Fairy tale bullies (5)
I believe the answer is:
ogres
'fairy tale bullies' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ogres that I've seen before include "Fairytale giants" , "Formidable people" , "Monstrous giants and man-eaters" , "'Monsters, fiends (5)'" , "She-giant of fairy tale" .)
