I'm always inspired to try to build clix forces base on oddball comic lineups, here is a force inspired by the reported new lineup of the Thunderbolts:

85 AV Luke Cage
79 FF V Songbird
77 FF E Mach-3
76 HoT Moonstone
47 AV Crossbones
36 Sin V Ghost

= 400 points. If you want 14 points in feats, drop to the Rookie Ghost.

There is some wiggle room on the FF pieces, but I think the ones I chose are actually the best for the points.
