One possibility could be Eren. Given their long - standing relationship and the strong bond they've had throughout the story, it's not a far - fetched idea that he could be the father.
Maybe a group of outcasts from outside the walls. They could have heard of Mikasa's strength and think that by kidnapping her, they can gain some sort of leverage over the people within the walls. They might be desperate for resources or a place to live and believe that Mikasa is their ticket to getting what they want.
One idea could be that in a post - war world, Mikasa discovers she's pregnant. She then has to deal with the challenges of raising a child in a world that's still rebuilding. She might worry about how to protect her child from the remaining threats.
One common theme is the exploration of new worlds. Mikasa is often thrust into different settings, like a futuristic sci - fi world or a magical realm. Another theme is her adapting to new cultures and societies. For example, in crossovers with more peaceful worlds, she has to adjust her combat - ready mindset. And of course, there's the theme of forming new relationships, whether they be friendships or rivalries.
It's not okay. Mikasa Ackerman is a well - known character from 'Attack on Titan'. Fanfic should be about exploring the character's story, personality, relationships in a positive and appropriate way, not with sexual themes. This kind of content also goes against the general moral and ethical standards in the fan community.
It could also be someone new, a character created specifically for the fanfiction. Maybe a powerful new demigod who catches Annabeth's eye, and their relationship leads to the pregnancy.
It could be a long - lost love from Mavis's past. Maybe someone she thought she'd never see again but who re - enters her life right before she discovers she's pregnant.
It could be another powerful magical being in her realm. Maybe a long - time ally or a mysterious figure that has been in the background of the story's world. This would add an element of mystery and intrigue to the fanfiction.
In some fanfictions, the father could be a human character. This would add an interesting dynamic as it would involve dealing with the differences between a human and a Digimon in a relationship and during pregnancy. It could also lead to a story about acceptance and dealing with the unconventional nature of such a union.
It could be one of her close friends or classmates in 90210. Maybe someone she had a brief fling with during a party or a school event.
Maybe it's a new character introduced just for this plot twist. This would add an element of mystery and new drama to the story.
