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.

Biology

Physiology

Aggron are huge, black and gray, 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. Their face and head is covered in gray 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-colored armor sections. Aggron have pointed black bands on their shoulders, and gray bands on their arms and legs.

Gender differences

None.

Special abilities

Like Steelix, Aggron's only real special ability is its incredible defense, but it does have an imposing 110 base Attack as well. Unlike other Template:Type2 Pokémon, Template:Type2 attacks are not super effective on Aggron because it is part Template:Type2. Aggron also has many Dragon-like characteristics, and it can learn Template:Type2 moves such as Dragon Claw.

Behavior

Aggron are very fierce and aggressive Pokémon. They are also incredibly strong. They claim entire mountains as their territory, patrolling it at all times and mercilessly beating up intruders. The gouges in its armor are apparently worn with pride as mementos from battles. If their environment is damaged by a flood or a forest fire, they will restore the area by bringing in topsoil and planting trees. Like many Pokémon (especially Kangaskhan), Aggron are very caring of their young and will defend them with their life.

Habitat

File:Mountain.gif

Mountain Pokémon

Aggron live in mountainous habitats and will claim an entire mountain as their territory. They also dig tunnels to live in by burrowing through bedrock with its steel horns.

Diet

Main article: Pokémon food

Much like their pre-evolutions, Aggron eat iron, especially those that have not rusted.

Trivia

• Despite being part Template:Type2, Aggron does not learn any Rock-type moves by leveling up. However, it learns Head Smash through breeding.
• Aggron can learn the signature moves of both Cranidos and Shieldon's evolutionary families: Head Smash and Metal Burst, the former by breeding, and the latter by leveling up.
• Aggron is commonly mistaken as a pseudo-legendary Pokémon, due to it being commonly seen as fearsome as a Tyranitar or something of the sort in the anime.
• With Heavy Metal, Aggron is the heaviest non-legendary Pokémon, and both the heaviest Steel-type Pokémon and Rock-type Pokémon.
  • As it is the heaviest Pokémon that can learn it, Heavy Slam is most potent with Aggron.

Origin

It may be based on a Triceratops and various therapods.

Name origin

Aggron's name is a combination of aggressive and iron.

Bossgodora may be a combination of the English words boss and dragon. It is more likely a combination of boss and a corruption of kodora, the Japanese name for Lairon, indicating that Aggron is a larger and meaner version of its pre-evolution. Bossgodora may also come from god.

In other languages

Language Name Name Origin German Stolloss From Stahl and Kolloss. French Galeking From gallet and king. Korean 보스로라 Bosslora Chinese (Taiwan) 波士可多拉 Bō Shì Kě Duō Lā Transliteration of its Japanese name.
