Owen Hart wrestled for most of his career in the World Wrestling Federation, using his real name as his ring name; shortly before his death he also played the gimmick of The Blue Blazer, a failed superhero in costume.

A member of the Hart family, he was the youngest of WWE Hall of Famer Stu Hart's 12 children. With his brother Bret, he carried on a long feud in the early nineties, culminating in a Steel Cage match at SummerSlam 1994.

Hart's success in Japan and the Stampede's partnership with the World Wrestling Federation led Owen to sign with the Stamford-based company in the fall of 1988. He made his Los Angeles debut at the Los Angeles Sports Arena in August 1988 in a mask , with the Blue Blazer gimmick. Instead of promoting Owen as Bret Hart's younger brother, the WWF decided to create a masked superhero. Blue Blazer was eliminated at Survivor Series 1988, lost on March 11 against Million Dollar Man Ted DiBiase and was defeated by Mr. Perfect at WrestleMania V.

Owen Hart died on May 23, 1999, during the Over the Edge pay-per-view at Kemper Arena in Kansas City, Missouri. His character, The Blue Blazer, was taking on the comedic qualities of a failed superhero. The idea for his entrance was to have him lowered from the ceiling by hanging from a rope; inches away from the ring, Hart allegedly jammed with the mechanism and fell awkwardly face down. However, something went wrong and the Canadian fell from a height of 24 meters, violently hitting the turnbuckle with his chest crashing into the ring.

At the end of a recorded presentation, the cameras focused only on the audience, with announcer Jim Ross earnestly explaining how Hart was really hurt. Rushed to the hospital, Hart arrived there already dead; the autopsy attributed the death to a severe internal hemorrhage, caused by the rupture of the thoracic aorta.
