2. World Heavyweight Champion
As it stands, when he retires, Mark Henry will have only two Championships under his belt, that were recognized as true world titles- the ECW Championship and the WWE World Heavyweight Championship. Of course, he also held the European Championship as well, but of all of the mentioned title reigns, the WWE World Heavyweight Championship reign will undoubtedly be his biggest achievement.
Mark defeated Randy Orton at the 2011 Night of Champions pay-per-view, to capture the World Heavyweight Championship. Mark became the first African-American to win this title during his 15 years with the company, at this particular time. He also became the fifth African-American in history, to win the World Heavyweight Title overall.
