So, it is unclear what kind of Marvel gear Rey Mysterio is planning for WWE’s WrestleMania 41. He has previously worn outfits inspired by Captain America, Spider-Man, and Daredevil.

Previous references and Easter eggs hinted at the MCU being Earth-616, including a mention by Mysterio ... In the Marvel Universe - encompassing all Marvel media, including movies, comics, video ...

But is he friend or foe? The trailers have not been clear on that part, so there is a remote possibility that this version of Mysterio might be a hero ... but his comic roots state otherwise.
