Ultraman Max's History
Ultraman Max is the titular giant of his series. He was a Civilization Guardian sent from Nebula M78, and bonded with Kaito Touma to defend Earth from monsters and alien attacks.
A Civilization Guardian, Ultraman Max's job was to study developing civilizations and help devise a way for the various species of the universe to co-exist. His later mission was the planet Earth which was facing a crisis brought about by man's folly. However, it was stated that Max's first arrival on said planet dated way back in the distant past.
Max observed Earth and witnessed the bravery of a native youth named Kaito Touma. Rather than leaving him to a cruel fate, Max merged with him and allowed them both to protect the people of Earth. After saving Kaito, Max began to fight monsters from Earth's past and invaders from space that wanted the destruction of either humans to have the planet for themselves, with DASH fighting alongside him.
During his battle against Zetton, Max was being severely beaten by the legendary monster and would have died if not for the appearance of Ultraman Xenon, a fellow member of the Inter Galactic Defense Force. During that battle, Max gained the Max Galaxy, a multi-purpose device that saved Max many times afterward and be used to destroy his old enemy Gilfas.
Months later after stopping numerous monsters and invaders, the Delos People rose up to threaten the surface people of Earth. Max could not interfere because it was against the laws of his home world of the Land of Light to interfere with wars between native civilizations. However, Kaito stopped any such conflict, while also saving Mizuki from a near-death experience, by making Delos change his mind and call off the war, they both agreed that neither side had actually wished for a conflict.
The people of Delos requested Max to stop their now rogue defense system, allowing Max to attack their superweapon Giga Berserke. However, between rising to the surface and flying to battle, Max had little time to fight. Max lost to Giga Berserke and turned to stone after separating Kaito from his body. Unwilling to surrender, DASH revived the hero by recharging the Max Galaxy, which Kaito merged with and flew to Max to again merge with him one last time. After a short assault, Max destroyed Giga Berserke and left Earth with Xenon to return back home to Nebula M78.
After Ultraman Belial was freed, he returned to the Land of Light. Upon arriving, he showed that Ultraman Taro was defeated by him. After the Ultramen witnessed this, all of the Inter Galactic Defense Force's warriors charged at Belial. Max was the first one to attack but was defeated by Belial after receiving a few hits from the Giga Battle Nizer. Even after all the long battle, they were all defeated by Belial, and who then took the Plasma Spark, all the Land of Light was frozen, along with every Ultra. After Ultraman Zero defeated Belial and returned the Plasma Spark, all of the planet's people were revived. Shortly afterward every Ultra went to listen to Ultraman King's speech.
Ultraman Max and Ultraman Ribut were deployed to Planet Mikarito to investigate the planet's unusually accelerated aging. While exploring the planet's caverns, the two Ultras came across the egg of a Maga-Orochi, which Max deduced to be the source of the damage to the planet. Suddenly, a Hellberus appeared, and the two Ultras teamed up against the monster, holding the upper hand, until Alien Sran arrived and ambushed the duo. After overpowering both Ultras, Sran infected Max with Gudis Cells, severely weakening the Ultra and allowing the Maga-Orochi egg to grab hold of Max and begin draining his energy. As Sran gloated that Max would soon turn into an 'ugly monster' and become Maga-Orochi's source for the energy it needed to hatch, Max urged Ribut to escape and report back to the Inter Galactic Defense Force with information about what happened, before falling unconscious. After arriving on the Land of Light, Ribut informed Zoffy, Taro and Hikari about what he had seen. Through analysis of Max's condition, Hikari realized that though Max was attempting to focus his Inner Light to fight the Gudis Cell infection, at the rate the cells were infecting his body, he would succumb to the infection within three days. Hikari and fellow scientist Sora, Ribut's childhood friend, set off to begin developing artificial antibodies to treat Max's infection, while Taro instructed Ribut to journey to Planet K76, a planet often used as a training ground, so that he could become strong enough to help rescue Max in an expedition to Mikarito that was planned to take place three days later.
On the day of the expedition, the infection had progressed to the point that one of Max's arms had become mutated by the cells, and he had become brainwashed by the effects of his sickness. When Ultraman Ribut, Great and Powered arrived at Mikarito, the Maga-Orochi egg released Max to fight the three Ultras. While Great and Powered dealt with Alien Sran and Hellberus respectively, Ribut managed to isolate the Gudis cells from Max after injecting him with the Gudis Vaccine.
Though Max was seriously weakened by his ordeal, he was still prepared to fight Maga-Orochi, though the odds of victory seemed slim. However, just in the nick of time, Max was given the Max Galaxy, which recharged his energy, and Xenon arrived! The three Ultras then proceeded to tag-team and defeat Maga-Orochi, whose powers had been enhanced by the Gudis cells. Max returned to the Land of Light afterward, where Zoffy discussed about the presence of Absolute Tartarus.
Ultraman Max was seen to have participated in the Dark Spark War. But in the middle of the battle, a powerful villain known as Dark Lugiel, using the power of the Dark Spark to transformed all Ultras, aliens, and monsters into Spark Dolls. It fell to Earth with the other Spark Dolls. The location of Max's doll is unknown but nonetheless after Dark Lugiel's defeat by Ultraman Ginga, Max was restored to his original appearance and with other victims of Dark Lugiel, return to their homes.
Ultraman Max was captured along with the Heisei Ultras by Arena and Etelgar. He would later fight together with Nexus, Mebius, Zero, Cosmos, and Ginga Victory in Etelgar's Space-time Castle. After Nexus left behind to fight the Dark Mephisto's Eteldummy on the first floor, the group met another resistance on the second floor in the form of Alien Sran, Max's old enemy. As Max faces his old foe, his comrades race upstairs to the third floor.
After knowing that an Alien Sran named Quila wanted revenge on him for killing one of his brethren, Max went to an alternate Earth, taking the form of Kaito and exposed Quila as the villain he was to Xio, the attack team of that world. However, the Ultraman of the world, Ultraman X, was battling with Quila's Zetton at this time, and X fell into Quila's trap, his consciousness slowly being overtaken by the Zetton Armor that Quila had tricked X to wear. Max transformed back to his Ultra form to save a mother and daughter from a failing building, then joined the fight to help X. However he was eventually outnumbered by Zetton, a controlled X and even Quila. Eventually, Daichi Oozora managed to rid the Zetton Armor's malicious programming, and X regained consciousness and protected Max. Max finished off Quila with Galaxy Cannon while X destroyed Zetton. Meeting Daichi and X in the form of Kaito, Max gifted them a portion of his power in a form of a Type U Cyber Card and then returned to his own universe.
