This is Hoopa. A pokemon that has an extraordinary power. Hoopa can summon any pokemon or even humans at any time he wants. He can do that with his golden rings/hoops that he carries around everyday.

One day, he got mischievious and summonded Dialga and Palkia! They got into a BIG fight, and nearly wrecked the whole place when a brave trainer stopped the whole thing just in time.

But then there was anther time when Hoopa summoned Groudon and Kyogre, another two legendary beasts. And like the two last legendaries, they got into a HUGE fight and nearly destroyed earth again! But good thing that the trainer showed up again and stopped the whole madness.

Hoopa continues to summon more and more legendaries but then each time he always mess up and end up destroying everything! Mew and Mewtwo fought...

And the three legendary birds too...

Even Zekrom and Reshiram...

And not to even mention Cresselia and Darkrai...

Every legendary and mythical pokemon was out of control because of Hoopa!

Hoopa was very sad. "I just wanted to have some fun but I didn't want to ruin anything!" Hoopa said. "Now everyone is going to hate me!" He thought. And he lay there, feeling sad.

But then a little green curious pokemon appeared! It was Celebi! "Whats the matter Hoopa? You look sad." She said.

"Whats the matter with you?"

Hoopa told her the whole story...about the legendary pokemon...and the trouble that he caused...

And I...just don't want to be myself anymore...

"Then you should use your gifted powers on stuff that helps people, instead of causing mischief for everyone." Celebi said. "Use your powers wisely and be yourself at the same time! It's possible!"

"You really think so???" Hoopa asked. "Yes! In fact, I think your power of spawning anything is awesome and cool!" The little green pokemon replied. "Wow! Thank you!" Hoopa said. Feeling way more confident.

"I am going to help people right now! Wanna come along?"
