King K. Rool

A fat Kremling who acts as Donkey Kong's Arch-Enemy in the Donkey Kong Country series. Prone to adopting new personas (Kaptain K. Rool, Baron K. Roolenstein, etc.) in different games, complete with new powersets for battle. Whatever he likes to call himself, K. Rool's goals remain the same — to get rid of the Kong clan and take over their island, and if he can't manage that, destroying the island along with every primate on it suits him just fine instead.
