On the other hand, it could strengthen her bond with some characters. For example, if there's a scientist character who helps her understand and control the absorbed energy, their relationship would grow closer.
It could make her more distant from her friends. If she absorbs a powerful and dangerous energy, she might be afraid of hurting them, so she keeps her distance.
Her speed could make her seem distant to her friends and allies. Since she can move so fast, they might feel like she's always in a rush and not fully present in their interactions. For example, she could quickly say goodbye and be off on another mission before they even finish their conversation.
Her relationship with her ANBU subordinates would be complex. On one hand, she would be their strict leader, but on the other hand, she would also be someone who cares deeply about their well - being. She might have to make tough choices that some of them don't like at first, but over time, they would come to respect her and her decisions.
She could meet a very smart science teacher who is intrigued by her powers and wants to study them scientifically.
One way could be through some sort of time - travel or alternate reality plot. For example, if there was a situation where Captain Marvel went back in time and became involved with Peter Parker's father, or if an alternate reality had different rules of genetics and relationships. Another way could be a magical or alien - influenced situation where Captain Marvel was somehow magically linked to Peter Parker's creation in the fanfic world.
He could inspire them. Captain Marvel's strong sense of justice and his amazing powers can be a source of motivation for the sad Young Justice members. Just seeing someone so powerful yet still fighting for good can lift their spirits.
If Cortana becomes human, her relationships would change drastically. Her relationship with her former AI colleagues or creators would become more complex. She would no longer be just a program they can control or upgrade. Instead, she would be an equal, which could lead to some power struggles or awkward moments.
Her relationship with Ron and Harry would be strained at first. They'd feel betrayed that she left Hogwarts. But over time, they might come to understand her reasons. At Durmstrang, she'd have to build new friendships. She might befriend some students who are more interested in academic pursuits like her. Her relationship with the professors at Durmstrang would also be different. Some might be more strict and traditional, while others might see her potential and encourage her studies.
A possible plot could be that an ancient artifact has been stolen and it has the power to disrupt the balance between Earth and Asgard. Captain Marvel and Valkyrie are both called upon to retrieve it. They initially suspect each other of having ulterior motives but soon realize they are on the same side. They then embark on a journey filled with battles against various intergalactic pirates and magical creatures who also want the artifact for themselves.
She could simply overpower Thanos. Captain Marvel has shown incredible strength, so she might be able to directly take on Thanos and win in a one - on - one fight, preventing him from snapping his fingers.
In relation to Black Widow, they could form a stronger bond. Black Widow might see in her a kindred spirit, now that they are both female superheroes. They could train together more often, share secrets about being a woman in a tough superhero world, and team up more effectively during missions.
