Korath
Korath, a member of the Kree species, appeared in 2014’s brilliant Guardians of the Galaxy movie. He worked under Ronan - who, in turn, worked under Thanos - and was a relatively minor supporting character as a result.
There really wasn’t anything wrong with this version of the character, but the problem was that the less-than-prominent role he had in the story meant that the brilliantly talented Djimon Hounsou was totally wasted in the role.
Hounsou is a two-time Academy Award-nominated actor and he was reduced to a bit part. Once he was cast as Korath, the character should have been given a much more prominent role in the movie. Instead, he had only a few lines and was killed by Dave Bautista’s Drax.
And now we move on to one of the aforementioned villains under whom Korath was working.
