History YMMV / SuperSmashBrosUltimate

** Back in January 2019, ''Ultimate'''s first DLC character had a lot of people scratching their heads and asking "Why Piranha Plant?" Flash forward four years and now there's Piranha Plants aplenty in ''VideoGame/SuperMarioBrosWonder'', a bold new title that shakes up the 2D Mario formula in a fair few ways. Suddenly, its inclusion doesn't seem as odd...[[UnexpectedCharacter still odd,]] but not as much.

* HilariousInHindsight: The memes that spawned from Kirby’s copy ability from inhaling [[VideoGame/Persona5 Joker]] giving him a gun got even funnier after ''VideoGame/KirbyAndTheForgottenLand'' introduced Ranger as a copy ability, and it’s one of the best in the game at that.

** Byleth's stoic behavior when beating up opponents have earned them this reputation in some parts of the fanbase, but especially with their down special, in which they swing a large axe down that could break shields with ease, more so on [[https://knowyourmeme.com/photos/1724677-super-smash-brothers-ultimate someone like Pichu]]. This becomes HilariousInHindsight as ''VideoGame/FireEmblemWarriorsThreeHopes'' shows that's canonically how they appeared before becoming a professor. Presumably, the turned based combat just made it easy to forget that they're actually really creepy in a fight due to their condition.

** Hearing "VICTORY!" after defeating a difficult spirit, like a Legend-class one or some Ace-class spirits, even more so if done on the first try.

** In ''Melee'', people complained about Young Link for being just [[ExactlyWhatItSaysOnTheTin "Link, but younger"]]. Now people are excited to play as him again as the other two Links in the game have changed quite the amount since ''Brawl'', and he himself is the only way to play as the Hero of Time in this game.

** Some fans of the ''Franchise/ShinMegamiTensei'' series weren't happy to find that with Joker's pack the series received no acknowledgement at all, with no songs or anything that originated outside of ''Persona''. Since the series has been on Nintendo hardware for years and was even referenced by Sakurai and Nintendo at the time, this felt like a snub, even more so considering that Atlus' own push of ''Persona'' as their golden goose and the resulting neglect they've shown to other members of the ''Megami Tensei'' family (including the main parent series itself) remains a contentious issue in their fanbase.

** [[VideoGame/MonsterHunter Rathalos]] is widely considered among the hardest boss battles, and in World of Light, he's even more so than the bosses that come later in the Dark Realm, most notably [[BreatherBoss Marx]]. The issue with Rathalos is that you might not have powerful Spirits coming up to his battle, and his attacks, compared to fellow Light Realm bosses [[BreatherBoss Galleom]] and [[GoddamnedBoss Giga Bowser]], [[LightningBruiser are faster and deal high knockback right off the bat]]. Unlike other bosses in the mode, he can also render himself unable to be damaged, as he either fires explosive fireballs that expand like a Smart Bomb, or swoops from the background to deal high damage and knockback. He can also feint some of his attacks and fly upwards, causing you to miss on precious damage if you were planning on punishing him with a move as he was coming at you. Speaking of his flight phase, his most reviled attacks consist of firing three consecutive fireballs that cause big damage and chain into the others as long as the first or second one hit, and a slashing swoop attack that causes DamageOverTime to your character, as if they had a flower but without the ability to get rid of its effect. Overall, do not expect Rathalos to fight fair. To rub more salt in the wound, you have to fight Rathalos ''before'' fighting the real final stages on Bowser or Hero's Classic Mode paths, meaning he can put an end to your run early.

** This was likely a major factor in why Byleth got a mixed reception when revealed as a DLC character. They ended up as the last character of Fighters Pass Volume 1, coming after the [[UnexpectedCharacter unexpected]] Joker and Terry, the long-awaited Banjo & Kazooie, and a fighter of one of the most important RPG series in history with Hero, leaving many fans underwhelmed that the last character was such a "safe" option.

