Geass
Kujapat's Geass is the ability to reverse a person's perception of who their foes and allies are. This causes a person to see their allies as their enemies, such as causing Kallen to see her friends as multiple Kujapat, and vice versa. While the effect can be problematic, if the target has prior knowledge of the effect then they can act accordingly, such as with Sayoko The effect appears to require constant contentration of the Geass user, though, as it wore off when he was knocked unconscious.
