Yatterman

Four magical skull pieces are scattered somewhere, and whoever gathers them all will be able to control the world. Gan Takada (Sho Sakurai) and his girlfriend Ai-Chan (Saki Fukuda) run a toy shop, then become the heroes Yatterman 1 and 2 whenever trouble starts, with a dog-shaped robot called Yatterwoof at their side. Takashi Miike sets them against the Doronbow gang and its leader Doronjo (Kyoko Fukada), who want the skulls first.
