Magneton

 is a dual-type Type/ Type Pokémon.

It evolves from Magnemite starting at level 30 and evolves into Magnezone when exposed to a Coronet Rock.

Biology
Magneton is a robot-like Pokémon, the result of three Magnemite becoming linked together by a strong magnetic force, although a single Magnemite can evolve by itself when no other Magnemite are in the vicinity. Each individual Magnemite has a gray spherical body with a single eye, a gray and red-and-blue tipped horseshoe magnet on each side. The topmost Magnemite has three Phillips head screws on its body, while the others appear to have only two. The three Magnemite that Magneton consists of can be linked in several ways. Magneton is most commonly seen as one Magnemite on top, and two Magnemite linked by the screws on the bottom, forming a triangle. In some cases, commonly seen in 3D games such as Pokémon Snap, the Magnemite will not be connected at all, remain in a triangular formation at rest, and are able to freely move within each other's vicinity to form other patterns. In this case, all three Magnemite have three screws. The magnetic forces that hold the three Magnemite together are powerful enough to dry up all moisture and raise the temperature 3.6°F (2°C) within a 3,300 foot (1,000 meter) radius. It can also be disruptive to electronic devices. It uses powerful radio waves to help it study the surrounding area.

Being composed of three Magnemite, it is about three times as powerful electrically, though not three times as intelligent. Even though Magneton is a mechanical creature, it still has the need to eat. As seen in the anime, food for Magneton consists of electrical currents. It is usually found in rough terrain, often near power plants. When sunspots flare up, Magneton tends to appear more often, presumably due to the changes in the sun's magnetic field. When rain clouds form, it also gathers in high areas prone to lightning strikes. As seen in the manga, it possesses the ability to form its electricity into both platforms and barriers. Despite its modern, artificial appearance, carvings depicting Magneton have been discovered at the Ruins of Alph, and one was shown in a flashback to the great war of Kalos, indicating it has existed for at least 3000 years.
