I wouldn't worry about it; like I've said, every character will suffer some fitting limitations, so take what the sheets say with a grain of salt. Terra will find herself quite a bit more 'Vincible here lol.
From the ones you've said here, I'd only really advocate against Diavolo since King Crimson is both crazy strong and quite aggravating for most people to wrap their heads around. Kira'd be fine, as long as it's him before Bites The Dust, because that really complicates things with him.
Bruno's just cool though, got no beef with STICKY FINGERS!
Regardless, glad to see more folk getting on the hype train here! Once I can settle on which villain I plan to use as my primary choice (beyond ones I'll be running as GM from time to time), the opening post should happen, so look forward to it guys! :D
