This is when a VideoGame boss isn't teamed up or associated with the BigBad. He's a lone wolf and isn't anyone's lackey. He's a villain on his own.

This is relatively common in {{RPG}}s, where the player party often winds up just running into bosses that just happen to be at the end of caves, attacking a town, guarding {{MacGuffin}}s, etc.

Sometimes overlaps with GiantSpaceFleaFromNowhere, but while the Giant Space Flea From Nowhere comes from out of, well, nowhere, the Lone Wolf Boss is often established into the plot, and sometimes even plays a crucial role in some way, but either has nothing to with the aims of the BigBad, or is outright opposed to them.
!!Examples include:

* King Boom Boo from ''VideoGame/SonicAdventure2''. A ghost is haunting the Death Chamber and harasses Knuckles after he finds the key to Eggman's base. Eggman has his own Egg Golem as a guard, so it wasn't deployed by him.
* The only boss in ''VideoGame/ConkersBadFurDay'' that is related in some way to the [[BigBad Panther King]] is the Experiment; and it's because it and the Tediz were created by Ze Professor so they could ''defeat the Panther King'' (Conker still has to defeat them because they are threatening the otherwise peaceful kingdom).
* ''Franchise/SuperMarioBros'':
** Belome and Punchinello in ''Videogame/SuperMarioRPG''. The game actually has quite a few villains who aren't connected with the main bad guys, but these two are given the least context. There's also Booster, who indirectly causes the game's most extreme example of GiantSpaceFleaFromNowhere. Valentina, like Booster, is also the main villain of a story arc but is in no way affiliated with the BigBad.
** Despite being a Koopa, Jr. Troopa in ''Videogame/PaperMario'' actually isn't aligned with Bowser.
** Most Chapter bosses in PaperMarioTheThousandYearDoor aren't affiliated with the X-Nauts, the main antagonistic force in the game. Hooktail, however, does turn out to have been affiliated with [[spoiler: the game's BiggerBad]]. Most of them, such as Grubba or Cortez, are simply bad guys who found one of the Crystal Stars and are using or hoarding it for entirely selfish reasons. Doopliss is an interesting case since he ''starts out'' as a LoneWolfBoss but then allies himself with the Shadow Sirens after his chapter. Smorg is another odd example in that it was originally intended to have been a creature summoned by Beldam of the Shadow Sirens, but this exposition dialogue was cut in the final version, leaving its origins unambiguous.
** VideoGame/SuperPaperMario has Francis, the third boss.
** Several bosses from ''VideoGame/SuperMarioGalaxy'', such as Major Burrows and Buggaboom, have to be defeated because they're threatening innocent characters for personal reasons, not because Bowser told them to do so.
** The Bubble King and Ghost bosses from ''Videogame/WarioLand 2'', which initially start by capturing the Big Bad (temporarily). Kind of their own antagonists, considering that beating them gets an alternate ending.
** Many examples also exist in the ''Videogame/MarioAndLuigi'' series, like Popple from Superstar Saga, possibly Trunkle from the same game, Bowser in all three games, Durmite/whatever in Bowser's Inside Story, the Tower of Yikk (second giant Bowser boss) in the same game, Mom Piranha and the Piranha Bean in Superstar Saga, Mrs. Thwomp in Partners in Time, and Broque Monsieur in Bowser's Inside Story have no connection to the Big Bad whatsoever, and most have no connection to the storyline at all.
** In VideoGame/MarioAndLuigiDreamTeam, you've got Grobot (which just malfunctioned), Mammoshka (who was just in the way), Mount Pajamaja (who you annoyed in the dream world), Big Massif (who you fight in the dream world to wake up his real world counterpart), Wiggler (who you fight because Popple made you think he was a security guard), Popple (who was just robbing a building at the time), the Zeekeeper, Pi'illodium and quite a few others.
* All of the bosses in ''VideoGame/Sly3HonorAmongThieves'' aside from Dr. M's mutant creatures.
%%* Bull from ''Videogame/TyTheTasmanianTiger''.
* The Ox in the Metropolis level in ''{{Spyro}} 2: Ripto's Rage''.
* Rayquaza from ''VideoGame/SuperSmashBrosBrawl'', though Tabuu does later use him to guard the Great Maze.
* In ''VideoGame/MegaManX6'', Dynamo isn't helping Gate and his Nightmare Investigators, nor X and the maverick hunters; he's just there to gather some nightmare souls (which on this game would be something like Experience points) to make himself stronger.
* Dante plays this role in ''DevilMayCry 4'' (and he is That One Boss to boot). Nero thinks he is the Big Bad at first, since the first thing he does is interrupting a sermon and killing the local pope. He's actually just here to get Yamato back and discover what the Order of the Sword (for which Nero works) is up to. Then Nero discovers that the Not Quite Dead Pope in question is the real Big Bad, so Dante sort of becomes an AloofAlly.
