A popular plot is the 'transfer of power'. Imagine if a Death Note somehow made its way into the My Hero Academia world and a hero or villain got hold of it. They would then have to figure out how to use this new power within the context of their existing powers and the society they live in. Another plot is the 'moral dilemma' plot. A character, whether a hero or a villain, is faced with the choice of using the Death Note for what they believe is right, but they have to deal with the consequences and moral implications, much like Light did in Death Note.
Sure. You can find them on various fanfiction websites. Look for ones that have high ratings and good reviews. Some might focus on crossovers where the characters from Death Note interact with those from My Hero Academia in unique scenarios. It could be a hero from My Hero Academia trying to stop someone misusing a Death Note - style power, or a Death Note character being influenced by the hero - centric society in My Hero Academia.
They can be blended by borrowing the concept of intelligence and strategy from Death Note. In My Hero Academia, many battles are physical, but if we incorporate the strategic thinking of Light Yagami from Death Note, it could add a new dimension. For instance, a character could plan out their moves against villains not just based on their quirks but also on out - thinking them like Light did. This could lead to more cerebral battles in the My Hero Academia universe. Also, the idea of a hidden identity, which was crucial in Death Note, could be introduced. A hero could have a secret identity that they use to fight crime in a different way, similar to how Light hid his identity as Kira.
Maybe the sludge villain has a sidekick or an accomplice who is enraged by his death. This person decides to take revenge on the heroes, especially the ones directly involved in the sludge villain's demise. They start targeting the hero's friends and family, creating a more personal and dangerous threat for the heroes.
One common plot is Kirby getting inserted into the My Hero Academia universe as a new kind of hero or villain. For example, Kirby might have his own unique quirk that combines his classic abilities from his own game with something more in line with the MHA world.
First, familiarize yourself with both universes thoroughly. Know the characters, their powers, and the rules of each world. For example, in Death Note, the rules about how the Death Note works are crucial. In My Hero Academia, it's about the Quirks. Then, come up with an interesting concept that combines the two. It could be something like a character from My Hero Academia getting a Death Note and how that changes their view of heroism.
One popular trope is the 'Quirkless Hero' where a character without a quirk manages to become a hero through sheer determination and intelligence. Another is 'Villain Redemption', where a villain decides to change their ways. 'Time Travel' is also quite common, with characters going back in time to fix things in the My Hero Academia universe.
One interesting plot could be the students pranking All Might by changing his costume into a ridiculous version. Maybe they use some quirk - related gadgets to make it look like his costume has turned into a giant plushie version of himself. Another plot might involve Deku being the target of a prank where his classmates make him believe he has lost his quirk for a day, which leads to some comical and self - reflective moments for him.
One interesting plotline could be a hero sacrificing themselves in a major battle against a powerful villain. This would have a huge impact on the other characters, like how Midoriya might be inspired to become even stronger in memory of the fallen hero.
One popular plotline is a battle between different heroes from My Hero Academia in a Death Battle - style fight. For example, Deku vs. Bakugo in a more extreme and rule - bound combat situation than in the original series.
One popular trope is the 'Quirkless Hero' where a character without a quirk manages to become a hero in some way. It's often used to show the power of determination and creativity. Another is 'Villain Redemption', where a villain character from the series gets a chance to turn good and change their ways.
