|This article is about a/an changer in Kagaku Sentai Dynaman.|
Dyna Brace (ダイナブレス Daina Buresu): The team's transformation device. To transform, the team calls their name (team name for the whole group, individual names for individual members). The brace is voice-activated and must be spoken into to fully transform; this becomes a slight plot point when a scheme prevents the team from transforming due to not being able to say the transformation phrase.
Like the previous brace, the transformation device is merely the means to access the power and does not contain the suit or any aspect regarding the power itself. If one is destroyed, another one can be acquired for the user to ultimately regain their abilities to fight as a Dynaman.
The Dyna Brace is likewise the means to activate the auto-control of Dyjupiter to allow the carrier to be summoned to them. While typically seen for giant fights, this becomes an important factor to allow Dr. Yumeno and the carrier to reach the Millennium Cave to destroy the doors and free the team during the final Jashinka battle.
At the climax of the Legend War, the Dyna Braces were made redundant when the Dynamen 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 Dynaman 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.
