Pokémon description
Klink resembles two interlocking gears with six teeth each. The teeth of the gears are a light gray, with a darker central region. Each gear has a white "X" in place of its left eye, while their right eyes have a black pupil and white sclera. They have round turquoise noses and small mouths. Klink can launch itself at opponents in the form of Gear Grind and Shift Gear, its signature moves. Once two bodies have joined, they cannot combine with any others or they will become separated. Klink generates its life energy by spinning, and is generally found in caves. According to Professor Juniper, the first recorded evidence of this Pokémon dates to around 100 years ago, in the Chargestone Cave; she believes that it suddenly appeared in the cave at that time.

In Super Smash Flash 2
Klink is one of the Pokémon that can be released from a Poké Ball in Super Smash Flash 2. Once released, Klink will fly slowly towards one of the opponents and use Gear Grind once it's close enough. It repeatedly attacks opponents who make contact with it, but its attacks are weak and can easily be escaped from with proper directional influence.
