Planet Imegga (惑星 イメッガ, Wakusei Imegga; FUNimation "Planet Imecka") is a planet in the Northern Galaxy.
Dragon Ball GT
Planet Imegga was ruled by Don Kee. It has two moons. It was the first planet that Son Goku, Son Pan, and Trunks Briefs landed on during their journey to collect the Black Star Dragon Balls in Dragon Ball GT. Planet Imegga had a desert climate and was home to the Imeggans. Under the rule of Don Kee, the Imeggans were incredibly poor due to the high taxes used to furnish Don Kee's lavish home. Many of the planet's inhabitants were homeless and marketplace sellers tended to be swindlers. Goku, Pan, and Trunks met Gill on this planet.
