Kiba Changer (キバチェンジャー,Kiba Chenjā, Fang Changer): Kou's own transformation device. It has a golden key, called Kiba Emblem (キバエンブレム,Kiba Enburemu), that is inserted into a brace similar to the Aura Changer's left piece, the Kiba Spreader (キバスプレッダー,Kiba Supureddā). The transformation call is "Chi-Power Tenshin, Kiba Changer!" (気力転身, キバチェンジャー!,Kiryoku Tenshin Kiba Chenjā). In the later episodes, sequence appears almost similar to Dairanger's one, but with the Kibaranger symbol spinning rather than Dairangers' one.
At the climax of the Legend War, the Kiba Changer was made redundant when KibaRanger sacrificed his powers with the rest of the first 34 Super Sentai to destroy the invasion force of the Space Empire Zangyack. Resurfacing a Ranger Key, the power of KibaRanger would be used by the Gokaigers to assume the form via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.
