Legendary figure making comeback? (4)
I believe the answer is:
echo
I believe this is a double definition.
'legendary figure' is the first definition.
(mythological woman)
'comeback?' is the second definition.
(thesaurus)
'making' acts as a link.
(Other definitions for echo that I've seen before include "repeated answer" , "Greek girl in love with Narcissus" , "Nymph whose love Narcissus spurned" , "Marked by heat" , "Reflection of sound waves" .)
