When Marvel Studios confirmed thatAnt-Man and the Wasp: Quantumaniawould be the official title for the film series' third installment, it initiated a whole new wave of speculation among curious fans. Now, a rumor that could have significant implications on the MCU’s future is a new casting call that allegedly seeks to fill another major role inQuantumania.

“Quantumania” clearly indicates the involvement of the Quantum Realm in the film’s plot, which has been a key element in previous storylines involving time travel. That detail, along with the fact thatQuantumaniawill reportedly be thefirst MCU film to feature Kang the Conqueror(who is a time-traveling entity), could hint at a massive multiverse plot with all sorts of unexpected surprises. However, Kang may not be the only newcomer who will shake up the MCU. According to Murphy’s Multiverse, the third film’s production team is looking to bring on a “young female of any ethnicity” between 9 and 12 years old to play an “unnamed lead character” alongside Paul Rudd’s Ant-Man and Evangeline Lilly’s Wasp.

The report also notes that the mystery character is not likely to be a younger version ofKathryn Newton’s Cassie Langsince Abby Ryder Fortson, the original child actor who played a budding Cassie Lang in the previousAnt-Manfilms, would technically qualify for the casting. The prevailing theory among fans is thatAnt-Man 3seeks to introduce a brand new superhero this time around. But who could this mystery character be? Well, since the casting call also mentions that they are looking to hire someone with “singing, dancing, and comedic chops,” some people believe it will bethe fan-favorite mutant Dazzlerfrom the comic books, who can produce light shows, holograms, and hard-light constructs.

Dazzler is all about putting on a show, so her personality matches the casting call’s description perfectly. Additionally, given that Dazzler is a mutant, there could a chance thatQuantumaniawill feature an X-Men crossover of some sort, should she end up being the mystery character. Of course, such a theory is just speculation at this point since nothing has been confirmed as of yet.

IfQuantumaniadoes introduce Dazzler, it wouldn’t the first time the MCU introduced potential new characters as children. Fans will recall that inWandaVision,Wanda Maximoff’s twin boys Billy and Tommymade their MCU debut, and according to the comic books, such characters should go on to become Wiccan and Speed, likely as part of the Young Avengers.

Marvel Studios President Kevin Feige has not ruled out the possibility ofintroducing the Young Avengers to the MCU. However, no newAvengersprojects of any kind have been added to Marvel Studio’s release calendar at this time.

Ant-Man and the Wasp: Quantumaniais scheduled for theatrical release on Jul 26, 2025.
