Dun, dun DUN! Here it is! THIS is what the Ogawa Pokedex would be for.
New features would include:
-More than 60 new species of Pokemon (I decided to go for 10 more than the 58 I had originally planned)
-Special Olympic Contest-esque minigames for starter Pokemon from all generations.
-Hybrid Pokemon, only obtainable though special breeding techniques.
-A Colosseum Mode, for battling with random trainers online from around the world (no Friend Codes required).
-For the first time in more than 7 years, the entire Johto region would be available for exploration after defeating the Ogawa Elite Four.
And finally, all 561 Pokemon would be obtainable between the 2 games: Kanto Starters would be obtainable through in-game trades; a choice of one Johto Starter would be the reward for completion of the Ogawa Dex; one egg for each of the Hoenn Starters would be hidden in the Ogawa region; a choice of one Sinnoh Starter would be the reward for defeating the Johto League Champion; Lugia and Ho-Oh would be catchable in Johto; one of any other Legendaries could be obtained though evolving Karope; all other Pokemon would appear in the Ogawa Dex or in swarms.
And the bios for the respective Legendaries:
Species: Day Pokemon
Weight: 330 lb.
Description: Achiro is ruler of the day & the master of Uxie, Mesprit, and Azelf. It is equally at home underwater and in the skies, but will only appear in the latter in times of peace. It's constant power struggle with Ekuvile ensures that the balance between day and night will be maintained. However, if Achiro fails, then eternal night will engulf the planet, causing plants to wither and all life to fade away.
Species: Night Pokemon
Weight: 1010 lb.
Description: Ekuvile is ruler of the night and the master of Teslatu, Pyroyo, and Cryonos. Many humans falsely believe this Pokemon to be an evil entity, but the truth of the matter is that if Ekuvile did not keep Achiro's power in check, day would overtake night and chaos would ensue. The sleep patterns of wild Pokemon would be disturbed, the oceans would evaporate, and the planet would be roasted alive.
