Thrasher's real name was Gilbert Sagarra and he was a tall and a powerful man with a height of 6'6. He was part of the team along with Snake Vargas, Angela Deth and Hell Razor that invaded Base Cochise but was severely wounded in the fight and lost his leg, leaving him unable to participate in field operations.

After being injured in the fight to take down Base Cochise, Thrasher became a cartographer for the Desert Rangers. He is still able to walk since a doctor named Kyle provided him with an advanced prosthetic leg, powered by a fuel cell implanted in his chest.
He is typically found in the Ranger Citadel, near the museum, where he takes care of the many maps in the Ranger archives (and complains whenever the always warring Rail Nomads force him to update them).
