I think Icarus is the central figure in this fanfiction. But characters like Midoriya Izuku would also be important. Izuku's journey as a hero - in - training could be intertwined with Icarus'. Maybe they become friends or rivals. And villains from My Hero Academia, such as Tomura Shigaraki, could also be main characters. His evil plans might be affected by or target Icarus, adding more drama to the story.
In 'Icarus My Hero Academia fanfiction', surely Icarus is a main character. He might be the new element that shakes up the status quo in the My Hero Academia world. Alongside him, Ochaco Uraraka could be a main character too. Her friendly and positive personality could contrast with Icarus in an interesting way. And Katsuki Bakugo, with his explosive temper and strong quirk, would likely be involved as well. His interactions with Icarus could range from confrontations to begrudging respect.
