Dark Kat is the main villain in Swat Kats. Some say he used to be a judge in order to get criminals on the streets instead of prison. He is a smart and dangerous crime lord. His appearance is similar to a demon. He was voiced by the late Brock Peters.
Dark Kat may have been a tactician or a scientist, but one day he found something that warped his mind and body, and gave him control over the gargoyle-like creatures called Creeplings.
- Due his brilliant mind and the scientific skill he exhibits, he may have been based on Doctor Doom, archnemesis of the Fantastic Four.
- His Creeplings and his own origin are unknown. It's not clear if he's a demon or a mutated scientist, and the same goes for his Creeplings. They may either be Dark Kat's creations or lesser demons.
- In the episode Razor's Edge, Dark Kat didn't use the Creeplings to invade the Megakat Semiconductor; instead he employs ninja-dressed inflitrators.
