This version of Martin Stein was created by Eobard Thawne's use of the Spear of Destiny. In Doomworld, Martin is an overworked scientist abused by both Thawne and Jefferson. He was forced to create a thermal reactor by Thawne, in hopes of destroying the Spear so no one could undo Doomworld. When Jax tried to restore his memory with Palmer's reality gun, Martin destroyed it, believing Jax was trying to kill him. After Thawne destroyed the spear, Martin was free to go, claiming he never wanted to see Jax again.
