Magnezone is a robot-like Pokémon which resembles a UFO. It's the result of Magneton leveling up in the presence of a special magnetic field. The evolution is done on a molecular level, but despite this, scientists have failed at attempts to force it. Magnezone's body is wide and circular, similar to a disc or saucer, with a thin edge circling the diameter of its body. Its main eye is in the center, containing a large, red pupil. On each side of its body, it has a ball-shaped addition, with each side containing an eye, horseshoe magnet, and Phillips head screw. These secondary eyes can move independently of its main eye, as shown in Confronting the Darkness!. On top of its head is a tall, thin, yellow rod, closely resembling an antenna, which it uses for certain attacks. Behind its body is a third horseshoe magnet, positioned like a tail.
Magnezone's evolution is theorized to have been caused by a special magnetic field that changed the molecular structure within its body. Magnezone is a seemingly-mechanical, gender unknown creature, but it has emotions, a way of reproducing, and the need for nourishment. With its magnets, it has the ability to control anti-gravity and float through the air at will. As seen in Giratina and the Sky Warrior and Phantom Thief Pokémon 7, Magnezone's anti-gravity is strong enough to carry humans with ease. Magnezone is rarely seen in the wild, but as seen in the anime, Magnezone can be very aggressive and territorial. However, it will rarely attack unless provoked. It flies through the night sky, often mistaken for a UFO sighting, though it seems to be receiving and sending signals from an unknown source and an unknown purpose. This leads some people to believe that Magnezone came from outer space and that it is being controlled by unknown beings.
Magnezone debuted in Giratina and the Sky Warrior, under the ownership of Zero. Despite Zero's maniacal behavior, Magnezone was very loyal to him. Magnezone generally acted as a leader to Zero's army of Magnemite and Magneton.
A wild Magnezone appeared in Regaining the Home Advantage!, which also served as the species' main series debut; it battled nonstop with a Metagross. These two Pokémon normally battled with each other on a regular basis until their "battle arena", a deep crater, was filled up with water. Because their crater was no longer usable, they took their battle to the streets of a nearby town, and continued fighting, causing much collateral damage.
Magnezone was used by a Team Galactic Grunt that attacked Hiori and Rocco when they attempted to fly to the Team Galactic section base. It had an aerial fight with Hiori's Drifblim, but despite the type advantage, Magnezone and the Team Galactic Grunt were defeated by Hiori's quick thinking.
Magnezone appears on the Electric terrain of Pokémon Stadium 2.
"A Magnet Area Pokémon. It's a Magneton that evolved in a special magnetic field at Mt. Coronet. Its appearance is quite different after it evolves, but it still has three round eyes. Its shape changes but not its type--it's still both an Electric and Steel type. It learns Magnet Rise, a technique that temporarily nullifies Ground-type attacks, a traditional weakness."
Despite most depictions of Magnezone showing they are able to float through the air, Magnezone does not have the Ability Levitate, so it is still affected by Ground-type moves. However, Magnezone can learn Magnet Rise, which simulates Levitate for five turns.
Magnezone (along with Probopass, Leafeon, and Glaceon) is one of four Pokémon in Pokémon GO that must be evolved while the player is within range of a Pokestop outfitted with a Lure Module (in this case, a Magnetic Lure Module)
Magnezone appears to be based on the concept of a fused Magneton; one of the Magnemite taking a larger form and the remaining two Magnemite taking the forms of the smaller bodies on each side. The Magnemite evolution line seem to be based on the objectification of electromagnetism, one of the four fundamental interactions of nature. Magnezone in particular is possibly based on electromagnetic forming caused by electromagnetic fields and combined with an objectification in the form of a flying saucer or a UFO.
Magnezone may be derived from magnetic zone, an alternative name for a magnetic field.
