Hoopa
Hoopa is a mischievous Pokémon that can create a dimensional portal called the Prison Bottle. When Hoopa uses its signature move, Hyperspace Fury, it opens a large portal that sucks in everything in its path. Hoopa can also use the Prison Bottle to summon its Confined form, which is much larger and more powerful than its Unbound form.
Hoopa is said to have been created by the legendary Pokémon Arceus. Arceus gave Hoopa the Prison Bottle as a way to control its power. However, Hoopa eventually lost control of the Prison Bottle and began to use it for its own selfish desires.
Hoopa was eventually sealed away by the legendary Pokémon Dialga and Palkia. However, it was later freed by Ash and his friends. Hoopa then helped Ash and his friends to stop a group of villains who were trying to use the Prison Bottle for their own evil purposes.
Hoopa is a powerful and mischievous Pokémon, but it is also a kind and compassionate Pokémon. Hoopa is always willing to help those in need, and it is always looking for new ways to have fun.
