- "All it takes is one, rotten day, to transform a normal man, into a monster... Well, in my case, a rotten day and a chemical bath."
- ―The Joker on his origins[src]
The Joker was the Batman's nemesis, believing himself to be inextricably linked to the Batman, and considered him to be his favorite sparring partner and opponent. Joker had wild green hair, red eyes, dark red lips, yellow teeth, and a milky blue tongue. He was born by falling into a vat of chemicals, which bleached his skin, dyed his hair and drove him to insanity.
Joker said that Batman's and his relationship was "like comedy and tragedy - two sides, same coin". Joker's weapons included his signature Joker Venom (called "Joker Gas" in the series), razor sharp playing cards, grenades with Joker smiles on them, and a bomb shaped like a Jack-in-the-Box. One of his most famous crimes was creating the supervillain, Clayface. Joker captured and tortured Detective Ethan Bennett, and, in order to drive him mad, he exposed Bennet to "Joker putty" a deadly chemical that he created which mutated Bennet and transformed him into the shapeshifting monster, Clayface. As Clayface, Bennet attempted to get revenge on Joker many times.
It was possible that this incarnation of the Joker had an origin similar to the Killing Joke, as he mentioned that he had always wanted to make people laugh. In a flashback to his origins, Joker was shown wearing red clothes after he emerged from the chemicals which suggested at the very least a Red Hood origin. It was also hinted that Joker would one day cripple Batgirl like in "the Killing Joke" as Barbra Gordon was shown to be confined to a wheelchair in the future.
He also maintained a rivalry with Penguin for the title of Gotham's greatest criminal.

- ―The Joker driving Ethan Bennett insane[src]
At the Beginning of his crime career Joker went into Arkham and released all inmates from there. Batman encountered him at the asylum during his investigation. Joker fought well but escaped with the intentions of spreading deadly laughing gas around Gotham City.
Batman confronted him at his headquarters, planning to take him down and stop the deadly gas. Batman fought him while they were aboard his gas-filled Blimp which was heading towards a sharp point on a statue. Batman defeated Joker and sent him into the ocean with his Blimp, leaving the defeated Joker to be captured by the police.
After that incident, Joker planned to get revenge on those who did him wrong including Batman and Police Detectives Ellen Yin and Ethan Bennett. He used a gun which could imprison victims in life-sized playing cards and a criminal named Nolan who disguised as Joker to get those victims while the Clown Prince of Crime escapes from Arkham Asylum while confusing Batman.
Batman eventually discovered his plan while visiting him in Arkham: to imprison those who he wants revenge on in life-sized playing cards to make a full deck and then drown them in the Gotham River. Batman saves one of his prisoners and then battles Joker on the roof. While Joker attempted to imprison Batman with his gun, Batman turned the tables by using it on the crazed criminal, then he was sent back to the asylum.
Joker later has obtained a special weapon which allows him to melt anything and anyone in addition to gaining two new henchmen named Punch and Judy. He melts a Vault at the Bank, robbing the money, and then goes to a large statue to change it's face as a joke but Batman and Detectives Ethan Bennett and Ellen Yin come to stop him. Joker and his goons escape but soon kidnaps Bennett with the intentions of driving him insane. While making him laugh crazily, Joker then tries to use his weapon on Ethan but Batman uses his Batarang to destroy it, but gas came out, infecting Ethan. Joker then has a fight with Batman and is knocked out with a punch to the face. Ethan later becomes Clayface thanks to jokers putty

Joker also uses his Joker Venom on Batman, planning to finally kill him in 24 Hours so he can permanently take his place. Joker uses Batman's gadgets as well as his Utility Belt and Batsuit, and uses his laughing gas against criminals and people who've committed minor crimes such as littering, jaywalking and speeding. He also uses the toxins on The mayors wife and threatens Gotham will pay if he doesn't get paid for his services. Batman desperately chases Joker so he can find the cure to survive. The crazed clown later confronts Penguin who he plans to stop since Penguin is a criminal. Batman also joins in, fighting the two off with Batman and Joker more or less working together, and Penguin is accidentally injected with the venom but is left hanging by a lamppost by Batman. Batman soon defeats Joker and manages to cure himself as well as telling the villain a joke, which makes Joker want to give up being Batman and instead continue as Joker spreading chaos.
The evil clown escapes Arkham once again after being attacked by Clayface and finds Detective Ethan Bennett which he planned to drop from a building to kill. Bennett than revealed to be Clayface and the two fought, but Batman interrupted to tell Bennett to stop which allowed Joker to escape. Joker then began robberies again at Wayne Industries but Clayface soon found him and wanted to get his revenge on him once again. Joker than convinces Ethan to become a criminal which he does by stealing Jokers art that he stole. Batman stops him and Clayface is apprehended while Joker escapes.

Batman apprehends the clown taking him to Arkham and then both Batman and Hugo Strange go into his insane mind with a device made by Strange to try and find out where she is. They found out that Joker had his own Gotham City within his own mind filled with Joker's. From there, he planned on driving the two completely insane and breaking their minds. Batman encountered Jack Napier who worked in Joker's Idea Factory but he was disposed of when he secretly told Batman some clues to find Yin. Joker cut through the floor with a saw and made him fall into a vat of chemicals, Joker then came up and said "water's warm Batman, dive in." He then went to the opera where Joker and a large crowd of Joker's attacked him. Batman soon become laughing uncontrollably into insanity. Alfred Pennyworth helped him and Batman eventually managed to get Joker into his mind thanks to learning it was a two way transmitter. Batman then managed to find Ellen Yin and saved her before the Jack N' The Box could explode.

