Thor shockingly dies in Marvel Studios' last release of 2025, and Chris Hemsworth's God of Thunder could do it again in 2026's Avengers: Doomsday.
The MCU has introduced many powerful alien characters, although some of them find it hard to emerge from Thor's shadow.
Avengers: Doomsday's potential source material, the prelude to Secret Wars, may spoil Thor's story in the MCU's upcoming Phase 6 movie.
