Three years after Eternals, Harry Styles’ Eros a.k.a. Starfox appears for the first time in an MCU project, but this time played by a new actor. Eternals introduced more than a dozen characters early in the MCU’s Multiverse Saga, including the ten titular heroes, the Deviants, and the Celestials. Eternals’ post-credits scene also featured the MCU debut of two eccentric heroes: Harry Styles’ Eternal hero Starfox and Patton Oswalt’s mystical creature Pip the Troll, who meet Makkari, Druig, and Thena as they leave Earth in their mothership.

Starfox confessed to his fellow Eternals that he knows where the rest of their kind are located, teasing the eventual introduction of many more Eternals. However, none of the projects in the MCU’s Multiverse Saga slate seem to be continuing Eternals‘ story. If Marvel Studios plans to reveal what happened to any of the Eternals, it seems like Avengers: Secret Wars will be the soonest any of them can return — at least six years after their debut. In the meantime, Marvel’s What If…? is bringing back Starfox, though not like audiences remember him.

Marvel’s: What If Experience Has Starfox’s First MCU Appearance Since Eternals

Starfox Has Been Recast For What If…? – An Immersive Story

Marvel’s What If…? – An Immersive Story, exclusively released on Apple Vision Pro, features Starfox’s return in an alternate universe where Thanos is captured before he can attack Xandar. In this alternate timeline, Thanos seeks to steal the Reality Stone instead of the Power Stone, but he’s stopped by and judged by the Xandarian authorities, including a Carol Danvers variant who works for the Nova Corps. During Thanos’ trial, his brother Eros a.k.a. Starfox seemingly tries to use his psychic influence abilities while representing him, but Thanos escapes before a decision is made.

What If…?’s Voice Cast Isn’t Expected To Replace Their Characters’ Live-Action Counterparts

Harry Styles began building his filmography in 2017 with Christopher Nolan’s Dunkirk, which opened the doors for high-profile acting credits in Chloé Zhao’s Eternals in 2021, as well as Olivia Wilde’s Don’t Worry Darling and Michael Grandage’s My Policeman in 2022. However, Don’t Worry Darling‘s mixed reception and various behind-the-scenes controversies during its production may have turned Styles off acting for a while, as the award-winning musician hasn’t participated in any film production since then. Harry Styles may be taking a break from artistic projects from now, including any possible involvement in MCU projects.

Although the wait for another Starfox appearance has been long, Harry Styles’ absence in What If…? – An Immersive Story isn’t too surprising. Marvel’s What If…? seasons 1 and 2 have recast several actors exclusively for the anthology series. For instance, Mick Wingert voiced Tony Stark, Josh Keaton voiced Steve Rogers, and Lake Bell voiced Natasha Romanoff. If Starfox ever returns in live-action, Marvel Studios will likely get in touch with Harry Styles. Until then, Thanos’ brother could keep popping up in animated projects like What If…? season 3 and Marvel Zombies.
