Klinklang has changed significantly from its previous evolved forms. With a large spiked metal plate on the bottom held by a medium-sized gear, it has a large gear in the back and a small gear in the upper left area and another one near the center.
Klinklang and its pre-evolutions are the second, third and fourth Pokémon to have the ability Plus, with Plusle as the first, and are also the second, third and fourth ones with the ability Minus, with the first as Minun.
Klinklang is the only Pokémon which is used twice by N; the first used in Chargestone Cave as a Klink, and used in the final battle against him as a Klinklang.
Klink, Klang and Klinklang's right gear stays the same as it evolves.
Klinklang is based on a large network of three rotating gears.
Klinklang's name is a combination of the names of its two pre-evolutions, both of which are named after metallic sounds (cling, and clang).
