Klinklang resembles four interlocking gears, with six teeth on the smaller two gears and eight teeth on the larger gear. The fourth gear is on its lower side, and is red-topped with a thin, spiked rim below it. The red core is used to store energy gained from the rotating gears. This energy can be released through the spiked gear at the bottom. The teeth of the smaller gears are a light gray, while their central regions are much darker. The teeth of the larger gear are a medium gray and its central region is darker. The left eye of the smaller gear is a white "X", while its right eye has a black pupil and a white sclera. It has a round green nose and a small mouth. The largest gear appears to have a face with a black square for its left eye, a black circle for its right eye, and a sharply angled white frown. Dialogue between the two faced gears in the Pokémon Mystery Dungeon series suggests that both gears are independently sentient from one another. Klinklang can fire tiny gears at high speeds in the form of Gear Grind and Shift Gear, its signature moves.
Klinklang debuted in White—Victini and Zekrom and Black—Victini and Reshiram alongside Klink and Klang; they are all under the ownership of Mannes. He used the three for various tasks, such as powering the music machine at Eindoak Town's Harvest Festival, doing yard work on his property, and powering his helicopter in the climax of the films.
NA:This Pokémon evolves in the following order: Klink, Klang, and finally Klinklang. I wonder what it would be called if it evolved again... Klinklangklung? The noise from that Pokémon would be unbearable! Anyway, Klinklang's small, red center gear will spin at high speeds when it's charging up energy.
PAL:From Kling to Klang to Klinklang, this Pokémon gets noisier with each evolution! It has a nice ring to it, though. Maybe all Pokémon should be named this way! Abra, Kadabra, Abrakadabra? Gible, Gabite...Gigabite? Err...Moving on! When it charges up energy, Klinklang spins the small cog with the red core at very high speeds.
This Pokémon was unavailable prior to Generation V.
Klinklang is a combination of Klink and Klang, making it also a combination of clink and clang (onomatopoeia for metal striking a surface). It may also involve link, possibly referring to how the four gears are connected.
Gigigiaru is derived from gear, with gi repeated twice to denote the addition of Klang's fourth gear.
