One idea could be that Batman discovers the reader is pregnant and he struggles with how to protect both her and the unborn child while still fighting crime in Gotham. He might become even more vigilant and start to plan for a safer future for his new family.
I would recommend 'Batman's Unlikely Ally'. In this fanfic, the reader is a normal citizen who unexpectedly becomes important to Batman's fight against crime. It's filled with action scenes and some really sweet moments between the two characters. The way the author describes the relationship development is quite interesting.
First, understand Batman's character. He's a complex, brooding hero. Then, create a unique reader character that can interact with him in an interesting way. For example, make the reader have a special skill or knowledge that Batman needs. Also, set the story in Gotham and include elements like the city's crime and its dark alleys.
One common theme is the idea of the speed reader being a unique asset to Batman's crime - fighting. Maybe they can quickly analyze evidence or decrypt messages at a super - fast speed. Another theme could be the relationship dynamic, like the speed reader being in awe of Batman's skills and Batman being intrigued by the speed reader's special ability.
First, you need to establish the characters. Decide on the personality of the reader character, whether they're strong - willed, shy, etc. For Batman, stay true to his core characteristics like his intelligence and determination. Then, create a setting. It could start in Gotham city, perhaps at a crime scene where the reader witnesses Batman in action. Next, build the relationship gradually. Don't rush into the romantic or more intense parts right away.
Well, first of all, some dedicated Batman fan communities might also have fanfiction about this pairing. For example, on Reddit, there could be specific Batman - related subreddits where fans share or discuss such fanfictions. Another option is to follow some Batman or fanfiction - focused Tumblr blogs. They sometimes reblog interesting fan - made stories, and you might stumble upon the batman x speed reader ones.
One popular trope is the 'forbidden love' aspect. Since Batman is often portrayed as a brooding and dedicated hero, a relationship with the reader character can be seen as something he shouldn't have due to his commitment to Gotham. Another is the 'protective Batman' trope. He will go to great lengths to protect the reader from the various villains in Gotham. Also, the 'discovery of identities' can be a common trope, where the reader might find out Batman's true identity in a dramatic or unexpected way.
A third common theme is the exploration of Alfred's past. In some fanfictions, the Reader might be the one to uncover secrets about Alfred's life before he came to work for the Wayne family. This can add depth to their relationship as they bond over these revelations. It also gives the writer a chance to expand on the lore of the Batman universe in relation to Alfred's character.
A great Batman TAS Jervis Tetch x Reader fanfiction is one that can make you feel like you're part of the story. The writer should use vivid descriptions, not just of the physical appearances but also of the emotions. The story could incorporate some of the iconic elements from Batman TAS, like the art style or the other characters. This adds depth to the fic. It should also handle the psychological aspects of Jervis Tetch well, as he is a complex character. If the fic can explore his motives and how they interact with his relationship with the reader, it's more likely to be a great piece of fanfiction.
Another option is Tumblr. There are many fanfiction writers who post their Alfred x Reader Batman works on their blogs. You can search for relevant tags or join Batman fanfiction communities on Tumblr where people often share and recommend such stories.
