Izuku sings at the Sports Festival thanks to the Vestiges
Just a silly idea that popped into my head, feel free to write it yourself.
At the Sports Festival, Izuku is called up to speak to the crowd instead of Katsuki because Nedzu wanted the student with the highest Rescue Points total to speak. Seeing as Izuku is a nervous wreck, the Vestiges of One For All (in this story, they met Izuku much earlier) share confidence with him as he walks up to the mic and Yoichi has the brilliant idea to feed lines to Izuku about how every one of his fellow competitors dreams of being lauded by the public as a Hero before he starts singing Michael Bolton's rendition of "Go The Distance" from Disney's Hercules. The Vestiges accompany him by becoming a spectral orchestra surrounding him playing horns and strings as he belts out the song, and when it ends the entire crowd goes nuts.
That's it, that's all I really had.
