Beast-Fist Transformation Brace GongChanger (獣拳変身ブレスゴングチェンジャー Jūken Henshin Buresu GonguChenjā?) is a wolf-themed transformation device developed by SCRTC for Gou Fukami as an alternative to the Beast-Fist Henshin GekiChangers, which proved incompatible with his unique Violet Fierce Ki. Following his transformation call, "Echo! Howl of the Beasts! Beast On!" (響け！獣の叫び！ビースト・オン！ Hibike! Kemono no sakebi! Bīsuto On!?), Gou transforms into GekiViolet, using the GongChanger's gong-inspired sub-theme as medium for his Gekiwaza attacks.
