About Banjo-Kazooie in Smash
Banjo & Kazooie are a duo that fights together as a singular character, like Duck Hunt. The duo is a heavyweight weighing as much as Snake and R.O.B. While their walking speed is below-average, and their initial dash and traction values are both among the worst in the game, they have a very fast running speed, courtesy of Kazooie’s Talon Trot, which is fairly uncharacteristic of their weight class.
While Banjo is somewhat short for a heavyweight (having a relatively average size), his hurtbox is still fairly wide nonetheless, much like Wario. Outside of the Talon Trot and up tilt, Kazooie does not have a hurtbox, meaning that all standard attacks involving her are disjointed.
Akin to Ridley and Charizard, the duo has two midair jumps. Additionally, they have a fast falling speed, high gravity, slow air speed, and average air acceleration.
