We’re about a year out from the release of the Avengers 4, yet we know very little about the upcoming film. Thanks to a new report from MCUCosmic, however, we now have details about the role Hawkeye, Captain Marvel, and an alien race known as Skrulls.

Apparently, a small part of the film will deal with Hawkeye, who may take on the role of Ronin. He’ll allegedly find himself in Japan hunting down Yakuza. Only, this won’t be the ordinary Yakuza; they’ll be Skrulls, a race of shape shifting aliens who play a big role in Captain Marvel’s storyline.

Here’s what MCUCosmic had to say:

In the post-credits scene of Avengers: Infinity War, Nick Fury and Maria Hill are tracking the extraterrestrial signals being detected in Wakanda. Now neither Fury nor Hill knows about Thanos coming to Earth. But Fury does know about another extraterrestrial threat in the Skrulls due to him being around Carol Danvers in the ‘90s when she was dealing with them. That’s why he sends the signal to Captain Marvel, because he believes the Skrulls were finally invading Earth.

A primary plot point of the upcoming Captain Marvel movie is said to focus on the Kree-Skrull war, which occurs before Thanos eliminates half the universe. Captain Marvel’s movie, if you remember, is said to take place in the ‘90s, well before the events in Avengers: Infinity War.

MCUCosmic claims the Skrulls will have only a small role in Avengers 4, but it will be what draws Captain Marvel back to Earth, where she will ultimately help undue the damage done by Thanos in Avengers: Infinity War. The introduction of the Skrulls may also lay the groundwork for a larger invasion as Phase 4 of the Marvel Cinematic Universe develops.

Avengers 4 is set to hit theaters on May 3, 2019.
