Tao trio

The Tao trio is a collective fan term used to refer to the three powerful Legendary Pokémon of the Unova Region:, , and. Other fan terms include Tao dragon trio and energy trio. According to Unova myths, the Legendary trio was created during the war plaguing the region.

Much like members of other Legendary trios, the three Pokémon have similar appearances. Each has Dragon as their primary type. Both Reshiram and Zekrom have a base stat total of 680 while Kyurem's is 660 in its standard form—however, both White Kyurem and Black Kyurem have a base stat total of 700.

Each of the members of the trio has control of their own types and sides. Reshiram represents the concept of and controls Fire, Zekrom represents the concept of  and controls Thunder, and Kyurem represents the concept of  (the absence of yin and yang) and controls Ice; in its alternate forms it can also control Reshiram's fire and Zekrom's thunder to some extent.

Myths
The mythologies of the trio are implied to be connected, despite having no true relation. The origins of Zekrom and Reshiram are told in legends, as they were once a single powerful Dragon Pokémon used by twin heroes in order to create the Unova region. But the brothers each sought something different in life—truth for the older brother and ideals for the younger—and they began to argue, then fight, over whose side was right. The single dragon, in response, split into two Pokémon: Reshiram, who sided with the older twin, and Zekrom, who sided with the younger twin.

The two dragons were equally matched as they battled and neither conquered the other. As a result, the brothers set aside their differences and equally declared that there was no right side, either. But the sons of the heroes resumed the fight, and Reshiram and Zekrom destroyed the region with their fire and lightning powers. They subsequently disappeared afterward.

At the beginning of, one of them resides in Dragonspiral Tower, who is called upon by N to create his ideal world. The undefined is tasked with finding the other dragon in its corresponding stone (Light Stone in Black and Dark Stone in White) and revive it to resolve the history the twins began in the past.

Kyurem's origins were believed to be much different than those of the other two. The third dragon came down to the Pokémon world from an icy meteor and crashed into a place called Giant Chasm. The fact that Star Pieces, Comet Shards and extraterrestrial Pokémon can be found in the Giant Chasm strongly support this theory. An old legend in Lacunosa Town describing Kyurem claims that it would take people and Pokémon away from the town and eat them; this is why the town is now surrounded by a giant wall, and why none of its residents set foot outside their homes after dark. During however, an NPC claims that this story of Kyurem's origin might not be totally true. Professor Juniper theorized that the meteorite from the story could have been a Dragon Stone, similar to the ones that Reshiram and Zekrom were revived from. However, Drayden tells the player character of an old legend that tells a conflicting story of Kyurem's origins. The legend says that when the original dragon split into Reshiram and Zekrom, a third dragon was "created" from the leftovers: Kyurem. The Pokédex entry for Kyurem also states that it is waiting for a hero to fill in the missing parts of its body with "truth or ideals". This is completed in-game with the creation of its alternate forms, White Kyurem and Black Kyurem, created by Kyurem fusing with Reshiram or Zekrom (but not both).

In the anime
The Legend of Reshiram was a story told by Cedric Juniper and in Ash and N: A Clash of Ideals!. It comes from the White Chapter of Pokémon Mythology.
 * When a person appears who is searching deeply for the truth, Reshiram will appear. At first, Reshiram will battle with that person as a test of their strength and heart. And if it decides that person is a hero, it will pass on the wisdom it has accumulated over thousands of years and then bare it fangs against the hero's enemies. From that point on, Reshiram will treat the hero with kindness, as a parent would treat a child. But although the person called the hero will be able to attain great riches and power, the goodness in their heart will be lost, and the country built by the hero will be consumed in flames. Then, Reshiram will depart.

The Legend of the Hero was a story told by Cedric Juniper in Explorers of the Hero's Ruin!. It comes from Section Eighteen of the Chapter of Darkness in Pokémon Mythology.
 * When the hero turns darkness into light and the hero's heart becomes one with the Pokémon, Zekrom shall descend and lend the hero his power.

Kyurem accepts Keldeo's challenge, but proves far too great a match for the young Pokémon to handle, and it gained massive advantage. When Terrakion interfered to protect Keldeo, Kyurem froze it, along with Cobalion and Virizion in ice. Keldeo then escaped and took refuge on the top of a train. Kyurem, refusing to let the battle end unfairly, doggedly pursued Keldeo.

It was successfully awakened at the Dragonspiral Tower by, who was given the Dark Stone that the Shadow Triad successfully stole from the Nacrene Museum. N eventually convinced Zekrom to join his cause, making him the Hero of Ideals, and proceeded to another location to challenge Alder.

At around the same time that Zekrom was awakened, Brycen consulted with Drayden about the Light Stone, which Team Plasma were unaware of, that was also being stored at the museum. Brycen agreed to train and entrust him with the Light Stone. After completing the training course under Brycen, Black failed an initial attempt to summon Reshiram. In the middle of the battle between N and Alder, which Black came to witness, Reshiram made another attempt to emerge from the Light Stone, however Zekrom's roar forced it back in. It wasn't until Black became fully aware of Team Plasma's intentions, during the Unova League tournament, that he finally summoned Reshiram and became the Hero of Truth. Black eventually squared up against N, pitting Reshiram and Zekrom against each other, and Reshiram emerged victorious.
