Personally, I’m not particularly excited about either of these characters appearing in Marvel vs. Capcom 3, but hey, maybe one of you guys happens to be shit-your-pants excited about it. Tron Bonne was an antagonist in a Mega Man game who developed feelings for Mega Man (or some such crap), and X-23 is a female clone of Wolverine (this makes how many clones/derivatives of Wolverine now?).
