Klink is a small two-headed metallic Pokémon that resembles a set of gears. It slightly resembles Magnemite and Magneton, except it appears to consist of two spinning gears. Both gears are identical and have an X for the right eye. Each gear's other eye is open and round with a black pupil, and it has a greenish dome-shaped center that appears to be its nose and a round, open mouth.
Klink is currently the only Pokémon aside from one which has modified its natural ability to be able to power up a Plusle or Minun in battle, having the ability to have either Plus or Minus, previously exclusive to the two.
This Pokémon was revealed along with six other Pokémon in July's issue of CoroCoro on June 11, 2010, making one of the first regular Pokémon announced for the 5th Generation.
Klink and its family are currently the only pure Steel-type Pokémon related by evolution.
