Alice has a handicap or deformity. And we're not talking [[InspirationallyDisadvantaged inspirationally]] or [[HandicappedBadass awesomely]] disabled here. We're not playing it for quirkiness or to make her stand out. This disability is a genuine handicap which makes Alice's life harder, and perhaps even affects her self-image and sense of worth. For purposes of illustration, let's say Alice has no hands.

Bob loves Alice, and is dismayed by her sadness over her handicap. So Bob takes Alice's face tenderly in his hands and tenderly tells her "Do not worry, I will be your hands."

And Bob makes good on his promise. Bob feeds Alice, he applies her make-up, he writes her letters, dresses her. Hell, he becomes so familiar with Alice's quirks and behavior that he can even anticipate her, cupping her mouth when she yawns, holding a finger to her nose when she's about to sneeze, scratching her where she itches before she even tells him.

This trope is a character compensating for another character's disability or deformity by basically becoming the appendage the other person is lacking. This altruistic attitude is usually attributed to, at least, a bond of friendship, and often is borne out of genuine love, be it brotherly, parent-child or romantic.

Compare TheCaretaker. Not to be confused with HelpingHands (although its entirely possible for HelpingHands to be a HandyHelper).

* Used and brought to a mentally scarring twist ending in ''FrankenFran''.
* In ''Manga/FullmetalAlchemist'', Colonel Mustang fights Father while blind, with Lieutenant Hawkeye serving as his eyes.
* At the end of ''Anime/ElHazardTheMagnificentWorld'', the hero and the chick cooperate like this - he wields the sword while she helps him with her ability to see through illusions of the BigBad.
* In a chapter of ''Manga/BlackJack,'' an aspiring sushi chef is accidentally hit by a truck driver and loses his arms. To make amends, the driver offers to help the chef by serving as his hands. However, in a cruel twist of fate, the truck driver is himself killed in a traffic accident. Black Jack ends up grafting his arms onto the sushi chef.

[[folder: Film ]]

* In ''SantaSangre'', protagonist Fenix quite literally is his mother Concha's arms and hands, as he stands behind her and uses his hands as her own, to the point that they almost move without his conscious thought. [[spoiler:Which is actually true, since when Concha commands her to kill The Virgin, Fenix literally cannot stop his hands from doing so.]]
* In ''Film/MadMaxBeyondThunderdome'', Master is an intelligent-yet-physically-weak midget. The strong-yet-dim Blaster (he has Down Syndrome) serves as Master's arms and legs.
* In ''OnceUponATimeInMexico'', [[spoiler: Agent Sands]] is blinded and has to rely on a street kid he met earlier to guide him around.
* In ''The Bone Collector'' [[spoiler:Amelia takes over the job of of Rhymes and kills Thompson]]
* In ''TheIncredibleMrLimpet'', the title character loses his glasses, so his crab friend Crusty becomes his eyes.
* In ''WesternAnimation/{{Ratatouille}}'', Linguini is a bad cook bordering on [[LethalChef lethal]]. Remy is a good one, but he also happens to be a [[WhatMeasureIsANonHuman rat]]. They discover that if Remy hides in Linguini's hat, Remy can smell the ingredients and direct Linguini to choose the right ones by pulling his hair.
* In ''Film/{{Blindness}}'' a woman who is immune to the virus causing blindness helps guide seven blind people.
* Alana is arguably a little bit like this for Bethany in ''SoulSurfer'' in some ways. On her facebook site Bethany as much as called her that in RealLife.
** Arguably a subversion. Bethany manages to get along reasonably well. What she does get from friends and family is encouragement.
* A mutual example in ''Film/SeeNoEvilHearNoEvil'': Dave is deaf, Wally is blind. Dave acts as Wally's eyes, Wally conveys information to Dave through lipreading.

