Figure on being a hero (4)
I believe the answer is:
lion
This clue is a triple definition!
'figure' is the first definition.
(I have seen 'Important figure' mean 'lion' so perhaps 'figure' could also mean 'lion')
'on' is a link.
'being' is the second definition.
(lion is a kind of being)
'a hero' is the third definition.
(lion can mean a brave person)
(Other definitions for lion that I've seen before include "Simba, for example" , "cowardly character in Oz" , "Sought after celebrity (showing great strength and courage?)" , "Wild cat" , "Animal which Judah is described as" .)
