Omnipotent in general (7)
I believe the answer is:
overall
This clue is a double definition.
'omnipotent' is the first definition.
(I've seen this before)
'in general' is the second definition.
(I've seen this before)
(Other definitions for overall that I've seen before include "protector" , "on average" , "Taking account of all the factors" , "blanket" , "Protective clothing" .)
