10 Oldest Wrestlers To Ever Compete At WWE SummerSlam

Over 30 years of playing a character who could not die, Mark Callaway himself seemed to become impervious to time. Over and over again, critics heralded "the end of The Undertaker" only for Callaway to shock everyone with a brilliant match. This is exactly what happened in 2015 when Taker rose from the grave to exact revenge on the man who killed his Streak.

The Undertaker and Brock Lesnar faced off in the main event of SummerSlam 2015, 16 months after the F5 heard 'round the world. Undertaker had looked in awful shape in their last match, thanks in no small part to a concussion sustained early on, but here he looked like a new man.

Taker put in a far better performance this time around, despite his age of 50 years 4 months and 30 days. He and Lesnar were on their way to a classic when a screwy finish involving an overactive timekeeper ended the match in a big, confusing blob. Still, this proved that Taker could still go, which set up his and Brock's match at Hell in a Cell later in the year; argubaly the final great performance of The Undertaker's legendary career.
