Bully; Trojan prince (6)
I believe the answer is:
hector
This clue is a double definition.
'bully' is the first definition.
(I know that bully can be written as hector)
'trojan prince' is the second definition.
(I've seen this in another clue)
(Other definitions for hector that I've seen before include "King's son" , "Trojan prince killed by Achilles in siege of Troy" , "Intimidate by bullying, or Greek warrior killed by Achilles" , "Bully (someone) verbally" , "Bully, intimidate or threaten" .)
