I think the problem is that regeneration, invulnerability et all kind of offset any downsides the adoptive muscle memory would have, and kind of make it completely cheesy. ^^; It doesn't really matter that the RP isn't about fighting, it's still kind of... I mean I know a couple of people who've been put off joining because of that power, or that combination of powers at least. It dissuades people from joining with physical abilities (even mundane ones gained through training), and in the case a fight [i]does[/i] break out (which... Has a strong possibility of happening, it's a superpower RP after all), it kind of guarantees an instant victory for her. Sorry about this, but... I just think that maybe you should drop one of them? Any one of the powers she has would be quite formidable on their own, honestly. Combining them all seems a bit unnecessary and kind of... Yeah.

And comparing her to a Kryptonian doesn't help, honestly.
