|— Edgar Jomfru, attempting to intimidate Dethklok (scr)|
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 his former idols. Immediately thereafter, a Klokateer kicks his wheelchair over and starts beating him with a night stick. His fate after this was unclear until the episode Doublebookedklok, he is briefly shown at the end of the episode, living in a room deep underground Mordhaus. He currently appears to be working for Ofdensen (although it is unknown if he asked or is forced to work for him). It also appears he is monitoring Salacia's secret FalconBack Project.
In Diversityklok, it is confirmed that he is working for Offdensen and is researching the FalconBack Project, before mentioning he has discovered a hidden message in the Dethwater album which he believes to be a originated from whales and is currently working on translating it. The Tribunal also suspects or is aware that Edgar is alive and in Ofdensen's custody.
In Prankklok, Edgar finishes translating Dethwater and discovers that the repeated message says "Dethklok must go back into the water", which may explain the loss of the ships carrying Dethklok's new album.
In The Doomstar Requiem Edgar assists in training Dethklok and scolds them for refusing to consider Toki their brother. It is revealed that he was paralyzed in a car crash when he and Eric were driving home from a Dethklok concert, and Eric pulled him out shortly before the car exploded.
- Despite his obivious handicap, Edgar is a talented swimmer (he is even shown practicing his swimming in a pool at The Revengencers' base in a DVD extra).
- It is unknown if Edgar is working for Offdensen out of fear or to make up for his past actions against Dethklok (having possibly rediscovered his love of Dethklok and their music). It's more likely the latter is the reason why, as Edgar hasn't plotted to betray Dethklok since then.
