A biker who's farts are actually deadly.

I think Wario is tight.
Hes got that sweet Bike, an awesome Up B, a great Final Smash, and that powerful fart attack lol.

I also like his Bite attack thing. If you time it right you can pull a Kirby suicide thing with it.

Snake: This guy kind of gives me the creeps.
Colonel: That's Wario, Snake.
Wario first appeared as Mario's rival, but he really made his name in the WarioWare games.
Watch out for Wario's bite. It's not just damage you take from it.
Snake: What do you mean, Colonel?
Colonel: Wario loves garlic. He eats cloves of it day and night.
So try not to get caught in his mouth. Once that smell gets on you, it'll stick to you for quite a while.
Snake: ...that's a scary thought.
Colonel: He also attacks by farting. He can fart to fly around, too.
Snake: By farting?! Are you kidding me?!
Colonel: Sadly, no. I am not kidding. If his belly starts to bulge, watch out.
