When Wario is "in shape", such as when he is treasure hunting as his main occupation, he is nearly invincible, but when he's not, like in WarioWare, he is sort of weak.
I've always wondered how everyone feels about a future Wario Land game. I personally don't know how I feel about the future of Wario Land, but I try to stay positive. Maybe Wario's 30th anniversary will give us something.
What's this? The Ashely in SSBU thread? What the double heck? I'm pretty sure it say Wario in SSBU. Oh well. Where there's Wario, you can usually find more Ashely than Wario.
