Aggron are huge, black and gray-silver, monstrous bipedal Pokémon. They stand on their hind legs and may use their arms to attack opponents and pick things up. They have a thick, long, black tail that they can swing at enemies and they have large armor plating on their body and head. They have three claws on each hand and on each foot. Their face and head is covered in gray-silver armor, with the uppermost, pointed plate possessing two pairs of holes on its upper section, with horns protruding from the foremost holes. These horns, which it uses to dig tunnels through bedrock when seeking food, grow a little longer at a time and can be used to determine the individual Aggron’s age. Aggron’s forehead plating extends past their upper jaws in a small point. Like its pre-evolutions, Aggron has sky-blue eyes, and a nostril-like hole 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 gray-silver-colored armor sections. Aggron have pointed black bands on their shoulders, and gray-silver bands on their arms and legs. Aggron that have gained gouges from previous battles apparently wear them as mementos, and it is suggested that the wounds do not heal, or do not heal rapidly, as Aggron's Black 2 and White 2 Pokédex entry states that the more wounds it has the more battles it has fought. If the wounds healed quickly or at all, they would not be visible to record these battles for the prolonged time the Pokédex implies. However, the Pokédex may be hinting that Aggron constantly battle and get many wounds in a short period of time, although the former seems more plausible.
Aggron evolves from Lairon starting at level 54.
You can tell its age by the length of its iron horns. It claims an entire mountain as its territory.
