Kazooie

Banjo-Kazooie refers to: the bear and bird duo of Banjo the bear and Kazooie the bird, the Banjo-Kazooie series of games they star in, and the first game in the series, Banjo-Kazooie for the Nintendo 64. The duo of Banjo and Kazooie are often seen together, and thus are commonly referred to together in hyphenation. As a playable duo, they will be appearing in Super Smash Bros. Ultimate as the third Fighter's Pass DLC character.

Banjo and Kazooie, as a series and as characters, are owned by Rare Ltd., a former second-party developer for Nintendo. In 2002, Rare was sold to, and the rights of both Banjo and Conker were transferred to the company.

Super Smash Bros. Ultimate
The Super Smash Bros. Ultimate reveal trailer for the duo was shown off during a Nintendo Direct on June 11th, 2019, and they will be releasing sometime in Fall 2019. The reveal trailer heavily referenced King K. Rool's original reveal trailer, with Donkey Kong, Diddy Kong and King K. Rool looking outside a tree house window and seeing a silhouette of Banjo-Kazooie. It is then revealed to be Duck Hunt playing a prank, much like the K. Rool reveal trailer had King Dedede pretending to be King K. Rool. Banjo and Kazooie then appear from the sky, and knock Duck Hunt out of frame, with Banjo holding his signature instrument he's named after, the banjo. The trailer references Banjo's heavy connection and roots to the Donkey Kong series as both were owned by Rareware (now called Rare Ltd.) in the 1990s, and Banjo's first appearance was in Diddy Kong Racing.

Super Smash Bros. Ultimate marks their first appearance on a Nintendo system since 2005's Banjo-Pilot for the Game Boy Advance, and their first physical appearance in a new game since the Xbox 360 version of 2010's Sonic & Sega All-Stars Racing. This will be Kazooie's first appearance in a Mario-series title.

Their moveset and appearance is directly pulled from their two Nintendo 64 titles, Banjo-Kazooie and Banjo-Tooie. Spiral Mountain, the location of their home, will serve as the representation for their stage.

Other appearances
Banjo and Kazooie appeared in the 2000 N-Gang comic "N-Gang vs. Nintendo", where they played on the same soccer camp team with Wario, Yoshi, Princess Peach, Donkey Kong, and Lanky Kong. Mario refereed the match.
