C'MON MAMOMMMAX. If he wasn't already in X-Force I'd say those gloves were Black Tom Cassidy.
I hope the other two are Neal and Monet.
This looking more and more like a new Fallen Angels team.
Well, Sabretooth is locked in the bowels of Krakoa so its obviously not him.
i can say this. the team is geared towards functionality. and that makes sense given Sinister's presence. he's a practical goal driven individual. Scalphunter is there because of his reputation as a tracker. he is skilled at hunting mutants. that's the same with Nanny and her muscle the Orphan Maker. Alex is there for leadership ability (or as an unwitting pawn of Sinister). this leads me to believe that the last two were chosen because their individual skill sets matter to the mission. i buy that it's Empath in the front. he would be quite useful in the field, if their mission is to retrieve mutants who might be reluctant or are being guarded by uncooperative people. and the clawed individual is likely a tracker. it's not Wolfsbane. and there's no outline of a tail.
not so obvious when you take into account that Mister Sinister is a completely amoral individual with goals of his own. for him, Sabretooth being in the bowels of Krakoa is just potential leverage for someone like Sinister. this group might be operating without Krakoa's permission/knowledge.
