Metagross can only learn Earthquake with the use of a TM.
Metagross learns Hammer Arm on level 45.
on level 53
at level 62
It can learn it via the TM but not by level.
Depends on the version you're playing. Considering you're playing ruby, sapphire and emerald(cos its under that catergory), metagross should learn meteor mash at level 55.
To get Metagross, make sure you have a Beldum. Then raise it so it can evolve into Metang. Then evolve it at level 45 but I rather make it evolve at level 50 because Metang can learn the move Meteor Mash then let it evolve into Metagross.
level 595,584,395,492,000 Don't give bad answers like that. It's level 55.
In Pokemon Pearl, Diamond, HeartGold, and SoulSilver, Metagross can learn Stealth Rock by using TM76 on it.Since TM76 is no longer Stealth Rock in Black and White, if you want a Metagross that knows it in those games, you must use the TM in one of the earlier games and trade it to Black or White.
Umm...hard to break it to you but.....metagross can only learn Earthquake if you teach it the TM. Sorry =(
Train a Beldum to level 33 then train Metang to level 50 to get Metagross.
If you are asking what level a Metang evolves into a Metagross, it is level 45.
