4 WWE Superstars who died before the age of 30

#3 Kasavubu - 26 at the time of death

Kasavubu was a great heel back in the day.

Very few may know about Jimmy Lee Banks, better known as Kasavubu. Billed from Uganda, the 6'4" 330 lb wrestler was one of the most vicious heels in Canda during the latter half of the 1970s.

The WWE (then WWWF) got him on board in 1976 and booked him in matches against the likes of Bob Backlund, Andre the Giant and Bobo Brazil before leaving to join Stampede Wrestling. Kasavabu was one of Stampede's top bad guys and also held the North American Heavyweight Championship and Tag Team titles during his time with the company. He briefly returned to the WWE when the company had renamed itself to WWF in 1979 and went on to lose various matches before quitting yet again in 1980.

The American wrestler suffered from many health complications which drastically affected his in-ring career. He struggled with diabetes and had to take dialysis treatment during shows. His body continued to deteriorate in the following months as he developed issues with his kidney. He passed away on July 27, 1982, due to a heart attack, which occurred moments before he was supposed to undergo a kidney transplant from his brother.

Many notable wrestlers appeared on a tribute show that was organized to raise funds for the departed wrestler' family.
