As Wario-Man, Wario gets massive boosts for each stat, with defence up to the point of being invincible. When a fully charged Wario Waft is used in this state, it will KO opponents at even 0% damage. However, one shouldn't use the Wario Bike as Wario will speed off at a point where he may KO himself. In Super Smash Bros. for Wii U, the Wario-Man transformation lasts much shorter than the one from Brawl.
Wario-Man is set to return to Super Smash Bros. Ultimate with a completely different attacking style. Now, Wario-Man will attack his opponent multiple times before sending them flying off stage. This was done so that the pace of the fighting is fast and straight to the point.
The Wario-Man transformation process is the same in Super Smash Bros.as it is in the WarioWare series. To transform, Wario eats a funky garlic.
