Dewott is an otter-like Pokémon that is light blue with a navy blue "apron" around its thighs that carries two scalchops. It has four white whiskers and a platypus-like tail and small black ears. It also bears a similarity to Marshtomp in regards to color, whiskers, and the scalchops on its legs.
Dewotts live in the water and can only be found in the Unova region.
In the anime
A Dewott was seen in episode 4 of Pokémon Best Wishes when it was battling another trainer's Servine and won, despite Servine having a Type Advantage. It then battled Ash's Pikachu, but the battle was interrupted.
Cilan's rival ,Burgundy, owns a Dewott, as seen in Episode 19. However, it lost to Cilan's Dwebble in battle.
Dewott was first seen on a Beta artwork of the Pocket Monsters Best Wishes anime series along with Servine, Woobat, and Axew. On September 1, 2010, an image containing all of the evolutions of the starter Pokémon was shown on a Japanese forum. It was officially revealed on the October issue of Coro Coro on September 11, 2010.
Dewott's name comes from "dew" and "otter." It is also possible that its name is a pun on the British idiom "Do what?" to express confusion.
The tuft of fur on Dewott's head may become the shell atop Samurott's head when it evolves.
Dewott's Japanese name, Futachimaru, could possibly originate from "fu" as in Kung Fu (since it carries the design of a Kung Fu warrior with a shield around its waist and tuft of fur atop its head), chi from chibi (since that's a Japanese style of drawing and Dewott's eyes resemble chibi style) and "maru" to have its name similar to Mijumaru, or Oshawott, its pre-evolution. It's also possible that it comes from Futachi, "two" in Japanese, and "maru", just to match Mijumaru .
