Casting characters for the first film of the X-Men franchise in the MCU.
The Mutants / Rise of the Mutants / Genesis of the Mutants / Mutant Genesis
The X-Gene is present in everyone, but it is very rare for it to be triggered. The four snaps of the Infinity Gauntlet and the power of the Infinity Stones caused some of the people affected to have their X-Genes activated. Some people, however, have had their X-Genes activated without the use of Infinity Stones. These people include Wolverine, Magneto, Scarlet Witch, Apocalypse, Exodus, Namor the Sub-Mariner, Professor X, Ursa Major, Darkstar, the members of Alpha Flight, and more.
The movie will end with the main characters of this film being met by Professor X to bring them to the Xavier Institute for Gifted Children.
