* While Kazuya's path isn't as extreme as Sephiroth and Ridley's, it's not any better either as we're talking about a BloodKnight seeking any opponent. It gets worse as of ''Tekken 8'' as Kazuya announced the King of Iron Fist Tournament to make fighters prove themselves worthy and if they fail, their country will cease to exist. Imagine that horror inflicted on the Mushroom Kingdom, Hyrule, Tazmily Village, South Island, the Destiny Islands, Kongo Bongo Island, Popstar, the Lylat System, Mute City, Spiral Mountain, Eagleland, Inkadia, etc....

* Why does Joker summon Arsène and not one of his more powerful Personas when facing off against other ''Smash'' fighters? The same reason that the Demi-fiend as the BonusBoss of ''Digital Devil Saga'' uses low-tier Demons against the party: to him, they are simply a mid-tier RandomEncounter. For Joker, using a Persona other than Arsène would skew the battle in his favor to the point of making it ''too easy''. Case in point, Joker using his final Persona, Satanael, allowed him to ''kill a god'', something that only a handful of characters within ''Smash'' can really boast about.

** On the surface, his FinalBoss encounter being a match against Ryu, Ken and another Terry could easily reference ''Capcom vs. SNK'' and be done with it. However, note the theme that plays in that battle: Art of Fighting Ver-230000000.0 from ''Fatal Fury Special'', which plays during the TrueFinalBoss fight against Ryo Sakazaki, SNK's own homage to the ''Street Fighter'' protagonists and one of the first instances of a GuestFighter (albeit as a BonusBoss NPC) shown in a fighting game. The fight not only represents the last time Capcom and SNK formally clashed with each other, but also one of the key moments that led to the creation of ''The King of Fighters'', and by extension, inspired Sakurai to create ''Smash''.

* The battle with Marx is conventionally creepy, but from Kirby's perspective, it might be even ''worse''. [[VideoGame/KirbyStarAllies The last time we saw Marx]], he was an ally of Kirby's who never objected to the pink puffball[[note]]although [[BonusBoss you do fight him in the credits of Heroes in Another Dimension]], but that fight is more like a LegacyBossBattle than an actual conflict, and could even be construed as a mean-spirited, but ultimately harmless prank[[/note]], so to see someone who had seemingly reformed suddenly attack him would likely be nerve-wracking for Kirby. It should be noted, however, that Marx's canonical reason for aiding Kirby in ''Star Allies'' is [[EnemyMine the threat of the Jamba Hearts being dangerous to Marx as well as Kirby]], but the point still stands.

** Simon and Richter represent two different time periods within Nintendo's history; by virtue of being the player character of the first ''VideoGame/CastlevaniaI'', Simon represents the NES, whereas Richter's debut game — ''VideoGame/CastlevaniaRondoOfBlood'' — made its overseas debut on the SNES albeit in the toned down ''VideoGame/CastlevaniaDraculaX''.

* Round #6 of the Mii Fighter Costumes has a connection to Min Min. Ninjara, obviously. ''Tekken'' is a 3D Fighting game. ''Splatoon'' and ''ARMS'' are from the eighth generation of Consoles. ''VideoGame/{{Fallout}}'' has a game titled ''VideoGame/Fallout76'', and Min Min is fighter #76.

* There is also the case of [[VideoGame/{{Undertale}} Sans]], [[VideoGame/{{Fallout}} Vault Boy]], and [[VideoGame/DevilMayCry Dante]] appearing as costumes for the Mii Gunner, alongside [[VideoGame/TheElderScrollsVSkyrim the Dragonborn]] for the Mii Swordfighter, dooming their worlds as well.

