Fics like Bloodlines of the Shadows

After the traumatic events of the Triwizard Tournament and Cedric’s death, Harry returns to Privet Drive, only to be brutally attacked by the Dursleys. Left nearly dead, he’s rushed to a Muggle hospital where his blood is tested — and flagged for a rare match. Across the ocean, Bruce Wayne receives the alert: a potential relative, a boy with the same blood markers. Intrigued and suspicious, he sends Alfred to investigate. As secrets unfold and the wizarding and Gotham worlds collide, Harry discovers a truth that may change everything — that he is the last surviving descendant of the Wayne family, and Bruce may be more than just a billionaire in a mask.
