Nexosporidium

Nexos are Furons that are very stupid. They were supposedly extinct however this is proved to be untrue. They serve two masters: meningitis and Creusto (both deceased.) According to creusto their original purpose was to protect Earth rather than destroy it like most furons. As for Emperor meningitis they serve as mere guards for the palace.

Variates
Warriors Warriors were the first Nexos Crypto encountered. Unlike most Nexos they also have color variations (Red, Green, Blue) this however does not differ the in strength. Nexo warriors are equipped with a lazer cannon, a jet pack, and a missile launcher. They also can teleport to different areas. Nexos speak gibberish but sometimes English words can be heard.

Walkers Walkers are very large spider like creatures the only possible vulnerability from the ground is the DNA collection recepters,located on it's hind legs, resembling the scrotum sack of a human being. They have lazer beams coming from their mouths, are able to pound the ground and start an eight meter radius circle around them with flames, They are very large and ironically can spread a "poison" from their lazers to protect humans which they dump into the river.

Squid Technically not a Nexo as it is not sentient but a robot controlled by Creusto. The squid stays in waters and can fire lazers from it's tentacles and bombs from it's mouth.

Dragon Like the Squid it is technically not a Nexo as it is also not sentient. Saxon used it not knowing exactly what a Nexo was. If approached the dragon lets out a shield that is not deadly but causes all technology to shut down completely. It can throw Fireballs if thrown back somehow, the dragon's shields shut down temporally and is vulnerable to all weaponry.

Appearances
Apparently they appeared before destroy all humans. In destroy all humans POF the warriors appear during the storyline. The Nexo walker makes an appearance that actually is important. The first in sunny wood where Crypto has destroy it, the next in Belleville where Crypto has to destroy the Nexos from his saucer before they release the poison into the water supply. The third is in the fourth ring of Furon as an odd job.
