Koichi Oki

is one of the main characters from Ultra Galaxy Mega Monster Battle. He is a member of ZAP SPACY.
==Personality==
Oki has an active and enthusiastic personality, and is a monster enthusiast who excels at storing monster data on his computer and filling his room with monster models and self-made replicas.
During his university years, Oki specialized in monsterology and paleontology, and had a detailed understanding of various characteristics of monsters such as their behavior, calls, and footprints. He was very curious about extinct monsters, and even in dangerous situations, he would feel excited to meet and witness their abilities. Additionally, he was very familiar with the existence of Ultraman.
However, he sometimes forgets names of mechanical enemies and extraterrestrial creatures, as his focus is on biological knowledge of monsters. Moreover, he may occasionally misunderstand the situation, which makes other team members consider him a troublemaker.
==History==
===Ultra Galaxy Mega Monster Battle===
As the youngest member of ZAP SPACY, Oki serves as a communications and control specialist, assisting in the completion of various missions. When the team arrives on planet Boris and meets Rei, Oki uses his knowledge of monsters to form a friendship with him. As the plot develops, he deduces that the giant appearing in the vision is likely "Ultraman".
Although he may sometimes be troublesome in different situations, he has extensive experience in monster knowledge and can provide powerful support at critical moments. In his free time, he also enjoys playing games similar to giant monster battles with Kumano. In addition, he once assembled Chandlar's skeletal specimen model, demonstrating a deep interest and professional knowledge in the field of monsterology.
===Ultra Galaxy Mega Monster Battle: Never Ending Odyssey===
After escaping from the planet Boris, Oki continued to serve as a member of ZAP SPACY in space for a month, performing various tasks such as maintaining the ZAP space station and its cosmic base. 
Although he remained a monster enthusiast, he learned to consider the atmosphere when talking to people, avoiding inappropriate remarks. Having experienced past events, he began to develop an interest in the existence of alien, even going as far as creating a model of an Alien Zarab.
During the attack on the cosmic base, ZAP Bon was attempting to detain Rei, who was controlling the monsters, as a dangerous criminal. Oki and the other members managed to escape in the Pendragon just in time. Later, they successfully rescued and interrogated the mastermind behind the attack, Dail. With Dail's guidance, they finally arrived at the planet Hamal and rescued Hyuga and Rei, reuniting the members of ZAP SPACY.
Subsequently, Oki and other ZAP members are then taken hostage by Alien Pedan, but Dail comes to the rescue and sacrifices himself under enemy fire. Dail's helmet was placed on his grave as a memorial, and the crew of ZAP SPACY paid their respects to him.
After experiencing the threats of the Alien Reiblood incident and the Rheonics Battle, Oki and the other members continued their journey through space with the goal of returning to Earth. 
===Mega Monster Battle Ultra Galaxy: The Movie===
After Oki and the members of ZAP SPACY fought with Alien Reiblood, they landed on a planet called Dent. However, their visit is soon interrupted by Zaragas, who appear from within a meteor. Zaragas was successfully defeated under the attack of ZAP SPACY. They are, however, startled by the sudden appearance of Ultraman Mebius and witness the moment when Rei is taken away by Mebius.
To help Rei, Oki and the other members decide to go to the Monster Graveyard. Suddenly, Alien Zetton and his spaceship, Nurse, attack the Space Pendragon. Fortunately, Shin Asuka appears and easily defeats Alien Zetton, and later transforms into Ultraman Dyna and helps ZAP SPACY go to the Monster Graveyard. Upon arriving, ZAP SPACY members assist the Ultras and Rei in battle with Ultraman Belial.
After the incident is over, he and the members briefly visit the Land of Light.
