Return of Ultraman

During a fight between the Monster Attack Team and monsters Takkong and Zazarn, Hideki Go, a young man chasing for his dream of becoming a professional racer, died saving the lives of a child and a dog...

Takkong appeared again! Go became overconfident after gaining the power of Ultraman and disobeyed the captain's orders, only leading to the escape of Takkong. Expulsed by MAT, he returned to Sakada Car Factory, but was welcomed coldly by Sakada

Go heard a monster's roar during a patrol over Mt. Kirifuki. However, the roar could only be heard by Go because of his extrasensory. Ueno, who was riding with Go, did not hear the sound and started an argument with Go.

Ancient Monster Kingsaurus III appeared near the No. 1 Nuclear Power Plant. Go fought as Ultraman but his super attack was not effective. The only way to defeat Kingsaurus III is to acquire a kick that could jump over the barrier made by the monster.

While Go and Kishida were arguing about how to deal with it, Underground Monster Gudon appeared in a quarry. On the other hand, Ancient Monster Twintail came out of the rock-like object, bringing panic to Tokyo's Shinjuku, the sub center of Tokyo.

After MAT's MN Bomb didn't work out, Commander Kishida decided to use "Spiner", a weapon with the power of a mini hydrogen bomb. Captain Kato strongly fought against the idea because if Sniper was used, Tokyo will be destroyed.

Go went hiking with the Sakada brothers and had plently of fun. The memorial photo they took showed there was a monster. It was Gorbagos, the monster with the ability of changing its skin color to camouflage itself.

Accidently, Go casted the X Bomb into the tail of Ghostron. X Bomb was a time bomb and there was only 10 hours left before its explosion. Out of all places, Ghostron decided to take a nap in front of the dynamite factory!

Go was sent on a mission to receive the high-spec monster detector developed by the technology division of MAT located in New York. Knowing that the mission was on the same day of Jiro's birthday, Minami substituted for Go and flew away by MAT Arrow.

Kids were excited about the giant dinosaur fossil discovered from the construction site, but the fossil was blown up by the site manager in a rush. Strong dissolver blew out from the fossil and melted the field workers.

A filming team met an accident during filming on location. Kishida was horrified, after he heard the accident was caused by the Yellow Gas, a secret weapon Kishida's father once helped develop for the Armed Forces of the Empire of Japan.

While MAT was under special training, a group of young men on motorbikes were attacked by monster Shugaron. They were mocking Shizuka, the only daughter of the famous painter Ushiyama, before being attacked. Is the monster Shugaron protecting Shizuka?

A vessel transporting gemstones was attacked by legendary monster Seamons and sunk into the sea. MAT started making an analysis of "The Song of Seamons" sung by Captain Takamura before the incident, hoping to get some clues.

After repulsing the giant tsunami created by Seamons and Seagorath, Ultraman had to retreat. The result of the analysis of "The Song of Seamons" proved the innocence of Captain Takamura, but he still faced difficulties returning to the society.

Jiro's schoolmate Shiro became a liar ever since his father died in an accident. He claimed that his father was killed by monster Eledortus, something that nobody believed in. At the same time, a monster with the ability of absorbing electricity appeared.

Saburo Matsumoto and Yukiko Ono grew up together, but Yukiko was going to be married. Saburo felt envious and planned to blow up the yacht in the middle of the shipboard party.

Terochilus ran away from the battle with Ultraman and headed towards the "Silver Castle", the nest built in downtown Tokyo by Terochilus. At the same time, Saburo escaped from the police, took Yukiko away from hospital and hid in the "Silver Castle".

The MAT Space Station and Captain Kaji, who is Captain Kato's close friend, was swallowed by the monster Bemstar. Kado gave out orders to attack Bemstar for avenge, but the Great Space Monster from the Crab Nebula is more troublesome than he'd imagined.

Jiro, who is looking after the school's rabbit with his friends during the summer vacation, discovered a meteorite. The meteorite was left at school, but later grew into an invisible giant monster.

Go was investigating the frequently occurred accidents of airplanes. The reason seemed to be the overconcentration of the geomagnetic field in Kumazawa Dam. Monster Magnedon appeared near Kumazawa Dam, and was defeated by MAT.

When Captain Ibuki finally gets his vacation for the first time in three years, he goes on a trip with his wife Yoko and daughter Minako. However, Alien Grotes sees this as an opportunity to kill Ibuki and destroy MAT.
