Thx for the above answer, but when you say everyone does that include in all the buildings and pokemarts? I'm not sure if this answer is old or not, but it would help me if you could answer this. Today is 4/4/11.
No you cant unless you have cheats
Im afraid you cant.Deoxys an only be obtained by migrating or using a cheat device(gameshark,action replay ect.)
Trading, migrating from LeafGreen or FireRed, or cheats.
you can get mew and mewtwo by migrating it from Pokemon fire/green
u hav to find all of the Pokemon in the national pokedex
You cannot get a Mewtwo in Platinum.
Yes by migrating it from firered or leafgreen.
counting cheats its 34 without cheats 22
there are a ton of cheats for Pokemon games but i can't figure some out. : (
you cant get every legendary of Pokemon without cheats or migrating and trading with people
Ho-Oh can't be found on Platinum. The legendaries of Articuno, Moltres, and Zapdos can be found though.
without cheats you would have to migrate
