Editing Luigi (SSBU)

|ranking = 47

Luigi is ranked 47th out of 82 on the current [[tier list]], placing him at the end of B+ tier. This is a noticeable drop from his 18th out of 54 placement in ''SSB4''. Similarly to [[Mario (SSBU)|his brother]], Luigi has excellent frame data, with low [[startup]] and [[ending lag]] on the majority of his kit, making him a very difficult character to punish. His outstanding air game is augmented by his strong aerials having fast startup, low ending lag (except neutral and back aerials) and landing lag, and lenient [[auto-cancel]] windows, with all of them being able to auto-cancel from a short hop. Additionally, Luigi boasts incredible combo ability and KO power: his [[down throw]] is one of the best combo starters in the game, and allows him to either perform consistent [[zero-to-death]] combos on the vast majority of the roster or set up for a kill via [[Super Jump Punch]], [[Luigi Cyclone]], or a sweetspotted back aerial at high percentages. Finally, Luigi Cyclone's frame 1 [[invincibility]] when used in the air gives Luigi a reliable combo breaker.

However, Luigi is still plagued with heavily exploitable drawbacks that he had in previous games. His overall mobility is sluggish, with his [[air speed]] being one of the slowest in the game. Luigi's pitifully slow air speed is an especially painful hindrance, as it makes him susceptible to [[juggling]]. Along with his slow ground movement, his ground game is also further brought down by his below average range, which makes it difficult for him to fight against [[camping]]. Lastly, Luigi's recovery is very predictable and linear, as Green Missile only grants Luigi horizontal distance with noticeable end lag, while Super Jump Punch only travels straight upwards with no horizontal gain. Finally, Luigi Cyclone lost almost all of its utility as a recovery and gimping tool, as it no longer grants Luigi any vertical or horizontal distance for recovery, nor can it gimp opponents offstage. Additionally Luigi's disadvantage state is also poor due to his low air mobility and his limited options to escape juggles, while he can use Luigi Cyclone to potentially escape combos and juggles, it can be fairly predictable and the opponent can easily punish Luigi due to the move's high ending lag.

Overall, Luigi is a character who, in the right situation, can setups for quick and unexpected KOs, but on the other hand his weaknesses can allow opponents to take advantage of his poor mobility and predictable recovery. This has allowed him to foster a good-sized playerbase spearheaded by players such as {{Sm|Luugi}} and, prior to his ban, {{Sm|Elegant}}.

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 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 a few 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 installments.

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 as well as functioning as an effective [[out of shield]] option, and down smash is very useful for punishing rolls thanks to its minimal lag, respectable damage output, and long range, with its back hit being an especially good finisher. Both up smash and down smash also have set-up potential at low percentages if Luigi successfully covers the opponent's options afterward.

Despite his extremely poor air speed, Luigi has a fantastic set of aerial attacks, courtesy of them possessing 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 of his aerials with a short hop, can auto-cancel all of them except neutral aerial 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 the only [[sex kick]] that consistently launches an opponent vertically, which grants it a few notable perks: the clean hitbox deals high damage and respectable knockback, making it a great combo breaker and even a situational KO option while near the upper [[blast line]] at high percentages, while both it and especially the late hitbox are very useful combo starters when used with a [[short hop]]. Forward aerial has the lowest ending lag of its kind and launches at the [[Sakurai angle]]; at low to medium percentages, these traits make it very reliable for [[approach]]ing, 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 him 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 option 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 beginning at 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 use [[directional influence]] to survive it. 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 a pair of 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 undulates; these traits make it somewhat less effective at hindering an opponent's [[recovery]] attempt, but allow it to cover a consistent area horizontally and vertically. Compared to Mario's version, Luigi's Fireballs have less ending lag as well as a clean hit that deals more damage, allowing him to throw another one just 1 frame before the clean hitbox ceases. Luigi's [[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 and landing lag and its sourspot being mostly useless aside from being a niche gimping option.

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 and edgeguarding. 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, but unlike Mario, he can have a tendency to run hot and cold. His extremely fast frame data, devastating combos and strong air game and grab game collectively make him a force to be reckoned with, so long as his opponents make careless mistakes. Luigi's overall combo game, KO potential, and advantage state are easily superior to his brother'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 special and up special 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 mix-ups and powerful combo game is crucial to achieving success with him.

