Joker was the Batman's nemesis.
He was born by falling into a vat of chemicals, which bleached his skin, dyed his hair and drove him to insanity.
Joker went into Arkham Asylum 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 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 Ellin Yin and Ethan Bennit. He used a gun which could imprison victims in life-sized playing cards and a criminal 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 visting 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.

The Batman vs. Dracula
Likely taking place in between seasons 1 and 2, Joker first escapes from Arkham Aslyum 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 electrocauted 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 Dracula'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 Asylym."
- Joker Venom Immunity

- Gadgetry: The Joker commits crimes with countless "comedic" weapons (such as razor-sharp playing cards, acid-spewing flowers, cyanide pies, and lethally electric joy buzzers) and Joker venom.
- Genius Level Intellect: The Joker is also very skilled in the fields of chemistry, genetics, and nuclear engineering. He also seems capable of mastering whatever he puts his twisted mind to when he wants to.
- Hand-to-Hand Combat (Advanced)
- Martial Arts: The Joker also moves and fights with a Monkey Kung Fu-like style using his feet as dexterously as his hands, and often hangs from the walls and ceilings (as the series progresses, these abilities appear less).
- Singing: Joker has shown adept skills in singing when he once sang Harley Quinn a love song.
- Peak Human Condition
- This version of the character is exclusive to the continuity of the television series The Batman, related film, and the tie-in comic The Batman Strikes!. It is an adaptation of the Joker. The original character was created by Jerry Robinson, Bob Kane, and Bill Finger and first appeared in Batman #1.
- Joker was voiced by Kevin Michael Richardson.
- Joker's line expressing how men are easily driven insane and how he became what he is after only "one rotten day" is based off a monologue about the entire world in comparison to the Joker in Batman: The Killing Joke.
- The long dreadlocked hairstyle of Joker is inspired by the Jester's Hat, which are quite associated with The Joker or even The Fool.
- Basil Karlo, at the end of his first episode "Clayfaces", shows that he has somewhat of a friendship with the Joker. Ironically, the original Clayface has a gigantic grudge against the clown.
- 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 opossed 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...
