[@FantasyChic] Well that's what the bump was for. Trying to get this thing started. Yeah, it's similar to Alphas and Heroes even in that respect. There are no "supervillians", more just people who use their powers to get what they want.

You can do either. If a character already exists with the power you had in mind then you can use them if you desire. However is entirely up to you. If you do pick a power, ensure it is entirely unique to that character as that is one of the rules of this Universe.
