Puar is very close and is extremely loyal to Yamcha, often following his orders without question or hesitation. Whenever Yamcha gets hurt or dies, Puar is the first to show concern, thus proving that he cares deeply for best friend's well-being. Aside from loyalty, Puar holds unwavering faith in Yamcha; examples include during the Universe 6 vs Universe 7 baseball match, Puar told Android 18 that Yamcha was perfectly suitable as the team's captain; another was during the Universe Survival Saga, Puar was happy when it appears that Yamcha has finally got an invite to join Goku and the others in the Tournament of Power.

In the anime-only part of the Vegeta Saga when a baseball riot ensues between the players, Puar tells Yamcha not to get involved (knowing full well of the latter's strength), showing that he has concern for the well-being of others.

He used to be bullied by Oolong during their time in Southern Transformation Kindergarten, and sometimes get annoyed by his perverted personality. In The Return of Son Goku and Friends!, Puar (along with Oolong, Chi-Chi, Bulma, and Piccolo) would become annoyed at Gotenks' recklessness.
