What Happened to the Mouse?/Video Games


 * Super Mario franchise:
 * What happened to the Mushroom King, Princess Peach's father?
 * At the end of World 5 of Super Mario Galaxy 2, Bowser Jr. is blasted out of his malfunctioning Boomsday Machine, and is simply never seen, heard from, or mentioned again afterwards.
 * In Paper Mario: The Thousand-Year Door Despite both directly controlling Bowser throughout the game, and him and Kammy being main characters in the story, the two are never mentioned in the Where Are They Now? Epilogue that shows Gombella's e-mail where she tells Mario what everyone is up to. The last time Bowser and Kammy are ever seen in the game is lying in defeat before the final boss after your boss fight with them, and they vanish after you leave the room and are never mentioned during the ending at all.
 * In Super Paper Mario, upon first meeting Dimentio, Tippi recognizes him instantly. How she knows him is never explored any further. Even in their spoilerific backstories, there doesn't seem to be any mentioned reason as to why she would know him.
 * In Super Mario Sunshine,
 * Bowser Jr. mentions that he got the Paintbrush from "a strange old man in a white coat" as the camera focuses on the E. Gadd logo on F.L.U.D.D.'s side. We never find out if Bowser Jr. stole the Paintbrush from Professor Gadd or if Gadd gave it to Bowser Jr. It's believed that Gadd invented the paintbrush for Mario to use, and the only reason Bowser Jr. has it is because Gadd gave it to him while he was disguised as Shadow Mario, with Gadd mistaking him for the real Mario.
 * Then there's Il Piantissimo. The ending of the game shows him finding the Magic Paintbrush, possibly setting up a Sequel Hook. He's never seen again.
 * The Elder Scrolls III: Morrowind: What happened to Jiub?
 * According to fanon (and a few fan-made addons) he became Nerevarine's companion in the quest. Also, in the Elder Scolls IV: Oblivion, asking certain characters about rumours will reveal that Jiub has become a saint in Morrowind. And why? Because he drove the Cliff Racers out of Morrowind. Hell yeah.
 * They also say that he was killed by the Daedra during the invasion.
 * Bully: Who won class president? Earnest or Ted?
 * The fourth case of Phoenix Wright: Ace Attorney: Trials and Tribulations revolves around a murder committed during the hostage exchange of  for a two million dollar diamond. Much is made of the fact that   disappeared along with the diamond after the murder, but while the former is found easily the latter is never recovered. One could assume   sold it, but that doesn't explain why the thief doesn't have two million dollars sitting in their bank account somewhere and it's not brought up again.
 * The first game caused an accidental disappearing mouse. In the fourth case von Karma makes a throwaway reference to having a daughter whose child has a dog named Phoenix. In the second game we meet his daughter Franziska, who does not have any children. While this was probably not intended, many people are left wondering who the mysterious older von Karma daughter is.
 * Of course, Von Karma could just be lying.
 * There is also the missing 4th clue from the final case in Justice for all, that Franziska took with her abroad and promised to return to Wright when they meet again. She never did give it to him in the next game Trials and Tribulations
 * In the third case of the first game, Sal Manella disappears after his testimony, and is never mentioned again after.
 * Chrono Trigger, where the fate of the character is unexplained/occurs off-camera. The resurfacing of the subplot in Chrono Cross may or may not have been planned beforehand.
 * A better example is what happened to Magus, Schala's brother. In Chrono Cross, the character Guile was supposed to be Magus still searching for his sister but Square dropped it during development. There are still several scenes from the game that Square left in from this plotline. The most obvious is a letter from Lucca that suggests that Janus (Magus' real name) was travelling with you. Of course considering what happened to the rest of the cast from Chrono Trigger this might be a good thing.
 * In the new DS game, Magus,
 * In Chrono Cross, the scene where Kid declares that Terra Tower has assumed its true form, after which nothing is ever mentioned of it again. It just floats there menacingly for the rest of the game.
 * The Legend of Zelda franchise:
 * In Zelda: The Wand of Gamelon, Princess Zelda is constantly accompanied by her nanny Impa, who mysteriously vanishes near the end of the game and is simply never seen, heard, or mentioned again.
 * The entire premise of The Legend of Zelda: Majora's Mask is that Link has been detoured from his quest to find Navi. After he saves Termina, Tatl says that he should get back to what he was doing. How does he get back to Hyrule, and did he ever find Navi?
