A mobile suit pilot, black market weapons dealer, and thief for hire, Garrod is initially contracted to kidnap Tiffa from Vultures led by Jamil Neate. After realising that he has been working for the wrong side, Garrod makes a run for it with Tiffa in tow, stumbling onto a GX-9900 Gundam X from the previous war in the process. Forced to pilot the machine in order to save their lives, Garrod joins up with Jamil's Vultures in order to continue protecting Tiffa. Enthusiastic, confident, and with some hideously awful trust issues just below the surface, Garrod matures into an excellent pilot even as he learns that sometimes, it's okay to rely on other people.
BFG: The shoulder-mounted Wave Motion Gun on the X is the length of the Gundam itself and can wipe out entire battalions. Following the loss of its sattelite uplink and the upgrade to the X-Divider, this is replaced with a battleship grade beam cannon, wielded like the beam rifle on any other Gundam. The Double X restores the original Wave Motion Gun and adds a twin on the opposite shoulder.
BFS: The X's beam sabre is roughly the length of the robot itself during its first use. Later apperances tone it down.
Character Development: He has to learn to be less reckless and interact better with others as time passes.
Shoulder Cannon: His BFS deploys over one of his shoulders when activated. The Double X adds another BFS, deploying over the opposite shoulder.
Street Urchin: He's hinted to have spent some time as one after he lost his father and only relative at an early age.
Super Prototype: The X might be salvaged from the last war, but the Double X is brand new, and one of a kind.
Wave Motion Gun: The X's ace in the hole is a massive microwave cannon mounted over its shoulder. Powered by solar cells on a lunar base, the cannon can wipe out entire mobile suit squads in seconds. The Doulbe X features two of them.
A young girl with strong psychic abilities, Tiffa's future sight makes her a target for the warring factions. Quiet, innocent, and prone to fainting, Tiffa is bombarded by horrible visions of the future, which she often seems determined to make come true. Upon meeting Garrod she realises that she is tied to him for better or for worse, and puts him in the position of having to fly the Gundam X.
All-Loving Hero: Even more then Garrod, Tiffa believes the absolute best in people.
A one-time Federation ace, Jamil Neate is now the shellshocked captain of the Freeden, a landship filled with Vulture junk scavengers. Determined to ensure that no Newtypes ever endure what he went through, Jamil brings Tiffa onboard to protect her from the scientists who wish to exploit her talents. Unfortunately, in doing so, he makes the Freeden a target for every political and corporate faction around...
A Father to His Men: It takes a lot to get him to show it, but Jamil cares deeply for the people under his command.
Ace Pilot: In the backstory. He hasn't actually flown in years.
Badass: Follows in the proud Gundam tradition of captains being every bit as tough as their pilots.
Jamil's second-in-command, Sala has a fairly obvious crush on her boss, which she does her best to keep under wraps. Increasingly aware of just how screwed up Jamil is, Sala tries to lighten his load, though her curiosity about his past, and desire to keep him away from other potential love interests sometimes sabotages her.
Armor-Piercing Slap: Uses it at least once against Garrod, though to be fair she did it when Jamil got severely injured in the course of saving Garrod.
A freelance mobile suit pilot in the employ of Jamil Neate, Roybea is a consumate ladies' man with a healthy respect for his own skin, and a history of friendship with Witz Sou. Piloting the Leopard Gundam, Roybea acts as fire support for Garrod, Witz, and the rest of the team, using its substantial arsenal to lay down suppressive fire.
Ace Pilot: Already a feared mercenary when the show starts, Roybea's an ace many times over.
Gatling Good: The Leopard Gundam comes equipped with two of these—one on the wrist and the other carried as a weapon. It also has a Vulcan cannon in the chest to complete its complement of multibarreled weapons.
Hired Guns: Roybea's a mercenary and a good one at that.
Lady Killer In Love: He eventually gets hit with this when he falls for Sala and even more so, for Ennil.
The Lancer: To Garrod, in battle, acting as second command and fire support.
Lightning Bruiser: The Leopard is very fast, and very heavily armed/armoured. What stops it from reaching Game Breaker status is that it cannot fly.
More Dakka: With built in gatling guns, grenade launchers and missiles, Roy's Leopard is set to do some damage.
Macross Missile Massacre: Why settle for bullets, when you can also unload every conceivable missile type on the planet?
Only in It for the Money: Roybea is a mercenary, which means he has to live to spend the money he makes. Therefore, other considerations tend to come second, at least early on in the show.
Red Oni, Blue Oni: The Blue to Witz's Red, which somewhat translates into the color of their mobile suits (in Japanese, the characters for blue and green [ao] are curiously interchangeable). When he learns to be more headstrong and committed in battle, the Leopard Destroy similarly upgrades to a red paintjob.
Second Love: With/to Ennil after they both lose out on their first choices.
