This is a list of fictional characters from the Japanese science fiction anime television series After War Gundam X.

Protagonists Freeden pilots and crew

The main character of the series, and a 15-year-old hot-headed boy who is skilled at Mobile Suit operation and espionage. He is initially hired to rescue Tiffa Adill from the Vulture ship Freeden, but upon realizing his employer only wanted to exploit her for her Newtype abilities, he later becomes part of the Freedens crew. Though he is not a Newtype, Jamil notes that he has a natural instinct for piloting, as he is able to quickly adapt to new equipment or situations even under pressure. For much of the series, he nurses a fairly obvious crush on Tiffa but does not act, fearing that the Tiffa would be unnerved by his advances since she was denied most of her childhood. His love for her is what drives him to pilot the GX-9900 Gundam X, the GX-9900-DV Gundam X Divider, and later the GX-9901-DX Gundam Double X. At the end of the series, he and Tiffa go off together when the crew of the Freeden disband, wanting to forge their own future. The GX-9900 Gundam X is a limited-production general-purpose mobile suit fielded at the end of the 7th Space War. Its most powerful armament is the Satellite Cannon, a microwave beam launcher capable of destroying a space colony in a single shot. In the present day, the Satellite Cannon is only usable if there is direct line of sight to the moon, as the moon facility is the only remaining functional transmitter. After Garrod's Gundam X is critically damaged in battle, it is modified into the GX-9900-DV Gundam X Divider, which removes the damaged-beyond-repair Satellite Cannon in favor of a thruster pack and the Divider, equipment that combines a shield, thrusters, and a multi-barrel beam weapon called the Harmonica. The Gundam X Divider ultimately better suits Garrod's piloting style, being more well-rounded and practical than the original configuration. The GX-9901-DX Gundam Double X is a one-of-a-kind unit built by the New United Nations Earth using data from the Gundam X that Jamil Neate piloted during the war. Its most notable feature is the Twin Satellite Cannon system, which is more powerful and more efficient than the original Gundam X's cannon, capable of firing multiple volleys before needing to recharge. The Twin Satellite Cannon retains the need to have direct line of sight with the moon in order to fire.

A mysterious Newtype girl who demonstrates clairvoyance. She is "rescued" by Garrod from the Freeden, but later joins the crew together with Garrod. She is quiet and shy because of what she has seen, and is a frequent target for kidnapping due to her abilities. Thanks to Garrod and the Freeden crew, she begins to open up, and eventually falls in love with Garrod. Although she has paranormal abilities, she does not consider herself a Newtype. As part of the Freeden crew, she uses her abilities to search for other Newtypes, communicating her visions with charcoal sketches. In Gundam X, she and Garrod have two character songs each.

The 30-year-old captain of the Freeden, a Vulture ship. He was once a Newtype pilot of the old United Nations Earth who piloted a Gundam X in the 7th Space War and fired the shot that changed history. The trauma of this event caused him to lose his Newtype abilities and develop a "cockpit phobia" that prevents him from piloting mobile suits. In the present day, he searches the Earth for Newtypes to rescue and protect, wanting to prevent them from being exploited like the Newtypes of his time. Late in the series, he overcomes his cockpit phobia and begins piloting the GX-9900-DV Gundam X Divider after Garrod obtains the Gundam Double X. He holds lingering feelings for fellow Newtype Lucille Lilliant. After the Freeden crew disbands, Jamil partners with Sala Tyrrell and works as a liaison between the Earth governments and the space colonies.

Freedens physician, well versed in numerous disciplines from psychology to 20th-century European poetry. His other interests are equally varied, and include coffee and billiards, with him frequently sneaking into the Freedens lounge for practice. After the crew parts ways, he continues to practice medicine in field hospitals, mediating between soldiers from different sides.

The 18-year-old pilot of the GT-9600 Gundam Leopard and its upgraded form GT-9600-D Gundam Leopard Destroy. Originally, he was only hired to do one job for the Freeden, but he later takes a more permanent position as one of her defenders. Seemingly a shameless skirt chaser at first glance, Roybea cares deeply for every woman he has ever fallen for and is always sensitive to a woman's feelings. Humorously, Roybea also displays the ability to accurately gauge a woman's clothing sizes with just a glance. He won his Gundam in a bet with a woman he considered his true love. Roybea nurses a crush on Sala for most of the series, but she rejects him before the final encounter because of her feelings for Jamil. Six months after the Freeden crew returns from space, he and Ennil El are implied to become a couple and are last seen moving to Witz's hometown. The GT-9600 Gundam Leopard is a heavy ground assault unit. It is armed with numerous weapons, most notably a large rotary cannon mounted on the left arm. When the Freeden travels across the ocean, the Leopard, lacking aerial capability, is modified for underwater combat with a propulsion unit/torpedo launcher mounted on the back. The GT-9600-D Gundam Leopard Destroy replaces the single rotary cannon with two smaller yet more powerful multi-barrel weapons that fit over the hands and adds more weapons such as a shoulder-mounted missile pod.

