Hikari Yamato (Newtype Series)

"Hikari is innocent and hates war, but even she has been bloodied by her actions and they never return to a permanent peace, which is why we must fight her even if it means killing her. I don't know about you, Shinn, but the Newtype Goal is more important than her pathetic life...Newtype or not!"

- Kira Li Creuset when talking about his Sister to Shinn Asuka.

Theoretically she is the Antagonist of the Series or Main Protagonist if you think from Gundam Seed's perspective, Hikari replaces Kira Yamato as pilot of the Strike, Freedom and Strike Freedom.
