Fighter turns to drama (7)
I believe the answer is:
matador
'fighter' is the definition.
(matador is a kind of fighter)
'turns to drama' is the wordplay.
'turns' is an anagram indicator.
'to'+'drama'='todrama'
'todrama' is an anagram of 'MATADOR'.
(Other definitions for matador that I've seen before include "Bullfighter who slays the bull" , "ROM data (anag)" , "A Spanish bullfighter" , "Ring butcher" , "he aims to get a bull" .)
