When I first went to the Nameless Cavern, a place that requires Soaring to go, I caught an Azelf. I noticed that Azelf came out of a portal right before the battle started. The portal had a golden rim and a dark opening inside. I know that Azelf is supposed to live in a lake, but it shouldn't be inside a cave with barely any water. Then, I found Tornadus come out of a portal as well. I got shocked, because Tornadus belongs in the Unova region. Then, Virizion came out of a portal. As I found more legendaries, more portals appeared. With my knowledge of Hoopa, I know that Hoopa can transport things big as an island to a different place using its rings. Then I found out that Hoopa Unbound's hole in its chest looks exactly like the portals you have to touch in order to fight a legendary. Is Hoopa Unbound responsible for transporting the various legendaries from their original habitats to the Hoenn region?
