File:Planet Kanassa.png

Planet Kannasa is the planet Bardock and his crew are seen conquering in Bardock: The Father of Goku. It is inhabited by a fish-like race with telepathic abilities called the Kanassans. Prior to the genocide that took place there, the inhabitants were able to foresee the coming destruction that would occur on the night of a full moon. This turned out to be an accurate prediction, as Bardock's crew were able to use the light of the full moon to transform into their Great Ape forms and exterminate the planet's residents. After conquering the planet, Bardock was given psychic abilities by the sole survivor so that he could see the horror of the end of his own planet — Planet Vegeta. The conquering of this planet also signified to Frieza that Bardock and his crew were becoming even stronger than the Elite Saiyans.
