* In ''Film/SantaWithMuscles'', Hulk Hogan pretends he's Santa Claus and gets amnesia while in the suit.

* In ''How To Conquer the World'' the unnamed protagonist hits his head at a costume party and is taken home. When he wakes up with amnesia (and a headache) the next morning, he takes one look in the mirror at his costume and the nametag which says "[[MorallyAmbiguousDoctorate Doctor Evil]]", decides he must be a MadScientist and sets off to conquer the world. The fact that his few coherent memories are of a drunken rant about world domination he was making to impress a stacked blonde doesn't exactly help.

* A variant in ''VideoGame/GhostTrick''. [[spoiler: The protagonist, a recently dead ghost, looks like a blond-haired man in a red suit because that's the first corpse he saw and he assumed it was his. It's not, that body in fact belongs to the BigBad, and we don't find out until the end that the protagonist was originally a ''cat''. The unfamiliarity with human concepts he chalked up to amnesia was really because he was never human to begin with.]]

* ''Series/BuffyTheVampireSlayer'': In ''Tabula Rasa'', Spike wakes up with amnesia in a stolen suit coat with a note addressed to "Randy" in the pocket. Being Spike (and therefore British), he's furious that Giles (whom he assumes to be his father) would name him that[[note]]"Randy" being slang for "horny"[[/note]].

* One ''Franchise/{{Batman}}'' comic starts with Batman waking up, only remembering who he is on seeing his outfit. He travels through Gotham, and manages to intimidate at least one crook into abandoning his initial plans, but when he tries to stop a larger crime he's quickly beaten down. Then the ''real'' Batman shows up, explaining that the man we've been following since the beginning is an ordinary citizen (who likes to get kinky in the bedroom). He and his wife were roleplaying a RescueRomance scenario when the man hit his head, resulting in the comic's events. Batman leaves, but asks that they stick to Superman outfits from then on.
* ''ComicBook/{{Soda}}'': One story has Soda suffer a milder form of amnesia in which he doesn't forget who he is, but what he does: instead of a cop pretending to be a pastor for the sake of his sensitive mother, [[OOCIsSeriousBusiness he acts like an actual pastor, condemning the violence of his fellow cops and being nice to his mother's evil cat.]]
* In one ''[[ComicBook/SupermansPalJimmyOlsen Jimmy Olsen]]'' comic, Jimmy is in disguise while on the job and hits his head.

* ''Series/StarTrekTheNextGeneration'' episode "Conundrum". After an alien ship scans the Enterprise, all of the crew members develop amnesia. Worf assumes that he's the captain because he's wearing his decorated Klingon sash.

* In ''Machinima/TheStrangerhood'', Sam (who, like the rest of the cast, has no idea who he is or why they're suddenly living on the eponymous street) is able to find out his name because it was written on his underwear. [[spoiler: In the finale, it turns out that this isn't his real name (and those weren't his pants)!]]

** Somewhat related: Anya is wearing her engagement ring from Xander, but assumes that she and ''Giles'' are together, since they also find paperwork showing that they co-own the magic shop.

** Inverted in the story "Danger From The Stars!". Superman tries to stop a meteor with some Kryptonite in it, he gets hit on the head, and falls down to a costume ball. He figures he was just attending the party, finds his civilian clothes in a pocket in his cape, and assumes [[ClarkKenting his glasses]] [[PurelyAestheticGlasses are just to prevent eye fatigue]]. [[AmnesiacResonance He goes to the Daily Planet, figuring a newspaper would cover an event like the ball]], where he learns about his Clark Kent identity and his job, and how Superman was his "friend." He later discovers that he has Superman's powers, and [[WhatAnIdiot instead of putting two and two together comes to the conclusion that Superman's powers came from his suit and that Superman gave it to him to finish up the meteor job]].