** Due to the return of Pokémon Trainer, some fans of [[SuperMode Mega Charizard X]] disliked how it was completely removed as Charizard's Final Smash to make room for [[CombinedEnergyAttack Triple Finish]]. These fans attest that having Charizard Mega Evolve during Triple Finish would have been perfectly fine and wouldn't have come across as pandering or favoritism,[[note]]given that Squirtle and Ivysaur have the excuse that they ''cannot'' Mega Evolve since they haven't yet reached their final stages,[[/note]] and that its removal makes for a much more "generic" and "cheesy" Final Smash for the Trainer. Even most fanmade fighter concepts for other Trainers that use a Triple Finish-esque Final Smash have their ace Pokémon Mega Evolve if able (such as [[VideoGame/PokemonDiamondAndPearl Cynthia with Garchomp]]), demonstrating widespread acceptance of the idea. This slowly died out as the ''Pokémon'' franchise started moving away from Mega Evolution as a selling point and removing it from its mainline games, but many fans attest that not using it in this specific case stands out regardless, given that Mewtwo and Lucario continue to do so and that Greninja uses its similar Ash-Greninja transformation.

** A more subdued case here: the Mii Fighter costumes have been much better received compared to their debut in ''For 3DS/Wii U''. Where before, many players seemed to see them as an insult, the inclusion of some rather surprising picks like [[VideoGame/{{Undertale}} Sans]], VideoGame/{{Cuphead}} and [[VideoGame/{{Fallout}} Vault Boy]] have excited the fanbase almost as much as if they had been actual fighters, to the point that many fans are now ''hoping'' that certain characters, especially those who may not make good ''Smash'' fighters, can get a second chance as costumes. King K. Rool and Chrom getting promoted from Costume to Fighter in ''Ultimate'' probably helps too. That being said, they're still rather contested, if not more than ever, given that they include other fan-favorite requests like [[VideoGame/XenobladeChronicles2 Rex]] (although this was alleviated somewhat with Pyra and Mythra's playability and the fact that Rex was still considered to appear as a playable fighter for the second Fighters Pass), [[VideoGame/SuperMarioRPG Geno]], [[VideoGame/TalesOfSymphonia Lloyd Irving]] (both returning from ''Smash 4''),[[VideoGame/NoMoreHeroes Travis Touchdown]], [[VideoGame/DevilMayCry Dante]], and VideoGame/{{Shantae}} (all of which were heavily requested to be playable by fans).

** While ''VideoGame/{{Yakuza}}'' fans latched on to Kazuya's white and red suit alt for resembling Kiryu's own suit, Kazuya previously donned a similarly colored suit in ''Tekken 5: Dark Resurrection'', where everyone who was already in the original ''VideoGame/Tekken5'' got their default colors changed.

** Some people have accused Ganondorf's new Smash attacks of being blatant pandering to all the "Canondorf" fans. What makes this more noticeable is how it's his ''Ocarina Of Time'' incarnation who uses the sword, which was never in the game itself, and the animations look very similar to Ike's and Cloud's smash attacks. However, this is generally considered a minority opinion, as Ganondorf's moveset has long been criticised for being TheArtifact and a poor representation of the character.

* FanPreferredCouple: In the advent of her Palutena's Guidance being rewritten to accommodate her [[{{Moe}} new redesign]], ''many'' fans took to shipping Pit x Zelda, due to how much Pit [[CannotSpitItOut fawns over]] Zelda's new appearance, complete with Viridi using Pit's new crush on Zelda to repeatedly [[LoveMakesYouDumb make a fool out of him]].

* EvilIsSexy:
** Marth's puppet fighter (who showed up for a few seconds in Hero's reveal trailer) has been getting this reaction from fans.
** While previous ''Smash'' villains have been popular in the {{Bara}} and [[PopularWithFurries furry]] communities, Sephiroth is unabashedly a MrFanservice who is admired for his beautiful looks both in- and out-of-universe.

*** ''VideoGame/{{Metroid}}'' and ''VideoGame/{{Castlevania}}''[='=]s newcomers are loved because of how well they represent their franchises, both of which are more popular on the other side of the Pacific.

** Strangely enough, [[MovesetClone Echo Fighters]]. While "clone" characters in ''Smash'' were seen as contentious due to many people accusing them as being a "waste of a character slot" that could've been reserved for whatever new character the fandom mob wants to promote, rebranding them as Echo Fighters managed to help turn favor around towards them, being seen more as a creative way to add characters that might be too similar or niche from an already represented series. While some people were hoping more Echo Fighters to be added to the game, there were only five Echo Fighters added to the game on release, and none for the [=DLCs=].

