once you get a pokeradar (obtained after you fill in your pokedex by seeing all the Pokemon and then go to prof Rowan) go to the west of route 211 and use it in the grass. its hard to find though.
Tyrouge? Isn't that a Pokemon? If you are talking about the Pokemon, Tyrouge aren't that hard to find...
it isn't a trainer its a gym leader her name is maylene she is in veilstone city
Tyrouge is the preevolution of hitmonlee, hitmonchan and hitmonchan to get Tyrouge you need to breed one of those 3 Pokemon with ditto.
After getting the Pokemon radar, use it in route 211 (west). It's a fairly rare spawn, so keep trying.
In Pokemon diamond, pearl and platinum tyrogue himself cannot breed, however if you have a hitmontop, hitmonlee or hitmonchan you can get a tyrogue egg when bred with a ditto
its tyrouge and you find him in pueltown
Man in mount mortar gives you it. He is quite deep inside.
Tyrouge can be obtained by breeding either an Hitmonlee, Hitmonchan or Hitmontop. Put a Ditto and either Hitmon pokemon in the four island daycare then hatch the egg you will recieve this will give you Tyrouge.
It has to be a pokemon outbreak or use an action replay.
