Ultraman Jack

is the main character of The Return of Ultraman. A 17,000 to 19,000 year-old Ultraman who was originally named "New Ultraman" (新ウルトラマン, Shin Urutoraman?), or just "Kaettekita Ultraman" (帰ってきたウルトラマン?), after the show's title. In the 1970s to early 1980s, Tsuburaya and Bandai held a contest for children to pick a new name for the character due to licensing issues. Ultraman Jack's series was created after the death of Eiji Tsuburaya.

Physiology
While nearly identical in appearance to the original Ultraman, the red pattern on Ultraman Jack's silver suit is slightly different, and he can be distinguished by his shorter "pants," fuller "sleeves" and "kneepads," and pinstripes along the red areas.

Also of note is that Ultraman Jack is one of the few Ultras who does not require a transformation device for their human host. Hideki Go, the human host for Ultraman Jack, simply raises his hands to transform at will when Ultraman Jack signals him to do so, or sometimes even against his will in a very desperate situation. Also, there are times when Hideki Go tries to transform, only to have the process blocked due to Ultraman Jack refusing to transform under the circumstances.

Character Design
As the new generation after Ultraman and Ultraseven, Tsuburaya Productions made the design similar to Original Ultraman. Some changes were the Ultra Bracelet, the stripes on his body, and his color timer was modifed.

The Return of Ultraman
A racer named Hideki Go was caught in the middle of the battle between two monsters, and was mortally wounded when rescuing a young boy, eventully dying as he arrived at the hospital. Just minutes before they removed the body from the room, Ultraman Jack came to him much like Ultraman did to Shin Hayata five years ago. Impressed by his previous act of heroism, Jack had made Hideki Go his host and revived him. Shortly afterwards, Go used his power unknowingly for the first time to defeat Earthtron, a monster that was attacking a mountain village. After Jack defeated Earthtron, Go applied for MAT and quickly passed their tests with flying colors.

After learning to control Jack's power while defeating Takkong, Goh, Jack, and MAT would continue to fight monsters and aliens for nearly a year. After a defeat from Bemstar, Ultraseven gave Jack a new device called the Ultra Braclet which has helped him even further. Over time Jack's skills and strength increased. When the alien known as Bat entered one of Go's dreams, Jack began to have nightmares about Zetton, a robot that nearly killed the original Ultraman. Once Bat made himself known, he used a second Zetton to terrorize Tokyo while keeping Go's friends hostage by having Zetton hold them. Jack put his life on the line to save Goh's friends, and after impaling Bat with the Ultra Lance, Zetton was quickly taken down. This proved that Ultras can take down Zetton. Jack then flew back to M78 to aid the others against Alien Bat's invasion. Afterwards, Jack returned to Earth to help other Ultras in their time of need.

Ultraman Jack is one of the few Ultras to remain in contact with his human host. Hideki Go still serves as a vessel for the mighty alien warrior, as seen in the Ultraman Mebius series and movies.

Ultraman Ace
Ultraman Jack reappeared in Ultraman Ace episodes 1,13,14, 26 and 27.

Jack first appeared with the other Ultra brothers to rescue Hokuto seiji and Yuuko Minami after they were dead

Jack also went with the Ultra brothers to planet golgatha and found out that there was his name on a cross when some cold wind managed to get the Ultra brothers himand the rest of the ultramans gave enough power to Ace and Ace flew back to Earth.

Ultraman Taro
Ultraman Jack reappeared in episode 1, 25, 26, 27, 40, and 52. Hideki Go also reappeared along with the Ultra Brothers in episode 40.

Ultraman Leo
Ultraman Jack reappeared in episodes 34, 38, and 39.

Ultraman Jack went to get Ultraseven Ultra eye but he was stopped by ashuran and JAck couldn't fight him with the Capsule monster sevengar so he fled to Earth and gave Sevn Sevengar and went back to Land of Light to fix it.

The evil Alien Babalou managed to freeze Astra, Ultraman Leo's younger brother, and copied him to fool the Ultras. Astra flew to the Land of Light, and after being followed by the Ultra Brothers (Ultraman, Ultraman Zoffy, Ultraman Jack, and Ultraman Ace), he managed to steal the Ultra Key. The Ultra-homeworld fell out of its orbit, and was heading toward a collision with the Earth. When he was going to escape, he was stopped by Ultraman, and the two had a short fight, but "Astra" escaped and flew to Earth.

The other brother assisted the defeated Ultraman. He told them that it was not Babalou who stole the Ultra Key, but Astra. The Ultras were shocked and chased him all the way to Earth but not before informing Ultraseven that Astra took the Ultra Key. Dan Moroboshi told Gen Otori about the incident. Gen was shocked, and after "Astra" arrived on Earth, Dan tried to stop him using his Ultra powers as the Ultra Brothers landed on Earth. Thinking that harm might come to his brother, Gen would not be held off by Dan and the two started to fight. The Ultra Brothers fought the fake Astra in hope to retrieve the Ultra Key.

Ultraman managed to hurt Astra but he managed to get up. Dan Moroboshi beat Gen Otori unconscious and he began to use his Ultra powers to weaken Astra. Howver, Gen recovered and beat Dan rendering him unconscious. He transformed into Ultraman Leo. After a hard battle against the four Ultra Brothers, he helped the beaten Astra, asked him what he did but Astra did not answer. He begged the brothers to stop. They denied his request and told Leo that the consequence of stealing the Key was the collision of the Land of Light with Earth.

At that same moment, the Land of Light was getting closer to Earth, and natural disasters started to occur. Massive earthquakes created gigantic fissures on the ground. The Ultra Brothers renewed their attack against Leo and Astra. After a short battle, the Ultra Brothers had no choice but to use their Specium Rays against Astra. Leo, however, shielded Astra with his body, causing serious damages and fell to the ground.

"Astra" mocked the Ultra Brothers and was about to shoot them using the Key. Suddenly, a mighty thunder and lightning from the sky hit "Astra", knocking him to the ground. The Ultra Key broke into two pieces. Out of the blue, Ultraman King appeared, and after saluting Zoffy, he told the Ultras to see the true nature of "Astra". He fired his ray to "Astra", removing the disguise to reveal Alien Babalou. Ultraman King ordered the brothers to return to the Land of Light while Leo, recovered, flew to where the real Astra was imprisoned. Returning to Earth, the UN was about to launch a rocket to destroy the in-coming planet while Dan and the MAC prepared for a counter-attack. Leo and Astra, reunited, used their power to restore the key. Alien Babalou, dismayed at the return of Astra, fought both of them in hope to retrieve the key. While Dan and the MAC distracted Babalou, Astra tried to return the key to the Land of Light but was stopped by Babalou's chain. The more powerful Leo assisted and held the alien long enough for Astra to fly off to the planet of the Ultras. Leo killed Babalou with his kick and Astra managed to return the Key to its rightful place.
