Ana was a 2020 repeat who slipped in because I grabbed the wrong character (fortunately I have plenty of time to put in the intended character elsewhere).  In the case of the Wolverine from Deadpool 2 it's worth noting that he's the one from Earth-18315 and not the main Deadpool 2 Earth, which is Earth-41633; still he's the only Wolverine in the movie so the answer counts. I tried to avoid Mystique impersonations but I guess with over 3K characters these sorts of errors are bound to slip in. Beyond that, everyone is correct; list updated.

Whenever Maher goes on about how unhealthy Marvel movies are, I can't help but wonder if on some level he's upset that his lengthy scene in IM3 got cut. Ordinarily I wouldn't include an unnamed jury foreman from a dream sequence, but because it's Stan Lee, he made the cut.

Just a reminder to be more specific than MCU because over half the characters in this collage are from the main MCU Earth (doesn't have to be first appearance). I might allow it anyway but I definitely won't if it's a common name
