JFO

The JFO (Japanese Flying Object) is a spaceship made by Koji Kabuto to replace the TFO after it was destroyed. Compared to its predecessor it is triangle shaped and only appeared for a single episode. It was more aerodynamic and included a missile system. But like the TFO it was destroyed in battle with a Saucer Beast. The JFO first appears in Episode 30 of Grendizer

Trivia

 * The JFO was not officially named until it was revealed in a magazine ad, and was known as Koji's Disc at the time.
