==Conception==
===Etymology===
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, with the new Ultra now separate from his predecessor.
Throughout the 1970's and into the 1980's, this third Ultra would go by various fairly non-descript names, most prominently New Ultraman and Returning Ultraman. It wasn't until Ultraman ZOFFY: Ultra Warriors vs. the Giant Monster Army in 1984 that the then president of Tsuburaya Productions, Noboru 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. Officially, Jack is named after the hero of 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, Jack is called "Shinman" (New Ultraman - Shin Urutoraman).
===Design===
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.
==History==
===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, 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. After Jack defeated Arstron, Go applied for MAT and quickly passed their tests with flying colors. 
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. 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. 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===
After the sacrifice of Seiji Hokuto and Yuko Minami by Verokron, Jack, the Ultra Brothers, and their new member Ultraman Ace appeared to give them life, with Ace being assigned to protect Earth. 
Jack also went with the Ultra brothers to the planet Golgatha and found out that there was his name on a cross. Yapool summoned Baraba 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 Baraba. 
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 Hipporit suddenly appeared, and they were prepared to fight, but Alien Hipporit 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 of Ultra back to the land of light as he gave all his energy to Ace to save him. 
===Ultraman Story===
After taking the Father of Ultra back to M78 after the battle with Alien Hipporit and while Ultraman Taro fights Enmargo, Juda summons Grand King. The Ultras see him coming and lured him to another planet. While the Ultra Brothers were completely decimated by Grand King, Father of Ultra awakens and says Taro is the only one able to defeat it.
Mother of Ultra tells Taro this and he defeats Enmargo. He flies to the aid of his brothers. Then Mother of Ultra tells them they must channel their energy into Taro's horns. They do so and vanish, and Taro becomes a Super Ultra. He soon defeats the monster and Juda vanishes. Taro separates from the other Ultra Brothers and they return to the Ultra Star. Father of Ultra is recovered and they all have an inspirational conversation and Taro became a member of the Ultra Brothers. 
===Ultraman Taro===
Ultraman Jack, with the other Ultra Brothers, revived Kotaro after he died in a plane crash by Astromons. 
Jack and the Ultra Brothers were waiting for Taro on the Land of Light after the latter was hurt by Mururoa. 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 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 Tadao Nanbara 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 the Ultra Brothers thinking that Taro disappeared, they transform in there Ultra forms only for Taro in an Ultra Ball to destroy Alien Temperor. However, the fight wasn't over. 
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. 
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 Spacium Beam on him, but Dorobon blocked it with his weapon and defeated him in the chaos of the chase, landing on Earth. When Hideki Go 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 Leo===
Ultraman Jack went to get Ultraseven's Ultra Eye but he was stopped by Ashuran. Jack couldn't fight him with the Capsule monster, Sevenger, in hand, so he fled to Earth and gave Seven's human form Sevenger to fight Ashuran. Sevenger was winning, and was about to finish Ashuran off, when his time limit ran out of time. Later, he and Leo fought and defeated Ashuran. He took Seven's Ultra Eye and went back to the 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 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. 
===Ultraman Mebius & the Ultra Brothers===

The heroes decided the only way to defeat it and Yapool, was to seal it under the sea with the Final Cross Shield, but at the cost of not being able to transform in their Ultra selves. They used the Final Cross Shield, and the monster was sealed along with Yapool, and peace reigned on Earth for many years. Now taking on the forms of Shin Hayata, Dan Moroboshi, Hideki Go and Seiji Hokuto, the four Ultra Brothers were stranded on Earth.

After Mebius defeated Alien Zarab, he was surprisingly attacked by Alien Guts, was defeated, and sealed in a cross of crystal. Hayata, Dan and Go initially refused due to their worry of breaking the Final Cross Shield, but after a short while, they all agreed after remembering their duties as Ultramen. 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.

==Trivia==
*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, was at one point Jack's voice actor, Jack still reuses high pitched version of Ultraman's grunts produced by Masao Nakasone. The only times Jiro Dan voiced Jack in both speaking voice and grunts are in Ultraman Mebius and Mega Monster Battle Ultra Galaxy: The Movie.
*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.
