|This article is about a/an changer in Chikyuu Sentai Fiveman.|
V-Changer (Vチェンジャー Bui Chenjā): Fiveman's transformation and communication devices. The individual Fivemen transform by shouting out their code names, while the gathered team shouts the team name. Gaku, Ken, and Fumiya have V-Changer Braces (Vチェンジャーブレス Bui Chenjā Buresu) (wristband changers). Kazumi and Remi have V-Changer Compacts (Vチェンジャーコンパクト Bui Chenjā Konpakuto) (pendant necklace changers). The V-Changer Braces must be fully removed from the brace into a male Fiveman's hand to be used; while the V-Changer Compacts can transform without special methods.
The transformation into Fiveman occurs due to a special "energy charge" within the V-Changers; this energy is required for any of the Hoshikawa siblings to change into their Five Suit. The energy can be stolen either directly from a Fiveman or mid-transformation, allowing for something else to become Fiveman. When something else is using the Fiveman powers, the V-Changer is useless until the power is deactivated from the one using it and the energy is recharged within the V-Changer itself.
The color of the V-Changer Braces for the male Fivemen is silver but once the brace fully detaches from their wrists, the color was black beneath the brace before the transformation and the color of the V-Changer Compacts for the female Fivemen are golden yellow.
At the climax of the Legend War, the V-Changers were made redundant when the Fivemen sacrificed their powers with the rest of the first 34 Super Sentai to destroy the invasion force of the Space Empire Zangyack. Resurfacing as Ranger Keys, the Fiveman powers would be used by the Gokaigers to assume their forms via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.
