Scarlet Witch

The Scarlet Witch is a mutant who was born Wanda Maximoff and is the daughter of Magneto and the twin sister of Quicksilver.

Wanda and her brother Pietro grew up not knowing their father, for he had abandoned them after his wife ran away, and put them in the care of gypsies. Both Wanda and Pietro joined their father's group of villains, the Brotherhood of Evil Mutants, but still did not know who Magneto was to them.

Eventually, they disbanded from the Brotherhood and reformed, joining the Avengers. Sometime later, Scarlet Witch's powers of chaos went out of control, and she was driven insane. Her brother Quicksilver used this to his advantage and tried using her to take over the world. She was eventually released from her insanity and joined the Avengers again.
