10 Biggest WWE Superstars Never To Headline WrestleMania

8. The Iron Sheik

The go-to main event of many early 'Manias was Hulk Hogan vs whichever cartoonish villain was flavour of the month - usually a brute like King Kong Bundy and Andre, or a heel with anti-American ideologies, such as Sgt. Slaughter and Yokozuna. It therefore may come as quite a surprise to discover that the Iron Sheik, often credited as the heel who helped spark Hulkamania, never enjoyed the spotlight of headlining WrestleMania. Such matches were rarely workrate classics, instead relying on the charisma of both men to get over, something which Sheik unquestionably had in spades. Most Likely Opponent: Hulk Hogan. A no-brainer - and a Sheik win would probably rank above Lesnar's defeat of Undertaker for biggest 'Mania shock ever.
