Fairy tale baddie (4)
I believe the answer is:
ogre
'fairy tale baddie' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ogre that I've seen before include "Terrifying person" , "Has a monstrous role" , "Man-eating monster of fairy tales" , "Giant of folklore who liked to eat humans" , "Evil giant" .)
