Deadpool 3

The MCU is currently exploring its Multiverse Saga, which has seen both the introduction of new heroes that are not part of the main MCU Earth — such as John Krasinski's Reed Richards and Anson Mount's Black Bolt — as well as variants from beloved MCU heroes, namely Andrew Garfield and Tobey Maguire's versions of Spider-Man, as well as Sophia Di Martino's Sylvie, the female Loki. Corrin could play the multiverse villain Lady Deadpool in Deadpool 3. If Lady Deadpool were to ever be introduced in the MCU, there would never be a more fitting time to do so than in the middle of the Multiverse Saga with Deadpool 3
