He surprised fans at the San Diego Comic-Con Special Edition by walking on stage, in full costume, during the Peacemaker portion of the cosplay contest.

Cena shared a video of the entire sequence of events on his Twitter account, with him showing up on stage wearing his traditional red, blue, andbeige Peacemaker costume.

The video begins with Cena arriving at an airport and waving at an empty airfield, a great representation of Peacemaker’s true character. He believes he is extremely popular, as was visible in anewPeacemakerclipaired during San Diego Comic-Con Special Edition. When arguing with the hospital janitor, he insists on his popularity and curses at Aquaman because the janitor seems to think that the hero is more popular than Cena’s character.

During his appearance at San Diego Comic-Con Special Edition, Cena even teased a potential second season of thePeacemakerseries. “Peacemaker on HBO Max on January 13. Please don’t miss it, because I really like doing this stuff, and I’d like to do it again,” he is heard saying.Director James Gunnhas previously also said that he would like to continue makingPeacemakercontent, so there is a possibility that this isn’t the last that fans will see of Cena’s character.

The actor was also seen surprising some fans who were participating in a paintball contest. He even posed for pictures with cosplayers and was caught on camera hugging an individual dressed as Eagly. “I won’t forget this,” he says excitedly.

Gunn’sThe Suicide Squadpremiered in theatres in August of this year, and Peacemaker was a part of Task Force X, a black-ops unit that was founded by Viola Davis’ Amanda Waller. He is later revealed to be a mole for the government and plans to destroy all the evidence on Starro, the giant starfish that is being hidden at Jotunheim in Corto Maltese. After his true motive is revealed, he goes up against Idris’ Elba’s Bloodsport and is left for dead. However, in the post-credits scene of the film, it is revealed that he is in fact alive, which sets up thePeacemakerseries perfectly.

Peacemakerpremieres on HBO Max on July 16, 2025.
