not related to the Ventures per se, Brock is the bodyguard of the Venture family and an agent with the Office of Secret Intelligence. As a "Super Secret Agent," he has a license to kill and an amazing zeal to use it. His background has been revealed to be "half Swedish, quarter Polish, quarter Winnebaego". Though Brock usually displays a relaxed and casual attitude, his temper can cause him to snap into psychotic violence at the slightest provocation. His ability to dispense punishment is equaled by his ability to sustain it, to the point that he is seemingly unkillable. He also has a superhuman sexual appetite, with conquests ranging from beauty queens to sleazy strippers to "the Queen of the Ant People." He is extremely loyal to the Venture family, actually living with them in the compound, and now seems to serve as a bit of a mentor for the boys, with whom he shares an avuncular relationship.
