"There are many Pokémon in this world, Leon. So many different Pokémon inhabit this world, so much that some Pokémon only live in certain places, on certain regions. Scientists around the world are still discovering Pokémon. Many remain a mystery to us today, such as legendary Pokémon."
"Legendary Pokémon? What are those?"
"Legendary Pokémon are very rare. Legendary Pokémon are Pokémon that, in a sense, have achieved a certain level of god-like power, so much that some are seen as ancient deities, such as Dialga and Palkia."
"Dialga... and Palkia?"
"Yes. The legendary Pokémon Dialga and Palkia are two mythical Pokémon that are seen in the Sinnoh region, a faraway land thousands of miles away from Johto. Dialga and Palkia are known for being the creators of time and space. People in the Sinnoh region seem to know much about these two Pokémon. They've had stories about these two Pokémon since ancient times, which leads to another mystery about these legends. It seems that legendary Pokémon also possess imortality. One such Pokémon that is known for its immortal lifestyle is Arceus. Arceus has appeard in the first records of history, maybe even before those times. It is said that Arceus was born before the universe was created, and shaped and created this world. We don't have official evidence to prove these myths to be true, but there is definitely something mythical about the Alpha Pokémon."
"But wait, if legendary Pokémon have so much power, then why don't they rule the world, or something like that?"
"We don't know. Some Pokémon have caused mischief and disaster, such as Groudon, Kyogre, Giratina, Darkrai, Tornadus, and Thunderus, but there have always been people or Pokémon that stop them. It is unknown why Pokémon like Rayquaza, Cresselia, and Landorus take it upon themselves to stop other Pokémon's wrath, but it seems as though these Pokémon serve as the counterparts of the Pokémon they stop, always keeping them in check, making sure they don't harm anyone."
"So when legendary Pokémon like Rayquaza or Landorus stop other Pokémon, they have to fight them?"
"Oh yes. These battles are astonishing. Take the trio of Tornadus, Thunderus, and Landorus, for example. Tornadus and Thunderus fly all over the Unova region, causing massive damage and multiple catastrophes, but soon after, Landorus will chase the other two, and stop their wrath. Those Pokémon fight with such power, it's absolutely terrifying, but Landorus always beats the other two. It seems that Landorus protects people and Pokémon from Tornadus and Thunderus, even if it means Landorus has to fight extremely brutal fights. The same goes for Groudon, Kyogre, and Rayquaza. Groudon and Kyogre will wage wars against each other, trying to expand land and sea to defeat the other, but Rayquaza will appear and end their wars, all the time. Some of these Pokémon are so powerful, it takes two legendary Pokémon to stop one, like with Dialga, Palkia, and Giratina. Giratina will roam a place known as the Distortion World, looking for a place to escape. When it finds one and manages to flee, Dialga and Palkia will join forces and stop Giratina. This is very interesting, seeing as how Dialga and Palkia are enemies."
"Wow... That's incredible."
"It is! Some scientists study the reasons why these Pokémon do or act the way they do. They haven't found that answer yet, but they did seem to notice something."
"Like what?"
"Well, with all these disputes between legendary Pokémon, with all these epic battles, these Pokémon seem to have left an... impact."
"An impact?"
"Yes... Allow me to explain. Every time these Pokémon battle, they leave tiny, tiny bits of a strange energy. These tiny bits eventually pile up, and combine to form a stronger energy. Take, for example, Pokémon like Dialga, Palkia, and Giratina. We already know that these Pokémon are capable of traveling throughout time and space. With such incredible abilities, what do you think happens when these powers clash? The answer is simple: Something new is formed. Some kind of... new energy forms throughout time, space, and distortion, so much that the three combined cannot contain it. So, one might ask, where does this energy go? That part is unclear to us, but we do know that it flows and travels to unknown places. Areas far, far away from this world, from this universe. That energy travels to other places that also resonate this type of energy, though we don't know how the energy on the other side forms. We're not sure what to make of this energy, as we don't even know what it is, but we plan to soon study this new energy, to see if we can control it."
"...What?"
"Uh... I suppose I let my mouth run off a bit. In short, when these Pokémon fight, they create new energy that travels to unknown places."
"...Oh."
"Well. Now that we have the explanation of Pokémon done, albeit longer than any other I've ever given, it's time for you to get your very own. Go on, Leon, choose one." Professor Elm gestured toward a large capsule.
Leon walked up to the large capsule, with three Pokéballs on display. "Wow..." Leon stared at the red-white capsules.
"What'll it be?" Professor Elm rotated the Pokéballs' display case. He turned on a monitor, revealing a sleeping Pokémon. "Do you want Chikorita, the Leaf Pokémon..." Elm rotated the display case. The monitor blinked, showing another sleeping Pokémon. "Cyndaquil, the Fire Mouse Pokémon..." Elm rotated the case one last time. Once again, the monitor blinked, revealing another sleeping Pokémon. "Or Totodile, the Big Jaw Pokémon?" Professor Elm looked back at Leon, with a small smile. His hand gestured towards the case. Leon looked at Elm.
Leon stared back at the Pokéballs. "Hmm... I think I'll have..."
