Ultraman Zero's History
Ultraman Zero is the son of Ultraseven. He was trained under Ultraman Leo after he was banished from the Land of Light by his father for attempting to take the Plasma Spark for himself. His training ultimately led to his redemption in his battle with Belial.
Long ago, Zero was a young warrior with unlimited potential and a mysterious past but lacking any sense of purpose. Seduced by the allure of power, Zero attempted to take the Plasma Spark from the Plasma Spark Tower but was stopped by Ultraseven and the Ultra Brothers. For his transgression, Zero was exiled on the K76 planet.
During his incarceration on the barren planet, Zero was subjected to regular disciplinary training under the supervision of Ultraman Leo while wearing restrictive Tector Gear. During one such training session, while sparring with Leo, Zero, in a moment of compassion, protects the life of a Pigmon who was caught between their battle. Ultraman King appears and commends Zero for his actions, explaining to him that protecting the lives of other lifeforms is the purpose of an Ultra. He elaborates that his exile was an attempt to save him, fearing had he touched the Plasma Spark, he may have suffered a similar fate as another Ultra before him, Ultraman Belial.
An S.O.S. arrives in the form of Seven's Eye Slugger lands on the K76 planet. To K76, King and Leo revealed to Zero that Seven was his father. King declared Zero redeemed and freed him from his armor, so he could join the fight against Belial. Zero arrived only to have a mortally wounded Seven die in his arms. The young Ultra was enraged and destroyed the remains of Belial's 100 Monster Army and fought against Belial himself, seemingly destroying him after a long battle.
But when Belial returned as Belyudra, it took him with help from the remaining Ultra Brothers, Leo, Astra, Ultraman Dyna, Rei, EX Gomora, and all of ZAP SPACY to destroy Belial. When the Plasma Spark was returned, Zero reunited and reconciled with his revived father again.
A distortion in space brought Zero to Planet Cheney where he discovered the Alien Salome's factory and learned of their invasion plot. He attempted to destroy it with help from universally-displaced alternate versions of the ZAP SPACY crew but found resistance in the form of Imitation Ultra Brothers (SR Team).
After a week had passed, Hyuga and Rei answered a distress call and their ship was drawn into the universe containing Planet Cheney. Zero saved the two of them from Mecha Gomora, and then encountered a robotic clone of himself called Darklops Zero. Zero fought him and ended up being banished by Darklops Zero to another reality.
Zero attempted to escape the universe but was prevented from doing so by Imitations Ultraman and Ultraseven. Leo arrived to help Zero and they destroyed the imitation Ultras with a Double Flasher. Zero exited the reality and, along with Rei's Gomora, won against Mecha Gomora and Darklops Zero. Darklops Zero ended up self-destructing and destroying Planet Cheney, forcing everyone to flee. Zero helped the Space Pendragon escape the world and flew back with Leo to the Land of Light.
After an invasion from Darklops armies, Zero volunteered himself on a mission to track their origin and his father gave him the Ultra Zero Bracelet that allowed him to transform three times in that other world.
He landed on a small quarry on Planet Anu and helped the miners defending against several Legionoids. With Run, a mine enforcer dying and Zero running out of power, he took Run's body as a host. Run had slipped into a coma, leaving Zero unexpectedly in control of his body. During his travels, he faced against armies of Belial Galactic Empire while forming alliances with other characters including Glenfire, Mirror Knight, and Jean-Bot. After the Shield of Baradhi crumbled into dust, Zero was captured and his Ultra Zero Eye was held in Belial's hands. It was then Mirror Knight leap from his tear and rescued him, regaining the Ultra Zero Eye and transformed into Ultraman Zero again but Belial's final trump card was by absorbing the collected Emeralds and transformed into the gigantic Arch Belial, easily pummeling Zero, even when reinforcements came to help. In a last effort, Zero and Mirror Knight tried to shield Planet Esmeralda from Belial's Arch Deathcium Beam and ultimately lost his life from exhaustion.
Understanding the purpose of the Shield of Baradhi, Nao informs everyone not to lose hope and eventually, Zero is revived by Ultraman Noa, who bestows the Shield of Baradhi onto Zero, transforming the Ultra into Ultimate Zero. The other giants distract Belial to provide Zero enough time to charge his attack and killed Belial for good. With his mission over, Zero left a fully healed Run and formed the "Ultimate Force Zero".
