 Trophy description
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, as it's still an Electric and Steel type. It learns Magnet Rise, a technique that temporarily nullifies Ground-type attacks, a traditional weakness.
