My concept is going to actually be Kirby, from the Kirby's Dreamland games. My idea was that it would actually be Kirby, transported through a warp gate from Pop Star to the "real world". He's a hero because he's well used to fighting evil, but he's having to deal with both the attention from his odd appearance, having to learn the language, and the fact that in the real world, people look down on someone sucking an enemy into the pocket dimension inside their stomach and swallowing them to steal their abilities... considering that when Kirby does that in most of his games (Super Smash Bros. exempt), the enemies vanish, never to reappear again, so who knows WHERE they go. :P
I'm 100% new to the system, so both builds and explanations of why you would chose one option over another would be appreciated.
