"Romeo and Juliet" character (6)
I believe the answer is:
tybalt
'romeo and juliet character' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tybalt that I've seen before include "Killer of Mercutio (R&J)" , "killer of Montague" , "He hates, fights, Romeo" , "Capulet's duelling kinsman" .)
