“Ahhh... those were the days. Beating up bad guys and blasting narrators.” —The Chief, Internal Affairs
The Chief is a tough but good-natured flea who runs T.U.F.F. headquarters. In "Internal Affairs", it's revealed that his real name is Herbert Dumbrowski, he has a bionic foot, has short term memory loss, and is extremely strong for somebody so small. The Chief was once T.U.F.F.'s top agent and an amazing fighter. In one episode, he comes out of retirement to help Dudley deal with the Chameleon. While things don't work out well at first, Dudley manages to give him a pep talk and he shows he's still got it by beating up the Chameleon.
The Chief may be smaller than a penny, but he packs the punch of an angry bull. A grumbly, no-nonsense, battle-scarred flea, this tough-talker has seen and done it all. To make sure he gets his points across to his crime-fighting friends, The Chief uses a video camera rigged up to a floating big screen TV to always appear larger than life and it works. When The Chief speaks, EVERYBODY listens. Thanks to him, T.U.F.F. is a well-oiled machine and D.O.O.M. agents are too busy running for their lives to make too much trouble. The only loose end he can't seem to tie up is his reckless new recruit, Dudley Puppy. The Chief would love to keep a closer eye on him, but Dudley's flea collar makes that harder than you'd think.
The Chief is known to act like a chief. He is always commanding the gang to orders of which they are capable or known of.
The Chief hires T.U.F.F. agents on the spot quite easily, as he did with Dudley and Snaptrap, despite the circumstances of their past battles. Even though he is blunt, abrasive, grumpy, and forgetful at times, the T.U.F.F. agents still look up to him, or down, depending on if he is using a video monitor to broadcast orders or not. The Chief is a little past his prime and has false teeth, a toupee, and a bionic foot. Despite these traits, he is shown to have a strong will and a take-charge attitude.
Interactions with Other Characters (Alphabetically)
In Internal Affairs, The Chief was Dudley's partner after Dudley got shrunk by Keswick's shrinking ray. The Chief sometimes gets a little irritated by Dudley and the crazy things he does, as seen in Mission: Really Big Mission, shutting him up with the Fist-in-a-Box, after he lost his Space Jerky.
The Chief has a small rivalry with The Chameleon, though in Internal Affairs he easily beats up The Chameleon. In Lucky Duck, The Chief shows little interest in The Chameleon's plan to blow up Pluto due to his interest of the show, Quacky the Duck.
