Yes, it is. Their complex relationship adds a lot of depth to the Batman storylines. Catwoman is often portrayed as a love interest for Batman, with their cat - and - mouse dynamic being both romantic and adversarial at times.
A really good fanfiction could be centered around a time when Nightwing doubts his place in Batman's life. Batman then has to prove to Nightwing that he is like a son to him. This could involve Batman opening up about his own fears and insecurities, which is not something he usually does. It would make for a very interesting read as it shows a different side of their relationship.
Yes, it is quite popular. Many fans are intrigued by the idea of Supergirl and Batman in a romantic relationship. They enjoy exploring the dynamic between the two powerful characters from different backgrounds. The contrast between Supergirl's more idealistic and hopeful nature and Batman's darker, brooding persona makes for an interesting romantic concept in fanfiction.
It's not common in the sense that it goes against the norm. In most official Batman storylines, Batman is the symbol of justice that endures. However, in the realm of fanfiction, some writers explore this dark and edgy concept to explore different character arcs, power dynamics, and moral ambiguities. It challenges the established order and makes readers question their assumptions about the characters.
One reason could be that you simply have no interest in the combination of Snape (from Harry Potter) and the Batman theme. Maybe you prefer to keep the two universes separate in your mind. Another reason might be that you find it difficult to come up with a coherent and engaging story that blends these two very different concepts.
Yes, there could be. For example, a story could be about the Mad Hatter trying to use mind control on Alice, and Batman comes to her rescue. Batman uses his detective skills to figure out the Mad Hatter's plan and stops him from controlling Alice's mind. It could be a story of good versus evil, with Batman as the hero protecting the innocent Alice from the devious Mad Hatter.
Not exactly. Batman Begins is one interpretation of Batman's origin story, but it's not the definitive or only 'real' one. Different Batman stories and adaptations offer various takes.
It might be significant as it could show the rebirth of Batman, perhaps with a new take on his character. It may also explore the relationship between Batman and Robin in this new phase.
One possible aspect of a Batman and Harley fanfic in the Arkham universe could be their complex relationship. Batman is always trying to uphold justice, while Harley is often caught between her love for the Joker and her own sense of right and wrong. In a fanfic, the author might explore how Batman could potentially save Harley from her self - destructive path. For example, Batman could use his detective skills to show Harley the truth about the Joker's abuse towards her.
