Ultraman Zero

1="Who are you?!" "Zero! Ultraman Zero! Son of Seven!"

- Belial and Zero, Mega Monster Battle: Ultra Galaxy Legend The Movie

2="I am Zero, Ultraman Zero"

- Ultraman Zero's catchphrase

Ultraman Zero (ウルトラマンゼロ) 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
"Dan: We can't see him until he's done training. Rei: Why? Hayata: Once, he too went after the Plasma Spark energy. Mirai: He was young; immature. Tempted by the power. He almost lost his soul to evil. Just like Belial. Dan: It was the hardest thing we had to do. Mirai: He was too young to realise the danger of power without justice."

- Zero's past described from the Ultra Brothers' point of view.

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 King then 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 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 dimensionally 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.

Ultraman Zero The Movie: Super Deciding Fight! The Belial Galactic Empire
When the Land of Light was invaded by Delusts battleships, Zero was among the resistance and effortlessly killed them, until the real trouble appears in the form of mass-produced Darklops. With the help from his father, Seven, they managed to cleanse the army. A part from the Darklops was salvaged in a meeting of the Space Garrisons, where they deduced that its technology was created from somewhere in the other world. Zero accepted the offer to venture on the source, and his father gave him the Ultra Zero Bracelet that allowed him to transform three times in that other dimension.

Thanks to his fellow Land of Light residents, he arrived in the dimension which believed to be the source of the Darklops. He landed on a small quarry on a planet, 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 became allies with several characters including Glen Fire, Mirror Knight, and Jean-bot. Zero also battled against the army of the revived Galactic Emperor, Kaiser Belial. But as it seemed that he and his group reached the Shield of Baraji, it crumbled to dust.

In the end, Zero was captured and his Ultra Zero Eye were held in Belial's hands. It was then Mirror Knight leapt from his tear and rescued him, regaining the Ultra 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 the others from Belial's Deathcium Shot and ultimately lost his life from exhaustion.

Not intent on losing and now understanding the purpose of the Shield of Baraji, Nao informs everyone not to lose hope and eventually, Zero is revived and brought forth by Ultraman Noa, who bestows the Shield of Baraji onto Zero, transforming the Ultra into Ultimate Zero. The other giants distract Belial to give Zero some time to charge seal him, thus liberating invaded planets from Belial's forces. With the defeat of Belial, Zero left with Run fully revived. Zero formed a new alliance, calling it the "Ultimate Force Zero".

Ultraman Zero Side Story: Killer the Beatstar
A year after Ultimate Force Zero's last battle with Kaiser Belial, the team encountered a giant planet-sized sphere manned by Beatstar, which kidnapped Jean-bot and Emerana. The remaining three Ultimate Force Zero, Ultraman Zero, Mirror Knight and Glenfire broke into the sphere and fought it. They emerged six days later via Mirror Knight's reflection ability and saved 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. With the Ultra Brothers stopped the Beatstar Celestial Sphere from colliding Planet Bram, the team proceed to storm his tower. Leaving his comrades with the rest of the army, Zero marched further and face Beatstar before he was assisted by Jean-killer, piloted by Hyuga himself. Before his death Beatstar admitted that he just fear that living-life form will turn evil like his creators.

After everything is over Jean-killer had been renamed by Emerana as "Jean-nine" and Zero had him joined the team as well. After Ultraman, Ultraseven and Zoffy left to Land of Light, Ultimate Force Zero is ready to save the Universe again.

Ultraman Saga Special DVD
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 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 lead to how Alien Bat had kidnapped almost an entirety of populations 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 meter 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 storm Zetton's nest, allowing Takeru and Anna to restore Asuka/Dyna at the expense of her own life. The three Ultras combine 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 Host 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.

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 finisher blow. Reuniting with Ultimate Force Zero, the Ultra finally know 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 Glen Fire had been turned into bronze.

