In Spider Man: Across the Spider Verse appeared a Prowler in Live-Action form from an other universe, and this universe was the MCU because the same actor who did Aaron Davis in Spider Man: Homecomming, Donald Glover did him in Across the Spider Verse. So why those informations don't exist in the page (there are some in the "Behind the Scenes" , but I think that it must t be an entire chapter)? He is from a non-MCU movie but he is in the MCU universe.
