In order to obtain Metagross, you'll have to complete the storyline and then head to Wintown. There, talk to Elita and she'll have a mission for you: you'll have to go to the Go-Rock Squad's hideout in the mountains. If you haven't done this already, you'll need two Pokemon with the cross ability - there are Tangela in the area. Go up the mountain and head in the direction of the Fiore Temple. In the area before that, you'll be able to go left after you climb up the steps with the falling Golem. Go across the waterfall with your two Tangela, and follow that path. Make it through the base, and it will explode.
If you've already done that, then go back to the Go-Rock Squad's base, which should be destroyed. Make your way through it - don't worry about getting lost, there's only one path you can follow. At the very end, you'll find Metagross and two Beldum.
You cannot catch a Metang in Pokemon Diamond. To get one, you can evolve a Beldum.
You can't catch Metang in emerald. You can only get Beldum, and then you can evolve it into Metang.
Just be paitent and catch it with a pokeball!
Metang evolves into Metagross at level 45.
you cannot! only beldum. after beating stewen go to his haus. take pokeball.
Catch a Beldum in Poekmno R/S/E. Evolve it and migrate it to Pearl. Or migrate it then evolve it.
Yes, it is worth the catch. Beldum = Metang = Metagross = awesome. But it is almost impossible to catch and if you do want one than it is near the battle frontier and the other one above it.
you can't catch metang in Pokemon, but you can catch the devolution, beldum by talking to dawn's sister in Sandgem town (you have to beat the elite 4 and champion first) there is only 1 Pokemon per day so do it daily or ask her and if it's not it change the time on your ds to 11:59pm wait 1 min and then ask again
In Pokémon Mystery Dungeon: Red Rescue Team, Beldum will evolve starting at Level 20 and it will evolve into Metang however it will only evolve once you take it to the Luminous Cave once it meets the conditions.
Beldum evolves into Metang at Level 25, and Metang evolves into Metagross at level 40. Level up Metang to Level 40.
go to the forest in the middle of giant chasm and 1:run around until you find metang(it has a 10% catch rate)catch it and evolve it or 2:look in rustling grass
Metang evolves from a Beldum at Level 20. Metang evolves into a Metagross at Level 45
