Steelix
You cannot get Steelix through a Pokémon breeder, you get it by trading a Onix holding a Metal Coat.
legendary pokemon.
you should add... kingdra
(Excluding legendary pokemon) It should be dragonite...
pokeballs... which should be at the mart..
nothin u dude
get an onix, then give it the item metal coat, and trade it to another game. it should evolve
you should have a lvl 50 water type
You cannot find it in Diamond; the only way to get a Scizor is to give a Syther a Steel Coat, trade it to another person, then trade it bak again. It should be able to evolve into Sizor.
Charizard is the best choice
You should definitely get Pokémon Emerald.
