in victory road there is an ace trainer that you have to battle and she has a blissey
If you are talking about the Sinnoh Pokedex, the Pokemon is Unown. If it is in the National Pokedex, I have no idea. But it should be easy to find on one of those online pokedexes.
You can one either by trading, or by leveling up a Chansey
find a chansey south of Solaceon Town and train it to lvl 50
Well, You can't you have to migrate or if u have a gameshark or some codes to unlock it.
Unown is number 114 in diamond pokedex hope it helped
No, there is not a Pokedex after the National Pokedex in Pokemon Diamond Version.
diamond pokedex number 80 is Barboach
press switch pokedex on the national pokedex and you will be using the sinnoh pokedex
Well, since there is no number 117 in the local pokedex in Pokemon Diamond, we have to look into the national pokedex. In the national pokedex, number 117 is Seadra. Number 117 in the Sinnoh Pokedex is Wooper, can be found in the great marsh or on route 212
There is no other pokedex.
vfrt in the pokedex for sinnoh #111 in the pokedex is a garchomp
There is no way you have to compleate the pokedex but most of it is at the gyms.
