How do you catch Tyrogue on FireRed?

You can't catch Tyrogue in FireRed. It's exclusive to Gold, Silver, and Crystal.

To obtain Hitmontop, Hitmonlee, and Hitmonchan, you can use the following methods:

* Hitmontop: Trade a Tyrogue with an Attack stat equal to its Defense stat to a Trainer in Gold, Silver, or Crystal. They will give you Hitmontop in return.

* Hitmonlee: Trade a Tyrogue with a higher Attack stat than its Defense stat to a Trainer in Gold, Silver, or Crystal. They will give you Hitmonlee in return.

* Hitmonchan: Trade a Tyrogue with a higher Defense stat than its Attack stat to a Trainer in Gold, Silver, or Crystal. They will give you Hitmonchan in return.

If you have access to the Virtual Console versions of Gold, Silver, or Crystal, you can transfer a Tyrogue to FireRed using the Poke Transporter. This would allow you to evolve it into Hitmontop, Hitmonlee, or Hitmonchan in FireRed.
