Not no. Representing One of the most loved characters in the whole history and story of "My Hero Academia" is the man just above this. Believe me, if something happens to this towering figure, meanwhile the earth shakes Tokyo as anyone would feel ripples they've never known. In the realm of anime you could say it must be so. Besides, All Might's "Symbol of Peace" moniker may only have been brought about at the very end of his plus ultra career. The most robust Pro Hero, he gave his powers to Izuku Midoriya after their monumental battle with All For One and retired. Thereon in, he stayed a guiding force, a teacher and invaluable font of wisdom for young heroes even if not in person any longer. His continued existence is a source of hope and strength to many both inside and outside the anime. So even though his valorous fighting days are behind him now in a way like that because just shows who the man was was Almight he's still hoeing for the peace he once stood for. He's now gone from action to academics, with teaching and mentoring pushing bad guys out of his way. Even though his fighting legacy has perished, the hero lives on in his successor Izuku Midoriya. Every breath All Might takes, every last bit of strength he possesses is devoted to making Midoriya into an even greater hero than All Might ever was. Although you have a man today who comes and goes nowhere, I am but afraid that his spirit will continue in a very real and significant way, with all he has done through the ages to contribute toward peace, stability and progress.
