Cleavon Twain and his older brother grew up on a chicken farm in Louisiana. There, Cleavon had a pet dog that repeatedly tried to bite his brother. This led him to warn Cleavon that he would kill the dog if he attacks him one more time. Eventually the dog bit his brother and was subsequently killed by him. Cleavon was heart broken, but still looked up to his brother. The brothers later joined the a biker gang called the 'Headhunters'. Cleavon states that his brother was the 'badass' of the gang. The Twain brothers had since grown estranged, with Cleavon descending deeper into a life of crime, while his brother returned to life on the farm. Eventually, Cleavon Twain made his way to New York, where he was tracked down by the Green Goblin and given advanced technology, including a high-tech adamantiumvibro-axe that could cut through anything and a hover platform for transportation. He also had a strength boosting harness that made his axe swings even more powerful and deadly. He was sent to help the Enforcers escape from Spider-Man, which he accomplished by forcing Spider-Man to flee. Harry Osborn alerted Spider-Man to the criminals' meeting place, and the Headsman was forced to flee after the ensuing battle after Spider-Man damaged his power pack. After repairing his pack, Headsman teamed with Lucky Lobo to kill Spider-Man. Believing he had killed Spider-Man, he left the hero buried under a pile of rubble. Facing Spider-Man again, he was assaulted by the Green Goblin, who revealed himself to Headsman as his employer. The Green Goblin destroyed the Headsman's equipment and knocked him out, allowing Spider-Man to turn him over to the police.
Many years later, the Headsman joined Osborn's Thunderbolts black ops team. He helped discredit Doc Samson by attacking Air Force One disguised as the Green Goblin. Osborn saved the President in a staged attack by tossing the faux "Green Goblin" from the plane. The team's next objective was to kill Deadpool, at which they failed miserably. His teammate the Ghost revealed to him that the gravity-grip he used on his first mission was faulty and that he had fixed it, suggesting that Osborn had meant for him to die in his fall from the plane. He battled new teammate Mister X, but was spared from death by the Black Widow. When the Thunderbolts capture Songbird and Natasha Romanov, they are ordered to execute them. However, the consciences of Headsman, Ghost and Paladin get the better of them; they allow the prisoners to escape, knocking out their teammates and erasing their memories of the event.
Death
The Uranian of the Agents of Atlas later implants a suggestion in the mind ofScourge to execute Osborn when he next sees him; after the mission, a hologram of Obsorn appears before the Thunderbolts, which triggers Scourge to shoot, but the bullet passes through the hologram and hits Headsman in the head. Following the Siege of Asgard, his brother was given his high-tech axe by Ant-Man.
Powers and abilities
The Headsman wears a power pack which enhances his strength. He wields a high-tech adamantium vibro-axe and has a disc-shaped hovercraft for personal transportation. Even without these devices, he possess exceptional strength and endurance for a normal human, and has incredible skill with an axe.