 * Warhammer 40,000: Dawn of War ends with Brother-Captain Gabriel Angelos swearing to . Neither Gabe nor have been seen for the three expansion packs nor the sequel. Since this occurs at the end of the game, it also counts as Left Hanging.
 * The real cause is an unfortunate round of Executive Meddling attempting Status Quo Is God. In this case, Gabriel was such a popular character that GW has introduced him into the official background lore of the game as Chapter-Master of the Blood Ravens... and so he couldn't be used in the Dawn of War games because it would mess up the lore. Gabe's story is continued in the Dawn of War books, although he ends up dealing with Necron and Chaos, rather than.
 * Finally averted in the "Retribution" Expansion Pack to Dawn of War II, set a decade after the events in Chaos Rising.
 * Magical Starsign has a pretty odd one; at the Starfall Festival event, a breather not-quite-cutscene, you can wander around and talk to the individual members of your party. The event only ends when you talk to Mokka the robot (if the player character is a girl) or Lassi the rabbit girl (if the player character is a boy}. They're just about to admit to being in love with you, but your clueless Heroic Mime will be hijacked by another character and poor Lassi/Mokka will confess their feelings into thin air. Before and after that, nothing. No further acknowledgement, nothing in the epilogue. Cue a massive "Huh? Why was that even put in there?" on the player's part. It could just be part of Magical Starsign's odd humour, but the nature of the scene hints that this development has a significance the game never gives it.
 * This issue pops up with Pico and Sorbet's blooming romance as well. It's pretty obvious that Pico is in love with Sorbet, and in one cutscene, they have a touching moment together, but  and that little subplot remains unresolved.
 * Leafos' family history in ~Viva Piñata~ looks like a plotline, but it never actually goes anywhere. You should, for example, be able to work out that Stardos is, and Leafos alludes to this...but you can't really do anything about it, or even receive further clarification beyond unlocking the diary entries as you level up. There's no way to bring the dysfunctional family back together (maybe you wouldn't want to...) no matter how good your garden in...and despite the long, involved history in the diary that seems to indicate that their problems are intrinsic to the game.
 * In Naruto: Clash of Ninja Revolution 2's storyline, disappears after Jiraiya defeats him. We never even find out if.
 * Corporal Adrian Shephard is the protagonist of Half-Life: Opposing Force. At the end of the game he gets Put on a Bus by the GMan, who was impressed at his survival skills. Cue Half-Life 2, and Shephard is the only character who has yet to make an appearance. Valve has recently gone on-record saying they've noticed how much of a fan-favorite he is on account of how vocal the fanbase gets about this particular mouse, so we might see him again.
 * Opposing Force was developed by Gearbox Software, so Valve may not own that character or may not consider him canon. The Race X enemies haven't reappeared either.
 * The Final Fantasy series has its share of dropped sidequest threads:
 * Banon in Final Fantasy VI. He starts out as leader of La Résistance against The Empire in the World of Balance, but is never mentioned in the World of Ruin. The most likely explanation is that he died in the apocalypse, but this is never confirmed.
 * In Final Fantasy VIII, the Big Bad is defeated and all of the characters live happily ever after; everyone seems to have forgotten that the city of Esthar is still overrun with monsters from the Lunar Cry. Attentive players will note that the Lunar Cry is a recurring natural disaster, but that's only a flimsy justification.
 * Final Fantasy IX:
 * Much of Freya's backstory concerns her search for her lost boyfriend, Fratley. She finally finds him again about a quarter of the way through the game, only to discover he has amnesia. He then heads off before Freya can say much to him. Typically, one would think that he would reappear later and the plot would continue when he does, but no, it never happens. He appears again in the ending sequence (still amnesiac), but this seems like a hastily-added attempt at covering up the planned-but-deleted sidequest.
 * A very well-hidden quest reveals Garnet's childhood name, to the amazement of the cast. And then it's never mentioned again.
 * In the newest Prince of Persia game, the main character begins it by losing his donkey, Farah. He's wandering around, calling for her when he runs into the princess. Although she is occasionally referenced Farah is never seen.
 * It is later explained in the credits of the EDC for the game.
 * A comedic example in Fallout 2; you can take up a short treasure hunt, which culminates in lowering a treasure-hunting dwarf down a well to retrieve a bag of loot. It turns out to hold a fortune in bottlecaps, the now-worthless currency of the previous game. After cursing, kicking a bit of dirt and ultimately having a good laugh about it, you head off again, leaving the dwarf stuck down the well.
