There wasn't evidence that Ho-oh did so. Instead the evidence was towards Arceus, that shaped the world with 1,000 arms as the legend in Sinnoh told. (According to a Pokedex entry in Pokemon Diamond.) Arceus created all the Pokemon in the world; this included legendaries as well.
You fill up your pokedex then you will get national dex and all of battle island is opend and also you get to catch the other legendaires
you save before you fight and if you kill it just turn it off and back on
you have to catch all of the pokemon in diamond or SEE all of the pokemon
no legendaires cant have eggs exept for event eggs because they have no gender.
if you mean gain them, you cant, if you man get them on to battle revolution, just copy Pokemon with you d/p game with legendary Pokemon in a box or your party.
The only way you can see all the Pokemon on diamond is by going into the GTS and global trade different Pokemon.

no. you have to beat Pokemon ruby sapphire emerald fire-red or leaf-green. And if you have Pokemon diamond pearl or platinum, you have to beat the game and get all Pokemon in your pokedex. when you see all sinnoh Pokemon, you get a national pokedex.go to sandgem town, surf in the water and walk to the eastern part of the land to get to pal park. when there, save the game and turn off power. make sure that you have the gameboy game and the ds game in both slots and that they're working. when you press start on Pokemon diamond's main screen, go down to migrate Pokemon from which gameboy game you have, (ruby, sapphire, emerald, fire-red or leaf-green)and pick the six Pokemon you want to migrate to the ds game. after you pick all six, open your game file from where you were and talk to the worker to participate in the catching show. trust me.
