Billy Maximoff

"My head feels weird. It's, like, really noisy. I don't like it."

- Billy Maximoff to Wanda Maximoff

William "Billy" Maximoff was the son of Wanda Maximoff and Vision, and the twin brother of Tommy Maximoff.

Unexpected Arrival
"There's another baby coming!" "Billy?!"

- Vision and Wanda Maximoff

After an unnaturally fast pregnancy, Billy Maximoff was born shortly after his twin brother Tommy to their parents, Wanda Maximoff and Vision, in their Westview family home. After being checked over by Dr. Stan Nielson, the new-born twins were but to bed as Wanda and Geraldine watched over them. After reminiscing about her own twin brother, their mother sung them a Sokovian Lullaby to get them to settle. When she recognised the name 'Pietro', Geraldine (really Monica Rambeau) enquired about Wanda's history with Ultron and disrupted her fantasy. Becoming more and more aggravated, Wanda interrogated Geraldine about how she knows Pietro. In response to the adults' confrontation, Billy and Tommy started to cry until Wanda used her powers to eject Geraldine from Westview. Billy and his brother calmed down again once Wanda returned to them.

Personality
Billy Maximoff is considered the more "dorky" twin, according to Tommy Maximoff. Maximoff seems to be interested in Halloween, calling it a "magical holiday" and mentioning that it is full of family, friends, and dressing up as someone else. He is also the only twin to have a costume prepared ahead of time. Conversations with his brother hint that he is intelligent. Maximoff is also shown to be concerned about his mother when she seemed to be especially depressed.