[[folder: Literature ]]

* In ''TheSharingKnife'' series, Dag is one-handed. Normally this isn't a problem for him, but when he breaks his other arm, his then-fiancée Fawn ends up acting as his hands.
* In the ''LittleHouseOnThePrairie'' series, Mary is stricken blind and her sister Laura becomes her eyes by describing everything she sees for Mary's benefit whenever she asks.
* ''Gathering Blue'' provides a proposed mutual example. [[spoiler:Kira's father turns out to be alive despite his being LeftForDead before Kira was born and now lives in a village where people with disabilities all live this way.]] He is blind and offers Kira the chance of coming with him to his village, with Kira as his eyes and him as her legs (Kira has a deformed leg).
* In [[Literature/TheBible The Book of Exodus]], Aaron serves as his brother Moses's speaker, since Moses has a speech disability.
* Magpie and Dog in ''Fox'' by Margaret Wild. Magpie's wing was injured in a forest fire, and Dog has only one eye, so Magpie rides around on Dog's back being his binocular vision, and when he runs it's ''almost'' as good as flying.
* ''Literature/BenHur'' has a mutual example. When Simonides and Malluch meet in the dungeons and are both released, Simonides acts as Malluch's tongue and Malluch acts as Simonides' legs.
** In the film version (not sure if it's in the book) Simonides says "together we make a considerable man".
* ''FreakTheMighty'' (and of course the movie adaptation, ''The Mighty'') is a mutual example of this. Freak is brilliant and outspoken but frail, while Max is big and strong but none too bright; together they can face down just about anybody.
* At the end of the ''[[HeraldsOfValdemar Mage Storms]]'' trilogy, Karal's eyesight is burned out. He can only see through his mind link with Altra. When Natoli writes to ask him to return to Valdemar, she says "I can be your eyes too" (not literally, as she doesn't have any PsychicPowers).
* Invoked in ''Literature/FateZero''; when [[spoiler:Kayneth]] becomes crippled as a result of getting shot by Kiritsugu's Origin Bullet, [[spoiler:Sola-ui]] offers to become [[spoiler:Lancer]]'s new master, whether forcefully or otherwise.

[[folder: Live Action TV ]]

* In ''Series/StarTrekTheNextGeneration'' Riva a diplomat is deaf from a hereditary genetic deficiency, but has his "chorus", an entourage of three people in telepathic communication with Riva and able to enunciate his thoughts. This trope is repeated in the same episode when [[spoiler:Riva's "chorus" is killed and Data must read his sign language and translate for him]] This happens in another episode of ''[[Series/StarTrekTheNextGeneration Next Gen]]'' where [[spoiler:[=LaForge=] and a Romulan lose the use of some of their senses due to interference from the planet Galorndon Core, and compensate for each other's lost senses]]
* ''Series/RedDwarf'':
** Spoofed in season I when, after being brought back to life as an [[IntangibleMan hologram]] Rimmer asks Lister to be his hands. Lister refuses on the grounds he knows the type of things Rimmer liked to touch.
** In a season VII episode Lister has lost an arm, so Kryten does everything for him, including things he could still do, like wiping his mouth with a napkin.
* In ''{{Firefly}}'' Simon Tam is River's Amygdala built for two.
* Sue Thomas' dog in SueThomasFBEYE

[[folder: Tabletop Games ]]

* Subverted in TabletopGame/DungeonsAndDragons - The naga are a race of snake-headed humans and most of them cope just fine, either through dextrous mouths or magic. However, they do notice the trope and consider it a proof that they are a superior race - after all, they are best suited for thinking, while lesser creatures serve as their limbs - so this must be the intended natural order.

[[folder: Webcomics ]]

* In ''WebComic/{{Wurr}}'', the resident IllGuy Sinjal is carried around on his packmates' backs.
* ''Webcomic/{{Goblins}}'' has a double example; Pan the Ogre is blind, while his companion Yala the Kobold is mute and has had her legs amputated. Pan permits Yala to ride on his head, and in return Yala acts as his eyes, touching his head to indicate which direction she thinks he should walk and warning him of danger.

[[folder: Real Life ]]

* Service dogs; depending on what type they are they act as their handler's eyes, ears or even hands (well, in a manner of speaking).
