Unique Enemy / Super Mario Bros.

Super Mario Bros. has quite a number of Unique Enemies:

• Super Mario Bros.:
  • World 5-4 has a single Firebar twice as long as every other Firebar in the game. Its sole purpose seems to be to prevent the player from easily getting the only power-up in the level.
  • World 7-3 is the only level with flying green Koopa Paratroopas (though the bouncing ones are found in other levels, such as 8-2).
• Super Mario Bros. 2:
  • Most Snifits in the game are grey or green, and stand still without moving from their places, or pink, and move about but turn around when they hit a ledge (in Super Mario All-Stars, the ones that move around are blue and the stationary ones are grey). A single Red Snifit shows up in one room of 3-3, and will jump down at ledges to pursue the player. It was the former Trope Namer. Despite this, most subsequent appearances of Snifits in Mario games and media have had them be red by default.
  • Only present in Super Mario Advance is a blue pointy enemy referred to as a "bouncing blade", found in a vase in World 5-2. It stays completely still, bobbing up and down, and can only be defeated with a starman.
• Super Mario Bros. 3:
  • The Missile Bill, which has a homing ability, only appears in World 4-5.
  • The shoe-wearing Goombas (along with Goomba's Shoe itself) appear only in World 5-3.
  • The game also has the Spiny Cheep-Cheep and a lone fire-breathing Nipper (both found in World 7, 7-4 and 7-8 respectively).
  • The Para-Beetles are only found in one level of World 5: 5-6, on the sky portion of the map. It seems they were planned to be in more levels, according to the screenshot of a deleted level on the box. There's also a green version in some of the Dummied Out levels.
  • The Fire Brothers are only encountered in a secret part of the World 2 map, carrying the third Warp Whistle, and as a solitary individual in one of the Hand Trap stages in World 8.
  • The Angry Sun in an unnumbered stage of World 2 and World 8-2. The former also has a whirlwind-like obstacle that shows up nowhere else.
• Super Mario World:
  • Forest of Illusion 4 is the only level with Fishin' Lakitu, who taunts you with a 1-up mushroom on a fishing pole. If you grab the 1-up, the Lakitu will start throwing Spiny Eggs. Despite its rarity, the fishing pole has since become an Iconic Item for Lakitus in spinoff games, most notably Mario Kart.
  • There's also the Fishin' Boo, a ghost Lakitu that follows Mario with a blue flame on a fishing rod. It only appears for a short while in the first room of the Chocolate Island Ghost House. The same stage also has a few Boos that turn into solid blocks when Mario looks at them.
  • The Torpedo Teds of Soda Lake. It's a hidden level too (which leads to Star Road), and in fact one of the most well-hidden levels in the game, so it's likely the first time you'll see them is in the ending roll call.
  • Bowser's Castle has three examples: The Ninji enemy from Super Mario Bros. 2, which shows up in the last hallway. There are also Mechakoopas seen in one of the selectable paths (door 3), in the aforementioned last hallway, and during the final battle. Finally, there are three gold-colored Bowser statues in one of the selectable paths (door 7); unlike the common stone statue which shoots fireballs at Mario or Luigi, these jump towards them and cannot be stepped onto.
  • The offscreen, random Bullet Bill generators that are in a few of the later athletic levels of the original Super Mario Bros. return in Super Mario World. There is actually a diagonal variant of the generated bullets in this game, but it appears only in one sublevel of Cheese Bridge Area. Said sublevel is not only a mere 4 screens long but contains no items of any kind, so unless you take an exceedingly long time getting across the moving platforms, it's not terribly unlikely that you'll see the bullets fire once the first time playing the game and then never again. In fact, there are three different variants of these generators in this game: the aforementioned, the basic horizontal ones, and one that spawns two horizontal and two vertical bullets. All of them are rare and rarely seen; the other two appear only in Vanilla Dome 4, the horizontal one in the first half of the level and the multi-directional one in the second half, and a quick player can actually bypass the latter entirely (making use of the bonus room to skip part of the level).
