Mogrudon and his first appearance in Ultraman Cosmos was referenced by Hikaru Raido and Ultraman Taro in New Ultraman Retsuden episode 18 to compare Ultraman Ginga's Ginga Comfort with Ultraman Cosmos's Full Moon Rect.The Mogrudon suit was on display at Ultraman Land.During Chaos Darkness's final attack on Earth, Mogrudon (as well as Lidorias and Bolgils) assisted Ultraman Cosmos in weakening Chaos Darkness long enough for Ultraman Cosmos to purify the evil entity once and for all. During his time on the island, Mogrudon made good friends with the monster Bolgils. Mogrudon was then sent to Kaburaya Island where he would live with other monsters that's rampages were stopped by Cosmos. Despite Mogrudon using his illusionary chest and tail, Cosmos fought back and incapacitated Mogrudon by tying him up with his own tail before putting the monster to sleep with the Full Moon Rect. Unfortunately, Mogrudon hit a power plant while being dragged to the surface and EYES was out of commission, leaving Musashi to transform into Ultraman Cosmos to deal with the monster. EYES then tried 'fishing' the monsters out from hiding by using a giant hooked cord, like a fishing rod and successfully managed to pull Mogrudon's entire body to the surface. EYES was quick on the scene to try and drive off Mogrudon's presence but his tail retracted back into the ground before any threat could be made towards the monster. In hopes of silencing the noise, Mogrudon tried to stop the construction with his long tail on the surface.

Mogrudon was a giant mole monster who was disturbed of his sleep by electromagnetic waves caused by underground construction.
