Samurott is a quadrupedal, blue Pokémon resemblant of an otter and a pinniped. It has two pairs of pointed teeth, one in the upper jaw and one in the lower. Long, white whiskers extend from its snout and head, and it has a red nose and eyes. On the back of its head is a large, rounded beige helmet-like shell with spikes and a spear-like, pointed protrusion in the front. A dull bluish-gray seashell-like carapace covers its underbelly, and its limbs are covered with beige, sectioned bracer-like coverings, that appear to be made of seashells. The forelimbs' bracers contain swords called seamitars. The lower two segments of these bracers are the scabbards for the two swords, and the upper segment and spike make up the seamitar and its handle. Samurott possess three black digits on each limb, and a fin-like, splayed tail with the innermost section being beige. This tail resembles a war fan.
When in battle, Samurott can stand on its hind legs and use one of its blades as a sword to fight. In the time it takes a foe to blink, it can draw and sheathe the seamitars attached to its front legs; one swing can fell an opponent. It can silence foes with a glare or a howl.
Hisuian Samurott is a rare form of Samurott born from the influences of the Hisui region. The shell on its head has two additional spikes on its sides, and it has a wavy protrusion at the front. Its whiskers are also wavy, with the bottom part being much longer than Unovan Samurott's whiskers. The shells covering its head and legs have sharper edges and are black with red accents, as do its seamitars, which have a wavy blade. There is one less layer of shell covering its hind legs compared to Unovan Samurott. The innermost section of its tail is longer and colored black, while its claws are red.
Hisuian Samurott is said to have a cold and hard-hearted nature, and is deft with its shell blades. Unlike its Unovan counterpart, which prefers fighting fair, Hisuian Samurott will do anything to win a battle, and prefers to use tricks such as surprise attacks and cheap shots. It remains still and silent until it sees an opponent. Then in the blink of an eye, Hisuian Samurott quickly draws out its two seamitars before instantly thrusting at its enemies. The attacks Hisuian Samurott unleashes are comparable to the ceaseless crashes of waves, and can confuse and overwhelm opponents. The wounds inflicted by Hisuian Samurott are said to take many years to fully recover from.
Both Cheren and Arata have Samurott, with the latter obtaining it as an Oshawott.
Pocket Monsters BW: Meetings with the Legends
Touya has a Samurott, which evolved from his Dewott.
Cedric Juniper has a Samurott that first appeared in At Liberty on Liberty Garden. It is used in the final battle with N, along with Black's Emboar and White's Serperior. It was formally an Oshawott intended to hand to starting trainers, until N came to attempt to liberate the starter Pokémon. The Oshawott remained, while the Tepig fled and N made off with the Snivy (the same Snivy who eventually joined White).
Samurott and its pre-evolutions are the only pre-Generation VIII Pokémon in Legends: Arceus to have not been available in previous Generation VIII games.
Compared to its pre-evolved forms, Samurott seems to be based more on the North American river otter than the sea otter. Samurott's design is also heavily based on a sea lion and an armored samurai. While it was decided that Oshawott would be based on an otter, the designers had issues in creating a fully evolved form which was more interesting than just a bigger otter standing on two legs. At that point Yusuke Ohmura went to see real-life otters at an exhibit, but his attention was rather caught by the strength displayed by some sea lions at a nearby sea lion show, and thus decided to incorporate the body shape of the latter animal into the design. Furthermore, to represent the variety in the human population of Unova, it was decided that the evolutionary families of the starter Pokémon would be based on the West, China and Japan. In the case of the Oshawott family, it had to represent Japan, and thus was based on Japanese samurai. Samurott's inspiration might also come from the lifespan of a samurai, from a child (Oshawott) to a military commander (Samurott).
Samurott's tail may be based on a Japanese war fan. The "helmet" over its head appears to be based on the rare-spined murex shell. The markings on its chest make it reminiscent of a giant otter. Its ability to withdraw, attack with, and return its blade may be a reference to iaido, a Japanese martial art that uses similar swordplay in combat. Its whiskers bear a great deal of similarity to the facial hair found in some menpō, a type of facial armor employed by samurai.
Hisuian Samurott may be based on the extinct Japanese otter and the sea otter. Its anthropomorphic aspect may come from a rōnin, which is a samurai without a lord or master to serve. The kanji 浪 from 浪人 (rōnin) literally means wave, which might have been the inspiration for the wave-like designs all over Hisuian Samurott's body. Being a rōnin was regarded as dishonorable in traditional samurai culture, and many of them end up becoming mercenaries, which may explain Hisuian Samurott's Dark type. The seamitars it keeps on its arms resemble flame-bladed swords, also known as wave-bladed swords, such as the flamberge or kris.
Samurott may be a combination of samurai and otter.
Daikenki may be a combination of 大 dai (great), 剣 ken (sword), 鬼 ki (demon), and 剣鬼 kenki (devilish swordsman).
