The Avengers of the Mutant X Universe were a more militant organization than in our reality, likely because of the poor international relations with America's neighbor, Canada, and the Cold War between the two countries when it came to Super-Soldier development and border disputes. The extent to which their history deviated from the 616-Avengers is unknown. The team appeared with a roster of Black Widow, Hawkeye, Deathlok, Typhoid Mary, and Iron Giant Man. Yellowjacket, Stingray, and the Six's Captain America were known former members.
