King Amdusias has twenty-nine legions of demons and spirits under his command and has the rank of "Great King". He is depicted as a human with claws instead of hands and feet, the head of a unicorn, and a trumpet to symbolize his powerful voice.
Amdusias is associated with thunder and it has been said that his voice is heard during storms. In other sources, he is accompanied by the sound of trumpets when he comes and will give concerts if commanded, but while all his types of musical instruments can be heard, they cannot be seen. He is regarded as being the demon in charge of the cacophonous music that is played in Hell and can make trees bend at will.
He is described as "a horse-like monster known as the Artist of Hell". He attacks by conjuring tornadoes of ripped out pages from a book. He drops the rarest combining material in the game, the Angel Halo.
A horse-headed demon that rushes at the hero and discharges powerful lightning bolts from his fingertips. He appears in the Nest of Evil. He seems hard to kill at first, but there is an easy way to deal with him: just jump over him while he dashes and lure him into casting his lightning bolt attack. Quickly get behind him and cast 1,000 Blades. He drops the Record 4, in addition to a spell called Thor's Bellow. On occasion, his lightning attack can cause Curse status.
He is a palette swap of the Discus Lord from Symphony of the Night.