A year after Ultimate Force Zero's last battle with Kaiser Belial, the team went to rescue Emerana and Jean-Bot from a giant planet-sized sphere manned by Beatstar. Having breached an entrance, they emerged six days later to save Emerana, Rei and Hyuga before encountering Jean-Killer. After Emerana and the ZAP Spacy duo saved Jean-Bot from his brainwashing, the robot persuaded his "younger brother" Jean-Killer to join their side, which succeeded with Emerana's help. While the Ultra Brothers stopped the Beatstar Celestial Sphere from colliding Planet Bram, the team proceed to storm his tower. Zero marched further and face Beatstar before he was assisted by Jean-Killer, piloted by Hyuga himself. As the fight ended, Zero and the rest of the team accepted Jean-Killer into Ultimate Force Zero, now dubbed as Jean-Nine as they continue their missions.
After defeating the remains of Belial's army, Zero arrived on a deserted planet where he fought Zetton. Afterwards, he defeated him, but Alien Bat appeared to take Zetton for his plan and created an Anti-Ultra Field so Zero's energy would drain quicker and brought Birdon to kill Zero. However, Zoffy arrives to assist Zero and lets him borrow his Ultra Converter to regain his energy and both Ultras destroy Birdon with a combination of Zero's Zero Twin Sword and Zoffy's M87 Beam. Zoffy informed Zero about Alien Bat's plan on an alternate Earth and Zero used Ultimate Zero to get there.
Ultraman Zero heard a voice calling for help, following the voice, he traveled to another universe, finding an alternate Earth. After discovering the planet's lack of population, he then ran into Alien Bat's ship getting into a fight with his fighter drones. Taking them down one by one, one of the drones falls in the direction of a young boy and Zero witnesses the heroic act of Nozomu Taiga, who sacrificed his life to save the child, even though Zero saved the boy first. Zero was moved by his act and decided to merge with him and make him his human host, but Taiga was annoyed that he had to share his life with an Ultra and refused to transform, due to a grudge against the Ultras for the death of his parents during an alien attack on Earth where Ultraman Dyna failed to protect them.
After their encounter with Musashi and Team U, the two were led to learning how Alien Bat had kidnapped almost an entirety of the population to empower his Hyper Zetton. During Gubila and Gomess (S)'s attack, Taiga's refusal to cooperate and Zero's forced transformation rendered the giant 5 meters short. Although Zero managed to get Cosmos to tame them, Bat killed the monsters for their failure and sent Hyper Zetton to attack the Team U base the next day. It was during this time where the two finally put aside their differences and Taiga managed to transform into Zero. Alongside Cosmos, the two stormed Zetton's nest, allowing Takeru and Anna to restore Asuka/Dyna at the expense of her own life. The three Ultras combined their powers for Ultimate Zero to deliver the final blow, but Alien Bat fuses his ship with his Hyper Zetton to form Hyper Zetton (Imago), successfully overpowering the Ultras and killing Zero. As the three Ultra Hosts stood up again, their bravery allows them to fuse their Ultras into Ultraman Saga, therefore killing both the monster and alien for good while restoring the kidnapped populations. Dyna and Cosmos returned to their universes while Taiga stayed. Zero waved goodbye to his new comrade and continued his journey as the lights on the dark side of the planet Earth were turned back on.
While journeying in the Monster Graveyard, Zero faced himself against a quartet of revived monsters. The mastermind appears as Alien Bat, who unveils his monsters as the four beasts of hell. In against EX Red King, he was forced in a one-sided battle but escaped from it via Strong-Corona and defeated the monster when it tried to attack a helpless Pigmon. Suddenly Zero found himself in a white space at the same size as Pigmon and Alien Bat. Facing phantom copies of his Mode Changes, Zero finally countered their surprise attack, therefore killing the true enemy Galberos. Soon he went against Gan-Q and Bemstar, simultaneously kill them by exploiting their new powers.
