Samurott has a pointed nose, with large mustache/goatee-like growths protruding from it, which it received from Dewott's whiskers and Oshawott's dimples. On the back of its head, Samurott has a large 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 shells divided into threes on them. Its tail makes a heart-looking shape with a chunk of its shell in the middle that makes it look like a deformed oval.
It is able to silence its opponents by glaring at them. It can also terrify opponents by howling, which can be heard for miles. Unlike Oshawott and Dewott, Samurott can walk on all fours or presumably two as the shells on its forelegs are sheathes for two large swords. Samurott's shell arrangements are somewhat based on samurai armor.
Samurott evolved from Dewott starting from level 36. Samurott is the final form of the starter Pokémon Oshawott.
