Greenmons

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.

Subtitle: Mutated Plant (変異植物 Hen'i shokubutsu)

Powers/Abilities:

 * Poison Gas : Greenmons can secrete a poison gas from the yellow mark in its center. This gas, while not very lethal, can still cause severe damage to the lungs if exposed long enough.
 * Smothering : Greenmons can literally smother a foe under its great mass, allowing absorption of the body fluids.
 * Stretch : When needed, Greenmons can stretch itself out to be extremely thin. This then allows it to go under doors and inside cracks.

History
The monstrous plant known as Greenmons originated on a small island off the coast of Japan. A group of scientists found it, but in a much smaller flower form. One of the scientists attempted to make it even larger but the flower fed on the gamma rays and turned into a hideous plant creature. The plant creature escaped, ready to feed on the Japanese population! Police couldn’t solve the killings and the Science Patrol was brought in to help. They found trails of green goo near the killings and upon investigation, found chlorophyll within it.

While tracking Greenmons, Arashi was attacked by the creature. His fellow Science Patrol members soon arrived and hit the plant creature with lasers, causing it to fall into the water. Not long after, the creature returned, but had grown to a gigantic size! Nothing could stop it this time as it crashed through buildings and ignored the Science Patrol’s ineffectual weapons.

Hayata soon transformed himself into Ultraman in order to defeat the lethal plant. The hero flew in, drop-kicking the kaiju, quickly starting the fight between Ultra and plant! As the pair battled, Greenmons unleashed its poison gas, allowing the vile thing to fall on top of him in an attempt to smother him. The creature, unable to devour the hero, rose up, allowing the red and silver giant to rise to his feet. With his power rapidly fading, Ultraman unleashed the Specium Ray on Greenmons, causing the massive plant to fall in cascading flames.