It was then that Alien Bat made his move and absorbed the Four Beast of Hell as his antibodies, fighting the Ultra in his giant size while gaining the knowledge Zero's movements. Bat as well revealed that his life is linked to Pigmon, forcing Zero on the mercy of the alien until he heard Pigmon's cries and understood what the little creature was trying to tell him. Before Bat could slice the Ultra with his sword, Zero split into his Mode Changes, using Luna-Miracle to expel the deceased monsters' spirit from Bat and save Pigmon while Strong-Corona delivers the finishing blow. Reuniting with Ultimate Force Zero, the Ultra finally knew the purpose of his new power as they left.
After dealing with King Silvergon's attack on Fanegon People's planet, Zero was told by Mother of Ultra that trouble had befallen his team, and in the Mighty Base, they found that Mirror Knight and Glenfire had been turned into bronze.
Fortunately Zero had sensed something was wrong and exposes "Mother of Ultra" to be Jatar, killing the alien before his full petrifaction and rescue his victims. After being cornered by Villainous, Tyrant, Grocken, and Deathlogue, the young Ultra's comrades appear and kept the aliens occupied, leaving Zero to save Pigmon from Mefilas Sly. Beaten but not destroyed, Sly unveiled Belial as the Darkness Five's leader, resurrected from death by possessing Armored Darkness. The entire fight which leads to Zero's victory turned into a trap that allows Belial to possess Zero as Ultraman Zero Darkness while using his own powers to slay the Ultimate Force Zero.
The young Ultra could only watch in helplessness and falls into despair but moments before Belial could kill Pigmon, Zero stopped him and transformed into Shining Ultraman Zero. With his new power, the Ultra expelled Belial and turn back time in the local area. The other members of the Ultimate Force Zero were revived, and they all headed back to the base with Pigmon, their new team member.
Ultraman Zero participated in the Dark Spark War but this time he fought not only alongside with his father and the Ultra Brothers but, with other Ultras from other universes and their allies against the forces of evil. While in the midst of the battle, Dark Lugiel appeared and turned every Ultra alongside their allies, monsters and aliens into Spark Dolls. Just as the war was about to end, an unknown warrior appeared and faced Dark Lugiel, but like the others, he was also turned into a Spark Doll. However, he was kept within his Ginga Spark and fell alongside other Spark Dolls to Earth. After Ginga defeated Lugiel, all of the Ultras and Kaiju returned to normal and went back home.
After Cosmos' defeat at the hands of Etelgar at Planet Juran, Ultraman Zero pursued him but Etelgar escaped and left with the excuse that Zero would be his main dish (last target). He chased Etelgar to Earth, but after meeting Ginga and Victory, Zero called them to pass a trial so they would be able to use the Ultra Fusion Brace which was given to him from Ultraman King. He later helped Ultraman Gingavictory and the Heisei Ultras against Etelgar, but like most of them, he was forced to fight an Eteldummy of his nemesis: Ultraman Belial.
Zero was hunting Alien Nackle Bandello in space after the alien was reported for being a thief and an arms dealer. He tracked Bandello to Earth and faced him when Ultraman X battled both alien and Black King. After he managed to sever Black King's horn, Zero tried to chase Bandello by attacking him but X stopped him since Bandello also brought a human escort.
Using Rui's SOS message, Zero managed to find her at Planet Guillermo and attacked Bandello and Black King Drill Custom. X arrived late with Ultraman Zero Armor, a copy of his Ultimate Aegis and the two defeated both alien-monster pair. Zero departed and wishes to meet X again in the future.
Sent by the Inter Galactic Defense Force to investigate a strange energy on Planet Yomi, Zero encountered Juda Spectre and Mecha Gomora before Ultraman Orb helped him in defeating both villains. Not long after, the two were visited by the mastermind Reibatos, who revived six monsters before leaving. Having at least destroyed two of them, Zero had Orb tail the villain before Jack, Seven and Zoffy came to his aid and alongside his father, trained Orb in an isolation for 10 years. With Orb obtaining Emerium Slugger, Zero and his father aided the former in fighting Tyrant and left him to fight Reibatos. At the end of the battle, the Inter Galactic Defense Force offered him a position in their rank, to which he politely declined. After Orb as Gai left, Zero remembers the Giga Battle Nizer's disappearance but kept the issue silent.
