In 1997, Edge signed a developmental contract with the World Wrestling Federation through which he made his debut that summer. Shortly thereafter, he joined Gangrel and Christian in The Brood (even though they started as rivals). Edge and Christian started working as a tag team, and after winning the WWF Tag Team Championship, they became popular as the E&C Dynasty through 2001 at which point they started feuding with each other.
From 2001 through 2003, Edge became a solid mid-carder in singles competition through feuds with Christian, William Regal, Test, Kurt Angle, Booker T, Eddie Guerrero, and others before he suffered a neck injury which sidelined his career until April 2004. Edge returned with an obsession of becoming a headliner. On the week of WrestleMania 21, it was learned that Edge and Lita had been having a romantic relationship despite the fact that Lita was dating Matt Hardy. Matt Hardy was released from WWE due to his public airing of the personal situation, but Hardy returned to WWE about 90 days later to start an extremely personal feud with Edge, which culminated in Edge beating Matt Hardy in a Loser Leaves RAW ladder match. This personal feud led Edge to dubbing himself "The Rated R Superstar."
Edge started a feud with Ric Flair in late-2005, but at New Year's Revolution, he cashed in his Money in the Bank briefcase to upset John Cena for the WWE Championship. Edge's first reign only lasted a couple weeks before Cena regained the title at the Royal Rumble, but Edge's star was on the rise and he beat Rob Van Dam for the WWE title in July 2006. Edge reigned through SummerSlam before losing the title to John Cena.
After his first two reigns as WWE champion, Edge formed a short-lived partnership with Randy Orton until Edge beat Mr. Kennedy for the Money in the Bank briefcase and cashed in on Undertaker during Friday Night Smackdown! to become World Heavyweight champion for the first time. Their feud was delayed due to injury of both men, but it resumed in time for WrestleMania XXIV and culminated at SummerSlam in a Hell in a Cell match.At the 2008 Survivor Series, Edge returned to win the WWE chamionship when he entered a triple threat match unscheduled. After losing the title at No Way Out, he entered an Elimination Chamber match unscheduled to win the World Heavyweight championship. Later in 2009, he and Chris Jericho won the WWE Unified Tag Team titles in a triple threat match for which they were not scheduled to participate. Additionally, Edge won the 2010 Royal Rumble match as a surprise entrant. His ability to win any match in which he was not scheduled to appear led to his "Ultimate Opportunist" moniker, as well as leading Brandon A. Mayo to scientifically calculate a flawless WWE Match Outcome flowchart.
By virtue of his Royal Rumble victory, Edge faced Chris Jericho at WrestleMania XXVI. Although he failed in that match, he eventually regained the World title in December 2010 in a Fatal Four-way ladder match. Edge beat Alberto Del Rio at WrestleMania XXVII to successfully defend the championship. A few days later though, Edge was forced to retire due to the culmination of injuries to his neck and spine, surrendering the World championship upon his retirement.
Edge self-penned an autobiography titled Adam Copeland On Edge, which was released in October 2005. WWE released a DVD set in December 2008 entitled "Edge: A Decade of Decadence."
