Rumors suggest that the Marvel Cinematic Universe may introduce Thanos’ brother, Starfox, AKA Eros of Titan, in an upcoming film.
Early casting breakdowns for the upcoming Eternals film, seemed to originally include Starfox. There were several changes to the casting as the role of Dave Whitman/Black Knight was originally being cast as a female archeologist named “Karen”. Though Eros does not seem to be appearing in The Eternals, the character is too big for the studio to throw away.
It is currently thought that he will be included in one of the cosmic projects that are planned. Starfox is often portrayed as a hero and has had major storylines in the comics with Thanos, Captain Mar-Vell, She-Hulk, and was also one of the Avengers. He also set up the team Dark /Avengers.
Having worked with so many characters, there are several places he could be introduced. Starfox could be introduced in Captain Marvel 2, Guardians of the Galaxy Vol. 3, or even the Secret Invasion project that is rumored to be in the works.
However they decide to go, an introduction of Starfox could mean huge things for the cosmic side of the MCU. As always we will keep you posted when we hear more.
