The Venture Bros. is an American animated television series that premiered on Cartoon Network's Adult Swim on February 16, 2003. The series mixes action and comedy together while it chronicles the adventures of two dopey yet well-meaning teenage boys, Hank and Dean Venture; their emotionally insecure, ethically challenged super-scientist father Dr. Thaddeus "Rusty" Venture; the family's bodyguards: ultra-violent and macho secret agent Brock Samson and later the former super villain and "cured" pedophile Sergeant Hatred; and the family's arch-nemesis, the Monarch.
