Instead of blood, a powerful magnetic force courses throughout BELDUM’s body. This POKéMON communicates with others by sending controlled pulses of magnetism.

About Beldum

95.2 kg for a creature barely 0.6 m tall: Beldum is a compact metallic mass that floats thanks to the magnetism generated by its own body. Each cell acts as a magnet and, instead of blood, a magnetic force capable of repelling gravity flows through its veins. It also uses those impulses to communicate. When several gather, they move in unison, as if they shared the same signal.

Its appearance is reminiscent of a robot reduced to a single part: a blue body, a red eye and rear hooks that it uses to anchor itself to cliffs while it sleeps. Pokédex entries also describe more aggressive behaviour: it attracts rivals with magnetism and attacks them with the claws on its rear.

The design is based on a dumbbell, an idea reflected in the Japanese name ダンバル and in the English name Beldum, both related to “dumbbell”. It is the first link in its evolutionary line: at level 20 it becomes Metang, and later reaches its final form, Metagross, at level 45.

Beldum in depth

A thinking dumbbell

Beldum’s design is based on a dumbbell, not on any particular animal. The rounded shape of its body, its high weight for its size and the absence of front limbs transfer that idea to a mechanical creature. The central eye and rear hooks complete the concept: it does not need legs to move because its magnetism allows it to float and attract or repel objects.

The name follows the same line. The Japanese ダンバル comes from “dumbbell”, while Beldum keeps that reference in English in an abbreviated form. The evolution reinforces the design: Beldum looks like an isolated part of a larger machine, Metang adopts a more balanced structure and Metagross brings four units together in a much more complex form.

Communication through magnetism

Pokédex entries present a species that does not use magnetism solely as an attack. It also uses it to communicate and coordinate. When it moves in a group, all its members move in unison. This behaviour fits its appearance as an organism built from connected components, even though each individual retains its own will.

Sleeping while attached to a cliff prevents the force keeping it afloat from carrying it away from the ground. It is a small detail, but it explains how a creature that repels gravity can rest without being at the mercy of the wind. The image of Beldum clinging to a rock face also supports its association with rugged terrain.

From a post-League gift to recent releases

In Ruby, Sapphire and Emerald, Beldum was obtained as a gift from Steven after entering the Hall of Fame. It was not an ordinary encounter: it arrived tied to the character who represents a specialisation in Steel and battles with Metagross. That origin made the species one of the most memorable parts of Hoenn, although its catch rate also meant that many players preferred to breed specimens from one they had obtained.

Its movepool has changed over time. For several generations, Take Down was the only move it learned by level. In later releases, it was replaced by Tackle, although Take Down remained available through other means. Its current movepool retains the same limitation: it barely learns any moves by level and relies on TMs to obtain Iron Head, Zen Headbutt or Iron Defense.

How to use it before it evolves

In a standard playthrough, Beldum works best as an evolution project rather than a permanent team member. Before level 20, it is worth keeping it safe from Fire, Ground, Ghost and Dark opponents, and looking for battles where its Defense lets it survive a physical hit. Clear Body prevents its stats from being lowered, but it does nothing about its 30 Speed or lack of coverage.

If it is used in lower-power battles, Iron Head and Zen Headbutt form the core of its offensive set. Iron Defense lets it take advantage of turns against opponents that cannot deal much damage to it, although the lack of recovery eventually takes its toll. Its role is to switch into attacks it resists, hit once or twice and leave before a Fire- or Ground-type user appears. Every level gained brings the species closer to Metang, which already offers a more complete presence in battle.
