Ho-oh is only obtainable in Pokemon Diamond and Pearl by migrating it from 3rd Generation. To get it in 3rd Generation, you have to clear Mt.Battle in Colosseum or get it from a Nintendo Event.
yes its called migrating but in order to get your old Pokemon to get on your diamond you must first see all the Pokemon on diamond and peal. ounce you have all the Pokemon from d and p you have to put in your old gba game in the slot and at the start screen you will have the option to migrate the Pokemon. (you must have a original ds or a ds lite because the dsi does not have a gba slot)Jay1997 here. If u have ralts on a Pokemon diamond/pearl game, and not on another, then u don't need the national dex, just do a normal tradeI agree with Jay on this topic. i had a blaziken in my diamond version that had beat the game, and i traded it to my diamond version that hadn't beat the game yet, and all was fine
You can transfer it from an old Pokemon game (such as Pokemon fire red) or trade other people.
