The Marvels' nod to a famous Marvel Comics storyline teases the MCU's Norman Osborn potentially starring in Thor 5. The Marvel Cinematic Universe is a behemoth of a franchise, filled with hundreds of characters and multiple parallel storylines. While most upcoming MCU movies and shows are building up to Avengers: The Kang Dynasty and Avengers: Secret Wars, some of them are also setting up other stories and comic book adaptations that give certain MCU characters their time in the spotlight. For instance, The Marvels' ending scene sets up the Young Avengers, and multiple Phase 4 and 5 movies and shows teased the titular team's first mission together in 2025's Thunderbolts.
