Red Vs. Blue.

Luithin_ Full Name: Dexter Grif {Grif}
Armor Color: Orange
Signature Weapon(s): The Meta's Brute Shot (Renamed "The Grif Shot"), Battle Rifle, Teleportation Grenades (Renamed "Future Cubes"),
Side: Red, Chorus
Info: Grif first appeared at the start of Episode 1, along with Simmons. Grif was forced into the Red army after the first military draft in hundreds of years. He is incredibly lazy and a loudmouth, often talking back to Sarge. Grif is shown to be relatively adept at driving vehicles, even managing to fly a Pelican and a Hornet with next to no experience with aircraft. He is also shown to be exceptionally hard to kill, being able to survive multiple shots, being run over by a tank, and falling from extreme heights. He has a mostly begrudging kinship with his teammates, and is slow to assist them, but will assist them nonetheless.
In Reconstruction it is revealed that he was promoted to the rank of Sergeant when Sarge refused relocation, but is later demoted to the fictitious rank of "Minor Junior Private Negative First Class" because of a deal between Sarge and Agent Washington. It is eventually revealed that Grif does not avoid work or ignore orders out of sheer laziness, but as a way of showing disrespect towards Sarge, whom he dislikes. This bears out Church's assessment of Red team in the early seasons, judging Grif to be the most overall competent member, and the biggest threat, assuming he ever developed the motivation to use it.

Luithin_ Full Name: Michael J. Caboose {Caboose}
Armor Color: Blue
Signature Weapon(s): MA5D Assault Rifle
Side: Blue, Chorus
Info: Caboose first appears in Episode 3 of Season 1 as a new recruit for the Blue Team. According to the backstory released by Rooster Teeth, Caboose is the youngest in a large family. He apparently joined the Blue Army by mistake; he thought he was signing up for a study abroad program in France. Caboose is from the Moon (Southern Colony #6) and is portrayed as one of the more eccentric characters in the series.
Ever since Reconstruction, Caboose wears a Mark V Mjolnir helmet, instead of Mark VI.
Consistently shown to be mentally abnormal, his behavior varies from merely somewhat dim-witted in Season 1 to almost completely divorced from reality from Season 3 onward. This is most likely due to Omega ('O'Malley') possessing him in Season 1 and permanently damaging his mental faculties after he left. It is stated that Tucker and Church once "rebooted" his armor, causing his life support systems to shut down - including his oxygen supply. It is implied that Caboose suffered brain damage from oxygen deprivation.
His unusual behavior frequently earns him scorn and disrespect from the other characters. It is a running gag that he either injures or kills anyone that he attempts to help, to the point where Command has a keyboard shortcut to report his team kills. In the original series, he killed Alpha-Church with the Blue Team's tank, Sheila. In Reconstruction, Washington finds him in a military stockade, apparently for accidentally killing several squad-mates. Later in Reconstruction, in an attempt to stop Agent South, Church tells Caboose to "help her", resulting in Caboose immediately shooting her. In the first few series Caboose falls in love with Sheila the tank, but loses her when Lopez comes into the picture. Despite his shortcomings, he is arguably the most genuinely loyal character and frequently displays above-average physical strength, which Church and Tucker describe as "God's way of compensating". In Reconstruction, he has an uncharacteristically smart idea to get into Freelancer Command by using captured Freelancer vehicles, stating "they can't see inside of a tank". He is also able to gain better fighting prowess than a Freelancer by focusing his rage. After this alternate personality is uncovered, Caboose speaks in a deep baritone.

Luithin_ {Locus}
Full Name: Samuel Ortez
Codename: Locus
Appearance: Steel with Sage trim
Signature Weapon(s): Sniper Rifle, Shotgun, SAW, and Railgun
Armor Abilities: Active Camouflage
Side: Neutral; formerly Control/Space Pirates
Info: In his first appearance, Locus discovers Washington's call for help after the Reds and Blues are left stranded in an unknown location, but he doesn't respond. Locus later arrives at the teams' location in "A House Divided", then "Multiplied" and begins spying on them (off-screen). When a feud between the Reds and Blues ends and they attack their "rescue team", he remarks the situation is "unfortunate" before cloaking himself.
Locus's first action is killing the pilot that dropped off Doc, Donut, and Lopez. He then reports in to 'Control', stating that his objective is complete and that he's returning to Crash Site Bravo. Back at the crash site, Locus is once again spying on the Reds and Blues, but soon turns his sights on Felix. When the latter notices him, Locus activates his cloaking. Locus is shown again at the end of Reconciliation, this time entering an unknown military base filled with white-clad soldiers and recruits some for a mission.
After launching a sneak attack on the Blues, which lures out Felix and the Reds, he offers the Reds and Blues to join him, but they reject his offer. He later returns with an army against the Reds, Blues and Felix and personally incapacitates and captures Donut, Wash, Lopez, and Sarge.
In the epilogue, it is revealed that the 'Control' Locus reports back to is actually The Chairman.
Locus reappears in Season 12, and in a sponsor cut audio log, it is revealed that Locus knows Agent Washington's name is David. He also makes comments about Locus is not his real name, something Felix has stated before, and that his real name no longer suits him. The other FAC soldiers view him as something inhuman. Locus appeared at the base Tucker was at and killed Cunningham before disappearing when hearing an explosion. He shows back up de-cloaking in Felix's rifle sights.
Kimball reveals later on to Tucker that Felix and Locus were in fact friends and fought alongside each other, but the war changed them both so much they couldn't face returning to civilian life. Felix teams up with the Chorus rebels and, out of rivalry, Locus joins the Imperials to finally find out which one of them is the better. In episode 9 Locus calls himself a "soldier". Locus is then revealed to be working alongside Felix to keep prolonging the war on Chorus for an organization (Control) that intends to use Chorus for their own purposes

