His neutral attack...

Is his basic combo from the first game...

While his jab...

Is his basic attack from Banjo-Tooie.

Moving on to the tilts, side tilt is...

A reference to the beak bayonet attack from Banjo-Tooie's FPS segments...

Meanwhile the down tilt...

Comes from the Beak Barge!

Even the duos running animation...

pulls from the iconic Talon Trot!

The dash attack as well...

Was a dash attack in the original game

His smash attacks only have one clear reference...

being the breegul bash from Tooie, specifically one of the attacks locked behind the infamous stop n’ swop. (Don’t feel too bad for Kazooie, as according to RARE, she likes it!)

It should be noted though that his up smash...

seems to make reference to the beak drill attack introduced in Tooie but it’s pointed upwards instead of downwards.
