Greenmons (グリーンモンス Gurīnmonsu?) was originally a carniverous plant called Miroganda (ミロガンダ Miroganda?) that was mutated into a kaiju by gamma radiation. Greenmons then committed the murders of the scientists that brought him to Japan, before being stopped by Ultraman. Subtitle: Bizarre Plant (変異植物 Kaiki Shokubutsu?)
