Grimjack is the main character of a comic book originally published by First Comics. John Ostrander and Timothy Truman are credited as co-creators of the character, although Ostrander had been developing Grimjack with artist Lenin Delsol before Truman's arrival on the project. According to Ostrander's own text piece in Grimjack #75; in that same essay, the writer also revealed having initially conceived the character to be the star of a series of prose stories, set in a post-apocalyptic Chicago.

Grimjack is the street name of John Gaunt, a sword-for-hire, ex-paramilitary, war veteran and ex-child gladiator. He operates from Munden's Bar in the Pit, a slum area of Cynosure, a pan-dimensional city to which all dimensions connect.

John Gaunt, alias Grimjack, was born in The Pit, a slum area of the pan-dimensional city of Cynosure, where both magic and technology, humans and aliens intermingle. His mother, Anya (née Laughton) died in childbirth. John had two older brothers, Nick (nicknamed "Young Nick" and named after their father, "Old Nick") and Jake. His father married Anya's sister, Maite (nicknamed "Mouse") and they had one child together, Joe. Joe was the only of his brothers for whom John cared, and he vowed to Mouse that he would watch out for him. Old Nick had one brother, Jack. Young Nick hated and resented John, blaming him for the death of their mother, the only person who loved him. Throughout John's life, Young Nick manipulated their father into hating John in hopes that he would kill John.

When John was about five years old, Old Nick attacked and killed Jack in a drunken rage. He was sentenced to prison but later escaped. The day he returned home Mouse vanished. It is unknown whether Old Nick killed her. On John's eighth birthday, Old Nick, having decided that Gaunt was actually Jack's son, attacked John with a broken bottle. This caused the distinctive vertical scar that Gaunt carried through his life. Old Nick fell in the fireplace and burned to death
