History NightmareFuel / DannyPhantom

** The Ghost King obviously never took Danny seriously. Let that sink in. Even [BadFuture Future Danny] took his past self serious when push came to shove, but even when faced with being imprisoned again, The Ghost King still saw Danny as a non-threat, knowing Danny was weakened by their fight.

* "WesternAnimation/TheUltimateEnemy" has the creation of [[FutureMeScaresMe Dark Danny]], pictured on the right [[spoiler:just before he murders his human self.]]
** It's not the scene that's freaky (though it has its {{Squick}} moments), but the part with [[spoiler:Dark Danny before he kills his human half]] gives off a face past the disturbance scale. Oh, if looks could kill...

** And just before that, Danny's evil half [[spoiler: claws Vlad's ghost form right out of him and then fuses with it.]] Dark Danny did some pretty disturbing stuff to his enemies.

** Just the fact that the writers went out of their way to make Dark Danny the evilest villain in the entire series. How evil is he? The whole reason he came into being was because of [[spoiler:his family and loved ones dying accidentally thanks to a mistake on his past self's part. But when he goes back in time and sees them all alive and well again for the first time in over a decade, he immediately starts plotting to kill them all '''on purpose''' this time around just to preserve his own existence.]] What the heck, Butch?!

** To be fair, his first appearance in "Control Freaks" had a scene where he has a [[BrainwashedAndCrazy]] Danny [[RedEyesTakeWarning with red eyes]] chase Sam onto a tightrope with a scythe, dressed up like the Grim Reaper. Danny's smile when he tries to kill Sam really doesn't help . . .

—> '''Clockwork:''' How about '''''two thousand'''''?

** It’s extremely brief, but when told to name a second evil thing Danny has done, Clockwork shows the future, then concluding with a question that emphasizes his point:

* Vlad's motivation for becoming a villain ({{murder the Hypotenuse}} protagonist's father so he can marry Maddie, his longtime crush, and gain custody of her children) is very, very, disturbing.

* And then there's ''Identity Crisis'', the episode where Technus is accidentally released from the "Level 0" glitch. Danny attempts [MesACrowd Form Duplication]] to fight him, resulting in nothing short of unadulterated BodyHorror (least of which being mouths for eyes and eyeballs on ends of tongues).

** Dark Danny's creation. Vlad did not expect for Danny Phantom to react, especially not to rip the ghost half (though given what he said about ripping out emotions, one could be said that all the emotional turmoil was left in Phantom). Then DP overshadows Plasmius and ends up absorbing him. Danny's utter ''scream'' of anguish pretty much makes it less of FaceHeelTurn and more of a ''FaceMonsterTurn'',

-->'''Dark Danny''' [[ThatManIsDead Well, I was, but I grew out of it.]]

** "...And then ''you'' will be '''''obsolete.'''''" That episode scared the ''crap'' out of me as a child.

* Let's talk about the Ghost King: he's said to be so powerful that the only way he was stopped was when a group of ghosts banded together, and even then they just knocked him out long enough to put him in a sarcophagus that kept him from waking up. It's also implied that when Danny was fighting him, the Ghost King was merely ''toying'' with him. Then there's Ember's line.

** It gets ''worse''; [[WordOfGod according to Butch Hartman]], Danny was the lucky one. Had it been Sam or Tucker in the portal when the accident happened, it would've '''''killed''''' them.

** Dark Danny turning around ''head first'' [[TheExorcist Exorcist-style,]] accompanied by a horrible cracking noise as his neck does things it clearly was not meant to do.

**Taken up a notch by that fact that is was his parents' invention that gave him his powers.

** It gets ''worse''; [[WordOfGod according to Butch Hartman]], Danny was just lucky. Had it been Sam or Tucker in the portal when the accident happened, it would've '''''killed''''' them.

* Also, think about how Danny got his powers. He is LITERALLY half-dead. That in its self is nightmare fuel.
