Yes. When you go to Saffron City, go to the gym next to the official gym. That is the fighing dojo. If you beat everyone, you will get a chance to pick Hitmonchan or Hitmonlee. When you get it, beat the rest of the storyline. At Four Island postgame, there is a Daycare that can raise Pokemon. Drop off the Hitmon you chose with a Ditto and get a Tyrogue from the egg. Evolve Tyrogue to desired Hitmon.
