Adam Warlock’s shadow has been looming over the Marvel Cinematic Universe ever since James Gunn introduced the character inGuardians of the Galaxy 2. It is expected that Adam, who is a big part of theInfinity Warcomics, will have a large part to play in the future of the MCU, but will he be further introduced inAvengers: Endgame? A new theory suggests that he and Vision might have a pretty big role to play in the movie and how it sets up Phase 4 of the MCU.

Infinity WarseesVisiongo through quite a bit, but we also learned that he and the Mind Stone were evolving. Thanos and his Black Order are coming for the Infinity Stones and Vision wants to remove and destroy the Mind Stone, in an effort to keep Thanos from achieving his goal. While inWakandaand deciding whether or not taking the stone out of his head will kill him, Bruce Banner explains that there’s a good chance that Vision with survive. He explains.

“Your mind is made up of a complex construct of overlays. JARVIS,Ultron, Tony, me, the Stone. All of them mixed together, all of them learning from one another… if we take out the Stone, there’s still a whole lot of Vision left. Perhaps the best parts.”

With that being said, there have been more than a few theories that state Vision is taking on theAdam Warlockstoryline for the MCU. However, this could also mean that Infinity Stones are able to be given to other characters to take on their soul, much like what Warlock did in the comics. Warlock has the Soul Stone embedded in his head and then collects the scattered stones to hand them out to the right souls, allowing them to, “lead their own individual lives. Write their own destinies.”

This could mean that the Infinity Stones going forth afterAvengers: Endgameare all living entities while bringing Adam Warlock into the MCU. There are some problems with this theory. For one, theRusso Brothers claim that Warlock will not be in Endgamebecause they don’t want to do a direct adaptation of the comic book source material, which makes complete sense. However, a lot has changed, especially withGuardians of the Galaxy 3being on hold.

Additionally, the Russo Brothers have been known to throw out some misdirects. For instance,Avengers: Endgamewas guessed as the title pretty much right away, but the directing duo shot it down and said that the title was not uttered duringInfinity War. Obviously, they couldn’t come out and say that at the time, it would’ve blown the whole secret. They might be doing the same thing with Adam Warlock inAvengers: Endgame, we’ll just have to wait and see. This fan theory was originally presented byScreen Rant.
