Dagur is a man of short stature but a well-built physique. He has short, bright red hair and his body is covered in a variety of scars and tattoos, one of which is a list of names. He is physically fit, often seen exercising. His personality is eccentric and unhinged, as his title 'the Deranged' suggests, and he is prone to muttering to himself and making odd, self-referential comments.
