Dusk

The Dusk is a low-ranking Nobody that is found in Kingdom Hearts II and Kingdom Hearts 358/2 Days. They are one of the only types of Nobody known to be able to speak, and are used by Organization XIII for simple recon and courier operations. Other Nobodies can even be transformed into Dusks as an extreme form of punishment.

Kingdom Hearts II
''It is difficult to read this creature's next move, so catch it off guard with a Reversal to stop its actions. A series of attacks and Reversals can also look cool in battle!''

''Note: It lets its guard down when its attack is parried. This is also true for all Nobodies.''

Kingdom Hearts 358/2 Days
These lesser Nobodies handle simple combat, recon and courier operations. Though lacking in strength, they have a robust repertoire of close-range tactics, including spinning charge and arm thrust attacks.

Strategy
Dusks are fairly weak and require little strategy, but can be a bit troublesome in large groups at the beginning of the game, especially when paired with the Creeper Nobody. The Reversal reaction command can help as it stuns the Dusk and any surrounding Dusks and Creepers. However, although this strategy works well playing as Roxas (because of the shorter combos), when at high levels you can eliminate them with one combo. Reversal can also be used to avoid other Nobodies as they normally appear with others. Also fire magic and thunder magic can help greatly when Sora in case they surround you.

Dusks can also be battled in Kingdom Hearts 358/2 Days in several missions, all of them located in The World That Never Was.

Trivia

 * Dusks are the first type of Heartless or Nobody to be specifically mentioned outside of Jiminy's Journal; in this case, they are named by Yen Sid.
 * A glitch in the North American Kingdom Hearts II causes a Dusk to randomly pop out of one summoned by Axel while it is being fought.
