The Undertaker

He’s undead. He’s shot lightening out of his hands. He’s thrown his enemies into coffins. He's one of the most popular pro-wrestlers of all time. But Mark Calaway’s character The Undertaker is also an anachronism from a different era of wrestling. Today WWE performers rely more on their real life personalities than invented personas, and yet The Undertaker has continued his supernatural reign in the ring for nearly three decades. Journalist Chad Dundas and professors Charles Westmoreland of Delta State and Christopher Stacey of LSU Alexandria put The Undertaker’s remarkable career in the context of “sports entertainment,” which often doesn’t get enough respect as sports or entertainment. 

Here's a link to the graphic novel Chad Dundas wrote about the origin of The Undertaker:
