Question: are the guardians of the galaxy in endgame?
Answer: "Avengers: Endgame" concludes many characters' stories, but leaves others dangling, notably "Guardians of the Galaxy's" Gamora. Thanos killed Gamora (played by Zoe Saldana) in last year's "Avengers: Infinity War" in order to retrieve the Soul Stone, but she comes back in "Endgame" — or at least, a version of her does.
