Banjo is a laid-back, well-mannered brown bear who loves honey and, as his name suggests, playing his banjo. He is generally non-confrontational, desiring peace and quiet, and he often helps those in need, but he is strong enough to defend himself if need be. He is a foil to the sarcastic and loudmouthed Kazooie, his best friend whom he (often unwittingly) goes on adventures with. He lives with Kazooie and his younger sister Tooty in a small house near the foot of Spiral Mountain.
Banjo chronologically first appeared in Diddy Kong Racing as one of the eight starter characters, which takes place before his partnership with Kazooie. He and Conker the Squirrel were recruited by Diddy Kong to help defeat the intergalactic pig wizard Wizpig. He is the second-heaviest character, and races in aqua-colored vehicles.
His first proper adventure, however, occurred in Banjo-Kazooie. The evil witch Gruntilda, upon hearing that Tooty is the prettiest girl of all, kidnaps her and attempts to use a machine to steal her youth and beauty. Banjo oversleeps while this is happening, but soon awakens and begins his journey to rescue his sister. With the help of Bottles, the move-teaching mole, Banjo and Kazooie navigate through Gruntilda's Lair, a complex cavern in Spiral Mountain with links to many disparate worlds. Throughout the lair, Banjo acts as mostly a platform for Kazooie's attack and movement abilities; he himself does little more than run, swim underwater, and talk to the various inhabitants of each world. The friendly shaman Mumbo Jumbo also transforms Banjo into various creatures and objects, allowing him to bypass certain obstacles. After the pair get through the lair and confront Grunty at its peak, they ultimately summon The Mighty Jinjonator to push her off the tower to her doom; she crashes into the ground and is buried by the ensuing debris.
Two months later in Grunty's Revenge, Gruntilda's ogre-like minion Klungo creates a robotic body for her spirit to possess while her body remains underground. This newly-built "Mecha-Grunty" kidnaps Kazooie and travels 20 years into the past to stop the two from meeting, thus preventing her defeat. Mumbo uses his magic to send Banjo back in time and stop her. Banjo is necessarily more of an independent character in this adventure, able to defend himself alone until he manages to rescue Kazooie. The duo eventually send Grunty's spirit back to the future into her real body, restoring the timeline mostly back to normal.
Two years later in Banjo-Tooie, Gruntilda's sisters appear to rescue the now-skeletal witch, who promptly attacks Banjo's house and kills Bottles. Banjo and Kazooie set out again to chase down the witches, who are attempting to restore Grunty's flesh by using a Big-O-Blaster to suck the life out of the entire Isle O' Hags. Bottles' brother Jamjars helps the duo learn to work independently, giving Banjo several Kazooie-free moves that utilize his backpack to attack, relocate unwilling cargo, sleep to regain energy, and protect him from dangerous liquids. Banjo and Kazooie triumph over Grunty once again, and use the B.O.B. to revive Bottles.
Eight years later in Nuts & Bolts, the duo has become lazy and out of shape from their lack of exercise, having forgotten their moves from the previous games. Grunty reappears as just a skull and attempts to start a fight, but before they can, they are interrupted by the Lord of Games (L.O.G.), the supposed creator of all video games. He creates a robotic body for Grunty and a series of vehicular challenges for Banjo and Kazooie to go through. Banjo acts as the driver for all vehicles and can train at Boggy's Gym to improve his physical attributes, though with the game being vehicle-based, this is of dubious usefulness. The pair eventually battle and defeat Grunty, who is forced to work in L.O.G.'s video game factory, and earn back their old moves.
Although Banjo & Kazooie do not make any sort of appearance in Super Smash Bros., the game's Japanese website included them in a poll to gauge interest for potential playable characters in a sequel.
Despite Banjo & Kazooie collectively being the second-most requested Rare characters in the aforementioned SSB sequel poll (surpassed only by the GoldenEye 007 version of James Bond), they were not included as playable characters. According to Super Smash Bros. series creator Masahiro Sakurai, "Incidentally, including a character from Rare in Smash would be difficult for various reasons. I know there are some people who think that Banjo & Kazooie are an obvious inclusion, but that's unlikely for a variety of legal and financial reasons."
As a playable character

Banjo & Kazooie make their debut as newcomers in Super Smash Bros. Ultimate, with their and the Hero's inclusions being announced during the E3 2019 Nintendo Direct on June 11, 2019. He and Kazooie are collectively the third DLC characters of Fighters Pass Vol. 1, and were released on September 4, 2019.
Like in Banjo-Kazooie and Banjo-Tooie, Banjo provides the duo's basic movement and uses his Claw Swipe and Forward Roll, the latter of which function as his neutral attack and dash attack, respectively. However, he also performs a few maneuvers by himself that are unique to Ultimate, with the most notable examples being his forward aerial, down throw, and back throw.
According to Masahiro Sakurai, Banjo & Kazooie were heavily requested characters for a long time even leading up to Ultimate's launch, particularly in the West. Even after character reveals like Ridley and King K. Rool, requests for Banjo & Kazooie still kept coming in. While their inclusion would have been a natural one in the past, this was complicated by Microsoft's purchase of Rare in 2002, during which it was originally thought that Nintendo shouldn't collaborate with their console competitors.
However, thanks to Rare and Microsoft's cooperation, the rights to Banjo & Kazooie were easily secured, as Microsoft had developed a strong third-party relationship with Nintendo leading up to their reveal in Ultimate. Phil Spencer, the head executive of Microsoft's Xbox division, had actually voiced his support for their inclusion in the Super Smash Bros. series in 2015 around the introduction of the Fighter Ballot and again in 2018 following Ultimate's teaser announcement. Soon after their official reveal, Spencer said, "There wasn't anything kind of CEO-to-CEO that had to happen" in order for Banjo & Kazooie to join Ultimate, courtesy of Microsoft's increasingly positive relationship with Nintendo's third-party team.
In their gameplay showcase on September 4th, 2019, Sakurai openly acknowledges the fact that the Banjo-Kazooie intellectual property is completely owned by Microsoft. He also acknowledges Rare and Microsoft's cooperation in bringing the franchise into Super Smash Bros. Ultimate, as they were happy to see the duo in the game and saying Rare welcomed Nintendo with open arms. He even notes that if those interested in the series want to play the original titles today, they should do so in Rare Replay on the Xbox One.
