You can forget about Adam Warlock appearing in the untitled sequel, Avengers 4, to save “Earth’s Mightiest Heroes” and the universe.
The powerful character has a long history of being associated with the Infinity Stones in the comic books, and also played a crucial role in undoing the cosmic damage incurred at the hands of Thanos. Hence, there have been several fan-crafted theories about his possible venture in the Marvel Cinematic Universe.
Speaking with ComicBook in a recent interview, co-director Joe Russo finally confirmed that Adam Warlock will have nothing to do in Avengers 4. The heroes that survived in Avengers: Infinity War will have to deal with the gloomy situation themselves. They will surely have some outside help, such as from Captain Marvel, but not from this particular character.
“Yeah [Adam Warlock]’s not showing up in our stories. Look, our job as we said a million times is to tell the story of the Marvel Cinematic Universe, not to do direct adaptations of the comics because we’re comic book fans,” said Russo. “I have no interest as a director in telling a story that’s already been told or in seeing one that’s already been told. If I know all the events story as they’re going to happen then what’s the point of going to the film? We want to keep surprising audiences and continue the story that started with Iron Man […] a decade ago.”
That being said, Adam Warlock was originally intended to appear in Avengers: Infinity War. The character, though, had to be removed because it was felt by the screenwriters that he needed his own solo debut before making such a massive appearance in an important event in the timeline.
Guardians of the Galaxy Vol. 2 (2017) saw the Sovereign, a highly advanced and genetically engineered galactic race seeking to perfect themselves, create Adam Warlock to serve as a mighty weapon. The character has only been teased for the time being and is expected to make his debut in Guardians of the Galaxy Vol. 3 (2020) in some capacity.
Avengers: Infinity War is now running in theaters worldwide and will open in China on May 11. The untitled sequel, presently dubbed Avengers 4, is slated to premiere on May 3, 2019.
