Don Kee is the extremely money-hungry, pretty boy overlord of Planet Imecka and the first villain in Dragon Ball GT.
When Don Kee took power on Imecka, he made it illegal for anyone to own spaceships so that no one could leave the planet. To enforce his will, he relied on his bodyguard, Ledgic, and his two commissioners, Sheila and Gale.
When Goku, Pan, and Trunks arrived on the planet, Don Kee quickly had his underlings confiscate the space ship they arrived in. After the trio was successful in retrieving it, he declared them wanted criminals and sent his minions out to track them down. After Goku, Pan, and Trunks attacked Don Kee's palace, he ordered Ledgic to fight him. However after Ledgic left him, Goku, Pan, and Trunks taught Don Kee a lesson and made him give back everything he took from the Imeckians.
He was later seen with Sheila and Gabe in a prison, giving his energy to Goku for his Universal Spirit Bomb so he could destroy Omega Shenron, though he did this reluctantly.