  • The cannons from which the Bullet Bills come from, which is in many levels in SMB1 and SMB3, only appear in the seventh Special World level, Outrageous, and the first room of Sunken Ghost Ship, which is a deliberate throwback to the airships from SMB3.
  • Also from SMB1, the flying Cheep-Cheep generator is MUCH more aggressive in this game... but it is only ever seen in about seven screens of the fourth Special World level, Awesome, and most players will probably have taken the Super Star to deal with them easier anyway.
  • Outrageous also features the hopping flame enemies, called Bound Fire. That's their only appearance in the entire Mario series.
  • Dry Bones appears in the majority of the castle and fortress stages, either staying on ledges or throwing bones (Valley Fortress has both types). However, the Dry Bones in Bowser's Castle both stay on ledges and throw bones, which is unique to that level (in fact, the enemy's code even checks for that specific level number). And the only Dry Bones in Bowser's Castle are two in the room for door 6.
  • Grinders, the rotating circular sawblades, show up in a few different castle and fortress stages, but the only place they are found without accompanying line guides is the second room of Forest Fortress.
  • The small fireballs spat by Bowser statues also appear without the statues, by themselves in the level and spawned from a generator, only in the first room of Chocolate Fortress. Presumably in homage to the castle levels in SMB1 and Bowser's Castle in SMB3.
  • The Urchins appear only in Forest of Illusion 2 (and the ones that move a fixed distance are particularly rare, there being only three of them in the level).
  • There is only one multi-jumping Cheep Cheep in the game, at the end of Yoshi's Island 4. There is also only one upside-down chainsaw, near the end of Cheese Bridge Area, despite the rightside-up variant being more common.
  • The Para-Bomb and Para-Goomba generators each appear in only one level, Vanilla Secret 2 and Donut Plains 4 respectively.
• Super Mario World 2: Yoshi's Island:
  • This game provides many examples that appear in only one castle or fortress stage. Georgette Jelly is exclusive to 5-4 as are the slugs that the level's boss is formed from, Lemon Drops are only ever seen in one room of 3-4 (aside from the one Lemon Drop that Kamek enchants to create Salvo the Slime), Aqua Lakitu is found only in a side path of 3-8, Piro Dangle is found only in one optional room in 1-4, a secret room in 2-4 contains the only Blindfold Boo in the game, and the 32x32 variant of the Milde enemy is never seen outside of a secret room in 4-8 and the 4-4 boss battle. Grim Leecher is found only in a couple places in Extra 4. Yoshi's Story is similar, with enemies like Blindfold Boo and Barbecue Boy only appearing in one stage. Because all bosses in Yoshi's Island are of the Giant Mook variety (after a Make My Monster Grow sequence), many are based on enemies that appear in the boss's level (long enough to "establish" them as monsters) and nowhere else.
  • 3-7 has the Lunge Fish, a large fish that leaps out of the water to try and swallow Yoshi whole. They only appear at the very end of the level, and nowhere else in the game. The same level also has Barney Bubble, a strange purple creature that blows bubbles when you stomp on it. Only two appear near the end of the level, just before the Lunge Fish section. Barney Bubbles appear again in Secret 6 of the GBA version.
  • As an Easter Egg, killing the one and only Chain Chomp in 5-4 (which requires the use of an item, since he can't be eaten, stomped, or killed with an egg) reveals a hidden message block. 5-4 also features the only appearance of Muddy Buddy (who is actually a helpful creature), and in an optional room at that. Muddy Buddy appears again in Secret 2 in the GBA version.
  • Goombas, despite their prominence throughout the rest of the Mario series, are only seen here in 4-1. The same level also gives us the Flutter enemies, which are continually generated, but only found in the last section of the level before the goal. Flutters appear one more time in the GBA version in Secret 6.
  • A lone yellow Bullet Bill blaster, which swivels and whose bullets bounce off walls, appears in 5-8. The GBA version, again, adds one other yellow Bullet Bill blaster in Secret 4.
  • Also on the subject of the GBA version, Secret 6 has red Bullet Bill blasters, whose bullets will home in on Yoshi while biting their teeth and disappear after a while. Although unlike the yellow ones, there are multiple red blasters in the level they appear in. The red variant is fully coded in the SNES version, but it never shows up at all in that one.
