Well, perhaps the fanfiction could focus on how their relationship deepens during pregnancy. They might have more tender and emotional moments together. They could also be in a situation where they need to find a balance between their personal lives as expecting parents and their responsibilities in the larger context of their world. For instance, they may have to make difficult decisions about whether to continue with certain dangerous missions or stay back to ensure the safety of their unborn babies.
Perhaps a plotline could center around the Innocence within them reacting to the pregnancy. Maybe Lenalee's Innocence has some sort of special reaction, like providing an extra layer of protection. And Allen could have dreams or visions related to the future of their child, which could lead them on a new quest to understand what it all means in the context of the D.Gray - man world.
One possible plotline could be that they are in a dangerous situation together, and in a moment of relief after surviving, they share a kiss. For example, after fighting a particularly tough Akuma, the adrenaline and the realization that they care deeply for each other leads to that kiss.
Fanfiction about Allen and Lenalee being pregnant can be a creative take on the D.Gray - man universe. Some fanfiction writers might explore the medical aspects, like how the pregnancy would affect Lenalee's Innocence. Others might focus on the emotional journey of Allen and Lenalee. They would need to face the challenges not only from the Akuma but also from the fact that they are about to become parents. It could be a story full of love, worry, and hope, which is quite different from the main plot of the original manga.
Allen in these fanfictions is typically a complex character. He has his own goals related to the Millennium Earl and the Akuma, but his feelings for Lenalee add another layer to his personality. He might be hesitant in expressing his emotions at times. Lenalee, on the other hand, is very empathetic. She is able to sense Allen's pain and tries to ease it. Their relationship in the fanfiction is usually based on mutual understanding and a growing, unspoken love that gives both of them something to fight for.
Lenalee might become more protective and nurturing. Since she has always been strong - willed, pregnancy could bring out her softer side even more. She may start to see the world in a different light, focusing more on creating a safe and loving environment for her child. Allen, on the other hand, could develop a new sense of responsibility. He might be a bit more cautious in his actions as he now has a family to think about.
One great allen and lenalee fanfiction is 'The Bond Beyond Duty'. It beautifully explores their relationship as they face various challenges in the D.Gray - Man universe. The story delves deep into their emotional connection and how they support each other during tough times.
One possible plotline could be the two characters supporting each other through their pregnancies. They could share their experiences, like dealing with morning sickness. For example, Lucy might use her celestial magic in unique ways to soothe the discomfort, while Juvia's water - based magic could also have some interesting interactions related to her pregnancy. Another plotline could involve their partners' reactions. If we consider their respective love interests, how would Natsu and Gray respond to the news? They might be overjoyed but also a bit nervous, and there could be some comical moments as they try to be helpful but end up making a bit of a mess.
A plotline could involve the health - related aspects during the pregnancy. Conner and Kira could be going to doctor's appointments together, and there could be some minor scares or concerns about the baby's health. Also, they could start thinking about the future of the child, like what kind of education they want to provide, which could lead to some discussions and even small arguments between them.
One possible plotline could be that through some sort of time - travel magic, Hermione goes back in time and meets Salazar. They fall in love in a very unexpected way, and then she becomes pregnant. The story could then focus on how she tries to adapt to the ancient wizarding world while being pregnant and dealing with the differences in magic and society from her own time. Another plotline might be that Salazar somehow returns to the modern day in a spirit or reincarnated form, and he and Hermione form a connection that leads to her pregnancy, and the story could explore how the wizarding community reacts to such a strange union.
One possible plotline could be the challenges they face in preparing for the baby. They might struggle with announcements to the public and dealing with the media frenzy. Another could be how their relationship changes as they anticipate the arrival of the child, with Maxon becoming even more protective of America.
