Well then, all silliness aside, let's start this thing off.
In DK lore, there have been three true villains - namely King K. Rool (under different aliases), Ghastly King, and Tiki Tong.
K. Rool was just some asshole who decided to troll DK by stealing the banana hoard, Ghastly King was an evil monkey from SPACE that wanted to rule over the Fruit Kingdoms for no real reason and Tiki Tong stole the banana hoard to keep his race alive and possibly take over the world. Fair share of hindrances, right? It is nothing compared to the vast amount of baddies Mario fought in the past, but this is mostly to blame on the fact that Nintendo obviously favours Mario over Donkey Kong. Which is saddening, because they debuted in the same game.
Anyway, K. Rool and co. were typical antagonists, setting up the games' plot. But what about those other characters who had done unspeakable things people presumably forgot all about because they weren't the main villains?

3. Bluster Kong
Bluster Kong is one of the show-only characters, and nearly everybody who doesn't appreciate the show blames their dislike of it on Bluster. I honestly don't blame them - while this specific Kong provides a lot of humorous scenes and dialogue and I don't mind him, he takes up a lot of space, having three episodes with him in the limelight.
He's a pathetic mommy's boy, constantly whining about his mother and whenever he has to do manual labor, all hell breaks loose. Figuratively, of course. Bluster can't really... do anything. He's not strong, he can't jump high, and he certainly isn't a hell of a guy. He also has a grudge towards Donkey Kong, for the sole reason that DK is constantly hitting on Candy, the only adult female ape in the cartoon who isn't Bluster's mom or Great Aunt Grouchy. Bluster is not happy with this because he too has an eye on Candy, to the point where he gets a bit desperate in some episodes, like in A Thin Line Between Love and Ape, where he makes a love potion to make her love him.
Evil?
The episode Bad Hair Day, AKA the only episode most people know of, had him being introduced as another all-around jerk. Fair enough. But eventually, Donkey Kong loses his hair (and his muscles) and Cranky makes a potion to make it grow back. Candy and Bluster set out to find DK. Eventually, in the jungle, Bluster complains that "I can't walk anymore! My feet are sore, I've got sand in my shoes, and I'm thirsty!" leading to him snatching the potion from Candy. He empties the bottle on the ground.
