Aggron

Aggron is a huge, bipedal Pokémon. It primarily has a crusty grey exoskeleton, with plates of silver armour adorned. The armour on its head has two pairs of holes with horns protruding from the foremost holes. Its forehead plating extends past its upper jaw in a small point. It has sky-blue eyes, and two nostril-like holes on the tip of its upper jaw. On the rim of its mouth are several pointed, fang-like protrusions and the nape of its neck and back have grey-silver armour sections. It has wide, blunt spikes on its shoulders and grey-silver bands on its arms and legs. Its hands and feet each have three claws. It has a thick, long, black tail that it can swing at enemies.

The gouges in Aggron's armour from previous battles are worn as mementos. The more wounds it has, the more it has battled. It claims a large mountain as its territory and fiercely defends it from trespassers. If its environment is damaged by a flood or a forest fire, it will restore the area by bringing in topsoil and planting trees. It burrows through the strongest of bedrock and digs tunnels, as it searches for iron to eat. Its horns, which it uses to dig through bedrock when seeking food, grow a little longer at a time and can be used to determine its age. Aggron's horn is sharp enough to cut through steel and used as a ramming weapon to bring foes down. Long ago, there was a king who wore a helmet resembling an Aggron in an attempt to channel its strength.
