Dixie Kong originates as Diddy Kong's inseparable friend and partner in Donkey Kong Country 2: Diddy's Kong Quest. She stood out from the rest of the playable Kongs by using her blonde ponytail as a propeller to briefly hover in the air. This is mostly used to help with alignment to land on platforms. She went on to appear in the starring role in Donkey Kong Country 3: Dixie Kong's Double Trouble! alongside Kiddy Kong. Since then, she has been one of the main recurring characters of the Donkey Kong franchise, as well as minor appearances in the Mario franchise. Her original design in the SNES games had her beret feature a Rareware pin to coincide with Diddy Kong having the Nintendo logo across his hat, though this feature was removed in all of her appearances following Rare’s acquisition by Microsoft in September 2002.
Dixie is very brave and has a love for adventure, especially with her boyfriend Diddy Kong. She is also friendly with most other Kongs, particularly her cousin Kiddy Kong and her younger sister Tiny Kong. While Dixie can be childish and a diva at times, she is also very energetic with a tomboyish streak, participating in many sports and always ready to pick a fight. She loves gumballs, always blowing bubbles and even using them as ammunition for her gun. She also knows how to play the electric guitar and is seen playing one several times.
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 referenced 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 appears as two spirits (one of herself and one of her and Kiddy Kong on a raft) and was referenced as one of Diddy’s color schemes again, and her hat, hair, and ponytail appear as Mii Fighter headgear.
