Fairy tale beast (4)
I believe the answer is:
ogre
'fairy tale beast' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ogre that I've seen before include "Fairy tale monster" , "man-eater" , "Cruel, fearsome person" , "Man-eating monster of fairy tales" , "character in 'Puss in Boots'" .)
