Two characters from The Eternals may be introduced in Avengers 4. Marvel Studios is looking to close out Phase 3 of the Marvel Cinematic Universe in style next year with the follow-up to Avengers: Infinity War, but, as focused as they are on concluding their first saga, they're also looking to build towards the future.
Marvel is being extremely quiet when it comes to officially talking about what comes after Avengers 4. The only movie that is confirmed by the studios is Spider-Man: Far From Home, which picks up minutes after Avengers 4. The reason for the secrecy is partially to protect the secrets of the highly anticipated blockbuster. However, other reports have made it clear what properties are becoming priorities for them. One of these potential cornerstones of the MCU may be The Eternals, even though most have never heard of them. That said, it appears that Marvel will help familiarize audiences with characters from The Eternals as early as Avengers 4.
DanielRPK, of SuperBroMovies, shared some news on how Marvel plans to introduce the Eternals, and it appears that they will make their debut in an upcoming film. He explains that the reason The Eternals is currently casting (as indicated by character breakdowns for the movie) is to get at least some of its cast members on board for possible on-screen appearance as early as next year. He believes that the two Eternals characters are Karen and Piper, who audiences may see turn up in Avengers 4.
The two Eternals are "Karen" and Piper/Sprite. They will most likely show up in a cosmic Marvel movie so either Captain Marvel or Avengers 4. A4 is more likely.— Daniel R (@DanielRPK) November 24, 2018
As of now, this news is strictly a rumor mixed with speculation, so fans should treat this as such. However, if Karen and Piper are, in fact, being cast right now, it's also possible that they could show up even earlier in Captain Marvel - which is all the more likely given that the Eternals have links to the Kree and Skrull alien races. Whether they show up in the movie itself or during a mid-credit/post-credit sequence, it would signal to audiences that the entire roster of The Eternals will have major roles moving forward. That said, their introduction in Avengers 4 would make it a curious decision to then set the movie "millions of years ago," as a possible synopsis suggested.
The identity of "Karen" is still a mystery that has yet to be solved, but her identity may come to light fairly soon - assuming these rumors turn out to be true. She was described as a powerful, but warm leader, so being a major force among the Eternals would make sense as to why she'd be one of the first to appear. Piper, on the other hand, is believed to be an alias for a gender-swapped version of Sprite, a character who has had major roles in some Eternals comics. If this is all true, then it shouldn't be too much longer before both characters are cast in time for Avengers 4's release.
