Sarge (Red vs. Blue)

Sarge is a Colonel (formerly Staff Sergeant) in the Red Army and one of the main protagonists of Red vs. Blue.

Past
Sarge was assigned to command the Red Team stationed in Blood Gulch (which was mainly comprised of himself, Simmons and Grif). Sarge's Red Team soon received two new members in the forms of new recruit Donut and robot soldier Lopez.

Eventually, Sarge and his Red Team, as well as the Blues he was supposed to be fighting against, would leave Blood Gulch and go on several adventures, including defeating The Meta and tracking down The Director of Project Freelancer.

Season 15
Following the final battle against the forces of Charon Industries, Sarge and the rest of the Blood Gulch Crew (Grif, Simmons, Tucker, Caboose, Washington and Carolina) went into retirement on a remote planet. However, Sarge began to lament that he had not died gloriously in battle like he had wished.

After the Reds and Blues encountered the Blues & Reds, Sarge chose to defect over to them and assist them in their war against the UNSC, even after learning of their true plans, as it gave him the chance to die in battle like he had always wanted. However, Simmons, Donut and Lopez (as well as Caboose and Tucker) refused to join the Blues & Reds after realizing they were "evil", forcing Sarge to turn on his men.

Sarge and Surge cornered the Reds and Blues in a room, but they were unable to stop them from launching Lopez's head into space via rocket to find help.
