|This article is about a/an group of villains in Hyakujuu Sentai Gaoranger.|
Zeus Org (ゼウスオルグ, Zeusu Orugu) is the oldest brother with power over thunder. He wielded a sword shaped like a thunderbolt and his special attack was called Devil's Thunder. He was the leader of the Orgs on an island in another dimension and forced the natives to mine for a special ruby that contained GaoKong's power. Zeus was successful in slaying Kaito who was attempting to protect the Princess and then fought GaoSilver, who fended him off until the rest of the Gaorangers arrived and defeated him, causing his flaming body to fall into the ocean below. Zeus resurrected as a giant and revived his brothers just in time for the eclipse to summon GaoKong occurred. Destroyed by GaoKnight.

Poseidon Org (ポセイドンオルグ, Poseidon Orugu) is the middle brother with power over water. He wielded a trident. When the Orgettes kidnapped Tetomu, Poseidon wanted her as a companion and invited her to a drinking game at dinner with his brothers. Having won the contest, Tetomu was awarded half of the ruby by Poseidon. When GaoRed and Kaito attempted to rescue Tetomu, Poseidon attempted to fend them off and despite being drunk, was an effective fighter. It wasn't until GaoYellow joined them that he was bested. He later joined his brothers in fighting the Gaorangers and the islanders and was destroyed, along with his brother Hades, by the Gaorangers before being resurrected as a giant by Zeus. He was the first to attempt to attack GaoKnight but was destroyed by a quick stroke by GaoKnight's sword.

- Poseidon Org's motif is based on the anglerfish.
- Originally in "Reinforcements from the Future," it was supposed to use these Three Org Brothers Zeus Org, Poseidon Org, and Hades Org from Hyakujuu Sentai Gaoranger: The Fire Mountain Roars as the Mut-Orgs. However, they could not be afforded after all these costumes were reported to have been lost in a fire resulting in the creation of the Mut-Orgs.
- Three Org Brothers were designed by character designer Yoshiro Harada.
