The series finale begins with the news of Roy Cornickelson being killed by Salacia. Dethklok will attend a funeral, with Nathan giving his eulogy. Before they could go there, they are taken to the Church of the Black Klok by Charles. Their leader is Ishnifus Meaddle (voiced by Werner Herzog) who counts on Dethklok to fulfill an ancient prophecy. One day, at Roy's funeral, Nathan struggles to speak the eulogy. He admitted to Pickles that Nathan's sorry for destroying the liquid master and falling in love with Abigail without heeding his warning. Pickles, with a change of heart, reconciles with Explosion. The bomb explodes, leaving everyone in a distant rampage caused by the Revengencers, lead by The Metal-Masked Assassin and Magnus Hammersmith.

As the Man with the Silver Face is about to back Charles off, Offdensen successfully backs him off with Cornickleson's torso