However, Luigi has also received several buffs, with said buffs being of greater quantity than his nerfs. 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, as [[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 more effective at KOing due to its much faster and farther release making it harder to DI.

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 and gimping potential being removed: in addition to its aforementioned higher knockback, it inflicts more damage, pulls opponents in more consistently thanks to its new windboxes, connects more reliably, has increased range, and grants [[invincibility]] on startup; in particular, the lattermost change means Luigi has the fastest option to break out of combos in the game.

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.

**It can also be used a [[grab aerial]] but not as a [[tether recovery]].  

|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.

|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°.

|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]].

|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.

|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.

|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}}.

|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. Notably, the projectile will still be launched if Luigi inputs grab in the air but lands before before the projectile is launched. 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.

|pummelname=Poltergust Shock ({{ja|オバキュームショック|Obakyūmu Shokku}}

|pummeldesc=Vacuums the opponent with the Poltergust G-00. It is much quicker, yet much less damaging than Luigi's previous pummel.

|ssdesc=Crouches and then propels himself forward to perform a flying [[Wikipedia:Professional wrestling attacks|battering ram]]. It takes 1.5 seconds 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.

|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.

*{{Sm|Elegant|USA}} - The best Luigi player of all-time, notably placing 3rd at {{Trn|Mainstage 2021}} and 4th at {{Trn|Riptide}} and {{Trn|Low Tide City 2021}}. His highest ranking was 14th on the [[OrionRank Ultimate: Eclipse]], the highest-ranking Luigi player on a notable global ranking. However, he has since been banned in several regions as a result of controversial actions while drunk.

*{{Sm|Kiyarash|USA}} - Gained notoriety during the online metagame and was the best Luigi in the United States's online metagame, with notable placements such as 2nd at the {{Trn|SWT: NA Southwest Ultimate Online Qualifier}}. Although he has yet to attend much offline, he has seen some solid results, including 6th at the {{Trn|SWT: NA West Ultimate Regional Finals}} and 17th at the supermajor {{Trn|Crown the Third}}.

*{{Sm|Lunamado|Japan}} - Plays a multitude of characters, including Luigi, and has placed top 8 at several Sumabatos with Luigi, including 1st at {{Trn|Sumabato SP 16}}.

*{{Sm|Luugi|UK}} - The best Luigi player in the world following Elegant's ban and the second Luigi to be ranked top 50 on a notable global ranking, ranking 47th on the [[LumiRank Mid-Year 2023]]. His 2nd-place finish at {{Trn|King Of Fields 95 3}} marks the highest placement for a Luigi player at a major.

*{{Sm|WaKa|Mexico}} - The best Luigi player in North America following Elegant's ban, and one of the best players in Mexico. Although his activity has been either online or in-region, he has won many regionals in his region and has also placed highly at all Mexican majors he attended, including 9th at {{Trn|Smash Factor 9}} and 17th at both {{Trn|Smash Factor X}} and {{Trn|Delfino Maza 2023}}. He is also ranked 66th on the [[UltRank 2022]].

*{{Sm|Yamanaction|Japan}} - The best Luigi player in Japan. His upset over {{Sm|ProtoBanham}} at {{Trn|Umebura SP 7}} is the largest upset at an ''Ultimate'' major, with an upset factor of 14. He has also placed highly at several majors, including 9th at {{Trn|Kagaribi 7}}, and was ranked 90th on the [[OrionRank 2022]]. However since 2023 he has been placing more focus towards {{SSBU|Steve}}.

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 his results being mediocre at best at the time, 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 numerous buffs he gained the transition to ''Ultimate'', 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 improved significantly; his best player, Elegant, achieved top 8 placements at several major tournaments, including a 3rd place finish at {{Trn|Mainstage 2021}}. {{Sm|Kiyarash}}, an up-and-coming Luigi main during the Wi-Fi era, has also managed to achieve success with Luigi offline. Thanks to his playerbase, Luigi is now perceived primarily as an upper mid tier to lower high tier character, currently ranking at 47th, although some players believe he should be ranked even higher.

Luigi's opponents are fighters who demonstrate a creepy or scary motif, 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; by extension, his role as the boss also references Luigi's exploration of [[Dracula's Castle|his castle]] during {{SSBU|Simon}} and {{SSBU|Richter}}'s reveal trailer.
