Destroyer has wrecked about four (5)
I believe the answer is:
shiva
'destroyer' is the definition.
(Shiva is the destroyer in Hinduism)
'has wrecked about four' is the wordplay.
'wrecked' indicates an anagram.
'about' is an insertion indicator.
'four' becomes 'IV' (Roman numerals for four).
'has' with letters rearranged gives 'sha'.
'sha' going around 'iv' is 'SHIVA'.
(Other definitions for shiva that I've seen before include "God presiding over personal destinies" , "Hindu god, the destroyer" , "Major Hindu deity (the destroyer)" , "Jewish period of mourning" , "powerful deity" .)