 * A possible fate of Follows-Chalk in Fallout: New Vegas if you convince him to leave tribal life to see civilization for himself.
 * Quite famously within the fandom, you never do rescue Sulik's sister, find Sulik's village, or any trace of the slaver group that kidnapped her.
 * What was with Kamyu's blood drinking, spirit talking and... other nighttime activities, anyway? Presumably they were supposed to be foreshadowing for Mutsumi but... she didn't do any of that stuff either. And it's not like the original her even could have done anything like that. Plus, It seems doubtful that she would do anything like she did if she's supposed to be being influenced or something.
 * Resident Evil has a very bad habit of doing this. Rebecca, Billy, Carlos, and all the characters in Survivor and Dead Aim never have their fates revealed aside from "they survived". Barry, Hunk, and Sherry run very close into this, only having the epilogues in 3 reveal some things about what happened to them. In a nutshell, if you're in this series and your name isn't Chris, Jill, Leon, or Claire, the plot doesn't really give a damn about you.
 * Literally done in Resident Evil Code: Veronica. Twice in the game, Claire runs into a mouse (first hidden in a locker, the next in a secret room). In the unlockable minigame, you have a chance of finding the mouse's diary explaining everything that happened to him.
 * Sherry is back, now 22 years old, in Resident Evil 6.
 * Midway through Prototype, Alex's sister Dana is kidnapped by The Virus; Alex manages to rescue her from the epicenter of the outbreak, and drops her off with Doctor Ragland. Considering that Dana Mercer and Ragland were pretty much the only sympathetic characters in the entire game, the fact that neither one is seen again is a bit jarring.
 * Dana shows up again in Video Game/Prototype2, no worse for wear. Ragland's still unaccounted for.
 * Alex's fate is deliberately left unknown at the end of Golden Sun: The Lost Age. The fandom looked for his return in Dark Dawn.
 * Speaking of Dark Dawn, Psynergy Vortexes are a significant part of the very early plot, but you never hear one whit about them after you get Rief out of his box cage.
 * At the very beginning of Shadow Hearts, Yuri gets his arm ripped off and is able to reattach it, and it heals instantly. He never manifests this power again, and its origin isn't explained.
 * In the same sequence, Alice is shown to have a pendent which somehow repels evil spirits. We never see or hear about it again. She repelled the evil the pendant wasn't actually important.
 * The sex scenes in Kanon suffer from this. They happen and then they're never mentioned again (beyond the screen immediately afterwards), even if the follow-up scene would warrant a mention. Particularly glaring in Shiori's and Ayu's scenarios, where one of the characters reminisces about everything they've done together and mentions everything except the sex. Makes it kind of easy to make the clean version, huh?
 * In The Godfather, The Trojan is an original character who serves as one of your hit contractors. Unlike the various other original characters, he plain disappears after giving his last contract hit and doesn't receive any closure as to his ultimate fate.
 * Some extremely vague dialogue from Pete Clemenza suggests that The Trojan is working at cross purposes against the Corleone Family. This only comes about if you accept several missions from The Trojan and neglect Clemenza's contracts; at one point, you find Clemenza in the compound basement shooting empty beer bottles acting very upset. Only the farthest limb on the Epileptic Trees connects this to the character's actions, though.
 * Made more strange by the fact that in The Trojan's last hit he says he will be accompanying you, but he never shows up. A probably unrelated character named 'The Trojan' is on the family tree in the second film listed as being in prison for drug peddling so this may have been his fate.
 * Infinity series:
 * What was with the game of kick the can in Ever 17? don't explain that at all. Despite the Mind Screwdriver of the True End route it's still not clear what was going on there.
 * The true identity of the bodies discovered on Mt. Akakura in Remember 11 is never revealed.
 * Although Yuni implied that
 * Very early in the game, Mother 3 has one of the villagers accidentally break off the doorknob off of Flint's front door. It rolls off into the bushes, presumably never to be seen again.
 * Actually, if you've been talking to everyone like you should, you'd find out that the doorknob has been a lot of places. Salsa can even pick it up outside Osohe Castle.
 * Also, what happened to the Ultimate Chimera? The last we see of it, it's
 * Actually the UC makes another appearance afterwards, albeit not plot-relevant. When, one of the bathroom doors will, when "Opened" instead play the UC sound effect and have the door bulge out. You can then open the door for real and go inside to find the UC standing in front of a treasure chest that has a fairly good item inside if you can manage to run past the UC without it touching you.
