It begins and ends with one man.

Dr. Doom.

The character...the history...the narrative...has Oscar/Emmy Gold written al over it should it be done by the right people whether in a series or as a set or films.

My dream casting for the MCU is Margot Robbie as Emma Frost.

Malakeith - never
Gobby - absolutely
Lex Luthor - Snyder couldlnt' have screwed that up any worse. Making Superman's nemesis a doofus throwaway character is among the high crimes he has committed against American Popular Culture
Ultron - yea, I don't think so but it's more of a possibility than a lot of the others.
Scarecrow - Cillian Murphy did a fine job. Are there no other villains that can fight Batman? Does some other studio own the rights to Condiment King?
Bullseye - again this is played out and if DD does come back he will not be on his own for at least a decade.
Doom - This is among the most criminally underserved characters in the rape of Marvel properties by others. He will be showing up and that right soon.
Bane - Again, can we get another of Batman's nemeses already? Jeep Swenson was far and away the definitive Bane.
Emma Frost will be waiting a decade or more. X-Men are a long way off.
Galactus - This takes the cake and all major awards for screwing up an epic character to epic proportions. Tim Story and those hack writers who thought it would be a good idea to make Galactus an amorphous space cloud will live in infamy. We will see him soon in all his purple helmeted glory.

Can we get an actual Hispanic for Bane next appearance?

Bullseye was already great and should be brought back. Malekith under Waititi would be cool.

We've seen Goblin enough times already. Do Hobgoblin and the Dark avengers before then.

Wait, is Bane iconic?!😂 Because of Knightfall? I disrespectfully disagree with that!😂 I'd like to see the character again. But only as a side villain. His character motivation is usually pretty weak in the comics, even if you don't include Tom King's run.😂 That's likely why Nolan attached him to The League of Shadows (Assassins). Making him more of mercenary/terrorist, than just a dude that wants to out muscle Batman.

I think with the characters being in Marvel Studios' hands now, I think it's a given we'll get Galactus and Doom one day. It might be another 10 years, but they'll be there.

Lex Luther definitely deserves a second chance though. I didn't mind Eisenberg's performance, but he wasn't Lex. Just recon him into Lex jr. and bring in the real Lex.

I'm sure they said the same about Hook and Cruella.

Yeah, after the Green Goblin we got in Amazing Spider-Man I'm looking forward to one that actually comes off menacing instead of goofy.
