Bring back Hela!!

I want Loki back. If he doesn’t count as a villain, Hela would be a great one to return, and being the goddess of death, it would be possible.

Ultron

Evil Phil Coulson.

If Ultron were to make a return, I imagine it would be in a Phalanx invasion storyline.

It would go something along the lines of: Ultron beamed his consciousness out into space in a last ditch attempt to save it before Vision closed his network off from the rest of the world’s network.

That beam of data signals found its way to the technorganic Phalanx, whom he infected and reassembled into an Ultron army.

And he begins heading back to Earth in a vendetta against the Avengers.

evil Phil Coulson; his Framework version?

Actually I meant Sarge, from the last season.

Sarge kind of turned into a good guy in the last episodes.

edit: Sarge and Coulson I count as 2 different characters.

Actually he tried to kill the Shield team in the last episode and that he was never a good guy in the first place, look it up.

Ronan, Malekith, and Dormammu
