Morte

Morte is one of the characters of Arthurism and one of the main antagonists of the show.

Personality
Morte is one of the nightmares created by Arthur and appears to be a fusion of a human, bat and a bird (imagine him as a plague doctor). He communicates only through various birds' noises. He is skillful at tracing. He is vengeful for having his home destroyed and is hellbent to kill the ones who have wronged him, especially his creator for making him a freak.
