Kyojuu Tokusou Juspion was originally broadcast from March 1985 to March 1986 (46 episodes). The name “Juspion” is a portmanteau of “Justice” and “Champion”. Kyojuu Tokusou Juspion is the only Metal Hero series to focus on giant robot combat.

The series focuses on Ejin, who whilst reading the Galaxy Bible, learns of a shocking prophecy: When the dark god Satan Gorth awakens, the universe will be ravaged by giant monsters filled with rage. After Satan Gorth appears and the prophecy is set in motion, Ejin orders Juspion, who Ejin has been tutoring, to stop him and combat the corrupted Megabeasts!
