A universal god creator (6)
I believe the answer is:
author
'creator' is the definition.
(author is a kind of creator)
'a universal god' is the wordplay.
'universal' becomes 'u'.
'god' becomes 'thor' (Thor is an example**).
'a'+'u'+'thor'='AUTHOR'
(Other definitions for author that I've seen before include "Ford, for example" , "Creator of written work" , "Writer - initiator" , "Source, writer" , "Creative artist" .)
