Maximoff is an enhanced individual, after having been forced to be a test subject on and receiving hypnotic and telekinetic abilities. Her twin brother, Peitro (Quicksilver), was also tested on and given super speed. Their captor, Baron Wolfgang von Strucker, kept them locked up in Sokovia, until the Avengers stormed his base, inadvertently setting them free. They were then mislead by Ultron into taking down the Avengers with him, but Wanda read his mind (when he was downloading himself to a new body with the Mind Stone attached) and discovered that he planned to eradicate humanity.
The twins turned against him and joined the battle with the Avengers at Sokovia, where Ultron planned to use a vibranium machine to cause global extinction. In the battle, Pietro died. In the aftermath, Maximoff was officially recruited into the Avengers.
In the credits and comics, Maximoff is referred to as Scarlet Witch, although she is never referred to by this name by any other character or anywhere else on-screen. However, the upcoming limited series WandaVision, is planning to explore how she becomes known as the Scarlet Witch within the MCU.