 * From the same game, there's the Egg of Light. Early on, you retrieve it from the Osohe Castle, without its purpose explained. Then, while you're escaping the castle, you lose it, and only find it a few chapters later...at which point it never affects anything again. Its purpose is eventually explained, but as far as this troper can tell it's never used for said purpose. Ever.
 * In the World of Warcraft expansion pack Wrath of the Lich King, a val'kyr (undead valkyrie) named Annhylde the Caller shows up at the end of the Utgarde Keep dungeon to revive the boss Ingvar the Plunderer as an undead. After that? She vanishes, and does not appear again.
 * This is not surprising if you have played as a Death Knight. During the starter quests, a Val'kyr will typically help you once or twice after you die in battle and not be seen again. However, Annhylde's fate is revealed in Sylvanas's short story; she is one of a few surviving Val'kyr and.
 * In Burning Crusade, we meet Sabellian, a black dragon who helps the player defeat a Gronn. He survives the battle and disappears afterward. Two expansions later, the Fangs of the Father questline is centered around helping the uncorrupted black dragon Wrathion eliminate the rest of the Black Dragonflight. Despite Wrathion claiming to be the Last of His Kind at the end of the questline, Sabellian is neither killed nor mentioned to be dead, leading some to believe he may have survived. Of course, it's also possible he died offscreen and the player just doesn't find out.
 * Goriona, Warmaster Blackhorn's twilight drake mount in the Dragon Soul raid. She helps Blackhorn during the Skyfire battle, but abandons him and flees once her health gets too low. Despite explicitly surviving the encounter, she's not seen or mentioned again afterward.
 * In Grand Theft Auto III Donald Love just disappears. He does get brief appearances in both 80s Vice City and 90s Liberty City, but these take place chronologically before GTA3 (2001).
 * There was a rumor that he was originally supposed to be killed by crashing a plane into his building, which was removed for obvious reasons after 9/11, but this has been debunked.
 * The last mission you "do" for him--Donald's Disappearance--is only for the purpose of showing you that he's gone.
 * Subverted in Super Metroid. Samus can meet very friendly little animals in the game, including three monkey-like creatures and something resembling a dodo, both of which demonstrate new abilities she can do that aren't mentioned elsewhere in the game. As you escape after setting a time bomb powerful enough to blow up the entire planet, which would naturally kill them, you can take a very brief detour to the room where you initially found the Bombs and find them trapped there, where you can use your newly-acquired BFG to blast open a wall and free them. Of course, that fails to address how unintelligent animals like that escaped the explosion of the planet that occurred moments afterward. They appear in the later game Metroid Fusion, but no explanation is given as to how they survived.
 * It is established in the ending of Metroid Fusion that they are intelligent enough to use (at least basic) ship commands.
 * If you save them, you can see them flying off in what is assumed to be their own ship after the planet blows up. In Metroid Fusion you find them on one of the decks of the station, so it's assumed that either Samus brought them there for testing (since she was working with the scientists) or they were caught and taken there separately.
 * It's generally assumed to be the latter, since Samus' dialogue shortly after releasing them in Fusion implies that she hadn't known of their fate.
 * This has been a topic of discussion since the beginning of Tekken 3, just where is Jun Kazama? Her son Jin's entire motivation from the game he debuted in was to avenge his mother's "death"; the problem is in fact that he actually never saw Jun dying, and only assumed that after she stayed to fight Ogre as he ran away the God had her killed, (although the wrecked and burnt surroundings from the place she was fighting was a good indication). This doubt still persists in the 6th game of the franchise by adding more uncertainty in Jin's assumption on Jun's death, and the fact that Word of God refuses to say she is dead doesn't help either.
 * Actually, Jun being alive is a plot point which Namco have deliberately kept a mystery for dramatic effect. It is likely but unconfirmed that it will form a major part of the story later on in the series. The reason Asuka is in Tekken 5 is to be a scrappy for Jun so that (nearly) all the characters who were in Tekken Tag would be playable (in some form) in Tekken 5, as Namco had received a lot of flak for not including them in Tekken 4, people obviously missing the point of Tag being a compilation game and not a canonical sequel.
