Samurai

The Samurai is a high-ranking Nobody controlled by Roxas that is found in Kingdom Hearts II and Kingdom Hearts 358/2 Days.

Kingdom Hearts II
When Sora arrives at Memory's Skyscraper, a pair of Samurai Nobodies block Donald and Goofy while others surround Sora and transport him to the Station of Serenity, where Roxas attacks him.

Design
A Samurai has a distinctive cylindrical head that is a darker shade of grey than the most of the rest of its body. This head bears six diagonal slits on the front, three on each side. The majority of its body appears to be covered in a grey jumpsuit with bell sleeves and a lighter grey seam going down the front. Each sleeve has the Nobody emblem printed on them, and only the Samurai's black hands are visible. The black, featureless, pointed feet of the creature sprouts out from each of the legs of the jumpsuit.

There is also a dark grey belt-like pattern that wraps around its waist, though it does not seem to have a purpose. The (also grey) swords used by the Samurai usually just float very close to it, either crossing behind its back or resting at either of its hips. The shape of certain parts of a Samurai's body, particularly its legs, have a vague resemblance to the design of the Nobody symbol, and it can, like all lesser Nobodies, contort itself in normally impossible ways.

The name "Samurai" is a reference to the Final Fantasy job class of the same name.

Strategy
Samurai Nobodies do not attack very spontaneously. Rather, these Nobodies will remain calm and poised for a long while before sending a flurry of blade swipes at Sora. Moving slowly, but gracefully, Samurais wait for Sora's attack before attacking themselves. Their Reaction Command, Duel Stance, results in a classic stand-off between Sora and the Nobody. The command list then goes blank. Once the command The End appears, the command must be selected before the Samurai makes its move. If not, the Samurai will strike first and deal a fair amount of damage. If succesful, Sora will slice through the Samurai and defeat them with one single slice. If there are other Nobodies or Heartless in close proximity to Sora's Reaction Command strike, they will also be affected by the attack. In Kingdom Hearts II Final Mix, the battle against Roxas features a very similar reaction command to his Samurai's "Duel Stance". In 358/2 days, these nobodies are the most powerful variety you will encounter, they deal high levels of damage, and since you lack the Duel Stance command, they will be far harder to take down than in other games. However, if they are blocked when attacking with both swords, they will get staggered. The Samurais also have a low defense but a high attack.
