According to OP:
Gameplay from cota she however, has some moves that didn't appear in the original game. An Electric Shield that makes her invincible and a one-hit kill super based of her UMVC3 super. Like Cyclops, her voice is from the X-Men anime

Warning: If the mention of a one-hit kill wasn't enough, she is busted. Not recommended for balanced rosters But fun to mess around with casually TBH
