Wanda Maximoff, the Scarlet Witch, is a Romani witch and twin sister of the speedster Quicksilver.[5][32][3] Once believed to have been mutant children of Magneto,[33] 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".[8][23] 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.[5] Disagreeing with Magneto's ruthless approach to human hostilities towards mutants, the twins left him and joined the super-heroic Avengers instead.[34] The Scarlet Witch was trained by Agatha Harkness to explore her naturally powerful magical abilities.[35] She also had in the demon lord of chaos Chthon an archnemesis.[36] As an Avenger, Maximoff fell in love with and married her synthezoid teammate, the Vision.[37] In order to have a family with her artificial husband, she used her abilities to conceive two twin boys,[38] but the spell was later broken, erasing both boys from existence,[39] a tragedy that was accompanied by her husband being dismantled.[40] The trauma of losing her family made her mentally vulnerable. After she attacked the Avengers twice, the group disassembled.[41][42] 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.[43] 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.[44] For years, after a long way to rejoin the Avengers, the Scarlet Witch has been haunted by her actions in a journey for redemption,[22][45][46][47][48] which culminated in the creation of the Waiting Room to revive lost mutants.[9] More recently, she found herself dealing with the threat of Chthon once again by getting into contact with his cursed tome, the Darkhold.[49] Moreover, she currently runs the Emporium, a witchcraft shop aimed at assisting those in need of help,[50] and is also a main member of a new Avengers team.[51]