  • Gargantua Blargg only appears once in both Yoshi's Island and Yoshi's Island DS (not counting the taller Crusher Blarggs from the latter) but three appear in two levels in Yoshi's New Island. Similarly, Hefty Goonie only appeared once in the original, but it appears in at least three levels in Yoshi's New Island.
  • Only two Spikes appear in the game, both in the first room of 5-1. A third appears in the GBA remake, in the first section of Secret 6.
  • In Yoshi's New Island, it's easier to list the enemies that aren't unique to one stage. For example, outside of a single hiding Bandit in 5-3, you'll only encounter them in 6-2. There is also only one Whirly Fly Guy tucked in at the end of 1-3, Woozy Guys and Caged Ghosts only appear in 3-8 (the former being spat out by the latter), and the flying Skeleton Goonies only appear in an optional hot air balloon section in 6-7 and outside Bowser's Castle in 6-8.
• Super Mario Land has a lot of bizarre enemies that only appear in a single level, including the flies that rain arrows down on you in 1-2, the aliens that shoot their heads in 2-2, and the jiangshi in 4-1 that come back to life after being stomped, like a faster reviving Dry Bones. But the purest example of this is the final level: 4-3. Just before you reach the Final Boss room, a pair of human fists punch out from the pipes (in the second quest, there's a third one). It's saying something that in a game that's already full of bizarre enemies, they are the most bizarre of all. They reappear in Super Mario Land 2: Six Golden Coins, once again being exclusive to the final level and appearing only three times, but this time being modeled after Wario's fists.
• Super Mario Land 2: 6 Golden Coins has Number 48, the little star-throwing spaceship from Space Zone 1, and Kurokyura, the vampire from Pumpkin Zone 2, who each only appear once in the entire game. This is in addition to a massive roster of enemies who only appear a couple of times and only in a single level like Aqua Goombas, the Hopping Brooms, the Masked Ghouls, and the Beach-ball Bears. Really it would be easier to list the enemies that don't have only a couple of appearances in the game: Goombas, Koopa Troopas, Piranha Plants and Para-Goombas.
• Super Mario 64:
  • In Cool Cool Mountain, on the longest bridge, there are two Mr. Blizzard enemies who behave differently from the ones elsewhere in the game, as they hop back and forth across a bridge rather than pivoting in place and throwing snowballs at you. Also, since they cannot be run around, they cannot be defeated. In the remake, there are other ways to defeat Mr. Blizzards that will work on them.
  • This platforming adventure includes a Mad Piano in Big Boo's Haunt that attacks when you get near it and can't be killed.
  • Hazy Maze Cave is the only level to contain Swoops.
  • Bob-omb Battlefield has a solitary Chain Chomp which you must set free to get a star.
  • Bubbas (large fish that will eat you) are only found in Tiny Huge Island, on the Huge Side.
  • The Tox Boxes, Pokeys, Grindels/Spindels, and Klepto the Condor only appear in Shifting Sand Land.
  • Two Moneybags enemies appear in Snowman's Land and nowhere else.
  • The only Manta Ray, Sushi, and two Cheep Cheeps in the entire game appear in Dire Dire Docks at the very beginning, near the whirlpool.
  • Unagi the Eel is found exclusively on Jolly Roger's Bay, and there's only one.
  • There's a single Bill Blaster in the entire game, in Whomp's Fortress. And it only shows up from the second mission onwards.
  • Bomps, wall enemies that push Mario, are found exclusively in Whomp's Fortress. You can even skip them altogether.
  • The Fwoosh, a wind-blowing cloud, is exclusively found in a specific cliffside in Tall, Tall Mountain (near the entrance to the secret slide). Some people might not even notice its existence if they keep following the mountain path fast enough.
• Super Mario Sunshine:
  • Hatopops are green parrot-like birds that are only found in Noki Bay. They push Mario out of alcoves, which makes them rather annoying to deal with.
  • Chain Chomplets, the smaller puppy variants of Chain Chomps, are exclusively found in the first mission of Pianta Village. An actual Chain Chomp is found in the fourth mission of said level and only there.
