Muruchi (ムルチ Muruchi?) was a fish-like kaiju that debuted in the television series Return of Ultraman.

Appearance
Miruchi was a 48 meter tall fish-like kaiju that was blue in colour, had fins on his back, back head, the elbows, and even the hands are fins (except for the thumbs which are claw-like fingers). Muruchi also has gills on the side face. His eyes are usually orange and red, has a crocodile-like mouth (sort of), has two sharp front teeth from top to bottom, and has three tall fins on the head.

Episode 27: The Urban Merman
Within the depths of the Pacific Ocean, Muruchi was slumbering at the bottom of the ocean, while Gubila ate up the supply of fish in the local sea, which resulting in a parent and child Ragon breaching the surface for food. Disturbed from his slumber, Muruchi awoke and started terrorizing the city. Gubila decided to also leave the ocean from the coastline to attack fish markets in Central Megalopolis and eat their fish in the process, with his and Muruchi’s movements causing earthquakes to occur and spouts of water to erupt from the sewers. Gubila and Muruchi came out from a great distance, so none of them knew they were there together destroying the city. When the young Ragon was getting his prized toy boat from the storage warehouse, he noticed Gubila using his drill to bore his way inside the warehouse and then the child found himself on the monster's drill. When Gubila noticed this, seeing as how the monster was fish-like, he tossed him into the air and then ate him, much to the despair of his parent and the fish market owner. After Gubila was forced to water spout the baby Ragon out from Titan, the baby Ragon landed 9 meters away from the Muruchi. Muruchi, However, spotted the baby Ragon and chased him down. However, the baby Ragon turned large and fought Muruchi. Muruchi was doing good moves to try and kill the Ragon, but the Gubila spotted the two fighting and, noticing that they both were fish-like, Gubila ran up to both of them to try and eat them, but first he ran into Muruchi. Then it was a fight between a baby Ragon, Muruchi, and Gubila. Muruchi was injuring Gubila a lot, but the Ragon forced Muruchi to slumber back to the ocean from his Radioactive Ray. Now, it was only a fight between Ragon and Gubila. The Ragon then managed to defeat the Gubila and knocked him back to the Pacific Ocean. He then turned back to human size and returned with his parent back to the water, along with his toy boat.
