Devil Hulk

As a child, Brian and his sisters Susan and Elaine, along with their Mother were physically and emotionally abused by his Father, Bruce Banner I. Regarding his father as a monster and believing that he had inherited a "monster gene" from him, Brian promised himself that he would never have any children, for fear of bringing another Banner into the world. He severed contact with his sisters not wanting to relive bad memories from their childhood and wanted to escape his by running from it.
