List of Mobile Suit Gundam 00 Characters - Antagonists - First Season - Union

The World Economic Union (世界経済連合, Sekai Keizai Rengō?, abbrev. Union (ユニオン, Yunion?)), also referred to as the Union of Solar Energy and Free Nations (太陽エネルギーと自由国家連合軍, Taiyō Enerugī to Jiyū Kokka Rengōgun?), is a supranational politico-economic community consisting of the Organization of American States, Australasia, and Japan. It controls the first-completed of the three orbital elevators, located in South America.

Graham Aker (グラハム・エーカー, Gurahamu Ēkā?)

Graham Aker is an antagonist of the series and is often considered the archrival of Setsuna F Seiei. Prior to the series, he joined the military to live his dream of flying and became an ace pilot. However, a freak accident resulting in the death of a superior officer and his sudden promotion made Graham a victim of rumors. When Celestial Being makes its appearance in the world, Graham is promoted to Captain of the Over Flags. Though he originally had a love for the Gundams, the actions of Team Trinity causes Graham's feelings to exceed into utter hatred. In the final moments of Operation Fallen Angels, Graham uses the GN Flag to attack Setsuna, exchanging blows and clashing ideals with him before the battle ends with Graham receiving scars on the right side of his face. Four years later, Graham dons a mask to cover the scars and becomes a member of the newly formed A-Laws under the alias of Mr. Bushido (ミスター・ブシドー, Misutā Bushidō?). Possessing a one-man army pass, Graham was given special permission to do as he wishes during battles, preferring to battle Setsuna. Graham is the Union's ace pilot and follows a strict code of honor. With a skill unmatched by any Flag pilot, Graham is eager to find an opponent worthy to fight. When Gundam Exia first appeared in the AEU exhibition and destroyed their new unit, the Enact, he grew completely interested in the Gundam's capabilities, as Billy Katagiri notes, he's "quite infatuated" with the Gundams. After losing to Setsuna, who spared him, Graham takes Setsuna's words to live to heart while he is contemplating seppuku. In the end of series, he is standing back of door watching Billy work. In the Gundam 00 Movie, he sacrificed himself to help Setsuna to get in to the ELS core.Graham Aker is voiced by Yuichi Nakamura in Japanese and Paul Dobson in English.

Billy Katagiri (ビリー・カタギリ, Birī Katagiri?)

Billy Katagiri is a mobile suit developer and friend of Union ace Graham Aker. After the appearance of Celestial Being, Billy, Graham, and Professor Ralph Eifman, who had taught Billy in college, are transferred to the Anti-Gundam Investigative Task Force, later named "Overflags". Billy is a former classmate of Leesa Kujo (aka Sumeragi Lee Noriega) and inadvertently leaks information about "Project G" to her and Celestial Being. After the death of Professor Eifman and Howard Mason during an attack by Team Trinity, Billy uses one of the recently acquired GN Drives to upgrade Graham's Flag unit to the GN-Flag in order to fight the Gundams.

By the second season, Billy is taking care of a despondent Kujo, still unaware that she was a member of Celestial Being until Setsuna F Seiei appears to retrieve her. Shocked by this revelation and feeling betrayed, Billy joins the A-Laws and becomes the head of mobile suit development. Once again teaming up with Graham Aker, now using the alias Mr. Bushido, Billy develops the Masurao and the upgraded Susanoo. Billy disappears after the collapse of the African orbital elevator, but reappears four months later to provide his Trans-Am findings to the Innovators as he personally confronts Kujo while claiming to embraced the Innovators' ideals of world peace. However when exposed to the 00 Raiser's Trans-Am, Billy is forced to expressed his feeling to Kujo as she apologized for hurting him. In the ending of series, a picture of him and Kujo shown in front of desk when Billy himself smile looking his picture doing his work while Graham standing on back watching him Billy Katagiri is voiced by Yūji Ueda in Japanese and Kirby Morrow in English.

Howard Mason (ハワード・メイスン, Howādo Meisun?)

A Union NCO with the rank of Warrant Officer. One of the first Flag Fighters assigned to the Anti-Gundam Investigative Task Force "Overflags" under Graham Aker. He seemed to have a friendship with Graham due to their belief in the qualities of the Flag. He has brown hair and glasses. He was killed in action by Michael Trinity. After his death, Graham and Daryl vowed to avenge his death. Howard Mason is voiced by Kenji Takahashi in Japanese and Trevor Devall in English.

Daryl Dodge (ダリル・ダッジ, Dariru Dajji?)

A Union soldier with the rank of Master Sergeant. Another of the first Flag Fighters assigned to the Anti-Gundam Investigative Task Force "Overflags" under Graham Aker. Unlike Graham and Howard, he doesn't share their faith that a Flag can beat the Gundams. He is transferred to the Union's GN-X squad where he meets Patrick Colasour and tells him not to badmouth Graham. He is killed after performing a head-on suicide attack on Gundam Dynames in order to avenge Howard Mason's death. Daryl Dodge is voiced by Rintarou Nishi in Japanese and Scott McNeil in English.

Ralph Eifman (レイフ・エイフマン, Reifu Eifuman?)

A world famous Union professor who is invited to join the Overflags as their technical chief. He taught both Sumeragi Lee Noriega and Billy Katagiri in college and knows them both well. When Graham asks him whether the Gundams' action may bring the world to an end, Eifman does not deny the fact. Professor Eifman joined the Union's Anti-Gundam Investigative Squad as their technical chief and adviser to aid in capturing the Gundams. Having Billy at his side, they custom modified Graham Aker's Flag and renamed it as "Over Flag." Eventually these modifications were expanded to an entire squadron of Over Flags to stand against the Gundams. While doing his investigation regarding Celestial Being, Eifman was on the verge of a major revelation about their ultimate intention but was killed by Team Trinity. Ralph Eifman is voiced by Takaya Hashi in Japanese and Ron Halder in English.
