ummmmmmmmmmm dude i dont think he goes anywhere just u cant see him anymore
If you have Fire Red in your DS, go to the Old Chateu.
go to the tv in the old chateu at night ant you will find rotom
Gengar is a powerful ghost type of Pokemon. In Pokemon Platinum it is possible to capture one by going to the Old Chateau.
you find it in the ghost house near eterna at night in the t.v.
you find him in the old chateu in the ilex forest
go to the old chateu and have a gba game in the ds (only works on ds and dsl) go to the room with the blinking eyes and search for ages. it works
You go to the old chateu in eterna forest and go inside. . . you'll only find Gastly. It can be effective when trying to cath Azelf where if it uses uproar its harder to catch YW...
buy the Pokemon platinum book
get the national pokedex and go to the Eterna forset and right in front of the old chateu is a gym leader saying she is not scared. Then go inside and find a room with a T.V and press A and it would say a Pokemon want to come out. Press A rotom comes out.
The 151st Pokemon is Mew and is unobtainable in Pokemon Platinum.
no you can't find a torchic egg in Pokemon platinum
If you want to see an old man with a ghost Pokemon because you need to see a ghost Pokemon for your pokedex, well, there's a gym leader with 3. If you need to see this PARTICULAR GUY, then (wait, first I don't know why because I've beaten Platinum without finding an old guy with a ghost Pokemon, but) go back to the places you've been and explore everywhere. The world is a big place. It might take some time.