** Sonic has the worst luck of all. His appearances in ''WesternAnimation/WreckItRalph'' and ''WesternAnimation/RalphBreaksTheInternet'' wipes out several classic arcade games, as well as the entire Franchise/DisneyAnimatedCanon and the Creator/{{Pixar}} catalogues. His appearance in ''VideoGame/LEGODimensions'' essentially destroys ''Franchise/TheLordOfTheRings'', ''Franchise/HarryPotter'', ''Franchise/DoctorWho'', ''Franchise/BackToTheFuture'', ''WesternAnimation/TheLEGOMovie'', ''Franchise/JurassicPark'', ''WesternAnimation/TheSimpsons'', ''WesternAnimation/AdventureTime'', ''Franchise/{{Ghostbusters}}'', ''[[Film/MissionImpossibleFilmSeries Mission: Impossible]]'', ''Franchise/ThePowerpuffGirls'', ''Series/KnightRider'', ''Film/{{Gremlins}}'', ''Film/TheGoonies'', ''Film/TheWizardOfOz'', ''WesternAnimation/{{Ninjago}}'', ''VideoGame/{{Portal}}'', ''WesternAnimation/LegendsOfChima'', ''Series/TheATeam'', ''Film/ETTheExtraTerrestrial'', ''Series/KnightRider'', ''Film/{{Beetlejuice}}'' and ''Franchise/ScoobyDoo'' and whatever it in turn has crossed over with, amongst others. Or his cameo in ''Film/ReadyPlayerOne'', where all the avatars that appeared in the [[ShoutOut/ReadyPlayerOne2018 OASIS]] had their home universes wiped out as well[[note]]Or possibly not, since those aren't the real characters, but rather avatar skins within a FictionalVideoGame[[/note]]. ''Or'' [[Recap/OKKOLetsBeHeroesS3E10LetsMeetSonic his appearance in]] ''WesternAnimation/OKKOLetsBeHeroes'', which leads to the destruction of ''O.K. K.O.'' itself, ''Webcomic/RPGWorld'', ''WesternAnimation/CaptainPlanet'', and if "[[Recap/OKKOLetsBeHeroesS2E18CrossoverNexus Crossover Nexus]]" is taken into account, ''all'' of Creator/CartoonNetwork's and Creator/HannaBarbera's library, as well as other Creator/WarnerBros animation and acquired shows through crossovers. Sonic has also had brief crossovers with ''VideoGame/AngryBirds'' and ''Hello Kitty'' for ''VideoGame/SonicDash'', the latter of whom had a brief meeting with the original [[Franchise/{{Gundam}} Mobile Suit Gundam]], putting that extended universe at risk.

** Snake's appearance in the series effectively dooms a number of [=PlayStation=] franchises due to Raiden's appearance in ''VideoGame/PlayStationAllStarsBattleRoyale'', wiping out the likes of Kratos (already doomed by way of ''VideoGame/MortalKombat9''), [[VideoGame/{{Uncharted}} Nathan Drake]], [[VideoGame/LittleBigPlanet Sackboy]], Franchise/RatchetAndClank, VideoGame/JakAndDaxter, [[VideoGame/GravityRush Kat]], [[VideoGame/{{Bioshock}} Big Daddy]], [[VideoGame/DMCDevilMayCry reboot Dante]], [[VideoGame/DeadSpace Isaac Clarke]], and a variety of others. Solid Snake and Simon Belmont both showed up in the ''VideoGame/DreamMixTVWorldFighters'' game, which included the likes of other crossover characters like Optimus Prime and Megatron from ''Franchise/{{Transformers}}'', putting them all on Galeem's radar, and then this also puts ''Anime/{{Beyblade Burst}}'' in Galeem's crosshairs due to a crossover between it and Transformers.

*** Making matters worse is the fact that, while no direct connection currently exists within ''Smash Bros.,'' ''Persona's'' parent series ''Franchise/ShinMegamiTensei'' is still in extreme danger of being discovered by Galeem and Dharkon; all it would take is something as simple as a [[SeriesMascot Jack Frost]] spirit or costume getting into the game. Should that ever come to pass, it would mean uber-powerful beings such as YHVH, Lucifer and the Demi-Fiend being in their crosshairs, ending the ForeverWar in that series in the worst way possible and killing ''nigh every mythological being in every religion in the world.'' [[VideoGame/ShinMegamiTenseiV "The God you know is dead"]] indeed. And no, not even [[WakeUpCallBoss Matador's]] Red Capote would get him out of this one.

