The Enforcer Sergeant was an able-bodied and loyal Enforcer officer, never identified by name. He is usually seen at Commander Feral's side. The Sergeant is completely loyal to Feral and always follows his orders without question. A kat of few words, the stern Sergeant normally says nothing more than, "Yes sir!" in response to Feral's commands. The Sergeant's first chronological appearance was when he assisted Feral in trying to solve the mystery of the missing body of Dr. Elrod Purvis (it was later revealed that Purvis had been revived as the mutant Dr. Viper). Later he tried to arrest the Pastmaster as he came out of the Megakat City Museum of History with the Tome of Time, and was almost stepped on by a Megasaurus Rex for his troubles.
He was at Feral's side during the siege of the Megakat Tower, and when Dark Kat and the Metallikats teamed up with Dr. Viper, he played chicken with the Metallikat Express in his tank and lost. He bailed out as the Metallikats' armored hovercraft slammed into the tank and knocked it over. When Feral was captured by Madkat and Lieutenant Commander Steel took over as Commander of the Enforcers, the Sergeant grudgingly followed Steel's orders by often openly criticized his poor leadership skills. During Mutilor's attempt to steal all of Megakat City's water, the Sergeant was dispatched to personally look for the missing Felina Feral, but although he only found her crashed jet and bazooka.
