As a henchman for DIO, Hol Horse's confidence fluctuates significantly. Unlike many overconfident Stand users, Hol Horse is primarily aware of how weak his Stand, Emperor, is when compared to most Stands. This knowledge combined with his affable personality (since he has no problem being a second-in-command rather than a "Number 1") makes him willing to partner up with someone else. In that case, Hol Horse is very confident that he can take on anyone.
