Powers/Abilities: Kevin Tremain possessed superhuman strength as well as incredible mathematical and analytical skill. As Post, Tremain was a unique hybrid of living tissue interconnected with machinery. As a cybernetic powerhouse he possessed body armor, a cloaking device, advanced sensor plates and bio-cybernetic weaponry, including energy blasters and power pods that fired concussive blasts. He could direct these weapons through mental commands. His sensors, some of which hovered around him, recorded and transmitted all battle data back to him, allowing him to utilize his mutant analytical talent to discern the best plan of attack and devise means to overcome mutant opponents. Onslaught also granted Post immunity against telepathy. Post could breathe underwater and was resistant to subzero temperatures. He was not fireproof.

History:

(Cable I#72 (fb) - BTS) - Kevin Tremain was a mutant who used his enhanced strength and superhuman analytical skills as a CIA operative.

(Cable I#72 (fb) ) - The CIA ordered Tremain to Northern China where he was tasked to take out the ultra-nationalist known as the Mandarin before the man's thirst for power could threaten relations between China and the United States.

(Cable I#72 (fb) - BTS) - Tremain was unaware that the Mandarin had contacts within the CIA and that the mission was designed to deliver him into the villain's hands.

(Cable I#72 (fb) ) - As soon as Tremain breached the Mandarin's compound, he realized the mission was a bust. Calling for immediate evacuation under his codename 'Groundhog', he was stunned when command denied the request. Moments later, he was overpowered by the Mandarin who plainly told him his own agency had betrayed him.

(Cable I#72 (fb) - BTS) - Tremain was subjected to torturous experiments conducted by the Mandarin's scientists who were researching ways to use his genetic material to create an invincible army of mutant clones.

(Cable I#33 (fb) - Tremain was accidentally discovered by Cable and G.W. Bridge when they attacked the Mandarin in his own complex. The villain rigged the base to self destruct, but Cable refused to leave Tremain behind. While Bridge chose to evacuate, Cable formed a psi-link with Tremain while using his telekinesis to close his wounds to keep his heart and lungs going. Once Cable had dragged Tremain to safety, he gave him a blood transfusion to stabilize him. He had no way of knowing what exposure to the techno-virus would do to Tremain (see comments).

(Cable I#72 (fb) - BTS) - Upon returning to America, Tremain was introduced to professor Charles Xavier whose teachings were a great inspiration to him. Tremain dedicated himself to Xavier's cause.

(Cable I#72 (fb) - BTS) - Onslaught mentally reached out to Post, promising the susceptible mutant a place in his new world order. Feeling the offer made sense, he decided to abandon Xavier's cause. Now a servant of Onslaught he was granted numerous gifts, including the ability to conceal himself from telepathy.

(Cable I#33 (fb) - BTS) - Cable was informed that Tremain had died (see comments).

(X-Men II#50) - Acting upon orders from Onslaught, Post abducted Cyclops, Iceman, Storm and Wolverine to submit them to a gauntlet of mental and physical tests, the results of which he instantly communicated to his master. At first, the X-Men were unable to see through his cloak, but Wolverine's keen senses eventually sussed him out. He calmly and analytically engaged the foursome, putting them through the wringer until Wolverine breached his plated armor, allowing Cyclops to hit Tremain's exposed body with a full force optic blast. The X-Men were instantly returned to the mansion where the disembodied presence of Onslaught informed them Post was merely the lowest of his emissaries (see comments).

(Cable I#31) - After remotely observing a confrontation between Cable and Earth-295's Nate Grey, Onslaught told Post these two were the greatest threats to his agenda and that he should shadow Cable. Post assured his master that his past history with Cable would not be a problem.

(Cable I#32) -  While cloaked, Post observed Cable and Domino's investigation of the Nimrod robotics facility at Camp Hayden. He watched his old friend escape the base and its defenses unharmed, reporting back to Onslaught who studied the data collected by Post.

