"Do you think you have won? What you have defeated was only Zetton's larva! This beautiful form! This is... This is... This is its complete form, Hyper Zetton! I have finally become the god who will bring death to all worlds!"

―Alien Bat, Ultraman Saga.

This Alien Bat (バット星人 Batto Seijin) is an elite member of his race who served as the main antagonist of Ultraman Saga.

Alien Bat, as seen in the side story

Alien Bat had created multiple terrorism 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.[1] Ultraman Zero Gaiden: Killer the Beatstar

Pre-Ultraman Saga

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.

Ultraman Saga

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. Ultraman Saga

"Who are you guys? I'm looking for Ultraman Saga-"
"You died once, and now you've come back to life. Won't you pledge your life to The Kingdom?"
"A-All right. I've got a plan I've been meaning to try. F-free me and I'll cooperate.

―Alien Bat and Tartarus.

While Absolute Tartarus was traveling elsewhere when Alien Sran's scheme took place, he visited the Moon of Future Earth and had Reibatos revive Alien Bat from his death. The Beginning Surprised by his sudden revival, the alien accepted Tartarus' offer to pledge his loyalty to The Kingdom and went to his lab to create the Space Fear-Demon Zett as their tool against the Ultras.

Absolute Tartarus had brought Bat and Reibatos to the Monster Graveyard, where Gina Spectre had just recovered a Devil Splinter from Ultrawoman Grigio, Ultraman Zearth, Ultraman Nice and Ultraman Boy. Bat had recreated the Killer Plasma that Ultra Dark-Killer had once used, creating Ultrawoman Grigio Darkness from Grigio's light, and them allowing them to fight.
