Mobile Suit Gundam 00/Characters/Union and Free Nations

Everything About Fiction You Never Wanted to Know.



Graham Aker

Ace Pilot of the Union, and something of a Fan Boy when it comes to Japanese things. Graham tends to relate things with Japanese, following some sort of Bushido code, yelling about surpassing Ashura in battle, etc. Despite that, he is not a Japanophile, but one of the best pilots in the world, being the first to deal any substantial damage to a Gundam without a scratch. He also has a bizarre attraction to the Gundams (or more specifically, Exia), often talking about them in romantic terms even as he fights them. In response of the death of his comrade Howard Mason at the hands of Gundam, Graham made a vow to defeat the Gundam with just using Flags. He fought Setsuna after the latter defeats Alejandro Corner, and fought to a stalemate.

In the second season, he returns wearing a mask, now calling himself Mr. Bushido. He finally got his personal unit called "Masurao", a customized Flag using dual katana, which was built by his friend Billy Katagiri. It later got upgraded into "Susanowo" and he finally reveals his identity to Setsuna for the first time.

Mr. Bushido: Hajime Mashita Gundam Musou![1]

Mr. Bushido: All right! My first time as a Dynasty Warrior Gundam!


Billy Katagiri

A mobile suit developer and friend of Union Ace Pilot 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 Sumeragi Li Noriega (aka Leesa Kujo) 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 appears to retrieve her. Shocked by this revelation, 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 later the upgraded Susanowo.

Graham's Wingmen

Howard Mason is 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 was killed in action by Michael Trinity. After his death, Graham and Daryl vowed to avenge his death.

Daryl Dodge is a Union soldier with the rank of Master Sergeant. Another 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 killed after performing a head-on suicide attack on Gundam Dynames in order to avenge Howard Mason's death.

In season 2, Graham named his Masurao's two swords "Howard" and "Daryl" in their loving memory.
