Aron (Japanese: ココドラ Kokodora) is a Steel/Rock-type Pokémon introduced in Generation III.

Biology

Physiology

Aron is a small quadruped Pokémon with four chubby legs and a large head, more than half the size of its body. Its body is black in color with gray plates of armor covering most of its body parts.

Its eyes are a pale shade of turquoise. There are several openings on its armor, and a blunt spike extends from its back.

Natural Abilities

It can destroy a heavy truck with a full-speed charge.

Behavior

To make its body, Aron digs out iron from the mountains for food. Sometimes hunger motivates Aron to go downhill to eat the railways and bridges, which may cause some big problems and is seen as a vermin.

Evolution

Aron evolves into Lairon once level 32 is reached. Then it evolves into Aggron at level 42. It can evolve into Mega Aggron using the Aggronite.
