The Joker is one of the most iconic villains of the comic world, and he has been featured in several exceptionally edgy and provocative works.
He is unusually crazy and inventive, and his antics have been described as funny or murderous.
People who feel similar to the basic nature of the Joker tend to seek out tattoos depicting this drawn face. His character is mischievous and playful, but also serious and sinister. The image of the Joker reminds many of what happens when evil is allowed to flourish within a madman, but his personality is so warped that many people find solace in his madness.
The Joker represents a rebellious nature that no one can control.
He is a symbol of chaos and anarchy, and those who are attracted to these ideas associate with the Joker on a personal level, so they feel the need to express this association in a Joker tattoo.
