New team:
KA-ZAR (KEVIN PLUNDER)
Talk about an outcast. Hailing from a world in which the entire Earth is a Savage Land, Ka-Zar is going to have the most trouble acclimating to his new life as an Exile. Ripped from his wife, child and tribe, thrown into worlds of technological wonder, this man would end up exemplifying badassery. While he's sociable enough to get along with his teammates, he's still coming from a different moral environment. The fit will survive.
THE CAPTAIN (LEMAR HOSKINS)
Similar to our world's Hoskins, this man once played the Bucky to John Walker's Captain America. Unwilling to retake his title, Rogers remained Nomad and Walker eventually died during a mission. Feeling it was his right to take up the mantle, Hoskins became the Captain, a decision that quickly brought him into conflict with the government, who had already lined up their own successor. Compared to any other Captain America the team may know and will meet, Hoskins is brash and unexperienced, but that is sure to change with time.
MS. FANTASTIC (VALERIA RICHARDS
Valeria Richards, smartest woman on the planet. Smarter than her father Reed, smarther than her godfather Victor, she does justice to the title of 'supergenius'. And that's it. That's her superpower. Just one big honkin' brain. While well-trained, this generally means she needs to steer clear from the up close and personal action: Ka-Zar and the Captain do most of the hand-to-hand combat. But don't tell her she can't do something because, well, she'll do it.
NOVA (KO-REL
I was sad to see Ko-Rel bite the dust, so she'd get another chance on the Exiles team. She doesn't really need much of a change from her 616 person besides being dead, so just to note: gets along well with Ka-Zar, although not always fond of his macho awys. Doesn't get along so well with Valeria, since she can be quite snooty. Ko-Rel is also a rather disciplined woman, coming from a tough past, whereas Valeria has had it pretty easy since, well, she was born - except the birth itself, of course.
GHOST
Every Exiles team has to have a villain-that-is-a-hero-in-a-different-reality, so here's the Ghost. His motivations are not that different: he hates corporations and thus likes tearing them down. In the 616 his methods are villainous, but when you come from a world where Obediah Stane is President of the United States? That just might skew the perspective somewhat. His teammates will school him in how to behave when The Man isn't the target.
SPIDER-GIRL (ANYA CORAZON)
Finally to round out the team is Spider-Girl. As an apprentice to her world's Sorceress Supreme, she provides the mystical element. But she's still also quite young and inexperienced. But she'd definitely grow out to be the heart and soul of the team over time, with a youthful exuberance the others lack.
