MegaBeast Investigator Juspion
A tokusatsu series about a hero fighting corrupted MegaBeasts.
MegaBeast Investigator Juspion (also called Space Wolf Juspion or just Juspion) is a Japanese tokusatsu series belonging to the Metal Hero Series franchise. Toei Company produced it, and it aired from 15 March 1985 to 28 February 1986, totaling 46 episodes. Toei refers to the show as Juspion for distribution.
The story begins when the space hermit Edjinn reads the Galactic Bible and learns a prophecy: the dark god Satan Goth will awaken, unleashing giant monsters filled with rage across the universe. When Satan Goth appears, Edjinn sends Juspion—whom he has been training—to stop him and fight the corrupted MegaBeasts. Juspion travels with his friends Anri, an android, and Miya, an alien, aboard the battleship Daileon. They eventually reach Earth, which turns out to be a major source of MegaBeasts (the dinosaurs were part of this group), with many still dormant in various locations.
Juspion’s arsenal includes the Metal Tech suit, made from the rare mineral Edjinium, with a Sensor Eye visor offering x-ray and night vision. He wields a Plasma Blazer Sword that can be contracted for storage and infused with plasma in combat, plus a Beam Scanner Gun. His ship Daileon houses the Super Planetary Combat Tank Garbin (which splits into a tank and jet) and a motorcycle called Iron Wolf. Daileon itself transforms into a giant robot, the Super Planetary Battle Giant Daileon, often Juspion’s final weapon against MegaBeasts.
The Daileon crew includes Juspion, an orphan raised by Edjinn until his quest begins. His name combines “Justice” and “Champion.” Anri, an android created by Edjinn, is immune to evil powers. Miya is a baby alien found on planet Beezee after her parents were killed by hunters; she is friendly, intelligent, and a good cook, learning to speak from episode 22 onward.
Vehicles include the motorcycle Iron Wolf and the tank Garbin, which splits into a tank with twin drills and a jet.
Allies include Edjinn, a hermit and scientist who guards the Galactic Bible and survives the series finale, last seen in the final episode. Boome-Run, a medical student turned U.S. Marshal, seeks revenge for his brother’s death, fighting with twin boomerangs (his name blends “Boomerang” and “Home Run”).
