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.
