The Lake Guardians, or Lake Trio as they may sometimes be called, consist of the Legendary Pokemon Uxie, Mesprit, and Azelf, who reside in the lakes of the Sinnoh region. The Lake Guardians were based on wisdom, benevolence, and valor. These were given to the world upon the existence of the Lake Guardians.

According to the Pokedex entry for Azelf, the Lake Guardians were all hatched from a single egg. Upon being born, Uxie, Mesprit, and Azelf dove into the lakes of Sinnoh to reside in the caves located at the bottom. Unlike the legendary trios before them, the Lake Guardians are all of the same type: Psychic.

Also known as the Cloud Trio or Legendary Genies, the Forces of Nature is a trio of the male Pokemon Tornadus, Thundurus, and Landorus. All three Pokemon are Flying-types, but Thundurus is also an Electric-type, while Landorus is a Ground-type. The Forces of Nature were created based on different Kami in Japanese mythology. They were created with the image of a magatama in mind. They can use the Reveal Glass to change to their Therian Formes.

Many moons ago, Tornadus and Thundurus were tormenting the people of the land by creating thunderstorms and strong winds with their power. The people were fearful of the danger that they caused. As such, Landorus put a stop to the antics of Tornadus and Thundurus, and punished them.

Lugia is a Pokemon with a strong resemblance to birds and dragons. It resides in the sea and is said to be the guardian of the seas. Lugia and Ho-Oh make up what is known as the Tower Duo. Lugia once roosted upon the Brass Tower while Ho-Oh the Bell Tower, but the Brass Tower was destroyed in a fire caused when lightning struck it.

Lugia is the trio master of the Legendary Birds of Gen I: Moltres, Zapdos, and Articuno. When the Legendary Birds are awakened, Lugia is the only one capable to stop the bickering between the Legendary Birds. Due to its incredible power and ability to cause destruction, Lugia hid itself away at the bottom of the sea.

Mew is a Psychic-type Pokemon that was first revealed in Pokemon: The First Movie - Mewtwo Strikes Back. Mew’s DNA was used to clone Mewtwo. According to the Japanese version of the movie, Mew’s intent was to destroy cloned Pokemon for they were inferior to real Pokemon, to contrast the antagonist, Mewtwo.

At one point, millions of years before the start of what we know as the Pokemon world, Mew were said to be plentiful, however there are very few Mew in existence now, although Ash has come across a Mew from time to time. Mew are said to be one of the first Pokemon in creation. It is said that Mew’s DNA contains the genetic code for all Pokemon in existence. Some believe that Mew is the ancestor of all in the Pokemon world, so all living beings can trace their origins back to Mew, including people.

The creation trio refers to Dialga, Palkia, and Giratina, the three legendary Pokemon from the Sinnoh region. The creation trio are ruled by Arceus and were created by Arceus upon creating the Pokemon world. Each one of the Pokemon is a Dragon-type. They also all have the ability Pressure and hidden ability Telepathy.

Dialga was given power over time, Palkia space, and Giratina antimatter. Arceus had given each Pokemon command over their own dominions, but it was Giratina who was actually given Distortion World where time and space are distorted.

Deoxys is a Psychic-type Pokemon with four different Formes. The Forme used to depend on which cartridge the Pokemon was on, but now can be changed in certain towns at will. The Formes each focus on a different stat. Deoxys can change the shape of its hands from ribbon-like forms to hands. It is one of the few Pokemon that we get to see from space.

It is said that Deoxys is a virus from space that had mutated to create what we now know as Deoxys. In the center of Deoxys’ chest is a crystalline organ that is said to operate as its brain and is used to shoot lasers. Deoxys is capable of regenerating body parts lost in battle and cloning itself, as seen in the anime and manga.

The Tao Trio consists of Legendary Pokemon Reshiram, Zekrom, and Kyurem. All three of them are Dragon-type Pokémon. Reshiram has power over Fire, Zekrom Thunder, and Kyurem Ice. Kyurem is somewhat capable of controlling Reshiram’s Fire and Zekrom’s Thunder in its alternate forms.

It is said that twin brothers of the Unova Region used a single Dragon Pokemon to create the Unova region. Unfortunately, they did not agree on ideals in life, so the single Dragon Pokemon was divided into Reshiram and Zekrom. While the brothers could not agree, their Pokemon were so evenly matched that they resigned that no point was more important than the other. However, the fighting continued with their sons wreaking havoc on the Unova region. Kyurem was said to have crashed into the Giant Chasm as an icy meteor, although Drayden believes that Kyurem was created from the leftovers when Reshiram and Zekrom separated. Lacunosa Town is walled because in legends, Kyurem would devour people and Pokemon alike from Lacunosa Town.

Also, less commonly referred to as the elemental trio, the weather trio refers to the three legendary Pokemon in Third Gen: Kyogre, Groudon, and Rayquaza whose abilities allowed them to control weather. Kyogre was created in underwater trenches by the intense pressure. Groudon by the magma and earth. Rayquaza was created out of minerals found in the ozone.

According to the legends, Kyogre and Groudon fought violently over the energy that was overflowing the Earth. The people were plagued by the constant fighting and so, the Draconid people wished upon a meteor at the Meteor Falls for Rayquaza to quell the fighting, sending Groudon and Kyogre into a deep slumber. However, a meteor struck Sootopolis a millennium later, waking the legendary beasts and reigniting their rivalry. The Lorekeeper of the Draconid people used a rainbow stone to wish for the return of their savior, Rayquaza. Rayquaza was able to quell the fighting yet again by becoming the first Pokémon to Mega Evolve. Then the Draconid people have built the Sky Pillar to be a place where they can once again summon Rayquaza in a thousand years, when it was foretold the beasts would awaken again.

Ho-Oh is known as the guardian of the skies and the master of the Legendary Beasts in Generation II. Lugia and Ho-Oh both make up the Tower Duo. Ho-Oh is said to be able to resurrect the dead, and should you be one of the few to see it, you will be granted neverending happiness. When Ho-Oh flies, the light shines through its wings creating a rainbow trail.

Ho-Oh once roosted in the Bell Tower, while Lugia the Brass Tower. One day, lightning struck the tower that Lugia roosted upon setting the structure ablaze and killing three Pokémon. Ho-Oh used its powers to revive those three Pokémon who became the Legendary Beasts, said to represent the powers involved in the accident: the fire that engulfed Brass Tower, the lightning that started it all, and the rain that doused the fire. Legend dictates that Ho-Oh will return when a Trainer arrives with the power to touch Pokémon souls.

Arceus is a Normal-type Pokémon capable of changing types when holding a plate. Arceus is genderless and is not in any regional Pokedex, so it does not have a Pokedex number other than its National Pokedex number. According to the legends, Arceus has 1,000 arms that it used to create the world.

According to the Pokedex, Arceus had been born from an egg into a world of nothingness. From there, Arceus created the legendary Pokemon: Dialga, Palkia, Giratina, Uxie, Mesprit, and Azelf, becoming the master of both trios. These trios helped to shape the world, but it was Arceus who gave birth to the rest of Pokémon-kind. After the Sinnoh region was formed, Arceus created the three Orbs: Adamant, Lustrous, and Griseous. It was then that Arceus felt its work was done and began its deep slumber. Ultimately, Arceus was the god of the Pokémon world.
