10 Recent Plot Twists That Changed Movie Franchises Forever
5. Thanos' Brother - Eternals
In the MCU, Eternals are an ancient race of aliens forged by cosmic beings to safeguard humanity. Even though most comic fans are aware the Eternals are related to Thanos' species, the Titans, this detail is mostly ignored in the movie.
However, all that changes in the post-credits scene. In the film's stinger, the Eternals are soaring through space in their ship before being interrupted by Pip the troll and Thanos' brother, Eros, teleporting in front of them. The Eternals are frightened at first, but Eros reassures them that he's there to help.
Although the Marvel Cinematic Universe has introduced many new characters in 2021, Eros' addition is sure to have major implications. In the comics, Eros is an intergalactic superhero, a Sh'iar delegator, and an Avenger. Because his adventures take place across the cosmos, he could appear in future films related to the Eternals or the Guardians of the Galaxy. He is sure to divulge some valuable knowledge about his infamous sibling, as well as what came of his race.
And who knows? If Eros is still alive, we might see Thanos father, Mentor, or his mother, Sui-San, in the MCU's future.
