* In ''FanFic/ProjectTatterdemalion'', a quirk of [[GeneticEngineeringIsTheNewNuke genetically engineered biology]] means that people with PsychicPowers- shinigami and Quincies- really do need caffeine as a basic nutrient, especially when they use their powers a lot. Shinigami in particular also like it because it makes their hearts beat faster- the process that makes them shinigami slows their heartbeats way down, and caffeine brings it back to normal.
** A CrowningMomentOfAwesome from [[TheMedic Isane]] is driven by her need to get coffee - in her ''first appearance'' no less! She just woke up as a Shinigami, isn't very coherent and just wants coffee. A Hollow gets in her way. [[CurbStompBattle You can guess what happens next...]]

[[folder: ''Manga/Death Note'' ]]

* In the [[AlternateUniverseFic AU]] ''Fanfic/ThoseWhoStandForNothingFallForAnything'' Light and L stop for coffee in almost every chapter. [[BadBoss Light tends to sack people]] [[BerserkButton when he's deprived of his coffee.]] Also coffee is apparently so important to L that when they run out he rushes out to get more--[[AloneWithThePsycho leaving Light alone in the house with B.]]
* Light is a caffeine junkie again in ''[[http://archiveofourown.org/works/616971/chapters/1112940 To Feel Alive]]'' until Ryuk points out that it could have a negative effect on his lifespan.

[[folder: ''Western Animation/My Little Pony Friendship Is Magic'' ]]

* A cultural trait of the reindeer in ''FanFic/UnderTheNorthernLights''. It is also KlatchianCoffee, at least according to Spike. This is of course because their real life [[FantasyCounterpartCulture counterparts]], the Scandinavians, are heavy coffee drinkers.
* There's also a fic called "Pinkie Pie Discovers Coffee". HilarityEnsues when the already hyperactive and batshit crazy party pony does just that.


[[folder: ''Manga/Naruto'' ]]

* In the cracky fanfic ''Reload'', a GroundhogDayLoop type fic that long ago reached the lets-goof-off stage, we have Sasuke (who is currently female, long story) get up and reach for the nearest cup of coffee. Naruto comments that it was boiling moments ago.


[[folder: ''Anime/Pokemon'' ]]

* In the ''Sword and Shield'' Verse, a crime-based ''Anime/{{Pokemon}}'' fanfic, we have [[ActionGirl Brenda]] [[SirSwearsALot Johnson]], our main OC character who's partnered with [[OlympusMons Mewtwo]] aka [[DarkAndTroubledPast Vahan]] [[PsychicPowers Smith]]. Just Brenda, who prefers her coffee "liquid, preferably alive". On the other hand, Mewtwo has stoutly refused to resort to coffee. Brenda considers that a sign of insanity.

* {{Fanon}} likes to ascribe this trait to Nabiki in ''Manga/RanmaOneHalf''.


[[folder: ''Tabletop Game/Warhammer'' ]]

* ''FanFic/ToyHammer'': Commissar Tomas Sturm takes a liking to Terran "recaff" (a.k.a. coffee).
* Commissar Steve's entire motivation in ''Machinima/ADayInTheLifeOFACommissar'' is getting a cup of coffee. Justified, since his room-mate has night terrors and the beds are uncomfortable, so he barely gets any sleep. He goes completely berserk when he finds out Nathan Johnson, [[spoiler: the Force Commander of the local chapter of the Blood Ravens]], bought all the coffee on the planet. This escalates from teaming up with his SitcomArchNemesis, to challenging Johnson and his two friends ( [[spoiler: The Librarian and Chaplain]]) to a cage match, to demanding the use of a [[TankGoodness Baneblade]] Super-Heavy Tank.
