The theme of family and legacy might also be prominent. Eren and Mikasa's relationship has always been complex, and with a pregnancy, it adds a new dimension to their family dynamic. Fanfics might explore how they plan to raise their child, what values they want to pass on, and how their family will contribute to the future of the world they live in. This can be especially interesting considering the post - apocalyptic setting of 'Attack on Titan'.
I'm sorry, I can't directly recommend specific 'Mikasa Eren' fanfics where Mikasa is pregnant. However, you can try searching on some well - known fanfic platforms like Archive of Our Own (AO3). They have a vast collection of fanfics, and you can use the search filters to look for ones related to this specific scenario.
Annie is often depicted as a more reserved and calculating character. She keeps her emotions in check and is very strategic in her actions. Mikasa, on the contrary, is more passionate and driven by her love and loyalty. She is protective and doesn't hesitate to jump into action when needed.
In fanfiction, Mikasa and Jean often have their characters explored in different ways. Sometimes, their relationship can be developed into a deep friendship. Jean might be shown as having a newfound respect for Mikasa's strength and determination. This can add new layers to their interactions within the fan - created storylines.
In these fics, Sakura often becomes badass through intense training. She realizes that she needs to be stronger to change things in Konoha or to prove herself. For example, she might train under a mysterious master or in isolation, like in 'Sakura's Solitary Training' where she spends months alone in the forest, honing her skills.
One great book with badass fictional characters is 'The Lord of the Rings' by J.R.R. Tolkien. Characters like Aragorn are badass. He's a skilled warrior, a natural leader, and has the courage to face the dark forces of Sauron. Another is 'Harry Potter' series by J.K. Rowling. Harry himself is a badass as he battles the powerful and evil Voldemort throughout his life at Hogwarts and beyond, not to mention his friends Hermione and Ron who are also very brave. Then there's 'The Hunger Games' by Suzanne Collins. Katniss Everdeen is extremely badass. She volunteers for the Hunger Games to save her sister and shows remarkable survival skills and defiance against the Capitol.
