Kodos (pronounced Koh-dohs) is a Rigellian from Rigel VI. She is the sister of Kang. Kodos has been referred to as both male nd female. 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.

He went to summer camp with Roger and are friends with Lrrr and Ndnd


Kang and Kodos once impersonated Bob Dole and Bill Clinton respectively in order to become elected President of the United States. When they were revealed to be aliens, they were still more popular than a third party.

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

The Simpsons GameEdit

Kodos (along with Kang) appears at the end of Mob Rules, when they cause Dolphins to attack humans, cause Lard Lad to assault the industrial zone of Springfield, and invade the mall. However, when they were thwarted, they decided to start attacking Springfield. This causes the Simpson family to enter the game engine to find the creator, but Groening wasn't enough to defeat the aliens because he didn't want to. Soon after God is defeated, God decides to replenish Springfield, returning peace to the city. Kodos is male here.


The Simpson Alien Line Up

Alien Line up

  • Kodos has been referred to as both male and female. Female in Treehouse of Horror XVIII and male in Treehouse of Horror XVIII, though this may be due to humans being unable to tell male and female Rigelians apart. Also, Kodos mentioned his/her "700 testicles" in "Treehouse of Horror XVIII", however, in Treehouse of Horror XXII, Kamala, a female Rigelian, also made a reference to having testicles.
  • In several DVD commentaries, Matt Groening and other writers confirm that Kodos is indeed written as female, as consistently as possible.
  • Matt Groening had an idea about Kang and Kodos appearing on Futurama, but strangely they never did.
  • In the video game, Simpsons Hit & Run, Kodos works with Kang to make an Intergalactic reality show in Springfield, Foolish Earthlings and is killed in the production due to the actions of Homer's plans of using nuclear waste to destroy the UFO.
  • The character is named after Kodos the Executioner, a human villain from Star Trek.


  1. While both have been referred to as a male, in "Treehouse of Horror VII" Kodos was introduced as Kang's sister. However, this has been contradicted in several episodes both before and since. The episode "Simpsorama" refers to both of them as female.
