Maybe they could combine Naruto's Rasengan with Bakugo's explosive power. Picture Naruto forming a Rasengan in his hand and Bakugo adding his explosive energy to it, creating an even more destructive and concentrated attack. This would be a really cool combination in a fanfic.
Millions and AFO were both important characters in My Hero Academy. They both had great strength and abilities. However, who was stronger depended on character settings and battle strategy.
Million Passers was one of the strongest heroes in My Hero Academy. He had invincible walls and unparalleled strength. His ability can resist all attacks and can reflect enemy attacks through walls. In battle, he usually adopted a static defense strategy to defend against the enemy's attacks by holding his position. Thus, the static defense of a million was very strong.
AFO was another very powerful character in My Hero Academy. He had the ability to fly and teleport. His ability allowed him to teleport anywhere and attack the enemy's weakness. In battle, he usually used dynamic attack strategies to defeat the enemy by moving quickly and attacking. Therefore, AFO was very powerful in terms of dynamic attacks.
Both Million Passers and AFO were very powerful characters. The stronger one was, the more determined the character's combat strategy and settings. Under certain circumstances, the Million Passers may adopt a more static defensive strategy, while under certain circumstances, AFO may adopt a more dynamic offensive strategy.
In most of such fanfictions, they might create evidence like hidden past connections. For example, AFO could be secretly involved in Izuku Midoriya's (Deku) family history. Maybe he had a relationship with Deku's mother long ago, which led to Deku's birth. But it's all fictional speculation within the fanfiction world.
One common plot twist is that Deku discovers the truth about his father in a moment of great crisis. For example, when he's facing off against AFO in a big battle, AFO reveals the truth to him, which completely shakes Deku's world view.
One possible analysis could be that their relationship in fanfic often showcases a strong bond of friendship. Bakugo's explosive personality and Kirishima's more stable and friendly nature create an interesting dynamic. Fanfic writers may explore how they support each other during battles or in their daily lives at school. For example, Kirishima might be the one to calm Bakugo down when he gets too riled up, and Bakugo could inspire Kirishima to be more confident in his abilities.
Bakugo is known to curse in the manga. This is used to emphasize his strong emotions and aggressive nature. However, the frequency and severity of the cursing might vary depending on the context of the scene.
