Unbeknown to Adam-X, Strong Industries was, in actuality, funded by Project: Wideawake to develop a means to exterminate the “X” gene that makes mutants.

Although initially meeting as adversaries, Adam-X and X-Force eventually join together to combat Martin Strong, once they discover that he is a mutant himself.

Adam-X and Shatterstar, in particular, discover a mutual affinity due to their alien mutant status and love of battle.

Adam-X uses his mutant power to “heat” Summers' blood and keep him warm until he finally manages to carry him to a hospital.

Adam-X meets Captain Marvel, and the two encounter the Shi’ar agent, Davan Shakari (aka Erik the Red).