During the Omega Armageddon, Zero and the rest of the Inter Galactic Defense Force faced against Belial and his army on Earth but was defeated. As the Crisis Impact took place, his determination was held back by his father before King merged himself with the universe, preventing it from collapsing.
Six years had passed and the theft of Ultra Capsules forced Zero in an investigation back to Earth with the last power of Ultimate Bracelet before it wrecked.
Upon arrival, an injured Zero was forced to recuperate with a salaryman Leito Igaguri while meeting Ultraman Geed, having well aware of the young boy's relationship as Belial's son and at the same time mentoring him. After trading his life for the hostages held by Kei Fukuide, Zero was revived from Leito's own will and receive a set of Ultra Capsules by Ultraman Hikari, providing access to Ultraman Zero Beyond. Initially believed to have sealed Belial in his own dimensional tear, the fiend managed to escape and descended to Earth. Zero try to settle it with his own hands but later on left his former enemy to Geed, who did so via Royal Megamaster and complimenting the young Ultra in the aftermath.
With Kei Fukuide still at large, Zero continued to aid and assist both Geed and the AIB forces. When Belial returned as Atrocious, Zero participated in the operation to distract him as RE.M. delivers the enzyme neutralizer to his Color Timer. With the operation failed, Geed's intervention was enough for Zero to deliver the object personally at the expense of his health. Geed's determination and courage was later sensed by Zero in defeating Belial. In aftermath of the battle, Zero bid farewell to his host and departed with the newly fixed Ultimate Bracelet.
Zero first appears fighting a group of Galactrons, alongside the Ultimate Force Zero. When the group was informed by Zoffy that Gillvalis had targeted Geed's Earth as the next planet to judge and reset, they arrived at the World of Side Space to stop the threat. While Ultimate Force Zero could only guard the Ultras in space, Zero arrived in the nick of time and joined forces with Ultraman Geed and Ultraman Orb, and engaged in a tough battle with Galactron MK2. After Orb saved Geed from the cyberspace he was sent to, Zero and Orb were seemingly killed after Galactron unleashed a series of energy missiles. However, Zero quickly used the Shining Star Drive to survive the assault.
Bonding with Leito Igaguri once again, Zero destroyed the remaining Galactrons on Earth and arrive at Cyber Planet Kushia alongside Geed and Orb, fighting against Gillvalis in his Perfect Form. The Ultras finally ended the artificial intelligence's reign with Geed delivering the final blow. After the battle, Zero alongside the Ultimate Force Zero left the Earth after entrusting it to the hands of Riku/Geed.
Ultra Dark-Killer was targeting Ultrawoman Grigio on Earth, who had been left there to protect Ayaka City while her brothers were studying overseas. Zero was sent by the Inter Galactic Defense Force to protect her but encountered Dark-Killer along the way. Dark-Killer suddenly arrives through a portal chasing Ultraman Zero to Ayaka City, where Grigio was training. He demanded Zero to hand her over, but he refuses, so Dark-Killer sends them both to his Dark-Killer Zone. Even though he and Grigio had their energy slowly drained away, Zero still donated his energy to Grigio without her knowing to keep her alive.
While Rosso and Blu fought against Ultra Dark-Killer, he created Ultraman Zero Darkness from the ambient energy in the Dark-Killer Zone, based on Zero's trauma of being possessed by Belial. Zero had to fight against his Darkness copy, which had been previously defeated by Ultraman Ruebe, after it was revived by Ultraman Tregear. To assist him, Geed, Orb, X, Victory and Ginga put their powers together to transform Zero into Zero Beyond (Galaxy Glitter), since he is unable to do it himself without Leito. With that, Zero proceeded to eliminate Zero Darkness via the Twin Giga Break. Following the destruction of Dark-Killer, Zero transported back Grigio to her home universe to protect Ayaka City while her brothers joined the New Generation Heroes to pursuit Tregear, who intended to destroy both Taro and the Land of Light.
After the Six Ultra Brothers defeated Juda and Mold, they were soon faced by parallel isotopes of Ultraman Belial and Ultraman Tregear who had appeared via Absolute Tartarus altering the timeline. As the two were about to finish off the Brothers, Zero arrived to stop them, surprised to see his arch enemy in his young appearance. Despite his best efforts, Zero was no match for the two Ultras, who had been enhanced thanks to Tartarus enhancing their abilities. Tartarus himself soon showed up and easily overpowered Zero, who was helped back up by the Ultra Brothers, as the trio of villains entered the golden portal behind them.
