The Freak first appeared as a background character in Spawn #33, in which he saved the Violator from drowning. After running away, he later reappeared, apparently being attacked by a gang of thugs. Spawn rescues him and is later convinced by The Freak to help him kill Dr DeLorean and avenge the death of his family. After doing this for him it is discovered that The Freak is in fact insane and that Spawn has been tricked into murdering The Freak's own therapist. The Freak reappears again later with a gang of street thugs who manage to overpower and apparently kill Spawn when they capture him in the Deadzone. The necroplasm he saves from Spawn's crucified body would later cause a murdered bum, Eddie Beckett, to be reborn as The Heap. Spawn's body is retrieved from the Deadzone by Detective Sam Burke and Detective Twitch Williams, which allows Spawn to return to life thanks to bugs and insects in the alley.
The Freak is killed when Spawn suffocates him with insects that were created when Spawn took The Freak's inner evils and gave them tangible form. Seeking to return to their place of origin they attempt to reenter The Freak, but in doing so suffocate him.
The Freak reappears in Hell in Spawn #100, laughing madly as Spawn confronts Malebolgia. Later, when Spawn and Cogliostro are drawn into Hell along with the Redeemer, the Freak is seen wandering through a frozen wasteland of Hell, before finally locating a mysterious box that had been given to Cogliostro by Mammon. Freak is later found by Redeemer, staring at the contents of the box, and begs Redeemer to take it from him. He describes the unseen contents as both beautiful and terrible.
