Many characters have Bizarre Taste in Food, but they still eat things recognizable as food. Many characters are Extreme Omnivore, but at least they eat physical objects. In fiction, almost anything can be food, an Abstract Eater eats things which aren't so much things but concepts. Individuals with these tastes will feed on anything from lost possibilities to sanity, love, or even coolness. Though they may also enjoy the material as a side dish, all of these foodies get some kind of benefit from the abstract dish of their choice. The process of eating something abstract could be portrayed in any number of ways, as it's up to the creators of the work to describe what it looks like to see something intangible be devoured. This can often be Horror Hunger, as it often leads to the Eater of the Abstract feeding of the actions or traits of folks like us, leading to humans in behaviour farms and/or a deficiency of the tasty concept in the world or its previous host. A common aspect of Eldritch Abominations, naturally. Emotion Eater and Spacetime Eater are subtropes where the abstract food is human emotion and the fabric of the universe, respectively. When prayer is eaten, this overlaps with Gods Need Prayer Badly.
ExamplesAnime and Manga

- In Majin Tantei Nougami Neuro, the plot is kicked off when the demon Neuro comes to Earth to feed off the complexity generated by riddles, puzzles, and mysteries.

Incidentally, this enables the host to instantly understand any form of communication whatsoever. It is said that the poor Babelfish has wreaked more havoc on sentient life in the universe than all armies that ever marched combined, due to obliterating all boundaries to understand one another.
- Diane Duane's Star Trek novels have the Iruhe, who eat the minds of sentient beings, leaving only breathing but mindless bodies. They appear briefly in The Romulan Way, where they devour the minds of two ships' worth of Romulans (who have just left Vulcan and were in the process of looking for a new homeworld, and were lured in by the Iruhe's illusions of a water-rich, habitable planet); the rest of the fleet barely escape. The Iruhe are also the villains of her TNG book Intellivore, where they have gained the ability to move their planet about to prey on planets rather than just starships.

- Red Dwarf has the emohawk, a domesticated breed of the Emotion Eater ploymorph that instead feeds on personality traits, during its episode it enjoys a meal of Rimmer's bitterness and Cat's cool. While this left the Cat in his bumbling and useless Duane Dibbley persona, it radically helped Rimmer, who became his heroic parallel universe persona Ace Rimmer. What a guy!
- Buffy the Vampire Slayer season five Big Bad Glory had to manage her hell god composure by eating human sanity. Leaving her victims gibbering wrecks.

- In "Amy's Choice", the psychic pollen that places the Doctor, Amy and Rory in a shared dream state fed off the darkness in its victim's minds, creating the image of the Dream Lord as a manifestation of the Doctor's own self-hatred.
Amy: But why didn't it feed on us, too?

- The planet-sized creature known as the Old God from the episode "The Rings of Akhaten" fed on stories. The people living in his system used items of sentimental value as currency so they could be given as offerings to it and taught their Queen of Years all the stories of their culture so that if it ever awoke he could feast on her rather than their entire system. They even believe that the Old God made the first life in the universe, possibly to create tasty stories for it to feast on.

Diablo: How tastes your fear, mortal!Raynor: I wouldn't know, I'm not sure you can actually taste fear.
- Grrl Power: Vehemence is "an innate user of vehemic energy ... sometimes called vistric energy." The layman's version:he gains power from violence. He makes his debut by sticking around an all out super brawl between a super hero team and a team-up of villains. Only when it's over does he enter the fray himself, now strong enough to go toe-to-toe with one of the most powerful super beings in the world and only making himself stronger for it.
- In Dan and Mab's Furry Adventures, the resident Succubi and Incubi passively feed on the emotions of surrounding creatures. They are able to eat souls, though probably most of them don't, since that would get them in trouble rather quickly. Also, the various clans each have one emotions they especially like, which include Pride, Pain, Anger, Lust and Joy. Because of their abilities, they are vulnerable to mental manipulation. For instance, you can remember being tickled "at" them, and they will react as if it were actually happening. They also don't need to sleep or eat when receiving enough emotional energy. However, they do enjoy coffee, ice cream and other 'treats' just like every other living creature, and they can sleep if they want to, although they do not dream. Emotional consumption apparently replaces the effects of REM sleep.
- Adventure Time has a few examples; a character who eats drawings from within the paper they reside, and Marcelline, a vampire who eats not blood, but the colour red.
