The Scarlet Witch is a fictional character appearing in American comic books published by Marvel Comics. The character was created by writer Stan Lee and artist Jack Kirby. Her first appearance was in The X-Men #4 in the Silver Age of Comic Books. Originally said to have the ability to alter probability, the Scarlet Witch has been depicted as a powerful sorceress since the 1980s and was later said to be powerful enough to alter reality. For most of her comic book history, she is portrayed as a mutant, a member of a fictional subspecies of humans born with an "X-gene" that grants superhuman abilities and traits. This was revised via a 2015 storyline establishing that her superhuman traits are a result of experimentation done by High Evolutionary when she was a child.
