I'm not sure specifically as there could be many different takes in such a fanfiction. It might involve Naruto somehow taking on the role or characteristics of the Radio Demon from some other context. Maybe it's about Naruto using radio - like powers in a new and strange world.
Maybe the Radio Demon enters the Harry Potter universe first. It could be attracted by the powerful magic there. And then it somehow fuses with Harry Potter, giving him additional powers. Harry then has to deal with the reactions of his friends and the wizarding community while also trying to control these new powers and the influence of the Radio Demon within him. The plot could revolve around Harry's struggle to maintain his identity and use these powers for good in a world that is both familiar and now very different.
The first place to look for the 'naruto is the radio demon fanfiction' is on well - known fanfiction platforms. FanFiction.net has been around for a long time and has a large number of Naruto - related fanfictions. You can simply enter the title in the search box. AO3 is also a good option. It's known for its high - quality and unique fanfictions. Additionally, some Naruto fan groups on social media platforms might share links to such fanfictions if they are aware of them. But be cautious when clicking on links from unknown sources to avoid potential malware or inappropriate content.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
His friends could come to the rescue. Bakugo, for instance, might use his explosive power to break into Toga's hideout. He's always been competitive with Deku, but he also cares about him deeply.
In 'deku meets future deku fanfiction', perhaps the future Deku warns the present one about upcoming threats. He could tell him about villains he'll face in the future and how to defeat them. This would give the present Deku an edge in his battles and also in his growth as a hero.
Well, obviously Deku in two forms - the younger and the older version are the main characters. The younger Deku is the one who is still growing and learning, while the older Deku has more experience.
