DC has some of the most dangerous villains in the comics industry. While super villains are known for killing hundreds of people, some of them can be defined as serial killers because of the pleasure they take in killing and the way in which they kill.

Some villains will seek out people to kill, rather than just doing it in order to achieve an aim. Obviously, most of the characters on this list will be Gotham city villains as it's the kind of place that has created lowlives and killers. Here are 10 of the worst serial killers in DC comics.

10 VICTOR ZSASZ

Victor Zsasz has serious mental health issues that he struggles with on a daily basis. Not only this, he's also a psychopath and takes great joy in killing other people, especially young women. But there's an extra twisted part to this already dark tale.

Every time Victor kills someone he tallies the death on his body, by scarring himself with a knife. Often, this is the same knife that he has committed the heinous crime with. This madman has never changed his ways and is extremely creepy and dangerous.

9 THE JOKER

It seems obvious that the clown prince of crime is a serial killer, considering he goes out of his way to create a strange trap or gadget to maim and disfigure random members of the public. The Joker is one of the most sadistic murderers that Batman has ever faced.

It's difficult to keep track of how many people the Joker has actually killed over the years. Rarely are these deaths even necessary to a larger plan and are simply because the Joker wants to have a bit of fun. The methods of these murders are always ghastly.

8 PROFESSOR PYG

Another Gotham City villain now and the character could be the creepiest on this list. The 'Professor' wears a pig mask to scare his victims and is more like a butcher than any kind of professor we've seen. His murders replicate that.

The killings he commits usually involve crude weaponry, chainsaws, and various experimentation. He's even tried stitching humans back together and forcing his own pig masks onto the victims. Pyg should never be let out of Arkham Asylum, he's just too dangerous.

7 SINESTRO

You wouldn't necessarily think of Sinestro as a serial killer. He has, of course, killed hundreds of people but the assumption is that this is all part of a larger war with the Green Lantern corps. But we believe that he actually takes great pleasure from the deaths.

Sinestro has created a situation in which he can kill as many people as possible. He feeds off of that fear which gives him even more incentive to kill after all the Yellow Lanterns don't run on willpower. This is what happens when you give a serial killer so much power.

6 HUGO STRANGE

Huge Strange from DC comics.

Hugo Strange is somehow often in charge of a large range of patients. He usually takes advantage of his position of power by experimenting on his victims and trying to learn new things about the human body. Genetic engineering seems to be his main research area.

The sadistic mind of Strange, however, isn't just interested in his scientific studies. He loves the power he has over the victims in his control and he enjoys taking life, even if he tries to treat it all as a matter of research rather than as the behavior of a serial killer.

5 BRUCE WAYNE

Bruce Wayne may be a controversial pick for this list as the traditional version of Batman obviously isn't even a villain. However, there are plenty of multiverse versions of Bruce Wayne and indeed his father Damian, who have become serial killers.

Whether it's the Batman who laughs, the Grim Knight or the many other variations on this character, Bruce Wayne has often found that killing is the best way to rid the streets of the scum he deems not worthy to live in Gotham. This isn't the justice we know.

4 LEX LUTHOR

Lex Luthor is very similar to Sinestro. If you give a callous man so much power he'll abuse it to his advantage. Lex Luthor, if he lost all his money and influence, would probably still be a cold-hearted killer, because he enjoys the power it gives him.

Luthor makes the decision between life and death all the time and often doesn't even commit the crime himself most of the time. We know he kills in order to spread fear and remove problems in his plans but he also does it just because he wants to.

3 RIDDLER

The Riddler is the kind of Batman villain that's defined by the murders he commits. Everything about the Riddler is about inflicting damage to Gotham citizens and playing games with them. He loves toying with his prey before he ends their lives.

Whether he's making them solve cruel riddles or puzzles, or perhaps he's got his victims in the middle of some twisted game show, the role of the Riddler is to continue to invent new ways to kill. Of course his dream will always be to kill Batman in a similar way.

2 DEATHSTROKE

Deathstroke is one of the best killers in the world. He's made a career around being a hitman and carrying out the job that's required of him. But, he's always enjoyed the art of the kill and is constantly developing ways in which to kill his targets much quicker.

There have been numerous versions of this character and some of them could not necessarily be considered to be serial killers in the traditional sense. However, the most common iteration of the character could absolutely be defined as just that.

1 TALIA AL GHUL

Talia is an assassin first and foremost which obviously makes her a serial killer immediately. Her understanding of death is very different from the average person because of her knowledge of the Lazarus Pits. Therefore, life just doesn't mean as much to her.

It's why she is so swift to remove a life if she deems it necessary. However, Talia will also kill even if it's not needed by the League, as she has such a callous understanding of the meaning of life. She has the psychology of a serial killer at her core.
