The Ultraman

The Terrestrial Defense Force forms a Science Guard Party in order to investigate the cause of mysterious phenomena.

Jonias, a new Ultraman from U-40, merges with young Science Garrison member Choichiro Hikari to defend the Earth.

Hikari encounters monster Mikonos while investigating an unidentified flying object, then transforms into Joneus and drives it away. Later, a TV station receives some film that was shot of the battle. The rest of the film depicts Ultraman's Secret. Hikari tracks down the man who delivered the film, and it turns out to be a trap set by Space Ninja Alien Baltan.

Investigators visit ancient ruins on Tamara Island, and spot Monster Dolfiego in an underground cavern. Of the group, three people are brainwashed by Dolfiego and then begin firing mysterious rays and destroying things. The Science Guard Party arrives on the scene, but Dolfiego, speaking through the three, demands that they leave.

Several thousand trees disappear from the forest in a single night; in an underground cave they find Toughgilas.

As people evacuate from a tsunami caused by an earthquake in the Pacific Ocean, a mysterious flying object appears and rains down fire.
