Where can you catch a fighting type Pokemon

I bet you know, it's probably not serious isn't it?
but well okay, you can catch them in diamond and pearl right above oreburgh(machop if that's what you mean) , in black and white close to pinwheel forest, in emerald, ruby and sapphire almost everywhere but for example makuhita in granite cave and shroomish who evolves into the fighting type breloom in petalburg woods. Gold, silver and crystal; bit more difficult but still easily to catch underneath goldenrod. last but not least leaf green, blue and fire red; route 4 by suggestion or for the tough deal you'll get one in the saffron dojo.

if you still don't get it you better search on bulbapedia or serebii
