The 2005 storyline by Brian Michael Bendis and Olivier Coipel, House of M, ushered in a new era for the Avengers and X-Men, while offering ramifications still seen in today’s Marvel publications. For those out of the loop, House of M begins with Wanda Maximoff, the Scarlet Witch, mourning the loss of the mutant nation Genosha, which was destroyed in the opening salvo of Grant Morrison’s New X-Men....
Through House of Magnus, Magneto rules the world alongside his children Quicksilver, Polaris, and Scarlet Witch, who has resurrected her own children. When the former Avengers and X-Men are made aware that the reality they are living in is a lie, thanks to a young mutant named Layla Miller, they attack the House of Magnus and it’s revealed that it was Quicksilver who convinced Wanda to create this alternate reality. When Magneto, awakened to the fact that he has been manipulated, kills Quicksilver, Wanda snaps and utters the famous words “no more mutants,” and the world seemingly returns to normal, except millions of mutants all over the world suddenly find themselves without their powers.
So what would the MCU need to do in order to pull this storyline off? Just as Infinity War and Endgame were significantly different from The Infinity Gauntlet storyline, any adaptation of House of M would deviate from the comics. The key to this story working in the MCU is the Scarlet Witch. Elizabeth Olsen is certainly up to the performance requirements, but Wanda’s descent into madness is a tricky subject matter, and one that needs to happen over time. She’s already lost her brother Pietro (Aaron Taylor-Johnson) in Avengers: Age of Ultron (2015), and Vision (Paul Bettany) in Avengers: Infinity War (2018), so the door to her break from reality has been cracked open. But after taking on Thanos (Josh Brolin) in Endgame, Wanda seems to be in a decent place, at least judging by her conversation with Hawkeye (Jeremy Renner) after Tony Stark’s (Robert Downey Jr.) funeral.
Of course the upcoming Disney+ series, WandaVision, will provide a more intimate look at Wanda’s mental state. The series is rumored to showcase Wanda’s reality warping powers as she and Vision attempt to lead a normal life in pastiche of 1950s American living. If the series draws inspiration from Tom King and Gabriel Hernandez Walta’s Vision (2018) comic series, then Wanda and Vision are in for a rude awakening about normalcy. With Marvel Studios' head Kevin Feige stating that the Disney+ series will be essential to the film journeys of these characters, there’s significant groundwork for House of M that could be laid if Wanda were to lose Vision again, and any children she might have conjured up for them.
While Wanda earns her M with her last name, Maximoff, there’s no indication that she or Quicksilver have any ties to Magneto. This could easily be changed. Their Sokovian parents could have adopted them. And since Wanda and Pietro are the only examples of the mind stone granting super powers, it could easily be explained that the stone unlocked their repressed mutant genes. Creating Scarlet Witch’s connection to Magneto is the easy part, but what’s more difficult is making mutants matter within the span of 10 years. So far the MCU has no mutants, at least none that have been introduced yet. That’s likely to change soon, and given how quickly Marvel Studios brought Spider-Man into the MCU, mutants and X-Men can’t be too far off.
