A type of fiend from Dungeons & Dragons, Yugoloths are one of the Neutral Evil counterparts to Devils (Lawful Evil) and Demons (Chaotic Evil), the other Neutral Evil type being the Demodands of Carceri. Previously known in 1st edition as Daemons, they come from the plane of Gehenna, and are known for being mercenaries in the Blood War.

There exists multiple types of Yugoloths.

Canoloths are dog-like yugoloths who are often applied as guard dogs and pets.
Dhergoloths are large arthropod yugoloths who act as brutes in combat. Interestingly, they have 5 arms total, each arranged 360 degrees around their barrel-shaped body.
Merrenoloths are the skeletal ferrymen of Gehenna.
Mezzoloths are four-armed arthropod yugoloths who serve as the general rank-and-file soldiers.
Nycaloths are large, winged yugoloths who command lesser yugoloths, and fight as elites.
Ultroloths are the high-ranking generals of the yugoloths, who scheme and plot their way into getting what they want. They have an appearance resembling large, mouthless grey aliens.
Yagnoloths maintain yugoloth provinces as minor lords. Their most distinctive physical feature is their disproportionately large left arm.
