|This article is about a/an changer in Chouriki Sentai Ohranger.|
Power Brace (パワーブレス Pawā Buresu): The Ohrangers' changing device. One piece is worn on each wrist. The right-armed piece, called Energy Brace (エネルギーブレス Enerugī Buresu) has a Storage Crystal, the source of the Ohrangers' Tetrahedron Power, attached to it. The Storage Crystal is also placed inside of the cockpit of Ohranger Robo in order to pilot it. The left piece, called Back Brace (バックブレス Bakku Buresu), also can work as a communication device to contact U.A.O.H.'s home base, and to contact the other Rangers. By using the henshin call "Super-Powered Transformation!" (超力変身！ Chouriki Henshin!) and connecting their braces, the user transforms into an Ohranger. It cannot be used unless the user is suitable for the Super Power. Both sides of the Brace must be held in order to make proper communication or transformation with the other Rangers and base.
The transformation sequence during OhRed's first transformation was shown with the green wire-frame wrapping Goro's body and glowing after he detached both braces and the suit started materializing, showing a closeup of his hand wrapped in the wire-frame when the suit materializes (the footage of the glove materializing before the upper suit forming was used in Zeo) and then going into the materializing of the upper suit (which in the later episodes would be used as stock footage after the shot of the two braces connected glowing).
Unlike most other Sentai Changers, the Power Braces are not replaceable due to the unique Storage Crystals they hold.
At the climax of the Legend War, the Power Braces were made redundant when the Ohrangers 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 Ohranger 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.
- The Power Brace (and King Brace likewise) are the first transformation devices in Super Sentai where "Henshin" is used as part of the transformation phrase; this word is usually used as part of the transformation phrases for Kamen Rider. This would be later used for the MagiPhone in Mahou Sentai Magiranger 10 years later.
