Fics like A Boys Second Chance

Izuku is in the middle of a fight against Shigaraki Tomura, trying to save the boy named Tenko deeply hidden within Shigaraki Tomura's mind. In a bid to save the child deep within, he is ultimately killed for his trouble inside the mindscape instead of Tenko at All for One's hand. Due to his vestige being killed in the Vestige world, All for One takes control over Izuku's body. Leaving Shigaraki Tomura to fight his mentor all on his own without Izuku being present, and even though Izuku's vestige is no longer present the boy's body makes it impossible for All for One to survive a fight against his successor.