 * Given that both Asuka and Jun are in Tekken Tag Tournament 2 and Jun has a direct connection to the boss of that game, it's now painfully clear that Askua is not and never was going to be a replacement for anybody. Remember, too, that even if a Tekken fighter was dead, that doesn't mean that person is dead now... Bryan Fury, anyone?
 * And what happened to Kunimitsu?
 * It seems to be implied that she is in hiding--she stole from her tribe and Yoshimitsu presumably wants to kill her. In the non-canonical Tag he actually does kill her in one of the endings. Some of her moves were carried over to Raven, as well as Yoshimitsu.
 * According to Word of God, Jun Kazama and Kunimitsu are apparently in hiding (the only characters that have been Killed Off for Real were King I and Armor King ). Jun will be returning to the series in the non-canon Tekken Tag Tournament 2 (fan demand is also clamoring for Kuni's return), so there's a chance--as slim as it is--that these plot points will finally be addressed. The Reveal that is already seen by many as a possible backdoor to allow Jun back onto the roster of a future canonical game.
 * And the biggest mystery of them all, Kuma's second costume in the first two games is a polar bear. From the third onwards, (where Kuma is replaced by his identically named son) his second costume is another character, Panda. Nobody knows what happened to polar bear Kuma and it's never been mentioned.
 * "Polar Bear Kuma" was simply an alternate Palette Swap rather than an additional character. That's like asking what happened to the Heihachi who wore nothing but a bandage diaper.
 * Alex? Okay, he's marginal at best, but if Mokujin could make the cut for TTT2...
 * Granted, Mokujin's bio in T5 explains that he (re)awakens in response to great evils (Ogre in 3, Jinpachi--or more specifically, the devil controlling Jinpachi--in 5, Azazel in 6). Alex seems to have just fallen off of the face of the earth, which is made even more puzzling by the fact that Roger not only has a family (his wife and son appear as a duo starting in T5), but Roger himself is still alive and kicking as of T5 and T6.
 * In Valkyrie Profile: Covenant of the Plume, there's the question of Natalia's lost children. They're strongly implied to be, but the matter is never direct addressed, nor does it have much apparent bearing on the plot. Even though they meet on two of the game's story paths, and
 * The first Valkyrie Profile has an odd version, because you know what happens to the character, but no idea how. Lawfer's recruitment cutscene doesn't show or even allude to how he dies, but he ends up one of your Einherjar anyway once it's finished. The manga has him turn into a vampire and get killed by Arngrim, but this doesn't fit with the events of the game.
 * And early in the game, during Belenus's recruitment scene, Valkyrie comes across a name and keeps it in mind, yet we never see this vampire she was talking about.
 * Psychonauts: Wait... did Crispin get out of the insane asylum too ?
 * In Bioshock 2,  This has something to do with the designers shifting the plot around at the near-last minute, and likely changed who your helpers and enemies were.
 * She plays a major role and her fate is revealed in the downloadable mission pack as Subject Sigma's main ally. Although it's doubtful this was planned ahead of time so much as when they started writing the story for the mission pack, she was now simply conveniently available.
 * The Beetle is introduced at one point in Spider Man 2 Enter Electro as one of Electro's goons, as well as a potential boss character. After his initial appearances he's never seen or heard from again.
 * In Persona 3, the next-to-last boss is, whom SEES defeats to the brink of consciousness, but doesn't outright kill. , then comes back to laugh in the party's face when ... and nothing is ever said about ever again, even though he.
 * Then again,
 * Cave Story: The Korons. Their kidnapping is a major motivation for their adoptive mother, Curly--until the Core fight, after which Curly never mentions them again. While the Korons themselves do get rescued by Momorin and Itoh, there's no logical way that Curly could know this.
 * Jack's fate is implied rather than shown: He's in the Plantation jail along with Sue, then he's gone by the time the plot forces you to get thrown in jail. The implications aren't pretty. However, it's possible to completely skip seeing Jack in the cell, rendering his disappearance from the game rather more baffling.
 *  ~Star Ocean: The Second Story~ : A rather large (if technically optional) aspect of the first part of the game involves you finding an ancient text in Cross Cave and showing it to a linguist named Keith. Keith finally takes it and begins studying it, but before you learn anything about it, . You never find out what was actually in it, making several long-winded events and dungeons seem annoyingly pointless.
