Nexo

The Nexos are a sentient cyborg species from the Furon, who were long thought extinct. The Nexos first appeared in Los Paradiso, where they attempted to kill Crypto and Orthopox. They were later seen at the Sunnywood Stadium, along with a Nexo Walker. The Nexo's technology was later encountered in Shen Long, and their source was located at Belleville. It was later discovered that the Nexos were in league with the Furons on the Fourth Ring of Furon.

Types
There were three types of Nexosporidium Warriors, and three types of creatures:

Nexosporidium Warriors
Basic Nexo Infantry, there are three different types: Red the strongest, Blue the weakest, and Green, the common foot soldiers. They were armed with a powerful phase cannon in their right arm and fired rockets at their enemies. The Red Nexos were the largest warriors were only located on the 4th Ring of Furon. The Green Nexos were encountered during missions and when the Alert Level reached Red, while the Blue Nexos only invaded when there was a Red Alert Level. Crypto was able to Body Snatch Blue and Green Nexosporidium Warriors.

Nexo Saucers
Nexo Saucers were Saucers that were piloted by Nexo Warriors. They were armed with twin energy cannons, which strongly resembled Crypto's Plasma Cannons. They served as the Nexo's air force and only attacked when Crypto was in his Saucer.

Nexo Walker
Like a Tripod of the War of the Worlds, Nexo Walkers were massive towering three story cyborg monsters that acted as the tanks of the Nexo's forces. A large six-legged walker was armed with an energy beam that was generated by its "Venom Sacs". They were able to project energy blasts from their mouths, while the first walker that was encountered projected a fiery shock wave. Nexo Walkers had an interesting weak point; their External DNA Collection Receptacles, or "Venom Sacs", which resembled Human Testicles. The only Weapon that was strong enough to pierce the Venom Sac's diamond hard shield was the Ion Detonator. It was unknown whether the Nexo Walkers were driven by Nexo Warriors or if they were actual gigantic creatures.

Nexo Dragon
An alien dragon that was ridden and controlled by Saxon. It acted as Saxon's boss battle and attacked Crypto with missile launchers and fire from its mouth. It was unknown how Saxon was able to tame the dragon or even how he encountered it, without knowing who the Nexos were. It only appeared in Shen Long.

Nexo Squid
A Giant Nexo that came out of the water when Crypto was at Belleville Tower. It was able to use a missile launcher, which was located in its beak and generated an electrical current from its tentacles. That Nexo was only encountered in Bellevelle during a story mission.

The Nexo Squid was piloted by Henri Crosteau, a man who assisted in attacking Crypto and Pox with the Nexos.
