Years ago, U.S. government mutant operative Kevin Tremain was sent into northern China to neutralize the perceived threat posed by the Chinese ultra-nationalist the Mandarin. Betrayed by his agency, Tremain was captured by the Mandarin, who intended to use Tremain as the template for an army of mutants to conquer the Western world. Tremain was critically injured during subsequent scientific experiments before being rescued by the mutant soldier Cable and his mercenary ally G.W. Bridge. Cable infused Tremain with his blood-despite the risk of infecting Tremain with the techno-organic virus within his own system-and kept Tremain's heart pumping with his telekinetic powers so that Tremain would live long enough for Cable to take him across China to a hospital. Cable later took Tremain back to America to meet with Professor Charles Xavier, mutant telepath and founder of the X-Men, who showed Tremain the possibility, that man and mutant could coexist.
After Xavier spawned the powerful psionic creature Onslaught, Tremain was lured into his service. Onslaught used the techno-organic virus within Tremain to transform him into the cybernetic powerhouse Post.
