Divorced legend's despicable character (4)
I believe the answer is:
heel
'divorced legend's despicable character' is the definition.
I can't tell whether this defines the answer.
'despicable character' is the wordplay.
'despicable' becomes 'h' (I can't explain this - if you can you should believe this answer much more).
'character' becomes 'eel' (I have seen 'Slippery character ' mean 'eel' so perhaps 'character' could also mean 'eel').
'h'+'eel'='HEEL'
(Other definitions for heel that I've seen before include "Instruction to a dog" , "Be inclined" , "afoot?" , "Rogue" , "Achilles' weak spot" .)
