You will a have to evolve a beldum which is given by Steven at his house after beating the elite four.
You cannot find a wild Metang, you can only evolve it from a Beldum, which you can obtain from Steven's house in Mossdeep City.
you can't find metang in Pokemon diamond you have to get beldum in swarm when you get the national pokedex and then evolve it
You will have to evolve a metang.
Metang is a Steel and Psychic type pokemon.
There is no Pokemon mansion in sapphire.
He is not in Pokemon: Sapphire. You will not be able to find him. He is in Pokemon: Diamond, Pokemon: Pearl, and Pokemon: Platinum. You will definitely have trouble finding him in Pokemon: Sapphire.
you can't find it in Pokemon sapphire, but you can find it in Pokemon ruby. Hope this helped. :-)

You cannot catch a Metang in Pokemon Diamond. To get one, you can evolve a Beldum.
Lucario isn't in Sapphire,Sapphire is a Hoenn pokemon,Lucario is a sinnoh pokemon.
Metang evolves into Metagross starting at level 45. (Beldum evolves into Metang starting at level 20.) Metang is #375 in the National Pokedex, and was introduced in the Generation III Pokemon titles (Ruby, Sapphire, and Emerald) where Beldum could be found in Steven's house in Mossdeep City, and then evolved into Metang. In Generation VI (X and Y), it can be found in some Steel type Friend Safaris.
beldum metang and metagross are not in the game :(
