Bommon

Bommon is a Slime Digimon. It has a bomb-shaped body. The fuse on its tail ignites the moment it hatches from its egg and steadily grows shorter, but because it digivolves to the next generation before the fuse disappears, nobody knows what will happen if the fuse goes out. It possesses a short-tempered personality, and it's said that when it gets in a bad mood, the progress of the fuse gets faster.

Attacks
 * Bachibachibacchin (バチバチバッチン): Suddenly produces intense crackles from the sparks of its fuse, surprising any opponent who sees it.
