Burnsy'd give it his best, but...

he's capable of crippling a child but that's about it. can't even steal candy from a baby without murdering himself

Mustache guy is Snidely Whiplash from Rocky & Bullwinkle.

Edit: Nope, the other one was right, Dick Dastardly.

I'd replace Dick Dastardly with Boris Badunov and Natasha Nogoodnik, as they would be sent to make sure Russia's interests are covered.

Swap out Vader for Jabba the Hutt; one violent, disgusting, sexually depraved slug belongs with another.

Burns and Cruella are both just about vile enough to fit into this picture.

Trade Hannibal for Buffalo Bill. He's about at Trump's level. Maybe director of Health and Human Services.

I'd trade Joker for Hugo Strange, because despite being an evil psychiatrist, his defining trait seems to be having a poor understanding of the even more psychotic people around him, so he'd be the ostensibly intelligent person in the room who thinks they can manage Trump and get him to do the specifically horrible things they want him to do, and instead he's just going to shit in their Cheerios and make them eat it on live television.

At this point I imagine he has received enough inaugural awards to memorize the word.

Cruella de Vil, Dick Dastardly

Cruella DeVille, 101 Dalmations; Dick Dastardly, Wacky Races.
