Avengers Confirms the WWE's Greatest Wrestler Exists in the Marvel Universe At the end of Avengers #25, Tony Stark/Iron Man found himself thrown back in time a million years after finding a fossilized version of one of his own helmets. The book has mostly left Tony's fate ambiguous since then, choosing instead to focus on the battle between Earth's Mightiest Heroes and their powerful cosmic foes. However, Avengers #31 brings the action back to Tony, and reveals WWE champion Brock Lesnar exists in the Marvel Universe. The issue opens with Tony facing down a vicious wolf, which he blasts the head off of using his repulsors. Tony thinks back on a fight against the 1,000,000 BC Avengers a few weeks previous. Created by Jason Aaron and Esad Ribic, that group first appeared in 2017's Marvel Legacy #1 and consists of Starbrand, Phoenix, Odin, Lady Phoenix, Agamotto, Ghost Rider and the first iterations of both Iron Fist and Black Panther. While fighting the group, Iron Man says, "Look, Ghost Rider Snuffaluffagus and Brock Lesnar Starbrand are one thing, but no way am I getting slapped around by Thor's daddy!" He's then gets blasted from the battle by Lady Phoenix. The reference to Lesnar here indicates someone as hulking as the wrestler does exist in the Marvel Universe, though it's not super clear what form that might be in. . The context of the comment makes clear the Marvel Universe's Brock Lesnar is a fighter and not just a world famous super jacked insurance salesman. However, Tony doesn't mention the WWE, so it's possible this alternate version of Lesnar works for some other promotion. As evidenced by Spider-Man's origin story, professional wrestling does exist in the Marvel Universe, so it's entirely possible the WWE does exist, even if it's not being named explicitly.
