Lord Boxman

Lord Boxman is the main antagonist in the Season 1 of ''OK K.O.! Let's Be Heroes'' series, appearing in both the animated series and games. He made his first appearance in the pilot "Lakewood Plaza Turbo". He is the creator and former boss of the factory Boxmore, which sells robot minions and supplies to all the villains of the world.

In the season finale "You're in Control", he was fired by the villains board after Darrell tells them that his new creation, Boxman Jr., destroyed the Boxmore building. He was then put into a cannon made of Darrells, and shot into the sun, then replaced by Darrell as the head of Boxmore. He returns, however, in "Lord Cowboy Darrell".
