Gundam Seed: Cagalli Yula
Cagalli Yula Athha is a fictional character from the Cosmic Era timeline of the Gundam anime metaseries.
Cagalli Yula Athha is the adopted daughter of Uzumi Nara Athha, Representative and “Lion” of the Orb Union, and has the title of princess. She is also Kira Yamato’s twin sister, although neither is aware of this until late in the Bloody Valentine War. In Gundam SEED Destiny, she takes over her late father’s position and becomes the Head Representative of ORB.
While Kira is a Coordinator (a person who is genetically-altered), Cagalli is a Natural. In the Cosmic Era time line, she seems to be the only Natural who can go into SEED Mode.
