Huh, interesting how someone had the idea to give Minerva's Cheetah a more, well, cheetah like design before Sharp did. And both worked with Rucka.
I remember Sharp saying it was because her curse makes her more animalistic longer she has it, but that obviously didn't keep when you look at issue #18. (Although with Infinite Frontier I guess it could be true across multiple iterations of the character/universe.)
