One tough guy amid the many (2-3)
I believe the answer is:
he-man
'one tough guy' is the definition.
(I've seen this before)
'amid the many' is the wordplay.
'amid' indicates the answer is hidden within the clue.
'HE-MAN' is hidden within 'the many'.
(Other definitions for he-man that I've seen before include "Masterful male, macho sort" , "Extremely virile male" , "Muscular fellow" , "Macho type" , "Macho chap" .)
