First, a run-down of the particulars:
- Inception of the championship occured on 10/14/1993, the first “top contender” match-up that took place within this division.
- Vacancies after inactivity periods were fulfilled by the next “top contender” match. Absence of such, was not a problem at Heavyweight.
Your current lineal Heavyweight champion is Alistair Overeem
The full history is below. Note, the colored backgrounds indicate a title change.
