- "A joke a day keeps the gloom away!"
- ―The Joker[src]
The Joker is an arch-criminal obsessed with absurdity and joke based crimes. Clown-like in appearance and personality, his behavior is very often akin to buffoonery. His abilities as a master conjurer allow him to effortlessly escape from prison many times, making him even more of a threat. Luckily, his crime waves often follow some pattern or theme that usually allows Batman and Robin to predict his next move.
Nothing much is known of Joker's past except that he is well known for his skill with electronics and was a hypnotist when he was younger. He is now known by many as the Clown Prince of Crime with his fiendish cackle and cunning mind. One of his first goals was to unmask Batman, which ultimately failed. Some of his crimes were for little more than goofy amusement, while others were a little more destructive.
Some time later, Joker teamed up with Penguin, Riddler and Catwoman to form the United Underworld, to disband the United Nations. His role in the Combination Trap (devised by the Riddler) was the Jack-in-the-Box to send Batman flying toward the Penguin's exploding octopus, however one of the unnamed thugs fell onto the jack in the box and was killed by the exploding octopus. The four super criminals managed to dehydrate the nine members of the United World Security Council and take them to the submarine, however Batman and Robin draw it to the surface, where the Dynamic Duo fight the United Underworld. After taking several beatings from Batman, the Joker is finished off by Robin, who punches him over the edge, into the water. He is captured along with the other criminals when Batman and Robin chain them to the side of the submarine and Batman calls the coast guard where the police can take them to prison.
His many schemes after this included committing crimes based on the signs of Zodiac, stealing the famous Renaissance art collection for ransom and trying to take over Gotham City with a flying saucer. He can also easily persuade women to help him in his crimes with his charm and wits.
He was also one of six arch-criminals freed from prison by Dr. Cassandra Spellcraft to form her new invisible gang, but this brief cameo appearance was by a stand-in.
Even though Batman defeated him many times, the felonious funnyman never rested until the last laugh was his.
The Joker was one of the more obsessed villains with unmasking Batman or finding the location of the Batcave. Despite his frenzied efforts to expose the Caped Crusader, Joker was not one of the show's two villains who discovered Batman is actually Bruce Wayne, although he did come close a couple of times.
The most memorable time was when he ran into Bruce's study during a failed robbery at Wayne Manor and accidentally tripped the Batpole switch which opened the secret entrance to the Batcave. He mistook it for a secret passage and slid down one of the poles. However thanks to the quick thinking of Bruce's faithful butler Alfred who turned on the Emergency Batpole Elevator, Joker never reached the bottom and instead crashed to the top of the shaft. He was then further tortured by Alfred giving him several trips up and down the pole before finally being arrested.

Behind the Scenes
- Unlike the DC Comics, there is no mention of either how his physical deformity at Ace Chemical Processing Plant permanently changed his appearance or his origin as the Red Hood.
- By contrast with the DC Comics' treatment of the Joker as Batman's greatest enemy, Batman seems not to regard him as any more dangerous or cunning than The Penguin, The Riddler, or Catwoman.
- He is not shown to be as homicidal as his comic counterpart, and does not use his signature weapon, Joker Venom, that makes people laugh themselves literally to death and leaves their corpses with rictus grins on their faces. However, in , "The Joker Trumps An Ace"/"Batman Sets the Pace", he did use deadly gas, but made sure his henchmen safely drained it out of the death trap to make sure civilians wouldn’t get killed by it.
- In an interview with Joel Eisner about his role, published in The Official Batman Batbook, Cesar said, "Why Dozier wanted me I'll never know because I asked his wife, Ann Rutherford, 'Why did Bill think of me for this part?' She said, 'I don't know. He said he saw you in something, and he said, "He's the one I want to play the Joker."' I haven't the slightest idea what it was that he saw me in, because I had never done anything like it before."
- Because Cesar Romero refused to shave his mustache, the make-up artists working with Ben Nye Sr., who designed the Joker make-up format for color television, had to cover it with as much white make-up as they could. It did show up in a lot of close-ups. Also In another interview with Joel Eisner about his role, published in The Official Batman Batbook, Cesar said, "The make-up took about an hour to put on, but the wig was a thing that bothered me more than anything else. The wig was green of course, but it sometimes photographed red, yellow - everything but green. They would glue the wig to the front of my forehead, and after a while it would give me a headache."
- In the DC Comics, the Joker's entire body is bleached chalk-white, but this version of the Joker only has a white face and his hands and the rest of his body are shown to be a normal color as seen in "The Joker Is Wild", this is most likely due to the fact it would of taken even longer by the make-up artists to apply Cesar's make-up everywhere else as well as Joker having always been known to wear gloves.
