Big Eater/Fan Works

Thin Characters

 * John in With Strings Attached. 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.
 * Socrates from Calvin and Hobbes: The Series; at one point he builds and tries to eat an actual food pyramid.
 * In The Tainted Grimoire, many are they who are shocked at how much Cid and Ensei can eat.

Fat Characters
"Ron: Accio double-stuffed!"
 * In A Very Potter Musical, 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.


 * Wheatley becomes this after GLaDOS implants his brain into a human body in the Portal 2 fic Test of Humanity. He ends up eating everything in Chell's fridge after tasting food for the first time, and, later on, G La DOS tricks him into eating 30 cakes. By the end of the fic, he's grown noticeably fatter.
 * The 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 Calvin and Hobbes: The Series - the latter ate an entire turkey in a few bites.
