Darrell

Darrell is a robot created by Lord Boxman. Darrell plays the role of Lord Boxman's loyal henchmen. Like his siblings, he has a hive mind, which means all Darrells share one mind. He first appeared in the pilot as the main antagonist and is a recurring antagonist in ''OK K.O.! Let's Be Heroes'', in which he was first briefly seen in "Let's Be Heroes."

At the end of the Season 1 finale "You're in Control", he reveals to Lord Boxman that he called the villain's board of investors about the destruction caused by Boxman Jr., leading him to get fired both from his job, and launched from a cannon of Darrells into the sun. Cosma then reveals that Darrell has been chosen to be the new head of Boxmore.

Darrell is also a boss in ''OK K.O.! Lakewood Plaza Turbo and an enemy in OK K.O.! Let's Play Heroes.''
