Editing Marth (SSBU)

Anothet notable weakness is Marth's difficulty in escaping from [[juggle]]s, despite being good at juggling opponents himself; his air speed is average at best, his gravity is fairly low, his weight is slightly below-average and his tall hurtbox provides an easy target. Dolphin Slash is his only reliable combo breaker, but as it leaves him helpless, it can inadvertently put him in an even worse position. Also, while Counter can be used defensively, it leaves Marth extremely vulnerable to punishment should it whiff. Marth also has little defense against juggling, as his aerials are ineffective at relieving pressure; though his attacks have quick startup and decent range, many of them come with high ending lag, their large sourspots are fairly weak compared to most other aerials, and they also suffer from short hitbox durations. Additionally, being a solely sword-based character, Marth's [[neutral game]] suffers from his complete lack of a projectile, and he can sometimes struggle against projectile-heavy characters and playstyles; however, his combination of high mobility, good range and decent frame data helps to alleviate this issue.

However, Marth has received some noteworthy, direct nerfs, most notably to his KO ability and [[neutral attack]]. Some of Marth's sourspotted attacks (most notably forward smash and Dancing Blade's fourth forward hit) and tipper forward aerial now deal less knockback, whereas his neutral, forward and back aerials have had their hitbox positionings worsened, making landing the tippers slightly more difficult. Additionally, his up throw, previously an emergency KO option with the aid of [[rage]], is slightly weaker as well. This makes it more important for Marth to carefully space his attacks in order to land his tippers to finish strings to deal more damage and score KOs. His neutral attack, previously an excellent combo starter and neutral tool due to its first hit, has been altered as with most neutral attacks so that it can only follow up into the second hit from the first, removing its powerful [[jab cancel]] from ''SSB4'' that was useful to Marth's gameplan in exchange of more situational jab [[lock]] capabilities.

Marth's specials and grab game have also been weakened. [[Dolphin Slash]] and [[Counter]] are a bit more punishable than before, and Dancing Blade deals less damage in exchange for its improved linking potential. Aside from the nerf to his up throw, forward throw has also lost its combo potential. His less rewarding grab and larger reliance on sweetspotted attacks now weakens Marth's options against shields.

Despite benefitting from some of them, Marth has been also hindered by the gameplay mechanics, due to his defensive playstyle. Particularly, the universal increase in mobility, while improving his approach and further increasing his already fast mobility, has also made landing his tippers more difficult, as the game's faster pace fosters more aggressive playstyles than in ''SSB4''. The removal of perfect pivoting and lack of quick, safe, and reliable grounded micro spacing options further magnifies his spacing troubles. On top of it, Marth's already linear recovery was also made more telegraphed by the changes to air dodging as well as the reduction in [[edge sweet spot]] size, making him easier to edgeguard and thus worsening his survivability. Lastly, the weakening of rage weakens Marth's ability to close out stocks at ludicrously low percentages.

Overall, the buffs Marth got and the benefits he gained from the engine do not compensate the nerfs he received and the hindrances the engine has also indirectly given him, as Marth now has a harder time landing his tipper sweet spots, which is especially troublesome as he relies on spacing in order to KO opponents below high percentages. In addition, the knockback nerfs to some of his attacks have made it more difficult for him to consistently KO his opponents at low percentages. This causes Marth to shift to a more offensive playstyle, where he relies more on his sourspotted hits to combo his opponents while remaining at a safe distance from where he can poke them with tippered attacks. Game updates have remedied some of Marth's issues, making it slightly easier and more rewarding for him to land some of his tipper hitboxes and slightly improving his dash grab range, though these buffs did not raise his standing significantly. As a result, Marth performs worse in ''Ultimate'' compared to ''SSB4'', and is generally seen as inferior to his Echo Fighter and semi-clone, {{SSBU|Lucina}} and {{SSBU|Roy}}, who are widely regarded as more rewarding than him and thus superior as a result.

|nsdesc=Marth assumes a readying stance and charges Falchion at chest level before powerfully thrusting it forward. This attack deals massive [[shield damage]] even when uncharged, and will instantly break shields at full charge, although it can be safely [[perfect shield]]ed. The aerial version gives Marth a very slight horizontal boost, while a fully charged aerial version will thrust Marth in whatever direction he's facing, giving him a strong horizontal recovery option, albeit with a very high startup. Deals very high knockback when tippered, making it a powerful KOing option, (bring one of the strongest neutral specials in the game) although it is still weaker than his tippered forward smash. It can be angled up or down, though this does not change the damage or knockback. The attack deals 1.15× regular damage if it hits the opponent's head.

Subsequent patches buffed several of Marth's tipper hitboxes, making it easier to connect tippers reliably. Furthermore, since the end of the [[COVID-19 pandemic and its impact on competitive Smash|COVID-19 pandemic]], Marth's representation has steadily improved at locals and minor circuits, with success from players such as {{Sm|Kreeg}}, {{Sm|Ignaize}} and {{Sm|Rizeasu}}. Finally, MkLeo briefly brought the character back into his roster in late-2022 and early-2023, defeating players such as {{Sm|Riddles}} and {{Sm|Cosmos}}. As such, some players began arguing whether Marth was underrated in the metagame, due to the positive traits he shares with Lucina and other highly regarded sword-wielding characters, as well as the untapped potential from his tipper mechanic offering him high KO capabilities with safe disjoints. However, other players pointed to how his tipper hitboxes remained inconsistent despite the buffs and that his overall representation remained poor, often hovering around the bottom 10, with all of Marth's best players often using other characters alongside Marth. With little change in Marth's reputation in the post-online metagame, his placement has remained the same on the first two tier lists, ranking 54th on the first as a lower-mid tier character, and 55th on the second in the C+ tier.
