|1st appearance:||Tag-Sale -- You're It!|
Mister 5 was one of the rookie Secret Service agents assigned to the infamous Venture Compound Tag Sale. He was charged by Mister 1 to kill Mister 11 before he reached the front gate after he decided to quit. He without question eliminated Mister 11. His character model was also seen at one point working with Professor Impossible to capture Ned, Hank and Dean, although this is mainly because the design of The Venture Bros. was underfunded at the time.