Not only are her and the Crypton Vocaloids at risk, but Gumi makes a guest appearance in the 3DS version of ''VideoGame/HatsuneMikuProjectDIVA'', dooming the Vocaloids of Internet Co. Ltd. as well (or at least, Gackpoid, Lily, and Cul). Back to Miku, some notable games she cameos in include ''VideoGame/JustDance'', ''VideoGame/Yakuza5'', and ''VideoGame/TheIdolmaster'', which in [[VideoGame/TheIdolmasterCinderellaGirls turn]] [[VideoGame/TheIdolmasterMillionLive affects]] [[VideoGame/TheIdolmasterSideM its]] [[VideoGame/TheIdolmasterShinyColors spinoffs]]. She also appears in ''Anime/ShinkansenHenkeiRoboShinkalion'', which itself crosses over with ''Anime/NeonGenesisEvangelion'' and ''Franchise/{{Godzilla}}'' (with Godzilla then crossing over with several famous movie monsters); as well as appearing in ''Manga/LuckyStar'', which then dooms ''Literature/HaruhiSuzumiya''; ''VideoGame/GrooveCoaster'', dooming the likes of ''Franchise/TouhouProject'', WebAnimation/{{hololive}}, and WebAnimation/KizunaAI; and so on, and so forth...

** Also, let's not forget all the mash-up packs, which puts at risk ''WesternAnimation/DuckTales2017'' (and by extension, [[WesternAnimation/DuckTales1987 the 1987 version]] and ''WesternAnimation/QuackPack'' too, as well as ''WesternAnimation/GoofTroop'' and ''WesternAnimation/DarkwingDuck''), ''Franchise/ToyStory'', ''VideoGame/LittleBigPlanet'', ''Film/PiratesOfTheCaribbean'', and more.

* Mario and Sonic has crossed over VideoGame/MarioAndSonicAtTheOlympicGames several times]], but they happened in real-world locations that hosted the Olympics. Meaning that they most likely put each of the games real-life mascots in danger. There's also a chance that the they ended up endangering real-life athletes; both veteran and newcomers to the games.

** Link had appeared in ''[[VideoGame/SoulSeries SoulCalibur II]]'' for the Nintendo [=GameCube=] version, which dooms the ''Soul'' series characters, but guess who also showed up in that game for the other versions? Heihachi of ''VideoGame/{{Tekken}}'' fame (''Street Fighter'', ''Fatal Fury'', and ''Final Fantasy'' are already in hot water thanks to appearances in Smash but thanks to Negan showing up in ''VideoGame/Tekken7'' alongside these guests, that also means the world of ''Series/TheWalkingDead'' is screwed) and ComicBook/{{Spawn}}. Spawn just recently had a guest appearance in ''VideoGame/MortalKombat11'', and if Sonic didn't already get them in trouble thanks to his varied cameos described below (Kano himself notably showed up in ''WesternAnimation/WreckItRalph'' alongside him), then Link's shared appearance with Spawn guaranteed that the ''Mortal Kombat'' realms would not escape notice. Mortal Kombat itself has also featured the likes of [[VideoGame/GodOfWar Kratos]] (who previously showed up in a Soul game like Link, Heihachi, and Spawn), [[Franchise/ANightmareOnElmStreet Freddy Krueger]], [[Franchise/FridayThe13th Jason Vorhees]], [[Film/TheTexasChainsawMassacre Leatherface]], the Franchise/{{Predator}} ''and'' the [[Franchise/{{Alien}} Xenomorph]] (both of whom already have a number of crossovers under their belts as well), the Franchise/{{Terminator}}, Franchise/RoboCop, and Franchise/{{Rambo}}; that's all of these real world-based universes gone in the blink of an eye. Even without counting the ''Franchise/{{Injustice}}'' universe, [[VideoGame/MortalKombatVsDCUniverse the MK crossover with DC]] also erases Franchise/TheDCU, and accounting for it also deletes ''ComicBook/{{Hellboy}}'', and ''Franchise/TeenageMutantNinjaTurtles'' as well as anything ''they've'' crossed over with, such as ''Franchise/PowerRangers'', ''Franchise/StarTrek'', and ''Franchise/MastersOfTheUniverse''. Link having ties to the ''Soul'' series means that Galeem would also get access to all other guest fighters that showed in these games (from ''Franchise/StarWars'' to ''Franchise/AssassinsCreed'' to ''VideoGame/TheWitcher'', to ''VideoGame/NierAutomata'', and the list can go on). ''Mortal Kombat'' shares a few horror guests with ''VideoGame/DeadByDaylight'', which also drags in ''Franchise/{{Halloween}}'', ''VideoGame/Left4Dead'', ''Franchise/{{Saw}}'', ''Film/{{Scream}}'', ''Franchise/EvilDead'', ''Series/StrangerThings'', and ''Franchise/SilentHill''. And if that isn't enough, Johnny Cage's presence as a GuestFighter in NRS's mobile game ''Wrestling/{{WWE}} Immortals'' also gives Galeem ''another'' entrance into ''the real world''... by way of the aforementioned WWE!

