The chaotic neutral alignment, a character alignment from the role playing game Dungeons & Dragons, is marked by selfishness and reluctance to follow or recognize the existence of rules. Chaotic neutral characters are unpredictable, selfish, disloyal and independent. A strongly chaotic neutral character is chaotic to the point of seeming insane to outside observers.
A chaotic neutral character doesn't care what happens to other characters, and he almost always puts himself first. These characters don't believe there is any order to the universe and may spread chaos just for fun. Completely unreliable, such characters can wreak havoc on carefully planned campaigns, doing spontaneous actions just because they feel like it. Leaders can't depend on chaotic neutral characters to follow orders, nor can leaders rely on the allegiance of chaotic neutral characters in the middle of a battle.
Chaotic neutral characters don't believe in honor or codes. They are just as likely to fight dirty or run away from a battle as they are to stand and fight fairly. They are among the most mercenary of characters. Dungeons & Dragons players often refer to this character alignment as "chaotic greedy."
Fictional characters who fit the chaotic neutral profile include Snake Plisskin from "Escape from New York," Captain Jack Sparrow from "Pirates of the Caribbean" and Jayne Cobb from the television series "Firefly."
