Xerneas and Yveltal on the cover of the Pokémon X & Pokémon Y: Super Music Collection, by Yusuke Ohmura

Aura trio (Japanese: カロス神話(しんわ) Kalos myths) is a fan term for a group of Legendary Pokémon consisting of Xerneas, Yveltal, and Zygarde. Xerneas and Yveltal, often described as a pair, are known to reside only within the Kalos region, while Zygarde's Cores and Cells are scattered across the world, notably in Kalos and Alola.

Xerneas and Yveltal are the game mascots of Pokémon X and Y, respectively. While Zygarde is often decpited as the mascot for Pokémon Legends: Z-A. As a game mascot, Xerneas is depicted in its Active Mode and Zygarde in its Complete Forme.

The three species are representative of life and the ecosystem, more accurately. Xerneas spent a thousand years sleeping in the form of a tree before reviving and sharing eternal life. Yveltal absorbs the life-force of all living things and turns into a cocoon when its life comes to an end. Zygarde awakens when the natural order of the ecosytem is disrupted. Zygarde's Complete Forme is known to surpass the power of both Xerneas and Yveltal. Xerneas is categorized as the Life Pokémon and has the Ability Fairy Aura, while Yveltal, the Destruction Pokémon, has the Ability Dark Aura. Zygarde, categorized as the Order Pokémon, has the Ability Aura Break, reversing the effects of the Fairy and Dark Auras. Stylistically, they are representative of the Latin letters of X, Y, and Z.

History

Core series games

A legend says Xerneas and Yveltal are great forces, being capable of giving and stealing life energy respectively. Xerneas shares life by glowing its horns in seven colors, while Yveltal's feathers near the gray pattern on its chest glow when it is about to steal life energy. When they are at the end of their lifespan, Xerneas releases all of its life energy into all the living things in around it, while Yveltal expands its wings and steals all of the life energy of every living thing around it. Afterwards, they transform into a tree and a cocoon respectively, to sleep for 1,000 years. Zygarde Cells are always monitoring the balance between Xerneas and Yveltal, and whenever it is disrupted or destroyed, Zygarde comes to unleash its wrath. These three Pokémon, according to Professor Sycamore, are "incarnations of nature that take care of the land". Research conducted by Mable of Team Flare indicates that Xerneas and Yveltal possess mysterious abilities to manipulate and control life, which science has yet to fully understand.[1][2] In Pokémon X and Y, there are two legends involving Xerneas and Yveltal as told by a Monsieur in Anistar City depending on which version.

According to one tale in Pokémon X, Xerneas used its shining horns to brighten the Kalos region 800 years ago. During that very moment, both humans and Pokémon were filled with the energy and vitality unleashed by Xerneas. At the same moment, a vast forest was born with Xerneas at the center of it. This legend foretold that when Xerneas reaches the end of its thousand-year lifespan, Xerneas will unleash its remaining life energy and share it with any living things that are near it. A second legend suggests Xerneas appeared 3,000 years ago during a terrible war that engulfed the Kalos region and supposedly rescued every Pokémon that was wounded during the course of it, but it is unknown if this is true. After releasing its remaining energy, Xerneas transformed into a dried-up tree. It has since remained hidden deep within the forest slumbering.

According to one tale in Pokémon Y, Yveltal engulfed the Kalos region in darkness 800 years ago by spreading its ominous wings. Throughout the land, both humans and Pokémon begin to die one by one due to Yveltal's darkness. Afterward, Yveltal lets out a piercing cry before disappearing to an unknown location. The stories say that when Yveltal reaches the end of its thousand-year lifespan, it absorbs the lifeforce of all living things near it in order to transform its own energy. A second legend claimed Yveltal appeared during a terrible war that the Kalos region was in 3,000 years ago. The story claimed a Pokémon appeared during the war and drained the life force out of many living beings, killing them in the process. Some believed the Pokémon was supposedly Yveltal, but it is unknown if this is true. Apparently, when Yveltal finishes storing the life force it obtained, it will transform into a cocoon-like state. There it remains hidden deep within the mountains.

