It is not known to evolve into or from any other Pokémon.
Hawlucha is a small, bipedal bird-like Pokémon. It has red, cape-like wings that are connected to its tail with green undersides and small clawed hands. It has red chest feathers, a white abdominal area and legs with small yellow feet. It has a green, mask-like face with an orange stripe down the middle, as well as orange rings around its eyes. Hawlucha has a small, red beak, and a white patch underneath it. It also has three orange tassle-like appendages jutting out of the back of its head. Its eyes have black sclera and large yellow irises.
Hawlucha makes up for its small body with its proficiency in fighting, which allows it to keep up with bigger fighters such as Machamp and Hariyama. It deftly controls its position in the air by using its wings. A favored tactic is to strike from above, as many opponents have a hard time defending against this maneuver. However, Hawlucha has a tendency to show off in the heat of battle; opponents can exploit its vanity to gain the upper hand.
Hawlucha debuted in The Forest Champion!. Prior to his capture by Ash, Hawlucha was the champion of a forest. Later, Ash challenged Hawlucha to battle with the condition that if he wins, Hawlucha will join his team. Although Hawlucha didn't lose the battle, he decided to join Ash's team.
