This is a list of characters that appear in the Japanese anime television series and subsequent spin-offs.

Shuffle Alliance The Shuffle Alliance is a public team that watches humanity from the shadows and intervenes to prevent conflicts from escalating. It consists of five members: Domon Kasshu, Chibodee Crocket, Georges de Sand, Sai Saici, and Argo Gursky, who are the strongest fighters of their generation. Its name is derived from the fact that each member bears the crest of a playing card: King of Hearts, Queen of Spades, Jack of Diamonds, Ace of Clubs, and Black Joker. Their crest appears on their right hand as well as when they perform special attacks or are in an emotional state.

The original Shuffle Alliance consisted of Master Asia, Tris Sergeyrev (Black Joker), Nassius Kircher (Jack of Diamonds), Max Burns (Queen of Spades), and Alan Lee (Ace of Clubs) until Master Asia, who grew disillusioned following his victory in the 12th Gundam Fight, left after bestowing his title to Domon Kasshu. During the 13th Gundam Fight, the remaining members face Master Asia and Domon's friends Chibodee Crocket, Georges de Sand, Sai Saici, and Argo Gursky, who had been infected with the DG Cells, at Shinjuku. After sacrificing themselves to burn away the DG Cells and free them from the Dark Gundam, they bestow them with their crests before dying.

Before the 13th Gundam Fight, he spent ten years training under Master Asia, from whom he inherited the crest of King of Hearts. During the 13th Gundam Fight, he agrees to represent Neo-Japan and competes to find his brother Kyōji, who stole the JDG-009X Devil Gundam and free his father, Dr. , who was placed in cryogenic suspension for his involvement in the creation of the Devil Gundam. Domon is short-tempered and determined, willing to do whatever it takes to complete his mission, and can be uncaring due to his dedication to the mission. He is dependent on Rain Mikamura, his childhood friend and his partner in the Gundam Fight, and the possibility of losing her makes him either snap or feel lost. Though he struggles to accept that Master Asia had allied with the Devil Gundam, he overcomes this and becomes a better fighter with help from his surrogate teacher Schwarz Bruder. Towards the end of the series, he learns the truth about the Devil Gundam incident and why Master Asia allied with the Devil Gundam. At the end of the series, he confesses his love to Rain, who agrees to live on Earth with him, and they later marry.

He becomes Domon's rival after losing to him in a Gundam Fight in New York City and fights him in Tokyo after being possessed by DG Cells, but is stopped by the Shuffle Alliance, who heal him, and becomes the Shuffle Alliance's new Queen of Spades. He had a fear of clowns due to an incident when he was young, which he overcomes after fighting an opponent dressed as a clown. Chibodee initially does not get along well with fellow Gundam Fighter/Shuffle Alliance member, Georges de Sand, who is his opposite in that they grew up in different financial classes and fight for different, pride-based reasons.

Georges considers himself to be a knight and fights for the pride of his nation and its princess, Maria Louise. In the past, he was involved in the Marseilles Tragedy, which occurred when he fought Jean Pierre Mirabeau in a competition to determine Neo-France's representative. After Jean Pierre Mirabeau stood in front of the crowd with his Mirage Gundam to prevent Georges from attacking, the King of Neo-France disqualified him for his dirty tactics and declared Georges the winner by default. Mirabeau attempted to kill the King in revenge; although Georges attempted to stop this, the Mirage Gundam's missiles redirected into the stands, killing thousands of spectators. Georges later becomes the Shuffle Alliance's new Jack of Diamonds and faces Mirabeau again when he escapes from a prison colony with help from the Devil Gundam. When Mirabeau arrives in Guyana, where Georges was training for the finals, he overcomes his fear of the Tragedy and uses his new power as the Jack of Diamonds to heal Mirabeau, who had been infected by the DG Cells. When the King refuses to allow him to fight Domon in the finals, he steals Gundam Rose from its hangar, risking his position as a Gundam Fighter and his family's honor.

His special techniques include Rose Screamers, Rose Bitz, and Rose Hurricane. His name is derived from George Sand.

