Beldum

Beldum, known in Japan as Dumbber, is a Steel/Psychic-type Pokémon introduced in Generation III. It evolves into Metang at level 20 and once more into Metagross at level 45. In Super Smash Flash 2, it appears in the background of Pokémon Colosseum's Steel-type transformation.

Pokémon description
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 a mechanical creature, it still has emotions, the need to eat, and a way of reproducing. Beldum's body lacks blood, and is instead powered by a magnetic force.

In Super Smash Flash 2
Beldum appears in the Steel transformation of the stage, Pokémon Colosseum. It has no effect on the players whatsoever, and simply floats in the background, watching the match.
