VIA BARON: The Nazi team is pretty badass. And who doesn't love Nazis? The team would be dedicated to Red Skull's plans of world domination and overall badlyness. Holocaust and Kroenen work. Metallo as a hired gun/muscle would be a nice fit there. Nimrod could be shown that Red Skull's plans would prove the downfall of mutant-kind. There may be some uneasiness between Nimrod and Holocaust though. Grendel is the key here. If he's down to go along, then this team is friggin solid. If he has a change of heart half way through, the ensuing battle between Grendel and Kroenen would be pretty epic (so overused these days, but I feels it fits with this fight).
