Bramblin is a Pokémon that resembles a tumbleweed. It has small, rhombic, black, leaf-like eyes with thin red pupils that float inside its body, which itself comprises brownish yellow, jagged, thorny plant stalks that point up and curl slightly inward to form a spherical shape. The eyes don't blink and instead flip and rotate to express Bramblin's emotions. The stalks are held together by what appears to be the remnants of roots on the underside of its body.
Bramblin are created when wandering souls unable to move on get tangled and fused to dried grass. Bramblin's main form of locomotion is the wind, which blows it uncontrollably to destinations unknown. Bramblin despises getting wet. It makes its habitat in dry, rocky regions such as deserts.
Bramblin and its evolution, Brambleghast, are the only known Pokémon that can have Wind Rider as an Ability.
Bramblin appears to be based on tumbleweeds — certain types of plants which, when mature, have most of their cells dry out and die so that the wind can pick them up and allow them to disperse their seeds, hence Bramblin's Ghost type and Ability. Bramblin's secondary Ghost type may also be derived from the association of tumbleweeds with ghost towns and empty deserts.
Bramblin's cry is reminiscent of the whistling sound at the beginning of the theme from The Good, the Bad and the Ugly, perhaps alluding to the tumbleweed being a common sight in spaghetti Western movie scenes. Bramblin not knowing where it is going may reference the drifter character archetype that is a staple of the Western genre.
Bramblin may be a combination of bramble and rambling, goblin, or gremlin.
Anokusa may be derived from the phrase あの草 ano kusa (that grass).
