What level does hitmochan learn his moves?

Hitmonchan doesn't learn moves by leveling up. It can learn moves in the following ways:

* TMs and HMs: Hitmonchan can learn moves from Technical Machines (TMs) and Hidden Machines (HMs). This is the primary way to teach it new moves.

* Breeding: Hitmonchan can inherit some moves from its parents, depending on what they know.

* Move Tutor: Certain moves can be taught to Hitmonchan through the Move Tutor, a feature found in some Pokémon games.

You'll need to check the specific Pokémon game you're playing to find out which moves Hitmonchan can learn and how.
