Frank "Doc" DuFresne

Frank "Doc" DuFresne is one of the main characters from the Red vs Blue web animation.

Doc is sent to the backwater outpost to aid both teams. Doc, who earns his nickname after Church declares DuFresne too hard to pronounce, hardly deserves his title. He attended (but did not pass) medical school at Jamaica State, doesn't know how his healing doodad works, got his unique rank by sending Command a letter every day for four years asking for it, and treats Caboose's foot injury by rubbing his neck with aloe vera. Doc's pacifism, political correctness, and incompetence quickly make him unwelcome in either base, leaving him to wander the gulch, forgotten until Caboose's "exorcism" leaves the AI O'Malley without a host. The Omega is able to possess him completely, leaving Doc a passenger within his own skull, only able to talk or shout apologies for O'Malley's actions. O'Malley eventually comes to regret choosing Doc as a host, as the two end up having Gollum/Sméagol style arguments over whether or not to kill people, if their nefarious secret lair needs an answering machine, etc. When Doc is called back to Blood Gulch to deal with Tucker's "illness," O'Malley jumps ship, freeing Doc once and for all.

His whereabouts during Reconstruction are unknown, though when Washington asks the Reds if they know a medic, they violently answer in the negative. In the extended version, they do call him, but forget (or didn't care enough) to tell him they didn't need him anymore. He arrives to find no one there, and says to no one in particular: "You guys suck."

In Revelation, he is called to Valhalla by Simmons, who was coerced into calling him by Wash and the Meta. He becomes a hostage of Washington, but due to the Stockholm Syndrome, they develop a bit of a rapport. He denies this strongly, however. Doc stays behind at the farm in Valhalla with Donut.

When notified that the Reds and Blues are stuck on Chorus, Doc flies there with Donut and Lopez. He begins assisting the Red team before he is hit by one of Grif's teleportation cubes, and doesn't reappear when the cube is thrown again. Excluding Lopez, nobody seems to notice his disappearance. He is later found hiding out in one of the caves on Chorus after getting sent to an alternate dimension.

In the XP4 fics, Doc is part of the Dimensional Defense Union and is a member of the Omega Squadron.

Appearance
Doc is wearing a purple-colored body armor over a black armored bodysuit. His armor consists of helmet with an orange visor that covers his entire head, a chest & back armor, a back & front cod piece, shoulder armor, forearm armor, hand plate, armored thighs, armored shins and armored boots.

Personality
Doc is one of the calmest and least aggressive characters in the series. Many of Doc's actions do not benefit him in any way, suggesting that Doc is very selfless and kind. However, several situations have shown that Doc is quite cunning and wise, as he is able to get what he wants and comes up with ideas that could have benefited Washington when he was with them. Doc is also shown to be very timid and easily scared, such as being possessed by O'Malley, abused by the teams, and frightened to attack the Meta. Yet, after Omega left him, Doc becomes more assertive and self-confident, improving his character possibly because of the A.I. Though he has been abandoned, Doc has always returned to help those he knows, showing that he is a loyal and trusting person.

The ordeal he endured after being accidentally teleported in Season 11 is shown to have impacted his sanity, as he says in Temple of the Key that he "lost his mind, found it, and then lost it again." Following his return, Doc's realization of how little his friends actually valued him has resulted in a facsimile of the O'Malley personality surfacing, born out of Doc's own subconscious as opposed to A.I. implementation. Similar to Omega, the seemingly natural O'Malley personality does not overtake Doc's, but instead, much like before, engages in banter with him. Despite the continuous claims of villainy and tyranny, however, Doc continues to act as an ally to the Blood Gulch Troopers while acting under the O'Malley personality.

However, in True Colors, he betrays the Reds and Blues and joins the Blues and Reds because of all the abuse and indifference he suffered since he met the Reds and Blues. Although, in Blue vs Blue, Doc rejoins the Reds and Blues after failing to talk the Blues and Reds out of their plan for revenge. Doc is plagued with guilt, wanting nothing but to redeem himself, though the Reds and Blues treat him worse for his betrayal. Doc reveals that he became a medic to atone for his failure to save his younger brother, leaving him a rather tragic character. Ultimately, Doc's regrets allows his O’Malley personality to dominate again. It was until season 17 that was able to comeback merged his to personalities together.

Medication
Originally, Doc was shown to be a bad medic. For example: he gave Caboose a massage when he was shot in the foot, he failed medical school, and is unaware of the symptoms for certain illnesses. However, near the end of Season 4, his skills in medicine greatly improved; he was able to deliver Junior successfully, treat Capt. Flowers after Omega left him, treat the Meta when he came to Valhalla, and saved Donut from bleeding to death after a gun shot. He also helps Washington recover from his battle with the Meta.

Combat
Due to being a pacifist, Doc avoids conflicts as much as possible and isn't skilled in many weapons. However, when affected by O'Malley, he was shown to be quite skilled with the rocket launcher, such as when he took on both the Reds and the Blues at Sidewinder alone. Though he no longer has Omega, he has become more aggressive and willing to join in fights than he originally was. After developing a split personality with traits of Omega in Season 13, Doc is shown to harness this other personality in order to become more combatative. In Armonia, Part 1, Doc manages to kill three space pirates with a Rocket Launcher.

