He is the son of Wanda Maximoff, also known as the Scarlet Witch, and Vision, and the twin brother of Billy Maximoff.

As he grows older, he is depicted with a more rebellious, confident style that matches his adventurous nature. Tommy possesses superhuman speed, allowing him to run and move at incredible velocities, making him similar to his uncle, Pietro Maximoff, also known as Quicksilver.
