Summary
- Marvel Studios may introduce a powerful multiversal villain in Thor 5, connecting to Loki season 2 and the Fantastic Four reboot.
- The villain, Black Winter, threatens the multiverse in Marvel Comics, so could infect the MCU's new multiversal Yggdrasil, putting both Thor and Loki at risk.
- Thor 5 is suspected to have a darker tone, and the debut of the Black Winter and the potential return of past MCU villains would help to make the as-yet-unconfirmed project the most intense MCU installment yet.
