Spoilers for Guardians of the Galaxy Vol. 2 follow.
Guardians of the Galaxy Vol. 2 introduced a number of characters to the Marvel Cinematic Universe, most of which had their own arch in within the film. However, Ayesha and her Sovereign did not appear to be incredibly important in their MCU debut.
In fact, writer/director James Gunn admits the group and its leader were introduced solely as a driving force of Guardians of the Galaxy Vol. 2's story. Gunn took to Facebook for a live Q&A with fans where he addressed the golden race.
"It was just about the story," Gunn said. "We needed to have a pushing force, was is the Sovereign, because really the thing about Guardians of the Galaxy Vol. 2 is its really and independent film in the body of a spectacle film.
"Creating this film that was so character oriented," Gunn said. "I needed to focus on that, so I needed to have some exterior force that was pushing us forward at least a little bit into the adventure, and that is what Elizabeth Debicki as Ayesha, who I love, that's her purpose."
Though the Sovereign may have played a minor supporting role in Guardians of the Galaxy Vol. 2, they're impact on the Marvel Cinematic Universe is only just beginning. By the end of the film, Ayesha had created one of the most powerful beings in the entire Marvel Universe: Adam Warlock.
As the story goes, Adam Warlock was originally going to be included in Guardians of the Galaxy Vol. 2.
"I also do love the character of Adam Warlock," Gunn said. "In my original draft of the movie, Adam Warlock was a major character. I ended up taking out Adam Warlock because there were simply too many characters. As I said, I need each character to have their own specific story that ws important to the plot and when I added one extra major character like that it was just too many.
For Guardians of the Galaxy Vol. 3, the yet-to-be-cast Adam Warlock will likely fulfill that major role and then some. In Marvel Comics, Warlock has aligned himself on both sides of the hero and villain fence. It is possible he will jump from one side to the other within the same film as Ayesha attempts to carry out her vendetta against the Guardians to avenge her stolen anulax batteries.
Furthermore, the question of why Nebula needed anulax batteries in the first place remains unanswered. Gamora's sister landed herself among the Sovereign as a prisoner after being caught attempting to steal their valuable batteries. While we know these batteries can be quite powerful, it would appear Nebula has a plan which requires their power. Whether or not she can fulfill these plans without the assistance of the Sovereign is to be seen when the Guardians assemble after the Infinity War saga.
