Sidney Raymond Eudy, a professional wrestler known as Sid Vicious who was known for his intense persona and imposing stature, has died, his son announced Monday. He was 63.

Gunnar Eudy, one of the wrestler’s two sons, wrote on Facebook that his father died after “battling cancer for several years.”

“He was a man of strength, kindness, and love, and his presence will be greatly missed,” his son wrote. “We appreciate your thoughts and prayers as we grieve this loss.”

The 6-foot-9-inch Eudy went by many names in the ring, including Sid Justice and Sycho Sid, and rose to prominence at the height of the WrestleMania craze in the 1990s. He was a two-time champion in the World Wrestling Federation (now World Wrestling Entertainment) and also performed for its ’90s rival World Championship Wrestling and the United States Wrestling Association. He faced off against Hulk Hogan and The Undertaker among other stars.

In a statement, WWE called Eudy “one of the most imposing and terrifying competitors of his generation” who had a “natural charisma that immediately connected with the WWE Universe.”

“Sid’s reputation as one of the toughest and most thrilling superstars cemented his legacy in WWE, and his influence can still be seen in wrestling rings around the world,” the statement said.

Eudy was born in West Memphis, Arkansas, and lived in Tennessee for many years. Survivors include his wife, Sabrina Estes Eudy, his sons Frank and Gunnar, and his grandchildren.
