* UnevenHybrid: According to Butch Hartman even 3/4 Human, 1/4 Ghost hybrids have a ghost form and powers.

* EvenEvilHasStandards: All of Danny's ghost enemies hold an annual truce with any and all other ghosts (including half-ghosts like Danny) so that they can celebrate Christmas. When they discover the Ghost Writer broke the truce, they are ''not'' happy, [[EnemyMine teaming up with Danny to stop him]], and save Christmas.

* NuclearMutant: Half-ghosts are the result of the exposure to high levels of ghost energy.

* NotAlwaysEvil: ghosts are portrayed as {{always chaotic evil}} until the episode "Bitter Reunions" wherein [[spoiler: The Ghost of the Dairy King]] frees Danny Fenton and tells him “Not all ghosts are evil, you know, some just like to be left alone”.

* CallASmeerpARabbit: Zig-zagged. Many ghosts are clearly hinted or explicitly shown in-series to have been living humans (or animals), [[note]]Dorathea, Sidney Poindexter, Desiree, the Dairy King, Vlad's ghost mutant animals, and Hotep-Ra all have explicit backstories as humans or are otherwise shown to have been alive before. For the Lunch Lady, Cujo, and Ember, it's heavily implied (the latter also had a backstory given by the creators).[[/note]] and Maddie defines a ghost as an "odd manifestation of ectoplasmic energy and post-human consciousness". However, Butch Hartman insists that they're not the disembodied spirits of dead people, but "monsters/creatures" who have ghost-''like'' powers, contradicting canonical evidence. Some actually do behave more or less like stereotypical ghosts with GhostlyGoals and UnfinishedBusiness, especially early in the series, but in later episodes (especially in Season 3), the newly introduced ghosts started to look and act more and more like humanoid monsters instead, who are "ghosts" in name only aside from the ability to become invisible and intangible. In general, three types of ghosts can be identified: spirits of the dead (Ember, Desiree, etc.), ghosts that are personification of concepts (Nocturn, Clockwork, etc.), and naturally existing ectoplasmic creatures (the Ectopuses, Wulf, etc.).

* DoingInTheWizard: WordOfGod has {{retcon}}ned all ghosts as not the spirits of dead people, but actually otherworldly aliens made of ectoplasm, with the more humanoid ghosts simply making up human backstories.[[note]]This was very retroactive, as while this works with the more inhuman ghosts like Undergrowth, Vortex, and Nocturn. There is historical proof and in-universe confirmation that Desiree, Poindexter, The Dairy King and Hotep Ra at least were human in the past. Ember was also established by a director on the show as being the spirit of a dead teenager.[[/note]]

* ILoveNuclearPower: Half-ghosts are the result of the exposure to high levels of ghost energy.

* AlienBlood: Apparently, ghosts (and half ghosts in their ghost forms) bleed glowing green ectoplasm, as shown in "Fright Knight" when [[http://dannyphantom.wikia.com/wiki/File:S01e13_ectoplasm_from_cut.png Danny gets a cut by a blade]].

* DemonicPossession: Ghosts can take over the body of a living person and operate it like a puppet. This is called "overshadowing" in the show.

* GhostlyGoals: Which (if any) ghosts have "unfinished business" and will pass on after completing it is up for debate, considering the show never addressed afterlife beyond the Ghost Zone (though WordOfGod later revealed that the Heaven and Hell parts of the afterlife are the Elsewhereness and the Unworld respectively); however, almost every ghost Danny fights is the "attack the living" type.

* YouGottaHaveBlueHair: As with AmazingTechnicolorPopulation, this seems to be a thing for Ghosts.
