Dark Shadow (ダークシャドウ Dāku Shadō) is a stealth assassin-group descended from the ninja order called the "Society of Shadow" (シャドウの結社 Shadō no Kessha). They are experts in espionage that work to obtain the Precious for the highest bidder. Dark Shadow has no footsoldiers of its own, but Yaiba and Shizuka do utilize the Karths on several occasions. After Yaiba's betrayal and Gajah's final attack, Dark Shadow halted its actions and left the country.
Several years later, after the Great Legend War, Gekkou and Shizuka were among the former villains imprisoned by Zangyack in the Makuu Prison. They were released by the Gokaigers when they broke into the prison to save Gavan.