Pokémon the Series

In Pokémon the Series, a legend told in The Legend of X, Y, and Z! says that a long time ago, an oracle named Olympica, had made a prediction that the Yveltal would absorb the life form of all living things. The village's chief decided to send out a man named Jan to find and defeat Yveltal, however, the chief's daughter and Jan's lover, Aila, was deeply worried and tried to stop him, but he promised her he'd defeat the Destruction Pokémon. Suddenly however, Yveltal appears and starts fighting Jan, turning the bodies of his Talonflame and Aila into stone by using its Oblivion Wing. Afterwards, Yveltal goes into its cocoon form and falls into a slumber, sucking all the life around it, leaving the area completely devoid of life. Olympica eventually tells Jan about Yveltal's counterpart, Xerneas and instructs him to find it.

Eventually, Jan manages to find Xerneas in its tree form being used by the ruler of a small kingdom, Veofum, who angered by failing to control Xerneas's power, orders his advisor to burn the tree. Jan arrives right in time riding his Gogoat, only to be captured by Veofum's men as he pleads the ruler to put out the fire so Xerneas won't suffer. Suddenly however, many Zygarde Cells start becoming visible around them and then all combine into 50% Form Zygarde to save Xerneas and protect the ecosystem, using Land's Wrath to punish the people and destroy their kingdom, before returning to its cells form. Afterwards, Xerneas returns to its neutral form and leaves as Jan begs it to heal his homeland.

Jan returned in sadness to his homeland to protect it and moves the statue of his lover somewhere else, before encountering Xerneas there once again, that uses its power to heal the lifeless land, returning it to its original glory, but there was nothing it could do for Aila's petrified state, who'd be taken care of by Jan as years passed by. Professor Sycamore believes that both Xerneas and Yveltal are incarnations of nature that take care of the land but when the natural order is undone, Zygarde appears to balance it.

Moveset comparison

Xerneas's signature move is Geomancy, a non-damaging Fairy-type move that charges on the first turn. On the second turn, it causes Xerneas's Special Attack, Special Defense, and Speed to increase by two stages. Yveltal's signature move is Oblivion Wing, a damage-dealing Flying-type move that inflicts damage on the target and restores the user's HP by 75% of the damage dealt. Zygarde's signature moves are Land's Wrath, Thousand Arrows, and Thousand Waves, damage-dealing Ground-type moves, and Core Enforcer, a damage-dealing Dragon-type move.

Diancie and the Cocoon of Destruction

Xerneas and Yveltal both debuted Diancie and the Cocoon of Destruction as major characters. In the movie, Diancie had a responsibility as the Princess of the Diamond Domain to maintain the balance of its ecosystem by making a new Heart Diamond. However, as she lacked the power to create a stable Heart Diamond, she sought help from Xerneas, as its Fairy Aura could revitalize energy.

As Diancie's journey began, she bumped into Ash and his friends, who soon decided to accompany Diancie in her pursuit of Xerneas. As the team pursued the Legendary Pokémon, several thieves—Merilyn, Riot, Argus Steel and Millis Steel—were also in pursuit of Diancie to take advantage of her ability to create diamonds. The group were able to catch a moment with Xerneas and bathed under its Fairy Aura, as Xerneas told Diancie that Fairy Aura was not what she needed, but there was a power inside her.

The chase led to Allearth Forest and the group's activity awakened and enraged the Cocoon of Destruction, Yveltal. Yveltal went on a rampage with its Oblivion Wing, petrifying the thieves and their Pokémon. Yveltal eventually gained on the group, continually firing harmful beams that triggered extreme emotions within Diancie, enabling her to Mega Evolve. Before Ash's Pikachu was completely petrified by Yveltal, Xerneas appeared to battle it, and its mere presence was able to quell Yveltal's rage. Yveltal finally flew calmly away from the forest. Soon after, Xerneas used its Fairy Aura to revitalize the forest and revive the Pokémon and people petrified, including Pikachu. Xerneas then transformed into its dormant form to look over Allearth Forest for the next thousand years.

