Villains whose approximate Character Alignment is Chaotic Neutral, known as the "Free Spirit" alignment. These characters are wild, unpredictable, go every which way and often follow their own personal code without a care for others (though they may sometimes care about others); they are often selfish and the only thing predictable about them is their unpredictable nature. However, these characters are more willing to do harm or murder than their heroic counterparts.

It is the darker counterpart of Chaotic Neutral heroes, although both sides are considered grey most of time.

They differ from Chaotic Evil characters as they do not actively seek to destroy the natural order or cause misery around them as a Chaotic Evil would, even though they are unconcerned with questions of morality.

Chaotic Neutral often include a wide range of anti-villains:

• Vigilantes who violently punish criminals and use methods such as kidnappings or murders, regardless of the law or of the risk of unfairly punishing innocents. The Punisher is a well-known example. However, these characters are rather Lawful Neutral if they belong to a corrupted system, or uphold standards of such a system.
• Extremely dimwitted characters who cause harm to others or destroy things without realizing the gravity of their deeds. Beavis and Butt-head are an example.
• Thieves who are only for themselves, but can assist the heroes and/or be heroic as well (usually with the intent of being rewarded). Catwoman is perhaps one of the most infamous examples of this.
• On & Off assassins in an Evil Vs. Evil scenario who murder other villains and sometimes fight alongside the heroes, if they do not assume that role. Deadpool is a popular example of this.
• Protective characters or parents who are willing to do anything to protect someone they care about, even if this involves theft, burglar, murder, destruction of property, and so on (e.g. Eren Yeager).
• Predators lacking a moral agency who are seeking their prey. Siren Head is a good example.
• Mischievous characters who mostly play pranks and are not so evil or not meant to be taken too seriously, except if they commit crimes that go beyond the regular mischief such as murder or torture. An example of that is Beetlejuice.

Pure Evil villains NEVER fall under this alignment. The type of Pure Evil villain that falls under the chaotic character alignment always falls under Chaotic Evil.
