!!Seabook Arno
!!!Voice Actors: Creator/KoujiTsujitani (Japanese), [[Creator/SteveStaley Steve Cannon]] (English)

The film's protagonist, Seabook Arno is the son of mobile suit and weapons designers Leslie and Monica Arno. Unaware of the full extent of his parents' work, Seabook ends up FallingIntoTheCockpit of their SuperPrototype, the Gundam F91 when the Crossbone Vanguard launches an attack on his home colony.
* AcePilot: Reaches this status by his second battle.
* BattleCouple: With Cecily at the end.
* TheEveryman: In a sharp contrast to previous protagonists, and his own parents, Seabook doesn't really have any distinguishing characteristics prior to his fateful run in with the titular mobile suit.
* FallingIntoTheCockpit: Downplayed. Seabook discovers the F91 by accident, but volunteers to fly it, since his mother was the one who designed it in the first place.
* LightningBruiser: The F91, as is typical for the protagonist mobile suits. It's faster, harder hitting, and better armoured than anything the Federation or Cosmo Babylonia has at their disposal.
* NiceGuy: Seabook is a fairly pleasant, average kid prior to the events of the film.
* OfficialCouple: With Cecily, who was his girlfriend before the film began.
* TookALevelInBadass: Takes a massive one over the course of the film going from an average student to a battletested veteran pilot.
* YouGottaHaveBlueHair

!!Cecily Fairchild/Berah Ronah
!!!Voice Actors: Creator/YumiTouma (Japanese), Creator/MichelleRuff (English)

Seabook's girlfriend, Cecily Fairchild is the daughter of Carozzo Ronah and the granddaughter of Metzer Ronah, both of whom want her to act as the figurehead for Cosmo Babylonia's conquest of the Earth Sphere. Kidnapped and forced into the role, Cecily keeps her own council, and eventually turns against them.
* AristocratsAreEvil: The only member of her family to avert this.
* BattleCouple: With Seabook at the end.
* BlueBlood
* EvilRedhead: Ultimately averted.
* ExtremeDoormat: Early on, when she just does whatever Meitzer, her father, or any other authority figure tells her to.
* FauxActionGirl: Is so thoroughly clobbered by Carozzo one wonders what she was even doing at the battle.
* GrewASpine: Towards the end of the film she starts to make her own decisions and turns on her father.
* [[spoiler:{{Patricide}}: Helps Seabook kill her father]]

!!Leahlee Edaberry
!!!Voice Actors: Mari Yokoo (Japanese), Jane Alan (English)

A junior Federation Forces officer, who becomes acting captain of the training ship Space Ark once all of the vessel's senior officers leave to fight the Crossbone Vanguard. Her main role in the film is to get the refugees of Frontier I colony to safety before they get embroiled in the war, even if it meant going against the wishes of [[TheNeidermeyer Cosmo Eigesse]].
* {{Expy}}: A junior officer who was [[YouAreInCommandNow the only senior officer]] left in charge of the ship and eventually having to bear the burden to command the ship along with its crews and refugees, which sounds similar to [[Anime/MobileSuitGundam Bright Noah]].
* FieryRedHead: Complete with a hair clip to boot.
* YouAreInCommandNow: With the exception to Cosmo Eigesse, she is commanding the training ship as its previous officers went into fighting against Cosmo Babylonia.

!!Cosmo Eigesse
!!!Voice Actors: Takeshi Watanabe (Japanese), John Smallberries (English)
A former colonel in the Earth Federation Forces, who becomes the leader of the civilian resistance movement after the Crossbone Vanguard attack the Frontier Side. His intention to turn Space Ark into resistance HQ made him an anomisity with the refugees and Leahlee.
* CrouchingMoronHiddenBadass: He may not be a pleasant fellow but he is actually a capable fighter and a tactician. Even managing to down a mobile suit with the resistance cell through fuel barrels and [[SnipingTheCockpit shooting the evacuating pilot with small arms]].
* JerkAss[=/=]JerkWithAHeartOfGold
* LaResistance: Leader of one on Frontier Colony.
* TheNeidermeyer: His wish to draft the refugees and use a training ship as an asset caused frictions with Leahlee and the refugee.

