Pitch-Black Pokémon
Darkrai is a Dark-type Pokémon, No. 491 in the National Pokédex, introduced in Generation 4 (Sinnoh region).
« On a moonless night, a strange incident occurred in which every one of a village's inhabitants suffered nightmares. The villagers attested that Darkrai appeared before them in these nightmares. »
Darkrai looks like a black shadow, an hourglass wrapped in a torn cloak. A white plume covers one teal eye, a red spiky growth rings its neck, and long black tatters hang from its shoulders.
It lives on Newmoon Island and is active only on the new moon or on moonless nights. It puts people to sleep to protect its territory, and only Cresselia can cure those it has touched.
In The Rise of Darkrai, it speaks by telepathy, turns into a shadow, and holds back Dialga and Palkia until Ash and Dawn place the Oración disk.
Hironobu Yoshida designed it as a personification of nightmares, akin to night hags and to the new moon opposite Cresselia's crescent. The name may come from dark and Japanese kurai, both meaning dark.
