My interpretation of Sabito as Dawie is someone who thinks hes cool and tries to always come across that way.

In canon Sabito was friends with Giyu and in my dub Giyu - called Gawie, thinks he is cool, and he is.

Whereas Gawie tries to "play" things cool without seeming to try to hard to do so and is generally reserved, Sabito/ Dawie on the other hand is very animated, brash, energetic and tries a little too hard to be cool, even trying to come up with "cool lines" while hes doing something cool.

So hes voice has to be a mix of arrogance and some dude who really thinks hes cool but just not be.

His laugh has to be either an annoying or funny laugh
