An evil sorcerer who was trapped for 800 years, now released he seeks control over Megakat City in order to turn it back to the Dark Ages.
A very short sorcerer from the Dark Ages who tried to conquer his home city. He travels through time using his magical mechanical pocket watch, and with his magical book The Tome of Time, he’s able to bring back extinct or mythical creatures (such as dinosaurs and dragons). Although the tome was destroyed in his first appearance. Seeks to transport Megakat City back to the Middle Ages. He was supposedly killed in The Deadly Pyramid.
He first appeared in The Pastmaster Always Rings Twice. In A Bright and Shiny Future the SWAT Kats were drawn into a future where the Metallikats together with the Pastmaster had created a Terminator-inspired future where machines ruled over katkind and The Swat Kats are aware of what lies for them in the future. All the Pastmaster really wants is to go back home to his own time. He is occasionally shown to lust after Callie Briggs (the spit image of her ancestor Queen Callista, the Pastmaster’s ancient crush). He repeatedly captures her and ‘asks’ her to marry him, but Callie will have none of it.
