!!Thin Characters

* In the JackieChanAdventures fic ''Fanfic/QueenOfAllOni'', after Jade becomes a Shadowkhan girl once more, her appetite and metabolism greatly increased, to the point that, in one chapter, she is described as [[spoiler: eating a rib, [[ExtremeOmnivore BONE AND ALL]]]], and has eaten large amounts in several other chapters (to be fair, she did have a big appetite BEFORE the transformation, as Season 2 episode 9 shows).
* In the ''WesternAnimation/JackieChanAdventures'' and ''WesternAnimation/TeenTitans'' crossover fanfiction ''Fanfic/AShadowOfTheTitans'', by the same author as ''Fanfic/QueenOfAllOni'' above, Jade has had her appetite increase after being transported to the TT universe and becoming a Shadowkhan again, but this case there's more focus on the ExtremeOmnivore aspect, as Jade has taken to eating metal and wood, with Jinx repeatedly lampshading this, [[RunningGag asking Jade if she's part goat or something]].
* John in ''Fanfic/WithStringsAttached''. Eats at least three times what a normal person eats. He can ingest and draw nutrients from just about any organic substance. As a side effect, he's immune to poison and drugs, including alcohol.
** For some reason, [[Music/TheBeatles Beatles]] {{Fanon}} has decided that GeorgeHarrison is one of these. Could have something to do with his [[TrademarkFavoriteFood supposed love for jelly babies]] in RealLife, or his epic sandwich-munching on the train in ''AHardDaysNight''. Plus, there are a ''lot'' of photographs of him eating.
* Socrates from ''[[Fanfic/CalvinAndHobbesTheSeries Calvin and Hobbes: The Series]]''; at one point he builds and tries to eat ''an actual food pyramid.''
* In FanFic/TheTaintedGrimoire, many are they who are shocked at how much Cid and Ensei can eat.
* Agumon was always a big eater, but in [[http://www.fanfiction.net/s/7623289/1/ Transcendence: Digital Curse]] he consumes enormous amounts at some times. At one point he manages to eat a dozen or so containers of food, and he keeps eating an unspecified amount more. Justified in that case.
* Haruhi, Kuyou, and Tsuruya in ''FanFic/YouGotHaruhiRolled''. The latter is implied to be able to devour at least ten times her own body weight.
* [[NonActionSnarker Kit]] from the HungerGames fanfic ''Fanfic/SomeSemblanceOfMeaning'' is a MouthyKid in more ways than one. When asked what his favorite food is, he responds, "Everything!" And the narrative once described him as "eagerly attempting to gobble down half of the Capitol's food supply" at breakfast.
* Simba and Haiba in ''Fanfic/TheLionKingAdventures'' both love their food.
** Simba eats way too much food at King Hapana's pride in ''Desperate Measures'', developing a BalloonBelly in the process. [[spoiler: It turns out that King Hapana was deliberately fattening him up in order to slow him down so he couldn't escape.]]
** Haiba eats so much at Jowai Resort in ''Changes'' that he becomes morbidly obese. It also spawns his alter ego, Don Haiba.
** In both cases, the obesity wears away by the next story.
* Nabby of ''Fanfic/EmpathTheLuckiestSmurf'' is just the same size as any adult Smurf, but he's a big eater like his brother Greedy.
* Tails the fox takes this to RunningGag levels in the fanfic ''Fanfic/TailsOfTheOldRepublic'', a crossover/ FusionFic between ''Franchise/SonicTheHedgehog'' and the videogame ''Franchise/StarWars: VideoGame/KnightsOfTheOldRepublic''. Tails regularly stuffs himself to the brim whenever he can shovel food into his mouth. Carth Onasi lampshades this when he asks, "Were you ''chronically starved'' on your planet?!?" Justified somewhat in that Tails is an adolescent fox now with a HyperactiveMetabolism, and that [[spoiler:his cybernetic augmentations consume energy too, and will scavenge his tissues for resources if he doesn't eat.]]
* ''FanFic/TheTwilightChild'': Scootaloo manages to win an eating contest against already established BigEater Pinkie Pie, as well as Rainbow Dash and Trixie.
** Princess Celestia, as well. At Twilight Sparkle's birthday party a character notices her casually chowing on an extremely large wedge of cake, to the horror of the Canterlot ponies watching.

!!Fat Characters

* In ''AVeryPotterMusical'', Ron Weasley always has a snack, including but not limited to: a carton of Chinese food, a bag of Funions, Twizzlers handed to him by a member of the band, and a Hershey bar the size of his torso.
-->'''Ron:''' Accio double-stuffed!
* Wheatley becomes this after [=GLaDOS=] implants his brain into a human body in the ''VideoGame/{{Portal 2}}'' fic ''Fanfic/TestOfHumanity''. He ends up eating everything in Chell's fridge after tasting food for the first time, and, later on, GLaDOS tricks him into eating 30 cakes. By the end of the fic, [[AuthorAppeal he's grown noticeably fatter]].
** The [[http://www.fanfiction.net/s/7046503/1/Test_Of_Humanity_2 sequel]] has Chell's roomates being unable to make anything for dinner because Wheatley already ate nearly everything. And, Wheatley then admits he made a large order for Chinese takeout...most of it being for him to eat.
* Sheila Brainstorm and her mother from ''[[Fanfic/CalvinAndHobbesTheSeries Calvin and Hobbes: The Series]]'' - the latter ate ''an entire turkey'' in a few bites.
* Mike gets away with being called fat in ''FanFic/{{Pokeumans}}'' - as a Ditto he resembles a pink fleshy blob and turns into a Munchlax so he can eat more.
* Choji in the ''Manga/{{Naruto}}'' fanfic ''FanFic/KitsuneNoKenFistOfTheFox'', just like his canon counterpart. At one point, Sasuke actually takes advantage of this to convince him to fight Shikamaru during the qualifying round of his tournament--in addition to getting tickets for the upcoming ''[[ShowWithinAShow Shadow Fox]]'' comic-book movie, they're told that there'll also be a buffet line, as the screening they'll get to see is that which is usually reserved for movie critics. Choji immediately jumps on board.
* [[Franchise/DragonBall Yajirobe]]'s appetite is played up in ''WebVideo/DragonBallZAbridged'', most notably with an [=FAQ=] video where he apparently started eating Yamcha's body and Bulma correctly fearing he might eat Trunks out of spite and/or hunger.
