Ultraman Jack (ウルトラマンジャック Urutoraman Jakku?), formerly known as "New Ultraman" (新ウルトラマン Shin Urutoraman?), Ultraman ll (ウルトラマン
When Tsuburaya created Return of Ultraman, they had originally drafted for the star Ultra Crusader to be the original Ultraman, but when the show aired they left it ambiguous to who the "Returning Ultraman" really was. Further more, when the Original Ultraman and Ultraseven made an appearance half way through the show, the situation became more complex. Jack went on through the 70's with being referred to as "Returning Ultraman" and ect. (see above). It wasn't until Ultraman Zoffy: Ultra Warriors vs. the Giant Monster Army in 1984 that the president of Tsuburaya Pods, Satsuki Tsuburaya officially gave the name Ultraman Jack, which was a left over prototype name for Ultraman Taro, as the Ultra warrior's official name.
As the next generation after Ultraman and Ultraseven, Tsuburaya Productions made Jack's design similar to Original Ultraman. Some of the changes included were the Ultra Bracelet, the stripes on his body, as well as modifying his color timer.
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 "knee pads," and pinstripes along the red areas.
Ultraman Jack is one of the few Ultras who does not require a transformation device. Hideki Goh, 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 Goh tries to transform, only to have the process blocked due to Ultraman Jack refusing to transform under the circumstances.
Return of UltramanA racer named Hideki Goh was caught in the middle of the battle between two monsters, and was mortally wounded when rescuing a young boy, eventually 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 Goh his host and revived him. Shortly afterwards, Goh used his power unknowingly for the first time to defeat Arstron, a monster that was attacking a mountain village. After Jack defeated Arstron, Goh 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 Bracelet which has helped him even further. Over time Jack's skills and strength increased. When the alien known as Bat entered one of Goh's dreams, Jack began to have nightmares about Zetton, a monster that nearly killed the original Ultraman. Once Bat made himself known, he used a second Zetton to terrorize Tokyo while keeping Goh's friends hostage by having Zetton threaten 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 Goh still serves as a vessel for the mighty alien warrior, as seen in the Ultraman Mebius series and movies.
Jack also went with the Ultra brothers to the planet Golgatha and found out that there was his name on a cross. Yapool summoned Barabas to destroy Earth as the Ultras realized it was all a trap. Ace tried to return to Earth, but cold winds on the other planet weakened the Ultra brothers. The rest of the Ultra Brothers gave enough power to Ace to fly back to Earth, only for them to get tied on their crosses. Ace Killer appeared and absorbed the Ultra's powers, and took Jack's Ultra Bracelet. Ace came back but had a tough battle with Ace Killer, so they give Ace their remaining energy from their color timers, Ace was able to defeat him with Space Q. They went back to M78 while Ace went back to Earth to fight Barabas.
When Ace summoned the Ultra Sign, Jack and the Ultra Brothers flew to Earth, and were shocked to see that Ace had turned into a Jade Statue. Alien Hipporito suddenly appeared, and they were prepared to fight, but Alien Hipporito trapped Ultraman, and Zoffy in chambers while Jack and Seven dodged away from it. While Seven was fighting the Alien, Jack tried to get Ultraman and Zoffy out, but was trapped to after attempting to get them out with his Ultra Bracelet. Later, after they were all turned to statues. Ace "de-turn" him and the rest of Ultra Bothers and brought Father back to the land of light as he gave all his energy to Ace to save him.
Ultraman Jack, with the other Ultra brothers, revived Kotaro after he died in a plane crash by Astromons.
After Taro retreated after being hurt by Mururoa & went to the Land Of Light, Jack and the Ultra Brothers were waiting for Taro when he Arrived. They all went to retrieve the only item which could clear the space monster's smoke, the Ultra Bell. Taro and the Ultra Brothers arrived, pulling the Ultra Bell with them. The legendary device’s tolling cleared away Mururoa’s darkness in an instant! After Mururoa was defeated, Taro returned the Bell.
In Episode 29, After Bemstar was revived by Yapool, ZAT were watching footage of Ultraman Jack fighting Bemstar to defeat Bemstar the same way Jack did.
Ultraman Jack joined the battle against Alien Temperor after visiting Earth and Taro with the Ultra Brothers. Ultraman Jack fought Tyrant on Jupitor after Zoffy, Ultraman, and Seven were defeated. As Jack was defeated, he sent the SOS, but Tyrant destroyed it and went on.
Jack fought Dorobon in space after he escaped from The Space Prison of Nebula M78. Jack used his Cinerama Shot on him, but Dorobon blocked it with his weapon and defeated him in the chaos of the chase, landing on Earth. When Hideki Goh transformed into Jack, Dorobon gave him the ship with Hitomi held captive. While fighting the monster, Dorobon took off his color timer, causing Ultraman Jack to deflate like a balloon. Taro saved him by putting his color timer back on him, and they left for M78.
Ultraman Jack went to get Ultraseven's Ultra Eye but he was stopped by Ashuran. Jack couldn't fight him with the Capsule monster, Sevengar, in hand, so he fled to Earth and gave Seven's human form Sevengar to fight Ashuran. Sevengar was winning, and was about to finish Ashuran off, when his time limit ran out of time. Later, he and Leo fought and defeat Ashuran. He took Seven's Ultra Eye and went back to Land of Light to fix it.
When The evil Alien Babarue managed to trap Astra, Ultraman Leo's younger brother, and transformed into him to fool the Ultras. Astra flew to the Land of Light, and after being followed by the Ultra Brothers (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 Ultra Brothers assisted Ultraman & 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. However, 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 damage and fell to the ground unconscious. 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, after recovering, 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, hoping 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.
Six Ultra Brothers vs. The Monster Army
Ultraman Jack reappeared in the film 6 Ultra Brothers vs. The Monster Army. After Piko was killed by some robbers, Mother of Ultra took him to the Land of Light to revive him. During the resurrection process, the Ultra Brothers were present, and using their energies, they transformed Piko into the monkey god, Hanuman.
Many moments later, a Thai base was trying to launch some missiles to the sky, because it would stop the worldwide drought, and cause rain. A missile was shot, it exploded in the sky, and it caused rain, as expected, but as the second missile was shot, it had a problem, and after failing to blast off, it blew up, causing a chain reaction with the other missiles, causing an apocalyptical event, and five monsters(Gomora, Tyrant, Dustpan, Astromons and Dorobon) rised from the Earth, and started causing chaos. Hanuman appeared to fight the monsters, but after receiving too much damage from them, the Ultra Brothers suddenly appeared from the sky, and they all start fighting the monsters. After they were all defeated, Gomora, who was unconscious, wakes up, and after climbing a mountain, releases a rainbow beam, that caused catastrophic natural disasters, Ultraman and Hanuman were trying to stop him, but the beam was too powerful, and they couldn't get close. Suddenly the other Brothers arrive, and managed to interrupt Gomora's beam, and after Gomora was defeated, peace was reigning again, and Hanuman said good-bye to the Ultra Brothers, who flew back to the Land of Light.
