In the creation and criticism of fictional works, a character flaw is a limitation, imperfection, problem, phobia, or deficiency present in a character who may be otherwise very functional. The flaw can be a problem that directly affects the character's actions and abilities, such as a violent temper. Alternatively, it can be a simple foible or personality defect, which affects the character's motives and social interactions, but little else. In general, flaws can be categorized as minor, major, or tragic.
