Legendaries

Legendary Elementals are a special kind of Elementals that each have a unique species that appears only once every reincarnation. There are different kinds: gods, legendary and mystical Elementals.

Gods
The gods of this world are Arceus, Giratina, Dialga and Palkia. They are, technically, immortal.

Arceus is the mother of everything and older as time itself. They have the power of creation. Not much is known about Arceus itself, as the story of creation only gives a vague picture of who Arceus used to be.

Giratina was the first being Arceus created. With her creation and immense power, a second world came into existence as well: The Distortion World. She could travel between both worlds and had the strongest powers of all Ghost type elementals until she gave pieces of her broken heart away, creating witches in the progress. If she gets killed she will be reborn in the Distortion World and can only change dimensions again if someone summons her.

Legendary Elementals
Legendary Elementals are a group of Elementals who are seen as mortal deities and have great magical abilities, no matter their type. Whenever they die, a few years later a reincarnation with no memories of their past life is born again. Being born as a legendary elemental comes with many obligations, something hard to follow for a few of them.

Ho-Oh
Lugia is one of the two reincarnations always born in New Johto since the country itself was left behind by its inhabitants. The legendary flying-type Elemental is said to represent the rainbow, which is why their hair glistens in rainbow color whenever hit by light.

Lugia
Lugia is one of the two reincarnations always born in New Johto since the country itself was left behind by its inhabitants. They are known to be able to destroy whole cities with a single beat of their wings, something that's kept under control with cutting them off with a curse.

Together with Ho-Oh both are supposed to pray for saftey of the country each week at the Bell and Brass Towers to make sure New Johto doesn't meet the same fate as Johto itself.

Groudon
Groudon is one of the three legendary Elementals of Hoenn. Known as the deity of earth, he can cause major earthquakes and crevices.

Kyogre
Kyogre is one of the three legendary Elementals of Hoenn. As the deity of water they have destructive powers: they can cause floods, rainy thunderstorms and tsunamis.

Groudon and Kyogre are born at the same time and share a deep bond, which leads them to either fight to death and destroy the land or be fated lovers. If one of them dies, the other one dies as well. To avoid conflict both are taught to never use their magic, no matter how bad the situation might be.
