Writers might describe his body language. Izuku could slouch more, keep his head down, and avoid eye contact. His smile, which is usually bright, could disappear or become forced. In the dorms at UA, he might isolate himself in his room for long periods. He may also start to neglect his hero training, which was previously something he was passionate about, as his depression saps his energy and enthusiasm.
They may depict him having internal monologues full of self - loathing. For instance, he could constantly think that he's a failure or that everyone would be better off without him. His eating habits might change too. He could either lose his appetite and start skipping meals, or overeat as a form of comfort. In battle, his performance might decline as he lacks the usual drive and confidence, and is more likely to make mistakes.
A frequent theme is his relationship with All Might. In some fanfictions, he might feel that he has let All Might down. All Might's high expectations of him could weigh heavily on Izuku, making him feel like he can't live up to them. This could lead to a downward spiral of depression. Also, the theme of hero society's pressure on him is common. The expectation to always be strong and save others can be overwhelming, and in these fanfictions, Izuku might crack under that pressure.
They could both develop their teamwork skills. In fanfiction, they might be put in various dangerous situations that require them to rely on each other. Izuku learns to better incorporate Melissa's support items into his fighting style, and Melissa learns how to adjust her items based on Izuku's needs and fighting style at the moment. This back - and - forth development makes their characters more well - rounded.
Well, in many of these fanfictions, Izuku's injuries show his vulnerability. This makes him more relatable as a character. We see that even though he has great power, he's still human and can be hurt. It adds depth to his character.
In many fanfictions, Izuku and the Hero Killer have a complex relationship. Sometimes, Izuku might be portrayed as trying to understand the Hero Killer's motives, which are often misconstrued but rooted in a desire for 'true' heroism. This can lead to some really interesting character development for Izuku as he grapples with his own ideas of heroism in the face of such a radical view.
Often, Izuku reacts with shock and disbelief at first. He can't fathom why someone he trusted would turn on him.
In fanfictions, their team - ups can be portrayed in various ways. Sometimes it's a forced alliance due to external circumstances, like a greater threat that endangers both heroes and villains. Other times, it could be a result of a mutual understanding that develops over time. For example, they might realize that the system they are both a part of (the hero - villain dynamic) has flaws.
One popular overpowered Izuku fanfiction is 'One for All: Unlimited'. In this, Izuku has an extreme version of One for All that gives him near - godlike powers right from the start. He's able to take on villains with ease that would normally be a huge threat in the canon story.
In these fanfictions, Izuku often develops more confidence in his relationships. For example, he may start off shy around the girls in his harem but gradually become more assertive. This is because the support and love from his harem give him an extra boost.
Well, it makes it a lot more challenging. He has to rely on different skills. For example, he can't just see an opponent's attack coming like before. He has to use his sense of touch more, like feeling the air currents change when someone is about to strike.
One common theme is Izuku's power growth. In many of these fanfictions, he becomes even more powerful and badass in unique ways compared to the original story. Another theme is his relationships, like his friendships or rivalries. For example, his relationship with Bakugo might be explored differently, showing how his badass side affects it.
