Noiseler is a bat-like Kaiju that appeared in the TV series, Ultraman 80. He first appeared in episode 7. A space monster with a particular affinity to certain noises, Noiseler became agitated by the sounds of human technology, causing him to become extremely aggressive. Fortunately, Ultraman 80 intervened, and even though he very nearly lost the fight, the sound of his Color Timer finally calmed Noiseler down, and he returned to space peacefully.

Noiseler was a space monster that lived during Ultraman 80's time on Earth. The creature first made his presence known when Noiseler flew past Earth when a hiker saw a strange shadow fly over a jet plane. Moments later, the plane was destroyed in an explosion. Meanwhile, Yamato was forced to make a group of his students that he formed a band with stop playing, due to disrupting people in the surrounding area. UGM soon learned of this occurrence and set out to figure out what was going on.
