Captain Hero[1] is a series of comics that dates back to at least from when All For One and his younger brother Yoichi Shigaraki were children.
Overview#
Captain Hero is a series of comics that tells the adventures of the titular protagonist against the Demon Lord. Either from the beginning of the story or at some point during it the main villain rules the world, forcing each and every person to pay tribute to him. However, Captain Hero struggled past the pain and in the end, he managed to defeat his nemesis and save everyone.
As children, All For One and his brother Yoichi enjoyed reading the comics together. Yoichi was a fan of Captain Hero while All For One was a fan of Captain Hero's nemesis, the Demon Lord. While his younger brother read the entire comic series, which ends with the villain's defeat at the hands of the hero, All For One read only to Volume 3 of the series, but stopped because he didn't like the cliched ending between "Hero" and "Villain".
The comic had a strong influence on the ideology of the two brothers. All For One dreamed of being a Demon Lord and creating a world just like the comics. While Yoichi fought for justice just like Captain Hero, trying to stop his older brother.[2] All For One would later express that he was infatuated by the idea of a person hated by every single person without exception. He believed, in accordance with his theory that negative experiences create the memories that last the longest, that such a person would hold the gaze of the entire world forever.[3][4]
The comic also had what All For One considered "jobber characters" who only existed to show off the Demon Lord's power.[5]
