Beast-Fist Henshin GekiChanger (獣拳変身 ゲキチェンジャー,
Jūken Henshin GekiChenjā?): A three button, two piece henshin device created by SCRTC to use the Fierce Ki of its wielder as a power source. It also can store a number of things including weapons in a pocket dimension. The changer is attached to the wrist and knuckles of the wearer. By forming a
Wushu hand formation and using the henshin call "Boil! Power of the beasts! Beast On!" (たぎれ！獣の力！ビースト・オン！,
Tagire! Kemono no chikara! Bīsuto On!?) (although simply saying "Beast On!" will suffice), the user transforms into a Gekiranger.
