* In Isaac Asimov's ''Literature/TheCavesOfSteel'', R. Daneel Olivaw is a human-shaped android who can "consume" food and drink to imitate a human. He actually stores the food in a bag within his stomach which he must empty or else it starts to spoil. He even offers the food from the bag to Lije Bailey, explaining that it's untouched and fit for consumption. Although Lije is a bit troubled at the thought of food going to waste, he refuses the offer.

-->"Old Overcoat. The genuine stuff. Two glasses and you rise up on a pillar of flame."
* In ''The Positronic Man'', co-written by Isaac Asimov and Robert Silverberg (and based on Asimov's short story ''Bicentennial Man''), a robot eventually upgrades himself with a device that converts food to energy.
* In Asimov's short story "Evidence" (the penultimate story in ''Literature/IRobot''), a man is suspected of being a robot because he was never seen to eat. The man states he doesn't like eating in public, but does eat an apple to demonstrate. Susan Calvin states it proves nothing, since such a perfect robot would be built with the ability to eat if needed. For some reason, the story ignores the point that the robot might actually require food - the design in question is {{Franchise/Terminator}}like, with flesh upon an artificial skeleton.
* In Alastair Reynold's ''Literature/TerminalWorld'' there exists "Carnivorgs" machines that use decaying neural tissue instead of circuits. To replenish their rotting parts, they eat brains.

* Cyborg from ''WesternAnimation/TeenTitans'' is a BigEater. Justifiable, as he's not entirely machine.

* ''Animation/{{Mechamato}}'': [=MechaBot=] can eat human food and loves curry puffs.

* In VideoGame/PlantsVsZombies2ItsAboutTime, several of the mechanical zombies, namely Zombie Bull, Rodeo Legend Zombie, Robo-Cone Zombie, Disco-Tron 3000, and Shield Zombie are all shown to be capable of eating your plants, as well as being vulnerable to the hypnotising effect of Hypno-Shroom and the poison of Shadow Shroom. In addition, in the Chinese version of the game at one point, Disco-Tron 3000 was vulnerable to the effect of Chili Bean.

* ''Anime/DragonBallZ'': Cell is an super android who has to feed to survive, except that his favorite meal is humans, who he absorbs by almost literally sucking up their bodies as he would suck liquid through a straw.

* Used as a heartwarming moment in an episode of Anime/SpaceDandy. It opens with the narrator explaining what circumstances would lead [[TheSmartGuy QT]] to drink a cup of coffee. He spends the episode seeking the affection of a coffee machine he [[LoveAtFirstSight fell in]] [[WhatIsThisThingYouCallLove love with]], [[spoiler: with tragic results]]. [[SubvertedTrope Subverted]] in that drinking it only blows out some of his fuses, but he just wanted to do it as a symbol of respect.

* Both Androids and Sentient Robotic Organisms (otherwise known as [=SROs=]) are playable races in {{TabletopGame/Starfinder}}, and both are capable of eating and drinking (though SROs don't have to).

* In ''VideoGame/HorizonZeroDawn'', the machines created by [[spoiler:[[FriendToAllLivingThings GAIA]]]] consume grass and other organic materials in order to fuel their [[MookMaker Cauldrons]] and themselves. PlayedForDrama, as [[spoiler: in the past, the [[StarfishRobots machines]] created by [[MegaCorp Faro industries]] nearly a millennium ago quite [[ApocalypseHow literally ate everything to extinction, right down to the microscopic level]] and turned Earth into a barren rock much like Mars.]]

* Difficulty to say in [[BigBad Zenith's]] case in ''Webcomic/CommanderKitty''. She's certainly seen [[http://www.commanderkitty.com/2010/09/12/table-for-blue/ at a restaurant]], claims to have [[http://www.commanderkitty.com/2010/12/12/nothing-to-see-here/ no room for desert]], and her "perfectly reasonable demands" for a travel service includes [[http://www.commanderkitty.com/2011/01/02/out-of-his-shell-and-off-his-rocker/ cashews]] and [[http://www.commanderkitty.com/2011/01/19/a-perfect-plan/#comments un-shelled pistachios]]. On the other hand, she's never ''seen'' eating, and it wouldn't be the only time [[http://www.commanderkitty.com/2011/07/12/well-theres-yer-problem/ she was wrong about her own functionality]].

