The family is initially formed by Cranky Kong's great-grandfather. When Cranky married Wrinkly Kong, the family raised a son named Donkey Kong Jr., he became the Donkey Kong in which he became the current family leader and his nephew Diddy Kong as newly leader.
After the Kremling Krew appears, the Kong Family has become a resistance group against any invader who want to take over the island and its resources. With this, individuals of other species began to be allies of the family, such as: Brothers Bear, Banana Bird Queen, K. Lumsy, Timber & his gang and Xananab who were helped.
