Kiruan

Kiruan appeared in 1983 movie called Return of Ultraman. Kiruan (キルアン), also called Bug Jewel (バグジュエル Bagu Jueru) by the attack team, is a kaiju that appeared in the fan-made Daicon film, Return of Ultraman.

Kiruan was formerly a normal insect that had somehow ended up in Tokyo's sewage system. A meteor from space crashed near its location, and the rock unleashed mysterious gases. The gas caused Kiruan to grow so large that its head broke through the streets into aerial view. An attack team who had come to investigate the meteor attempted to subdue the creature, but they no match for it. The monster used its prehensile tail to knock down one ship and pull another underground as it fled. Later the next day, Kiruan reappeared fully grown and much more powerful than before. The attack team attempted to fight it off again, but were still outmatched. When one of them was about to suicide and sacrifice themselves to kill Kiruan with a bomb, he was stopped. The ship had been grabbed by Ultraman to stop the man from destroying himself. Ultraman put the ship down and went to fight Kiruan. The monster proved extremely tough, summoning a shield to block all of the Ultra's deadliest attacks. Eventually Ultraman figured out how to break through it, throwing the bomb from earlier to destroy the shield. He then fired his finishing Specium Ray causing Kiruan to finally be destroyed. Ultraman then went back to normal undercover with that attack team.
