Best as in respectable, honorable, epic, etc.

Killmonger comes to mind.

"Hell of a move."

"Bury me in the ocean, with my ancestors that jumped from the ships, because they knew death was better than bondage."

@gateofbabylon: That was such a good line

Killmonger

Killmonger and Thanos

Thanos.

Killmonger followed by Thanos

Killmonger, Loki (in both Thor 1 and Avengers), Thanos, and Hive.

Loki in Avengers.

Thanos for me (no surprise lol).

Ultron’s talk with vision at the end of AOU was good imo.

Vulture was pretty good keeping Peters secret.

Loki was done well.

@finalkingthanos: Yeah I'm surprised no one else mentioned Ultron.

Thanos

"Enough you dull creature! I'm a god and I will not be bullied by..." smash smash smash smash smash

"So how does it feel? To spend all that time, all that effort, and to see it fail so spectacularly?" "Did it?"

Thanos and Hela were good, too.

"I am inevitable"

Kurse because he hug stabbed Loki

Ultron by far

Thanos before he got his head cut off by Thor and Killmonger.

Yea Killmonger.

Killmonger.

Thanos.

I mean everyone is saying Killmonger/Thanos so I guess my favorite villain Crossbones and Arnim Zola since Crossbones started the Civil War and Zola almost got Steve and Nat killed.

Thanos or Erik

Ultron

Thanos
