In a more emotional plot, Danny has lost his family in some ghost - related incident and is all alone. Batman, seeing a kindred spirit in Danny (both having experienced loss), decides to adopt him. Danny then has to adjust to living in the Batcave and being part of Batman's crime - fighting family. He struggles with fitting in at first but eventually finds his place and becomes an important asset to the team, using his powers in ways Batman hadn't thought of before.
His ghostly wail, a very powerful attack, could be used as a last - resort weapon against powerful foes in the Batman universe. However, it also might attract unwanted attention from other supernatural entities. Danny would have to learn to control it better in the more urban and populated Gotham. This would add an interesting dynamic to the crime - fighting in Gotham as they would have to deal with the potential consequences of using such a powerful ability.
Jason Todd would likely cross paths with Doctor Strange. Their worlds are very different, with Jason being more of a street - level fighter and Doctor Strange dealing with magic and otherworldly threats. But their encounter could lead to Jason learning about different forms of power and Strange might be interested in Jason's tenacity and willpower, which could be useful in his own battles against the forces of the dark dimension.
Another possibility is that he's facing some emotional turmoil. Danny has a lot on his plate. He has to keep his identity a secret from his friends and family, deal with school, and fight ghosts. All this stress could be causing him to lose his appetite. He might be too worried or preoccupied to even think about food.
One possible story could be that Danny is facing a new and extremely powerful ghost. He needs help from his friends Tucker and Sam. Maybe they need to find a rare artifact to defeat this ghost. They could start by researching in the local library, looking through old ghost lore books. Tucker uses his tech skills to try and track down any leads on the artifact's location, while Sam uses her knowledge of the occult.
In fanfiction, Jason Todd and Black Mask often represent two opposing forces. Jason Todd, with his complex past and moral code, can be pitted against Black Mask's villainy in various ways. For example, some fanfictions might focus on Jason's quest for justice and how it intersects with Black Mask's criminal activities.
A popular one is 'Jason Todd's Journey through the Arrowverse'. In this fanfiction, Jason Todd crosses over into the Arrowverse. It delves into how he would fit into that world, his interactions with the Arrow characters, and how his presence might change the dynamics of the storylines there.
No, it's not that common. While there are various types of fanfiction exploring different aspects of Jason Todd's character, fanfiction that focuses on abuse is a more niche and often controversial area. Most fans are more interested in his heroics, his relationships in a positive light, or his backstory in terms of his training and development as a character.
One interesting story could be about Danny and Sam going on a ghost - hunting adventure together. They might discover a new type of ghost that has unique powers and they have to figure out how to defeat it using their combined skills.
Sam is also quite popular. Her goth - like personality and her strong - willed nature make her an interesting character. In fanfiction, she can be portrayed in different ways, like being even more involved in Danny's ghost - fighting activities.
