Kang

Kang is a Rigellian from Rigel 7. His sister/brother is Kodos. Together, Kang and Kodos try to take over Earth and are usually seen attacking Springfield.

Kang & Kodos have a lot of space weaponry at hand and have their own spaceship. They speak the Rigellian language, which, by coincidence, is identical to English. Although they look identical, Kang has a deeper voice than Kodos.

Kang once impersonated Bill Clinton in order to become elected President of the United States. When Kang was revealed to be an alien, he was still more popular than a third party.

Kang has also been found out to be Maggie Simpson's real father.

Kang and Kodos have both ruled over Springfield until they were found out to not be welcome and fled from their primitive weapons.
