Donkey Kong, also known as Ambassador Kong, is a space invader from the planet Nintenduu 64. He invades Earth with Lrrr and other characters. His loincloth is filthy. He fights Mario after he attacks Richard M. Nixon's head using his trademark barrel throwing move.
- He is based on the Nintendo character, Donkey Kong, and some of his appearances show him in this more standard Nintendo form.
- However, his fight with Mario in this episode may suggest that he is more based on Cranky Kong, Donkey's grandfather.
- Monkey Fracas Jr., a game seen being played by Philip J. Fry I in Panucci's Pizza, has a character very similar to DK.
- In "A Bicyclops Built for Two", there is a DK lookalike seen.
- In "Bender's Game", Bender Bending Rodríguez pounds his chest in a very similar way to DK.
