Dusk

The Dusk is a low-ranking Nobody that is found in Kingdom Hearts II and Kingdom Hearts 358/2 Days. Dusks are the most common Nobodies. They are the only types of low Nobody known to be able to speak, and are used by Organization XIII for simple recon and courier operations. It is possible for other higher-ranking Nobodies to 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, which pulses weakly with light. Its feet and hands are pointed and lack digits, and its 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 beings of neither Light nor Darkness, but are closer to the Darkness.

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 ease. 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 playing as 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.

Kingdom Hearts 358/2 Days manga
Dusks appear to be very mischievous, drawing on Roxas's face with markers during his early days in Organization XIII, and when he fell into a coma, making him look like on Day 29, and making him look like Xigbar on Day 30. Afterwards, Xion would clean his face daily, but this only prompted them to draw in permanent marker. They also seem to perform servitude roles for the other members of the Organization, such as giving Xaldin a shave.

Trivia

 * Dusks are the first common enemy to be specifically mentioned outside of Jiminy's Journal; in this case, they are referred to as such by Axel and 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.
