Creepy pic... Or I least I tried XD
Gastly has some mysterious powers. We all know that. It's because he is a ghost Pokemon. So he wanders/floats at a Pokmongraveyard. And he comes across the grave of Pichu! He starts using his creepy powers. And he lifts the soul of Pichu out of it's grave. That poor Pichu...

I tried my best to make this look dark. So it would look as if Gastly appears out of the dark. Out of nowhere. ^^
Let me hear you what you think =D
