Mew and mewtwo are part of the kanto pokedex not the hoenn pokedex but you do need these two to finish the entire pokedex.
You need to have the national pokedex, talk to Dawns sister a few times (she tells you were Pokemon that you can catch from hoen)
You need to get the National Pokedex.
you don't need to find him. what you need to do is get the national pokedex. by the way if you want to catch mewtwo it's on route 224! i think. well that's what some other person said. he or she said that it's one out of 2,000 chance or whatever. they said mewtwo is a HE. everybody knows mewtwo is an IT. just go get the national dex. anyway gotta go. my DIALGA is almost fainted.
To Catch Mewtwo You Need A Action Replay.
it's actually mewtwo to get mew you need to defeat the elite four 12 times after caching mew in cerualen cave if you need anyother answers just ask
You need to for the National Pokedex, but not the Sinnoh Pokedex.
In Pokemon Diamond and Pearl you need the National Pokedex to get Magnemite. In Pokemon Platinum you don't need the National Pokedex to get Magnemite.
you need 200 Pokemon to fill the whole pokedex
you need the national pokedex to get eevee
You do need the national pokedex for the Pokemon modifier. the Pokemon modifier uses the national pokedex numbes. you can not use the sinno pokedex.
No,you need to defeat the elite four first, then go to proffeser rowans lab and he will give you national pokedex.
No you do not need it.
