Beldum is a robotic lifeform that has a long body with a set of claws sticking out of its rear end. It has one large red eye in the centre of its nearly-round head, which is set into a ball-and-socket joint at its front end. It has a short crest above its head, projecting from its body. Even though Beldum and its evolved forms are mechanical creatures, they still have emotions, the need to eat and a way of reproducing. Beldum has been said to be related to Magnemite due to the fact that both of them are partially Steel-type, 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.
