One Marvel Comics event would be perfect to allow Thor 5 to fit Chris Hemsworth's condition for returning as the God of Thunder, and would set up a huge crossover event in the MCU. Chris Hemsworth is currently the only MCU hero to receive four solo projects, comprising 2011's Thor, 2013's Thor: The Dark World, 2017's Thor: Ragnarok, and 2022's Thor: Love and Thunder. While Thor's adventures haven't always been positively received, with Love and Thunder receiving a great deal of criticism, there is speculation that Marvel Studios will be developing Thor 5. While Thor 5 hasn't yet been officially confirmed, the project will need to make some serious changes.
