Late last year, hackers discovered 3 Pokemon hidden inside the code of Pokemon X and Y. These Pokemon were named Diancie, Volcanion, and Hoopa. Although they look awesome, GameFreak sadly didn't include any of them in the game at the time, leaving fans who had heard about them to just look at screenshots of the bizarre Pokemon.
Despite claims that the pokemon were fake, details about Diancie were revealed, including the fact that it had an entire movie dedicated to it, and thanks to events in stores such as Gamestop, trainers can finally see the Pokemon for themselves in their own games. That isn't all, Volcanions Pokedex entry and moves list were revealed, although there is still no sign of the Pokemon in game. However the mystery of Hoopa has only grown since the release of Omega Ruby and Alpha Sapphire.
This, Is Hoopa:
Although Hoopa hasn't seen it's official release, with the help of software such as Powersave, players have managed to get the Pokemon into their game and capture it.
Hoopa is a psychic/ghost type, and has an ability called "magician".
This is not the only case of hidden Pokemon found in the code of a game, as the hacking team "Project Pokemon" found another set of sprites belonging to the hidden Pokemon within the demo of Omega Ruby and Alpha Sapphire.
Not only was this sprite hidden within the game, players who saw this also noticed that the sprite looks very similar to Hoopa, but more threatening. At the time, players assumed that this was the mega evolution of Hoopa, and that the Pokemon would be added later during an event of some kind. Now, we know that the sprite is actually an alternate form that Hoopa can take. We know this because, once Alpha Sapphire and Omega Ruby were released, players who used Powersave to insert Hoopa into their games found that it triggered a strange new event inside PokeMarts.
See the video below:
The basic gist of the video is that a new PokeMart employee will appear in the corner of the building who, when spoken too, will tell you a story about how he foolishly traded Mart goods for a useless item. Once the employee finishes telling his story, he proceeds to give you the item (named "Prison Bottle"), which is apparently supposed to make Hoopa become "Unbound" for three days. And sure enough, players who used the item on Hoopa saw their prized Pokemon transform into this;
This is the alternate version of Hoopa, known as Hoopa Unbound. This is interesting for those who like to look into the lore of Pokemon and their creation, and although the Pokemon does not seen very threatening in the image above, but compared to its original form, it's a lot more menacing. The in game description of the Prison Bottle seems to back this up as it says "A bottle believed to have been used to seal away the power of a certain Pokemon long, long ago."
This begs the question, Just why would you want to seal away the power of a Pokemon? With Pokemon such as Palkia and Dialga on the loose, what could possibly be bad enough to be stripped of its power? Well, there is no official answer to that, but there are a lot of player theories. Most of which believe that it has something to do with one of Hoopa's moves called Hyperspace Fury. (See below)
Some players have likened the rings that Hoopa uses during the move to those that the player must walk through in order to find legendaries in Omega Ruby and Alpha Sapphire:
This, when added to the lore behind Hoopa, has many players convinced that your encounters with the legendaries during your adventure are the doing of Hoopa.
A brief recap: Hackers found a Pokemon in the code of X & Y that, when transferred into Omega Ruby and Alpha Sapphire, triggers an event in PokeMarts where an NPC will say the following to you if you have a Hoopa in your party:
"No way! Could that be the Mythical Pokémon Hoopa that you have there with you?" Options: Yes | No
No: "Oh, I was mistaken? Sorry about that…"
Yes: "Whoaaa! I can't believe it's true! See, I travel around the world, trying to solve its many mysteries. I've been researching supernatural events that have occurred over the last 100 years. One thing I've found is that the Mythical Pokémon Hoopa is connected to many of these strange events! I've also managed to come across some information about the mysterious power that Hoopa appears to wield. So, without further ado, I'd like to share my findings with you! After all, you're actually traveling with Hoopa–the very subject of my research!" Options: Its mysterious rings | The secret of its lair | Its deeds and exploits | Nothing
Its mysterious rings: "It's said that Hoopa can use the power of the three rings it adorns itself with to move objects about as it pleases… That's not all! I've also heard that when Hoopa unleashes its full power, the size of the rings can grow up to multiple miles in length! With such massive rings, apparently it can transport even entire islands!"
The secret of its lair: "It's said that Hoopa's lair is overflowing with the objects and treasures it nabbed over the years, claiming them for its own. Rumor has it that there are mountains of gold and silver treasures that it took from ancient kings and wealthy land barons. I hear that Hoopa's lair is in an oasis in the desert, but no one's been able to find the place!"
Its deeds and exploits: "There's a tale about an organization that tried to manipulate Hoopa's power for their own benefit. After a while, certain objects that belonged to the organization mysteriously began to disappear. Everything from weapons and vehicles to money… It all began to vanish one by one. The organization got scared and decided to hole up inside of their headquarters. Once they did, things stopped disappearing! Just like that! Relieved that it was finally over, the organization finally decided to step outside. It was then that they discovered their headquarters had been transported wholesale to somewhere in the middle of a desert! Terrified of what they had unleashed, the organization promptly disbanded."
"Whether Hoopa becomes a trustworthy partner or ends up bringing about great misfortune depends entirely on the Trainer. I hope you don't forget that. I think Hoopa'll turn out right as rain with you at its side, though! You look like a Trainer who knows how to take care of his Pokémon and treat 'em right. Well, I hope you end up having lots of fine adventures with Hoopa! Have fun!"
Based on this dialogue, my theory is:
"Hoopa is a legendary Pokemon that can transport things using its three rings. This makes sense within Alpha Sapphire and Omega Ruby as legendary Pokemon are usually found on strange, remote islands, meaning that you would have to travel through a hoop to get to them. Another thing that makes this theory more likely is that each day, 3 of these locations appear on your map. 3 locations, 3 rings. Also, the fact that the game includes legendaries from different games makes it likely that there could be another legendary causing these rings to appear, that legendary being Hoopa."
As stated earlier, that's just a theory. And until GameFreak release the Pokemon officially, that is likely to be all that we will have. Stay tuned for more news on this mysterious Pokemon.
