Dixie Kong appears as a trophy.
Dixie was a scrapped design for a playable character, as evidenced by leftover references for "dixie". According to Sakurai, Dixie Kong was intended to be teamed with Diddy Kong, where the two could be tagged out for each other in the midst of battle, similar to how they played in Donkey Kong Country 2: Diddy's Kong Quest; the idea, however, was cut after he ran into technical issues with implementation of the idea, and only Diddy Kong appeared as a solo fighter in Brawl.
Dixie Kong reappears as a trophy in both versions, and as a color scheme for Diddy Kong. Additionally, in Super Smash Bros. for Wii U, Dixie Kong appears as a red Smash Tour item, which gives the user an extra double jump for the duration of a battle.
Dixie Kong originates as Diddy Kong's girlfriend and sidekick in Donkey Kong Country 2: Diddy's Kong Quest. She went on to appear in the starring role in Donkey Kong Country 3: Dixie Kong's Double Trouble!. Since then, she has been one of the main recurring characters of the Donkey Kong franchise.
