Villains are also important. The Joker from the Batman side and Shredder from the TMNT side can be great focuses. Imagine a scenario where the Joker teams up with Shredder. Their chaotic and evil natures combined could pose a huge threat to both Batman and the Turtles, and exploring how they interact and plan their evil deeds can be really engaging in a fanfiction.
One great 'tmnt and batman fanfiction' is 'The Dark Turtles'. It combines the grittiness of Batman's Gotham with the fun and unique personalities of the Teenage Mutant Ninja Turtles. The story has an interesting plot where the Turtles end up in Gotham and have to team up with Batman to fight a common enemy.
Obviously, Batman is one of the main characters. He's the Dark Knight from Gotham City. And then there are the Teenage Mutant Ninja Turtles - Leonardo, Donatello, Michelangelo, and Raphael. These are the core characters that are likely to drive the story forward in this graphic novel.
The main family members can be great to focus on. Their relationships, power struggles, and dreams offer a lot of material. For example, the patriarch of the family who has to make tough decisions to keep the ranch going. Another good character could be the strong - willed matriarch who holds the family together. Also, the young and rebellious heir who wants to do things his own way.
Sersi is a great character to focus on. She has a strong connection to humanity and her powers are quite interesting. You could explore her relationships with humans in more detail. Another good one is Ikaris. His loyalty and the internal conflict he might face are good material for a fanfiction. Then there's Kingo, with his love for movies and his unique charm among the Eternals.
All of the members of 4 town are great to focus on in different ways. Tae Young, for example, might be the subject of a fanfiction where his amazing dancing skills are the center of the story. Maybe he gets an offer to be in a big dance competition outside of the band, and he has to decide whether to take it or stay loyal to 4 town. Each member brings their own unique traits that can be explored in fanfiction.
The Joker, despite not being a central character in 'Batman Assault on Arkham', is still a very popular focus. His chaos - loving personality and his influence on Harley Quinn and other villains can be the center of many fanfictions. Additionally, characters like Bane, with his brute strength and intelligence, can be interesting to write about, especially if exploring his rivalry with Batman in the context of the Arkham assault.
Well, in batman and the justice league fanfiction, aside from Batman himself, The Flash is often a popular character to focus on. His super - speed can create all kinds of exciting plot twists, like being able to travel through time or dodge attacks in ways that seem impossible. Green Lantern is also great to write about. His power ring and the whole Green Lantern Corps lore can be delved into deeply. And of course, Aquaman, with his underwater kingdom and unique abilities related to the sea, can bring a whole new dimension to the fanfiction.
Superman is also a top pick. His superhuman powers and his moral compass often contrast with Batman's more grounded approach. A fanfiction could focus on their friendship or the occasional disagreements between them within the context of the Justice League.
Raphael could be really interesting. In the 2003 version, he is hot - tempered and tough. In the 2012 version, he also has a strong personality. Seeing how he reacts to his counterpart and how they might either clash or bond could be a great focus. Maybe they have a friendly rivalry as they compare their fighting skills.
Batman himself is very likely to be the focus. His actions and decisions during the aftermath would have a huge impact on Gotham. Also, Robin could be a central character, especially if the story is about the future of Batman's legacy. He might be stepping up more in Batman's absence or working closely with him to rebuild the city.
