Yatterman

Every week, toy-shop owner Gan and his cute assistant Ai battled the evil Doronbo gang. The gang led by femme fatale Doronjo and her assistants-pig-nosed muscleman Tonzra and rat-faced mecha genius Boyacky-for pieces of the mystical skull stone, and every week the Doronbo gang failed (usually due to incompetence). Then there was a mushroom cloud, Gan and Ai did their Yatterman dance and the gang regrouped the following week to do it all over again.
