expression if he performs either his forward aerial or charges up his Green Missile.
*If Luigi gets countered by [[Blade Counter]] while facing left, he will be forced to show his back<ref>{{cite web|url=https://twitter.com/Zeckemyro/status/1377845964216664065|title=Luigi being forced to show his back}}</ref> due to Blade Counter forcing him to use the wrong grab release animation.
*There is a minor sound effect oversight regarding Green Missile where the popping sound effect plays after Luigi has already removed his head from the wall. This is due the animation being sped up from last game without the sound effect being modified to match the animation.
