The Angel Gundam was a newly designed Mobile Suit, that was developed by the Earth Federation in Side 7, that was specially designed for Power, Attack Speed, and Agility. The Mobile Suit was designed and thought of by Mushu Kayoshi, on April 4th, UC.120. It was meant to enter the Zeon Civil War, but the War ended in UC.123, just before the Council of Side 7 gave the project the Green light and construction of the Angel Gundam started.
The Gundam was piloted by the Feminine Angel Daughter of Tanaka Marsha, Sukia Marsha, who after her father's death at the end of the Zeon Civil War, had managed to receive her NewType Ability due to her hatred of War.
Despite being made and designed by Man, the Angel Gundam went down in History as the first ever Mobile suit specifically designed for Females, as most other Gundams that were piloted by Females were often made and constructed for man.