 * It's revealed in Bowman's solo ending that the text is a myth about an 'ancient paradise' called
 * In the original Star Ocean it's strongly implied that Marvel is actually Ioshua's missing sister, and you later find said sister's body in seeming suspended animation -- in fact, one of the big clues to Marvel's identity is how strongly she reacts to this discovery. However, there is no way to actually confirm that Marvel is said sister or restore her to her original body, so nothing ever comes of it. This was finally addressed in the PSP remake.
 * The Sims had a lot of these. Sims 2 had Bella Goth, who was later lampshaded.  For a long, long time there, and yet she seemed like such a big character in the original game (and seems to be a mascot, of sorts, too). A more prominent example, from Sims 2 DS, is Mayor Honest Jackson. After  waltzes into the hotel, he completely disappears. He still calls your character with requests and romantic options, though, most of which cannot be fulfilled because he's not there.
 * Discussed in Metal Gear Solid Peace Walker. Big Boss rides into the Costa Rican cloud forest on a mule, but encounters enemies who spook the mule and he runs away. While most of your support team is focused on the mission, the younger two, Paz and Chico, are more concerned with what happened to the mule. (It doesn't show up again.)
 * A really bad case of this happen in Scrapland. Through the game, three important city officials are murdered and have their "matrix" (which allow them to be resurrected) stolen, effectively removing them from existence, the goal of the protagonist is to investigate the case and find out who's responsible. However, even after you find and defeat the guy responsible for the plan, what happened to the victims's matrix isn't addressed in any way.
 * For a long time, Ys had this in form of Raba. (or pick your preferred romanization) Appearing in the Very Definitely Final Dungeon of the original game and playing a decently major role in clearing it, the last we see of him he's wounded, but not mortally so, and he could easily have survived or died. He doesn't appear nor is mentioned in Ys II, and Ys III ends up taking place in a distant land. What happened to him was finally addressed in Ys: The Ark Of Napishtim... 5 games and 16 years after his first appearance.
 * What happened to Dogi during V?
 * In Lufia 2 Rise of the Sinistrals, Maxim's childhood friend Tia is the second member of your party. Tia clearly loves Maxim, and follows him on his journey for this reason, despite his cold behaviour towards her. Later, the party meets Selan, who Maxim is clearly interested in. The game appears to be developing a rivalry between Selan and Tia, which one might expect to end with Maxim finally realizing his own true love for Tia, but instead Tia suddenly decides she's had enough and leaves the party, never to be heard from again except in a small scene at the end.
 * The first game did establish he had to end up with Selan eventually, but there were probably much better ways to resolve that than having Tia suddenly decide to vanish from the face of the earth.
 * Maxim was actually just not romantically attracted to Tia at all. Tia's case was more like unrequited love toward Maxim - he just did not want to be bound to a life as a shopkeeper, and he preferred to be with a warrior like himself.
 * In First Encounter Assault Recon, the player character starts out partnered with a man named Jankowski. Very early in the game, Jankowski disappears, but starts appearing to the protagonist as bloody apparitions throughout the rest of the game. It's highly likely that, but no explanation is given for why his apparitions keep following the character, nor is there any conclusive evidence regarding his fate.
 * Word of God confirms he is dead, but they wanted to make it a bit more mysterious, hence why his vital signs keep showing right throughout the game, though with "some kind of interference" Given how powerful Alma is, pretty much nothing is out of the question.
 * Towards the very beginning of Banjo-Tooie, a couple of characters mention how excited they are about "the upcoming kickball game between the Jinjos and the moles": indeed, it's the main reason Jingaling wants to see the Jinjos rescued. The game is never mentioned again.
 * Also, Klungo from the first game. He only appears during the scene where Grunty is shown building the machine she will use to suck the beauty out of Banjo's sister, after which he disappears and is simply never seen, heard, or mentioned again. The only time you ever see him again is if you lose the game, where he actually succeeds in turning Grunty beautiful... at least, until his brief appearance in the ending sequence. He gets an expanded role in all of the other Banjo games, though.
 * In the first level of Halo: Reach, Noble Team comes across a young Hungarian woman named Sára. The game bothers to name her, give a short but personal conversation between her and Jorge, and connect her to moderately important NPC, and then she is never seen or heard from again.
 * Given what happens to Reach, is that really surprising?
 * Dynasty Warriors 4, due to its flexible mission structure, had a few of these:
 * For the forces that battle the Yellow Turbans in the first act (nearly all of them), if you play it in its entirety and then allow Zhang Jiao to escape at Yellow Turban Rebellion, you will not kill him, and you also will not get the Return of the Yellow Turbans special stage, the only other stage he shows up in. You're left with only the assurance that the threat of the Yellow Turbans is over, and Zhang Jiao just quietly fades from history. (I suppose you can assume that he succumbed to disease, since that's what actually happened.)
