The Venture Bros Season 3 Episode 10 - The Lepidopterists Episode Title:The Lepidopterists.Episode Description:Jonas Jr. seeks advice from Brock and two OSI agents, Mr. Doe and Mr. Cardholder, on how to deal with his new nemesis, The Monarch. They authorize him to eliminate the villain using a death ray, since The Monarch has killed his last five archenemies. The Monarch sends Henchmen 21, 24, and 1 to infiltrate Spider-Skull Island, but Henchman 1—true to 21 and 24's prediction—is beaten and seemingly killed by Brock. Their mission is a success, however: Jonas Jr. is fooled into thinking that he has eliminated his enemy, and his use of lethal force opens a loophole in the Guild of Calamitous Intent's rules that allows The Monarch to resume arching Dr. Venture.
