"Puss in Boots" baddie (4)
I believe the answer is:
ogre
'puss in boots 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 "'Demon, fiend (4)'" , "Ergo (anag.)" , "character in 'Puss in Boots'" , "Fierce giant" , "Grim(m) beast?" .)
