Metroid (species)

Metroid,(メトロイド, Metoroido) are recurring artificial organisms in the Metroid Series (note that the series is named after the organism) that also appear as an Assist Trophy in Super Smash Flash 2.

Character Description
The Metroid were created long ago by an ancient tribe known as 'The Chozo', they were discovered on Planet SR388 years after their creation. This tribe created the Metroid in order to fend of a threat known as 'parasite X'. After the Space Pirates discovered the Metroid, they were promptly used as bioweapons, due to the Energy Leeching abilities the creatures posses.

During Metroid, Samus was send to Planet Zebes to destroy the Space Pirates, as well as dispose the stolen Metroid. During Metroid II: The return of Samus the Galactic Federation noted the danger the Metroid posed, and started to eradicate the Metroid by attempting to destroy their planet, and once again Samus was called for duty. During the last battle with the Qeeun Metroid, and infant Metroid hatched and imprinted Samus as her mother, this Metroid because known as 'The Hatchling' and would become one of the most important Metroid in the series, as well as the last one.

In Super Smash Flash 2
A Metroid can be released from an Assist Trophy. After being released, it will fly around, and eventually latch onto the head of one of the opponents. Once latched, the Metroid will start draining Life Energy, racking up the damage meter of the opponents. Movement is also hampered when a Metroid latches onto a character.

The Metroid appears and acts exactly like it's appeareance as an Assist Trophy in ''Super Smash Brothers Brawl. ''

Note that Metroid can be attacked in Super Smash Flash 2.
