History Main / UniqueEnemy

* ''VideoGame/StreetsOfRage 2'' - The game has a number of regular {{mooks}} that have names unique to their respective sprite-palette combos. Examples include a Joseph named "Talk" and a Donovan named "U-3". Killing such mooks will net juicy point bonuses (useful for racking up [[EveryTenThousandPoints extends]]).

* ''VideoGame/{{Bug}}'': While the ice fly enemies in [[SlippySlideyIceWorld Bur-r-ubs]] aren't unique (there's a chasm where a few flying ones need to be {{Goomba Springboard}}ed on), there's only one in the entire game that stands on a platform and uses icy breath on the area near it. It's also the only enemy in the game that can give Bug a "freeze" hurt animation.

* ''VideoGame/SpecOpsTheLine'' has only 7 Bayonet Runners out of hundreds of mooks. There are a low number of heavies - seven foot soldiers with massive armor and a BFG. There is only one of them who is a [[spoiler:hallucination of your deceased squadmate]], and he's incredibly challenging to beat. Lose to him, and you [[spoiler:flash back a bit to find he's replaced by a normal heavy, suggesting he was a hallucination]]. One other unique, very difficult heavy seemingly teleports about a room and flashes in and out of existence in a room full of mannequins. This guy has a very good chance of causing a Game Over, and his strange power seems to be a result of [[spoiler:the protagonist's frayed sanity causing him to hallucinate]].

** ''VideoGame/Pikmin4'': The Puffstool and its posionous PaletteSwap the Toxstool only make one appearance each, with the former being in the Primordial Thicket and the latter being in the first floor of the [[VeryDefinitelyFinalDungeon Cavern for a King]]. Neither of them are in a Dandori stage, either.

** ''VideoGame/CrashBandicoot4ItsAboutTime'' has only a single hostile boar and two crabs, both encountered within the first two minutes of the first level, "A Rude Awakening". Their presence serves as a throwback to the original ''Crash'', contributing to the NostalgiaLevel feel of this opening section - it's only after getting past them that the level starts changing things up from the original N. Sanity Beach setting. It's also worth noting that the crabs are the ''only'' enemies in the game that have a unique death animation for Crash only - if Coco dies to the crabs she just gets the generic angel death animation.
*** In the same game, there's also only one non-boss enemy that provides ''two'' death animations: the ball-and-chain-wielding zombies in the levels "Snow Way Out" and "Stay Frosty". One if they hit you from a distance, and another if you run into them up close.

** Guard dogs tend to fill this role in ''VideoGame/CallOfDuty'' games, thanks in part to their DemonicSpiders status when they're ''not'' limited to one or two levels.
*** There is exactly one guard dog in ''Videogame/CallOfDutyBlackOps''. It appears in the beginning of "WMD".
*** In the previous ''Call of Duty: World at War'', you encounter only about three guard dogs in the entire game, all of which you fight exclusively in "Vendetta".
*** The same more or less applies to ''Call of Duty: VideoGame/ModernWarfare 3''. Guard dogs are exclusive to the level "Eye of the Storm" and its Spec Ops variation "Resistance Movement", while the similar hyenas only appear in "Back on the Grid" and its variation "Fatal Extraction".
** In ''Black Ops'', "Heavies" make an appearance in the campaign and have the unique trait of having roughly triple the health of regular enemies, but make just two appearances despite their potential to shake encounters up. In "Vorkuta" they wield the KS-23 and perpetually spawn while you are trying to breach the armory. In "Redemption" a pair of them wielding RPK's are among the final enemies you encounter in the entire game.
** ''VideoGame/CallOfDutyBlackOpsIII''[='=]s "Demon Within" level marks the only campaign appearances of Nazis, Dire Wolves, and then [[VideoGame/NaziZombies zombies]].
** In ''VideoGame/CallOfDuty4ModernWarfare'', an Ultranationalist in "Crew Expendable" carries a Desert Eagle, the only one you can find in campaign (he drops two of them, due to a bug). Furthermore, an Ultranationalist in "Game Over" carries an M60E4.

