Heartbreaking Avengers: Doomsday Theory Has Thor And Loki Die In Their MCU Movie Reunion

Avengers: Doomsday will likely mark the Marvel Cinematic Universe reunion of Thor and Loki, but the film could end tragically for the brothers, as both of them could die when all is said and done. Chris Hemsworth's Thor has had to watch his brother die twice. The first time happened in Thor: The Dark World, which was only Loki faking his death. Tom Hiddleston's God of Mischief later died for real in one of the MCU's best movies, Avengers: Infinity War, and Thor could do nothing against Thanos.
