Puar (プーアル, Pūaru) is a shapeshifting animal that is Yamcha's lifelong best friend. Along with Yamcha, he used to live at Bulma's place until they both get kicked out after Bulma suspected that Yamcha was cheating on her. In a TFS promo, it's revealed that she's in love with Yamcha. She is voiced by Megami33.
In Future Trunks' timeline, Yamcha committed suicide likely due to learning that Bulma had gotten with Vegeta of all people. A rather dark deleted scene for the already dark segment revealed that he used Puar as a shapeshifted rope, as the scene has Puar asking the dead bandit if she can transform back.
Despite only looking like a cat in the original manga and the anime (as stated by Akira Toriyama), in DBZ Abridged she IS a cat (and even has a litterbox).
