He and Edgar were among the many Dethklok fans who were allowed into Mordhaus during Fan Day. They secretly recorded Dethklok's exclusive one-time only Fansong, and attempted to use it in order to blackmail Dethklok into paying for good reviews on their fan site by threatening to release the Fansong. Offdensen seemingly agreed, and led them into a corridor. Unknown to the brothers, the corridor was actually surrounded by snipers, and once Offdensen gave them the signal, started firing. The first shot blew off Eric's head except for the lower mouth and the tongue, killing him.
Eric's face, however, was preserved by Edgar, and put it onto the Teenager's face. He then began calling the Teenager his "brother", referring to Eric. Edgar has since been acting as if the Teenager is Eric.
