You have to catch it

FireRed LeafGreen transfers to Ruby/Sapphire. Transfer Pokemon from Ruby/Sapphire (and the transferred FireRed LeafGreen Pokemon) into Diamond via Pal Park. Also you need transfers from Pearl and/or Platinum. Maybe SoulSilver and SoulGold too? Alternate method: Action Replay device.
look in your pokedex
Ledian
yes you can they are both the same game.emerald can trade with Sapphire ruby emerald firered leafgreen and that's its. the trick that u can do is migrate your Pokemon from firered leafgreen Sapphire ruby and emerald to fill up your national pokedex in Pokemon diamond, pearl, platinum,heartgold, and soulsilver. U MUST have a ds or ds lite
Johto Pokedex: 256 National Pokedex: 493
Yes, If you read the manual that came with the game(Pearl or diamond) It said you have to complete your pokedex then go to a garden and you can catch all the Pokemon you export.
No, there is not a Pokedex after the National Pokedex in Pokemon Diamond Version.
If You Have Firered or Leafgreen and choose charmander as a starter capture 60 pokemon If you Have all The Pokemon in the Pokedex you'll Get it in a 4th generation game like pokemon diamond pearl and platinum you will get the national dex after you defeat the champion
diamond pokedex number 80 is Barboach
No it isn't cheating because that's how you complete your Pokedex in Pearl/Diamond/Platnium.
Try to go after the rare Pokemon and the rest of your pokedex. If you did that, then start a new game or migrate to Diamond, Pearl, or Platium, or grow all Pokemon to a lv. 100.
