Gondii is very arrogant, often berating Crypto for not being able to live up to his standards. He's very conniving, since he made himself appear as a genuine Furon efficiency expert.
Gondii came to Earth to trick Cryptosporidium and Orthopox into believing he was a real Efficiency Expert, who claimed he was here to test Crypto's abilities. His true purpose was to get Crypto to fail a test in order discredit them, so he can take over their DNA harvesting operation. They started testing in Harbor City, Fairfield, Fantasy Atoll, and finally Vietmahl, but Crypto manages to barely pass all of the tests, much to Gondii's disappointment.
Later on, Orthopox finds out that Gondii is a fraud, which leads to Crypto relentlessly chasing him and shooting his shields until he dies in Vietmahl's jungles. To stop his clone, Pox contacts the Furon homeworld and informed the Imperial Guard of his treachery, so his clone would be sent to the prison moon of Gorta.
- Gondii is the first flesh and blood Furon that's encountered by the main characters on Earth, since Gastro was a hologram and Admrial Cyclosporiasis was only contacted by radio.
- Continuing the trend of Furon names, Gondii is named after a parasite which causes Toxoplasmosis.
