Beldum is a robotic Pokémon that has a long body with a set of claws sticking out of its rear end. It has one large, red eye in the center of its nearly spherical head, which is set into a ball-and-socket joint at its front end. A short crest projects from its body and extends over its head.
Even though Beldum is mechanical, it still has emotions, the need to eat, and a way of reproducing. Beldum's body lacks blood, and is instead made of cells that are all magnets. It uses magnetism to move, communicate, and control its attacks. Beldum sometimes gathers in swarms, communicating with each other telepathically and magnetically and moving in sync. When enraged, it can cause nearby machines to break from its strong magnetism. Beldum can also use its magnetic force to rapidly pull in enemies and then use its sharp claws to harm them. Beldum is scarce in the wild, but it does tend to inhabit areas with rugged terrain. It anchors itself to a cliff using its hooks when it sleeps.
Instead of blood, a powerful magnetic force courses throughout Beldum's body. This Pokémon communicates with others by sending controlled pulses of magnetism.
Beldum keeps itself floating by generating a magnetic force that repels earth's natural magnetism. When it sleeps, this Pokémon anchors itself to a cliff using the hooks on its rear.

Beldum, the Iron Ball Pokémon. Beldum floats by emitting magnetic waves from its body to repel the Earth's magnetic field. They launch their claws into cliffs where they sleep.
Steven owns a large amount of Beldum that serve, along with a Metang and Metagross, as miners that help him unearth rare stones in various caves around Hoenn. They first appeared in Ring Ring Goes Beldum. These same Beldum were called upon to defeat the Mawile herd in Granite Cave when both Ruby and Steven were attacked by them. Four of Steven's Beldum later formed the party that would unseal the legendary giants, which included Sapphire's Lorry and Relly.
Beldum, along with its evolved forms, are the only non-Legendary Pokémon to have a catch rate of 3, which is the lowest in existence.
Beldum's evolutionary family evolves into their next-stage forms the earliest of all the pseudo-legendary Pokémon—Beldum into Metang at level 20, and Metang into Metagross at level 45.
Beldum is the only member of a pseudo-legendary Pokémon evolutionary line that only learns one move by level up.
Beldum and its evolutions all share both their standard and hidden Abilities with Registeel.