Agility
Doc is capable of running faster than most other soldiers. This skill is first seen when Doc, possessed by O'Malley, attacked the Reds and Blues in K.I.T. B.F.F. where he escaped both teams line of sight, kidnapped Lopez as a hostage and ran to the top of the base all in what seemed like an instance. Later this was shown again in Reunion, where Doc saved Washington's life by quickly going to the Warthog to throw its tow hook towards him. During the episode, Doc stated he couldn't throw very well because running was what he excels at and has stated in previous episodes that he got the ability to run fast because he "lettered in track in high school", and added that the reason he took track was because "it was the least directly competitive sport [he] could find."

Cleverness
Though he isn't one of the most intelligent characters in the series, Doc is very clever. During Season 5, Doc was able to convince Command to not only promote him, but give him his own rank. In addition, Doc was also sly enough to get what he wanted every time, such as pulling ranks on Church to save Junior's life, having Caboose donate his blood to Junior, and getting to see Sister naked (something Tucker couldn't do). In Revelation, while Wash and Meta were tracking down the Reds and Blues, Doc had several suggestions that could have aided the ex-Freelancers that even Washington didn't consider, saw through Tex's trap and saved Wash from falling to his death using the warthog's tow hook. Doc, under O'Malley's influence, also manages to convince Grif to give him the time machine in A Pizza the Action.

Trivia

 * Doc is the only character shown on the Season 2 DVD box art, with his back to the camera, making him the first character from the series to appear on a season DVD box art.
 * Ever since O'Malley left him, Doc has become more aggressive despite being a pacifist, such as back talking to both Caboose and Sister in Season 5, saying, "Fuck you guys" to Sarge, Grif, and Caboose in a Recreation deleted scene, using a Missile Pod in New Digs despite being a pacifist, calling his attackers "jerks" in Drink Your Ovaltine, and after firing at the Meta in Recovering One, Doc insults him continuously.  Later in Standardized Testing, he says watching the Meta eat somebody would be "kind of interesting," and in Reckless, Doc wanted to join the Reds and Blues in a rescue mission. After his long absence throughout the Chorus Trilogy, he outright tackles Tucker and starts beating him up in Temple of the Key.
 * Doc is the only neutral character from the Blood Gulch Chronicles and the Recollections to appear in both the Halo 3 and Halo 4 engine.
 * In Halo 2, Doc's emblem is a medicine pill.
 * Doc was called and appeared in Reconstruction: Chapter 12 sponsor cut to help heal Caboose, but the group had already left by the time he got there.
 * Although it was confirmed at Comic-Con 2010 that Doc would return in Season 9, he did not appear in an episode.  However, technically, he did appear in the Season 9 PSA Drafted, along with O'Malley.
 * According to comments made in Episode 26, Doc failed out of medical school, reinforcing him as the least qualified medical officer in the series.
 * Doc is a vegetarian, as stated in Episode 36.
 * Despite claiming to not be experiencing any signs of Stockholm syndrome, Doc does try to bond with Washington several times and even saves his life while he was held captive.
 * Though Doc is neutral in the Red vs. Blue war, he spends most of his time with the Blues in The Blood Gulch Chronicles.  However, in later seasons, he spends more time with the Reds than the Blues.
 * Doc often seems to end up with the antagonists of the series. He was under the control of Omega for a very long time in The Blood Gulch Chronicles and was held hostage by Washington and the Meta for most of Revelation. In Season 15, Doc purposefully allies himself with the Blues and Reds, marking the first time he has willingly joined the antagonists. In The Shisno Paradox, Doc joined the Agents of Chrovos, though this was due to the time travel corrupting him and causing his O'Malley split personality to become dominant.
 * Doc's rank could be considered similar to one of Grif's old ranks, as they are both not real in military, both are "first class", and both obtained them from Freelancer Command (Grif got his from Washington specifically, while Command got him his to get him to shut up; similarly, it is likely neither of these are their official ranks).
 * Doc claims that he gets paid overtime, much to Washington's surprise, due to the fact that Freelancers don't.
 * In a deleted scene on the Season 10 DVD, Doc was left behind at Valhalla while the others went to rescue Epsilon and Carolina. Doc, armed with a rocket launcher, walks outside and notices that the others have gone. A UNSC trooper then approaches Doc and asks him if he has three extra planes that he and his comrades can borrow before cursing at the teams.
 * Despite not being an official member of the Reds and Blues, Doc's often considered as one of them, such as by Felix in FAQ.
 * In Lost But Not Forgotten, a female medic of the New Republic is shown and has purple trim unlike others Rebels, similar to Doc who has purple armor.
 * Doc shares a few similarities with Dr. Grey, as both utilize questionable medical practices, have the color purple with their armor and are completely insane.
 * Doc technically appears in Season 12, through a PSA. Although, he is possessed by Omega, so Doc himself does not make a proper appearance, only his body.
 * In the RvB Holiday Special (non canon) Sarge says that "Doc keeps talking about something called Kwanzaa..." suggesting that Doc may be African American.
 * The Fan Guide also states that he "began his career by failing out of the homeopathic medicine program at Jamaica State". Assuming he is from Jamaica, this would also support his ethnicity being Black.
 * He has offered numerous questionable treatments including
 * Rubbing aloe on the neck if shot in the foot
 * using orange juice to fix a shot leg
 * He described his kill count as "very high", and once mentioned that he killed a huge number of people during his residency on operating tables.
 * By his own admission in The End, Doc has developed a fear of heights due to the Reds and Blues' reckless piloting of a damaged Falcon. Sarge and the Meta also share this fear; all three characters are coincidentally voiced by Matt Hullum.