* In the first ''ViewtifulJoe'', Alastor was affiliated with JADOW, but didn't really care for their plans (even after explaining them in meticulous detail by reading the game's script aloud); he (as a NobleDemon Blood Knight) was only concerned with fighting strong opponents like the eponymous hero. In both ''Viewtiful Joe 2'' and ''Double Trouble'', he reappears, unaffiliated with either game's villainous organizations (GEDOW and MADOW) and is again only there to seek a rematch with Joe.
* ''FireEmblem'': Battles against random bandits not affiliated with the story's main villains are ubiquitous, usually early in the game. [[FireEmblemElibe Blazing Blade]] actually somewhat subverts this by having a ''series'' of bandits stretched out over multiple chapters during Lyn's story, thus averting the "lone" aspect of it.
** [[FatBastard Oliver]] in Path of Radiance, a corrupt senator with connections to slave traders, serves as the ArcVillain while the group is in Begnion, but he isn't connected to Daien or [[BigBad Ashnard]] at all. He's actually fought because the leader of Begnion has promised an alliance against Daien on the condition that Ike's group help take him out.
** Validar in ''VideoGame/FireEmblemAwakening'' is a strange case. He's fought while Mad King Gangrel is the current ArcVillain and seems to have no connections to him. However, Validar is actually TheHeavy of the game in reality and Gangrel is just a DiscOneFinalBoss, and while this is obvious to the player from the start, the characters in-game don't know this yet. So serves this role early on before becoming much more important later.
* Most of the enemies in the ''BaldursGate'' games have nothing to do with the main enemy, being interested in you because of who you are or just having their own plans you wander into.
* Your rivals in ''Franchise/{{Pokemon}}''. They're not allied at all with the villainous team that are the main big bads of the game, but they challenge you anyway to test their strength. Sometimes they serve as the TrueFinalBoss after the main villains are dealt with, but not always.
* Cyborg Ninja in ''VideoGame/MetalGearSolid'' is the only boss in the game that isn't a part of Fox Hound. He's a tertiary factor, antagonistic to both sides.
* Papu Papu, the first boss of the first ''VideoGame/CrashBandicoot1996''. Every other boss in the series is either a scientist working with the [[BigBad Neo Cortex]], or an animal Cortex mutated. Papu Papu, on the other hand, is just the leader of a WackyWaysideTribe that Crash stumbles through.
* Mystery G in ''Neo VideoGame/{{Contra}}''. He has no connection to the villains of the game, yet he's only there as a mini-boss in Mission 2 to make sure that Bill Rizer is the ultimate soldier. [[spoiler:He also pulls a HeroicSacrifice halfway through the game, depending on how good your performance was throughout the game.]]
* ''Franchise/TheLegendOfZelda'':
** In ''VideoGame/TheLegendOfZeldaSkywardSword'', Moldarach and Tentalus (both, incidentally, found in Lanayru Desert) are the only two bosses with no connection to Ghirahim.
** Gohdan from ''VideoGame/TheLegendOfZeldaTheWindWaker'' is a creature born of the Gods' need to test the potential hero. As such, he does not appear in the refights at Ganon's Castle.
** Several minibosses in ''VideoGame/TheLegendOfZeldaMajorasMask'', given the nature of the game's villain. Among them, the ancient creatures and peoples of Ikana Canyon stand out, including Captain Skull Keeta, Igos du Ikana, and all of the Garos.
* Benny and Clyde from ''RiverCityRansom'' - they're not affiliated with any of the gangs working for Slick, and it's strongly implied that they fight Alex and Ryan solely because the latter two intruded on the former two's hangout.
* Of the seven sea monsters in ''VideoGame/TheOceanHunter'', five of the seven are explained to have been the creations of the seventh, [[BigBad Rahab]] [[MadGod the sea god]]. The sixth one, [[SandWorm Midgardsorm]], is implied to be a completely unaffiliated party but may have caused more death and destruction than Rahab himself.
* Brady Culture in the first episode of ''VideoGame/SamAndMaxFreelancePolice'' is the only antagonist not working for [[spoiler: Hugh Bliss.]]
* In ''VideoGame/TimeCrisis'' and ''Time Crisis II'', Wild Dog is TheDragon to the games' respective {{Big Bad}}s, but starting in ''3'', he works separately from the FinalBoss to get revenge on the VSSE.

!!Non-Video Game Examples Include:
* ''Literature/{{Harry Potter|and the Chamber of Secrets}}'': Aragog isn't a minion of Voldemort.
* ''Literature/{{Harry Potter|and the Order Of The Phoenix}}'': Dolores Umbridge isn't one of Voldemort's death eaters.
* ''{{Series/Eureka}}'': Most villains aren't affiliated with Beverly Barlowe.
