Powers and Abilities

Slayback is a well-trained, unhinged Department K assassin whose body has been colonized by techno-organic circuitry, reanimating him as a sort of undead cyborg. While he remains in charge of his thoughts and body, it is now superhumanly strong, tough, fast and durable.

His main asset are his arms — they can extend or retract at lightning speeds, and he can grow/extend his hands enough to hold a person in one hand. As long as his opponents are within range, it makes thrusting his suddenly gigantic hand forward and grabbing his opponents quite easy, even against extremely agile targets.

His stretching arms and usually huge and clawed hands, moving at extraordinary speeds, also make it very difficult to actually hit him in melee, if only because getting close enough is quite a feat. It usually takes Wolverine-like prowess, speed and ferocity to successfully engage Slayback in melee.

His tissues (hardware ?) are also flexible, self-repairing and reconfigurable to some extend, for instance to grow claws or to turn his hands into a sinister, jagged pike or drill.


Terraerton, from Melbourne, was part of a secondary project associated with the complex Department K military-industrial world — a Canadian-hosted but NATO-funded project in superhuman killers and soldiers.

He’s known to have operated as part of a team comprising Deadpool, Sluggo, Garrison Kane and Copycat, but there is no evidence he was related to either the “Roman Numeral Weapons” projects (starting with Project:Rebirth, aka Weapon I, which eventually created Captain America) or the best-known project among those, the tenth one — Weapon X.

He likely was superpowered while an employee of Department K, but the details are unknown — though it is possible he received a small quantity of techno-organic circuitry, making him a symbiotic cyborg. The team was apparently fairly successful, and Slayback mentioned that, at this point, he had money, a family and a comfortable home.

Slayback was apparently a savage, psychotic killer reveling in unnecessary slaughter — and it got so bad that, at one point, Deadpool murdered him to make him stop. Although the merc-with-a-mouth did a particularly thorough job to make sure Terraerton could not survive, it failed. It took ten years, but techno-organic circuits grew within his body until they reanimated him. Granted a new life, Terraerton dedicated himself to taking the most painful revenge he could think of on the elusive Deadpool.

He got his wish fairly soon, as Deadpool and other members of their old Department K unit got involved into the fracas surrounding the will of the deceased crime lord Tolliver, who apparently owned some form of ultimate weapon. Most members of the old unit converged on the hiding place of the weapon at roughly the same time, leading to a clash between Slayback, Deadpool, Copycat and Garrison Kane — the latter two eventually siding with Deadpool.

During the fray Slayback accidentally impaled Copycat, who was trying to protect Deadpool. Although this shocked him since he liked her, he got over it within seconds.

Slayback was defeated when Weasel, Deadpool’s associate, activate Tolliver’s ultimate weapon — an ADAM android from the far future, programmed to destroy any weapon and enforce peace. Slayback was apparently dusted, Kane had many of his bionic parts neutralized, but Deadpool managed to convince the ADAM unit to leave him alone so he could use his healing factor to save Copycat’s life.

Despite his apparent destruction, a seemingly unfazed Slayback eventually came back and allied himself with a small cabal who had come up with a plan to use the Weapon X healing factor as a base for a cure for the deadly Legacy Virus – since such a drug would be worth hundreds of millions. Slayback heard about them and naturally offered his services, insisting that the first subject to be captured should be Deadpool. He got his wish and they managed to locate and nab Deadpool.

They then moved on to another subject Maverick (who did not have the full healing factor, being just blessed with the anti-aging sequence — but had the “advantage” of being infected with the Legacy Virus), but Slayback was less enthusiastic about grabbing Maverick than Deadpool and Maverick got away. Slayback consoled himself by torturing Deadpool.

Hearing about Deadpool’s disappearance, Maverick deduced what was going on and enlisted the help of another Weapon X vet, Wolverine, to rescue Deadpool. Using Maverick’s extensive connections, they located and assaulted the prison lab, freeing Deadpool but clashing with Slayback. Slayback was surprised by Wolverine’s ferocity but started getting an upper hand until Maverick nailed him from behind with copious gunfire. This stunned Slayback long enough for him to be caught in the self-destruction of the lab.

Though Slayback has not been seen since, it is highly improbable he was actually slain by the blast.


See illustration.


Slayback is a savage, manic killer who has lost everything and is consumed by hatred toward Deadpool — and he was a bloodthirsty psychopath even before *that*. He speaks with a British accent and diction — and occasionally overdoes it for humour value. His speech is usually composed of death threats.


“ I never had a problem with you, Garrison, so don’t give me cause to have one now. It has taken me almost ten years to return from the dead. And having returned, I find I only want one thing out of this new life I have been granted… I want to see Deadpool DEAD !! And I want to make sure it is SLAYBACK who KILLS him !”

“Hello, lil‘ chippie —long time no see — top o’ the day t‘you.”

“Shhshs. Not a peep Vanessa, m’dear girl. Looks like the last peg has come to fit in the round hole.”

“Scared of me just a wee bit, aren’tcha, lad ? That’s good, Wadie — y’should be. Y’should be properly scared of any man who comes back ten years after he died, ten times angrier, for one reason and one reason only — to rip you apart PIECE by bloody PIECE !”
