Western Animation: The Ultimate Enemy

Danny Phantom's second Made-for-TV Movie. With an all-important test coming up that he hasn't had time to study for, Danny finds himself in a pickle until he accidentally obtains the test answers. As he decides to cheat on the test, a mysterious ghost named Clockwork attempts to eliminate him to prevent his decision from having catastrophic effects on the world.

The Movie shows examples of:

  • Alas, Poor Villain: Most of Danny's Rogues Gallery suffer horrible fates because of Dark Danny's actions. Vlad Masters himself becomes The Atoner after he realizes that he has created a monster.
  • An Arm and a Leg: In the Bad Future, Damon Grey and the Box Ghost are missing an arm.
  • Apocalypse How: Dark Danny single handedly brought about a Class 1 in the future. If it weren't for Danny, it probably would've been raised to a Class 3a.
  • Bad Future: And all just because of cheating on one little test.
  • Can't Get Away with Nuthin' : Danny cheats on a test, which causes the horrible deaths of his entire family, his best friends, and his teacher.
  • Darker and Edgier: Tied with Kindred Spirits as the darkest episode in the entire series. It's also a fan favorite.
  • Despair Event Horizon: In the Bad Future, it was clear that Danny went over this line following the loss of his family and friends, leading him to the operation that resulted in Dark Danny's creation.
  • Drama Bomb: Jawdropping. Not least for its awesomeness, abruptness, as well as its sudden venture into dark humour. Oh yes, and the brutal murders, so many brutal murders.
  • Even Evil Has Standards: Vlad Plasimus is horrified by what Dark Danny does to his human half.
  • Evil Cripple: Future Johnny 13 is confined to a wheelchair thanks to his injuries from Dark Danny.
  • Evil Future Me Scares Me: Along with everyone else.
  • Family-Unfriendly Death: Danny's human half in his Bad Future. So much so that Vlad refuses to divulge any of the details. Some things are best left unsaid.
    • The entire world outside of Amity Park has been destroyed. What do you think happened to all of the people?
  • For Want of a Nail: Danny cheating on a test sets off a long string of events that ultimately end with his family, friends, and teacher dead and his ghost half splitting off from him, becoming evil, and attempting to destroy everything. At the end, Danny knows this ahead of time and thus chooses to not cheat in order to avoid this string.
  • Future Badass: Plenty, from Valerie to Box Ghost.
  • Heel Realization: After being without ghost powers for ten years Bad Future Vlad realized what a fool he'd been, shunting his best friend away for marrying the woman he loved and resenting their happiness, leaving him to revel in his loneliness. You know it's genuine when he repaired the photo of him, Maddie, and Jack to include all of them, and outright admits that it's probably the only "good" that came out of the entire ordeal. Though he momentarily considered destroying Danny to change the future, he ultimately helped Danny return to his own time.
  • Heroic Vow: Danny promises his family and friends that he will not turn into Dark Danny. Dark Danny mocks him for it.
    Dark Danny: Oh, you are such a child! You promised?
  • Knight of Cerebus: Dark Danny. So, so much.
  • Make Me Wanna Shout: The most prominent ghost power in this special is the Ghostly Wail, which first appeared when Dark Danny knocked out the towers generating the ghost shield around Amity Park, then Danny himself got it when he was being attacked by future versions of his enemies. It came in quite handy during the climatic battle with Dark Danny, not to mention shocking him as Danny got it ten years earlier than him, proving the future could be changed.
  • Nice Job Breaking It, Hero: Clockwork sends Box Lunch back in time to eliminate Danny before he turns evil. Danny's fight with Box Lunch sets the events that lead to Danny turning evil (Danny acquiring the test answers and the explosion that would take the lives of his family and friends).
  • Not-So-Harmless Villain: Future Box Ghost is a lot more powerful and serious than he is in the past. Also, the fact that he's got a hook for a hand and is missing an eye is terrifying.
  • Painful Transformation: Dark Danny's creation.
  • Sealed Evil in a Can: Dark Danny was sealed away in a Fenton Thermos and left with Clockwork, though for how long is unknown.
  • Secret Test of Character: Clockwork's plan in general. He knows Danny's a good if not brash kid and doesn't deserve the dreary future set for him. So he allows Danny into said Bad Future to see if he can change things.
  • Self-Made Orphan: Dark Danny didn't just kill his parents, he killed his sister, his friends, and his teacher... just to secure his own future.
  • Stable Time Loop: Clockwork sends Box Lunch back in time to kill Danny before the Bad Future happens, which is a result of the Nasty Burger exploding and taking pretty much everyone Danny cares about with it. However, Danny and Box Lunch's fight is what leads to the Nasty Burger's later explosion (as well as Danny getting the test answers). Fortunately, this Stable Time Loop is broken thanks to Clockwork's intervention.
  • Serious Business: The CAT. If you fail this one test in your freshman year of high school you will be forever doomed to spend the rest of your life working a dead end job at the local fast food joint. On the other hand, if you score high on the test, as Jazz did, the most successful future possible is assured.
  • Shoo Out the Clowns: Or rather blow them up.
  • Time Travel
  • Vile Villain, Saccharine Show: Many of Danny's enemies have many Affably Evil moments and/or comedic.. Dark Danny is never Affably Evil and his atrocities are played dead serious...as his ghost status would indicate.
  • You Can't Fight Fate: This is Dark Danny's attitude throughout most of the film, believing that Danny's Bad Future is inevitable. However, Danny's will to Screw Destiny was so strong he gained the Ghostly Wail, Dark Danny's most powerful ability ten years early, shocking Dark Danny in more ways than one.
  • You Do NOT Want to Know: This is what Future Vlad said to Danny regarding the fate of Danny's human self in the future.
