Alien Bat's History
Alien Batare an alien race that debuted in Return of Ultraman. The first Alien Bat was aiming to conquer both Earth and the Land of Light, and a second one appeared in the Future Earth World, controlling Hyper Zetton. Since then, numerous Alien Bat bearing a resemblance to the second have appeared over the course of the remainder of the Heisei era and recent Reiwa era instalments of the Ultraman Series.
Alien Bat had createdterror across the universe and was indirectly responsible for the creation of Beatstar, whose creators used to navigate their Beatstar Celestial Sphere, a planetary vessel made from various planets slew by Alien Bat's conquest.
The Alien Bat arrived on Future Earth to start his experimentation with Zetton. Bat carried out his mass abduction of Earth life forms, first by kidnapping the animals and eventually expanding to the human population. The few humans that remained included several children and a team that would declare themselves as Team U. For a year, Alien Bat had been tormenting their lives with multiple monster attacks (including an Arstron) that required Shin Asuka as Dyna to interfere, but Bat managed to petrify him using Hyper Zetton's coccoon.
Using his spaceship, Alien Bat would travel into the World of Neo Frontier Space to kidnap remnants of Spheres as Hyper Zetton's rations, inadvertently bringing along Nozomu Taiga to the Future Earth and setting his bond with Ultraman Zero.
With Musashi/Cosmos further complicating his plans, the alien decided to send a Gubila and Gomess (S) to attack the refugee area, eliminating them after Cosmos managed to pacify the monsters. When Taiga and Musashi decided to unleash their assault against Alien Bat's Gigant Hyper Zetton, Dyna was revived through Anna's help and the Zetton was killed by Ultimate Aegis. Alien Bat combined his saucer with Hyper Zetton to evolve it into Imago, declaring himself worthy of a god and used his monster to fight against the Ultras. The spirit of the Ultras' hosts combine them into Ultraman Saga as an opponent worthy of Bat's Hyper Zetton.
In the director's cut version of the film, Alien Bat, within Hyper Zetton, unleashed five Monster Weapons (怪獣兵器, Kaijū Heiki) he made through monster corpses reanimated by the Sphere's powers. The monsters in question were Antlar, King Pandon, Black King, Verokron, and Tyrant. As Ultraman Saga continued his fight, the Ultra Brothers appear to aid the Super Ultra in battle, keeping the Monster Weapons away from the battle while they dealt with each of them.
After a battle across the city, Saga delivered his finishing blow to the Hyper Zetton in outer space, simultaneously punching Alien Bat from the position where he controlled his creation. The death of Hyper Zetton caused all of the kidnapped life forms returned to Earth.
In the miniseries, Ultra Zero Fight, another Alien Bat, who was a relative to the one from Ultraman Saga, appeared. This Alien Bat was named Gurashie.
Gurashie traveled to the Monster Graveyard and revived Telesdon, Gudon, Sadola, and Bemular. Ultraman Zero easily defeated the first wave, thanks to his recently acquired ability to change forms. Alien Bat Gurashie then unleashed four more powerful monsters: Red King, Gan-Q, Galberos and Bemstar, whom will be given the title "The Four Beast Warriors of Hell". When Zero jumped to clash with the monsters, Bat shot a beam that trapped Zero in a Tector Gear made from the restless souls of the monsters he defeated, severely hampering his fighting ability. Gurashie made his Red King evolve into its EX form, who beat Zero with its powerful arms. Zero tried to gather himself, but Gurashie triggered the Tector Gear into electrocuting Zero, and EX Red King knocked him unconscious. Later, Zero was able to defeat EX Red King, but was sent into a dimension where he was forced to fight himself by Galberos.
After that, Zero defeated Gan-Q and Bemstar. However, the souls of the four dead monsters would be absorbed by Gurashie in order to allow him to transform into his giant sized form. Although the battle began in the Ultra's favor, Gurashie had managed to overpower Ultraman Zero by revealing his friend Pigmon was part of his experiments to revive dead monsters. If Gurashie died, so to would Pigmon. Unable to focus, Zero was at the alien's nonexistent mercy but survived when he managed to split apart into Strong-Corona and Luna-Miracle forms and manage to turn the tables. Luna-Miracle Zero then use a purifying technique to free the trapped monster spirits inside Gurashie, the then purified souls left Gurashie's body peacefully. With the loss of his power Gurashie became infuriated which gave Strong-Corona Zero the chance to grab him and use the Ultra Hurricane to throw him into the air where the same technique held him in place as Strong-Corona finished of Gurashie with the Gulnate Buster as Luna-Miracle Zero saved Pigmon from being destroyed with Alien Bat.
Gurashie's actions and defeat were observed by the Darkness Five, who stated Gurashie had served them well in learning Zero's strengths and weaknesses, which they could use to their advantage in Kaiser Darkness' plan.
