Disney evil uncle (4)
I believe the answer is:
scar
'disney evil uncle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scar that I've seen before include "nine [AL CAPONE] had to face" , "Stain" , "Mark of healed cut" , "evidence of damage" , "Healed-cut mark" .)
