Donkey Kong Jr. is the son of Donkey Kong that first appeared in the arcade game with the same name. He had come to rescue his father following the events of the first arcade game. Donkey Kong Jr. was a regular character in the Mario series for a while but seems to have been replaced with Diddy Kong lately. He never appeared in the Donkey Kong Country series, instead it is hinted that he is the grown up Donkey Kong and that the original DK from the arcade games is Cranky Kong.
