Hariyama is a large, bulky Pokémon that is modeled after a sumo wrestler. It has narrow eyes and rounded ears. On its head is a short, triangular crest. Dark blue hair grows across the tops of its eyes, around the head crest, and extends down its back to form a long ponytail. The upper half of its body is cream-colored, while the lower half is dark blue. Yellow extensions encircle its waist, resembling a skirt. There is a small, orange half-circle marking in the center of its torso just above the skirt. Hariyama has large hands with three fingers and small, two-toed feet. Both its hands and feet are orange.
Hariyama's body consists mostly of muscle instead of fat. When its body tenses, its muscles become as hard as stone. It likes to match power with other big-bodied Pokémon and can stomp the ground to build its own power. Trucks can be sent flying, telephone poles broken in two, and trains can even be stopped by its powerful slapping arms. They are kindhearted and practice etiquette, praising its battle opponents. As it grows older, it focuses more on training Makuhita. It is the only known Pokémon to know the move Smelling Salts. It lives in mountainous areas.
Hariyama, the Arm Thrust Pokémon. A Fighting type. Hariyama's impressive bulk is actually all muscle. When its muscles are flexed, they are hard as a rock. It is said that one hit from a Hariyama can send a 10-ton truck flying.
Hariyama appears in Mashing Makuhita as the evolved form of Brawly's signature Pokémon. Despite the new-found power that it got from evolving during its Gym battle with Sapphire, it was unable to defeat Chic. Hariyama is later used when Brawly is attacked by Blaise of Team Magma.
A Hariyama appears with its Trainer at the Mini-game Corner in PS553.
Hariyama has a higher catch rate than its pre-evolution.
Hariyama seems to be based on a sumo wrestler, also known as a rikishi or sumōtori. Its bald head and long hair resemble a chonmage (a traditional hairstyle for sumo wrestlers) before it's tied into a topknot. Its two-toed feet resemble geta or zōri (Japaense wooden sandals). The square flaps surrounding its midsection resemble sagari (stiff strings) that hang off a wrestler's mawashi (cloth belt). Its large hands, category, and ability to learn Arm Thrust may be a reference to harite (an open-hand strike), and its habit of stomping the ground in battle may be a reference to shiko (an exercise/ritual used to drive away spirits). Its ability to learn Brine and signature moveSmelling Salts may be a reference to the ritual of throwing salt before a match to purify the dohyō (wrestling ring), and ability to learn Whirlwind could be a reference to the god of thunder, Takemikazuchi, who is believed to have fought in the first recorded sumo wrestle.
Hariyama and Hariteyama may be a combination of 張り手 harite (an open-hand strike), 張り合う hariau (to compete with), 張り倒す haritaosu (to knock down), 針山 hariyama (pincushion; referring to its plump body), and 山 yama (mountain; referring to its large size).
