Metagross

Metagross  is a Psychic/Steel-type Pokémon that was introduced in Generation III. It evolves from Metang starting at level 45 and also is the final form of Beldum. It is one of the Pokémon that can be released from a Poké Ball in Super Smash Flash 2.

Pokémon description
Metagross has the appearance of an arachnid, thanks to its disc-shaped body and four legs. Along with those, its body has black and red eyes and a metallic cross that is situated in the center of its face, showing that your main body serves as both head and body. Its four legs are joined to the main body by ball-and-socket joints and they have short claws on the end and a flat, blunt protrusion extending over the knee. Also, while the upper portion of the legs is relatively thin, they are considerably thicker below the knee. Metagross legs can be tucked in, allowing it to float in the air.

In Super Smash Flash 2
As stated above, Metagross can be released from a Poké Ball as is somewhat uncommon. Once it is released, Metagross will use Earthquake, that, when in contact, will bury the opponents after slamming the ground. In case of being hit again, the opponent will suffer a considerable damage and may be thrown off the map.