Another mercenary, Witz is good friends with Roybea, whom he tends to partner with on contracts. Piloting the Airmaster Gundam, Witz acts as the team's air support, hitting opponents from above. Always the first into a fight, Witz hates to run away. He has a complicated relationship with his mother, and siblings, and frequently pretends to be a far bigger jerk then he really is.
Ace Pilot: Holds this status long before the show starts, and earns it over and over again throughout it.
Badass: He and Roybea take out an entire Vulture mobile suit force in episode 3, by themselves, firmly establishing their badass credentials in the process.
Berserk Button: Don't touch Witz's money. The three guys who do discover that he's not joking when he says he'll "follow you into the depths of Hell!"
The Big Guy: In battle. Witz doesn't think. He just charges right in, relying on Jamil, Garrod, Roybea, etc, to worry about the tactical details.
Boisterous Bruiser: He has some elements of this, ordering Roybea to stay back at one point so that he can have some fun.
The Dutiful Son: Has problems with his mother because he refuses to be one.
Guns Akimbo: The Airmaster wields one laser pistol in each hand when in robot mode.
Hired Guns: He and Roybea are both on contract with Jamil to act as guards.
Hot-Blooded: Witz charges into fights with even more abandon then Garrod.
Jerk with a Heart of Gold: He does care for his friends and family, despite how rough around the edges he is. He drops off a mobile-suit sized stash of gold to his family so they can have a good life until he comes back home
Red Oni, Blue Oni: The Red to Roybea's Blue, which somewhat translates into the color of their mobile suits. When he begins to learn how to become a bit more focused and tactical in battle, the Airmaster Burst similarly upgrades to a blue paintjob.
Spiky Hair: You start to wonder if it's jelled after a while.
The Medic: The only member of the Freeden's medical team that we actually meet.
Shown Their Work: A large number of Texans are of German descent, which is something not many people outside of Texas, let along the US are aware of (unless maybe they watch a lot of King of the Hill, since this fact comes up in a few episodes).
A confident young man with a flair for tactics, a talent for piloting, and his own fair share of secrets, Shagia Frost and his brother, Olba, operate as freelance mercenaries, taking work for whoever will pay them. Initially contracted to recapture Tiffa from Vulture, Shagia is slowly revealed to have his own agenda where Newtypes and the oncoming war are concerned. He pilots the Visago Gundam.
Freudian Excuse The reason why he and Olba wanted to start a war that would kill everybody? They're mad at the world for being considered worthless failures, as they were born as Category Fs and not "proper" Newtypes. This leads them to despise the very concept of Newtypes as inherently superior humans. Ironically, he and his brother are the only major characters not present when D.O.M.E., the "original Newtype", reveals that the idea of Newtypes as the next step in human evolution is complete bunk.
This is actually why the Frost Brothers are more popular among western Gundam fans than in Japan. Japan found them to be disappointing because they were expecting some big dramatic master plan by them, or something showing them to be characters along the lines of Scirocco. When it was revealed that they were simply two brothers who were angry at the world because of their own insecurities and out of sheer pettiness, that fell through. However, Western fans found it made them feel more human and believable as antagonists, and was refreshing compared to the constant "master plan" villains.
Hand Blast: The Visago mounts a laser in between the claws on its hands.
Hired Guns: Presents himself as a mercenary in order to switch sides as often as necessary.
The younger twin brother of Shagia Frost, Olba is his brother's confidant, right-hand, and coconspirator. Totally devoted to Shagia, Olba suppresses his own personality and hopes in order to make his big brother's dreams a reality, leaving himself rather unstable beneath the surface. He, like Shagia, is a talented mobile suit pilot, and operates the Astaroth, a transformable Gundam with a mobile armour alt-mode.
Ace Pilot: A top-notch pilot, with plenty of kills under his belt before the series even begins, Olba cements his status by taking on the Leopard, Airmaster, and X-Divider in a three-on-one match after Shagia is hurt, and not only performing well, but emerging all but unscathed.
Ax-Crazy: Both brothers are dangerous, but Olba is the one who tends to go berserk.
Psycho Supporter: Of his brother. In addition to being an Axe CrazyStraw Nihilist, Olba's brother complex is so strong that he more or less subordinates his entire identity towards making his brother's dreams become a reality.
The Resenter: Of Newtypes, their fans, and the rest of the world.
A strange New Earth Federation pilot and candidate Newtype, Griffe is the first of the officers under Shagia and Olba Frost's command to be sent out against the Frieden and its crew. He favours lightweight suits, specifically his NRX-007 Correl, and the colour white.
Ace Pilot: Had this status before getting sent out to face Garrod.
Badass: Nearly takes out the Double X using only a lightweight mech and a knife.
A New Earth Federation mobile suit pilot, Draid is one of several candidate Newtypes placed under Shagia and Olba Frost's command. The pilot of the gigantic NRX-010 Gable, Draid is an adrenaline junkie who admits that he is looking to die.
Mighty Glacier: The Gable is huge and slow, but virtually indestructible.
Nigh-Invulnerability: The Gable's shielding renders it immune to almost all ranged weapons, and most close up ones. It takes close range fire from heavy projectile weaponry to even come close to damaging it.
