Gondii came to Earth to trick Crypto and Orthopox into believing that he was a real Efficiency Expert, who claimed that he was there to test Crypto's abilities. Gondii's true purpose was to get Crypto to finally fail a test in order to get them to leave their mission on Earth to himself. They started testing in Harbor City, then Fairfield, Fantasy Atoll, and Vietmahl. Later on, Pox found out that Gondii was a fraud, which lead to Crypto gunning him down in Vietmahl's Jungle. Pox revealed that Gondii had contacted the Furon Homeworld and informed the Furon Empire of his treachery, so that his clone would be sent to the Homeworld's prison moon. The clone was Gondii's last as it spent its life in jail.
Gondii was very arrogant and often berated Crypto for not being able to live up to his standards. Gondii was very conniving, since he made himself appear as a genuine Furon Officer.
- Gondii was the Furon who was encountered by Crypto and Pox on Earth, since Gastro was a hologram and Admiral Cyclosporiasis was only contacted by radio.
- Continuing the trend of Furon names, Gondii is named after a Parasitewhich causes Toxoplasmosis.