Pokémon the Series: XY

A Xerneas appeared as a silhouette in Foggy Pokémon Orienteering!. However, its antlers could clearly be seen.

A Zygarde Core, named Squishy, has a major role in the XY&Z arc of Pokémon the Series: XY as a target of Team Flare. It traveled with Ash and his friends in Bonnie's bag for the duration of the arc, bonding with the little girl. Meanwhile, its fellow Zygarde Core, codenamed Z2, was targeted and ultimately captured by Team Flare. At the climax of the series, both Zygarde Cores fell under Team Flare's control and caused devastation around Lumiose City. Once freed, they joined together into Zygarde Complete Forme to stop the Giant Rock. Near the end of the series, the two Zygarde Cores recruited Ash's Greninja to help clean up the aftereffects of the Giant Rock's influence on Kalos.

All three appeared in The Legend of X, Y, and Z! during a flashback.

X & Y arc

Xerneas in its Active Mode, and Yveltal debuted in An X-cuse to Come Out and Play. The two faced each other in a battle, which caused chaos and destruction in Vaniville Town. The two eventually stopped fighting and returned to their dormant tree and cocoon states, which were sought after by Team Flare to power their ultimate weapon. Later after being revived from its tree form, Xerneas took on its Neutral Mode. Afterwards, it befriended and was caught by Y and is nicknamed Xerxer. When Malva arrived and revealed that she had caught Yveltal, the two nearly clashed again before Xerosic stopped them, stating that Lysandre ordered a ceasefire as the powers of the two would cause an endless war. Xerxer agreed with this and escaped carrying Y and her friends.

Later, Xerxer was stolen and taken control of by Essentia in Anistar City, where she used it to fight against X and Y. In the middle of the fight, Zygarde appeared to stop Xerneas. When Zygarde started absorbing power from its surroundings, it let its guard down, allowing Essentia to capture it and escape, though Xerxer was recovered by Y. During the final confrontation against Team Flare, Xerxer and Yveltal fought each other once more, while Lysandre used Zygarde to battle against Blaine, Mewtwo, and X. Meanwhile, Xerneas and Yveltal, knowing that Zygarde was only active due to their own activity alerting it to protect Kalos's ecosystem, chose to return to their dormant states. As a result, Zygarde then gradually disintegrated into small green blobs and disappeared.

Soon after the battle had ended, Blue and Blaine visited Professor Sycamore and mentioned to him about seeing a little green silhouette after Zygarde disintegrated into the blobs. Sycamore revealed to them that such green silhouettes, which he dubbed as Zygarde Cells, had also been spotted in the distant region of Alola, and sent Dexio and Sina to investigate them.

Sun, Moon, Ultra Sun & Ultra Moon arc

In Alola, Dexio and Sina hired Sun into collecting Zygarde Cells with the Zygarde Cube. During the climax of the arc, the Cells and Cores collected by Sun used the Reassembly Unit on Route 16 to combine to form Zygarde Complete Forme, which assisted Solgaleo and Lunala in the final battle against Ultra Necrozma on Mount Lanakila.

Trivia

  • Despite no longer being mandatory story catches, Xerneas and Yveltal have not had their catch rates reduced to the standard 3.
  • Each member of the trio has unique distinctions from each other:
  • Xerneas and Yveltal are the only game mascots to not be available or transferrable in Pokémon Scarlet and Violet. This is likely due to appearing in Pokémon Legends: Z-A.
  • Collectively, the trio may represent the Hindu Trimurti, with Xerneas representing Brahma, the god of creation, Yveltal representing Shiva, the god of destruction, and Zygarde representing Vishnu, the god of preservation. Notably, Vishnu is known for taking several different forms while carrying out his job maintaining balance in the world, similar to Zygarde.
  • The Legendary Pokémon have inconsistent terminology usage:
