- Origin: Yapool's dimension → Tokyo Shinjuku Building town
A monster that belonged to the Alien Antira. Zaigon went on a destructive rampage after being unleashed in the middle of a city. TAC was quick to respond to the situation, but were also put at bay by Zaigon's flames. As they were going to fire their new weapon on Zaigon, they encountered Hideki Go, the human host of Ultraman Jack. While Goh's face was burned by Zaigon's flame, Goh managed to use a laser on Zaigon, causing the choju to disappear. In reality, the monster had teleported away to recover by his master. However after Alien Antira's identity as Fake Hideki Goh was exposed, he summoned Zaigon again to take care of TAC. TAC tried to kill the choju via planes but with no success. After Alien Achira was killed, Hokuto and Minami transformed into Ultraman Ace and battled with the rhino-like choju himself. Ace then proceeded to taunt Zaigon by using a red flag as a cape, bullfighting with the choju, but the taunting didn't last long after Zaigon used his flames. After shooting the choju in the mouth, Ultraman Ace decapitated Zaigon with his Ultra Knife. Ultraman Ace then took Zaigon's head and erected it as a tomb for the monster.
- Zaigon's costume would be modified into Hanzagiran.
- Zaigon's debut episode (as well as the Alien Antira incident) would later be copied in episode 5 of Ultraman: Towards the Future.
