    Emerald

  9. AGGRON is surprisingly protective of its environment. 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.

    Sapphire

  10. 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.
