Jibaku-kun

Jibaku-kun (ジバクくん) is a Japanese manga series written and illustrated by Ami Shibata. It was adapted into a 26-episode anime television series called Jibaku-kun: Twelve Worlds Story (ジバクくん TWELVE WORLDS STORY) which was broadcast on TV Tokyo from October 5, 1999 to March 28, 2000. In some markets, the series is known as Bucky: The Incredible Kid, Bucky: Searching for World 0 or simply Bucky.

Story
The story is set in a place called Parallel Planet, located above the sky and down the sea. This planet is divided into twelve worlds, in the manner of a clock. In the center of this clock is the Needle Tower, World Zero, where time does not pass. In each world there is a Great Child, something like the guardian of that world. The Great Child is always accompanied by a spirit, an explosive, spherical side-kick that helps defeat the Troublemonsters.

Baku (Bucky in some versions) was a normal boy with one ambitious goal in mind: to take over the world and make everyone his slaves. When En (Spaak), the Great Child – someone specialized in fighting against troublesome monsters – of World One, entrusts him with his Spirit and G.C. Watch, Baku embarks on an adventure through the twelve worlds to make his dream a reality at all costs.
