Who are the most common characters to cross over with the Joker in 'joker crossover fanfic'?

Pokémon characters are often seen in doraemon crossover fanfic. Pikachu could interact with Doraemon in many ways. Maybe Doraemon could use his Memory Bread to help Pikachu learn new moves faster. And Pikachu's electric powers could be used to power some of Doraemon's gadgets in case of a power outage.

Batman's allies are very likely. For example, Robin. The Joker would see kidnapping Robin as a great way to taunt Batman. Also, Commissioner Gordon might be a target as he represents law and order, which the Joker loves to disrupt.

I'd say Harley Quinn. She has a very unique relationship with the Joker. Her love for him, despite his insanity and abuse, adds a lot of depth to her character. And then there's Robin. His youth and idealism in the face of the Joker's evil present a great contrast. He represents the hope that Gotham can be saved from the likes of the Joker.

Ruby would likely be very confused at first. She's used to fighting Grimm and more straightforward villains. The Joker's erratic behavior and mind - games would be a new and challenging thing for her. She'd probably try to understand his motives and find a way to stop him from causing more harm. Weiss would be distrustful right away. She's from a high - society family and the Joker's unruly nature would be completely opposite to what she's used to. She might see him as a threat not just to the world, but also to the order she values.

Harley Quinn is quite interesting. She's caught in the middle between her love for the Joker and her own sense of self. Commissioner Gordon is also important. He's the one who often has to deal with the aftermath of Batman and the Joker's battles and is a symbol of the law in Gotham.

The other Phantom Thieves are very common. Characters like Ryuji, who is brash and energetic, often appears alongside the female Joker. Morgana, the cat - like guide, is also frequently in fanfictions with her. And Ann, with her model - like looks and strong will, is another common supporting character.

There could also be a heroic character, like a young inventor who is trying to oppose the chaos caused by the Clockwork Joker. This character would use their intelligence and knowledge of mechanics to outwit the Joker and save the day.

Batman is definitely one of the main characters. He is the Joker's nemesis, and their interactions drive a lot of the story.

Another popular character could be Miyoshi. He has a certain charm and naivete in the original, and in fanfiction, this can be played with in various ways. For example, his growth as a character or his relationships with other characters can be explored more deeply, which makes him a favorite in the fanfiction world of 'Joker Game'.

Definitely Ultraman. He is a well - known Japanese superhero, and when combined with Godzilla in fanfic, it creates a great mix of super - powered action. Also, Gamera is often crossed over with Godzilla. They are both giant turtle - like monsters in their own rights, and the crossovers usually involve some intense battles over who is the more powerful or dominant one.
