The Pokemon Company has officially unveiled Hoopa Unbound, this will be a new form of the legendary Pokemon Hoopa.

Here is what we know about the Pokemon:

Hoopa Unbound is the new and truest form of Hoopa, which until now has had its power sealed away. The rings Hoopa Unbound carries have the power to bend dimensions and are said to allow it to seize anything in the world. After its transformation, Hoopa Unbound is far larger than it was in its previous form, with six huge arms and a greater number of its signature dimension-bending rings.

We also know that Hoopa Unbound has the following stats:

Category: Djinn Pokémon
Type: Psychic/Dark
Height: 21’04” [6.5 m]
Weight: 1,080.3 lbs. [490.0 kg]
Ability: Magician

Hoopa, is the 720th Pokemon in the pokedex, however similar to Pokemon of the past it is impossible to get the Pokemon by general means in Omega Ruby and Alpha Sapphire. However I would imagine we will get the Pokemon Hoopa by some kind of event, the details of which should be shared in the near future.
