Magneton is the result of three Magnemite being linked together by a strong magnetic force, although a single Magnemite can evolve by itself when no other Magnemite are in the vicinity. The three Magnemite that Magneton consists of can be linked several ways. Magneton is most commonly seen as one Magnemite on top, and two Magnemite linked via body on the bottom, forming a triangle. However, in some cases, the Magnemite will not be connected at all, but remain in a triangular pattern. In the anime, the size of Magneton's magnets change in different episodes. This does not seem to be based on anything except possibly an oversight by the animators. Even though Magneton, its pre-evolution and its evolution are all mechanical creatures, they still have emotions, can get hungry, and have a way of reproducing.
Magneton is a genderless species.
Magneton can emit strange radio waves that can greatly damage various electronic equipment, raise air temperatures by 3.6 degrees Fahrenheit (2 degrees Celsius) within a 3,300-foot (1,000 meter) radius, and cause earaches for anyone that gets too close to it. Magneton mostly learns attacks that Magnemite is capable of learning. Magneton and its evolutionary chain are the only Electric-type Pokémon to learn Zap Cannon. Unlike Magnemite, Magneton can learn Tri Attack and it is one of a small number of Pokémon still capable of evolution that are able to use Hyper Beam and Giga Impact.
Magneton behave similarly to their pre-evolution, Magnemite, in that they generally do not bother people and keep to themselves unless provoked. If they are provoked however, they will resort to non-damaging moves, but, will not hesitate to use more powerful moves if not left alone. Unlike most other evolved Pokémon, in battle, Magneton are very easy to command and rarely lose focus.
When sunspots flare up, Magneton tend to appear more often in the open, presumably due to the changes in the sun's magnetic field.
Magneton usually live around power plants and rough terrain where large deposits of metal can be found, but they're harder to find than Magnemite. They're found in Kanto and Johto. Despite their modern, artificial appearance, carvings depicting Magnemite and Magneton have been discovered at the Ruins of Alph, indicating they have existed for at least 1,500 years.
Magneton feed off electrical charges.
