Scatterdust Pokémon
Scatterbug is a Bug-type Pokémon, No. 664 in the National Pokédex, introduced in Generation 6 (Kalos region).
« The powder that covers its body regulates its temperature, so it can live in any region or climate. »
A black larva with a large head split from forehead to mouth, beige eyes with square pupils, and one pointed tooth. Three white hairs, a white ruff, and a beige spot mark the rear.
It turns plant poison into black powder. On contact, the powder paralyzes, discourages bird Pokémon, and regulates its temperature for any climate. It evolves into Spewpa, then Vivillon.
Ash and his friends rescue one from Dolan and his Diggersby; it evolves into Spewpa. Goh catches one in Shalour City, and it later returns.
Scatterbug is based on a caterpillar, like carpet-moth or silk-moth larvae. Its name may combine scatter and bug, and possibly litterbug.
