Slaughter, formerly known as cletus kasady, was born to kill people. In his 1 1 sentence, he was released on early bail and met his new cellmate Eddie Brock. Eddie Brock, who was once possessed by a black suit (alien * * *), became a "venom". But in the battle with Spider-Man, Brock broke away from his combat suit. Now Brock can only wait for the suit to help him get out of prison. Unsurprisingly, the battle suit tried to save Brock by triggering a large-scale prison break. However, Brock didn't know that the spacesuit was pregnant. On the way out of prison, I laid eggs in my suit and stayed in prison. In prison, Casady once told Brock about his philosophy of killing: ordinary people can kill people as long as they have courage. Later, Casady inadvertently combined with the descendants of the battle suit (red battle suit), which led to the massacre.

Because the madness of the massacre is consistent with Casady's, his strength and ability far exceed Spider-Man and venom. In addition to surpassing ordinary people's strength and agility, slaughter can also be attached to the surfaces of various objects with body surfaces, and can change its shape at will, emitting reticular substances. Physical * * * bodies can also be turned into separable weapons. Although they inherit venom, their bodies are more plastic. Casady planned a successful escape, and he was determined to realize his philosophy of killing with his new strength. Then the new york Massacre started killing people for fun and was stopped by Spider-Man. However, in any case, Spider-Man could not defeat this killer 1000 times stronger than himself. Helpless, Spider-Man can only turn to the Fantastic Four who are also in new york for help. In addition, Spider-Man turned to his enemy venom for help. Venom agreed to help Spider-Man only because she didn't like her products. Facing the combination of Spider-Man, Venom and Fantastic Four, the massacre was taken to Ravenccroft Madhouse.

Later, he escaped from the madhouse by shrinking the alien (as big as his cell) and making it pass through the telephone line. When alien troops invaded the earth, slaughter fed on other aliens to increase his ability. It is disgusting that when he was captured again, his desire to kill almost reached its peak. In order to find a cure for his murderous tendency, the massacre will continue to be held in Ravenccroft mental hospital.

In addition to surpassing the power and agility of venom, slaughter can also be attached to the surface of most objects with his hands and feet, and can emit reticular substances, and the * * * creatures on his body can also be turned into separable weapons.
