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 the Venture family: well-meaning but incompetent teenagers Hank and Dean Venture; their emotionally insecure, ethically challenged super-scientist father Dr. Thaddeus "Rusty" Venture; the family's bodyguard, originally the ultra-violent and macho secret agent Brock Samson and his later replacement, reformed super villain and "cured" pedophile Sergeant Hatred; and the family's self-proclaimed arch-nemesis, the Monarch, a butterfly-themed super villain.
