K. Rool, as his name, a pun on "cruel," may imply, is brutal, ruling his minions through threats and intimidation, often punishing them severely when they fail. This is mentioned by Klubba in Donkey Kong Country 2: Diddy's Kong Quest, who says that K. Rool mistreats his minions. This is also seen in Donkey Kong 64, when he presumably executes a purple-haired Kasplat via a giant Klaptrap for calling him "fatso", not realizing that K. Rool was listening. Even his most powerful followers seem to fear his wrath, as displayed in Donkey Kong 64, when his subtle display of anger results in Army Dillo fainting on the spot, and Dogadon ends up begging for mercy over his failure when admitting how his wings ended up singed by the Kongs (although K. Rool seems more shocked than angry at the failure regarding the latter). He does not seem to respect his henchmen, the Kritters, much better either.
