The Transformation Cellphone Zyuoh Changer (変身携帯ジュウオウチェンジャー Henshin Keitai Jūō Chenjā, Beast king Changer) is the Rubik's Cube-based transformation and summoning device of Zyuohgers. By twisting the upper section, the Zyuohgers are able to complete images on the Changer's faces, allowing them to perform different functions. Each function, when the Zyuoh Changer is opened, is shown in the top of the "screen" above the eagle's wings. The normal, unmatched form shows a green telephone reciever which enables the Zyuoh Cube to be used as a means of communication.
