Frank DuFresne

Medical Officer Frank "Doc" DuFresne is a Main Character in Red vs Blue, First Appearing in episode 20.

Arrival
He was sent by Blue Command to treat Tex, three months too late. He was sent over to the Red Team as a 'hostage' following a firefight that took place almost immediately after his arrival. He was actually on loan to both armies due to lack of resources, and therefore, not a real hostage. He draws the ire of both teams by being a pacifist (annoying the Blues) and running Sarge over with the Warthog (which was actually being remotely controlled by an unknowing Church.) He was eventually cast out to live in the caves when the Blues refused to take him back from the Reds.

Infection by O'Malley
Rejected by both armies, he is left in the middle of Blood Gulch caves. During most of Season 2 he is forgotten about by both teams and is infected by O'Malley. This happens after Tucker successfully gets the Reds to shut off their radios (after having Lopez sing in Spanish over the radio) and after Church and Tex eject O'Malley from Caboose's mind. He finds a Strange Vehicle in the caves and (under the control of O'Malley) attacks everyone during the "Triangle of Confusion". He kidnaps Lopez and goes through the teleporter. He's next seen on Sidewinder where he fights the combined Red & Blue teams. He is blasted into the future when the bomb goes off and takes-up residence in Zanzibar with Lopez. The Red Zealot finds them and they exploit him to guard the fortress. He didn't fight when Tex, Tucker, Caboose and The Reds attacked the fortress, though he and Lopez retreated to the beach and Lopez made his Robot Army. When the Robot Army is done they attack, Donut steals The Motorcycle and an Alien destroys the army. Later he moved into another fortress and was called back to Blood Gulch to see what was wrong with Tucker. He arrived and diagnosed Tucker with pregnancy.

Taking Care of Junior
After his arrival back on Blood Gulch, Doc became no longer infected by O'Malley. He managed to deliver Junior, Tucker's kid, and was given the job of watching Junior while Tucker was in a coma. After Tucker woke up he was still Junior's babysitter. When Sheila was acting strange Church sent Doc over to check on her. Also when Sister arrived he gave her a physical. He seemed to have become a member of the Blue Team though still pointed out that he was stil "technically neutral". Later in Reconstruction he was called to heal Caboose but when he got there everyone had already left.

Rank
Doc claims he pestered command for so long that they gave him the rank Medical Super Private 1st Class. He uses this to his advantage by ordering Church to leave Tucker and his kid alone.
