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.

Design
A Dusk has a thin, sinuous body that is capable of dumbfounding feats of flexibility. It has a large, cylindrical head with a flat top that is emblazoned with the Nobody symbol. Its body seems to be covered in a light grey jumpsuit, and its "mouth" is actually a zipper that undoes itself to reveal its actual, grey, sharp-toothed mouth underneath. It appears to be fairly muscular, though its arms and legs are very thin. The sides of its body are lined by a black line. Its feet and hands are pointed and lack digits, and is hands each sport two black bands around them.

The Dusk's name refers to the period of time when the sun begins to set and twilight begins to set in. This emphasizes how Nobodies are neither beings of Light, nor Dark, but are closer to the Darkness.

Their Pureblood Heartless counterpart is a neoshadow.

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 common enemy 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.
 * In the Kingdom Hearts 358/2 Days manga, they appear to be very mischievous, drawing on Roxas' face with markers during his early days in Organization XIII, and when he fell into a coma (even one time making him look like Xigbar). Afterwards, Xion would clean his face daily. This only prompted them to draw in permanent marker.
