When it comes to villains in the DC Universe, no one is more notorious than The Joker. He is Batman’s constant nemesis, always challenging him, targeting the people that matter to him most, all in an attempt to get him to see what he calls the joke of morality.

Joker Ending, Explained

Joaquin Phoenix and Todd Phillips really made the character their own. However, some fans were left wondering what happened in that last scene.

While the Clown Prince of Crime is at the top of the list, Joker has plenty of competition. Many of comic books’ most fearsome foes are as twisted as him, even having their own twisted codes. Here are the worst of the worst in not just DC Comics’ Rogues Gallery, but in all comics.

Honorable Mention: V

V is the Guy Fawkes-masked pro/antagonist of writer Alan Moore’s legendary work, V for Vendetta, published under DC’s Vertigo imprint. The story sees him fight a one-man war against a fascist England, seeking revenge on those who tortured not only himself, but also an actress imprisoned for being a lesbian.

It is hard to paint V as a villain, since he fights for what is arguably a just cause. His methods, however, would make the Joker one happy clown. He even ends up trapping teenager Evey Hammond in a fabricated prison, putting her through endless torture, feeding her the story of the actress, in an attempt to make her like him.

7 The Shredder Fights Without Honor

The Shredder is the longtime nemesis of the Teenage Mutant Ninja Turtles. He rules New York City’s Foot Clan with an iron fist, and despises the Turtles’ Master, Splinter, who is the mutated Hamato Yoshi in some incarnations, and Yoshi’s former pet rat in others.

The Shredder has proved, through comics, movies, and other media, that he will stop at nothing to take revenge on the Turtles and their master. In the final story of Nickelodeon’s first Teenage Mutant Ninja Turtles series, he unleashes a mutant apocalypse upon the planet. If one needs further proof that Shredder is a psychotic match to the Joker, he even recruits the Joker in the animated movie Batman vs. Teenage Mutant Ninja Turtles.

6 Victor Zsaz Sees Himself As A Gift

Victor Zsasz is a twisted serial killer, who targets his victims seemingly at random, though he has a preference for women. After each kill, he marks the tally with a cut in his own flesh.

While Joker wants Batman to see that life is a joke, Zsasz considers life a curse. He views himself as a liberator from life, seeing it as inherently meaningless. He believes killing his victims is his “gift” to them. Zsaz is particularly sinister in the video game Batman: Arkham City. He calls payphones at random, tasking Batman to reach his targets within a given time limit. When Batman finally locates his hideout and takes him down, it is one of the game’s most satisfying moments.

5 Wilson Fisk Is The Worst Villain Of All: A Corporate Businessman

Wilson Fisk is one of the Marvel Universe’s largest foes, both metaphorically and physically speaking. He has crossed paths with not only Daredevil, but also the friendly-neighborhood Spider-Man. What makes him a villain to be feared is that he is one of the most believable in comics, commanding a vast corporate and criminal empire, and stopping at nothing to get what he wants.

The Ultimate Spider-Man comics iteration of Kingpin pulls a particularly devious act. Having discovered he owns the rights to Spider-Man’s name, he can profit from any merchandise with his likeness. Having Spider-Man abducted, he rubs his ownership of the name in Peter’s face. No matter how much good Peter does as Spider-Man, Kingpin still profits in the end.

4 Spellbinder Preys On The Youth Of Neo Gotham

Unfortunately, Gotham City will always need a Batman. That is where Batman Beyond’s teenager Terry McGinnis comes in. An elder Bruce Wayne sees the potential in the troubled teenager, and empathizes with the loss of his father. He takes on McGinnis as his apprentice, training him to tackle a new generation of villains.

One of these foes is school counselor Ira Billings, who takes on the villain mantle of Spellbinder. While other incarnations have appeared in Batman comics, Billings is arguably one of the darkest incarnations. One of his schemes involves hooking youth from difficult backgrounds on a hyperrealistic and addictive virtual reality simulation, and make them commit crimes for one more fix. Even Terry’s best friend and honorary Robin, Max, falls victim, until Terry convinces her to turn away from him.

3 The Green Goblin Took The Woman Spider-Man Loved

Spider-Man has had his collection of colorful villains, but the one who has caused him arguably the most trouble is the Green Goblin. He was born when CEO Norman Osborne of Oscorp experimented on himself, creating a Mr. Hyde to his Dr. Jekyll called the Green Goblin.

Spider-Man: Every Video Game with Green Goblin

With the arrival of Green Goblin in the Spider-Man: No Way Home trailer, it's time to look at the villain's various video game appearances.

Just as the Joker did to Batman, the Green Goblin has targeted those whom Spider-Man cares for the most. His greatest victory over Spider-Man came when he threw his unconscious girlfriend, Gwen Stacy, from the top of a bridge. Spider-Man attempts to save her, only to find that the sudden pull from his webbing snapped her neck, killing her.

2 Ra’s al Ghul Is Batman With No Limits

Ra’s al Ghul is the head of the League of Assassins, a global terrorist group that seeks to purge the world of corruption. In Christopher Nolan’s Batman film trilogy, it is known as The League of Shadows, and al Ghul is played by Liam Neeson. Thanks to the Lazarus Pit, al Ghul has rejuvenated his body many times, allowing him to live to see several centuries. While he and Batman are foes, al Ghul respects the Caped Crusader as a worthy opponent, giving him the nickname “Detective.”

At first glance, al Ghul’s and Batman’s goals may align. However, he is a twisted fun house mirror of Batman without his moral code. He believes the only way to purge the world of corruption is to terminate it with extreme prejudice. The Joker may be a maniac, but at least he knows it.

1 Harley Quinn Is Joker’s Twisted Match

The bad girl Harley Quinn first appeared in Batman: The Animated Series, and has experienced a new surge in popularity thanks to the Suicide Squad films. She is also set to appear in the video game Suicide Squad: Kill the Justice League. Harleen Quinzel was an intern psychologist at Arkham Asylum. It was there that she met the Joker, who, over numerous sessions, manipulated her into falling in love with her. She eventually breaks Joker out of prison as her villain persona.

Harley Quinn's Coolest Weapons, Ranked

Throughout her appearances in comics, movies, games, and TV, Harley Quinn's arsenal is anything but ordinary.

Harleen is, at least on paper, a perfect match for the Joker. In The New Batman Adventures episode, Mad Love, she says herself that she is attracted to “extreme personalities,” finding them more exciting and challenging. She is even a manipulator herself, having seduced a College professor to give her a passing grade in The Batman Adventures one-shot, "Mad Love." In reality, though, Joker is abusive, and Harley can’t seem to break free from his spell. More recently in the comic books, Harley has broken off from him, and is living a life of crime on her own terms.
