Would it be possible for me to play a non-powered owl-themed vigilante or a powered owl-themed vigilante whose main or only power is an increased intellect? Or barring either of those muscle mimicry I suppose. I guess I'm asking if I can play a sort of Batman-like character, but I would take pains to establish them somewhat differently and develop them into their own character, I promise.

I'd definitely follow the suggestions for CS design though. Being a hyper-competant polymath doesn't seem as much fun as being creative with a few skills he'd be amazingly good at. I'm thinking hand-to-hand and detective skills/investigative work would be two things he would be really good at, alongside maybe some kind of technological design to explain the gadgetry?
