A new report on the upcoming Avengers: Doomsday suggests MCU fans will be seeing a returning villain arrive for the highly anticipated movie.

What villain is teased to return in Avengers: Doomsday?

In a recent post on X, noted insider My Time to Shine seemed to hint that none other than Josh Brolin’s Thanos would be returning for Avengers: Doomsday. The insider reposted a GIF of Thanos marking the two-year anniversary of his character being “erased from existence.”

My Time to Shine didn’t say much, but simply said that “he will officially come back soon,” hinting that Marvel Studios still has plans for the iconic villain. Of course, it’s unknown exactly how Thanos will fit into Doomsday should he appear, or whether or not he’ll appear at all in the film, which is set to arrive in theaters on December 18, 2026.
