A mutant who was the one who tried to assassinate Robert Kelly for the second time.
kevin tremain was a mutant captured and studied by the mandarin. On a secret mission, the six pack attacked the secret base tremain was held in. Kevin was mortally injured and cable tried to keep him alive by first using his telekinesis to keep his body together then by giving him a blood transfusion. Although it seems he survived this trauma, cable seemed to think Tremain had later died.

years later tremain resurfaced as post as one of onslaught's men but as one of the lowest of his men. Onslaught forced gateway to teleport cyclops,iceman,storm and wolverine to an area so that post could "test" them. The four managed to defeat post and were transported back to the mansion. Later, post attacked cable, who instantly recognized his identity as tremain. Post defeated cable and left him for the hulk. Post was later charged with ensuring the sentinels would launch, and battled x-force and succeded in protecting the sentinels, but onslaught and post were later defeated.

post was one of the mutants who attacked robert kelly but was killed by his fellow mutant pyro who saved kelly from post. Pyro then died of the legacy virus but only after he asked kelly to give up his mutant hating agenda.
