Every good hero needs an equally good rival, right?

You did mention a need for it to be scientifically sound, so that's partly why I was stuck on things. I might just go for the enhanced genius route, as that's an archetype I'm good with, and have played before. Though is there a specific character sheet template we need to have? I also need to locate a faceclaim, but I think I have one in mind, would it be fine if the super genius I use disguises themselves as another villain? Would this world have awareness of some video game villains? Because I could see them pretending to be a mad scientist from a given series, and use that to hide their true nature, and thus, make it easier to operate in public when not doing villainy?
