Poochyena is a quadrupedal Pokémon similar in appearance to hyenas and canines. Its body is primarily gray with a black face and throat, paws, and belly. Its eyes are red with yellow sclerae, and it has a red nose. Its lower jaw has two pointed teeth sticking out. The fur at the base of its tail is rumpled and shaggy. Poochyena has gray paw pads on its three-toed paws.
Poochyena has a very keen sense of smell, allowing it to find and chase its prey with ease. It takes a bite at anything that moves and makes the hair on its tail bristle out to try to intimidate its foes. Known for its tenacious nature, it chases after prey until the victim becomes exhausted. If its prey strikes back, it may turn tail. It is omnivorous and will eat anything. This Pokémon lives in grasslands, savannas, and forests.

A Poochyena nicknamed Nana is first seen in Ruby's possession, one of the three Pokémon given to him from his father, Norman, when he was very young. Even five years before Creeping Past Cacnea, Nana was shown to be a formidable battler, injuring a Salamence teaming up with Kiki and Rara. While she still hadn't evolved, Ruby saw a few wild Mightyena that attacked Birch and envied how splendid their fur looked. A few chapters down the line, Ruby would obtain his own Mightyena in Dewford Town when he met up with Steven, and Nana evolved together with Kiki, who touched the champion's Moon Stone. This new evolved form saw a furthering of Nana's abilities, allowing her to perfect her Hyper Beam attack.