** ''[[VideoGame/MedalOfHonorFrontline Frontline]]'' has an angry chef who throws knifes at you (and it's implied it's the ''same'' chef judging by his evolving AmusingInjuries every time you meet him).

*** A Black Guard with an MP40 can also be found in the same mission.

* Many enemies in ''VideoGame/MrGimmick'' are encountered only once.

* ''VideoGame/SpiderManPS4'' has the corrupt NYPD bomb squad in the prologue, who serve as an introduction to {{Shield Bearing Mook}}s. They're the sole instance of enemy police officers in the entire game.

->''One. Just one. One red Snifit. In [[VideoGame/SuperMarioBros2 the]] '''[[VideoGame/SuperMarioBros2 entire game]]''', this is the only red Snifit. Seriously. What the hell?''

->''One. Just one. One red Snifit. In the '''entire game''', this is the only red Snifit. Seriously. What the hell?''

* In the [[BrutalBonusLevel Special Stage]] of ''[[VideoGame/{{Parodius}} Gokujou Parodius]]'', just before the [[OptionalBoss Robot Penguin]], you will encounter an enemy called the "16-Bit Block," (literally just a giant white block that says "16 Bit" on it) which has 65536 hit points [[InvincibleMinorMinion and will scroll off the screen before you can do any significant damage]].

** When the whip copy ability was first introduced in the series, it was always given by Whippy, a catlike WaddlingHead with a whip-tail. In ''VideoGame/KirbyPlanetRobobot'', however, Whippy appears only once in one of the game's last EX stages. Whip is somewhat rare to find in ''Planet Robobot'' (it only starts showing up in the second half of the game) and its designated enemy is the newly introduced Wester, so the single Whippy comes across as a secret nod to the previous two games where it was more common.

*** "http://deckers.die" has you fight Cyber-Deckers, who use Cyber Blasters. The same mission also contains the virtual variant of the Decker specialist, who functions the same as her real-world counterpart, but uses Cyber Blasters and a unique virtual variant of the Shock Hammer.

* ''VideoGame/StarWarsBattlefrontII'' occasionally has enemies who are only fought in certain campaign missions.
** Several Acklay inexplecably show up on Felucia to attack the Clones.
** Temple guards fight alongside the Jedi during the Jedi Temple raid.
** Just like in the first game's campaign, the Theed mission is the only time the Naboo Security Forces appear.
** The Anti-Imperial Clone army on Kamino has Jet Troopers who wield blaster rifles instead of the EMP launchers that the playable ones have, as well as ARC Troopers with chainguns.
** Outside of the campaign, Gamorrean Guards are only present in Jabba's Palace and are not featured in the hunt gamemode unlike most of the other native units.

* ''VideoGame/JustCause2'' has a few rare enemies that only spawn in scripted missions:
** The ''Mile High Club'' mission spawns armed male and female strippers who shoot at Rico.
** The Seabreeze Logging company spawns armed logging workers who don't appear anywhere else in the game.
** The mission "Information Highway" contains the only Police officer seen in the entire game.
* ''VideoGame/RedFactionGuerrilla'' has the enemy [=VIPs=] in the mission "Death By Committee". They use the same models as civilians, but they are on the EDF's side.

* In ''[[VideoGame/DeadlyRoomsOfDeath DROD: King Dugan's Dungeon]]'', spiders appear only in Level 10. In the sequel, ''Journey to Rooted Hold'', they appear only in two rooms.

*** The terrorists in the first mission, "Zero Saints Thirty". They also use the Mercenary LMG costume of the Assault Rifle, making them the only NPCs in the game to use a non-default weapon costume.

*** "Gangstas In Space" has the space Luchadores, who fight exactly like the standard ones.

*** The ''Breakthrough'' ExpansionpPack has a total of one [=AB41=] Armored Car fought throughout the entirety of the game, specifically during the first level set in Sicily. The second one encountered is actually driven and used by Baker to blow up a German railway gun at the bottom of a slope.
