Perhaps in an alternate universe where the lines between good and evil are blurred. The Cheetah and Batman are forced to work together against a greater threat. During their time together, they start to understand each other on a deeper level. Their mutual respect and a strange chemistry develop, which culminates in a kiss.
One possible plot could be that the Cheetah, who is usually a villain, has a change of heart. Maybe she gets injured during a fight with Batman and he shows her mercy. This act of kindness makes her see Batman in a new light, leading to a moment of unexpected attraction and the kiss.
It could be that the Cheetah has been brainwashed by some other powerful villain to target Batman. But as she gets closer to him, she starts to break free from the mind control. Batman realizes this and tries to help her fully regain her senses. In the process, they share a moment of intense connection and the kiss.
Some fans might be really excited about it. They love to see new and unexpected relationships explored in fanfiction. It gives a fresh take on the characters and their dynamics.
In a fanfiction plot, the kiss could be a result of Poison Ivy's attempt to break Batman's will. She's always seen him as a symbol of the establishment that she opposes. By kissing him, she hopes to make him more pliable. However, instead of breaking him, the kiss actually awakens a different side of Batman. He starts to understand Poison Ivy's cause more deeply, not in a way that he agrees with her completely, but in a way that makes him more empathetic. This new understanding could lead to a more complex relationship between them, with both of them constantly trying to outwit each other while also being drawn to each other on an emotional level.
One possibility could be that they are in the middle of a battle against a common enemy. As they fight side by side, there's a moment of intense connection. Maybe Wonder Woman saves Batman from a near - death situation, and in the heat of the moment, their eyes meet and they share their first kiss. It could be a spontaneous expression of their long - hidden feelings for each other that they've been suppressing due to their respective duties and the complex nature of their relationship in the superhero world.
One plot idea could be that Cheetah is forced to team up with Batman to take down a common enemy. Maybe a new villain has emerged in Gotham who has a connection to the source of Cheetah's powers. Another idea is a story where Batman tries to cure Cheetah of her condition, leading to a complex relationship of trust and mistrust between them. Or perhaps Cheetah kidnaps someone important to Batman to lure him into a trap, but then things don't go as she planned.
Well, perhaps in this fanfiction, Naruto is somehow transported to the Batman universe and is neglected by the local heroes at first. He then has to prove himself by using his ninja skills in Gotham's dark alleys, like using his shadow clones to confuse the bad guys and his speed to catch the elusive criminals.
It could be that there is some sort of misinformation spread by an evil organization. They create false evidence that Batman is planning to destroy Naruto's village. Naruto, being the protector of his village, decides to take pre - emptive action. He tracks Batman down and in a fierce battle, kills him. But then as he starts to investigate further, he discovers the truth and has to live with the guilt of killing an innocent (in this case, Batman who was misrepresented).
Maybe in a post - Cell Games world, Android 18 has become more integrated into the Z - Fighters' group. Goku, always open - minded, starts to notice her more as a person rather than an android. They go on a mission together where they are trapped in a dangerous situation. In the heat of the moment, they share a kiss as a sign of their new - found connection and a hope for survival.
One possible plot could be that Zuko and Toph are on a dangerous mission together. As they face various challenges, they start to rely on each other more and more. In a moment of intense relief after a near - death experience, they share a kiss.
One possible plot could be that Ethan and Sarah are long - time friends who have secretly been in love with each other. They are at a school dance, and as a slow song plays, Ethan finally gets the courage to tell Sarah how he feels. She is overjoyed and they share a sweet, tender kiss as the other students look on in envy.
One possible plot could be that they are on a mission together. During the mission, they face many challenges and have to rely on each other. As they grow closer through these shared experiences, a moment of intense emotion leads to a kiss.
