Corson began training as a wrestler in 1994 and adopted the ring name
John Zandig in 1999, his surname deriving from
Misfits' front man and fellow New Jersey native,
Glenn Danzig. Zandig lost to
Nick Gage in a
four-way Cage of Death match that included
Lobo and
LuFisto. Due to a prematch stipulation, Zandig was forced to retire as a result of losing. He came out of retirement for the third time at Cage of Death X, On August 8, 2009, John Zandig held a CZW Hall of Fame induction for Jon Dahmer, Hardcore Nick Gage, and Wifebeater; and recognition plaques for Mike Pancoast, Shawn and Sabine Kernaghan, WHACKS, and Maven Bentley. After announcing the Hall of Fame and special recognition plaques, Zandig announced that he was stepping down from CZW due to financial reasons and being too injured and tired to assume the duties that come with being the owner. Zandig announced that he had sold CZW, not for the price he wanted, but due to the economy it was enough to get him to sell. The new owner announced was CZW wrestler, D. J. Hyde. On October 25, 2009, Nick Gage defeated Zandig in his retirement match. On May 8, 2010, Zandig once again returned to the ring at CZW's Fist Fight and defeated Brain Damage in a Tournament of Death 9 qualifying match. Following his victory, Zandig was attacked by MASADA, setting up their first round meeting in June 2010's Tournament of Death 9 which Zandig no-showed due to injury. Zandig participated in the last CZW event held at the
ECW Arena when he fought new CZW owner
D. J. Hyde on January 14, 2012. This was the follow-up from a surprise run-in at
COD 13 when he attacked Hyde during his match with Greg Excellent. He returned to the ring once again on the 5th of June 2016 in another deathmatch tournament organised by him, this time in
Game Changer Wrestling (GCW), called Tournament of Survival. He was not originally scheduled in the tournament and was to go one on one with
Joey Janela, but when wrestler Scott Summers could not compete anymore, he took the helm and got to the finals (but dropped out) as well as defeating Janela, hitting another rooftop Mother F'n Bomb onto Janela through a burning plytube board with light tubes on top of a truck. The tournament was later won by Danny Havoc. Zandig returned to CZW on June 11, 2016 for the annual Tournament of Death. During a non-tournament match between Josh Crane and current owner, D. J. Hyde, Zandig returned to the ring alongside Ruckus and Robbie Mireno and beat down D. J. Hyde until he would give up his ownership. However, D. J. Hyde would not, so along with the help of Josh Crane, Zandig, Mireno and Ruckus buried D. J. Hyde alive until he gave up ownership of CZW. ==Other media==
