Dingo, If you want to make a character with a different powerset you're more than welcome to.

Abysse, You can create villain groups as long as they aren't absurdly far-reaching conspiracies like Legion. But a supervillain street gang, a group of thieves, or shady mercenary group or anything of that kind of scope and size would be perfectly fine. 

Krein, A good dark wizard always has another trick up his sleeve. Or three :P 

Pixi, No it's fine that's understandable there's no rush. I myself am about to start another semester so I will only be able to update perhaps two times a day instead of three :P