 * You cannot under any circumstances kill Dong Zhuo at Hu Lao Gate. Meaning that unless you're playing as Lu Bu, the only way to see his demise to get the one of the "Dong Zhuo Lives!" special stages or the "The Symbol of the Mandate" special stage. Therefore, it's very likely you'll finish the entire campaign without ever learning Dong Zhuo's fate. (Similar to Zhang Jiao, you can assume that Lu Bu eventually whacked him.)
 * If you're playing as any force other than Wei, Lu Bu, Dong Zhuo, or the Yellow Turbans, you will face Lu Bu exactly once, at Hu Lao Gate, where it's not possible to kill him. He's never mentioned again. Presumably Wei takes him out, but you only get to see this if you're playing as Wei.
 * Also as Wei, you face Yuan Shao at The Battle of Guan Du, where he'll retreat if things go badly enough. If you didn't meet the requirements for the "The Esteemed Yuan Family" special stage, that's it; he's gone for good and presumably becomes a footnote to history. (THAT, at least, doesn't require much imagination!)
 * Lu Bu, Yuan Shao, and Dong Zhuo have a single battle against each of the Three Kingdoms. Only two of them are required. How Cao Cao, Sun Jian, or Liu Bei knuckles under to your iron rule without a fight is left to your imagination.
 * As Wu, it's possible to get Race For The Nan Territory, where both you and the Shu army battle a total of four Wei generals, after Wei has already been destroyed. Since none of the four die in this battle, it's unclear what becomes of them afterward, or for that matter what the hell they're doing here in the first place.
 * In Lego Batman, a cutscene shows a man preparing to propose to his girlfriend. When he produces the ring, the girl screams and ducks under the table. The man is sad, not realizing that she screamed because Joker and Scarecrow were coming up from behind him in their aircraft. The man is swept up by the planes and is last seen clinging to a steeple. Did he ever get down? Did Batman rescue him? Did his girl say yes?
 * Batman: Arkham Asylum has two goons near the start of the game building a very creepy Joker-themed gate around the entrance to the Visitor Center. Batman can beat them up, and it's in fact encouraged. If you beat them both up, their unconscious bodies disappear eventually (presumably they woke up and left, or their buddies dragged them out of there), leaving the gate unfinished. However, the gate continues to become progressively more finished until the end of the game! There's no indication those two goons are in any way special to the Joker. If those goons are unconscious, and every other goon on the island is busy stalling Batman or otherwise continuing the Joker's transformation of Arkham Island, then who keeps building that gate?
 * In Time Crisis: Project Titan, not only is Kantaris alive, she appears in a couple of cutscenes. She doesn't die, or for that matter fight anyone. And she has not been seen, heard, or mentioned in any Namco game since. (For that matter, does the fact that she's alive mean that Richard Miller failed his special assignment in TC 1?)
 * Syphon Filter: The Omega Strain: What happened to Ivankov?
 * In Puzzle Quest 2 after you gain Rahn the guardsman as a companion (gaining the Besiege spell), you never hear from him again. He has no dialog, unlike your other companions. And when you rescue your companions from Dark Elf Arena, he's not even mentioned.
 * In Odium, while fighting your way through the monster-infested town you meet two random robbers who don't seem to be afraid of all the biomechanical monstrosities roaming around. Your team scolds them, takes their loot (which consists of nothing except for a journal... kind of low ambitions these robbers have) and sends them on their way. You never find out what happened to them afterwards.
 * At the very beginning of Home Front, you are arrested in your home by a KPA colonel named Jeong, who seems like he will be a significant antagonist. He appears exactly one other time in the game, leaves, and is not mentioned again afterward.
 * In the Disgaea: Hour of Darkness game and novel adaptation Laharl’s mother is seen ascending to the afterlife with Vyers, but Vyers has appeared as a cameo in several NIS games afterwards and in later novels comes back as an angel, while Laharl’s poor mother has not been seen or heard from since.
 * Command & Conquer: Tiberium Wars adds a third side to the GDI/Nod conflict with the Scrin Alien Invasion. Whatever campaign you choose, the Scrin discover that Humans Are Warriors and are chased off the planet, planning to return in greater force. They are never heard from again.
