Wanda and Pietro were born in Wundagore inside the dungeon of the mountain of Chton to Magneto and Magda. Magda and her children fled, but Chton formed a bond with Wanda, making her a Earth's dimensional energy, adding the ability to cast spells to her mutant abilities.
Then they grew up with gypsies Django and Marya Maximoff. Later, the camp was attacked, the two were forced to flee and joined Magneto. Magneto sent them at Wolverine and Sabretooth. They convinced them that Magneto was evil and he invaded the camp to get them back. When Magneto disappeared, they both left Magneto's team and joined Fury, Hawkeye became their partner.
Wanda took lessons from Agatha Harkness to learn magic.
Thanks to her abilities, she improved the morale of the team, learned to treat and heal any injuries and diseases, and how inflict diseases on enemies. Quicksilver convinced her to create a utopian alternate reality where all the heroes' wishes would come true. Humanity became minority and mutants led by Magneto are the rulers of the world, everyone was happy.
Sensible Layla Miller, saw through the illusion, restored memories of most of the heroes, when they all realized what Quicksilver had done, Magneto charged and killed him, Wanda revived him and in a rage said three fateful words: No more mutants, thereby depriving 90% of mutants of their abilities. Wanda disappeared soon after and was presumed dead for a long time. This day went down in history as M-Day - the mutant genocide.
