He is Unus, the Untouchable! One of the X-Men's oldest foes, Unus was an early recruit to the Brotherhood of Evil Mutants who remained comfortably in the role of follower and enforcer. His force field is both defensive and offensive, able to actively repel anything that tries to get too close. A career criminal, his habits occasionally brought him into conflict with other non-mutant crime-fighters. Perhaps what Unus is most known for is his force field growing beyond his control, forcing away food, air, even the ground beneath his feet. He's actually died on more than one occasion because of this complication.

The Crimson Commando, Stonewall and Super Sabre were a trio of mutants who expanded the roster of the Brotherhood once they became Freedom Force, creating tension between the "evil mutants" and these (relatively) good-intentioned World War II veterans. As X-Men supporting characters, though, they received little development after their introduction, and Stonewall and Super Sabre did not survive the Freedom Force era. After suffering severe injuries in their final mission, the Commando was rebuilt into a cyborg (because it was the 90's). He only made a few more appearances, culminating in a story from a series of pack-in mini-comics from a Marvel / Hardee's restaurant fun meal! collaboration. Fifteen years later, he reappeared only to die in a one-off story. Despite the opportunity offered by Krakoa for these men to return, young and vital, for now it seems their chances at resurrection have passed them by.