** Not much of the Inklings themselves, but the colors of their ink. The default orange ink color has for some reason been given a light-reddish tiny, and the other colors aren't much better. The yellow and lime-green colors are a much duller and more muted shade, contrasting the vivid look they had in the ''Splatoon'' series.

YMMV tropes with their own pages:

** To a lesser extent, the infamous "Smash Bros. is for good boys and girls" line from the Direct presentation on Terry. What was thought to be Sakurai throwing shade at Mai fans was actually the result of a mistranslation of what he was ''actually'' saying, which was that ''Smash'' was rated as a game for kids. Sakurai would later express irritation with said translation, saying it was essentially having words put in his mouth.

** Simon is commonly depicted committing or planning to commit VanHelsingHateCrimes against fellow fighters who are or at least vaguely resemble GothicHorror creatures, such as mistaking Inkling[[note]]Due to their CuteLittleFangs[[/note]], Corrin[[note]]Due to their draconic wings resembling that of a bat's[[/note]], and Wii Fit Trainer[[note]]Due to their literal pale white skin, not unlike a vampire[[/note]] for [[OurVampiresAreDifferent vampires]], having Bayonetta or Ashley [[BurnTheWitch burnt at the stake]], mistaking any of the ''VideoGame/StarFox'' and ''VideoGame/AnimalCrossing''[[note]]Excluding Villager, of course[[/note]] characters, as well as some of the more "anthropomorphic" Franchise/{{Pokemon}} (like Lucario and Incineroar), for [[OurWerebeastsAreDifferent werebeasts]], and Kazuya for being a literal [[DemonOfHumanOrigin demon]]. A similarly common follow-up on this is Richter being the OnlySaneMan to his ancestor, often portrayed as being infinitely more understanding (due to Richter's starring roles involving him teaming up with Maria Renard, his sorcery-using cousin, and Alucard, {{Dracula}}'s {{dhampyr}} son).

* PopularWithFurries: Largely due to this game adding the most anthropomorphic animal/bestial characters than any game that came before it. This includes newcomers [[note]]Ridley, King K. Rool, Isabelle, Incineroar, and Banjo & Kazooie[[/note]], as well as returning ones[[note]]Bowser, the ''Star Fox'' fighters, the returning ''Pokémon'', and Sonic[[/note]] and even some Assist Trophies[[note]]The ''Sonic'' assists, [[VideoGame/DillonsRollingWestern Dillon]], and especially Krystal, due to wearing her [[{{Stripperiffic}} outfit from]] ''VideoGame/StarFoxAdventures'' and her... [[GoingCommando exposed private parts]][[/note]].

** [[MovesetClone Echo Fighters]] in general got a huge boost in popularity after the E3 2018 Direct made it more clear to the players that they are supposed to be bonus characters rather than "roster padding" as they've been seen as in previous games, simply by making their character number the same as their base characters' numbers, but with an epsilon symbol added (which implies that they officially aren't seen as characters made from scratch). This spawned tons of fan demand to see characters such as [[VideoGame/EarthboundBeginnings Ninten,]] [[VideoGame/StreetFighter Ken Masters,]] and [[Franchise/SonicTheHedgehog Shadow the Hedgehog]] be playable (which turned true in Ken's case). It's been helped by the fact that Echo Fighters can be "stacked" on top of who they're a clone of, making them feel more like alternate costumes with differing properties.

Sakurai would later express irritation with what was essentially having words put in his mouth.

** While fans were appreciative that Hero had alternate costumes representing several games in the ''Dragon Quest'' series, many were left questioning the use of Solo over Sofia to represent ''Dragon Quest IV'': while both are considered to be the same character, Sofia represents the first female protagonist in the series (the female version of Erdrick being added to later versions of ''Dragon Quest III'') and has a sizeable fanbase who prefer her to Solo. Not only that, ''none'' of the female protagonists appear in the Hero's final smash either, despite ''Dragon Quest IX and ''Dragon Quest X'' also featuring them as options.

* OneSceneWonder: [[VideoGame/KirbySuperStar Marx]] has proven especially memorable despite his [[GiantSpaceFleaFromNowhere lack of plot relevance]], thanks to SurpriseCreepy and BodyHorror. Many encountering this boss for the first time rank him as the freakiest thing in ''Ultimate''.
