Hoopa is a Mythical Pokémon first discovered in the Kalos region. Hoopa has two Formes: Confined Form and Unbound Form. It is said to be able to use its gold rings to warp space in order to take things it likes and carry them away into alternate dimensions. Using an item known as a Prison Bottle, Hoopa Confined can transform into Hoopa Unbound and remain so for three days, after which it transforms back to Hoopa Confined. It will also transform back if deposited in the PC.
