Egos' Hellish Cooking (エゴスの地獄料理 Egosu no Jigoku Ryōri) is the fifteenth episode of Battle Fever J. It is notable for two major changes to Battle Fever's finishers: first their Penta Force switching from a cannon to a spinning boomerang-like projectile; and more notably the first usage of Battle Fever Robo's Denkouken as the main team finisher with the introduction of its finishing move: the Chinese Bamboo Slice.
