Forneus

Forneus (フォルネウス, Foruneusu) is a recurring demon in the series.

History
According to the writings in The Lesser Key of Solomon, Forneus is the thirtieth spirit listed in the Goetia. He is a Great Marquis of Hell with twenty-nine legions under his command, partly comprised of the order of Angels and Thrones, and appears as a sea monster. When summoned, he can make men well-versed in rhetoric, give him a good name, teach him foreign tongues, and make him trusted by friend and foe alike.

Shin Megami Tensei Nocturne
Forneus is a boss found in the Hospital which you have to fight against. He doesn't like you and won't let you by. Upon defeating him, you can leave the hospital. Forneus is suggested to be a friend of Decarabia, although there is no given explanation for their friendship. Some suggest that it is because both appear as creatures of the sea, others that it is simply because they are both Marquis of Hell, although this is still only conjecture.

Persona 3
This special non-mythological relationship is rendered again in this game, in which these two personae are able to perform a combo skill called Best Friend.

Shin Megami Tensei IMAGINE
Forneus can be fused from a Divine Angel and a Wilder Bicorn.

Trivia
