Mystique is a shape-shifting mutant from Marvel Comics known for her cunning, ruthlessness, and ambiguous allegiance. She was created by writer Chris Claremont and artist Dave Cockrum and first appeared in Ms. Marvel #16 in 1978.

Mystique's true name and past are shrouded in mystery, but she is known to have been born a mutant with the power to alter her physical appearance and voice to resemble any person, including their clothing and mannerisms. Her shape-shifting abilities make her a skilled spy and infiltrator, and she has used her powers for both criminal and heroic purposes.

Mystique has been a member of several groups, including the Brotherhood of Evil Mutants, the Freedom Force, and the X-Men. Her relationships with other mutants have been complex, including romantic entanglements with Sabretooth and Destiny, and motherhood to the mutant Rogue.

Mystique's most notable appearances include her role as the main antagonist in the X-Men film franchise, portrayed by actress Rebecca Romijn and later by Jennifer Lawrence. She has also appeared in various animated series and video games.
