Scarlet Witch's moral complexity hints at a potential villainous turn and teases conflicts in upcoming MCU films.

Vision may be the most interesting upcoming project in the Marvel Cinematic Universe for fans of Elizabeth Olsen's Scarlet Witch and Wanda Vision, and a recent casting call for the project seems to up the ante for the character and the MCU at large.

Vision has been on the books at Marvel Studios since the title character left the franchise at the end of the Disney+ series Wanda vision. While there has long been interest in finding out what Vision had been up to since he was last seen, the project has since been much more about what it can bring to the franchise than the fate of the character. One of the more exciting prospects fans are looking forward to is the return of Olsen's Scarlet Witch, a return that has been hotly debated by insiders and fans and has speculation ranging from a techno-organic resurrection to another villainous run. The only common thread is that no matter what capacity she appears in, her return to the MCU will come in Vision is not the end of her MCU story.

Venom: The Last Dance's Rotten Tomatoes score continues a trend for Sony's Spider-Man Universe, but will this film avoid Madame Web's fate?

While James Spader's Ultron also seems ready to make a splash Vision series, recent developments in the MCU seem to suggest that Wanda will indeed be the real winner when it comes to new developments in the franchise. According to in-the-know source Daniel Richtman, Marvel Studios is looking for a young teen star to take on a co-lead role in the upcoming Vision series. While this news is interesting enough in itself, it takes on much greater significance when the events of Agatha All Along is added to the mixture.

As Vision, Agatha All Along is a spinoff of Wanda vision and is related to the events of that series. The show recently revealed that its mysterious teenage boy character was actually Billy Maximoff all along, better known to some comic fans as Wiccan, son of the Scarlet Witch. Agatha All Along explains William Kaplan's complex transmogrification into Billy, showing his ascension to his powers and potential motivations that will drive him throughout the MCU story. Considering the source material and the events already seen in Wanda Vision, it is very likely that the teenage character will get a role in Vision series is Wanda's second son, Tommy.

Tommy has been a cartoon character alongside his brother for quite some time, under the name Speed and sharing a powerset with his uncle, Quicksilver. The revelation of Billy's identity on Agatha All Along fans immediately wondered where Tommy could currently be in the MCU and even where the two kids and their mother could be headed. For the latter, there are several plot points and arcs from the comics that could be headed to the live-action series. One of the more prominent possibilities is the introduction of the Young Avengers to the MCU, as both Billy and Tommy are key members of the team in their superhero alter-egos Wiccan and Speed, respectively. More exciting is the potential for the Wiccan tone to kick off the events of the comic book arc Avengers: The Children's Crusade, which sees the character on his way to find his mother as his powers spiral out of control.

The general layout of powers in the MCU, as it stands, means that, for better or for worse, Scarlet Witch's return shouldn't be as a hero. With her children potentially coming into their own and other forces in the franchise coming together for yet another massive conflict, there's a lot to be gained by having Wanda actually explore the moral complexity that informed her actions in Doctor Strange in the Multiverse of Madness.

The MCUs Vision the series is currently set to be released to stream on Disney+ in 2026, while Wanda vision and Agatha All Along are already available on the platform.
