Dark Void puts the target(s) to sleep. It can only be used by Darkrai.

It targets all adjacent opponents i.e. the opposing Pokémon in a single battle, both opponents in a double battle, three opponents if in the center of a triple battle, or two opponents if situated at the side in a triple battle. Each target is counted as a separate attack so it may succeed for all, any or none of the targets.

Sleeping Pokémon cannot move (with some exceptions such as Snore). Sleep lasts for 1-3 turns.

Pokémon with the abilities Insomnia or Vital Spirit, or those behind a Substitute cannot be put to sleep.

When a Pokémon is holding Darkinium Z and uses its Z-Power, Dark Void turns into Z-Dark Void and eliminates any stat drops applied to the user, in addition to its usual effect as above.