** Mega Man, Ryu, and Pac-Man both have characters appearing in other crossover franchises, such as ''VideoGame/ProjectXZone'', which already puts beloved series such as ''Franchise/AceAttorney'' or ''VideoGame/{{Darkstalkers}}'' or even obscure games like ''VideoGame/ResonanceOfFate'' in danger. The scariest example here is the ''VideoGame/MarvelVsCapcom'' games; the Marvel characters in them, such as ComicBook/SpiderMan, ComicBook/IronMan, and ComicBook/CaptainAmerica, also appear in ''VideoGame/DisneyInfinity'', which effectively wipes out ''Franchise/StarWars'', Creator/{{Pixar}}, and most, if not all Creator/{{Disney}} cartoon characters, which were already in trouble thanks to Sora and the appearances of Cloud and Sephiroth in ''Franchise/KingdomHearts''. And ''both'' the Star Wars and Marvel doors, coupled with a bunch of ''Street Fighter'' guests, ''also'' deletes ''VideoGame/{{Fortnite}}'', which ''in turn'' thanks to a cameo, deletes the ''VideoGame/{{Unreal}}'' universe (already in hot water thanks to [[Franchise/MortalKombat Raiden]]'s appearance in ''VideoGame/UnrealChampionship2TheLiandriConflict'').

* Vault Boy being in? Vault-Tec advertizing themselves in the biggest fighting match out there.

* Many expected the final charater to a character from Creator/SonyInteractiveEntertainment, and in a way they did, but in not the way that expected. Sony was the international publisher of ''Final Fantasy VII'', the European publisher of the first few ''Tekken'' and of the original ''Kingdom Hearts'', as well as the publisher of the Playstation versions of ''Minecraft''. Another thing worth highlighting that many third-party publishers departed from Nintendo to Playstation in the late-90s and 2000s due to both being easier to develop and reach a wider audience. Without the Playstation line of consoles, there would be no ''Metal Gear Solid'', no ''Final Fantasy VII'', no ''Persona'', no ''Castlevania: Symphony of the Night'' and no ''Kingdom Hearts''. Sony is indirectly responsable for bringing to life many of the third-party series represented în the game.

* In Steve's reveal trailer, why is it Mario out of all characters who suffers the AmusingInjuries? Well, consider that Mario has been breaking blocks with his fists for 35 years now. [[SummonBiggerFish Steve is undisputably lord and master of all things blocky]], and his block subjects want their revenge!

** Sephiroth's stage ''does'' have AVALANCHE's ship, but you never see anyone there in person. Sephiroth is a [[HatedByAll loathed monster that only someone as detatched from reality as Professor Hojo would support,]] and Hojo ''certainly'' [[ForScience isn't doing it out of love.]] The DLC trailers make a point of the fighters' friends cheering them on, but Sephiroth doesn't have any. Hell, the fact that you see AVALANCHE's ship flying to prevent his meteor basically means in his own stage, the people in the background are rooting and fighting ''against'' Sephiroth.

* When discussing why Kazuya was chosen and not Heihachi for their Tekken character, Sakurai had stated that Kazuya's devil powers had given him an edge as it allows Kazuya to have more access to abilities more fitting to a platform based fighter that Smash is. But of course that begs the question, why not Jin? He also posesses the same devil gene powers as Kazuya, what gave the father the edge that the son didn't? Quite frankly it comes down to preference, not of Sakurai's preference, but Kazuya and Jin's. Jin rebels against his heritage and despises his devil gene. Hell, the boy enacted World War III in the Tekken universe just to eliminate it. No more is this obvious than the fact that Jin and Devil Jin are always considered separate characters with their own moveset (Devil Jin's moveset is based on Jin from Tekken 3 after Jin unlearned the Mishima style in Tekken 4 to rebel against his bloodline). While he can use it when he needs to, he would rather not have to use it given the choice although by the time of ''Tekken 8'', he's becoming less reluctant. Kazuya on the other hand has no qualms against using it, if he needs that extra edge to defeat his opponent, he won't hesitate to use his devil gene if it gives him the victory he seeks.

