History WesternAnimation / TheUltimateEnemy

* MisplacedRetribution:
** Summed up by Tucker when he and Sam figure out what causes the BadFuture.
-->'''Tucker''': Let me get this straight. [[spoiler:Danny gets caught cheating on a test, and ''we'' pay for it with ''our'' lives?]] How is ''that'' fair?
** [[spoiler: The ghosts in the future takes their aggression out on past Danny despite him stating he never did the action his future self would. They don't care since they figure Danny will grow up into Dark Danny anyway and hold him accountable regardless.]]

* NearVillainVictory: [[spoiler: Though Danny wins the battle against his evil future self, Dark Danny still kept him distracted enough that the Nasty Sauce being heated reached a critical point and exploded as intended. It's only thanks to Clockwerk interfering and saving Danny's family and friends that prevents Dark Danny's victory.]]

* MakeMeWannaShout: The most prominent ghost power in this special is the Ghostly Wail, which first appeared [[spoiler:when Dark Danny knocked out the towers generating the ghost shield around Amity Park]], then [[spoiler:Danny himself got it when he was being attacked by future versions of his enemies]]. It came in quite handy [[spoiler: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]].

* HeroicRROD: At the absolute ''worst'' possible time, [[spoiler:after defeating Dark Danny with the Ghostly Wail and trapping him in the Fenton Thermos, Danny rushes over to save the others from the Nasty Sauce... but he's too far away, he can't "Go Ghost", and the Nasty Sauce is ''seconds away from blowing'']].

-->'''[[spoiler:Dark Danny]]:''' What kind of parents are you, anyway? The world's leading ghost experts, and you can't figure out that your own son was half-ghost! ... Hello? Danny Fenton. Danny ''Phantom''. Ever notice the similarity? Jazz did.

''WesternAnimation/DannyPhantom'''s second MadeForTVMovie.

* IdiotBall: [[spoiler:Dark Danny knocked Jazz out and dragged her away somewhere before she could use the Fenton Peeler to expose him during the C.A.T. While it's understandable that he left her alive for the moment, he neglected to break the Peeler when he had the chance, which ended up causing a major shake up in his plan]]. [[spoiler: Although the present Danny suggests that Dark Danny had forgotten much of their parents' inventions.]]

* IdiotBall: [[spoiler:Dark Danny knocked Jazz out and dragged her away somewhere before she could use the Fenton Peeler to expose him during the C.A.T. While it's understandable that he left her alive for the moment, he neglected to break the Peeler when he had the chance, which ended up causing a major shake up in his plan]].

* BadFuture: [[spoiler:And all just because of cheating on one little test.]]

* DeusExMachina: Although Clockwork only intervenes in the climax because he concludes Danny [[EarnYourHappyEnding earned it]], the fact still remains that the TimeMaster stepped in and saved everyone when there was no way the hero could have done it on his own; [[spoiler:Danny didn't reach his friends and family before the explosion killed [[TimeTraveltenseTrouble (or would have killed...?)]] them]]. Even the Observants [[LampshadeHanging seem to see it this way]] when they tell him, "[[{{Irony}} You cheated!]]"

* TorsoWithAView: When Jazz tries to land a blow against [[Dark Danny]], he merely creates a hole in his chest to let the attack go through him unharmed before it reseals without problem.

* HandcuffedBriefcase: In his paranoia, Lancer places the C.A.T answer key in a briefcase that he cuffs to his wrist. Unfortunately, it doesn't work when Danny accidentally phases through the case and gets the answers stuck to his back.

* AnArmAndALeg: In the BadFuture, Damon Grey and the Box Ghost are missing an arm.

%%* EyepatchAfterTimeSkip: The Box Ghost.

* LaserGuidedAmnesia: [[spoiler:It's hinted that a side-effect of Dark Danny's creation is that he lost a majority of Danny's memories, such as where Vlad's ghost portal is when it's obviously in Wisconsin, and Danny commenting that he didn't recognize the ghost weapons he was using]].
** Then again, Vlad is implied to have moved his base to a new location after [[spoiler:losing his mansion (again) in the incident that created Dark Danny]].

* MisplacedRetribution: Summed up by Tucker when he and Sam figure out what causes the BadFuture.

* NiceJobBreakingItHero: Clockwork sends Box Lunch back in time to eliminate Danny [[spoiler:before he turns evil]]. Danny's fight with Box Lunch sets the events that lead to [[spoiler:Danny losing everything that mattered to him leading to the creation of [[EvilTwin Dark Danny]]]] (Danny acquiring the test answers and the explosion that would take the lives of his family and friends).

** [[spoiler:Danny's human half in his BadFuture]]. 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. [[FridgeHorror What do you think happened to all of the people]]?

* UnwittingInstigatorOfDoom: Had Mr. Lancer not made it seem like the test was such a big deal, there's good chance the events of the episode wouldn't have happened.

* LiteralSplitPersonality: How [[spoiler:Dark Danny was created: Danny has Vlad use a device to separate his ghost half from his human half, except Ghost Danny becomes malicious for some reason. Ghost Danny then takes the device and uses it on Vlad to separate ''his'' ghost and human halves, and overshadows Ghost Vlad for some reason, resulting in the two of them fusing together into Dark Danny. Then he kills Human Danny, [[FamilyUnfriendlyDeath in a manner so brutal]] that Human Vlad refuses to describe it]].

* ChekhovsGun: The Boo-merang that is keyed into Danny's ecto signature [[spoiler:both helps Jazz realize Dark Danny is impersonating Danny and to find Danny in the future]]. It's just too bad it wasn't used yet again so that it could be a literal ChekhovsBoomerang.

** Then again, Vlad is implied to have moved his base to a new location after losing his mansion (again) in the incident that created Dark Danny.

* ChekhovsGun: The Boo-merang that is keyed into Danny's ecto signature [[spoiler:both helps Jazz realize Dark Danny is impersonating Danny and to find Danny in the future]].

* KnightOfCerebus: [[spoiler:Dark Danny. So, so much.]] Unlike any other villain before or after him, even Vlad Plasmius, there is nothing light-hearted about him and even his humerous moments only serve to emphasize how evil he is.

* LaserGuidedAmnesia: [[spoiler:It's hinted that a side-effect of Dark Danny's creation is that he lost a majority of Danny's memories, such as where Vlad's ghost portal is when it's obvious in Wisconsin, and Danny commenting that he didn't recognize the ghost weapons he was using]].

** [[spoiler:Though Vlad does mention that Danny was so [[DespairEventHorizon despondent from losing his family and friends]] that he asked Vlad to take the pain away, and Vlad implies that he might have taken the opportunity to remove Danny's goodness like he'd been trying to do all series, and/or Danny's desire not to feel had GoneHorriblyRight. Either way, Danny's ghost half's inability to feel just created a literal [[TheSociopath sociopath]] incapable of any positive emotion, including discretion, mercy, or remorse. Poor Danny [[BeCarefulWhatYouWishFor got exactly what he wanted]].]]

* LoveIsAWeakness: [[spoiler:Dark Danny]] certainly thinks so, and is determined to stamp out every ounce of love and kindness in himself and [[IHatePastMe his past self]].

* PowerNullifier: One of [=SkulkTech=]'s weapons is a device called the [[AddedAlliterativeAppeal Phantom Palm Pummeler]] which can short out ghost powers. [[spoiler:Dark Danny is too powerful for it to affect him]] but it can work on present-day Danny.

* TimeDissonance: Clockwork doesn't view time the linear way humans (and [[{{Seer}} the Observants]]) do.
