One possible plotline could be that the Avengers are under the influence of a mind - controlling villain. They turn on Steve because he's seen as a threat to the villain's plan at that moment. Another could be a misunderstanding. For example, false evidence is planted that makes the Avengers believe Steve has betrayed them, so they accidentally hurt him while trying to stop what they think is his betrayal.
In some fanfictions, the Avengers might be facing a situation where they have to make a difficult choice. They think sacrificing Steve's well - being is necessary for the greater good. So, they end up hurting him in the process of making that tough decision. For instance, if there's a powerful energy source that needs to be contained and Steve is in the way, they might move him forcefully, causing him injury.
One possible plotline could be how the other Avengers react to Steve's death. Some might go into deep mourning while others could be driven by revenge. For example, Tony might use his technology to try and find out who was responsible and bring them to justice.
One common plotline is Steve struggling with a mysterious illness while still trying to lead the Avengers. For example, he might be hiding his condition from his teammates because he doesn't want them to worry or think he's unfit for duty. Another could be that the illness is somehow related to a new enemy or a past mission. Maybe an experiment gone wrong during the super - soldier serum creation is starting to have side effects on him years later.
One possible plotline could be Loki initially being angry and resentful towards Thor for hurting him. But as the story progresses, Thor's guilt drives him to make amends in a big way, like going on a dangerous quest to find a rare healing item for Loki. This could lead to a deeper understanding between them and strengthen their bond in the end.
One interesting plot could be Steve adjusting to the new, younger body while still having the mind of an older hero. He might struggle with modern technology even more than before, leading to some comical situations. For example, trying to figure out a smartphone or a new type of vehicle.
One possible storyline could be that the Avengers are under some form of mind control. Maybe a powerful villain has manipulated them into believing Tony is a threat to the world. So, they start to target him, causing both physical and emotional harm. For example, they might break into his workshop and destroy his latest inventions, which are not only his creations but also his passion.
Maybe in a dark turn of events, Draco is under the influence of some dark magic or a curse that makes him act out against Ginny. She becomes a target because she is associated with Harry and the resistance against the Dark Arts. In this plot, Draco would struggle to break free from the control and Ginny would have to be the bigger person in the end.
Perhaps there's a mission where Kakashi and Sasuke are on opposite sides. Kakashi is following the orders of the village, and Sasuke is following his own path for revenge. In a confrontation, Kakashi uses his Sharingan - based techniques against Sasuke. Sasuke, not fully prepared to face Kakashi at that level, gets hurt. This would add more complexity to their relationship as teacher and student.
One reason could be exploring the moral complexity within the Avengers. Maybe they're mind - controlled or misinformed, which leads to them hurting Peter. It shows that even heroes can make mistakes and how they deal with the aftermath.
One interesting plotline could be Wolverine having to team up with the Avengers to stop a powerful mutant - created virus that threatens to wipe out both mutants and non - mutants alike. He brings his unique combat skills and healing factor to the table, while the Avengers contribute their various superpowers and high - tech resources.
One interesting plotline could be the return of a long - lost Avenger who has been in hiding or captivity. For example, they might come back with new powers or a different perspective, causing a shift in the team dynamics.
