"Hitmonchan is said to possess the spirit of a boxer who had been working toward a world championship. This Pokémon has an indomitable spirit and will never give up in the face of adversity."
Whereas Hitmonlee was the kicker, Hitmonchan is the puncher, said to be inspired by Jackie Chan, Hitmonchan is a favorite Pokemon from Gen I, and it's not hard to see why. Don't let the fact that this Pokemon has boxing gloves on fool you, he can punch so hard, it's like he doesn't have gloves on.
Hitmonchan's Basic Attacks are Bullet Punch and Rock Smash. Whereas its Special Attacks are Brick Break and Fire Punch.
