[2] While reading the Galactic Bible, the space hermit Edjinn learns of a shocking prophecy: When the dark god Satan Goth awakens, the universe will be ravaged by giant monsters filled with rage.

Juspion travels with his friends Anri the android and Miya the alien across the galaxy in his battleship Daileon to confront Satan Goth and his army.

Eventually, Juspion land on Earth, which, it turns out, is a prolific source of MegaBeasts (it is explained that the dinosaurs were part of that group), and many of them are still asleep in various locations.

Amongst Juspion's arsenal, there is his Metal Tech Suit armor, made of a very rare mineral called Edjinium and equipped with a visor called Sensor Eye that can scan the environment with x-ray and night vision, and his Plasma Blazer Sword, which can be contracted for storage and can be infused with the plasma during combat, and his Beam Scanner Gun.

Based on the silver Super Planetary Battleship Daileon (超惑星戦闘母艦ダイレオン, Chō Wakusei Sentō Bokan Daireon), Juspion travels across worlds to pursue Satan Goth.
