Since Kazooie lacks a hurtbox of her own for every action except Talon Trot, Banjo can make use of a disjointed playstyle with a great many of his attacks.
Wonder Wing has priority over almost every attack in the game, which makes approaching projectile characters easy.
A third midair jump allows for an easier time recovering, as well as the ability to turn while in the air.
Shock Spring Pad does not put him in special-fall, which can be good against ledgeguarding characters.
Breegull Blaster cancels all of their other moves while active, which can leave them open to attack if an opponent has a reflector or projectile-cancelling ability.
Their Side Special, Wonder Wing, has a maximum number of uses at 5, which cannot be refilled without losing a stock.
They can damage themselves with Rear Egg.

Banjo & Kazooie's code name within the game's files is "buddy", due to being the only duo so far in the Fighters Pass.
Ultimate marks Banjo & Kazooie's first physical appearance in a decade, as their last playable appearance was in the Xbox 360-port of Sonic & Sega All-Stars Racing, released in 2010.
It is also their first appearance on a Nintendo console in over 14 years, last appearing in Banjo-Pilot on the Game Boy Advance in 2005.
Banjo & Kazooie are the first characters:
To come from a Western-developed series, as Rare is localized in the United Kingdom
To be owned by one of Nintendo's rivals in the console and game-publishing markets
By extension, they are the first third-party characters to have once been a second-party series by Nintendo before Microsoft's purchase of Rare.
To not have any of the games in their series to be available on the Nintendo Switch
Joker fit this criteria as well at the time of his release until Persona 5 Scramble: The Phantom Strikers came out in Japan
To vocalize while dashing
Banjo & Kazooie’s reveal trailer is a sequel to King K. Rool’s own reveal trailer, as a nod to Rare being the developers of the original Donkey Kong Country trilogy and the Banjo-Kazooie series. Their introduction tagline, "Banjo-Kazooie are raring to go!", is also a reference to Rare.
Interestingly, the tagline refers to them as Banjo-Kazooie, the name of their game series instead of their actual names separated.
Banjo & Kazooie are the first DLC fighters to have repurposed voice lines as opposed to new lines recorded specifically for Smash. Min Min would later follow suit.
Kazooie, along with Falco and the duck from Duck Hunt, are the only playable avian characters in Smash.
When performing a successful parry, Banjo's pose resembles an Extra Life from Banjo-Kazooie.
When dashing, the flames that emit after consuming a Superspicy Curry will shoot backwards. This is due to Banjo being the one to eat the curry and is facing backwards during Talon Trot.
Banjo & Kazooie's Classic Mode route theme is shared with the Ice Climbers, being opponents comprised of duos.
Banjo's backpack has a second flap at the bottom that opens up for Kazooie to perform Talon Trot and Grenade Egg, which is unlike the original series. According to Steve Mayles, the creator of Banjo-Kazooie, he initially wanted to do this but couldn't add the additional joint due to the Nintendo 64's hardware limitations.
Kazooie can be seen waving at the camera when they use the Dragoon.
Banjo & Kazooie and the Hero are the first DLC fighters to appear in the CGI portion of another DLC fighter's reveal, being Sephiroth's, with Min Min following suit in Kazuya's trailer.
