"The Marvels: A Cosmic Twist in the MCU's Road to Ruin"

The post-credits scene in "The Marvels" introduces an incursion event, a long-teased multiversal calamity that will play a critical part in the future of the MCU and its Multiverse Saga. The scene features a cameo by Kelsey Grammer as Beast, hinting at the integration of the Fox X-Men franchise into the MCU. This sets the stage for upcoming films like "Deadpool 3" and the potential inclusion of characters like Professor X. The MCU's next phase is likely to draw inspiration from the comic-book crossover event "Secret Wars," where the collision of different Marvel universes creates a new reality. The Multiverse Saga is expected to intensify as the release of "Secret Wars" approaches.
