Bakemono

In Japanese mythology, the term bakemono (or obake) refers to "creatures that have changed from one form to another, generally becoming more powerful in the process. Usually this change is due to the presence of negative feelings, and as such, obake tend to be violent, or even malicious." In the Middle Kingdom, the tendency is greater, as the change is due to the presence of a Bane; in other words, the shen use the term to refer to fomori.
