This topic started out in the CB by Monkey_Senior about a question on how to the "god Pokémon" breed? I went on to answer that because they are considered gods, they do no breed, they would just created lesser beings of themselves.
This then led to the mythology of Pokémon and how everything came to be.


Pokémon Timeline
*Timeline events are taken on all known information from the Pokémon games.
All were taken fro Pokémon Diamond and Pearl from the library in Canalave City.


The Original Story

"In the beginning, there was only a churning turmoil of chaos.
At the heart of chaos, where all things became one, appeared an Egg.
Having tumbled from the vortex, the Egg gave rise to the Original One.
From itself, two beings the Original One did make.
Time started to spin. Space began to expand.
From itself again, three living things the Original One did make.
The two beings wished, and from them, matter came to be.
The three living things wished, and from them, spirit came to be.
The world created, the Original One took to unyielding sleep..."

Begining of the universe
So, an Egg appeard out of the void
And hatched into the Original One, which is, of course, refering to Arceus.
Arceus then created two beings from itself, Dialga and Palkia
Dialga controls and then started time, while Palkia controls and then created Space.

Afterwards, Arceus then created from itself three more beings, Uxie, Mesprit and Azelf. Though all three are said to have hatched from the same egg.


Whereas Dailga and Palkia are in charge of Time and Space, the Lake Trio were created to bring knowledge (Uxie), emotion (Mesprit) and will-power (Azelf) to future generations of Pokémon.

It is interesting to note that Dailga and Palkia's footprints look like crowns. Dialga's looks like a king's crown, Palkia's looks like a queen's, and Giratina's is smaller than that, possibly a prince's, which leads to believe that Dailga and Palkia created Giratina. However, shortly after being created, Giratina disappears into an alternate dimension.



Creation of the Pokémon World
Uxie, Mesprit and Azelf then create Groudon and Kyogre, who are tasked with forming the land and the sea.


As the last line in the Original Story says, Arceus then falls into a deep sleep.

The world being created, Groudon and Kyogre then get into a ferocious battle and nearly destroy all that they have created. Uxie, Mesprit and Azelf intervine and create Rayquaza who banishes Groudon and Kyogre to hidden areas of the Hoenn region. Rayquaza is then tasked to watch over the skies.


Uxie, Mesprit and Azelf then focus back on the world. They create Regigigas who was tasked with moving all the continents that Groundon made into different land masses. One of these collosal movements creates the now Mt. Coronet in the Sinnoh region.



Prehistory
The world then starts new life, with the time now millions of years before Generation l.
The earliest known prehistoric Pokémon exist in this time with this information based primarily on fossils and archaeological remains such as Omanyte, Kabuto, Aerodactyl, Lileep, Anorith, Cranidos, Shieldon as well as their evolutions.


Additionally, Relicanth is also an ancient Pokémon and it can be considered a living fossil since it survived extinction for approximately a hundred million years and can be caught in the wild instead of being revived from a fossil.


About 10,000 years before Generation l, the legendary golems are then created by Regigigas in accordance with the world's different ages-

Stone Age: Regirock

Ice Age: Regice

Iron Age: Registeel

Presumably, after these Ages is when most Pokémon populations start to decline, more notebly Tangrowth, Mamoswine and Yanmega. By having Tangela, Piloswine and Yanma learn the move Ancient Power, they can each evolve to their once "ancient" nature.



1,500 years before Generation l is the earliest known date for the system of writing developed and used at the Ruins of Alph, Tanoby Ruins, and Solaceon Ruins. Archaeologists are currently unsure whether the nearly identical Unown preceded or succeeded the writing system, but it is assumed they share some sort of connection.




Recent History
c. 700 years before Generation l, the Brass and Tin Towers are constructed in Ecruteak City. At this point is when Lugia (Brass) and Ho-Oh (Tin) are perched at each respective tower's top.




c. 150 years before Generation l, the Brass tower burns to the ground, killing three Pokémon that were inside. From this point, it is now known as the Burned Tower. Lugia then flees to the Whirl Islands. It creates the legendary birds and then rests at the bottom of the sea. Ho-Oh resurrects the three fallen Pokémon as the legendary beasts and flies off in search of a pure-hearted Trainer.



Contemporary History
Years prior to Generation l, a hair is found belonging to Mew and Mewtwo is cloned from it.



Generation lll is when Team Magma and Team Aqua release Groudon and Kyogre from their banisment in order to take over the world. The hero is able to calm both legendary creatures though from doing any damage.




**There's still alot more to add but here is just the begining of it!**


CB conversation wss provided by Monkey_Senior, Bea and I with Norwegianboy listening in and throwing in a comment every now and then that had nothing to do with the topic lol.

Hey, I started the Regi part yesterday lol.

Oak I would be glad to help for more research.

That was realy AWSOME
I'd like 2 hear more of it
( now I get most of it )

this is very informative and very long

wow. good job oak.
this is what took u so long

so you can breed a suicine and a ditto and it works?

well Chimchar, i'm not sure if you played pokemon snap, or watch the T.V. show, but in Snap Legandary Birds hatched from Eggs, and Baby Lugia, Episode 223:English name "A Trapped Parent!" Japanize name "Captive Lugia" , appered in an episode of pokemon, so in theory, yes they could breed, but for some reson that theory has not applied to the "regular" pokemon games yet

Pokemon Snap Picture: <-----Zapdos hatching
Episode 223 Picure: <------baby Lugia, mom in episode, but i can't get a picture here, go to Serebii.net for proof

Monkey

Most of this relates to the t.v. show, not the game, but I may be wrong.

I think Lugia CAN breed because there might have been 2 Lugias. The one in the Whirl Islands and the one in the episode Monkey put. They might have done something so have the Baby Lugia.

If Lugia can breed, that means genderless pokemon are hermaphrodites

I'd imagine Legendaries can't breed ingame for balance reasons. You're supposed to be ridiculously lucky to even get a glimpse of these things. We not only get to catch them, we can catch all of them, with good natures!

There were three Lugias in the anime: the mother and baby, and the one in the movie. And RBY/FRLG seems to hint at a second Articuno. And Enteis are born when a volcano erupts (when Entei barks, I think). So there's evidence of whole populations of some Legendaries.
