Intro. Danny and his friends are 18 now and going through their senior year of high school. Things seem to have calmed down with the ghosts. Their spectral forms appear around town less often. Most of them have developed a sense of respect for the town's hero, Danny Phantom. But others seem fearful of a new presence. Something dark and dangerous. Danny noticed the odd fearful behavior. However, all he could gather was that it wasn't another powerful ghost, or a ghost hunter. But something else entirely. And things became more serious when ghosts started popping up torn and shredded to pieces. Of course they all recover eventually once they regenerate their ectoplasm. But what could rip apart a ghost? Meanwhile, Amity Park gains a new resident. It's not often for people to move into the haunted town. So people were surprised by the new, unexpected stranger. Who coincidentally made their appearance not long after this unfamiliar supernatural creature started stalking the streets of Amity Park.
