I deliberately didn't put their names anywhere so you can test yourself.
We often say the Marvel villains are forgettable, but it was only the other night when I was talking about Marvel movies with my housemates and we couldn't remember who the hell the villain even was of one of the movies that we realized how true it is.
(And of course I didn't draw every single villain because that would be a lot)
Loki, Stane, Abomination (Blanksy?), Red Skull (Johan Scmit?), that AIM/Extrimis Jerk, that Elf Jerk, Pierce Jerksomething, Ronan, Ultron, that Yellow Jacket Jerk.
Loki and the Jerks.
