Brawly's Pokémon are all fighting-types.
The author describes him: "Hariyama is entirely covered with well-trained muscles. It does not fear any enemy!"
Makuhita debuts in Chapter 193.
Brawly takes Makuhita surfing with him in order to teach him the Ju style of fighting. Makuhita has gathered plenty of energy within it, enough that upon command during Brawly's battle against Sapphire, Makuhita evolves into Hariyama. Despite this, Hariyama still loses.
Brawly later sends Machoke out to fight against Groudon.
Machoke is knocked out, but Brawly's Hariyama revives him with Smelling Salt. After being brought to Lilycove by Mack, Brawly uses Machoke against Mack's Slugma. Brawly and Machoke are tricked with illusions, and Machoke is terrified when a painting seems to come to life behind them, making Machoke run and panic.
