The glorious Planet Namek.
Namek is the home of the slug-like Namekians, also known as Nameks. Namek is first introduced by Vegeta and Nappa when looking for information about the Dragon Balls. It has blue grass, green sky, and is basically the opposite of earth, even though there is oxygen in its atmosphere. It is the place where the original Dragon Balls were made. They are much more powerful on their home planet, with Porunga, Namek's eternal dragon, being able to grant 3 wishes instead of one. The Dragonballs in this world seem to be much larger compared to that of Planet Earth. Namek also seems to never have a night time due to it having three suns and each being up at the sky at alternate times. Namek also seems to only have a very small population due to a climate change that wiped out all Namekians except for Grand Elder and the Nameless Namekian(who was sent to earth).