  • The fifth mission of Pinna Park is home to the Green Electrokoopa, an enemy that makes its only appearance in this level. Defeating it is the main goal of the mission.
  • Despite being recurring enemies in other Mario titles, Boos are found exclusively within Hotel Delfino at Sirena Beach.
• Super Mario Galaxy:
  • The lone Big Goomba, which is too big to jump on.
  • Galaxy also features only two giant jellyfish enemies in the whole game, as well as only two Spiny Cheep Cheeps. Only one of each appeared in Super Mario Galaxy 2.
  • There are also only two giant Pokey enemies that you have to defeat by spinning coconuts at them, as well as a single Red Pokey in the desert level. They don't show up at all in the sequel.
  • Boo's Boneyard Galaxy houses the only four Banekiti in the entire series, an enemy type so obscure it doesn't even have an official English name.
  • Jump Guarder is a Topman-variant that can spawn Topminis, but it only shows up one time.
  • While Chain Chomps show up very frequently in the Galaxy games, their smaller baby variants only show up on a single planet in Dreadnought Galaxy.
  • While their smaller cousins show up in several missions throughout the game, there are only two Banzai Bill Cannons, both of which are in the last segment leading up to the final boss battle.
  • The Sentry Garage, a Mook Maker that spawns Topminis and can be used as a spring, only appears at the top of the tower in Buoy Base Galaxy.
• In Super Mario Galaxy 2, there are quite a few examples in the game. Among others, there is only one Spiky Piranha Plant at the end of Sky Station Galaxy's second stage, a single Jammyfish in the middle of Cosmic Cove's second mission, Cluckbooms, Pokey Sprouts, and Rhomps only appear in the first mission of Slipsand Galaxy, and Kleptoads only appear in a Hungry Luma planet in Hightail Falls Galaxy. Magmaws only appear in the Melty Monster Galaxy on one planet. While Spring Vaults showed up a couple of times in the first game, there's only one here, in the Space Storm Galaxy.
• New Super Mario Bros. series:
  • New Super Mario Bros. (DS):
    • Sushis, the shark enemy, only appear in level 1-A.
    • World 3-Castle is the only level that features Whomps. Furthermore, only one of the Whomps is the kind that walks around, while the rest of them are stationary.
    • Scuttlebugs have two varieties: the type which hangs from a web off of the top of the screen appears mostly in 4-1 with a single one appearing at the end of 8-4, while the ones which drop from the web to chase you only appear in 8-4.
    • The Balloon Boo, which grows when looked at and shrinks while chasing you when not in your sight, only appears in 4-Ghost House.
    • Snow Spikes, a snow-themed variant of the Spike (the enemies from SMB3 and beyond who barf up spike balls and throw them) only appear in 5-1. However, they do make a few more appearances in the Paper Mario series.
    • The Snailicorn, an enemy that must be defeated by knocking them off the stage, appear in just two levels, 5-3 and 5-B. Eight of them exist in total, and this is also their only appearance in any Mario game period.
    • A puffy-lipped Bob-omb-like enemy called the Kab-omb only appears in World 8-8. Bizarrely, it makes a reappearance in Mario Golf: World Tour game as an item.
    • So far, there has only been one blue-shelled Koopa in the entire New series, and it's not even in a main level: It's found in the ice-themed versus stage of the first game. Hitting it once will turn it into a Blue Shell power-up for the player.
  • Multiple games:
    • The King Bill appears in only one level each in New Super Mario Bros. Wii and New Super Mario Bros. U (9-8 and 5-Secret, respectively).
    • The Fliprus appears in two levels of New Super Mario Bros. U and New Super Luigi U; Frosted Glacier Secret (Fliprus Lake) and World Coin-7 (a multiplayer only level) in the former, and Frosted Glacier Secret (Fliprus Floes) and Superstar Road 4 (Hammerswing Hangout) in the latter.
