What Was Puar's Reason Of Existence?

[Sovran Nila]

Full disclaimer: I've never researched this aspect before, hence why I'm asking it now for the sake of discussion.

Why did Puar exist? What is Puar actually? What was Puar's role throughout the series? Was Puar really necessary?

Toriyama said once he likes to introduce characters in duos so they can bounce off of each other. So Puar exists for Yamcha to have someone to talk to.

"H-hey! Ouchh! That's kinda harsh, guys.." - Yamcha

Why did Chaozu exist too? They both seemed like they were there just to keep both Tenshinhan and Yamcha companionship and nothing else.
