Diddy Kong
K. Rool, along with Donkey Kong and Diddy Kong, are featured prominently in Banjo and Kazooie's "Super Smash Bros. Ultimate" reveal trailer, titled "Best Friends". This trailer continues where K. Rool's trailer left off, showing the Kremling King sleeping in Donkey Kong's treehouse alongside his nemeses. All three characters celebrate their reunion with Banjo and Kazooie, who have connections to the "Donkey Kong" universe via "Diddy Kong Racing" and Rare.
