Grant Berkland, better known as Danny Havoc (May 19, 1986 – May 31, 2020) was an American professional wrestler.

He made appearances for Game Changer Wrestling (GCW), and is best known for his work in Combat Zone Wrestling (CZW), where he was known for mixing his technical style with hardcore, winning the Tournament of Death twice. At Tournament of Death 16, he announced his retirement and on September 9, 2017, wrestled his final match against Alex Colon at Down With The Sickness. He has also wrestled for Westside Xtreme Wrestling (wXw), Big Japan Pro Wrestling (BJW), IWA Mid-South, IWA East Coast and IWA Deep-South.

Two years later, Havoc came out of retirement for Matt Tremont's H2O Wrestling at a benefit show. In February 2020, he returned to Game Changer Wrestling (who he had made special appearances from 2015 to 2017) for their Tokyo tour.

Personal life

On April 4, 2020, Havoc's wife, Brianne, died of heart failure. Less than two months later, on May 31, Game Changer Wrestling announced that Havoc had died, just 12 days after his 34th birthday.
