It is manaphy.
The last Pokemon in the sinnoh dex is Giratina, and the last one in the national dex is Manaphy.
Garatina...
cyndaquil
Last time I checked, only in Emerald did you have to capture every Pokemon for the PokeDex to be complete.
First Sinnoh theme: Diamond and Pearl Second Sinnoh theme: DP Galactic Battle Third Sinnoh theme: DP Battle Dimension Last Sinnoh theme: DP Sinnoh League Victors
if you meen the national dex then you need to find every Pokemon in the sinnoh pokedex
I think its when ash is don at the Sinnoh region and goes back to pallet
go to mt. corenet just pretend your going to spear pillar and just use that path and you sure will find one!
It may be riolu, which you can obtain only in an egg on Iron Island. __________________________________ no the last one is giratina. if you have the national pokedex then the last one is an arceus! they're AWESOME!
pikachu, staraptor, gible, torterra, monferno and floatzel
I don't know about latest, but last in national Dex is #493 Arceus, Sinnoh it's #150 Palkia and #151 Manaphy.
He is in Sandgem Town, in the Pokemon Lab after you see all the Sinnoh Region Pokemon. He will present you with the National Pokedex. After your pokedex is complete (note: you do not need to own all the pokemon) visit Professor Rowan. Professor Oak will come and give you the National Pokedex. After, he's in Pal Park, which is at the end of route 211. You'll see him there, then he'll leave. After that, he's in the last house to the left in Eterna City.
