In combat manhandled masked superhero (6)
I believe the answer is:
batman
'masked superhero' is the definition.
(I've seen this in another clue)
'in combat manhandled' is the wordplay.
'in' says the answer is hidden in the clue.
'BATMAN' is hidden within 'combat manhandled'.
(Other definitions for batman that I've seen before include "Caped superhero" , "Comic/film superhero" , "Military servant" , "Officer's personal servant" , "Army servant - comic character" .)
