so I started running a generation one super hero campaign in new york, and I'm trying to fill out my rogue's gallery and I figured I'd ask you guys for ideas for villains.
the party consists of a selfish magical school girl, an alien gladiator trying to find monster island, a boy genius, his flying turtle robot butler, and a beat cop with a stone which irradiates him into a being made of void.
the villains currently consist of a cannibal hobo, another hero on the run from the law for several falsified murders, a demon lord running a law firm, and possibly a corporation beginning to dip their fingers into illegal experimental procedures.
any ideas or suggestions?
