God starts to create really awful, terrifyingly rich man (9)
I believe the answer is:
plutocrat
'rich man' is the definition.
(thesaurus)
'god starts to create really awful terrifyingly' is the wordplay.
'god' becomes 'pluto' (Pluto is an example**).
'starts to' says to take the initial letters.
The first letters of 'create really awful terrifyingly' is 'crat'.
'pluto'+'crat'='PLUTOCRAT'
(Other definitions for plutocrat that I've seen before include "One who's power derives from wealth" , "Capitalist" , "Magnate" , "Rich, influential person" , "Dives" .)
