Jungle hero (6)
I believe the answer is:
tarzan
'jungle hero' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tarzan that I've seen before include "Strong and agile man" , "Lord of the Jungle" , "Fictional hero raised by apes" , "Earl of Greystoke" , "John Clayton, Lord Greystoke" .)