The new leader of the SRA, Rasso has transformed the colony of Cloud 9 into a Police State. Claiming that Newtypes can only emerge in space, Rasso preaches that the colonies have an inherent right to conquer and rule the world.
Bad Boss: Has Nichola executed for suggesting peace negotiations.
A one-time enemy of Jamil Neate's, Lancerow lost his Newtype powers during the waning days of the war. Currently an instructor and captain in the new SRA, Lancerow has some serious doubts about Siedel Rasso's goals.
Ace Pilot: One of the best pilots of the previous war.
Antivillain: Which is why he ultimately switches sides.
Bishōnen: A less extreme case than many on the show.
Expy: An interesting variant. His personality is modelled not on Char (who was essentially a complete jackass), but on the Draco in Leather Pants version of Char that exists in the fandom. He's not so much as expy of Char as he is the realisation of who the fandom wanted Char to be.
Expy: Blue machine? Bonds with a protagonist over drinks? Connections to the Space Colonies due to her father being a high-ranking war hero? Ennil is either this series's equivalent to Ramba Ral or her Disappeared Dad Nada El was this series's equivalent to Ramba Ral.
I Just Want to Be Normal: Toys with this around the middle of the series, working in a bar and having a tentative romance with a civilian while being tempted with a new mobile suit. She chooses piloting and later learns that her would-be fiance died in an attack.
Pet the Dog: She strikes up a genuine friendship with Toniya (not knowing she's from the Frieden), showing that she's more than an immoral enemy pilot and that she's not entirely happy with what her life is. She also tries to get Toniya protected after tipping off the Feds to the crew's escape attempt when captured.
Revenge Before Reason: She teams up with Nomoa Long and other unsavory types in her attempts to get back at Garrod.
Stalker with a Crush: Sneaks into Garrod's room to try and convince him to sleep with her, and when he shoots her down, takes the rejection very badly, following him everywhere and plotting to kill him.
Stripperiffic: Her costume has very little actual material in it.
Yandere: Briefly acts as one towards Garrod, stalking him everywhere he goes, and plotting to murder him. She gives it up after befriending Toniya.
An Artifical Newtype created by Nomoa Long, Carris initially acts as a villain, seeking to unite the world and clashing with Garrod because of it. After his defeat, he realises how wrong he was, and pulls a Heel-Face Turn.
Formerly a scientist with the Space Revolutionary Army, Nomoa Long (once Professor Dorat) hides out on Earth under an assumed name. Having become Mayor of Fort Severn, he plots his revenge on the United Nations Earth for defeating the SRA.
Manipulative Bastard: Preys on Carris' hopes of saving the world in order to get him to do what he wants.
Mayor Pain: Nomoa acts as the mayor of Fort Severn, planning to use it as a stepping stone in his plan to reunite the world under Carris Nautilus. A lot of the town's funds get diverted to his private projects, which ultimately destroy much of Fort Severn upon activation.
Fan Disservice: She's seen naked during the whole time she's been locked inside her capsule. While Lucille's extremely beautiful and we don't see stuff usually related to Fan Disservice (fluids, blood, guro, etc.), it's not fanservicy because as mentioned above, she's basically unconscious all the time and the circumstances surrounding her nudity are terrible..
Pala SysA pilot from Satelicon who bails Garrod out during a bad fight with Lancerow Darell, Parla quickly strikes up a friendship with Garrod, and joins up with the Frieden's crew, using her G-Falcon to back up their Gundams.
DOMEThe automatic defense system for the Microwave Generator on the Moon that supplies power to the Satellite Cannon. It was built out of the body of the first Newtype to ever appear, and his mind is still active within the system.
Brain Uploading: Apparently unintentionally. The Old Federation just wanted his Newtype powers for the system, but wound up getting his consciousness as well.
Evolutionary Levels: Thoroughly debunked. DOME is very strongly of the opinion that Newtypes are neither more evolved nor any different from any other human being: they just happen to have special talents. DOME further states that the ideal of a "Newtype" is nothing more than a fiction made up by people desperate for a "savior", and they are not an existence that will solve humanity's problems.
Heroic Neutral: It attacks anyone, be they from the Federation or Space Army, who comes near the lunar facility, because it knows they only want its power for destruction. Given that it has a small army of G-Bits equipped with Satellite Cannons at its disposal, most don't dare attempt an attack. It only allows the Frieden crew (and representatives from the other powers) into the base because it sensed, through Tiffa, their strong desire for peace.
Psychic Powers: DOME's human body has long since been lost, but its Newtype powers are still there. It is by far the most potent Newtype seen in the show.
Transhuman: It doesn't appear to consider itself a human being anymore. Emphasized by its "appearance" as a small ball of blue light, rather than anything resembling the human form.
Walking Spoiler: It is only first mentioned about seven episodes before the end, and almost nothing about it is revealed until the final two episodes. The characters meeting with DOME also triggers the end of the main conflict.
