Scary character (4)
I believe the answer is:
ogre
'scary character' 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 "Bugbear" , "Jack's giant perhaps" , "Cruel fairytale giant" , "Monstrous creature" , "Giant of folklore who liked to eat humans" .)
