Bolon was among the Dark Vassals spawned by King Piccolo who survived the King Piccolo wars.
In Age 853 Piccolo became aware of the other surviving spawn of King Piccolo, discovering some had secretly incubated in places like Pilaf's Castle and others had bred naturally in the wild. Piccolo and a few other Namekians captured these spawn, and they were studied by the Dragon Clan, who worked out how to spawn and handle creatures identical to them.
