Super Smash Bros. for Nintendo 3DS/Wario

Treasure hunter and microgame master Wario is back in action! Wario's playstyle certainly defies his appearance. While he looks like a clumsy heavyweight, Wario is actually a surprisingly agile air-based fighter. With extremely quick air attacks and great aerial mobility, Wario can weave around above his opponents like an obese ballerina, and he has a variety of recovery options to boot. Wario not just hovers like a butterfly, he stings like a bee as well, with powerful KO moves and an array of tricky special moves that will keep enemies on their toes. However, having stubby limbs gives Wario some significant range issues, and he often has trouble approaching characters with greater reach. While there are definitely no lack of aerial fighters in the game, Wario's properties and moveset make him one of the more interesting characters of the category.

Basic attributes
As one might expect, Wario is a heavyweight, although he leans closer to characters like Samus and Link than to Donkey Kong and Charizard. His ground speed is pretty average, nothing to write home about. However, his aerial stats are where he shines. Wario has excellent lateral air speed, falling just behind Jigglypuff, and has moderate fall speed instead of being exceedingly floaty. Lastly, Wario is one of the few characters in the game with a crawl, although it's functionally useless as the height reduction is negligible.

Final Smash - Wario-Man
Wario chomps down on some garlic and temporarily becomes Wario-Man! In his superhero persona, Wario is a much stronger fighter, gaining invulnerability and enhanced moves. All of his attacks are generally faster and stronger, and Wario can spam them in quick succession. Most of his air attacks let him gain height when used, letting him stay in the air indefinitely, while Down Air causes him to dive downward. His Corkscrew has a lot more height and his Bike is dangerously fast. Finally, an uncharged Wario Waft can now dizzy enemies and a fully-charged waft is a guaranteed KO. Wario-Man is one of the best transformation Final Smashes in the game, as you have excellent mobility and total invincibility. Go on a full offensive while you are transformed, since your opponents will not be able to retaliate due to your invulnerability. Pound on them with lightning-fast moves and finish them off with powered-up smashes. Wario-Man has many odd momentum shifts on his moves that make him weird to control, but it makes him even deadlier once you can utilize them properly in aerial chains.
