Wario-Man (ワリオマン, Warioman) is Wario's Final Smash which has him transform into Wario-Man, his costumed alter-ego from WarioWare: Twisted! and WarioWare: Touched!, by eating bad garlic. In Brawl and SSB4, Wario-Man can be freely controlled, moving and attacking normally with a moveset similar to Wario's. In Ultimate, the player initiates a rush forward, which can trap opponents and trigger a single flurry of blows with comical effects before the Final Smash ends.
In Brawl and Smash 4
In Brawl and Smash 4, Wario takes a bite of garlic and turns into Wario-Man while laughing. The transformation is somewhat similar to Bowser's. During the final smash, all of his moves are upgraded greatly, being extremely fast and strong and have decreased ending lag. All of his throws are able to KO opponents above 70%. Wario-Man's attacks deal more damage and knockback, and he's virtually invincible, which even includes being immune to footstool jumps. However, he can still be affected by random tripping (in Brawl only), take damage by eating explosive items or going off-screen, and be affected by size changing items, such as the Super Mushroom and Poison Mushroom. Also, Wario-Man is unaffected by Metal Boxes.
Wario-Man's mobility is also increased greatly, enabling him to run just as fast as Sonic the Hedgehog, and he has the highest air speed of any fighter in Super Smash Bros. Brawl. In Super Smash Bros. 4, Wario-Man's mobility remains mostly unchanged, but his status as the fighter with the fastest air speed is given to Giga Mac instead.
All of Wario-Man's aerial attacks, except his down aerial, cause him to gain altitude without entering helpless mode, giving him unlimited recovery. This also means that Wario-Man can easily perform both Hyrule Jumps. However, since his aerials make him gain altitude in a set path, an effective wall of pain is not possible. All of his aerials can be strung together for a rather ridiculous-looking upward movement.
Wario Waft charges faster, and a fully charged Wario Waft from Wario-Man can deal one-hit KOs under normal circumstances, though the half charge one is unaffected. His bike becomes so fast that it can outrun the cars in Big Blue, and must be jumped off almost immediately to avoid self destructing on smaller stages. Additionally, Wario's Corkscrew deals electrokinetic damage to any fighter it hits.
Once the duration of the Final Smash is up, Wario-Man will spin in place while surrounded by a ball of light, causing him to revert back to Wario. Immediately after transforming back, Wario will perform an animation, during which he is briefly intangible. On the ground, Wario will get up and brush dirt off himself, and in the air Wario will spin in place while posing with his mouth open. In Brawl, Wario will make a loud, echoing "Oooooh..." right after transforming back, while he stays silent in Smash 4.
It is interesting to note that Wario-Man's moves that normally can only be used once can be used again when he transforms back into Wario. For example, if Wario-Man does a Corkscrew and then transforms back into Wario in mid-air, it's possible to Corkscrew a second time without touching the ground. Also, if Wario-Man transforms back into Wario while wielding a Hammer or a Golden Hammer, the Hammer will restart its process over again, allowing the player to double the amount of time they can use the hammer. Occasionally, because the process restarts itself, the player may end up getting a headless hammer or a squeaky Golden Hammer afterwards.
The transformation lasts for 16 seconds in Brawl and 12 seconds in SSB4.
In Ultimate, the move has Wario charge forward after eating the garlic. If the rush connects, he turns into Wario-Man and unleashes a barrage of attacks accompanied by comical text and effects, ending with a fart that launches the trapped opponents. The Ultimate version of Wario-Man joins all former "transformed moveset" Final Smashes (such as Giga Bowser and Giga Mac) in losing its player-controlled moveset in favor of a quick attack that returns players more promptly to normal gameplay.
Wario-Man originates from WarioWare: Twisted! and WarioWare: Touched!, appearing as the alter-ego for Wario. In both games, once the player has beaten all of the microgame compilations from the other characters, the player unlocks Wario-Man's microgame compilation. In WarioWare: Twisted, Wario transforms into Wario-Man after falling into Dr. Crygor's invention: the Gravitator while in WarioWare: Touched! Wario transforms after consuming a rotten piece of garlic. This "new character" then appears on the main menu with a brand new set of microgames available to attempt. Wario-Man's games were the last of its kind both times and were more challenging than the preceding games.
In the cutscenes before and after his microgames, Wario-Man exhibits some kind of superhuman abilities; however, his increases in speed, strength and the capability of flight in Smash is more likely derived from typical superhero/super-villain powers in general comic books and other media.
Changes from Wario in Brawl
Besides a few very minor nerfs, Wario-Man outclasses Wario in every single regard and is considered one of the best final smashes in Brawl.
Changes from Brawl to Smash 4

In Super Smash Bros. Brawl
With just a little nibble of garlic, humble everyman Wario transforms into the hero of justice, Wario-Man! He's...still not really all that strong, but he does get quite a bit faster, and he can launch foes farther too. And like any good hero, he has the ability to fly...by spamming attacks in midair. Just like they all do it, right?
