(Y/N) is an oni, variously translated as demons, devils, ogres or trolls but are usually more than anything closer to ogres and trolls. Depictions of the oni vary widely but usually portray them as hideous, gigantic ogre-like creatures with sharp claws, wild hair, and horns growing from their heads. They are humanoid for the most part, but occasionally, they are shown with unnatural features such as odd numbers of eyes or extra fingers and toes. Their skin may be any number of colors, but red and blue are particularly common and are often depicted wearing tiger-skin loincloths and carrying iron clubs.

Oni were originally invisible spirits or gods which caused disasters, disease, and other unpleasant things. These nebulous beings could also take on a variety of forms to deceive and often devour humans. In folktales they are usually malicious, man-eating creatures to be feared and slain by valiant heroes, the oni can also have a protective function. They are often described as rowdy, party-loving bunch with fondness for contests and games.

Most of the oni, especially in folktales, are rather foolish and/or simple beings, but some are both highly intelligent and creative.

Limitations
Oni tend toward rowdy, rough and generally belligerent personalities/behavior.

Disease Manipulation - (Y/N) can create, shape, and manipulate diseases, a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not due to any immediate external injury. This includes their severity, contagiousness, methods of spreading, etc. He can control the organisms that spread diseases, including germs, bacteria, virus, or other pathogens on a cellular level, including bacteriophages, microorganisms (microscopic organisms), retroviruses, cells that abnormally grow to make cancerous tumors and cysts, and pathogens that produce genetic mutations.

(Y/N) can typically induce fatal diseases into their targets, rendering unable to fight and causing them to succumb to their illness and die. Since diseases are invisible to the naked eye, this ability can be extremely effective in combat and particularly hard to prevent.

Limitations
Healing and Curing can remove diseases

Death Inducement - (Y/N) can kill anyone and possibly even anything using varying means, either instantly, slowly over time, after certain conditions are met, or after a certain period of time has passed. May be induced by touch, at a distance, simply willing it to happen, or by performing a certain ritual.

Limitations
Users of Amortality are immune since they are neither alive or dead, and hence cannot die.
Users of varied Immortality are immune to death.
Users of Resurrection can undo death.

Elemental Immunity - (Y/N) is immune to all elements and elemental forces, being completely invulnerable to direct and indirect effects.

Limitations
May not protect against supernatural elements (Demonic, Divine, etc).

Elemental Manipulation - (Y/N) can create, shape and manipulate elements. Elements are the rudimentary, simplest or an essential part of which any material thing consists of. Elements are irreducible in nature and compose other (usually physical) things. Various combinations of elements can be used to create other things. For example, Ice could be thought of as a combination of Water and Air to produce a solid. The exact details of how elements combine, what each element does, and even which things are elements is canon/paradigm specific.
