Design

Appearance

Cocytus was a serpentine creature and had multiple horns shaped like a crown.

Personality

Cocytus was a violent and fearsome spirit. Upon being summoned by Crowley, it immediately attacked and acted like any wild beast.

Abilities

Cocytus was capable of handling Endymion, Rilliona, and Crowley together when they were caught off-guard. It demonstrated immunity to magical attacks, reflecting its card counterpart's immunity to card effects. It was able to unleash a fire breath attack.

When summoned to another world, it relied on magic power to sustain itself. As such, when Korozo absorbed that magical power, it disappeared.

Biography

Aleister Crowley noticed unusual behavior from magic power, which he understood to have flown into his world from another and traced its source to a dried-up spring. Crowley attempted to contain the magic power with his magical circle, but inadvertently caused it to fuse and summon Cocytus.

Crowley was delighted that the appearance of Cocytus supported his theories on magic power flowing from other worlds and the ability to summon spirits with it. However, his companions were more concerned by the unfriendly nature of Cocytus, who proceeded to attack them. Endymion and Rilliona attempted to fight back, but their magic did not affect Cocytus. Korozo then absorbed all the magic power present, causing Cocytus to disappear.