** While [[PowerOfHate Ganon]] and [[WouldHurtAChild Galleom's]] track record wouldn't earn them much sympathy (Outside of Ganondorf's transformations [[CameBackWrong usually costing him his sanity]]), Bowser was actively fighting against Galeem, [[AlasPoorVillain and then he's forced to turn into Giga-Bowser to serve him.]] [[BadPeopleAbuseAnimals Rathalos is simply an animal being forced to attack the heroes.]] Dracula probably gets this the worst depending on how you look at is Spirit. It evolves into Soma Cruz, Dracula's reincarnation who refused to be like him. So either you can just miraclously fast-forward Dracula's reincarnation after defeating him, or Galeem or Dharkon didn't go after Dracula (Aside from his second form) to be a boss, they went after Soma, [[MindRape and reverted his own soul back into Dracula.]] And considering the picture used for Soma's Spirit isn't [[SlasherSmile demented, grinning one]] from his game's bad ending, [[KickTheDog it's]] ''[[AndIMustScream very]]'' [[ForcedIntoEvil unlikely he was okay with this.]]

** This might also be why several Spirits keep coming back for Spirit Board events; desperately trying to find homes for themselves and newly-discovered Spirits. And guess what? You’re constantly ''thwarting their efforts'' to find new homes via beating them right back out of their Puppet Fighters and re-collecting them, which means this is either a case of PoorCommunicationKills or TheFarmerAndTheViper. On that note, while it may have been justified due to Galleom at first, using Spirits after World of Light is basically mass ''slavery'', given their previous freedom.

*** Assuming Galeem didn't come for her as well, how did Don Flamenco's girlfirend Carmen react to finding out her boyfriend was blasted and turned into a Spirit?

** As stated above, that fridge horror is alievated. What isn't is what the Spirits we DO see must be thinking about this. People bring up how the Fighters go through intense horror seeing everyone they love ripped away and turned into Spirits, and it's likely they aren't the only ones in horror. Tron Bonne has a spirit, but her brothers and Servbots are nowhere to be seen. Soma Cruz's spirit is gained by evolving Dracula's spirit, implying that Galeem or Dharkon went and ''[[MindRape forcefully reverted his very soul]]'', and his [[SheIsNotMyGirlfriend "friend"]] Mina is absent in Smash.[[note]]And Soma has a chance of [[DespairEventHorizon going crazy when he thinks Mina is killed]] in his game, making things worse.[[/note]] Cream the Rabbit gets a Spirit, [[MissingMom but her mother Vanilla doesn't,]] and her beloved pet Cheese is part of her own Spirit. Baby Mario and Luigi are present, but their unseen parents are nowhere in sight. The Champions of Hyrule's successors don't have Spirits, and two of them are Mipha's little brother and Daruk's descendant. People like Susie, Shadow, and Zero get spirits, but in a sick twist of irony, neither [[DisappearedDad Max Haltmann]], [[MoralityPet Maria]], or [[TheLostLenore Iris]] get ones, while more horrid people like [[TokenEvilTeammate Dark Meta Knight]], [[EvilIsPetty Infinite]], and [[CreateYourOwnVillain Sigma]] do. (Thankfully even worse people like Mephiles and Dr. Weil are also not Spirits) Shantae has an adopted uncle and friends that aren't seen, and like Cloud with Sephiroth, the only familiar spirit to her is [[ArchEnemy Risky]], and unlike Cloud, this wasn’t rectified with updates. Kiddy Kong only shows up when Dixie evolves, and ''he's her baby cousin!'' And that doesn’t even begin to cover the many [[SoleSurvivor Spirits that are the sole representative of their universe]]! Galeem and Dharkon's defeat may free them all, but one has to wonder how many scars they've left on their victims...

