Well, it really depends on the specific fanfiction. Some fanfictions do make Ichigo overpowered. They might do this to explore different storylines or just for the fun of it. For example, in some, he could have a sudden boost in his reiatsu that makes him almost unbeatable. But not all fanfictions take this route. There are also those that focus on his character development in a more realistic way within the context of the Bleach universe and don't make him overly powerful.
It could be a sword that can cut through any substance, like the Susanoo easily. Just imagine Naruto swinging it and slicing through powerful jutsu defenses as if they were paper.
One possible aspect to consider in 'natsu overpowered fanfiction' is how it changes the power dynamics within the original story's universe. If Natsu is made overpowered, it can lead to different plot developments. For example, battles that were originally challenging might become one - sided, which could either make the story more exciting as we see Natsu's dominance or less engaging if the conflict is too easily resolved. Also, it might affect the relationships between characters. Other characters may start to view Natsu differently, either with awe or envy. This can create new story arcs centered around these changed relationships.
Captain Marvel has impressive abilities, but whether she's overpowered is subjective. It varies based on the comic's plot and the opponents she's up against. In some cases, she might seem too strong, but in others, she faces tough opposition that balances things out.
Another aspect is prior knowledge or experience. In some light novels, the MC is reincarnated or transferred from another world. Like in 'Konosuba', Kazuma has knowledge from his previous life which he uses to his advantage in the new world, and this knowledge combined with his unique skills makes him overpowered in certain situations.
The hero might be overpowered due to some special abilities or powers he was born with or acquired. For example, he could have super strength, magic powers, or extraordinary intelligence. And he is overly cautious perhaps because he has experienced great losses in the past when being reckless. So now, even with great power, he still thinks twice before acting to avoid repeating the same mistakes.
It could be that the nature of the world in the light novel is very unpredictable. There could be hidden enemies or powerful forces that even an overpowered hero would be wary of. So, in order to protect themselves and those they care about, they choose to be cautious. For example, there might be ancient curses or prophecies that target powerful individuals like the hero. And the hero, being aware of these potential threats, acts with caution.
Well, it could be his strategic mind. Ikki Kurogane might be able to analyze complex game scenarios and come up with brilliant strategies on the fly. For example, in a team - based game, he can quickly assess the strengths and weaknesses of both his team and the opponents, and then direct his team to victory. His ability to think several steps ahead makes him overpowered as a gamer in the fanfiction.
One of the overpowered Chinese novels is 'Martial World'. The protagonist in it has amazing growth and power - up systems, with constantly evolving martial arts skills and the ability to defeat opponents far stronger than himself at times.
