Ultraman Zero

Ultraman Zero (ウルトラマンゼロ Urutoraman 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. He is considered one of the strongest Ultras in history.

Mega Monster Battle: Ultra Galaxy Legends The Movie
A long time ago, Zero was known as a young warrior with an unlimited potential but has no awareness of his true origin. Desired for more power, he attempted to take the Plasma Spark but was stopped by Ultraseven, followed by the rest of the Ultra Brothers dragging him out of the tower.

Zero is first seen wearing the Techtor Gear armor and training with Ultraman Leo on K76, the planet he was sent to after being banished. When Pigmon was in danger, Zero decided to save it rather than continue his battle with Leo. Leo and Ultraman Kingthen revealed to him that protecting lives is the purpose of an Ultra. When Seven exiled him, he was actually saving Zero from touching the Plasma Spark and thus preventing him from a fate similar to Ultraman Belial's.

When Seven's Eye Slugger was sent as an S.O.S. 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 Beryudora, 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.

Ultra Galaxy Legend Gaiden: Ultraman Zero vs. Darklops Zero
A distortion in space brought Zero to Planet Chain where he discovered the Alien Salome's factory and learned of their invasion plot. He attempted to destroy it with help from dimensional-displaced alternate versions of the ZAP SPACY crew, but found resistance in the form of Imitation Ultra Brothers.

After a week had passed, Hiroshi Hyuga and Rei answered a distress call and their ship was drawn into the dimension containing Planet Chain. 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 dimension.

Zero attempted to escape the dimension 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 dimension and, along with Rei's Gomora, won against Mecha Gomora and Darklops Zero. Darklops Zero ended up self-destructing and destroying Planet Chain, forcing everyone to flee. Zero helped the Space Pendragon escape the dimension 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 dimension

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 Glen Fire, Mirror Knight, and Jean-bot. After the Shield of Baraji crumbled into dust, Zero was captured and his Ultra Zero Eye were 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 Deathcium Shot and ultimately lost his life from exhaustion.

Understanding the purpose of the Shield of Baraji, Nao informs everyone not to lose hope and eventually, Zero is revived Ultraman Noa, who bestows the Shield of Baraji 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 & 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 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 Saga
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 learn 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 Imago Hyper Zetton, 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 on his journey as the lights on the dark side of the planet Earth were turned back on. Ultraman Saga
