Good stuff A3n.
I don't know that she would be human, as she absorbed the power of a Moonstone that she doesn't have any longer, so that would make her mutate.
For her personality, I can't think of the term off-hand, but she likes to play mind games and has messed with her teammates on the Thunderbolts.
I guess that at some point, Moonstone can be done as well since that's Karla's most iconic character, as Meteorite was just a brief period relative to her history. Probably the same stuff but change out Negotiation and give her something more sinister than Protector. Wow, that's usually seems to have been DC only type thing, though usually DC has 6 people playing the same character.
