Pokémon Diamond and Pearl/Un-Obtainable Pokémon

You CANNOT catch any of the Pokémon that are not in the Sinnoh Pokédex until you acquire the National Pokédex. You must SEE all 150 Sinnoh Pokémon. Once you do so, you must visit Prof. Rowan in Sandgem Town. When you talk to him, Prof. Oak will rush in and upgrade your Pokédex to the NationalDex. Once he does so, you can import any Pokémon from FireRed, LeafGreen, Ruby, Sapphire, and Emerald, by putting that game in the DS's GBA slot and selecting the TRANSFER option at the Diamond/Pearl Main Menu. Once you transfer Pokémon from the GBA games, they will be gone forever from the GBA games. After you transfer Pokémon to Diamond/Pearl, you must then capture them in the Pal Park**.


 * To see, (in Pearl) or , (in Diamond), you must speak with the Elder of Celestic Town (the old lady in the big house.) She will then show you a picture of Dialga/Palkia, adding the 150th Pokémon to the Sinnoh Pokédex.

(NOTE: The Route #'s must be confirmed, it is believed that they are Route 211[Water] and Route 212[Land])
 * ** The Pal Park is directly south of Sandgem Town. Go to Sandgem Beach and Surf to the area near the Pal Park.

Pokémon that cannot be obtained in Sinnoh
Some Pokémon cannot be obtained in Sinnoh. These Pokémon must be transferred from either Pokémon FireRed, Pokémon LeafGreen, Pokémon Ruby, Pokémon Sapphire, or Pokémon Emerald via Pal Park. These Pokémon are listed below.

Pokémon that cannot be obtained without using the Underground
Some Pokémon can only be obtained by going into the underground and doing various things.

Fossils
Fossils can be found while digging into the Underground and can be brought to Oreburgh City's Mining Museum for revival. The Armor Fossil can be found in the Pearl version and the Skull Fossil  can be found in the Diamond version. The rest of the fossils can be found after you obtain the National Pokedex and can be found in both versions. These include the Dome Fossil, the Helix Fossil , the Root Fossil , the Claw Fossil , and Old Amber. Multiple versions of each fossil can be found and revived.

Spiritomb
There are special conditions in the underground that must be met to get a Spiritomb. First, you must obtain the Odd Keystone by digging around and then you must meet 32 people underground.

Evolution Stones
Many Kanto and Johto Pokémon are evolved with stones. In the main quest of Diamond and Pearl you only find a few of these stones, more can be found in the Underground. As a result some Pokémon won't evolve until you get the stones from the underground.

The only way to obtain Manaphy is to own a copy of Pokémon Ranger and have completed the game and completed the Manaphy egg mission. Once you have the Manaphy egg on Pokémon Ranger, you can now transfer it over to Diamond and Pearl. Once transferred over to Diamond and Pearl, visit any Pokémart to receive the egg from a man wearing green.

Phione can only be obtained once Manaphy is gotten. Although Manaphy has egg groups, it is genderless; to obtain Phione, Manaphy must be bred with a. Phione learns almost all the same moves as Manaphy, but has lower statistics.

Through a Nintendo Event, the player will be able to receive a Member's Card from the same man Manaphy is obtained from. Then, go inside the locked building in Canalave City. Note that you must heal the sick boy before you can do so. A man will tell you that you have a reservation, and you will be forced to sleep on the bed, and wake up on Newmoon Island. At this point, you cannot get off. Walk into the center of the island to meet Darkrai. Alternatively, Darkrai can be obtained in the Japanese versions of the game by using a glitch involving the move Surf inside the Elite Four.

Through another Nintendo Event, you will get a Prof. Oak's letter. Go to Route 224 to find Professor Oak standing at the white rock at the end. He will tell you to give your thanks to someone. Doing so will make Shaymin come, and upon seeing you, run. Chase after it, going along the road until to meet it. Shaymin can also be caught with the surf glitch

Through another Nintendo Event, you will get an Azure Flute. Go back to the Spear Pillar. Upon walking on the first symbol on the floor, an option to play it will appear. If you say yes, stairs leading upward to the Hall of Origin will appear. At the top is Arceus.
