A group of scientists and reporters have went on an expedition to Oilis Island, and find a rare Miloganda plant, but were almost attacked by a huge green plantlike monster (known as Greenmons), which they shoot to death. But one month after their return to Japan (with the Miloganda plant at a greenhouse lab), the very same Greenmons murders all of the expedition members, except one: Photographer Setsuko Hamaguchi, who the Science Patrol suspect will be the monster's next target and place her under protective custody. They also find that radioactive energy (even their Superguns and Arashi's Spider Shot gun) can make the monster stronger . . . and grow! What is the connection between the Miloganda plant and Greenmons? Will Ultraman stop the green terror from causing any more destruction?

A seven thousand year old mummy is awakened by scientific experiments and it goes on a rampage. When finally cornered, it summons an enormous, four-legged dragon so powerful that only Ultraman stands a chance of defeating it.

A pair of unusual meteors discovered by an American explorer fuse together after being exposed to a special beam. They mutate into a bizarre fourth-dimensional monster capable of warping reality as we know it. Can Ultraman overcome this psychedelic menace in time to save the day?

The opening of the Science Patrol's new undersea science base is marred by tragedy, as a mutant Narwhal damages the base and air is now on short supply. Hayata and the others must make a daring rescue to save the people trapped on the base while avoiding the monster's deadly attacks.

The Science Patrol discovers that the culprit behind a baffling series of volcanoes, earthquakes and other natural disasters is actually a giant monster. When it heads towards Tokyo, only Ultraman can stop it.
