Evolve Feebas
You can't find Registeel in Pokemon Platnium. You just migrate it in Pokemon Ruby, Pokemon Sapphire, and Pokemon Emerald.
In the sinnoh dex it is feebas you can see it on route 222. A sailor has it.
There is no 'platnium', but you can find it on wild pokemon.
you cant catch it in platnium but you can trade it
you will find feebas in the water of grass maps in pokemon vortex
the most wanted in this houshold is Pokemon platnium
you must trade a machoke to another ds and it will evolve into a machamp.
