It'd be really cool if it had a hidden ability or something that weren't levitate. Electric/Flying is a pretty good type combination. I like the design of the fan form more than the others, for the most part.
I remember thinking it was pretty annoying back when I occasionally battled online during gen 5 (like half of all teams led with it lol). As a Pokémon though, I think it has a pretty good design, although I like Poliwrath more.
