Len Town is an anime-exclusive location in Johto, more specifically located between Azalea Town and Goldenrod City. The town is surrounded by a forest that is densely inhabited by many -type Pokémon; as such, all residents of Len Town own a -type Pokémon to fend of -types, as the former has a type advantage while the latter doesn't, although this was only in Generation I; in Generation II, the generation Len Town was introduced in, -types deal an equal amount of damage to types as they do to them.
In the anime, Team Rocket built a Gengar-like machine that repelled all -type attacks, and Team Rocket used it to steal the townspeople's Pokémon; however, Ash and Co. stopped the scheme and returned all the Pokémon captured.
