His anger might push his friends away at first. They might not understand why he's so angry and be put off by his sudden outbursts. For instance, if he snaps at Aqualad or Superboy, they could be taken aback and become a bit distant.
With the other members of Young Justice, his injury could bring out their more nurturing sides. They might take turns looking after him, which could strengthen their bonds. On the other hand, some might see him as weakened and question his leadership abilities if he was in a leadership role before. For instance, Aqualad might have to step in more often to lead missions, causing some tension between them as Robin recovers.
The Young Justice team members would also be severely affected. Superboy might become more reckless in his actions, feeling that he should have been able to protect Robin. Aqualad could struggle with feelings of guilt for not having made better strategic decisions during the mission that led to Robin's death. And the team as a whole might become more fragmented as they each deal with their grief in different ways.
One possible reason could be betrayal. If a teammate in the Young Justice team were to go behind his back or break his trust, Robin would get mad. He's a character who values loyalty highly.
With his mentor or teacher figure, the dynamic would shift. Instead of being the student who is learning, Robin as a kid might be more in need of basic life lessons. His friends who were used to his equal partnership would now have to be more patient and understanding. They might find his child - like innocence endearing but also frustrating at times. And his relationship with any rivals could become more complex as they might not know how to deal with a kid version of him.
Robin's self - harm can be a major turning point in the fanfiction. It could lead to a deeper exploration of his character, his past traumas, and how he copes with stress. This in turn can influence the overall plot, as the team may need to take time to help him, or his self - harm could be related to a larger threat they are facing. Also, it might affect the tone of the story, making it darker and more serious.
He would interact more openly. For example, with Batman, there could be a different dynamic. Batman might be more protective as Robin is now more vulnerable without the mask. Robin, on the other hand, might feel more like an equal as he's showing his true face. With his friends in Young Justice like Superboy, he could be more relaxed. They might tease him about his new 'open - face' hero status, but also support him more directly in battles as they know he doesn't have the added protection of anonymity.
Obviously, the main character would be the one who would become Robin. But there could also be other important characters like his trainers or guardians. For example, an old martial arts master who taught him the ways of combat.
It might make his relationship with his friends a bit strained. For example, Hermione and Ron might not understand his anger at first and try to convince him that his parents were heroes. This could lead to some arguments between them.
Some students might be afraid of him. His sudden outburst of anger could make him seem intimidating. So, they would keep their distance from him.
In some Young Justice fanfiction, Robin might be depicted as killing, but this goes against his traditional non - killing code in the mainstream series. However, in fanfiction, authors may explore 'what - if' scenarios. For example, in a darker, alternate universe - type fanfic, Robin could be pushed to the edge and take a life in self - defense or to protect his team. But it's important to note that this is not in line with the character's typical portrayal in the official Young Justice series.
