Gelbo

Gelbo (ケルボ, Kerubo) is a planet with intense seismic activity. It is also where the Six-Star Black Star Dragon Ball landed on.

Overview
Gelbo is populated by the Gelboians and a catfish monster called Zoonama. Trunks disguised himself as the princess of this planet, Leena, and was taken to Zoonama's lair, where he, Leena's fiancé, Doma, Goku, and Pan defeated the monster.

Gelbo is later seen when the Gelboians give energy for Goku's Universal Spirit Bomb used to defeat Omega Shenron.
