Duggan's run on UA ended with #23, a generally popular book with x fans, however going forward Deadpool and Cable are likely to be be gone. Leaving the X-presence to Rogue and kinda/sorta/not really Quicksilver.
So who should be the X representative to fill the void?
My thoughts...
1) Beast: If any character screamed, "I need healing!" it's Beast. If the new UA squad has Wonder Man as is expected, Beast might actually re-capture something of when he was a fun and likable character!
2) Multiple Man: Anything to bring a character back to life, am I right? But still Jamie's got a lot to offer to a team. He's worked for the government before, Avengers is a little more clean than that.
3: Adult Ice-Man: Hey if you're serious about this push, why not a team too? Honestly for a guy who's ventured outside X-men before, how has this guy not been an Avenger before?
