Wheel-chair ridden Edgar Jomfru ("Jomfru" meaning virgin in Danish) and his brother Eric are introduced as the proprietors of diefordethklok.com, the largest Dethklok fan site. In their greed, they attempt to blackmail Dethklok into paying for good reviews on their site by secretly recording an exclusive one-time only song, "Fansong", played by Dethklok during their annual fan day. Their scheme fails miserably when the two brothers are lured into a sniper-filled hallway by Ofdensen. Eric is killed instantly, his head blown off and the remnants of his face scattered on his brother, while Edgar, remembering Ofdensen's cryptic advice regarding how to cross the narrow corridor beforehand, survived. Edgar is promptly imprisoned inside the band's dungeon.
Edgar returns in the 2nd Season as the secondary villain of the Season (the Metal-Masked Assassin acting as the main villain). The shock of his brother's death, as well as the brutal torture inflicted upon him by the band's minions, drives Edgar insane: having recovered the remains of his brother's face from the incident, he makes them into a mask for a fellow imprisoned fan who is put into his cell, even referring to the teen as his brother upon doing so. He digs his way out of the prison in the episode "Dethvengeance," the fan tied to his back despite the latter not being handicapped. He is rescued by the Metal Masked Assassin after escaping through the sewage system. He and the assassin start the Revengencers and begin orchestrating terrorist attacks on different Dethklok-related places. The Tribunal describes Edgar as the brains behind the terrorist attacks. He has his nose bitten off by a Dethklok fan while attempting to assassinate Nathan, in the episode "The Revengencers" aka "Sicklok".
In "Black Fire Upon Us", Edgar masterminds the attack on Mordhaus and even infiltrates Mordhaus himself to personally kill Dethklok. He corners Skwisgaar and Pickles in their secret vault and prepares to shoot them with a shotgun. As he prepares to shoot them, he flashes back to all the years he and his brother spent as avid Dethklok fans. He lowers his gun as he is unable to kill what were once his idols. Immediately thereafter, a Klokateer kicks his wheelchair over and starts beating him with a night stick. His fate after this is unclear.
