In the X-Men comics by Jean Grey, Raven doesn't die. Her character has managed to overcome many threats and remain a vital part of the story. The plotlines often have her finding ways to escape or overcome potential death situations.
I really liked 'A New Perspective'. In this fanfic, the OC brings a fresh outlook to the X - Men universe, especially in relation to Jean Grey. It has some really interesting plot twists and character developments. The way the author portrays the connection between the OC and Jean is both engaging and thought - provoking.
The relationship between the OC and Jean Grey needs to be multi - faceted. It can't just be a simple friendship or romance. There should be conflict, mutual growth, and a deep understanding of each other's motives. In some great fanfics, they start off as adversaries and gradually come to respect and rely on each other. This kind of character arc makes the story engaging.
To write an engaging story with an OC, Jean Grey, and the X - Men in an animated fanfic, first, develop your OC's character thoroughly. Give them a unique backstory, powers, and personality. For example, if your OC has telepathy like Jean Grey, find a way to make it different. Then, focus on the relationships. Jean Grey has complex relationships within the X - Men. Your OC can interact with her in various ways, like being a mentee or a rival. Also, use the animated setting to your advantage. Incorporate the vibrant and dynamic nature of the animated universe into your plot. Maybe there's a big battle in the city, and your OC, Jean Grey, and the X - Men have to work together to save it.
For plot ideas, consider this: your OC has a power that is a mirror - image of Jean Grey's, but in a negative way. This causes conflict at first, but as they get to know each other, they learn to work together. Or perhaps there's a prophecy that involves both your OC and Jean Grey, and the X - Men are caught in the middle of it. They have to figure out how to either fulfill or prevent the prophecy. Another idea is that an alien race is interested in the powers of both your OC and Jean Grey, and the X - Men have to protect them from being abducted.
One possible fanfic could be about an original character who has a special connection with Jean Grey as Marvel Girl. Maybe the OC is a new mutant at the X - Men school and Marvel Boy, who is also there, starts to notice how the OC and Jean interact. The story could revolve around a mission where Jean's powers as Marvel Girl are crucial, and the OC and Marvel Boy have to learn to work with her.
Some of the X - Men might be very supportive. For example, Storm could be there for her as a sister - like figure, offering emotional support. However, others might be more cautious. Wolverine, known for his tough exterior, might worry about how the baby could be a potential target, and this could cause some tension in their relationship.
An OC could be a villain who has a vendetta against Jean Grey as Marvel Girl and sees Marvel Boy as an obstacle. This would create a lot of action and conflict in the fanfic. The OC could have unique powers that make it a challenging opponent for both Jean and Marvel Boy.
