In Marvel Rivals, mutants are characters who possess the X-Gene, granting them extraordinary abilities. The playable mutant heroes in the game include:

• Emma Frost (Vanguard)
• Magik (Duelist)
• Magneto (Vanguard)
• Namor (Duelist)
• Psylocke (Duelist)
• Storm (Duelist)
• Wolverine (Duelist)

These mutants come from the Marvel universe's X-Men and related storylines, each offering unique playstyles and abilities. For example, Emma Frost can tank damage with a diamond shield, Psylocke excels at mobility and crowd control, and Wolverine is a durable melee fighter with healing abilities. Namor, while a mutant hybrid, brings strong area control and durability to the battlefield. Magneto and Storm provide powerful control and elemental abilities, respectively, and Magik can summon minions and disrupt enemies with her portal to Limbo

. Thus, mutants in Marvel Rivals are a key faction of heroes defined by their genetic mutation powers, making them distinct from other groups like Avengers or Guardians in the game
