Nebula started as a comic book character but became one of my favorites thanks to the Marvel movies.

Nebula was created by Roger Stern and John Buscema who first appeared in The Avengers #257 (July 1985).

She also appeared in several animated series.Nebula had her cinematic debut in Guardians of the Galaxy (2014), portrayed by Karen Gillan.  Nebula was also in Guardians of the Galaxy Vol. 2 (2017), Avengers: Infinity War (2018), and Avengers: Endgame (2019).
