Out of all the episodes I've seen in the Nickelodeon ghost-hunting classic Danny Phantom, "The Ultimate Enemy" of season 2 might just be my all-time favorite episode of the show and one of the greatest episodes of any Nick series I've ever seen, along with the episode's main villain, the ghost boy's evil alternative future self, Dark Danny (voiced by Eric Roberts) became one of my personal favorite villains of any source of media!
