"The Natural" protagonist Hobbs (3)
I believe the answer is:
roy
'the natural protagonist hobbs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roy that I've seen before include "'Rob ..., ... Rogers (3)'" , "Rob . . . was a famous Scottish outlaw" , "Man" , "'... Rogers, old film star cowboy (3)'" , "Rob . . . was a notorious Scottish outlaw" .)