 * Legend of Dragoon reveals in the third disc  This is never mentioned again or even touched upon for that matter. Many found it to be a glaring plot hole.
 * Mortal Kombat 9 has a lot of these:
 * is last seen frozen, but not shattered. He just disappears from the scenes, although apparently he did warn.
 * may or may not be dead.
 * Also, Raiden mentions that he sent near the beginning of the MK2 part of the story. It's never mentioned if they succeeded or not.
 * Given how a lot of the info in All There in the Manual, Mortal Kombat suffers from this frequently. For example, it's been brought up in bios that the Sub-Zero bros. were abducted by their father to be taken to China and trained by the Lin Kuei, leaving behind their mother and younger sister in America. The thing is, we never hear of them again, so we don't know of their current status (did they survive Shao Kahn's invasion?). Frost was widely believed to be this long-lost sister of Sub-Zero, but this was disconfirmed by the creators themselves.
 * Every single comic relief baddie from the Pokémon Mystery Dungeon series games. They all only appear in the very beginning, and they all disappear without a trace as the series progresses. Heck, they don't even return after Primal Dialga has finally been taken care of! It's implied that the main reason why they all disappeared very early is because they are actually all afraid of the series' Big Bad,, and that Primal Dialga is the least of their worries.
 * Fear Effect. Hana encounters a frightened old woman in a fishing village. She then leaves the old woman behind and the old woman is not seen or heard from again. Really, Hana should have been given a What the Hell, Hero? scolding for that!
 * In Scaler, what happened to Looger's Henchmen (and woman): Jazz, Rhombus, and Turbine? They appear at the start, make an appearance at the first boss, then turn up as the second boss, are shown in a beaten-up (and alive) state when you beat them... and then are promptly never seen again. What happened? Did they run off? Did they die/Looger dispose of them? Did they come back to our world? We shall never know.
 * One of the numerous subplots brought up in Another Code R is that of Matt's father, who mysteriously disappeared. While all the other subplots and the main plot point are solved, his is dropped in the last two chapters and given only a vague hint as to what happened. The intent was this was going to be a Sequel Hook for a Spin-Off game starring Matt that would answer this question, but became this trope when the company of the series went bankrupt and closed down.
 * Invoked by Silent Hill and Silent Hill 2 with the fates of Cybil and Angela. Cybil isn't mentioned after the first game, and Angela is never seen again after Word of God has stated that they wanted their fates to be open to interperetaion.
 * Soul Calibur 5 really shook up the character list, with almost half the characters from the previous game being removed. Most have retired and passed their skills on to children or successors (Xianghua, Taki), some have just reached the end of their journey and have no reason to continue fighting (Setsuka, Zasalamel), some are dealing with their own stuff (all the Korean characters) and some have just dropped off the face of the earth. Sophita and Cassandra in particular are implied to be dead, and Talim has simply vanished.
 * Mass Effect 3 leaves quite a few missing mice for the Grand Finale. When the Citadel is, there is no mention of what happened to the people on the Citadel, which is quite a few characters. Then there's , which carries quite a few implications itself.
 * Related is where your squad goes during the . They're with you one moment, and don't appear again.
 * Some of these issues are explained in the Codex or other not so central material in the game. At least some of these issues are likely to be addressed in the oncoming ending DLC.
 * In the original version of The Witcher 2: Assassins of Kings the bastard children of King Foltest simply disappear with no mention after the Prologue, in spite of their central role to the events. This is somewhat mended in the Enhanced Edition where, if you pick Roche's path for Act 2, you can receive a side mission dealing with their fate in Act 3. Likewise, Letho's minions Serrit and Auckes disappear from the narration for players choosing Iorveth's path in Act 2.
 * In the Diablo series, aside from the three Prime Evils (Mephisto, Diablo, Baal), there are the four Lesser Evils. Two of them, Andariel and Duriel, are act bosses (Andariel for Act I, Duriel for Act II) in Diablo II. The other two, Azmodan and Belial, have never actually appeared beyond small mentions in the original game's manual and a fleeting mention in in-game lore. They finally make appearances in Diablo III, as the bosses of Acts II (Belial) and III (Azmodan).
 * In Ace Combat 7: Skies Unknown, Trigger's earliest allies like Golem and Mage Squadrons seem to just disappear after he gets transferred to Spare. They are never heard from again, not even in the final climactic battles where everything and the kitchen sink is supposedly getting deployed.
