Aggron is best described as a monster. It bears a dragon like appearance with iron plates over its entire body, horns, and claws; this Pokémon was built for battle. Some say that it looks partially like a castle wall.
Aggron evolves from Lairon at level 42, and is the final evolution of Aron.
Aggron plays an important role in Pokémon Conquest, as the Partner of Ieyasu, the Warload of Valora, with a +2 Iron Head.
