Hyperspace Fury inflicts damage, then lowers the user's Defense stat by one stage. It bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly.
It will also hit the target even if it is protected by Protect, Detect, Spiky Shield, King's Shield, Mat Block, or Baneful Bunker, and lifts the effects of those moves for the remainder of the turn; if it hits a target that is protected by Mat Block, it removes Mat Block from the target's side of the field. It also removes the effects of Quick Guard, Wide Guard, and Crafty Shield from the target's side of the field. It hits through a substitute.
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.
Other effects
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Pokémon Omega Ruby and Alpha Sapphire to Pokémon X and Y, and if a Pokémon in Pokémon Bank knows the move, it cannot be withdrawn in Pokémon X and Y. In order to be transferred to Pokémon X and Y, the Pokémon must forget Hyperspace Fury.
Using its many arms, the user unleashes a barrage of attacks that ignore the effects of moves like Protect and Detect. This attack lowers the user's Defense.
Using its many arms, the user unleashes a barrage of attacks that ignore the effects of moves like Protect and Detect. But the user's Defense stat falls.
When Hoopa is Hoopa Unbound, the move replaces Hyperspace Hole. Unlike in the core series games, using the move does not lower the user's Defense stat.
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.*
In the anime
Forming the rings
Hoopa Unbound appears through the rings
The rings seen from above
Launching the attack
The user uses a series of ring portals and launches a barrage of attacks at the opponent.
Hoopa Unbound forms six of its rings around the opponent. It then repeatedly strikes the opponent with its six fists through the rings, while watching the opponent through one of them.