Freedens 17-year-old bridge operator in charge of communications. In contrast to her crewmate Sala, she is a free-spirited woman who is fashion-conscious and sensitive. She quickly becomes friends with Ennil El at Saint's Island, and although she invites her to join the Freeden, it would take some time for Ennil to join forces. Before the final battle near the lunar base, Witz proposes to her. Six months after the battle, Witz takes her to his hometown, where they become neighbors with Roybea and Ennil.

The Freeden helmsman, who can also be found working in supply procurement, salvaging, guard duty, and trade negotiations. It is said that he is able to pilot even a spacecraft simply by reading the manual.

The Freeden chief mechanic, and a self-styled technical genius at the age of 12. He strives for high quality and professionalism in his work, and will push himself and his subordinates to work beyond exhaustion. He consistently refers to Garrod as "Gundam Boy", initially an insult that turns into a friendly nickname. Despite his professionalism when at work, he is also impulsive with a constant urge to tinker with mobile suits and other machines. His grand ideas, however, lead to powerful upgrades for the Freeden Gundam complement, particularly the Gundam X Divider and Gundam Leopard Destroy. At the series' close, he, along with Shingo, Pala, and his two subordinates Lokoko and Nine open a repair shop and salvage yard called "Freeden III".

The 17-year-old pilot of the GW-9800 Gundam Airmaster and its upgraded form GW-9800-B Gundam Airmaster Burst. Like Roybea, he initially has a one-time contract with the Freeden but eventually joins the crew on a permanent basis. He uses the money gained from his work as a mercenary to support his family, though his mother disapproves of him being a Vulture and mobile suit pilot because his father was killed by a mobile suit. Hotheaded by nature, he holds feelings for Toniya despite their constant bickering and proposes to her before the final battle at the Moon. Six months after the battle, he returns to his hometown with Toniya, now his fiancée, and discovers that Roybea and Ennil will be their neighbors. The GW-9800 Gundam Airmaster is a transformable mobile suit specializing in air combat. It can freely shift modes between mobile suit and aircraft configurations and is armed with twin beam rifles. The upgraded GW-9800-B Gundam Airmaster Burst is more maneuverable thanks to added thrusters and adds a few beam cannons in fighter mode, but otherwise retains the same weapons.

Freedens 19-year-old bridge operator in charge of the sensors and hangar, and second-in-command to Jamil. She has a straightforward, by-the-book attitude that projects a rather stern image, particularly involving Tiffa, as Jamil often focuses on her due to her Newtype abilities. She does, however, grow to become fond of Tiffa when she sees her abilities help protect the Freeden from danger. She confesses her feelings to Jamil before the final encounter with D.O.M.E. and is last seen as his partner during peace negotiations between the Earth Sphere government and the space colonies.

Recurring characters New United Nations Earth

The elder of the twin Frost brothers, working for the New United Nations Earth as a spy. He pilots the NRX-0013 Gundam Virsago and its upgraded form NRX-0013-CB Gundam Virsago Chest Break. He has been under the care of the UNE Newtype Laboratory from his youth, and while he trained with recognized Newtypes, his telepathic ability was not compatible with the Flash System, only being able to telepathically communicate with his brother Olba, and so the lab designated him as "Category F" along with his brother. As a result, he made it his personal mission to eliminate any Newtype candidate that the UNE government ordered him to find out of revenge against the people who would not recognize his power. His thirst for revenge eventually turns into a desire to plunge the world into another destructive war, wanting to rebuild it with him and his brother as its rulers. Cold and ruthless, he is also deeply committed to his cause, and will stop at nothing for its success. He and his brother seemingly perish in their final confrontation with Garrod, but are seen briefly at the end with Shagia in a wheelchair. The NRX-0013 Gundam Virsago is a unique mobile suit featuring extendable arms and a sonic cannon mounted in the abdomen. The NRX-0013-CB Gundam Virsago Chest Break upgrade is tuned for use and space and features a more powerful sonic cannon as well as the ability to combine with the NRX-0015-HC Gundam Ashtaron Hermit Crab and form the Satellite Launcher weapon. The Satellite Launcher is equal in power to the Gundam Double X's Twin Satellite Cannon. He appears as the pilot of the Gundam Virsago in arcade game Mobile Suit Gundam: Gundam vs. Gundam.

The younger of the twin Frost brothers, also working for the New United Nations Earth. He pilots the NRX-0015 Gundam Ashtaron and its upgraded form NRX-0015-HC Gundam Ashtaron Hermit Crab. Although he tries to assume the same attitude as his brother, he is notably more bloodthirsty and aggressive due to feeling a sense of superiority towards others. He is utterly devoted to his brother Shagia, and will usually obey his orders even if his emotions get the better of him. Like his brother, he was considered a "Category F" Newtype because of his incompatibility with the Flash System, his sole Newtype ability being to telepathically communicate with his brother regardless of the distance between them. He and Shagia apparently die after their duel with Garrod, but it is later shown that they survived, with Shagia in a wheelchair and Olba standing next to him. The NRX-0015 Gundam Ashtaron is capable of changing between mobile suit and mobile armor modes, with its main armament being a pair of giant claws mounted on the back assembly. The upgraded NRX-0015-HC Gundam Ashtaron Hermit Crab is tuned for space combat and is able to combine with the NRX-0013-CB Gundam Virsago Chest Break to form the Satellite Launcher weapon.
