Final Ep.: The Symphony of the Heroes

The Symphony of the Heroes is the fifty-second and final episode of Battle Fever J.

Synopsis
With Hedda destroyed, Satan Egos vows to use his final strategy. First, they create an earthquake machine that begins to wreak havoc on Japan. Then, while Kyosuke and Shiro are investigating, a mysterious woman named Ichijoji Ayako requests a clandestine rendezvous. Masao meets her in the park and she shows his photographs of Egos headquarters and the earthquake machine, offering to sell a map to the location for 1 billion yen. When they go to make the exchange, Egos attacks, and they determine that the woman is really Sarome in disguise. In the hospital, Sarome claims that Egos was going to cause a massive earthquake to destroy all of Japan, and that she wanted to escape with her life to South America. She hands over a microfilm hidden in her tooth that leads Battle Fever to Egos Headquarters. After battling their way in, they meet Satan Egos face-to-face for the first time. It turns out to be a trap, as his final strategy is to Battle Fever into the Monster Making Capsule, and turn them into the ultimate kaijin. Just before they melt away, they destroy the heart of the Monster Making Capsule and are freed. Satan Egos leaves, destroying the Egos headquarters (and crushing Sarome). Ouside, he begins to use all his power to unleash Armageddon. Battle Fever uses the Battle Fever Robo with all of their power to finally destroy him once and for all. Finally triumphant, they ride off into the sunset.
