First Appearance: Episode 5 "Secret of the Miloganda"
Greenmons (グリーンモンス Gurī-n Monsu) was a monster that appeared in the Ultraman television series. The creature was an animate plant that started out man-sized, but eventually grew to giant-size. It was green, somewhat amorphous though roughly round, and had a glowing yellow center. It emitted a low roaring sound. It attacked by issuing a poison gas cloud from its glowing center, possibly containing spores of some sort. Ultraman eventually defeated it using his specium ray.
