King K. Rool is a hot-tempered, authoritarian and baleful green Kremling who was the main antagonist of many "Donkey Kong" games and has been Donkey Kong and Diddy Kong's archenemy ever since his creation during the era of Rare development. The despotic king of Kremlings and master of Kremling Krew, he constantly antagonizes the Kongs, referring to them as "filthy apes," "monkey brains," and "ludicrous lemurs" as well as frequently robbing Donkey Kong's Banana Hoard. His most distinguishing features are the tic in his left eye, his red cape, his gold crown and wrist bands, and his yellow belly (originally the golden front armor) with an outie navel, his tail seems to change size or disappear completely between appearances. While overweight, K. Rool has huge muscles in his arms and he has proven to have enormous brute strength that matches (perhaps surpasses) both Donkey Kong and Chunky Kong in power. Additionally, according to the Japanese localization, K. Lumsy is his younger brother.
