Donkey Kong Jr. (sometimes referred to as DK Jr. or just Junior) is the son of the original Donkey Kong and the implied father of the current Donkey Kong. He first debuted in Donkey Kong Jr., an arcade game first released in 1982. He has yet to make any playable appearances since Mario Tennis.
Donkey Kong Jr.'s premier appearance is in the eponymous Donkey Kong Jr. He is the star of the game and the only playable character. It follows the events of the original Donkey Kong, where Donkey Kong Jr.'s father, Donkey Kong, has now been locked up by Mario. Donkey Kong Jr. must travel through four stages, climbing vines to ascend them and then watching as Mario hauls his father further on through the game.
There are numerous enemies that Donkey Kong Jr. must avoid. However, if he drops fruit on the enemies, they will be defeated. Once Donkey Kong Jr. has put a key into the cage, Mario will move further on. When Donkey Kong Jr. beats Mario at last in Stage 4, Donkey Kong and Mario both fall; Donkey Kong Jr. catches his father and then walks off-screen with his newly-freed papa.
In Donkey Kong '94, he helps his father kidnap Pauline again and to beat Mario but is later redeemed.
