Who would be the strongest if the characters from My Hero Academia and Demon Slayer met in fanfiction?

Tanjiro and Deku would be a very interesting pairing. Tanjiro has his strong sense of justice and his skills as a Demon Slayer, while Deku is determined to become the greatest hero. They could learn a lot from each other, like Tanjiro teaching Deku about perseverance in the face of great odds, and Deku showing Tanjiro how to better analyze an opponent's abilities.

It could be All Might. His One For All quirk gives him superhuman strength, speed, and durability. In the Demon Slayer world, he would be able to use these powers to take on even the strongest demons with ease. His experience as a hero would also give him an edge in strategizing against the demons.

I really like 'Quirked Slayers'. In this fanfiction, the author does an amazing job of integrating the quirk system into the Demon Slayer world. It's full of action - packed scenes where the heroes use their quirks to battle demons. It also has some great character development, especially for the characters that are a fusion of the two franchises.

In a fanfiction like this, there could be some interesting alliances. Eren from Attack on Titan, with his Titan - shifting ability, could team up with Deku. Deku could learn a lot from Eren's willpower and determination. Also, the quirks in My Hero Academia might be used to develop new strategies against the Titans. Like Todoroki could freeze the Titans' legs to stop them from moving.

The popularity of My Hero Academia Demon Slayer fanfiction lies in the combination of two very popular anime. Fans love to see how the unique elements of each can be mashed together. For example, the cool quirks from My Hero Academia and the intense demon - slaying action from Demon Slayer.

In some fanfiction, the characters might swap worlds. Tanjiro could end up in the world of My Hero Academia and try to understand the concept of Quirks while also showing off his sword skills. Maybe he'd even team up with Uraraka to take on villains. It would be really cool to see how they interact and learn from each other.

Midoriya Izuku is often a popular choice. Writers might explore how his heroic nature could be affected or enhanced by demonic elements. He could gain new powers or face new internal struggles.

One possible plot could be that the heroes from My Hero Academia are transported to the Demon Slayer universe. They team up with the Demon Slayers to fight a new breed of demons that have quirks. Midoriya could learn some sword - fighting skills from Tanjiro and in return, Tanjiro could gain some knowledge about using quirks in combat.

The Doom Slayer could be a mysterious figure in the My Hero Academia fanfiction world. He might be from a parallel dimension where his fight against demons is similar to the heroes' fight against villains. He could team up with the likes of All Might or Deku, teaching them about his unwavering determination. His presence would add a new level of intensity to the battles, as he doesn't hold back and is used to facing much more terrifying foes than the average villain in My Hero Academia.

It's hard to determine a single strongest character as it depends on various factors. Deku has great potential with One For All and Shigaraki has become a major threat with his evolving powers.
