Zadoran

The Zadorans are a sapient alien civilization from the planet Zadora, which is described as a "planet of children".

These short, green-skinned humanoids are technologically advanced, but mentally and emotionally equivalent of 7-year-old Humans. No explanation is given for this. It's possible that they might be a neotenic race, or represent the immature stage of another civilization.

History
A group of Zadorans hired the notorious alien mercenary known as Drekk to abduct Santa Claus, as they wanted to experience Christmas on their planet. Agent K managed to contact them and showed them the joy Santa Claus brought to the children of Earth. Seeing that they could not deny that from Earth's children, the Zadorans cancelled the contract on kidnapping Santa.

Though Santa accepted the idea to give the Zadorans their own holiday, thus serving Earth and Zadora.