Pilot of the Dragon Gundam and representative of Neo-China, whose fighting style is shaolinquan; at 16 years old, he is the youngest Gundam Fighter. His support crew consists of the elderly Shaolin monks Zuizen and Keiun. When the colonies were formed, most of the Shaolin followers defected to the Chikurin temple. Because of this, he competes in the 13th Gundam Fight in order to convince the Neo-China government to revive the Shaolin Temple. In the past, his grandfather competed in the 4th Gundam Fight and his father was stricken with a terminal illness. When Domon first meets him, he is accused of attacking Neo-China, but in reality he was separated from the Dragon Gundam and used Domon to help him get it back. He later becomes the Shuffle Alliance's new Ace of Clubs.

Pilot of the Bolt Gundam and representative of Neo-Russia, who uses grappling-style wrestling moves and, unlike many of his fellow Gundam Fighters, initially does not rely on special techniques. His support crew consists of his warden, Nastasha Zabigov, who was assigned to watch him after Neo-Russia was forced to change its tactics. In the past, he was a Space Pirate Captain and, though a criminal, valued life and did not kill. After being caught, he was forced to become Neo-Russia's Gundam Fighter to ensure the safety of his crew and had a bomb attached to his chest to prevent him from going out of line. Neo-Canada's Andrew Graham holds a grudge against him because he blames him for his wife's death, even though it was an accident. When he first meets Domon, he stages an escape to fight him after being disgusted by Neo-Russia's tactics of luring in Gundam Fighters and arresting them so that they do not have to fight. He later becomes the new Black Joker of the Shuffle Alliance and is older than the other new members. At the end of the series, Natasha deactivates his handcuffs and the bomb on his chest so that he can fight without holding back. His special techniques include the Gaia Crusher and Graviton Hammer.

Afterwards, she returns to Neo-Japan, where her former boss, Major Wullube, kidnaps her and puts her in the cockpit of the Devil Gundam. However, she is freed through the combined efforts of Domon, the Shuffle Alliance, Allenby, and other Gundam Fighters, and Domon confessing his love to her allows her to break through her self-imposed emotional barriers and the Devil Gundam's control over her body.

Chibodee Crockett's support crew and cheerleading squad, which consists of , , , and . They were once street gang members who stowed away on a colonist ship and were almost caught until Chibodee saved them from the legal trouble they would have gotten into, with them serving him in order to repay the favor.

They, along with the crews of the Shuffle Alliance's members, support the Alliance from Argo's pirate ship during the final fight against the Devil Gundam.

Shaolin monks and martial artists who serve as Neo-China's support crew and as Sai Saici's surrogate guardians. They are old friends of Sai Saici's late father; before he died, they promised to raise his son to revive the Shaolin Temple, a task that they and Sai Saici take seriously. They come into conflict with Domon when they kidnap Rain in order to get him to defeat an impostor who stole the Dragon Gundam and posed as Sai Saici, and with Sai Saici when they plan to use Argo Gursky to fight Sai Saici, who had refused to train after their first encounter with the Devil Gundam, to get him back into training by fighting a strong opponent.

The tomboyish 14-year-old daughter of Neo-France's current ruler and its princess, who is in love with Georges de Sand. When Georges initially refuses a match with Domon, Maria, with help from Domon, stages her own kidnapping in order to get Georges to consent to a match: Domon for the sake of a fight, and for Maria to feel as though Georges was fighting for her alone. Both get what they wanted, and Georges reveals that he knew it was staged, since Domon would not have been able to write the ransom note in French. Though her father sends her back to the Neo-France colony as punishment for the incident, she later returns during the finals. She eventually matures enough to help the Shuffle Alliance in their quest to destroy the Devil Gundam. When she witnesses the undead Chapman murder a Neo-England official, she and the other members of the Neo-France team are held at gunpoint as Michelo deactivates the part of the barrier that protected them from Chapman during his match against Georges. After Georges protects them while Domon, Rain, and Allenby fix the barrier system and reactivate the barrier, she identifies Wong as the other man involved in the murder by recognizing his ring, but her father tells her to forget the incident because of Wong's position. She later helps in standing up to her father's selfish decision of not having Georges fight against Domon in the finals, aids the support crews in breaking down an energy barrier in order to allow Rain and Schwarz to deliver the truth to Domon during the Battle Royale, and assists the Shuffle Alliance during the final fight against the Devil Gundam by wielding a gun turret.
