A newly recruited Avenger who initially allies with Ultron, and the twin brother of the Scarlet Witch, who can move at superhuman speed. About the character Taylor-Johnson said, "Him [sic] and his sister [Scarlet Witch] have been abandoned by their parents and their father, and they grew up in Eastern Europe defending and looking out for themselves and each other... His sister really is his guidance - emotionally she's the one who looks after him, and vice versa. He's very overprotective physically - he doesn't want anyone touching her." Taylor-Johnson also said that Quicksilver has "real anger frustration" and is easily bored due to a short attention span.
