Danny Phantom is about a boy who becomes a half - ghost and has to navigate a world of ghosts and other strange phenomena. This is somewhat similar to Ghost Rider's journey with his otherworldly powers. But Danny Phantom is an independent creation with its own lore. It has its own backstory for Danny's transformation, his relationships with other characters like his friends and family, and different antagonists.
