All the goodness of Mind Rape... with the bitter aftertaste!
When somebody is Brainwashed and gets better, but somehow part of the programming sticks and it shows by the character acquiring new personality traits, tics and/or quirks. For example, Alice is a mind controller who casts a spell on Bob to make him fall in love with her. Bob somehow breaks the spell, but whenever he looks at Alice now, he blushes and can't quite explain why. Maybe he's falling in love for real, but who knows for sure.
This can be used as a Plot Device to show that the character hasn't quite fully-recovered from his brainwashing. Maybe he has, but the idea of being somebody Not Himself makes him change... probably for the better. Can become a Family-Unfriendly Aesop when brainwashing is the only way for a character to change.
Also comes in other flavors:
- Laser-Guided Amnesia-flavor: Either by magic or any other mind-altering means (Time Travel, Reset Button, etc.). Alice makes Bob forget that he was ever in love with her, but somehow Bob still retains faint, lingering sentiments for her.
- Shapeshifting-flavor: Whether involuntary or self-induced: Bob gets transformed into a frog. After being brought back to normal, he retains his newly-acquired taste for bugs. Usually used as a gag.
Compare and contrast with More Than Mind Control, where the character more or less knows that he is/was being manipulated, but goes along anyway. See Cartesian Karma for when the residue may or may not have resided, but the consequences of their brain-washed actions are still quite valid, and Wistful Amnesia, where a memory-wiped character retains sentiments of the memories they lost.
- In R.O.D the TV, Anita becomes a bookworm like her sisters after she gets a part of The Gentleman's memories. Take note, Anita used to hate books.
- Or perhaps she just got a better understanding of Yomiko Readman and books in general.
- All of the girls Keima "conquers" in The World God Only Knows show signs of this. They just can't explain why they blush whenever the geeky otaku walks by.
- Mobile Suit Gundam SEED Destiny has Stella, an Earth Alliance Extended who is brainwashed so she freezes up whenever anyone says "die" and absolutely trusts anyone who says "protect". Due to her memories not being properly wiped between missions, her programming leads her to associate Shinn with protection, thus allowing her to remember who he is.
- Neo Roanoke has the amnesia-type: his original identity, that of Mu La Flaga, begins to re-emerge after he's brought aboard the Archangel. He finds Murrue inexplicably familiar, instinctively remembers the ship's communication codes, and eventually begins experiencing flashes of Mu's memories and using his old Catchphrase.
- In Sket Dance, Tsubaki took some time to get rid of cat traits.
- In the manga of Kenichi: The Mightiest Disciple, Miu, a kind-hearted and talented martial artist girl, gets captured by the Blood Knight Evil Mentor Silkwat Junazard and gets a combination of amnesia and brainwashing that conditions her into extreme aggression and bloodlust. Even upon being rescued and her memory restored, her bloodlust and aggression still lies subconsciously, often triggering when her emotions run high or when exerting significant effort in martial arts, even during a simple and safe training exercise. Part of this is because the bloodlust and aggression had always been a part of Miu. It's the main reason Junazard wanted her to be his disciple in the first place. Miu's grandfather trained her from an early age specifically to help her control it.
- Played for Laughs in Kisses, Sighs, and Cherry Blossom Pink. The second story involves a ghost accidentally possessing a girl and using the time to tell her crush, the school nurse, how she felt in life. When she leaves, the possessed girl ends up with similar feelings.
- This was the reason Bronze Tiger always declined to lead the Suicide Squad: he was afraid the brainwashing he received at the hands of the League of Assassins could kick in any time. Much later, Rick Flag consulted him on how to prevent the brainwashing he suspected he'd been subjected to from kicking in. As a result, some time later Wade Eiling's gambit against Amanda Waller fails and he finds himself missing half a brain.
- Judge Dredd: After Judge Kraken is captured following his participation in the Judda incursion, he undergoes an extensive deprogramming to counter the brainwashing used by Morton Judd. However, some traces of his Judda past still remain, which is later used by the Sisters of Death to bring Kraken under their own control.
- Grouchy Smurf in The Smurfs owes his grumpiness to this: In The Black Smurfs he was the first Black Smurf, who are notoriously belligerent, and because he was a Black Smurf the longest he remained grumpy after being cured. This isn't the case for the animated version, though.
- The Immortal Game: Even after Rainbow Dash is freed from the Insanity, she still feels subconsciously compelled to obey Twilight Sparkle, whose Superpowered Evil Side was the one to cast the spell on her in the first place.
- TRON fanon often plays this up in post-TRON: Legacy scenarios with Tron and that Rinzler programming. The residue ranges from massive guilt issues, VerbalTics, bizarre thought patterns, or even fits of madness where he attacks his allies.