Fortunately Zero had sensed something was wrong and expose "Mother of Ultra" to be Alien Hipporito. The evil alien noted how Zero's hand was turned to bronze and boasted before Zero used the same hand and Strong-Corona mode to beat him senseless, knocking him out of base and into an asteroid before finishing him of with the Garnate Buster. With the alien destroyed, Zero's hand turned back to normal but before he could go check on his friends he was set upon by an Alien Temperor and Tyrant. To make things worse, Alien Groza and Alien Deathre join Temperor in a competition to defeat Zero before the young Ultra's comrades appear and kept the aliens occupied, leaving Zero to save Pigmon from Mefilas Surai. Beaten but not destroyed Surai announced the entrance to the power behind the Darkness Five. As lightning struck the top of a nearby mountain Zero and Pigmon spied the form of Armored Darkness, who was revealed to be Belial, who was resurrected from death by possessing said armor. After fighting in a heated battle, Belial possess Zero into Zero Darkness and slayed his comrades with Zero's own powers.

Body Features

 * Protector (プロテクター): Like his Father, Zero has Protectors on his chest, back and shoulders, which act as both armor and solar panels.

Transformation
Zero's host can use the Ultra Zero Eye to transform into Ultraman Zero. It is generally first summoned from the Ultra Zero Bracelet that appears on Zero's host and his Ultra form. Upon use the rise scene is similar to his father, except a full body shot of his host is seen as light particles gathering to transform him into Zero followed by his Zero Sluggers and appearing and resting on his head.

He also has a "rise" sequence in Shining form, but it was only used to free himself from Belial's dark power. Thus, its status as a rise sequence is debatable.

Quotes

 * "Zero! Ultraman Zero! Son of Seven!" (Zero speaking to Ultraman Belial)
 * "You'll pay for this." (Zero speaking to Belial again when he see his home being attacked)
 * "We still have our bright future!" (Zero's famous quote in Ultraman Saga)
 * "Not yet. I...haven't given up yet! There are those I must protect! I am...an Ultraman!" (Zero's words just before first transforming into Shining Zero)
 * "Do you have them? Those you protect. Why do you only take lives, and never protect them? Aren't you an Ultraman?!" (Shining Zero's speech before forcing Ultraman Belial out of his body)
 * "I am the real Ultraman Zero!" (Shining Zero speaking to Ultraman Belial)

