The Kong Family is the name of all Donkey Kong's family and friends. Though some of the Kong Family isn't even related to Donkey Kong, they are considered Kongs. It is a sign of their union as a species, and clan. Once membership is earned, that ape is considered a Kong. They are always fighting the evil Kremling Krew, who is always stealing DK's Banana Hoard, or stealing other Kongs. They don't all appear in all the games, but in some games, most of them are playable or supporting.
