Which Fairy Tale character do you think Dr. Whale is? I do not think it has said in the show.

I have no idea but I think the blue fairy does

I know everybody wants to guess Monstro but I actually think he might be the Frog Prince (Not the Disney verision though). Could explain his womanizing nature. Also, apparently in that story the Prince was cursed by a fairy and he was hanging around the Blue Fairy's character in the finale quite a bit so who knows.

I think he might be Monstro. Judging by that he's always around the Blue Fairy and the Blue Fairy had to save Pinocchio from Monstro. Also Dr. Whale is always seeming to be "swallowed up" by the problems surrounding him. Maybe Dr. Whale was like Jiminy Cricket before Jiminy was a cricket. A sudden transformation might have occurred. Dr. Whale is also a bit of a lech so maybe he could be male siren sort of creature. I don't know if that makes any sense. He could be also Captain Ahab from Moby Dick. Captain Ahab was always after the famed white whale. Dr. Whale wears all white in case anyone hasn't noticed. Maybe he's not Monstro or Captain Ahab. Maybe he's Moby Dick. He's a very shadowy figure; lurking in the dark ready to appear out of nowhere.
