Samurott is a quadrupedal pokemon, which is different to its previous evolutions which were bipedal. It has a pointed nose, with large pale-blue moustache/goatee-like growths protruding from it, which it has developed from Dewott's whiskers and Oshawott's dimples. On the back of its head, Samurott has a large yellow conch shell with a very long horn with two spikes on it. It has a long dark-blue body with a light blue-gray belly and four legs with yellow armor-like shells divided into threes on them, those on it's front legs are in fact where its swords, known as Seamitars are stored. Its tail resembles that of a fish and is heart-like shaped with a small shell in the middle that makes it look like a deformed oval. It eyes have reverted back to how they were with Oshawott's as they are now white with colored pupils as opposed to Dewott's eyes, which were black with white pupils.
It is able to silence its opponents by glaring at them. It can also terrify opponents by howling, which can be heard from miles away. Unlike Oshawott and Dewott, Samurott can walk on all fours or presumably two as the shells on its forelegs are sheathed for two large swords. Samurott's shell arrangements are somewhat based on samurai armour, hence its name.
Samurott evolved from Dewott starting from level 36. Samurott is the final form of the starter Pokémon Oshawott.
