Subtitle: Space Monster (宇宙怪獣 Uchū Kaijū)
Groteng was one of many monsters placed in the monster asylum by the U40 warriors. Once the Imedo Beings hijacked the asylum, they set it toward Earth and released the monsters from their imprisonment. Shortly after this, the Scientific Defense Guard landed on the planet surface they were assaulted by monsters with Groteng among them. Once Goadarion was destroyed by Ultraman Joneus, Groteng was sent with Jinario and Plazoon to slay the hero. With Joneus tired he eventually fell to the three monsters before the kaiju rampaged through Tokyo. Once Joneus had recovered, Loto and Elek assaulted all three monsters and destroyed them simultaneously by throwing them together and finishing them with their Lotoria and Helium Rays, respectively.