** Link had appeared in ''[[VideoGame/SoulSeries SoulCalibur II]]'' for the Nintendo [=GameCube=] version, which dooms the ''Soul'' series characters, but guess who also showed up in that game for the other versions? Heihachi of ''VideoGame/{{Tekken}}'' fame (''Street Fighter'', ''Fatal Fury'', and ''Final Fantasy'' are already in hot water thanks to appearances in Smash but thanks to Negan showing up in ''VideoGame/Tekken7'' alongside these guests, that also means the world of ''Series/TheWalkingDead'' is screwed) and ComicBook/{{Spawn}}. Spawn just recently had a guest appearance in ''VideoGame/MortalKombat11'', and if Sonic didn't already get them in trouble thanks to his varied cameos described below (Kano himself notably showed up in ''WesternAnimation/WreckItRalph'' alongside him), then Link's shared appearance with Spawn guaranteed that the ''Mortal Kombat'' realms would not escape notice. Mortal Kombat itself has also featured the likes of [[VideoGame/GodOfWar Kratos]] (who previously showed up in a Soul game like Link, Heihachi, and Spawn), [[Franchise/ANightmareOnElmStreet Freddy Krueger]], [[Franchise/FridayThe13th Jason Vorhees]], [[Film/TheTexasChainsawMassacre Leatherface]], the Franchise/{{Predator}} ''and'' the [[Franchise/{{Alien}} Xenomorph]] (both of whom already have a number of crossovers under their belts as well), the Franchise/{{Terminator}}, Franchise/RoboCop, and Franchise/{{Rambo}}; that's all of these real world-based universes gone in the blink of an eye. Even unaccounting the ''Franchise/{{Injustice}}'' universe, [[VideoGame/MortalKombatVsDCUniverse the MK crossover with DC]] also erases Franchise/TheDCU, and accounting for it also deletes ''ComicBook/{{Hellboy}}'', and ''Franchise/TeenageMutantNinjaTurtles'' as well as anything ''they've'' crossed over with, such as ''Franchise/PowerRangers'', ''Franchise/StarTrek'', and ''Franchise/MastersOfTheUniverse''. Link having ties to the ''Soul'' series means that Galeem would also get access to all other guest fighters that showed in these games (from ''Franchise/StarWars'' to ''Franchise/AssassinsCreed'' to ''VideoGame/TheWitcher'', to ''VideoGame/NierAutomata'', and the list can go on). ''Mortal Kombat'' shares a few horror guests with ''VideoGame/DeadByDaylight'', which also drags in ''Franchise/{{Halloween}}'', ''VideoGame/Left4Dead'', ''Franchise/{{Saw}}'', ''Film/{{Scream}}'', ''Franchise/EvilDead'', ''Series/StrangerThings'', and ''Franchise/SilentHill''. And if that isn't enough, Johnny Cage's presence as a GuestFighter in NRS's mobile game ''Wrestling/{{WWE}} Immortals'' also gives Galeem ''another'' entrance into ''the real world''... by way of the aforementioned WWE!

** Mario, while probably not as bad as Sonic in this regard, showed up in some old ''[[WesternAnimation/TheSimpsons Simpsons]]'' episodes alongside Donkey Kong, and ''The Simpsons'', which also crossed over with Sonic in the aforementioned ''Lego Dimensions'', is already known for its wide amount of guest appearances whether real-life celebrity or other cartoon and/or video game characters. And even just in terms of official crossovers, that immediately knocks out ''WesternAnimation/{{Futurama}}'', ''WesternAnimation/FamilyGuy'' (and by extension, ''WesternAnimation/AmericanDad'' and ''WesternAnimation/TheClevelandShow''), ''WesternAnimation/BobsBurgers'', ''WesternAnimation/RickAndMorty'', ''Series/{{Cheers}}'' (and by extension, ''Series/{{Frasier}}''), ''Series/TheXFiles'', ''WesternAnimation/{{Archer}}'', ''WesternAnimation/KingOfTheHill'', ''WesternAnimation/SouthPark'', and more. Mametchi's guest appearance in ''VideoGame/MarioKartArcadeGP 2'' puts ''Toys/{{Tamagotchi}}'' at risk, as well. Worst of all, the presence of the Mystery Mushroom in ''VideoGame/SuperMarioMaker'' not only endangers the aformentioned ''Hello Kitty'' and ''Shaun the Sheep'' (and by extension, ''WesternAnimation/WallaceAndGromit'') as well as ''Manga/{{Nisekoi}}'' and ''Anime/OnegaiMyMelody'', but also gives Galeem '''''yet another''''' entrance to the real world via [[Series/RetroGameMaster Shinya Arino]] and Music/{{Babymetal}}.

While many of the Classic Routes are pretty tame for the most part, some of the Classic Routes for the more villainous characters have some disturbing implications or worst possibilites when you look beneath the surface.
