Biobase

Biobase is the base headquarters of Bioman. Located in a cave around Mt. Fuji, it was established by Peebo after he and Bio Robo arrive on the planet following Bio's destruction five-hundred years in the past. Hidden by a cave complex, it has modern technology and a launchpad for vehicles like BioDragon and Bio Robo itself.

Not too long after Peebo's arrival on the planet, a local created a map that included BioDragon at the end of the path, unintentionally discovering Biobase and leading to two children to follow it and ultimately meet Bioman in the present day.