- Between Exiled and Gatecrash Taylor was kidnapped and brainwashed by Heartbreaker as part of his plan to kidnap Dinah. Even after using her jealousy to kill him, Taylor still loved him. The stress of dealing with her conflicting feelings makes up a good chunk of her character arc, ending when the Rachni Queen helps purge his influence.
- Becomes a Plot Point in His Honor, The Mayor, Drew Lipsky. Kim is a Dented Iron after saving the world so many times and sometimes enters a fugue state due to all the Brainwash Residue building up in her head, turns out one of her repressed memories is actually important.
- The Return:
- Nabiki and Akane still have a significant amount of mental contamination after being enslaved and Mind Raped by Alexia and it takes a lot of work to salvage any of their original selves.
- Misako (Ryouga) had her previous identity completely lost and is, for all intents and purposes, a new person whose personality is based on nothing but Brainwash Residue.
- In G.I. Joe, the Baroness is kept under supervision because they can't remove the mind-controlling nanomites just yet. Prior to that, she is shown to have retained some of her "training" by being able to operate a gun pod.
- The main plot point of Inception uses a planted "idea" to change a person's outlook in life. This could be for the better (Robert Fischer views his father in a better light and avoids a possible energy monopoly with his company) or worse (Mal commits suicide thinking the reality she's living in is still a dream).
- Total Recall (1990). After Quaid breaks Melina out of the constraints one of the Recall machines, it seems just a bit of the Housewife programming made it though, but not by much.
Quaid: Are you all right? Are you still you?Melina: I'm not sure, dear.
- Captain America: Civil War: Due to Cartesian Karma, the Avengers are essentially the only people who aren't afraid of the Winter Soldier after the events of the previous movie. And if they were right not to be, they might not have torn themselves in half, but it turns out the reason Bucky's been in hiding ever since is that he knows he has brainwash residue. The Big Bad finds out the Trigger Phrase and uses it (over Bucky pleading with him to stop) to send him on a rampage, turning the Avengers' divisive but previously only philosophical argument over the Sokovia Accords into an active crisis.
- The shapeshifting flavor happens in Discworld, although it isn't involuntary, and Granny Weatherwax only "Borrows" an animal's body for some purpose, sharing it with the real animal for a short time. But after she's exited the animal's body, she still retains impulses from whatever shape she borrowed. For example, she stopped using owls to see at night because "You ends up for days trying to twist your head right round," and after she's borrowed an entire beehive, she declares, "I wantzzz a bunzzch of flowerzz, a pot of honey, and someone to szzzting."
- It's also noted that at least one of the people she made think they had been turned into a frog still enjoy swimming in a pond long after the spell wore off. He was grateful for getting a new hobby.
- In the Deryni works, Sean Lord Derry suffers from this, referring to nightmares he had after his captivity and torture at the hands of Wencit of Torenth. He reluctantly admits the nightmares returned years later in anticipation of Kelson's trip to Torenth for Liam-Lajos's investiture in King Kelson's Bride. This foreshadows Morag's reasserting control over his mind, control which is taken and used by Teymuraz.
- In the New Jedi Order, after Tahiri is rescued from an attempt to brainwash her into believing she was a Yuuzhan Vong, it became a running subplot for several books that she retained most of the false memories subconsciously and under moments of extreme stress would adopt Vong mannerisms or even spout the Vong language. It was eventually revealed that the brainwashing had failed to overwrite Tahiri's original personality but had succeeded in creating a Yuuzhan Vong personality, Riina, who was almost totally independent of Tahiri's own mind. They ended up combining into a third personality to avoid going incurably insane.
- In Everworld, Senna's power over David is a blend of this and More Than Mind Control—he's attracted to her without any love spell, and he desperately wants to prove himself by "saving" her, so even when she's not actively enchanting him he's never very objective about her.
- Happens in Warehouse13 after Leena is saved from being brainwashed by McPhearson.
- In an episode of Star Trek: The Next Generation, Lt. Barclay got a brain upgrade by some aliens, which went away after it was no longer needed. Later, he and Troi were in Ten-Forward and he saw a chess game, moved a piece and said "Checkmate in three moves."
Troi: "Reg, I didn't know you play chess."Barclay: "I don't."
- Crichton from Farscape has Scorpius residue for ages after getting his chip removed (overlaps with Imaginary Enemy).
- In the original V (1983) miniseries, Diana has attempted to brainwash Julie Parish into being her slave. She fights off the brainwashing, mostly successfully, but occasionally catches herself using the wrong hand. In V: The Final Battle, Diana telepathically commands Julie and she has flashbacks to the brainwashing. Julie doesn't quite give in, but the internal struggle gives Diana a chance to escape.