Luithin_ {York}
Full Name: Unknown
Codename: New York
Gender: Male
Armor Color: Tan with white trim
Armor Ability: Healing Unit
Implanted AI: Delta
Signature Weapon(s): M45 Tactical Shotgun
Info: Agent New York, referred to as York, is another member of the AI experimental program. York is an infiltration specialist who seems to have become unemployed since the program closed down. His left eye was severely injured in a grenade explosion during a 3 on 1 brawl against Tex, with Wyoming and Maine. Despite his armor's healing unit, his eye did not heal, nor did it later save his life.
He is found by Tex during Part 3 of the miniseries Out of Mind, trying to break into a store. It is revealed that he still had Delta. Here he accepts Tex's proposal of infiltrating Omega's base. At the end of Out of Mind, he and Tex attempt a raid on Omega's base. The two are caught in a firefight against Wyoming and two of his minions. As the two scramble for cover, York is shot twice in the chest by Wyoming, and Delta reports that the bullets were fatal. The AI stays with York and manages to trick Wyoming with a hologram of Tex. Delta chooses to stay with York until his death, rather than go with Tex, appearing to perish with him as the armor shuts down. The healing unit in his armor would later be retrieved, along with Delta, by Washington.
He appears in the trailer for Season 9, where he removes his helmet, revealing the broken eye, and brown/red hair. This marks him as the third character aside from Vic/Vic Jr, North, South. to have his face fully revealed. In Season 9, the origin of his eye wound is revealed. During the paintball fight with Tex, a live grenade meant for Tex is detonated next to him. He is also shown to have some kind of relationship with Carolina, who inquires about his eye when he returns from the hospital. York is shown to have a sarcastic personality. For example, while attempting to organize his team against Tex in the training mission, he makes several sarcastic remarks when his suggestions are ignored. He is also the first Freelancer to officially receive an AI.
It was revealed that he met Carolina at a club, where she takes his lighter from him. During the raid on the Mother Of Invention where Texas attempted to retrieve the Alpha AI York sided with her, telling Carolina that he was 'doing the right thing', after having been told by his AI Delta of Alpha's torture. When facing Carolina York seemed hesitant to fight her and was quickly defeated by her while battling hand-to-hand in a zero gravity environment. Before leaving Carolina threw her cigarette lighter to York, something which brought York great sadness since he understood that she didn't expect to see him again. Whether this was because Carolina now considered York to be a traitor or because she didn't expect to survive her battle with Texas has been left unclear.

Luithin_ {Texas/Tex}
Full Name: Allison Church
Codename: Texas, Beta
Gender: Female
Armor Color: Black
Armor Ability: Active Camouflage, Strength Boost, and Voice Modifier
AI Fragment: Failure
Implanted AI: Omega (removed)
Signature Weapon(s): M7 SMG, BR55 Battle Rifle, M6C Magnum, Spike Grenade
Info: Tex was the last to appear, not debuting until Episode 10. Though she is associated with the Blue Team, she is not an official member, but rather a mercenary "paid" to help them. Her back story with Project Freelancer and previous affiliation with fellow Blue Team member Church are key elements in the plot. Her first name is Allison, but her nickname is Tex, based on her codename from Project Freelancer. With her Special Operations training, she is the most lethal member of the Blood Gulch cast, and especially so while she is still implanted with the Omega AI. Despite her skill, she is shown to be comparatively lacking in endurance and durability as seen in Chapter 19 of Revelation in which her combat ability diminished significantly after taking a bullet, whereas The Meta and Washington were both shown to hold up despite similar, if not worse, injuries. Tex escapes in a ship at the end of Blood Gulch Chronicles, with Andy, Sheila, Gamma, and Omega. This ship crashes in Reconstruction and The Meta steals her as well as Gamma and Omega. Tex is later deleted in the EMP blast set by Washington.
