Smeargle is uniquely associated with the move Sketch as its signature move.
Sketch allows Smeargle to permanently copy the last move used by a target, giving it an unusually broad potential move list. Unlike most Pokémon, Smeargle can use Sketch repeatedly as it levels, replacing earlier copied moves with new ones. This makes it a distinctive choice for specialized teams and battle experimentation.
Smeargle is a Normal-type Pokémon introduced in Generation II. Its design resembles a beagle or other painting dog, and the paint-like fluid on its tail is central to its visual theme. Its name combines “smear” with “beagle,” reflecting the painting concept and canine appearance.
Smeargle does not evolve, and its unusual move mechanics distinguish it from Ditto. Ditto can transform into an opponent, but it does not learn and retain moves through Sketch. The move's availability and exact mechanics have changed across game generations, but Smeargle remains its defining user.
