Aggron is the final evolutionary form of Aron. It evolves from Lairon. It is a dual Rock/Steel type. However, when it Mega Evolves, it becomes a Pure Steel type.
Its name may be a combination of aggressive or aggregate, as in aggregate metals, and iron.
Aggron claims an entire mountain as its own territory. It mercilessly beats up anything that violates its environment. This Pokémon vigilantly patrols its territory at all times.
Aggron is so protective of its environment, that if its mountain is ravaged by a landslide or a fire, this Pokémon will haul topsoil to the area, plant trees, and beautifully restore its own territory.
