―Ultraman Jack as Hideki Go, Deathrem's Plot

Ultraman Jack (ウルトラマンジャック Urutoraman Jakku) is the fourth Ultra Warrior to arrive on Earth, debuting in Return of Ultraman. To protect the Earth from rampaging monsters and alien invaders, he becomes one with Hideki Go, who joins the defense team MAT. Jack's signature weapon is the Ultra Bracelet, which he received from Ultraseven.



When Tsuburaya created Return of Ultraman, they had originally drafted for the star Ultra Warrior to be the original Ultraman, but before the show aired it was decided for the "Returning Ultraman's" identity to be left ambiguous. Furthermore, when the Original Ultraman and Ultraseven made an appearance halfway through the show, the situation became more complex. The third Ultra Hero went on through the 70's with being referred to as "Returning Ultraman" etc. It wasn't until Ultraman ZOFFY: Ultra Warriors vs. the Giant Monster Army in 1984 that the then president of Tsuburaya Productions, Satsuki Tsuburaya officially gave the name Ultraman Jack, which was a leftover prototype name for Ultraman Taro, as the Ultra Warrior's official name. This name was decided upon through a contest held by Tsuburaya and Bandai, which was held after licensing issues over the Ultraman's name. The name comes from the western fairy tales of "Jack the Giant-Slayer" and "Jack and the Beanstalk".

Before his name's official reveal, he was called many titles in addition to the "Returning Ultraman":

  • In the Malaysian dub of Ultraman Ace episode 14, Ultraman Jack is called "Ultraman Shinian".
  • In Ultraman Taro and Ultraman Leo, Jack is called "Shinman" (New Ultraman - Shin Urutoraman)


As the next generation after Ultraman and Ultraseven, Tsuburaya Productions made Jack's design similar to the 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 patterns on Ultraman Jack's silver suit are 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 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.


Return of Ultraman

Jack merging with Hideki Go

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, 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 earlier. 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 Arstron, a monster that was attacking a mountain village. All Monsters Attack After Jack defeated Arstron, Go applied for MAT and quickly passed their tests with flying colors. Takkong's Big Counterattack

Ultraseven giving Ultraman Jack the Ultra Bracelet in episode 18

After learning to control Jack's power while defeating Takkong, Go, 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. Ultraseven Arrives! 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 monster 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 threaten them. Jack put his life on the line to save Go's friends, and after impaling Bat with the Ultra Cross, Zetton was quickly taken down. The 5 Ultra Oaths (episode) 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 Jack and the Ultra Brothers joined Kotaro for some lunch on Earth but then Zoffy told them about Alien Temperor and said that Temperor will turn Earth into a warzone if the Ultra Brothers fight him so they let Ultraman Taro fight Temperor alone only for Taro to nearly dying. Go swaps bodies with Tado Nambara to make sure Taro won't depend on the Ultra Brothers. Ace and Ultraman Jack became extremely worried for Taro and wanted to help him, unlike the other Ultra Brothers. However after a memorial was held for the ZAT members that "died", Kotaro meets the disguised Ultra Brothers after he runs out of ZAT base. Then Kitajama and Vice Captain (Ultraseven and Ultraman) tell Kotaro that they'd rather wait on the Ultra Brothers which angers Kotaro and fights Temperor.

After Alien Temperor's first death, the Ultra Brothers returned to their human forms and met up with Kotaro. Although Ace and Jack show regret for not helping him, Kotaro becomes arrogant and cocky about killing Alien Temperor saying it was a piece of cake and Kotaro heads back to ZAT. The Ultra Brothers became very disappointed and angered by Kotaro's attitude, especially Ace. As Zoffy breaks the news that Temperor has revived, the Ultra Brothers go into their ZAT human forms and launch an attack on Temperor with the ZAT attack planes only for Kotaro being very cocky and just uses a car to make Temperor dizzy and run away. The Ultra Brothers agree if Kotaro is still cocky he may not be an Ultra Brother.

