Generation V introduced the most steel-types out of any generation, the Klink line being three of the twelve released in the Pokemon Black and White games. As of the newest games, the Klink and its evolutionary relatives are the only pure steel types related through evolution (they are also three of the five pure steel types to ever be released) which makes them quite a unique bunch of gears.
Klink is made up of a couple of gears that are a bit out of sort. They both have right eyes, and crosses for their left ones. They also have teal colored, clown-like noses. The gear part of their bodies is a light grey, while their faces are a darker, graphite color. According to their pokedex entries, the two minigears that mesh together are predetermined. Each will rebound from other minigears without meshing. Interlocking two bodies and spinning around generates the energy they need to live. Klink’s shiny sprite appears to be made of copper and their noses are green, like copper turns when it oxidizes. Klink’s name seems to come from the word ‘clink’, a sound that metal makes. There’s a possibility that the word ‘link’ may also be in its name, which may be a reference to the connection between the two minigears.
Once Klink reaches level 38, it evolves into Klang. While its right minigear appears to be the same, its left has grown an attachment. What was its entire face is now only its nose (which is now the same shade of its former nose), the larger gear being the rest of its face. Its pokedex entries state that by changing the direction in which it rotates, it communicates its feelings to others. When angry, it rotates faster. Spinning minigears are rotated at high speeds and repeatedly fired away. It is dangerous if the gears don’t return. Klang is based off from interlocking gears, in this case the sun and planet gears. Its name comes from the word ‘clang’, a sound that metal makes.
And finally, after it reaches level 49, Klang evolves into Klinklang. Klinklang is made up of two gears that are like Klang, though have an added, spiked ring surrounding it. The left side of it appears to be sticking its tongue out. According to its pokedex entries, Klinklang’s red core functions as an energy tank. It fires the charged energy through its spikes into an area. The gear with the red core is rotated at high speed for a rapid energy charge. Like its pre-evolution, Klinklang is based on interlocking gears, in this instance it seems to be based off from a combination of sun and planet gears, an external gear, and a bevel gear. Klinklang and its evolutionary relatives are the only non-electric-type Pokemon able to learn Thunder Shock. It is also the same height as its pre-evolution, Klang. Klinklang’s name is a combination of the words ‘clink’ and ‘clang’, the names of both its pre-evolutions.
