GoGo Brace (ゴーゴーブレス Gō Gō Buresu): The transformation device of the team that were stored inside Mint and given to the Tatsumi Siblings by their father. To be activated, the wearer pulls back a tab that flips the faceplate on the brace outward, and then presses a button. The transformation call is Suit Up! (着装 Chakusō). It also acts as communicator and used to activate the Life Bird, Grand Liner or 99 Machines.
The GoGo Brace stores the ability to activate the Anti-Hazard Suit used to become a member of GoGoFive. The braces are locked on only to the five Tatsumi siblings who were programmed to activate them and are the only ones who can access the Anti-Hazard Suits. If the "powers" become separated from the Ranger and end up in another, the person will not be able to use the GoGo Brace due to the unique signature that only reacts to the one programmed to use it; such as when Matsuri Tatsumi loses her "abilities" to Mizuki Kido: Matsuri may not be able to transform due to losing her "powers", but Mizuki can't use the GoGo Brace because the GoGo Brace is programmed to only be used by Matsuri. However if the body and mind are separated, then whoever possesses the body can likewise transform, such as when Garubaria enters into the body of Matoi Tatsumi and thus can become GoRed as long as he is in that body.
The GoGo Brace's technology is centered around a specific chip that is used; when it is damaged, it must be repaired for it to be fully usable once again and can be completed by the GoGoFive members in case of emergency.
At the climax of the Legend War, the GoGo Braces were made redundant when GoGoFive 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 GoGoFive 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.
