Well, obviously the two main characters are Batman from the normal DC universe and Flashpoint Batman. Batman is the well - known Dark Knight, a symbol of justice in Gotham. Flashpoint Batman is from an alternate timeline, with different experiences and a potentially different personality.
Another idea might be that one Batman is from the future and has come back to meet his past self. The future Batman could show the past version some new technologies and tactics, but also warn him about the potential consequences of certain actions. This could lead to self - reflection for the past Batman and a change in his approach to crime - fighting.
To develop the characters in 'Sofa Meets Godzilla' fanfiction, consider their backstories. The sofa could have been part of a family's home for generations and has seen a lot of human emotions, which makes it empathetic. Godzilla's backstory of being a product of nuclear radiation can be delved deeper into. What if there are parts of his past that he doesn't remember? And how does the sofa's presence stir up old memories or emotions? By exploring these aspects, the characters become more interesting and relatable.
Sasuke would likely be aloof and guarded at first. He might see Batman as just another 'vigilante' like some of the shinobi in his world. Batman, on the other hand, would be cautious and try to figure out Sasuke's motives. Eventually, they could start sharing their combat techniques. Sasuke might show Batman how to use chakra in combat, and Batman could teach Sasuke about the importance of having a strong moral code.
One possible scenario in this fanfiction could be that Tim Drake initially looks up to Batman from afar. He might be in awe when he finally meets him, perhaps during a crime - fighting situation. Tim could be trying to prove himself to Batman, showing off his detective skills that he has honed over time.
The plot might involve the human boy being in the wrong place at the wrong time and getting caught in the middle of a battle between Godzilla and another kaiju. Godzilla notices the boy and decides not to let him get hurt. This starts a journey where the boy and Godzilla have to rely on each other. The boy might use his knowledge of the human world to help Godzilla find a way to defeat the other kaiju, like leading it to a place where the kaiju's powers are nullified.
The allure of a Pokemon Godzilla fanfic lies in the combination of two very popular and distinct universes. For example, imagine a story where Godzilla is a Pokemon that only awakens during times of great imbalance in the Pokemon world's energy. Trainers from all over would then be in a race to either befriend it or prevent it from causing too much destruction.
Another plot development could be that Flashpoint Batman tries to convince the regular Batman to change his ways. He might see the regular Batman's methods as too soft or ineffective. This could create a lot of internal conflict for the regular Batman as he questions his own beliefs and methods in the face of this alternate - self's criticism.
Perhaps they could start off as rivals in the fanfiction. Batman from the present is skeptical of Batman Beyond's more high - tech approach. But as the story progresses, they learn from each other and become a great team. For example, Batman could teach Batman Beyond some of his old - school detective skills, while Batman Beyond shows Batman new ways to use technology in combat and surveillance.
Robin could be a great addition. He could act as a bridge between Starfire's more light - hearted nature and Batman's seriousness. His acrobatic skills and detective training could complement both of them in a fight. Another good character would be Nightwing. He has a connection to Batman already and his charm could add an interesting element when interacting with Starfire.
