Aggron (Japanese: ボスゴドラ Bossgodora) is a dual-type Steel/Rock Pokémon.

It evolves from Lairon starting at level 42. It is the final form of Aron. It can Mega Evolve into Mega Aggron using the Aggronite.

Biology

Aggron is a huge, bipedal Pokémon. It is primarily black with plates of silver-colored armor. The armor 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 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 armor sections. It has wide, blunt spikes on its shoulders, and gray-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.

Mega Aggron is bulkier and more heavily plated than its previous state. The horns on its forehead are now shorter, and it has a third, wider horn on its nose. Using its horns, it is said to be able to destroy a steel tank into scrap metal. A spike projects downward from both its upper and lower jaw. The protrusions on its shoulders are longer and curve toward its head, and new spikes thrust from holes in its armbands. Its tail is thicker with two bands around it.

The gouges in Aggron's armor 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.

Trivia

  • As it is the heaviest Pokémon that can learn it and gets STAB from it, Heavy Slam is most potent with Aggron.
• Aggron is the only dual-typed Pokémon to become a single-typed Pokémon upon Mega Evolution.
• Aggron and it's evolutionary line (excluding Mega

Aggron) that has a double weakness to fighting moves

• Mega Aggron is tied with Shuckle for the highest base Defense stat of all Pokémon.

Origin

Based on the fact that it eats the iron, it may draw inspiration from Pulgasari, a monster which eats iron in Korean legend. It may also be based on a Triceratops and various therapods.

Name origin

Aggron may be a combination of aggressive, iron, and don. It may also involve aggro (British slang for aggression).

Bossgodora may be a combination of boss and dragon, or may be a combination of boss and Kodora (Lairon's Japanese name). It may also involve god.
