An American "super-soldier", who is just a normal GI with a uniform that resembles the costume of Citizen V from Earth-616, rallies his men in the face of a Japanese attack.

Later, a teenaged Erik Lehnsherr visits the Weapon X complex and sets Wolverine free, letting the captive Canadian soldier know that his name is James.

They discuss the theories involved with having "mutanity" accepted and eventually relocate to the Savage Land, where Magneto's Brotherhood is waiting to be trained by the two.

General Ross feverishly questions him about his previous involvement with the mutant known as Weapon X and the nature of Nick Fury's unique physiology.
