Deadpool 3 Can Fix 1 Phase 4 X-Men Insult, But There’s A Big Catch

There’s yet another X-Men mutant that Deadpool 3 can bring to the MCU, but Phase 4 already complicated his potential return. Prior to Deadpool 3, the Marvel Cinematic Universe has planted a few subtle set-ups for an eventual mutant takeover. For instance, the Maximoff twins were the only two test subjects to survive an artificial enhancement from Hydra, apparently because of their dormant abilities. Later on, Ms. Marvel revealed that Kamala Khan has a genetic mutation; and soon after, Patrick Stewart’s Professor X himself appeared as a mutant member of the Illuminati in Doctor Strange in the Multiverse of Madness.
