%%* OneWingedAngel: In the finale as a result of his consuming the Heart of Godom, calling himself Gajadom.

A group of Japanese-based thieves who are out to make big bucks by stealing Preciouses. Consist of Maboroshi no Gekkou (owl), Kaze no Shizuka and Yami no Yaiba.

* AntiVillain: They're called Dark Shadow, they're antagonists, but they're the least ''evil'' amongst the Negative Syndicate since Gekkou and Shizuka are not interested in causing harm to humanity unlike Gaja, Ryuuon or the Questers, they just want to make a lot of money and can be shown to be friendly to the Boukengers. Except for [[TokenEvilTeammate Yaiba]].

* ArchEnemy: Yaiba is this Masumi.
* The Dragon
* DragonInChief
* KnightOfCerebus: Yaiba, the first completely serious villain we get in the series.

They're Eiji's ArchEnemy.

%%* BackFromTheDead:
%%* BoisterousBruiser: Gai is a villainous example, combining efficiency, bravado and {{Troll}} laugh whenever things go his way.
* EvilCounterpart: They were made into Questers by Gajah using research on the Boukenger's Parallel Engines. Their Quester forms and SwissArmyWeapon also look vaguely Rangerlike. And to top it off, they also use HumongousMecha during each of their appearance, instead of going for human sized monsters that grow bigger upon defeat.
* EvilIsNotAToy: Gaja revives them with the Godom Engines, but didn't actually come up with a plan to control them.
* {{Homage}}: To nearly all the mecha of ''Series/GoseiSentaiDairanger''. Gai is Ryuuseioh, Rei is Won Tiger, Quester Gai is Dairenoh, Quester Rei is Kiba Daioh, and Hyoga is Daimugen.
* HumongousMecha: The Quester Robos, most of which were designed specifically to use a particular Precious.
* KnightOfCerebus: Are treated as the biggest threat in the show and tend to be the toughest to fight [[spoiler: ironically are the first to die.]]
* NotQuiteDead: Their apparent status between being killed as Ashu and revived as Questers.
* OffscreenVillainDarkMatter: Where ''do'' they keep getting those mecha?
* SealedEvilInACan: Rei was trapped in a mirror, along with the rest of the Eastern Ashu, until Gai and Hyouga found a way to bring Rei back.
