While not an original Marvel superhero, of course, (hey, neither is Thor), the Marvel version of the Greek-Roman god is one of the publisher’s oldest characters, a longtime, well-regarded Avenger and a fan favorite.
The ‘Prince of Power’ is kind of like Avengers: Endgame‘s ‘Bro Thor’ without the self-doubt, and even though Odinson seemed to get his mojo back at the end of the film, the MCU has room for another hard-partying, powerhouse hero that revels in being a powerhouse hero, particularly with the God of Thunder seemingly preferring outer space to Earth these days.
While not initially revealed as a cast member, Hercules has been rumored to be part of Eternals, which makes some sense given their ties to ancient Greek and Roman mythology. Hercules may just make for a perfect bridge between Marvel Studios’ newest franchise and the Avengers when the Earth’s Mightiest Heroes return in their next incarnation.