!!Meitzer Ronah
!!!Voice Actors: Teppei Takasugi (Japanese), Simon Isaacson (English)

The leader of the aristocratic Cosmo Babylonia, Meitzer is Cecily's grandfather and Carozzo's father-in-law, and the man who is most to blame for the outbreak of conflict between the EF and the Vanguard. Believing the world is going to run itself into the ground, he aims to save it by imposing his own rule on the Earth Sphere.
* AffablyEvil: Meitzer seems like an okay guy, plans for WorldDomination aside.
* AristocratsAreEvil
* BigBad: He's the one in charge, though Carozzo takes up all the screen time.
* EvilOldFolks: Sixty-nine at the time of the film.
* {{Expy}}: As the elderly, villainous patriarch of a large aristocratic family who leaves all the fighting to his descendents it's not hard to see him as an expy of [[Anime/MobileSuitGundam Degwin Zabi]].
** In fact, Simon Issacson later on voices Degwin in the English dub of the 0079 movies.
* NonActionBigBad: Meitzer isn't really up to much fighting, leaving that to the likes of Carozzo, Dorel, and Zabine Chereaux.
* ThePatriarch: Of the Ronah family.
* TakeOverTheWorld: His end game.
* WellIntentionedExtremist: Claims to be trying to save humanity from itself.

!!Carozzo "Iron Mask" Ronah
!!!Voice Actors: Masaki Maeda (Japanese), Tom Wyner (English)

The son-in-law of Meitzer Ronah, Carozzo is the field leader of the Crossbone Vanguard, and a massively augmented Cyber-Newtype as well. Incapable of removing his mask, Carozzo is able to directly interface with machinery at the cost of his interpersonal skills and his basic humanity, with his wife, daughter, and father-in-law all distrusting and fearing him. He pilots the ''Rafflesia'' mobile armour.
* ArchnemesisDad: To his daughter, Cecily, whom he eventually tries to kill.
* AxeCrazy
* BatmanCanBreatheInSpace: Suffers no ill effects when he emerges from the ''Rafflesia'' into hard vacuum. It could be that his mask contains an air supply, or that his Cyber-Newtype modifications included some sort of alternative form of respiration, but since neither is specified, this trope is still very much in effect.
* BeamSpam: With the heavily armed ''Rafflesia''.
* CharClone: He's more like Darth Vader in looks, but he still plays the role of the Char character in the film, with his personal connection to a cast member, CoolMask, and red mobile armour.
* CombatTentacles: His personal mobile armour, the ''Rafflesia'', features these.
* CoolHelmet[=/=]CoolMask: An elaborate steel mask that completely conceals his head.
* CyberneticsEatYourSoul: Whatever human qualities Carozzo once had, he's lost them since becoming a Cyber-Newtype.
* {{Cyborg}}
* DarthVaderClone: He not only has the look but hits many other aspects of the character, right down to Cecily accusing him of being nothing more than a machine.
* DragonInChief: Meitzer is the actual BigBad of the film, but Iron Mask is the true threat to the main cast, and the movie ends with his defeat.
* TheDreaded: Within the Crossbone Vanguard.
* EvilLaugh: He gives off a few during his battle with Seabook and Cecily.
* TheHeavy: He's the one who drives the plot of the film.
* ImmuneToBullets: Cecily's bullets bounce right off of him.
* KnightTemplar: A particularly brutal one, who intends to reduce the population of Earth and the colonies by ninety percent so that the human race as a whole can survive on dwindling resources.
* LackOfEmpathy: Deliberately abandoned his empathy so that he could do what he thinks he has to do to bring about Meitzer's goals.
* MightyGlacier: The ''Rafflesia'' when compared to mobile suits like the F91.
* SuperStrength: Able to tear open the cockpit of Cecily's mobile suit using only his hands.
* {{Technopath}}: Can directly connect to and control his personal mobile armour.

!!Dorel Ronah
!!!Voice Actors: Creator/TakeshiKusao (Japanese), [[Creator/DaveWittenberg David Lelyveld]] (English)

Carozzo's son and Cecily's half-brother, Dorel Ronah was adopted into the larger family by Meitzer when Carozzo married Cecily's mother. Arrogant and determined to prove himself, Dorel acts as one of Meitzer and Carozzo's mobile suit pilots, spearheading the initial attack on the colonies. He has a rivalry with Zabine Chereaux.
* AcePilot
* AristocratsAreEvil: Though significantly less so than his father and adoptive grandfather.
* BladeOnAStick: Seems to favour the lance as a weapon.
* TheRival: Sees Zabine Chereaux as his.
* YouGottaHaveBlueHair: Purple, actually.
