Homebrew Oni Species Details

Besides great strength, many oni had regenerative abilities similar to trolls, and all oni had multiple magical abilities, including the ability to fly without wings, change their own shape, and turn themselves invisible.

Personality

Oni enjoyed both dancing and music. They particularly enjoyed the music of flutes. It was considered unwise to interrupt an oni dancing celebration!

Among animals, oni preferred black-colored ones.

Oni also were very fond of treasures of all varieties. Some oni would swallow their treasures to protect them, regurgitating them later.

 

Society

Oni often lived in desolate areas, or they might make homes along highways or within cities, living in disguise. In rare cases, they might even rule over small human villages.[3]

A band of oni might contain a hundred members, in obedience to the largest and wisest oni, whether male or female. They might be found allied with bakemono, gaki, goblin rats, or varieties of evil humanoids.

 

Ecology

Oni were carnivorous and had massive appetites. They ate both wild game and domesticated animals, and would eat humanoids as well.

Males and females were equally powerful.

 

History

The origin of oni remained a mystery to scholars. Many believed that they were the corrupted spirits of evil humans, but others thought them to have been created specifically by the Celestial Bureaucracy to test humans and establish a balance between good and evil.[3] Still others saw many similarities between the oni of the east and the ogres of the west and argued that they were in fact related races, or that oni were related to trolls.