- In the Buffy the Vampire Slayer season two Halloween Episode, Xander was turned into the soldier that he was dressed as for Halloween, complete with military training. Afterwards, Xander still retains some of that knowledge, which comes in handy in later episodes (such as when he sneaks into a military base to steal a rocket launcher).
- Also, after Dracula Renfield-ised Xander in season five, Xander still referred to Dracula as "Master" several episodes later and in the Season 8 comics.
- Falling Skies has a lot of this with the rescued teens. The harnesses are removed, but the spikes can't be removed without killing the kids. Between that and the unknown effects of the ordeal, Ben, Karen, and a few others are experiencing this.
- Power Rangers has a couple of examples.
- Fringe has Olivia retaining the expert (as in Olympic medal winning) marksmanship of the person she was brainwashed into believing she was even after she regains her own memories.
- Echo shows signs of this in early episodes of Dollhouse, remembering details of each personality she is imprinted with after they are supposed to have been wiped. Eventually, they evolve into a Mind Hive personality distinct from each individual one as well as Caroline, her body's original occupant.
- NieR decides to save Kainé at the cost of his own existence in the final ending. When she comes to, she starts crying when she finds the flower Nier gave her, but can't remember who it was from.
- In The King of Fighters, Ash sacrifices his existence to prevent the entire Ash Saga from happening. None of the other characters remember him, except for Elizabeth, due to having his Tragic Keepsake.
- Final Fantasy VII: Even after Cloud, who absorbed and/or assimilated Zack's memories, regains his real memories, he retains Zack's fighting style and some of his mannerisms. Although he reverts to his real personality and becomes more comfortable with showing his insecurities, he occasionally still puts on Zack's cocky act in front of the others.
- Funnily enough Call of Duty: Black Ops plays with some brainwash residue. When Mason escapes from the Soviet Union and gets back to the US, he experiences flashes, seeing and hearing numbers, seeing a hallucination of Reznov despite him being dead and even what looks like scenes of drawing a gun on the president, really the brainwashing hasn't worn off yet.
- This extends to Call of Duty: Black Ops II - at the end of the second 1980s level, Mason encounters Lev Kravchenko, previously presumed dead in Vietnam. During the next scene, he has to actively suppress an urge to execute him on the spot so that Woods can get some useful information out of him.
- Star Control Origins has the Free Trandals, a subset of the Trandals who have freed themselves from the mind-controlling AI known as Overmind. They frequently say things that Overmind might say out of habit, before hurriedly correcting themselves.
Player: Ok, we'll be going now.
Free Trandal: Not in that state, husks! First we must— ah, um, s-sorry. Sorry. Farewell, friends.
- In Chapter 34 of Gunnerkrigg Court Jack claims to be in love with Zimmy, and attributes it to a remnant of his possession by a ghostly spider obsessed with Zimmy which tried to take control of his mind. This doesn't seem to worry him.
- In Squid Ops, main character Mui brainwashes her sister using some hypnotic squid ink (yes, It Makes Sense in Context) that makes people obedient to her. The first thing she tells her to do is to answer with "Yes, Mui. I obey." whenever Mui gives her a command. Later, after the effects of the ink wear off, Mui brings her sister some lunch and says "Take it and don't be mad, okay?" Lena reflexively replies "Yes, Mui. I obey."
- Galaxion: After spending a couple of hours breaking out of Miesti control, Zandarin and Aria seem to have acquired telepathy. He copes, but she's freaked out.
- In Ben 10: Alien Force, Albedo is an villain who copied Ben's appearance and Omnitrix. He also gained some of Ben's characteristics, like eating junk food (especially chili fries). After having his Omnitrix broken, stuck with Ben's color-swapped form, and taken to prison, he shouts, "BRING ME CHILI FRIES!!!" Word of God says this is actually Albedo in denial and he does genuinely like them, but finds the idea appalling nonetheless.
- In Batman Beyond: Return of the Joker, Tim Drake still has aftereffects of his last encounter with The Joker (of the 'uncontrollable shaking and bad dreams' kind) after 40 years. Given what The Joker put him through, that's really not that surprising.
- Albeit some of that can be clarified as the Joker's mind chip on him. For example, his disdain and regret for being Robin was a result of the Joker's chip beginning to affect him. Once it's gone, so is any disdain toward his past. He actually didn't blame Bruce or Barbara and did enjoy being Robin.
- A variant in Gargoyles—in one episode, Broadway and Angela are willingly possessed by the ghostly lovers "Othello" and "Desdemona"; not long after, the two become an Official Couple. Word of God notes that it's open to interpretation that the possession might have kick-started their attraction to each other.
