List of Mega Monster Battle characters

Mega Monster Battle (大怪獣バトル, Daikaijū Batoru) is a multimedia project of Tsuburaya Productions' long-running Ultra Series. The story's main setting took place in the mainstream Showa Universe (Ultraman to Ultraman Mebius) where monsters on Earth went extinct after 500,000 years had passed. Humanity at that time began to colonize the outer space area and an event called Galaxy Crisis (ギャラクシークライシス, Gyarakushī Kuraishisu) took place, where Alien Raybrad summoned Bullton and caused monsters and aliens from the Ultra Series multiverse to appear randomly.

The Mega Monster Battle multimedia work includes:

Rei (レイ) is a human Reionics, ZAP Spacy's latest member and the main protagonist of Ultra Galaxy Mega Monster Battle and its succeeding series, Ultra Galaxy Mega Monster Battle: Never Ending Odyssey. He was once a baby that appeared during Bullton's attack on Planet Boris. During the series, he first appeared after being trapped inside the carcass of a Peguila and in amnesiac state, appearing to be hostile towards ZAP Spacy members despite saving their ship, Space Pendragon, twice while only cares about recovering his forgotten background. In the end, after being persuaded by Hyuga, Rei decided to join ZAP Spacy. During his membership within the ZAP Spacy crew, he was haunted by the image of the giant buried in the rock and challenged by a mysterious woman named Kate. At the end of the series, after defeating Kate, he discovered the woman as his older sister and the buried giant is Ultraman, whom asked his help to free him. Rei as well had awakened his true potential as a Reionics, becoming a figure known as Reimon (レイモン). During the second season, Rei participated into the Reionics Battle to determine the successor of Alien Raybrad to conquer the galaxy. Among them was Grande, an Alien Keel whom claimed to be his rival. Unlike the others, Rei on the other hand competed in the battle only to face Alien Raybrad, not wanting to inherit the latter's role as the ruler of the galaxy. In the middle of the series, he also encounter another giant, Ultraseven, which he rescued from Armored Darkness. After facing Alien Raybrad, he was finally brought to Earth for the first time. Sometime later in the movie, having recently finished Zaragas, Rei was spirited by Mebius, as he was predicted to be the chosen one capable of defeating Ultraman Belial. However, during the remaining Ultras' battle against Belial's army, he was corrupted by Belial into joining his legion until ZAP Spacy members awakened him from his senses. Followed by the arrival of Zero and the Leo Brothers, Rei was able to hijack Belial's Giga Battle Nizer to ease the Ultra's battle, allowing Zero to finish him.
