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 Officer.
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 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 finally Vietmahl. Later on, Orthopox finds out that Gondii is a fraud, which leads to Crypto gunning him down in Vietmahl's jungles. Pox reveals that he had contacted the Furon homeworld and informed the empire of his treachery, so his clone would be sent to the Homeworld's prison moon. The clone would be his last as it spends its life in jail.
