He's more or less in permanent debt to Dr. Venture, and spends a majority of his time keeping his genetic offspring from being killed. Too many times.
Plus the voice actor for Brock is awesome.
Can't remember his name atm
He
doesn't always keep them from being killed! So many clones!
But it's almost a running gag w/ him and Dr. Venture, so...you know. Whatever.
Patrick Warburton is his name. He's also Joe on Family Guy, Rip Riley in Archer, and about a billion other things. He was The Tick on the live action version of the show, and he was David Puddy on Seinfeld which still might be one of his more "memorable" live acting roles.
