Background: Hardy was born in Cameron, North Carolina, the son of Gilbert and Ruby Moore Hardy. He is the older brother of Jeff Hardy. Their mother died of brain cancer in 1986. Hardy played baseball as a child and throughout high school, but had stopped by his senior year.
Context: Shortly after the departure of Matt and Jeff from TNA was made public, Matt's wife, Reby, went on a social media tirade in which she repeatedly slammed TNA, the company's new management and the way in which contract negotiations between the company and the Hardy family were conducted. A few weeks following this, the bad blood between the two sides intensified, so much so that the new management of TNA (now renamed Impact Wrestling) Anthem Sports & Entertainment issued a cease and desist letter to The Hardys' new promotion Ring of Honor (ROH), in which Anthem essentially ordered ROH as well as any broadcasting company airing ROH's 15th Anniversary pay-per-view show (on which The Hardys were to participate in a match) to not in any way speak of, indicate or acknowledge the existence of the Broken Matt and Brother Nero characters and instead to refer to The Hardys as simply Matt Hardy and Jeff Hardy. The issue with this is that while The Hardys were in TNA, they had full creative control over the Broken gimmick, with them even filming their own segments to air on TNA programming in some circumstances, thus making the Hardy family (in their belief) the owners of the Broken gimmick. It is believed that civil litigation will follow and a potential court hearing will take place regarding the final outcome on who owns the Broken gimmick: Anthem or the Hardy family. Until then, the status of the Broken gimmick remains undecided. Despite this, Matt continues to use the Broken gimmick through his social media accounts, but neither him or Jeff use the Broken gimmick at any professional wrestling shows for ROH or on the independent circuit, presumably until the results of the expected legal proceedings have been finalized.  Newly-appointed Impact Wrestling President Ed Nordholm credits the invention of and the vision behind the Broken gimmick to Jeremy Borash, Dave Lagana and Billy Corgan, and while Borash specifically had the most input into the gimmick of the three aside from Matt, the Hardy family deny that Borash was the sole person behind the gimmick. In November 2017, Impact Wrestling changed their policy, allowing all talent to retain complete ownership over their intellectual property, essentially forfeiting ownership of the "Broken" character to Hardy.  On January 31, 2018, the legal battle officially concluded when Matt legally acquired ownership of all trademarks related to the Broken universe and the Broken gimmick, which includes 'Broken Matt', 'Brother Nero', 'Broken Brilliance' and 'Vanguard1'. Matt is now able to use the Broken gimmick as he sees fit, regardless of the promotion he competes in with the one caveat being that the promotion green-lights the use of the gimmick in that promotion, which includes major domestic U.S. promotions such as WWE or ROH.
