They are the villains from the videogames NiGHTS into Dreams and its sequel, NiGHTS Journey of Dreams. Reala is a nightmaren created by Wizeman who calls himself the god of Nightmare, the realm they both originate from. They're fantastic games.
Silly billy, I KNOW who they are (if I didn't who they are then how would I have fanart of them on my page?) I was asking what Pokemon you made them. Also I think you are mistaken when you said Wizeman came from Nightmare, in the NiGHTS into Dreams instruction manual it states that Wizeman is a visitor without his Ideya. ( I know 'cause I have both games and the manuals that go with them)
Oh sorry I didn't realise what you meant. Neither Reala or Wizeman are on there. I've got Clawz as a luxray, owl as a hoothoot, NiGHTS as an emolga, Helen as a pikachu, Jackle as a haunter and Puffy as a Wigglytuff. And ok, I didn't know that about Wizeman. Thanks for telling me.
