Arms
Like the Armored Riders and his fellow New Generation Riders, Kamen Rider Proto Zangetsu Shin's forms are called Arms (アームズ Āmuzu). His Genesis Driver announces "Soda" (ソーダ Sōda) before every transformation.

By pushing the Genesis Driver's Seaboll Compressor into the Energy Lockseed after transforming from one to two times, Tyrant can activate one of two finishing moves based on his current Arms form: Squash (スカッシュ) or Sparking (スパーキング). In addition to the Genesis Driver's finishing moves, Tyrant can perform a Sonic Volley (ソニックボレー) finishing attack by inserting an Energy Lockseed into the Energy Drive Bay of his Sonic Arrow.
