Maxie Zeus is a rather unique villain. His origin story has him as a man who became so obsessed with Greek mythology that he started to believe he was Zeus. He uses his knowledge of mythology to plan his crimes in a rather elaborate way. Calendar Man is another one. His origin is linked to his obsession with dates and time. He commits crimes based on significant dates in the calendar, often using his knowledge of history and events related to those dates to create elaborate and symbolic crimes.
The Joker's origin is quite complex and has been told in various ways. One popular version is that he was a failed comedian who had a bad day that pushed him over the edge into madness. Another villain, Two - Face, was once Harvey Dent, a respected district attorney. But after a tragic accident involving acid, which horribly disfigured half of his face, he became Two - Face, with his dual - natured personality representing the struggle between good and evil within him. And then there's Catwoman. Her origin often involves a life of crime born out of necessity, growing up in a tough environment that led her to steal to survive, but she also has a sense of justice that makes her relationship with Batman so interesting.
Two - Face, also known as Harvey Dent. He was a respected district attorney in Gotham. However, during a trial, a mob boss threw acid at him, which horribly disfigured half of his face. This physical and mental trauma caused him to develop a split personality. One side is still the law - abiding Dent, while the other is a vengeful and criminal - minded Two - Face. He makes decisions based on the flip of a coin, which represents the duality of his existence.
One of the most intriguing Bruce Wayne fanfiction stories in the Batman Begins universe is those that focus on his pre - Batman days. Stories that show his travels around the world, learning different fighting styles and philosophies. For instance, a story might detail his time in the Far East, training with martial arts masters and how that influenced his later combat techniques as Batman.
Sinestro is another interesting case. He was once a Green Lantern. However, his strict and sometimes extreme views on order led him to be exiled. He then found the yellow power of fear and formed his own Sinestro Corps. His origin shows how a once - heroic figure can turn into a villain due to differences in ideology and the thirst for power.
One of the most intriguing storylines could be where Batman is interviewed about his first encounter with the Joker. It would give a deep insight into his thoughts and how that encounter shaped his view of Gotham's villains. Another interesting plot could be an interview that delves into Batman's relationship with his allies like Robin or Alfred. How he feels about their support and how it impacts his crime - fighting. Also, a storyline where he's interviewed about his no - kill rule and the moral dilemmas he faces when dealing with the worst of Gotham's criminals would be really engaging.
The origin story of the Green Goblin is quite compelling. Norman Osborn was a wealthy and ambitious businessman. His experiments with performance - enhancing drugs to gain an edge in the military - industrial complex drove him mad. His split personality as the Green Goblin emerged, with one side being his normal self and the other a maniacal villain. Another is Catwoman. Selina Kyle grew up in poverty in Gotham. She turned to thievery to survive, and her encounters with the corrupt underbelly of the city made her a complex anti - hero/villain. She has her own code but often goes against the law.
A possible crossover could involve the corruption aspect. The Shinju in Naruto has been associated with negative forces and power - hungry individuals. In Gotham, there is also a lot of corruption. Batman is constantly fighting against it. A fanfiction could show how the Shinju's influence might seep into Gotham, corrupting some of its inhabitants, and how Batman tries to stop this new form of evil. He might even have to team up with Naruto characters who understand the Shinju better to save the city.
One possible plotline could be that Batman confesses his love for Wonder Woman during a dangerous mission. They're in a tight spot, and he realizes he might not get another chance. So he blurts it out, adding a whole new layer of tension to their already complex relationship as superheroes.
One possible plot twist could be that Pennywise actually has a fear of bats, which gives Batman an unexpected advantage. Another could be that Pennywise manages to possess Batman and uses his skills and resources to wreak havoc in Gotham, but Batman's consciousness fights back from within. Or perhaps there's a plot twist where the two form an unlikely alliance to fight a greater evil that is threatening both their existences.
The Joker is probably one of the most popular. His chaotic and unpredictable nature makes him a great character to explore in fanfiction. Writers can come up with all kinds of crazy scenarios for him. Harley Quinn is also very popular. Her relationship with the Joker and her own journey of self - discovery are often the focus of fanfictions. Another popular one is Bane. His physical strength and strategic mind are interesting to write about, especially in battles against Batman. And then there's Catwoman, who has that alluring and complex personality that draws in readers and writers alike.
