Dusk

Dusk is the most common of Nobodies, and therefore the second weakest (next to Creeper). Dusks can be thrown off guard with a Reversal reaction command. Dusks are usually teamed up with a Creeper or some other sort of Nobody. They are first seen in Twilight Town.

Anatomy
Dusks are apparently very Heartless-like in anatomy. However, they are almost completely covered by a white latex-like suit that unzips at the mouth. What lies beneath the suit remains a mystery, however a mouth similar to that of several Heartless can be seen beneath the zipper. They are sinuous and flexible, able to bend over backwards and do flips in midair.

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.

Trivia

 * Dusks apparently have a European dialect; their only spoken phrase is, "We have come for you, my liege."
 * Apparently, Dusks do acknowledge the higher ranked Nobodies (such as Roxas, to whom the above phrase is said to) as their masters.
 * Dusks are roughly the nobody equivelent of a Neoshadow