* Exploited in [[http://neilaglet.tumblr.com/post/166781937856/d3fic8r this comic]], where a scientist tells his eating robot to [[ToiletHumor poop on another scientist]] who thinks building an eating robots is ridiculous.

* ''WesternAnimation/InvaderZim'': GIR is an example of a robot that has no use for food but pigs out on it anyway to the point of [[https://www.youtube.com/watch?v=K-0oL_bhjpI removing useful system components to make more room for stored snacks]].

* In VideoGame/PlantsVsZombies2ItsAboutTime, several of the mechanical zombies, namely Zombie Bull, Rodeo Legend Zombie, Robo-Cone Zombie, Disco-Tron 3000, and Shield Zombie are all shown to be capable of eating your plants, as well as being vulnerable to the hypnotising effect of Hypno-Shroom and the poison of Shadow Shroom.

* Aaron Stack, a.k.a. "Machine Man" from ''ComicBook/{{Nextwave}}''. "My robot brain needs beer!" In ''ComicBook/MarvelZombies 3'', however, he stated "I have no stomach, but I must barf."

* In ''VideoGame/HorizonZeroDawn'', the machines created by [[spoiler:[[FriendToAllLivingThings GAIA]]]] consume grass and other organic materials in order to fuel their [[MookMaker Cauldrons]] and themselves. PlayedForDrama, as [[spoiler: in the past, the [[StarfishRobots machines]] created by [[MegaCorp Faro industries]] nearly a millennium ago quite [[ApocalypseHow literally ate everything to extinction, right down to the microscopic level]] and turned Earth into a barren rock much like Mars. The machines of today were designed by GAIA to restore and maintain the Earth's biosphere.]].

* In ''VideoGame/HorizonZeroDawn'', the machines created by [[spoiler:[[FriendToAllLivingThings GAIA]]]] consume grass and other organic materials in order to fuel their [[MookMaker Cauldrons]] and themselves. PlayedForDrama, as [[spoiler: in the past, the [[StarfishRobots machines]] created by [[MegaCorp Faro industries]] over four centuries ago quite [[ApocalypseHow literally ate everything to extinction, right down to the microscopic level]] and turned Earth into a barren rock much like Mars]].

* In Isaac Asimov's ''Literature/TheCavesOfSteel'', R. Daneel Olivaw is a human-shaped android who can "consume" food and drink to imitate a human. He actually stores the food in a bag within his stomach which he regularly empties. He even offers the food from the bag to his human friend, explaining that it's untouched and fit for consumption. The human obviously refuses.

* Subverted in the obscure B-movie sequel, ''Film/ClassOf1999TwoTheSubstitute.'' It is believed that the huge substitute teacher is an android and he's a BigEater, he even says "My body turns food into fuel quite quickly," but it turns out he's just a man who ''thinks'' he's an android.

* ''[[https://my.w.tt/6Vg6fGMEsT Final Stand of Death]]'' has Hawk drinking a [[SpotOfTea cup of tea]] despite being a sentient mecha. Then again, like the rest of Fusion Gundam, Hawk is British. Eariler, Spur tries her luck with from soda.

* In the MarvelUniverse, the original Human Torch (who, despite his name, was an android) used to eat and drink.

* In ''Fanfic/{{Origins}}'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, a proposed ship crewed by geth is designed to consume organic matter as fuel. [[spoiler:Specifically, dead Flood biomass which is burned down to carbon and subjected to fusion.]]

* ''WesternAnimation/FinalSpace'': {{Deconstructed}} by [[Characters/FinalSpaceTheTeamSquad KVN]]. He biologically can't eat but he still loves smashing cookies into his "mouth", essentially just wasting food.

