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.
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.
A mature Jean Grey Wolverine fanfic often deals with complex emotions. Instead of just focusing on the surface - level attraction, it explores their deep - seated feelings like love, loyalty, and sacrifice. For example, a fanfic might show how Wolverine is willing to put his life on the line for Jean Grey not just because he loves her, but also because of his sense of honor.
One great fanfic could be 'The Unbreakable Bond'. It delves deep into the complex relationship between Jean Grey and Wolverine. The story is mature in the sense that it explores their emotional and psychological connection against the backdrop of the X - Men universe. It shows how they rely on each other during tough battles and how their relationship evolves over time.
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 contrast between them. Wolverine was this tough, rough - around - the - edges guy, while Jean Grey was elegant and powerful in a more refined way. Their love story was also full of unspoken emotions and longing, especially since Jean was with Cyclops. Wolverine's unwavering love for her despite the odds made it really compelling.
One great 'X - Men Jean Grey X OC fanfic' is 'The Unlikely Bond'. It focuses on an OC with telepathic powers similar to Jean's. Their initial encounters are filled with mistrust but gradually develop into a deep friendship and something more. Another one is 'Jean Grey's New Ally' where the OC helps Jean deal with her inner demons and the challenges of being an X - Man.
