After much speculation and fan theories, Agatha All Along finally confirmed Joe Locke’s character of “Teen” as none other than Billy Kaplan, a.k.a. Wiccan, also known as Billy Maximoff. Yes, he’s the son of the Scarlet Witch and the Vision from WandaVision, given a fresh new body. But as the son of Wanda and Vision, his family tree in the MCU is quite complicated. He’s related to a villainous robot and four iconic Avengers. And that’s just for starters. Here’s the MCU family lineage of Billy Maximoff (and his brother Tommy, should he ever appear). We’ll start with their great-granddads on their father’s side.
The Great-Grandfathers (Paternal Side) – Tony Stark and Bruce Banner
In Avengers: Age of Ultron, we learned that Ultron was essentially the A.I. “child” of Tony Stark and Bruce Banner. Once he became sentient, he became hellbent on destroying the world and all of its human vermin. A great deal of Tony’s personality went into Ultron’s programming, although we imagine Ultron’s tendency towards anger is part of his other daddy, Banner. So in essence, Iron Man and the Hulk count as Billy and Tommy’s great-grandfathers.
The Grandfather (Paternal Side) – Ultron
The genocidal A.I. known as Ultron came very close to destroying the world in the second Avengers film. He actually did destroy Wanda and Pietro’s home country of Sokovia. For a brief time, Ultron took the Maximoff twins under his wing until they rebelled. Although, we wouldn’t go as far as saying he’s a father figure to them. However, he is the literal father to Billy and Tommy’s dad, the Vision. But in order for his synthetic child to come to life, he ultimately needed some help from a flesh-and-blood human.
The Grandmother (Paternal Side) – Dr. Helen Choi
Dr. Helen Cho (Claudia Kim) has a relatively small role in Avengers: Age of Ultron, as the scientist who was brainwashed by Ultron (using the Mind Stone) into helping him create his synthezoid Vision. An associate of the Avengers, Ultron mind controlled her to help him complete his new android body, so we think we can safely count her as the grandmother of Billy and Tommy Maximoff.
The Great Uncle? (Paternal Side) – Thor Odinson
Yes, the Vision is technically the child of Ultron and Dr. Choi, and therefore the product of Tony Stark and Bruce Banner as well. But it was the son of Odin, the mighty Thor himself, who used his Asgardian lightning to bring the spark of life into the Vision. So, we have chosen to count him as part of the family too. At best, we’ll think of him as a “Great Uncle” of sorts? Vision would not have existed without him.
The Father – Vision
To Ultron, the living synthezoid he conceived of was someone he considered his ultimate “Vision.” However, created with a mix of the Mind Stone and J.A.R.V.I.S., Vision would not adhere to his father’s dark intentions. He committed patricide by killing the last Ultron drone on Earth. Vision, or an aspect of Vision, became the father of Billy and Tommy. This happened when Wanda brought him forth from what existed of the Mind Stone within herself. Although that Vision dissipated with the fall of Wanda’s hex, his memories live on inside his recreated android body, known as “White Vision.”
The Grandparents (Maternal Side) – Olek and Iryna Maximoff
We know very little about these two citizens of the fictional Eastern European country of Sokovia. All we know from WandaVision flashbacks is that the patriarch, Olek, loved old American sitcoms. He shared many old shows with his family, via DVD box sets. He was married to Iryna Maximoff, about whom we also know very little. Both of them were the victim of a wayward Stark missile. That their two twins, Wanda and Pietro, were the only survivors of that attack, and hellbent on revenge later. Maybe via Billy, we eventually learn more about them.
The Mother – Wanda Maximoff, the Scarlet Witch
Wanda Maximoff is the mother of Billy and Tommy, and the world’s most powerful sorceress, the Scarlet Witch (Elizabeth Olsen). Thanks to WandaVision, we know she had supernatural innate power, even before she volunteered for Hydra experiments with the Mind Stone. Once connected to the Mind Stone, she was able to access the power of all the other Infinity Stones on some level, allowing her to create a version of the Vision, as well as her twin sons within the hex. She’s currently dead, but no one believes that, right?
The Uncle – Pietro Maximoff, Quicksilver
Wanda had a twin brother with super speed powers named Pietro, abilities bestowed on him by Hydra experiments done with the Mind Stone. Technically, he’s her older brother, as he was born a few minutes ahead of her. Pietro, portrayed by Aaron Taylor-Johnson, died fighting Ultron alongside the Avengers. The twins never got to meet their uncle, however, they eventually had a very similar stand-in uncle.
The Honorary Uncle – Ralph Bohner
Agatha Harkness manipulated Wanda within her own hex in WandaVision by forcing down-on-his-luck actor Ralph Bohner (Evan Peters) to pose as a version of Wanda’s dead brother Pietro. She gave him super speed, and this “Fake Pietro” served as the only uncle the twins ever knew. This was, of course, a nod to the fact that Peters played another version of Pietro in the X-Men films. Since he was the twins’ uncle as far as they knew, on some level, he counts as family in our book.
The Kids, Billy and Tommy Maximoff
This brings us, at last, to Billy and Tommy Maximoff, the “fake” children created by Wanda within the hex. Although only existing for technically a few days, they had the mental equivalent of two ten-year-olds, give or take. Billy was born with magical powers like mom, while Tommy exhibited super speed like his uncle. Although originally dismissed as just illusions, they clearly had real souls, possibly because of Wanda having residual powers from the Soul Stone. (Or maybe thanks to Mephisto?) When the hex came down, they were thought destroyed. But as Agatha All Along has shown us, they survived.
Rebecca and Jeff Kaplan (Billy’s Parents 2.0)
As we know from Agatha All Along, Billy Maximoff took over the deceased body of one William Kaplan, a citizen of Eastview, New Jersey. But 13-year-old William Kaplan had biological parents, Rebecca and Jeff Kaplan who are still raising him as their own. So they have to count as Billy’s parental figures as well. We saw them portrayed by actors Maria Dizzia and Paul Adelstein in the sixth episode of Agatha All Along.
All in all, Billy Maximoff has the most complex family tree in all of the MCU. But that’s nothing compared to his family lineage in the pages of Marvel Comics. There, we have to include Ant-Man (Ultron’s creator in the comics), Wonder Man (Vision’s brother), Vision’s android family, and Magneto and his entire clan as well. But who knows? In a few years, Wiccan’s family tree in the MCU might be just as complex.