Trivia

 * Ultraman Zero was originally going to be called by the initial draft name UltraSeven AX (ウルトラセブンアックス) by Masayuki Gotou and would've resembled an all red version of his current appearance, possibly minus his Color Timer. His Zero Sluggers were originally called the Double I Sluggers and he had several different powers from what his base form currently has, such as a flame covered dash and turning the Double I Sluggers into a bow. However, this decision was cancelled, he was renamed Ultraman Zero and his body was added the blue as well.
 * These changes were most likely made to make him feel more like an original Ultra, as opposed to another revamped version of Ultraseven.
 * Due to how common the red color is among Ultra Warriors, blue was added as well to make him more attractive to new viewers.
 * His Techtor Gear Zero was meant to be called Armored Ax (アーマードアックス Āmādo Akkusu). Because of the difficulty in designing Zero, Techtor Gear Zero was made first to hide his original appearance. It was initially planned to have a sharp design but producer Junya Okabe proposed a daring appearance. Its suit is a separate molding from the original Zero while the orange tubes were portrayed to be able to expand and contracting itself.
 * The Zero Twin Sword, the combined form of his Zero Sluggers, was meant to be a bow and arrow configuration during the time he was called UltraSeven AX, although the design was later incorporated into the Ultimate Zero form.
 * Yuji Kobayashi revealed that the reason he named the character as "Zero" is to symbolize the "restart of Ultraman story from scratch".
 * Ultraman Zero is the first known Ultra from the Land of Light who is naturally both blue and red colored.
 * In March 2011, an official Twitter account of Ultraman Zero told the readers to be careful of "strangers" that offered them the chance to become a "magical girl". The post itself is a joke to a popular anime series, Puella Magi Madoka Magica which featured the main antagonist Kyubey manipulating girls (including the main characters of that series) into a magical girl and had become viral in the Japanese fandom ever since, creating a strings of internet meme that featured Zero facing Kyubey. Interesting enough on that same month and year, a civilian caught a photo of Ultraman Zero choking Kyubey's rag doll, further boosting up the meme.
 * In Ultraman Saga, Ultraman Zero's rise is a combined sound of the Leo Ring and Ultra Eye.
 * Zero is the third Hesei Ultra who has fused with another Ultra (Dyna and Cosmos, thus forming become Ultraman Saga).
 * Ultraman Zero is the first Ultra who had human hosts before took a human form.
 * However, he is not the first Ultra to use both human hosts and a human form. That honor actually goes to his father, who first assumed a human form before he took on a human host (excluding Masaki Kazimori Ultraseven's human host from the Heisei Ultra Seven timeline).
 * Ultraman Zero is the second Ultraman to have a mid-transformation that was not the Ultra's full size. Zero breaks the record at being only 5 meters. The first was Ultraman the Next, who was 10 meters in his mid transformation.
 * Ultraman Zero is the first documented Ultra to have met different Ultras from other universes.
 * Shining Form first appeared in Zero's mind before it was materialized in his real body.
 * Currently, Shining form is the only form that Zero achieved by himself. Since, Ultimate Form was a gift from Ultraman Noa, StrongCorona mode and LunaMiracle mode were gained due the fusion that created Ultraman Saga while Zero Darkness is a forced transformation when possessed by Belial. However Shining form is a combination of all these powers (Minus Darkness obviously) within his body due him fully merging with the Ultimate Brace and the Shield of Baraji within it, meaning the potential for this form was always there since he received the Ultimate Brace and the other forms.
 * Susumu Kurobe, the actor of Shin Hayata and the current voice of Ultraman states that Zero is his favorite Ultra Warrior, while his favorite Ultra Kaiju are Pigmon and Woo.
 * Zero had the tendency to relate things to 20,000 years in his speech while performing a backward peace trademark. This is likely a reference to the original Ultraman, whose age at the time of his first arrival on Earth and his first departure is 20,000 years.
 * This as well may be a reference to one of Tieria Erde's famous quotes "You deserve ten thousand deaths!" from episode 19 of Mobile Suit Gundam 00.
 * Ultraman Zero is the starting trend for most Heisei Ultramen and Tsuburaya Heroes to be voiced by Mobile Weapon pilot voice actors of the Gundam franchise.
 * Zero's design and appearance is literally a joke to the main character of Mobile Suit Gundam 00, Setsuna F. Seiei and his Mobile Weapon GN-0000 00 Gundam. As shown:
 * Both Ultra and Mobile Weapon were named after the digit number "Zero" and had the same color-scheme. Also noted that they even acquired armaments (0 Raiser and Ultimate Aegis) which seemingly allowed them to achieve their strongest forms. Another coincidence is that they are empowered by solar energies and the first to use these concepts (Gundam 00 utilizes two GN Drive (Twin Drive System) and Zero uses two Crest Weapons, Zero Slugger).
 * Both Ultra and pilot had a well known catchphrase to introduce themselves, "I am Gundam/Zero!" (俺がガンダム/ゼロ). They even share the same voice actor, Mamoru Miyano. Interesting to note that in their final form/appearance, their skin color turns completely silver, with Zero using Shining Zero and Setsuna's reason is probably him having assimilated to the ELS.
 * Ironically, Luna-Miracle Zero's Miracle Zero Slugger attack is similar to how Chaosroid S attacked with its Eye Slugger in Ultraman Fighting Evolution Rebirth.
 * The Shining Field erected by Shining Ultraman Zero is based on the Hyperbolic Time Chamber from the Dragonball franchise, both of which are dimensions with a faster time flow that allow its users to train themselves in a short time.
