Hyperspace Fury can only be successfully used by Hoopa as Hoopa Unbound (or a Pokémon that has transformed into Hoopa Unbound). If this move is used by any other Pokémon (including via Assist or Sleep Talk), the move will fail, even during Pokémon Contests. If using the move as a Pokémon other than Hoopa, the battle text "But <Pokémon> can't use the move!" will be displayed; if used by HoopaConfined, the battle text "But Hoopa can't use it the way it is now!" will be displayed.
Hyperspace Fury does not exist in the game data of Pokémon X and Y. As a result, a Pokémon knowing Hyperspace Fury cannot be traded from Pokémon Omega Ruby and Alpha Sapphire to Pokémon X and Y, and if a Pokémon in Pokémon Bank knows the move, it cannot be withdrawn in Pokémon X and Y. In order to be transferred to Pokémon X and Y, the Pokémon must forget Hyperspace Fury.
It breaches an enemy's Protect, Detect, etc., and it hits without fail.* It breaks through the enemy's Protect, Wide Guard, Quick Guard, Mat Block, King's Shield, or Spiky Shield to damage the enemy. It never misses.*
