My primary power would be that when I touched anybody I would instantly know everything they know. Secondary power would be indestructible bubbles I can control with my mind.
My weakness is falling. I have to be in the act of falling for it to apply, and it is very hard for someone to make me fall because I can use my bubbles to make myself fly, though not very fast. Not so much as a weakness than a inconvenience, but when i use my primary power too much my head starts to hurt.
My name would be Omni since it is like a short version of omniscient.
My costume would be a cloak so I don't touch someone unless I mean to.
My character does not like using her powers a lot, so she only occasionally turns evil. Plus she has no offensive powers, so she can't exactly go on a rampage.
I would be like 8 so I'd be pretty young for an epic.
Edit: It's not like I'm immune to my powers or even know what the darkness is, but I don't like using them because the more info I get the bigger the headache gets. Just to be clear.