(Cable I#32 - BTS) - Thanks to Post's observations, Onslaught concluded Cable would only be able to oppose him with the help of his mentor Blaquesmith. Onslaught instantly blew up Blaquesmith's hiding place: an old frigate in the harbor of Baltimore.

(Cable I#33) - Post waited around the Baltimore docks for Cable to arrive and investigate the destruction of Blaquesmith's frigate. He got the drop on his old ally by bursting through a pier and dragging him into the water. Cable soon realized it was Post who had been following him for days. He also figured that Post was the link between Xavier and the mysterious Onslaught. He wanted to mentally reach out and inform the X-Men but was already too weakened from the techno-organic virus running rampant through his body. Post knocked him out, though - much to Onslaught's chagrin- he refused to kill him.

(X-Factor I#125 - BTS) - Onslaught ordered Post and his recent allies Fatale and Havok to procure a small army of Sentinels stored at a Brand Corporation facility near Washington D.C.

(X-Factor I#125) - While Havok and Fatale were on the lookout, Post used his cybernetic mastery to reprogram the Sentinels. He was opposed by X-Factor's leader Forge but he proved no match for Tremain's body armor. After a brief altercation with Forge's team, Post was pleased to see the Sentinels launching to join Onslaught. Politely announcing he had grown tired of this fight, Post teleported away.

(Avengers I#402) - When Onslaught realized the Avengers had succeeded in crafting rudimentary psionic armor to defend against his power, he sent Post and Holocaust to Times Square where the heroes had gathered. While Post kept them both cloaked, Holocaust caught the team's attention by firing his cannon and hitting Thor in the back. The overwhelmed heroes had a hard time dealing with the duo until Captain America tricked Holocaust into accidentally blasting his ally. With Post down for the count, the Avengers ganged up on Holocaust who eventually went down while crowds of New Yorkers cheered Earth's mightiest on.

(X-Men II#73 - BTS) - Post joined the Brotherhood of Mutants. When they were being hunted by the sentient Cerebro, the team decided to recruit the device's creator Charles Xavier. They broke him out of Nevada's Hulkbuster base.

(Uncanny X-Men I#363 (fb) - BTS) - Post and the Brotherhood brought Xavier to their makeshift base on Alcatraz island. Though they were disappointed to learn he had lost his telepathy, they benefited greatly from his combat experience. Xavier trained the members of the Brotherhood to fight and think like X-Men.

(Uncanny X-Men I#363) - When the actual X-Men showed up on Alcatraz to look for the professor, Post and the others managed to hold their own thanks to Charles' training. Post faced Wolverine and held him off until Charles Xavier decided to show himself to explain the situation. As if on cue, they were then attacked by Cerebrite-Beta.

(X-Men II#83) - The Brotherhood and the X-Men decided to team up to defend Charles Xavier from Cerebrite Beta.

(Uncanny X-Men I#364) - Post tried to damage Cerebro with his concussive bursts, but Blob refused to get out of the way so that he could get a clear shot. When he noticed Shadowcat was trying to sneak Xavier out of harm's way, Post left the battlefield to stop her: without him, they'd have no chance of victory. Post then rejoined the fight against the Cerebrite, which ended when Wolverine severed its head. By then it was clear the Cerebrite was using its powers to kidnap mutants. Post watched the being claim Mimic, Shadowcat, Wolverine and Xavier before he was teleported away himself.

(X-Men II#84) - Post remained an incapacitated captive in Cerebro's headquarters while the X-Men went in to help Xavier and the Nannite Nina stop the threat of the sentient Cerebro.

(X-51 I#2 (fb) ) - Post was still active with the Brotherhood when they were hired by Mystique to retrieve the remains of X-51, the living robot from Area 88, a remote dump site where the government disposes top-secret materials.

