Sir Dagonet was an elite intelligence squad officer of the Forever Knights.
In Andreas' Fault, he came to take Argit out of a Forever Knights castle. He then captured Argit, Ben, Gwen and Kevin, and tried to execute Andreas, but after his MG42-like weapon was broken, he set it to self-destruct (which contained enough power to destroy 5 square miles). The exlosion was stopped by Andreas sacrificing himself. He then teleported away with the other Forever Knights.
