The Mutants are the genetic descendants of both humans and Xiliens. They were trained as a form of highly elite soldiers by the EDF under instructor Kumasaka. In Godzilla: Final Wars, they fought the Xiliens. The most notable Mutant is Ozaki, who gave up his Keizer Energy to revive Godzilla.
The Mutants possess multiple abilities, including super strength, enhanced verticality, and enhanced reflexes, aiding them in combat.
