Ca-Mon Green was a planet that was visited on two occasions by the Doctor. The First Doctor visited Ca-Mon Green with Vicki Pallister and Steven Taylor, where they ended a war between humanity and the Kel-T over the mining rights of a mysterious blue liquid that bestowed superpowers. The Doctor returned to the planet in his fifth incarnation, stopping the Kel-T them from gaining superpowers again. (PROSE: The Power Supply)
