Scarlet Witch appeared in 1964 Marvel Comics called X-Men.
Wanda Maximoff, the Scarlet Witch, is a Romani sorceress and twin sister of the speedster Quicksilver. Once believed to have been mutant children of Magneto, the twins are in truth orphans enhanced by the High Evolutionary at Mount Wundagore in Transia. The Scarlet Witch became a conduit of chaos magic, allowing her to shift probabilities and warp reality itself by casting various "hexes". After being saved from an angry mob by Magneto, the Scarlet Witch and her brother joined the Brotherhood of Evil Mutants to fight for Magneto's mutant supremacy cause. Disagreeing with Magneto's ruthless approach to human hostilities towards mutants, the twins left him and joined the super-heroic Avengers instead.
The Scarlet Witch was trained by Agatha Harkness to explore her naturally powerful magical abilities. She also had in the demon lord of chaos Chthon an archnemesis. As an Avenger, Maximoff fell in love with and married her synthezoid teammate, the Vision. In order to have a family with her artificial husband, she used her abilities to conceive two twin boys, but the spell was later broken, erasing both boys from existence, a tragedy that was accompanied by her husband being dismantled. The trauma of losing her family made her mentally vulnerable. After she attacked the Avengers twice, the group disassembled. Subsequently, in a major, erratic display of her powers, the Scarlet Witch reshaped reality under the rule of the House of M, based on Magneto's wishes. As the Avengers and the X-Men battled to restore reality, she uttered the words "No More Mutants", wiping out the super-abilities of most mutants in retaliation to Magneto's extremism. This action became known as the mutant decimation.
For years, after a long way to rejoin the Avengers, the Scarlet Witch has been haunted by her actions in a journey for redemption, which culminated in the creation of the Waiting Room to revive lost mutants. More recently, she found herself dealing with the threat of Chthon once again by getting into contact with his cursed tome, the Darkhold. Moreover, she currently runs the Emporium, a witchcraft shop aimed at assisting those in need of help.
