During the E3 2019 Nintendo Direct, Banjo Kazooie was confirmed as a Super Smash Bros. Ultimate DLC character. The duo will be added to the game in Fall 2019.
Their appearance began with a short clip showing Donkey Kong, Diddy Kong, and K. Rool lounging in a hut. It began to shake. When they headed to a window, the iconic silhouette appeared. Initially, it turned out to be the Duck Hunt dog, but then Banjo and Kazooie actually dropped in.
Super Smash Bros. Ultimate is available for the Nintendo Switch.