    • In NSMB1, the only level where Sledge Bros. show up is 8-7. In New Super Mario Bros. 2, a single Sledge Bro is in the main game, in level 2-2 (though a few appear in Downloadable Content Coin Rush level packs). Three Sledge Bros. are in New Super Mario Bros. U, all of them in the World 7 castle. In New Super Luigi U, they only appear in All Aboard!.
    • Boomerang Bros. only appear in one level in NSMBW (World 2-1). They also only appear once in NSMBU (Bouncy Cloud Boomerangs, aka World 7-4) and in NSLU's equivalent level (Above the Bouncy Clouds) as well as All Aboard! (Soda Jungle-Airship).
    • Fire Bros., like Sledge Bros. only show up in 8-7 of the DS game, and there are also only two of them. In 2, they only appear in 6-3 and stage 2 of Coin Challenge Pack B.
    • The once-common Flame Chomp has become this in New Super Mario Bros. U. It shows up in one level in the final world, and is truly unique in that aspect as there really is only one in the whole game. New Super Luigi U also only contains them in one level (Flame Chomp Ferris Wheel, Meringue Clouds-5), but has them in a larger quantity.
    • Foos only appear in one level each in NSMBW (World 7-5), NSMBU (World 7-6, Snaking Above Mist Valley), and NSLU (World 7-6, Three-Headed Snake Block).
    • Magmaarghs only appear in NSMBU in the boss fight against Iggy Koopa in both NSMBU and NSLU.
    • Magmaws are only in Magma-River Cruise in NSMBU, and in Magmaw River Cruise and The Final Battle in NSLU.
    • Sumo Bros. only appear in one level in NSMBU (Screwtop Tower, aka World 6-Tower 2). They also appear in NSLU's equivalent level (Sumo Bro's Spinning Tower), but at least get another level dedicated to them (Sumo Bro Bridge, Soda Jungle-6).
• Super Mario 3D World has a few:
  • The Charvaargh shows up only in the final section of 7-7.
  • The Fuzzler is exclusive to 3-7.
  • Cheep-Cheeps and Porcupuffers only appear in 3-5. This is rather surprising, as Cheep Cheeps are relatively common in the other games they're in.
• Super Mario RPG:
  • Lakitus appear in a few early areas of the game to toss out enemies, but most of the time they're out of reach. The only time where Mario can touch one to battle is on the first screen of Booster Pass. A group of three appear in a (potentially) optional battle hallway in Bowser's Keep, but since that's the penultimate dungeon, they can be wiped out with a single area attack.
  • The Apprentice is a variant of the Spookum enemies found in Booster Tower (same color, different stats and spells), and only shows up in a secret path of Booster Pass. It gets unique dialogue when you encounter it, though it isn't quite an Optional Boss since it lacks boss music, can be dodged completely while still getting the item boxes it guards, respawns after leaving and returning to the area, and is extremely weak. However, dying to it doesn't cause a game over and instead leads to a cutscene where the Apprentice runs off to get promoted into a Snifit by Booster; returning to the area afterwards spawns another Apprentice waiting to be promoted, and this can be repeated for up to five Apprentices. Each one you lose to appears in Booster Tower as an NPC.
  • The four Chest Monster Bosses In Mook Clothing can only be encountered in one non-respawning item box each, though Box Boy can also appear by failing the limited slot chest microgames in Bean Valley, while Chester is infinitely refightable by going down one of the enemy hallways in Bowser's Keep (since it doesn't have an item box). Some of them spawn enemies that don't appear anywhere else as well.
  • A Blooper Nanny shows up in one room deep in the Sunken Ship. It's only unique on the field and not in battle, as touching it or its Blooper Babies starts a battle with standard Bloopers.
• Paper Mario 64:
  • Bullet Bills can only be fought once at the very end of the Koopa Bros. Fortress. Once you beat the Bill Blasters that shoot them, they're impossible to fight again besides a golden variation found at Bowser's Castle.
  • The Stone Chomps in Dry Dry Ruins. They are fought in groups of two and they only appear three times, directly after Mario collects the Pyramid, Diamond, and Lunar Stone.
