Before the Books
As a child, Gerald, a mortal, used to go to the seaside with his mother, and was fond of hearing the tinkle of Ice Cream vans.
Before he was bitten, he was a lonely man who had no friends.
After Scapegrace became a Zombie, Gerald was his first victim. He doesn't like the name, so he gives him the name Thrasher and Thrasher becomes his second-in-command. However, Thrasher doesn't have any leadership skills, and none of the Zombies liked him. At The Midnight Hotel, he is with Scapegrace, where he suggests the name "Vengeance Brigade" instead of The Revengers' Club.
Thrasher wished he could become human again, along with Scapegrace. When Skulduggery and Valkyrie try to kill Scapegrace, Thrasher tries to protect him and Valkyrie trips him up. After agreeing for Kenspeckle Grouse to try and turn them back to human, Thrasher is happy that he is called Gerald again, but Scapegrace tells him not to get used to it. However, since Grouse is killed by a Remnant who was possessing Clarabelle, they could not return back to normal, and Caelan lets the two Zombies escape.
Thrasher first appears in the chapter in the book called "The Zombie King and Co". Scapegrace orders Thrasher to get a freezer truck though he only manages to get an ice-cream truck, they manage to drive to Doctor Nye's "lab", where they hope that it will give them what they want: Thrasher wants to be given a brain and Scapegrace wants to return to normal, they meet Clarabelle (whom they do not recognize since she has dyed her hair blue). Clarabelle tells them that she wants to go work for Nye and that he works for the Sanctuary now, they pay him a visit, unfortunately Nye does not grant the zombies' wishes but hires Clarabelle.
The two zombies retreat to the old bar Scapegrace used to own and decide to stay there for a few weeks but are soon met by Vandameer Craven, who gives them a job to steal a disc. Once they completed the mission, they are given another one to recruit twenty more zombies and to climb under Gordon's house, where the Requiem Ball would take place. However, all the zombies (not counting Scapegrace and Thrasher) are eaten by monsters. While in the tunnel, they meet Valkyrie, Melancholia, and the White Cleaver. The White Cleaver chops Scapegrace's head off, though Thrasher manages to save him. After it is revealed Scapegrace's head is still alive, Thrasher grabs Scapegrace and runs away.
Scapegrace's head is kept in a jar of fluid until he can find a new body. They make a deal with Nye to provide them with two new human bodies in exchange for the remains of The White Cleaver. Nye accidentally mixes the two brains up. Thrasher gets a very muscular man while Scapegrace is given a woman's body.
Scapegrace, still angry about the woman's body, plans to become powerful by fighting evil with the knowledge of the criminal mind. Thrasher starts to show a romantic interest in his master, to the, at first, revulsion of Scapegrace.
Thrasher and Scapegrace start to miss their old bodies, and insist Clarabelle take them to the Sanctuary where the decaying corpses are kept. After the duo find out that their bodies are used for scientific research, they take their leave, feeling slightly better.
Later, he and Scapegrace go to the Necropolis in Skulduggery's stead, and succeed in defeating the Guardian. Thrasher has a heartfelt moment with Scapegrace before he dies, but is revived after Scapegrace removes the sword lodged in his skull. He is not mentioned for the rest of the book.
Thrasher likes to protect Scapegrace, despite Scapegrace being rude to him. He has no leadership skills, cannot fight, is dim-witted and rather childish yet quite kind to those around him. However he is extremely kind and loyal to Scapegrace, despite being treated badly in return. He has a habit of annoying Scapegrace.