(X-51 I#1) -  Post and the others ran into government agent Jack Kubrick (actually a robot) who offered his services in helping to find X-51 if Mystique promised not to kill him. While Post and the others kept the US military forces at bay, Kubrick located the head of X-51. Pleased her mission was a success, Mystique honored her agreement with Kubrick. She would not kill him, but instead she ordered Post to do it. Before the mutant could charge up his concussive pods, Kubrick placed X-51's head on his body to become a new iteration of Machine Man.

(X-51 I#2) - Post and the others tried to fight Machine Man and the military, but X-51 won the day when he used his mastery over machinery to take control of Post's weapons systems, turning the mutant against his teammates. The involuntary altercation left Post defeated and injured. He was taken away by medics.

(Cable I#72 (fb) - BTS) - Despite his injuries, Post was still strong enough to overpower the army medics that had arrived to take care of him. He fled to the Morlock tunnels where he built an effigy of of his former master Onslaught. He consigned himself to live there as the failed servant of the fallen dreamers.

(Cable I#72) - Post sent out telepathic summons to lure Cable to his location. After a lengthy conversation, including a recounting of their shared history, Cable was fed up with Tremain feeling sorry for himself and shocked some sense into him. Tremain decided to man up and take responsibility for his own actions, but refused Cable's offer to help. He quietly disappeared into the darkness.

(Uncanny X-Men I#379 (fb) - BTS) - Post reconnected with the Brotherhood of Mutants.

(Uncanny X-Men I#379) - Post and the other members of the Brotherhood were in their hideout listening to the Blob explain the details of their next scheme: steal a protoype of a new weapon built by Paradigm Micronics and sell it on the world market to the highest bidder. During the meeting, the Brotherhood began to feel the effects of the High Evolutionary decision to turn off the mutant gene. Post instantly lost his blue skin and cybernetic implants.

(Uncanny X-Men I#380 - BTS) - Following the defeat of the High Evolutionary, his mutant power dampening satellites were taken offline. As a result, all mutants on Earth, including Post, regained their powers.

(Uncanny X-Men I#388 - BTS) - Led by Mystique and joined by Sabretooth, the Brotherhood of Mutants embarked on an ambitious plan to further the mutant cause through acts of terror. While Mystique, Toad and Sabretooth tested out a new strain of the Legacy Virus, Post, Blob and others went to Washington D.C. to assassinate presidential hopeful Robert Kelly.

(Cable I#87) - Post joined the other members of the Brotherhood of Mutants in their attempt to assassinate senator Kelly. They were briefly opposed by the X-Men who quickly fell for the illusions of Lady Mastermind, allowing Post to approach Kelly without opposition. However, before he could kill the senator Post was burned to death by former Brotherhood member Pyro, himself dying from the Legacy Virus. Pyro felt mutantkind needed Kelly alive if they were to have any sort of future. He soon perished himself, but not before Kelly promised he would fight the good fight for as long as he lived.

Ah, Post... Seems like you were never designed to exist in a post 90s Marvel Universe.

You'd think that at the dawn of the internet age a cybernetic mutant with an array of floating gadgets would have been a shoe-in, but Post got the boot instead. It'd be interesting to find out why Xavier never admitted him to the school, you'd think that a former CIA operative with superhuman analytical skills would have been an invaluable asset. But ol' Post even managed to stay dead during the Krakoan era where resurrections were a dime a dozen.

It's never established how Post obtained all those sensor plates. It's implied they came from Onslaught, but it makes more sense that they're a result of the blood transfusion he got from Cable. The techno-organic virus could have just easily formed those bio-organic plates as a physical manifestation of Tremain's analytical powers.

Onslaught calling Post 'the lowest of his emissaries' in X-Men II#50 and his whole spiel about Storm, Cyclops, Iceman and Wolverine being 'the last line of defense against the coming' never went anywhere. It's no secret the X-offices were trying to figure out the mystery of Onslaught as they went along and it shows with that issue. It's a gorgeously drawn red herring that adds very little to the overall story.

Kinda like Post himself, really.
