Lex Luthor is often an interesting character in such fanfictions. He might be the one pulling the strings behind the scenes, fueling Batman's distrust of Superman. Another could be Alfred. His wisdom and influence on Batman can add depth to the story. He might try to talk Batman out of fighting Superman or help him in a more covert way. And then there's Wonder Woman. She could be caught in the middle, trying to mediate between the two or having her own motives for getting involved in their conflict.
One popular plot could be that Batman discovers Superman has been mind - controlled by some villain. So, in order to save Superman and the world, Batman has to fight him. Another plot might involve a misunderstanding. Maybe some false information leads Batman to believe Superman is a threat to Gotham, and he takes action. There could also be a plot where Batman is pushed to his limits by some external force that makes him see Superman as an obstacle, and he uses his wits and skills to take on the Man of Steel.
Perhaps Batman has teamed up with some of Superman's other foes who have knowledge of his weaknesses. For example, Lex Luthor could provide Batman with technology or information that gives him the edge. Also, Batman might use psychological warfare on Superman, playing on his insecurities about being an alien among humans.
Once upon a time, in a schoolyard, there was a girl named Lily and a boy named Tom. Tom had been teasing Lily for days about her new haircut. One day, Lily had enough. She walked right up to Tom, pushed him hard, and then started punching him on the arm. Tom was so shocked that he didn't even fight back at first. Lily yelled at him, 'Don't you ever make fun of me again!' and then walked away with her head held high.
Not really. In most societies, men are generally perceived as physically stronger, so it goes against the common expectation. However, when it comes to self - defense or extreme emotional situations like the ones I mentioned before, they do happen.
Alfred is always a likely ally. His knowledge and experience can provide valuable support to Batman. Also, Oracle (Barbara Gordon) could be an important ally, using her hacking skills to disrupt any technology Superman might use or to gather information.
I'm not sure about its popularity. It could be popular among die - hard Glee fans who are interested in exploring different storylines and character interactions. But without specific data on views or readership, it's hard to say for sure.
One story could be in a self - defense situation. For example, a man was harassing a woman on the street, trying to grab her purse and touch her inappropriately. The woman, who had some martial arts training, fought back and beat up the man to protect herself.
In a neighborhood, a girl, Emma, noticed a guy, Ryan, being mean to an old lady. Emma was into martial arts. She stepped in between Ryan and the old lady. Ryan tried to shove Emma aside, but she blocked his move and delivered a series of punches and kicks. Ryan ended up on the ground. Emma's actions made her a hero in the neighborhood and taught Ryan not to be so unkind.
Well, it could be about a scenario where Peter (presumably from some fictional universe) gets into a physical altercation with Flash. Maybe in this fanfiction, Peter has been pushed to his limits by Flash's actions or words, so he decides to beat him up. It could be a way for the author to explore the characters' relationships and emotions in a more extreme way.
