Warning: Contains SPOILERS for Conan the Barbarian: Battle of the Black Stone #4! Conan the Barbarian is already widely regarded as a classic Marvel Comics character, having been featured in his own solo Marvel book since the ‘70s, and even teaming up with Marvel’s other most hardcore heroes in Savage Avengers.

That means Conan exists both within and outside of the Marvel Universe, but now, he wants back in – and this time, Conan has his sights set on the MCU.
