The Joker The Joker is a homicidal maniac and the archenemy of Batman. Although his full origin is unknown, the Joker is known to have been forced to swim through a vat of chemicals which turned his skin white, his hair green, and left his face permanently locked in a double Glasgow Grin. Completely unpredictable with no regard for human life, the Joker finds murder and mayhem funny, and is perhaps the most dangerous man on Earth with a body count stretching into the thousands, all centered around his obsession with destroying the Dark Knight. The Joker has a substantial list of significant crimes, although his entire criminal history is too lengthy to be recounted. His most consistent theme is personal attacks against Batman, often through loved ones and members of the Batman Family, but he has shown complete indifference as to who his victims are, as it doesn't really matter to him. In the events of "Killing Joke", He arrived at Gordon's house, and before kidnapping him, shot his niece in the spine then took pictures of her naked and bleeding and in pain on the floor, to force the Commissioner to watch in a slideshow. Although the Joker did not know this when he shot her, James Gordon's niece was actually Barbara Gordon, a.k.a. the original Batgirl, she was left crippled for life. Later, in Death in the Family, the Joker actually murdered Jason Todd, the second boy to don the guise of Robin. Jason had been searching for his mother in Africa, and found out too late that she had actually been involved in criminal activity with none other than the Clown Prince of Crime himself. Jason's mother betrayed him, and the Joker tied the two of them up together in a warehouse set to blow up. He also viciously beat Jason with a crowbar many times, causing severe trauma to his head. Batman was unable to rescue the two of them before the bomb's detonation, and they were both killed in the explosion. Another example of Joker's sadistic nature, he took an entire hospital room full of newborn infants hostage. When Detective Sarah Essen, Jim Gordon's wife, arrived on the scene, he pointed a gun at her and told her not to move, then threw a baby at her. Sarah instinctively went to catch the small child, and the Joker shot her in the head. Oddly enough, he seemed to take no pleasure in this act. Later, when Gordon found out, he was on the verge of murdering the Joker but instead was calmed down and only shot him in the knee. The Joker was immediately concerned about the damage to his leg, worrying that he might never walk again, but quickly cracked up laughing, realizing there was a joke. The Commissioner had just gotten him back for the damage to his niece. The Joker's insanity appears to be a strange mixture of violently aggressive psychopathy, nihilism, and fixated narcissism. He has frequently been shown to have no regard for human life, and treats the pain and suffering of others as personal sport. In the mini-series Underworld Unleashed, The Trickster remarks, "When super-villains want to scare each other, they tell Joker stories". As far as truth about Jokers personality, one word sums him up best unpredictable. Abilities Pain Resistance- It is speculated that the Joker's exposure to chemicals may have heightened his resistance to pain. It is also implied that he is masochistic in nature, and thus enjoys any pain received, making it an ineffective way of dealing with him. Immunity To His Own Poisons & Venoms- It has been said that "being an avid consumer of his products, Joker's immunity to poisons has been built up over years of dedicated abuse." When a mosquito sucks the Joker's blood, it "writhes and whines, choking on tainted blood". The Joker is also immune to his own venom as well as various similar toxins. Indomitable Will- The Joker's insanity, or his frame of mind, leaves him immune to the Spectre's judgement, though warranted, as Batman explained once that the Joker doesn't actually know what is right and wrong, a crucial understanding the Spectre needs to judge. In a way, one has to know one's deeds are evil or wrong for the Spectre to judge, and the Joker doesn't. Also, both Jim Corrigan and Hal Jordan Spectres have had major problems with navigating the Joker's mind, Corrigan even managed to get lost in it and Jordan literally was blasted out of his boots to the moon when he tried. Genius-level Intellect- The Joker is portrayed as highly intelligent and skilled in the fields of chemistry and engineering, as well an expert with explosives. From his first appearance onward, he has been consistently portrayed as capable of hijacking broadcasts - usually news programs - of both the television and radio varieties. He also has incredible inventive skills, creating countless "comedic" weapons (such as razor-sharp playing cards, acid-spewing flowers, cyanide pies, and lethally electric joy buzzers) and Joker venom, in which he uses in his crimes. He has also been known to be proficient at escapology, & tactical analysis. Hand-to-Hand Combat (Basic)- The Joker has moderate skill in hand to hand combat. Over the years it has been shown that although Batman is stronger, the Joker is faster and more agile. The Joker has been known to be able to hold his own in hand-to-hand combat against Batman, however every time he is subdued by Batman, it is through physical force. However, the Joker has proven to be very skilled in the area of martial arts as well, this being proven when beating the Batman once in a fight without "cheating". Intimidation- Joker is adept at torturing his victims endlessly, including shooting Batgirl, torturing Robin to death and beating Damian (the third & current Robin) into submission. Assets Joker Venom- A deadly poison that infects his victims with a ghoulish rictus grin as they die while laughing uncontrollably. This venom comes in many forms, from gas to darts to liquid poison, and has been his primary calling card from his first appearance. Various Joker Gadgets- Razor-sharp playing cards, acid flower, various guns and other weaponry. The Joker is unpredictable in that he will use any kind of weapon afforded him. Joker's Joy Buzzer- The Joker often used a modified novelty joy buzzer strapped to the palm of his hand. The buzzer administered a lethal dose of electricity into anyone who came into contact with it.
