--->'''Fingers:''' Where is my mother?!
--->'''Van Dyle:''' I p-probably sold her.
--->'''Fingers:''' ''Probably''?
--->'''Van Dyle:''' I don't know, I don't keep track!
--->'''Fingers:''' She was my ''mother''!
--->'''Van Dyle:''' ''(clearly terrified)'' To me it was just another gorilla.

** The first Hunter was Gillecomgain, who was just some farm kid when Demona casually mangled his face after he caught her stealing food. He made a mask to highlight the scars and began hunting her relentlessly. Several decades later, she finally overpowered him and unmasked him before giving the finishing blow. He stared at her and asked if she now understood why he hunted her for so long. Demona flatly replied, "No." This made him angry, of course. The man's descendants began a thousand year blood hunt for her, and she ''still'' doesn't know why (not that she would care anyway). In a deleted scene from "Hunter's Moon: Part Two", the leader of the latest generation of Hunters confesses to Elisa that no one in his family remembers how or why the hunt began, either.

** Because Zucco killed Dick Grayson's parents and earned a RoaringRampageOfRevenge from Batman and Robin. Of course, Zucco's a member of TheMafia, he's killed plenty before.

* In ''{{The Spectacular Spider-Man}}'', Mysterio is disappointed that Spider-man doesn't remember him.

* Speaking of whom: The version of Quentin Beck from ''WesternAnimation/{{Spider-Man The Animated Series}}'' became Mysterio to get revenge on Spidey for exposing an unethical stunt he pulled while shooting a movie. He doesn't mention it at first, but when he does Spidey has no idea what he's talking about until Lieutenant Terri Lee looks it up.

---> '''Gypsy woman''': How's that ''curse'' I ''cursed'' you with, ''Cursed-y?''

-->'''Zucco:''' Don't tell me what I gotta worry about. I'm not back in town five minutes-- five minutes-- and he's on my tail. You don't know the bat. He don't let up! He's the dark angel of death, man, and he wants me!\\

** Also, in ''Ben10Omniverse'', with [[RememberTheNewGuy Billy Billion]], a former classmate who was [[GreenEyedMonster envious of Ben when they were eleven years old]] and [[DisproportionateRetribution tried to zap Ben in Dimension 12]], resulting in [[HoistByHisOwnPetard him ending up trapt in that dimension after he tried to shoot at Diamondhead]]. Turns out Ben not doesn't remember him, he ''[[UpToEleven wasn't even aware of his existance]]''.

* In ''BatmanTheAnimatedSeries'', "Robin's Reckoning, Part 2":

** The first Hunter was Gillecomgain, who was just some farm kid when Demona casually mangled his face after he caught her stealing food. He made a mask to highlight the scars and began hunting her relentlessly. Several decades later, she finally overpowered him and unmasked him before giving the finishing blow. He stared at her and asked if she now understood why he hunted her for so long. Demona flatly replied, "No." This made him angry, of course.

In a deleted scene from "Hunter's Moon: Part Two", the leader of the latest generation of Hunters confesseses to Elisa that no one in his family remembers how or why the hunt began, either.

** Subverted in [[WesternAnimation/BatmanTheAnimatedSeries The New Batman Adventures]] episode ''Joker's Millions''. SelfDemonstrating/TheJoker throws a party that Bruce Wayne attends, Joker offers Wayne some champagne, which Wayne refuses, citing the fact that the last time the two met, Joker threw him off a building. Despite only happening a month ago (in-universe), The Joker doesn't seem to remember the incident at all. It turns out [[spoiler:the Joker that Wayne was talking to was a body double in the real Joker's employ]].

::: This actually [[HoistByHisOwnPetard bites Homer in the butt]]: when Mr. Burns regains consciousness after being shot, all he can say is "Homer Simpson" over and over. Though ironically, he still doesn't recognize Homer.

*** Of course, he does ''remember'' Canmore, he just doesn't recognize him. It's been, what, twenty years?
**** 17 years, they [[ShownTheirWork paid a lot of attention]] to getting the dates of Macbeth's reign historically accurate

-->'''Blight/Derek Powers''': Who are ?!\\

** One episode has Homer meeting universal ButtMonkey Frank Grimes and driving him to suicide. In a later episode, Frank Grimes Jr. shows up to get revenge and Homer can just barely recall the incident, ending cheerily with "How is old Grimey?" Needless to say, Grimey Jr. is quite upset.

---> '''Gypsy woman''': How's that ''curse'' I ''cursed''' you with, ''Cursed-y?''
---> '''Homer:''': I know you don't remember me, but...

* At the ''BatmanTheAnimatedSeries'' episode ''[[Recap/BatmanTheAnimatedSeriesTheClockKing The Clock King]]'' this trope is Justified, or Deconstructed or maybe Parodied? When Fugate, now the ClockKing, tries to remind Hill of his AdviceBackfire that led to his StartOfDarkness, Hill doesn’t know what he is talking about, and [[UnknownRival he doesn’t recognize Fugate]] until his DramaticUnmask. Then he argues rightly that he was JustTryingToHelp (and the real reason he doesn't remember Fugate is because he was only an acquatiance on the subway and he hasn't seen her in seven years). Being a GenreSavvy villain, Fugate doesn’t care in the least and tells him PrepareToDie. Did we mention this episode is the GenreDeconstruction of the ''BatmanTheAnimatedSeries''?
-->'''Batman:''' Give it up, Fugate! [[ShaggyDogStory Hill committed no crime against you!]]\\
'''Temple Fugate:''' [[FelonyMisdemeanor He did worse than that!]] [[HarmonyVersusDiscipline He made me late!]]

-->'''Blight/Derek Powers''': Who are you?!\\

*** This example is a bit odd in that it seems it was a bit of a Tuesday for Zuko ''and'' Sokka. While he was obviously present for the whole episode, Sokka apparently remembers Suki but ''not'' Zuko setting fire to her village. Maybe justified because Zuki gave Sokka his SacredFirstKiss?

** [[TheDragon Princess Azula]] shows herself to be this type of villain when her {{plan}} against her brother begins to take shape in Season 3. You can almost see her going through the exhaustive list in her head of My-Current-Diabolical-Plots-In-Motion-Against-Zuko.

* ''Ben10UltimateAlien'' provides a heroic example. In ''WesternAnimation/{{Ben 10}}'', Zombozo was a {{Nightmare Fuel}}ed EmotionEater whom Ben [[WhyDidItHaveToBeSnakes was absolutely terrified of]]. When the MonsterClown reappears 6 years later as the leader of a VillainTeamUp, Ben claims he doesn't even remember him ("We've fought him before?"). DwayneMcDuffie [[WordOfGod has stated that]] Ben does remember but doesn't want to admit he used to be scared of clowns.
