I don't want to be rude or come off as judgmental, but I've been in a bunch of RP's with superpowered characters before and I've kinda grown tired of purely combat-focused characters. I don't enjoy being in RP's where it feels like my character has to "compete" to be viable, i.e. if they don't have a power that's as devastatingly effective as the others they don't have much of an effect in the plot. I'm not questioning your judgment as GM, but personally, I'm leery of some of the character's very broad skill sets, incredibly formidable powers, and very few weaknesses that actually seem like a hindrance. I'm sure this'll be a great RP, I just think it may not be for me. I feel like I'd need to make an insanely powerful character just to be relevant and I'd rather not do that.
