Character Flaw

A character flaw is part of a character's description that isn't a good thing. All humans on Earth have flaws, so characters should too.

Personality Flaws
Constant brooding over a dark and scary past is not a flaw. It is called whining.
 * Naive and easy to manipulate
 * Arrogant and self-absorbed
 * Short temper
 * Can't let things go
 * Gullible and suggestible
 * Impulsive

Physical Flaws

 * Clumsy
 * Stupid
 * Weak
 * Slow
 * Unskilled

Things such as diseases, a weak immune system, and allergies do not really count as flaws. They are weaknesses, since they are not the character's fault.
