It evolves from Metang starting at level 45. It is the final form of Beldum It can Mega Evolve into Mega Metagross using the Metagrossite. Mega Metagross has the ability Tough Claws and all of its stats are increased.
Metang is a robotic lifeform that has a disc-shaped body with a pair of appendages that resemble Beldum. It has two red eyes and a pointy nose. Even though Metang and its evolved forms are mechanical creatures, they still have emotions, the need to eat and a way of reproducing. Metang has been said to be related to Magneton due to the fact that both of them are partially Steel-type that create electromagnetic waves to float in the air, and probably due to the fact that they evolve in a similar fashion, it takes two Beldum to evolve into a Metang and two Metang to evolve into a Metagross. When not levitating, it stands on its appendages, similar to its evolution. It may use its appendages like boosters to gain speed.
