Juken Sentai Gekiranger (Werewolf Transformation)

Thanks to our friend Ian Ricky for suggesting and providing this video from one of the Super Sentai series (獣拳戦隊ゲキレンジャー), which was later adapted into Power Rangers Jungle Fury. The footage is assembled from episodes  22, 23, 24, 25, and 27.

Ian's description: "Gou Fukami  used an imperfect form of the forbidden Geki Waza, in an attempt to defeat Rio the way the Fist Sages had done to seal the Fist Demons long ago. But it failed and Gou had been wandering for fifteen years in his resulting werewolf form which he could not control."
