Magneton

Magneton (レアコイル Rarecoil) is an /-type Pokémon. It is the evolved form of Magnemite. It evolves into Magnezone by leveling-up in Mt. Coronet in the Generation IV games and Chargestone Cave in the Generation V games.

Appearance
Magneton are simply three Magnemite linked together by magnetism.

Special Abilities
The abilities that Magneton can have are Sturdy or Magnet Pull. Sturdy prevents any OHKO moves from hitting Magneton. Magnet Pull prevents any -type Pokémon from escaping battle. Magneton is capable of producing powerful magnetic waves that can damage electronic devices, create ear-splitting headaches, and raise temperatures up to 3.6 degrees Fahrenheit within a 3,300 ft radius.

Magneton, along with its evolution family, is the only Electric Pokemon that can learn Zap Cannon via leveling up.

Anime
A Shiny Magneton appeared in the episode Tie on One.

In the episode Watt's with Wattson, a Magneton appears alongside with its pre-evolution Magnemite and a Voltorb, all three under the ownership of the Mauville Gym leader Wattson. It was used by Wattson to battle Ash, but was instantly defeated by Pikachu, because Pikachu's electric attacks were powered up from destroying a mechanical Raikou.

Trivia

 * Starting with the Johto Region, Magneton is one of only two Pokémon to have had their types changed, being as how Steel was introduced when Gold and Silver where released. The other is it's pre-evolved form, Magnemite.
 * Magneton, along with its pre-evolved and fully evolved forms, is the only Pokemon with a Electric/Steel type combination.
 * Despite in the anime it floats, it's ability isn't levitate nor its evolution line's.
 * The only move type that isn't affected by Magneton and it's evolutionary line's type is water, as all others are super-effective (eg. ground), not very effective (eg. flying) or don't affect (eg. poison).
