One main theme is the concept of family. Since they are brothers in the fanfiction, it explores what family means to them, whether it's loyalty, protection, or something else. Another theme is the struggle between good and evil. Izuku is on the hero side and Shigaraki on the villain side, so there's this constant tug - of - war between their ideologies.
The themes often include redemption. Shigaraki, being a villain, may have a journey of redemption because of his connection to Izuku. Also, acceptance is a big theme. They have to accept each other despite their differences. In many of these fanfictions, they might have different Quirks or life goals, but they still have to come to terms with being brothers.
Identity is a significant theme as well. Both Izuku and Shigaraki have their own identities in the original story. But when they are made brothers in fanfiction, they have to re - evaluate who they are. Izuku might question his identity as a hero if his brother is a villain, and Shigaraki might struggle with the idea of having a heroic brother. It makes for some really interesting character exploration.
One common theme is the idea of redemption. Shigaraki, being a villain in the original context, showing protectiveness towards Izuku can be seen as a step towards redemption. It makes readers wonder if he can truly change.
One popular 'izuku and shigaraki are brothers fanfiction' is 'Brothers in a Twisted World'. It explores their relationship in a unique way, delving into how they might interact if they were brothers. It has some great character development and an interesting plot that keeps readers engaged.
Perhaps in the fanfiction, they are in a world where quirks don't exist yet. Baby Izuku and Shigaraki grow up in an orphanage. Izuku is always the one trying to cheer everyone up and bring people together. Shigaraki is more withdrawn but Izuku keeps trying to be his friend. As they grow older, events start to shape them in ways that are different from each other, leading to different paths that are still influenced by their early bond.
A lesser - known but really good one is 'Izuku Under Shigaraki's Guard'. It starts with Shigaraki being assigned to keep an eye on Izuku for some rather mysterious reasons. As the story progresses, Shigaraki's protective instincts kick in, and he has to fight both his own allies and enemies to keep Izuku safe. It's a great read for those who like exploring unique relationships in the fanfiction world.
One interesting plot could be that Deku and Shigaraki, as brothers, are on opposite sides at first. But then they discover a common enemy that forces them to work together. This would involve a lot of character development as they have to overcome their differences. For example, Deku's belief in heroism and Shigaraki's hatred for the hero society.
For allies, All Might could be an interesting choice even when they are babies. All Might might sense Izuku's potential and also see that Shigaraki could be redeemed if guided right. Another potential ally could be Aizawa. He could be the one who trains them in basic self - defense skills when they are kids. As for enemies, the League of Villains could be a problem for Izuku, as they might see him as a threat to their plans with Shigaraki. Also, some of the more evil - minded heroes who don't believe in second chances for villains like Shigaraki could be enemies.
To write their relationship realistically, you need to consider their personalities. Deku is kind - hearted and determined, while Shigaraki is more cynical and vengeful. So their interactions would be full of tension. For example, if they have an argument, Deku might try to reason with Shigaraki using his ideals, but Shigaraki would likely mock or reject them.
One common theme is identity. Since Tomura is male in the original, making her female in fanfiction often leads to exploring how this new identity affects her relationships and her role in the villainous world. Another theme is power. Writers often play with how a female Tomura might use or abuse her power differently.
One common theme is the exploration of his past trauma. Most of these fanfictions dig into what made him become a villain in the first place. Another theme is the power of forgiveness. Characters often have to forgive Shigaraki for his past deeds for his redemption to be possible.
One common theme is redemption. Often, the male reader is seen as a sort of guiding light for Shigaraki, leading him towards a path of redemption or at least a change in his ways. For example, in many stories, the male reader's kindness makes Shigaraki question his own violent actions.