The Clown Prince of Crime easily defeated Batgirl at the Circus and then robbed the gold ball which is Gotham's new Landmark. GCPD Officers blockade the streets and attempt to get the gold ball back from him but Joker simply threw the ball at them. Joker then fought Batman, who tried to destroy the venom several times but failed as Joker was too powerful. Alfred Pennyworth sent in the Bat-Bot as backup to help defeat "Brawn". Batgirl used the Bat-Bot to fight Joker but was nearly destroyed and Joker took Batman to another location where he'll die. Batgirl used the Bat-Bot once again against the crazed clown. Joker's venom was destroyed and he turned back to normal. Joker still claimed to be bigger than Batgirl, Batman then said he isn't bigger than him and knocked him out with a punch to the face.

The Batman vs. Dracula
Likely taking place in between seasons 2 and 3, Joker first escapes from Arkham Asylum in search of treasure. Joker tricks Penguin into thinking they will work together to find the treasure, he shocks Penguin with his joy-buzzer and runs off. After a fight with Batman, Joker falls into a river and seemingly gets electrocuted to death, much to Batman's shock and sadness.
Joker survived and encountered Penguin outside a mausoleum after being found in a fisher mans net and chased him down, only to be dragged into Draclua's sarcophagus and was turned into a Vampire. Joker's hair turned white, his eyes turned blue-white, and even his clothes were affected as well. Unlike all the other vampires, however, Joker retained his individuality and his speech as well as gained vampiric superhuman strength and speed. Nevertheless, Joker was still incapable of betraying Dracula's resting place. At one point, Joker humorously commented that the blood that he feasted on in a blood bank had a delicious flavor of "a bold finish of wild cherries with a hint of oak" before belching. joker and Batman had a battle which resulted in Joker's defeat.
Joker was taken back to the Batcave and Alfred expressed pity on him stating, "Joker has suffered a fate crueler than death." Joker suffered as a vampire due to a lack of blood but Batman gave him some of his blood to help him. Despite this Joker remained a vampire and stayed that way until Batman had managed to find a cure and reverted him back to normal. As a side effect, Joker didn't remember anything after his meeting with Penguin outside of Dracula's Mausoleum and is sent back to Arkham Asylum.
Joker often switched from a prankster-like clown to a much darker homicidal bare-foot wild man. (as in later episodes). Despite this he was always kind to his sidekick Harley Quinn and never physically abused her.
While it could be argued that this version of the Clown Prince of Crime more resembled the colorful, comic relief character featured in the comics of the 1950s and '60s and the 1960s show, he was still a highly dangerous, intelligent, and cruel character - while most of his crimes were silly and prank-like in nature, they could still be legitimately destructive. Joker treated each of his crimes like an elaborate joke designed to make his victims literally die laughing. Due to his unpredictable nature, bizarre appearance and unnerving instinct for the absurd, Joker earned a reputation as one of the most dangerous criminals in Gotham.
Sometimes he would simply intend to cause relatively harmless mischief such as messing up statues with Joker putty, pranking people with Donnie or throwing coins into a water fountain with Harley. Sometimes he will get more dangerous to the point where in "Joker Express" he fills dynamite in Gotham and attempts to blow them up to make Gotham fall into a sinkhole and when he steals Banes Venom to wreak Gotham
- "Even if we couldn't, Batsy?"
- "You're good."
- "How many Jokers does it take to screw in a lightbulb? Wouldn't know! They're too busy loosening Batman's screws!"
- "They all said I was sick in the head. They said I needed help. Well, maybe I am a bit batty. Blame it on the bats in my belfry."

- In that series, unlike all other media, the character was almost universally referred to simply as "Joker" rather than "the Joker"; this was to contrast with the way his enemy's name was similarly altered, universally being referred to as "the Batman" instead of just "Batman".
- Joker's line of expressing how men were easily driven insane and how he became what he was after only 'one rotten day' was based off the famous "one bad day" monologue from Batman: The Killing Joke.
- Joker's long, dreadlocked hairstyle was inspired by the Jester's Hat, which is often associated with The Joker or The Fool. This led fans to believe Joker was African-American, and confused them when Joker was shown to be Caucasian in a flash-back.
- Joker never used the monkey-like combat style in the comic strips, TV Series, and Live-Action movies until The Batman.
- Joker underwent relatively drastic visual changes throughout the series, bringing him closer to more conventional Joker designs. His straightjacket was switched out for the iconic purple tuxedo, his hair became shorter and less fluid, his teeth, while still jagged, were no longer "jigsaw" teeth that slotted together and he adopted a straighter posture. This accompanied the downplaying of his combat skills and ultimately resulted him being quite similar to his TAS counterpart by the end of the series.
- Interestingly enough, when Joker was changed into a Vampire by Dracula, he was the only one who appeared to have kept his identity, and even went so far as to rob a blood bank unlike his fellow victims, who seemed to have changed into mindless animals. The explanation for that could be due to his extreme insanity being able to protect him from Dracula's control (though it still prevented him from being able to tell the Batman where Dracula's location was).
- Despite Dracula himself turning Joker into a Vampire, the Count appeared to have little concern for him when he didn't return to the Crypt. It's possible that he was considered too dangerous and unpredictable by Dracula and was thus ousted from the pack (or he left of his own free will).
- This version of Joker is much nicer to Harley than his DCAU counterpart buying her a diamond the size of a softball for her Valentine's Day and choosing to indulge on her simply because he could as opposed to manipulating her to get out of Arkham. He also never physically hits or abuses her but he does leave her behind in a fire albeit out of indifference rather than active malice and it's possible he knew Batman would save her life.
