Rei Ayanami

Rei Ayanami is a character from Neon Genesis Evangelion and is a major character in The Knights of the Multiverse, introduced in Season 2. Originally the pilot of Evangelion Unit 00, she initially joined with Axis Zeon when they "rescued" her and go on to pilot the Snapping Turtle, the Strike Dog, and later the Rabidly Dog, before joining the Crystal Knights.

Personality
For the most part, Rei is socially withdrawn, seemingly emotionless, and rarely interacts with anyone. She appears emotionless and depressed and will follow orders without question (which can sometimes be viewed as obedient and passive), even if it means risking her life. In battle, she has no self-preservation instinct and will not ignore orders to save herself.
