The Pokémon series is often praised for its lighthearted tone. This playfulness has drawn both players, old and new, into the series for over two decades. Undoubtedly, the inherent "happynature that goes along with Pokémon has given it the positive image it has today.

However, sometimes mysterious occurrences take place in Pokémon's otherwise strange world. Throughout each region, there are tall tales and legends abound, ranging from theories about particular creatures to falsified identities of important characters. Here are 3 of the most compelling mysteries in the Pokémon franchise.

Giratina Is The Pokémon Of Gravity, Not Antimatter

In the Sinnoh games, Dialga is supposed to represent timePalkia is supposed to represent spaceand Giratina is supposed to represent antimatterHowever, one theory suggests that Giratina's abilities, origin form and distortion world all have more correlations to gravity rather than antimatter. There is a shocking amount of evidence to support this theory, as well. In Einstein's old relativity theory, he states that gravity is a distortion of time and space. Given that both Dialga and Palkia represent two sides of that coin, it makes sense that Giratina, a creature that can be found in a location called the distortion world, represents the physical embodiment of distortion itself.

On top of this, in Pokémon Platinum, the distortion world itself constantly shifts its center of gravity as the player traverses through it. This makes sense given that Giratina, the possible embodiment of gravity, lives in a place that distorts this very concept. It is also established in the Sinnoh myths that Dialga, Palkia and Giratina were all created by Arceus at the same time. Once again, the correlation between gravity, time and space justifies this. Overall, the theory fits very well logically and considering Sinnoh's mythology.

Is N A Zoroark In Disguise?

ZOROARK - MASTER OF ILLUSIONS

This theory sounds silly on paper. However, there is an alarming amount of evidence that suggests N from Pokémon Black and White is the illusionary creature, Zoroark. A small piece of evidence is a vague physical likeness. Many have noted N and Zoroark have long hair; however, this is mostly where physical similarities end. The validity of this theory is more so confirmed through the story of Black and White, as well as the strange occurrences that surround N.

Of course, N's goal within itself is one that would benefit Pokémon as he wishes to liberate the creatures and separate them from their trainers. N also has a Zoroark in his party. The real selling point of this theory comes into play when inspecting N's behavior and past. In one instance, the player is made to interact with a Zoroark before it quickly runs away. Upon following the Zoroark, the player is greeted by N and the Pokémon is nowhere to be found. There is also a flashback in the game that is triggered by interacting with a Zoroark. However, instead of the scene being through the Pokémon's point of view, it is through N's. While none of these details confirm that N is a creature in disguise, they do introduce it as a genuine possibility.

Who Were The Legendary Beasts?

The legendary beasts of the Johto are perhaps the most well regarded legendary trio and for a good reason. All three have beautiful and recognizable designs that reflect their typing and personalities quite clearly. On top of this, they have an intriguing origin story that is steeped deep within Johto's mythos. The story of how the three beasts came to be started when three Pokémon, a fire type, a water type and an electric type, lived in the tower. However, a bolt of lightning struck, setting the tower on fire. The creatures within the tower died until Ho-Oh granted them a rebirth. This rebirth turned the three creatures into the legendary trio Entei, Suicune and Raikou.

Many fans have speculated as to precisely what Pokémon the beasts were before their rebirth. A very plausible theory suggests they were Vaporeon, Jolteon and Flareon before their legendary status. Stat wise, the legendary beasts are quite similar to the Eevee evolutions. Also, the beast's hidden abilities are the same as the evolution's regular abilities. Although this case hasn't been confirmed or denied yet, there is enough evidence to at least suspect the beasts may have been part of the Eevee family before their rebirth.
