Who would you like to see? For example, I would love to see Count Nefaria, one time as a simple mastermind and another time in his full powered state, where he was shrugging off all of the Avengers at the same time including Thor and it took a maximum density Vision hitting him at terminal velocity when he wasn't expecting it just to knock him out. I seriously doubt I'll see this. But I'm sharing this as I love the Count. Graviton was another, but he just popped up in AoS pre-powers, so who knows? Korvac is my third.
