What is your favorite plot twist in an anime series?

Just rewatched "Code Geass" and the mind-blowing plot twist when Lelouch turns out to be Zero still gets me every time. The way the show plays with your expectations and flips them on its head is just so innovative. What is your favorite plot twist in an anime series? Mine would definitely have to be this!

Ah, "Code Geass"! That was a solid twist, no arguments there. But if we're talking about mind-bending turns, I'd go for "Attack on Titan" when we learn who the Colossal and Armored Titans really are. That revelation was like a punch in the stomach!