Later at the Inter Galactic Defense Force Headquarters, Zero was assigned by Father of Ultra to assemble a team to combat Tartarus, since he is able to travel between dimensions. The Divergence Zero first went to Ayaka City, where he recruited Ultrawoman Grigio to help him deal with Tartarus while her brothers were out dealing with the Devil Splinters and also visited U40 to recruit Ultraman Joneus for his mission after the latter briefly confronted Tartarus.
When the Artificial Zetton Army attacked 80 and Yullian, causing them to crash on Planet Ebil, Zero and the Ultra League arrived to assist Mebius, Taiga, and Z with the rescue efforts, with Zero teaming up with Taiga. When Absolute Tartarus attempted to take advantage of the confusion to capture Yullian, Zero countered by combining his Ultimate and Shining forms to form Ultimate Shining Ultraman Zero. Freeing Yullian, Zero declared he was getting bored by all the small fry, and he was ready to finish things. Zero and Tartarus entered the portal to Narak, where they fought. However, his new form was poorly optimized, and consumed too much energy. As a result, Zero quickly grew weak during the fight, and was defeated by Tartarus.
Soon after defeating Ultimate Shining Zero in Narak, Absolute Tartarus appeared, taking Yullian hostage and informing the heroes of his true motives before getting Ultraman Belial and Ultraman Tregear to fire their beams at them all. The group also received word from Ultraman Hikari that Genegarg had stolen a Z Riser and Ultra Medals from the Land of Light, causing Z to fly off in a hurry while Zero followed him. The Ultra League and the Tri-Squad prepare to recruit more heroes for the upcoming fight against The Kingdom.
Meeting Ultraman Joneus in the Ultra Colosseum, Zero requested that he trained him, noting how Joneus was the only one to be Absolute Tartarus' match so far, and that he had yet to attain full control over the power of Ultimate Shining. Returning to Planet K76, Zero and Joneus were joined by Ultraseven and Ultraman Leo to help Zero with his training, with Seven using his Ultra Psychokinesis to bind his son in a set of Tector Gear. Seven, Leo and Joneus spar with Zero and advise him that the only way that he could stand a chance against Tartarus was to fight by using his instincts, which he could only accomplish if Zero managed to regain the wilder side he had earlier in his youth, despite the encounters he had making him stronger up to that point. Looking into himself, Zero managed to unleash his primal instincts, changing into an all red form of himself. Just then, Astra arrived to inform the Ultras present that Tartarus had been spotted on Planet Babel, and was fighting Ultraman Ribut and the Ultra Force.
The five of them quickly rushed to Planet Babel and fought against Tartarus and his minions, later being joined by Ultraman Nexus and Seven's Capsule Kaiju - Agira, Miclas and Windom - when he summoned them. Zero used his new abilities and changed into Ultimate Shining once more to challenge Tartarus, who was caught by surprise. With Leo and Astra's help, the three of them drive Tartarus away. Zero then continued to train with Astra, seeing the Cosmo Beast Fist for the first time when Astra imitated someone who he used to spar with.
After the rescue squad managed to escape from the Kingdom with Yullian and Ultraman Regulos, they arrived on Planet Blizzard pursued by the Absolutians and their forces, only for them to be met with a large gathering of Ultras. Zero and Seven took on Tartarus, until the latter joined Mebius and the Ultra Brothers to fuse into Mebius Infinity to close the Absolutian portal to halt their reinforcements while Zero continued to fight Tartarus. At the climax of the battle, Tartarus was overwhelmed by Zero with his new abilities. He decided to unleash his Absolute Maximum Destruction on the planet, but it was blocked by a barrier from Ultraman King, creating a wormhole from the impact. Ultraman Ribut created his own barrier to protect the other Ultras present, but he and Tartarus fell through the wormhole and into Ultraman Trigger's universe as a result.
Some time passed in peace and Zero continued to train with Regulos, in order to prepare for the coming of the Absolutians and their 'lord'.
