Speaking "Rigellian", which coincidentally sounds exactly like English, Kang and Kodos are Rigellians from the planet Rigel VII. Virtually identical in appearance, wearing breathing helmets, one of the few distinguishing characteristics is the duo's voices as Kang's is deeper. In most appearances they are antagonistic towards humanity. One exception is Kang and Kodos's first appearance in segment "Hungry are the Damned" of the episode "Treehouse of Horror", where they capture the Simpson family and feed them exquisite cuisine. Lisa becomes suspicious of their intentions and accuses Kang and Kodos of wanting to eat the Simpson family. Kang and Kodos deny this accusation and are outraged. Afterwards both take the Simpsons back to Earth. Kang and Kodos have invaded the Earth on several occasions, with varying results. In 1996, Kang and Kodos impersonated Bill Clinton and Bob Dole and ran against each other in the 1996 election. At first, Americans declared they would vote for a third party candidate, but Kang convinced them that the option would be a waste of a vote. As a result, Kang was elected president. In their second appearance, they decided to take over the Earth after citizens had declared world peace, but ultimately failed. Kang and Kodos's religion is "Quantum Presbyterianism", although Kodos later claims to be Jewish. Other Rigellians that have appeared include Serak the Preparer, who was voiced by James Earl Jones and only appeared in "Treehouse of Horror".
