Marvel Studios may have finally teased the answer to a seven-year-oldMCUmystery inWhat If…?season 3, which could have major implications for the upcomingIronheartseries. While previous seasons of Marvel Animation’sWhat If…?included only heroes who had already appeared in the MCU’s live-action projects,What If…?season 3 marked the debut of several characterswho hadn’t yet appeared in the MCU. One of these new additions perfectly sets the stage for an upcoming MCU series, and could have also solved an annoying Phase 3 mystery.
Among some of the new additions to the MCU inWhat If…?season 3, the most recent chapter of the animated Multiverse Saga series also featured a number of returning characters. This sawWhat If…?introduce variants of Sam Wilson’s Captain America, Agatha Harkness, Riri Williams' Ironheart, Shang-Chi and Kate Bishop, among others.The latter two appeared as outlaws in the Wild West of 1872 searching for Shang-Chi’s missing sister, Xu Xialing, which brought them across a villain that hasn’t been seen in the MCU since 2018’sAnt-Man and the Wasp.

Sonny Burch Working For The MCU’s Hood Changes The Ant-Man & The Wasp Villain
In Marvel Comics, young criminal Parker Robbins becomes the hood after stealing the cloak and boots from a demon he had just killed. It’s possible Marvel Studios could follow a similar storyline for Anthony Ramos' Parker Robbins, though there has been speculation that theHood’s demonic connection will actually be to Mephisto.If Mephisto is the man behind the curtain of both the Hood and Sonny Burch, theAnt-Man and the Waspvillain’s motivation could be viewed very differently, as he might truly be fighting for his life.
Parker Robbins' Hood made his first Marvel Comics appearance in 2002’sThe Hood #1, and he went on to become one of New York’s most powerful and notorious crime bosses.

Little was revealed about Sonny Burch’s history inAnt-Man and the Wasp, only that he was a master at traversing the black market, and his unidentified boss took an interest in quantum technology.

This could all come to a head soon, as Marvel Studios has already teasedMephisto’s debut in the MCU.
