Ayesha and the Sovereign are secondary villains to Ego the Living Planet in Guardians of the Galaxy Vol. 2, but they all make quite the impact in the sequel and it's clear that will be the case for Vol. 3 as well. That's because one of the after-credits scenes sees Ayesha creating a being called "Adam" who she intends to use to destroy the Guardians. You shouldn't need us to tell you that's Adam Warlock!
In a recent chat with IGN, writer and director James Gunn confirmed that he intends on bringing Ayesha back, something we probably all expected to be the case, but it's good to know it will happen.
"I absolutely plan on bringing Elizabeth Debicki back. She’s actually one of my favourite actors I’ve ever worked with. I think on this movie between her, Pom Klementieff who plays Mantis, and Chris Sullivan who plays Taserface, they really were three of the best actors I’ve ever worked with and were all such a joy on this film to deal with that I would love to deal with them again."
It's going to be interesting to see how Ayesha and Adam factor into Guardians of the Galaxy Vol. 3, especially as the latter is best known for being a hero in the comic books. Debicki receiving more screentime will be no bad thing, of course, while Adam's introduction in the Marvel Cinematic Universe is long overdue. It's just a shame that it won't be happening in time for Avengers: Infinity War!
