Avengers: Endgame - Every Major Character's Best Moment

11. Nebula "Kills Herself"

Endgame's timey-wimey shenanigans ultimately result in Nebula coming face-to-face with her malevolent past self, who takes her place among the Avengers and ultimately allows Thanos' army to travel from 2014 to 2023.

But in an amusing confrontation, present Nebula tries to convince past Nebula of her better nature, yet it's ultimately to no avail, and she's forced to shoot her past self dead.

In addition to fully crystallising the movie's time travel logic - where affecting the past doesn't affect the present - having Nebula literally kill her past is a handy visual metaphor for her more heroic demeanour these days.