As Temperor's new plot works, he captures Kotaro in his tiny cape and is prepared to kill him. The Ultra Brothers as ZAT fire the Strium Beam from the plane, only for Temperor to not have a scratch and nearly kills Kotaro. After a chat between Kotaro and Zoffy as Dr. Ohanti the Ultra Brothers are exposed by Temperor and must take cover. At first the Ultra Brothers (including Kotaro) disguise as volleyball player only for Temperor to instantly expose them. Kotaro, however, manages to let Kittari (the son of Dr. Ochanti) use the Ultra Balls that were used to stop Temperor the first time again and this time all of the Ultra Brothers finally fight and managed to kill Temperor and his ship. The rest of the Ultra Brothers officially call Taro an Ultra Brother and wave him goodbye and remind Taro of teamwork. The Last Day of the Six Ultra Brothers!

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 Triple Beam 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 Babarue. 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 Babarue, dismayed at the return of Astra, fought both of them, hoping to retrieve the key. While Dan and the MAC distracted Babarue, Astra tried to return the key to the Land of Light but was stopped by Babarue'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 Babarue with his kick and Astra managed to return the Key to its rightful place. Battle! The Leo Brothers vs. the Ultra Brothers! The Leo Brothers and the Ultra Brothers, Time of Victory

The Ultra Brothers then transformed once again. The brothers fought for about 1-2 minutes with their low energy, despite this, but because of their limited power, they were defeated by Guts and Alien Nackle, and they were all crucified in crosses above Kobe's sea where Yapool and U-Killersaurus were sealed. Guts and Nackle then threw Mebius away and drained the remaining energy from Ultraman and the other Ultra Brothers.

While seeing his fellow Ultras in pain, Mebius found new strength after being encouraged by a young boy whom he befriended prior to the battle, and the teachings of the four Ultra Brothers, he then returned to the fight, with great courage. He managed to destroy Alien Guts, and freed the Ultra Brothers, but not in time. U-Killersaurus and Yapool where already freed from their prison. Once freed, the Yapool killed Alien Nackle and upgraded the U-Killersaurus to U-Killersaurus Neo.

Jack also appears in Ultraman: Monster Crisis, as the main protagonist.


  • Originally, Ultraman Jack was meant to be Ultraman, whom would have returned to Earth as referenced by the show's name was Return of Ultraman but this decision was scrapped and he was made as a separate character out of respect to the late Eiji Tsuburaya, who passed away in 1970. However, the name of the show still remained "Return of Ultraman".
    • In the originally concept for Return of Ultraman, Hideki Go was meant to use the Beta Capsule to become Ultraman Jack, like how Shin Hayata transforms to Ultraman but this decision was also scrapped.
  • Jack's name change from "New Ultraman" caused outrage among older fans back in the day. This complaint has faded away in the present time.
  • Jack is the first Ultra Warrior not to have his series named after him, due to the fact that he was only given his official name long after his series ended.
  • Jack is the first instance of an Ultra Warrior being afraid to fight a monster (Alien Bat's Zetton).
    • Jack was also the first Ultra Warrior not to fight an evil clone or imitation of himself in his original series.
  • When Jack used ray attacks, the sound effect of Ultraseven's Emerium Beam was heard instead of Ultraman's Spacium Beam. However, in Ultraman Fighting Evolution 3, Jack used Spacium Beam's sound effect instead.
  • When Ace Killer removes Jack's Bracelet, Jack becomes weakened. It is never explained why or how this weakens Jack, as Ace Killer is never shown taking energy from him.
  • Although Jiro Dan, the actor who portrayed Hideki Go, is Jack's current voice actor, Jack's grunts still reuses modified and high pitched version of Ultraman's produced by Masao Nakasone. However, Ultraman Mebius and Mega Monster Battle: Ultra Galaxy Legends The Movie are the only time Jiro Dan's grunts were used for Jack.
  • In the 52nd episode of Ultraman Taro, Ultraman Jack was portrayed by the same suit used for Ultraman with more silver than red, and also red gloves and boots. He also didn't have his Ultra Bracelet. Also, Jack's Color Timer's sound was a high pitch version of Taro's.
  • In Ultraman Leo, Jack is seen wearing the Taro Bracelet instead of the Ultra Bracelet.
