Donkey Kong (universe)

The Donkey Kong universe refers to the Smash Bros. series'  collection of characters, stages, and properties that hail from the sub-franchise of the Mario series that deals with the character Donkey Kong. It is generally agreed on that Donkey Kong and related items count as Mario properties, but DK has appeared in enough of his own games alongside enough original characters, created by second-party developer Rareware instead of Nintendo itself, that many consider him as holding sway over a "sub-universe" of Mario.
