The Chief

The Chief (voiced by Daran Norris) - A tough and strict but good-natured flea who runs T.U.F.F. headquarters. Subsequently, he's Dudley's employer and (although he's usually getting angry at Dudley and yelling at him) he seems to be somewhat proud of him as an agent. In "Internal Affairs," it's revealed that his real name is Herbert Dumbrowski and he used to be T.U.F.F.'s top field agent until he retired and became (or was most-likely awarded) the chief of T.U.F.F. The episode also revealed that he has a bionic foot, has short term memory loss, and uses a toupée (all due to his aging).
