One possible fanfic plot could be that Eren has been planning this for a long time. He might gather intelligence about the Colossal Titan's weaknesses. Then, in a fierce battle, he manages to get close enough to deliver a fatal blow. This could be a very emotional moment for him as well, considering the history between them.
Well, sometimes he uses his titan's speed and agility to dodge the Colossal Titan's attacks and then strike at its nape. It's a classic way to take down a titan in the Attack on Titan universe.
One possible plot twist could be how his relationships change. For example, his friends might react with shock and confusion at first. Mikasa might have a whole new set of emotions to deal with, like a different kind of protectiveness. Also, the military might view him differently. They could be hesitant to send a 'female - Eren' into battle at first, or they might use his new form to their advantage in different ways, like using his appearance to deceive the Titans.
One popular fanfiction idea could be a story where Eren has to team up with the Female Titan against a new, more powerful enemy in the world of Attack on Titan. Maybe they start off as reluctant allies, but as they face challenges together, they begin to understand each other better and develop a unique bond.
Well, his character development could take a whole new turn. Eren is known for his aggression and determination as a male. As a girl, he might have to find new ways to express those traits. He could become more empathetic as he experiences different forms of discrimination or treatment. Also, his relationships with his male friends could become more complex. They might see him in a new light, and he might have to re - evaluate his own self - worth in relation to how they now view him. His development could also be influenced by how he copes with his new physical form and the limitations or advantages it might bring in the fight against Titans.
Krista's significance in 'Attack on Titan' lies in her ability to surprise the audience with her hidden identity and her growth throughout the story. Eren, on the other hand, is crucial as he is the catalyst for many of the major events. His relationship with Krista is part of the web of character interactions that make the story so engaging. They both contribute to the overall theme of survival and the exploration of the truth about the Titans. Krista's character arc is also linked to the broader political and social aspects of the story, just like Eren's actions are tied to the fight against the Titans.
One common theme is the struggle for identity. Eren being a titan makes him question who he really is. Is he still the same Eren or has the titan side changed him completely?
Well, it all happened when Eren got hold of that special serum. When he used it, it activated a genetic trait within him, allowing him to transform into a Titan. It was a crucial moment in the story that changed everything for him.
Love and friendship are also prevalent themes. Despite their differences and the initial hostilities between them, they might develop a deep friendship or even romantic feelings. This can add a whole new layer of complexity to the relationships in the Attack on Titan world. For instance, they could be the key to uniting different factions within the story that were previously at odds because of their relationship.
