I think he’s exactly the same
A bounty killer in GBU and FAFDM and in FOD he’s only interested in money,too.
I’ve read anywhere that in FOD a few words are spoken which says the opposite,but i’d say the money grubbing character was intended by Leone.
By the way Leone had the idea for a trilogy in his head,at least since he made GBU,which is the beginner for it.
In another topic,i can’t remember,the hints are explained very good.
The ‘Poncho’ thing for example,i guess it was Scherps - who else.
Of the three titles,which sounds far too American,no one have the vehemence of the Dollar titles in my opinion