* {{Downplayed|Trope}} in ''WesternAnimation/{{Robotboy}}''; he and Robotgirl are shown to be able to eat human food, but whenever they do it gums their gears together, which brings up the question of [[FridgeLogic why they have]] [[InventionalWisdom a sense of taste]] but no mechanical stomach for food to go.

* Subversion in ''WesternAnimation/MyLifeAsATeenageRobot'': Trying to fit in with her new human friends Jenny eats an ice cream cone (in one bite) but as soon as they look away she opens a door in her chest and throws the ice cream away. The only things she "eats" is various kinds of oil (including salad dressing oil).

* Octus from ''WesternAnimation/SymBionicTitan'' is seen eating icecream bars in one episode and also ate cookies when disguised as Lance and Ilana's father. Unlike most examples of this trope, he's also capable of tasting them, as most of his body is a shaped fluid that can analyze whatever is put in it.

* In ''Fanfic/TheAFRUniverse'' story "Agent Hanamura", [[VideoGame/Persona4 Yosuke]] is invited to a dinner interview with [[VideoGame/Persona3 Mitsuru]] and [[VideoGame/Persona4Arena Labrys]]. Yosuke comments on [[RediculouslyHumanRobot Labrys]] eating. She claims that she's powering herself with an experimental nuclear reactor that burns the food as fuel, before admitting it was a joke. She actually has a refrigerated storage container in her body so she can pretend to eat while undercover as a human and then dump the waste later. She plans to give the steak she just "ate" to [[TeamPet Koromaru]] later.

* Subverted in the obscure B-movie sequel, ''Film/ClassOf19992TheSubstitute.'' It is believed that the huge substitute teacher is an android and he's a BigEater, he even says "My body turns food into fuel quite quickly," but it turns out he's just a man who ''thinks'' he's an android.

* Subverted in the obscure B-movie sequel, ''Class of 1999 2: The Substitute.'' It is believed that the huge substitute teacher is an android and he's a BigEater, he even says "My body turns food into fuel quite quickly," but it turns out he's just a man who ''thinks'' he's an android.

* ''WesternAnimation/{{Futurama}}'': Bender (like all Earth-made robots) is designed to run off booze. They act drunk when they ''don't'' have alcohol; indeed, in one episode, Bender is arrested for driving with less than the ''minimum'' alcohol level required for a robot to operate a vehicle. Robots also consume prepared fuel as "robot food." While they can and do eat human food, it presumably doesn't do anything for them (and Bender, at least, has no sense of taste, [[LethalChef despite his passion for cooking]]).

* Franchise/{{Transformers}} in ''WesternAnimation/BeastWars'', while in [[AnimalMecha beast mode]], are able to eat things that would be edible to terrestrial animals, rather than typical Transformer "food" like oil. Perhaps most notoriously, Rhinox eats some wild bean vines and [[{{Fartillery}} develops literally explosive flatulence]]. Tarantulas is known to prey on local animals, and once even attempted to eat ''[[SapientEatSapient Cheetor]]''.
* Subverted by BMO in ''WesternAnimation/AdventureTime'', who keeps ''trying'' to eat, but the food either just get mushed into their [[TVHeadRobot screen face]] or is put inside and has to be cleaned out. Likewise, the [=SMOs=] security guards in "Be More" all take breaks to smear coffee and donuts all over their faces.
* In ''WesternAnimation/MrHublot'', a {{Steampunk}} cartoon where every living thing is actually mechanical, they eat not food, but some sort of congealed oil concoction. The dog can be seen to have steel nuts and bolts floating in it.
* In ''WesternAnimation/TheTransformers'', the [[ExtremeOmnivore Insecticons]] are shown to have been capable of eating anything, including trees, grain, and buildings.
* {{Downplayed|Trope}} in ''WesternAnimation/{{Robotboy}}''; he and Robotgirl are shown to be able to eat human food, but whenever they do it gums their gears together, which brings up the question of [[FridgeLogic why they have]] [[InventionalWisdom a sense of taste]] but no mechanical stomach for food to go.
