Search for the Spy! (スパイを探せ! Supai o Sagase!) is the third episode of Battle Fever J. It continues an introductory storyline that will ultimately lead to the introduction of the team's secret weapon as well as introduce the possibility of Secret Society Egos building something similar.
While the members of Battle Fever joke around in their base, Battle Japan, Den Masao, has been acting strangely aloof and disappears. Later, Tetsuzan Shogun arrives saying that the blueprints for Battle Fever’s giant robo look like they have been tampered with. Battle Fever searches for Masao, and find that he has been shopping blueprint photos around to a magazine editor. He is then referred to meet with a mysterious woman in a coffee shop interested in buying the photos. When he is ambushed by Egos, Battle Fever rescues him but accuses him of being a traitor! Only then do they discover, he has been shopping around fake blueprints to expose the Egos spies.
