Marvelous Marvin Hagler, a boxer who ruled as middleweight champion from 1980 to 1987 dies on Saturday at the age of 66.

His wife, Kay G. Hagler, announced via her Facebook page that the legendary boxer dies unexpectedly at his home in New Hampshire.

Hagler was inducted into the International Boxing Hall of Fame in 1993.

“I always wanted to be somebody,” Hagler had told 'Sports Illustrated' in 1982. “Baseball, I played like I was Mickey Mantle or Willie Mays; basketball, I’d be Walt Frazier or Kareem; boxing, I’d pretend I was Floyd Patterson or Emile Griffith.”

Marvin Nathaniel Hagler, born on Mat 23,1954, had his name changed legally into Marvelous Marvin Helger.

Hagler became the undisputed middleweight champion in 1980. He famously defended his title against Tommy Hearns in 1985 in a brutal three-round fight billed as "The War."

After 12 successful title defenses, the boxing icon's career and reign as champion ended in 1987 in a controversial 12-round split-decision loss to "Sugar" Ray Leonard. 

Helger retired the following year and moved to Italy to become a successful actor in action movies.
