Well, in the fanfic, Bruce would probably become more withdrawn. He'd brood over Jason's death, questioning his methods and his role as a mentor. Dick would be angry at the world, especially at the villains who might have been involved. Tim, on the other hand, would be more determined to prove that he can be a worthy Robin, but also carry the pain of losing Jason. Alfred would be the one constant, trying to comfort everyone with his wisdom and care. It's a really tragic event for the Batfamily and their reactions would be complex and full of emotions.
Dick's reaction is also very sad. He was close to Jason and to see him die would be like losing a part of himself. He might become more reckless in his actions, trying to avenge Jason, which shows how deeply affected he is.
Jason Todd's death in fanfics is like a bomb that explodes within the Batfamily. For the Batfamily, it changes the whole dynamic. Alfred, for instance, is deeply saddened and tries to hold the family together while also mourning privately. Barbara Gordon, who has her own connection to the family, may see the danger of their vigilante lifestyle more clearly. And the new Robin, whoever that may be, has to carry the weight of living up to a legacy that ended so tragically. It's a complex web of emotions and changes that the fanfics explore in great detail.
In many fanfics, the Bat Family is often devastated. Bruce might be filled with guilt, blaming himself for not being able to protect Jason. Dick could be angry and determined to find out who was responsible. Tim might feel a sense of loss and also a strange connection to Jason, as he took on the Robin mantle after him.
One great 'Batfamily Jason Todd Death' fanfic is 'Under the Red Hood'. It delves deep into the aftermath of his death and how it affects the Batfamily. The story shows the complex emotions of the characters, especially Batman's guilt and how it changes his relationship with the other members. Another interesting one might be those that focus on how Jason's death haunts the younger members of the Batfamily who grew up hearing about him.
Annabeth might be annoyed. She's very perceptive, so she quickly realizes Jason's jealousy. She'll probably tell him directly to stop acting childish and respect her relationship with Percy.
One of the best batfamily moments in fanfic is when they all come together for a family dinner. It shows their different personalities interacting in a normal, non - crime - fighting setting. Dick is cracking jokes, Jason is brooding but still participating, Tim is being the smart one with some tech talk, and Damian is reluctantly joining in. It gives a sense of family and normalcy that is often lacking in their vigilante lives.
The moment when the younger members of the batfamily look up to Bruce as a father figure is really heartwarming. In fanfic, it can be shown in small gestures like Bruce teaching them how to fix a car or cook. For Damian, it could be Bruce patiently guiding him through his emotions, which is a big step for Damian as he's not used to such emotional openness. It shows the family bond growing.
Guilt is a big one, especially for Bruce. He might think he failed as a mentor. Sadness is also prevalent. They all lost a family member. Anger too, towards the ones who caused Jason's death.
Twilight Sparkle would probably be devastated. She looked up to Celestia as a mentor, so she might go into a state of deep mourning at first. But then, she could be motivated to try and fill the void Celestia left, using all the knowledge Celestia had imparted to her.
Jason might be shocked at first. He could feel a sense of respect for Percy, knowing that those scars are the marks of his many battles and hardships. Maybe he would be more curious about Percy's past adventures that led to those scars.