  • The weird flying jellyfish-like creatures (named only in a strategy guide as "Sentinels") that patrol Tubba Blubba's Castle. They can't be fought, and only act as Mook Bouncers. The castle gets emptied of enemies after Chapter 3, removing the Sentinels as well.
  • The green Monty Mole recolors (named the same as the ones from Mt. Rugged) appear on a single screen of Flower Fields as part of Chapter 6's storyline, and don't respawn after being defeated.
  • The Amazy Dayzee is found only in one spot in the Flower Fields and is randomly generated to be there about 10% of the time. The rest of the time, it's a normal Crayzee Dayzee. It is also ridiculously strong and likes to run away as soon as possible, but if Mario can defeat it before it runs or he dies, the Amazy Dayzee will provide a mountain of experience points.
  • Boss-summoned enemies are exclusive to their fights, like Tutankoopa's Chain Chomp, Lava Piranha's Petit Piranhas, the Crystal King's Crystal Bits and General Guy's Stilt Guys and Shy Stacks.
• Paper Mario: The Thousand-Year Door:
  • A group of two Bald Clefts appear in one scipted fight of Petal Meadows, serving as a Noob Bridge (their defense is too high for normal attacks, requiring an item, Power Smash, or superguarding). Bristles are introduced in the same way, but are also part of the Glitz Pit.
  • There is a type of Yux, the X-Yux, that you only run into once, guarding Grodus's office; it is by itself in the room and doesn't respawn. Two more attack you if you fail the quiz in the X-Naut Fortress.
  • Many of the Glitz Pit teams feature one-time enemies: KP Koopas and KP Paratroopas (KP Koopas), Big Bandits (Hand-It-Overs), Hyper Bald Clefts (Punk Rocks), Red Spike Tops (Tiny Spinies), Shady Paratroopas (Shellshockers), the three alternate Magikoopa colors (Magikoopa Masters), and Boomerang Bro and Fire Bro (Hamma, Bamma, and Flare). All of these are fought in tournament bouts and don't drop items.
  • Most of the toughest versions of enemies are exclusive to the Pit of 100 Trials.
• Super Paper Mario:
  • A line of five Thwomps appear in Chapter 1-2 as a demonstration of 3D flipping and don't show up anywhere else. Their cousins the Spiky Tromps only appear in 1-4 (while the similar Spiny Tromps at least appear in two levels).
  • Frackles and Wrackles only appear as ammo in the fights with Fracktail and Wracktail respectively.
  • Chapter 2-2 features two Gnips and one Gnaw, Merlee's invincible pets that throw the current character out of her mansion if they grab them. Chapter 2-4, Merlee's Basement, features one Atomic Boo, heavily downgraded from its Optional Boss fight in The Thousand-Year Door.
  • Chapter 3 has many level-exclusive enemies, none of which have Dark versions in Flopside's Pit of 100 Trials later on. 3-1 contains two Bill Blasters, guarding Bowser's Castle at the very end, and one respawns in revists to the level; the same level also includes the game's only four Toopa Strikers (variants of the Koopa Striker enemy that can kick shells back and forth between themselves), as well as a special encounter with a giant 8-bit Mega Koopa. 3-2, the Tile Pool, is the game's sole fully underwater level and is the only place Bittacudas are fought (other water enemies appear during a segment of Chapter 8-3). The Meowmaid enemy types are frequent in Chapter 3-4, Fort Francis, but never show up outside of it (except Meowbombs if you refight Francis in Chapter 8-2).
  • Most of the space enemies are justifiably never seen outside of Chapter 4-1 and 4-3. The Eeligons/Hooligons are, however it's implied they could basically live anywhere.
  • There are five different types of Cursya (discounting Dark variants) and most of them appear several times, but there are just two Back Cursyas in the whole game, one in Chapter 3-1 and another in Chapter 5-1, and they have no Dark version. It's for the best, since the curse they inflict upon contact sends you back to Flipside.
  • 7-1, the first Underwhere level, is the only stage in the game with Frost Piranhas and Lava Bubbles, which were more common in the earlier Paper Mario games. They don't appear in either Pit of 100 Trials.
  • The Flopside Pit of 100 Trials includes "Dark" variants of most enemies in the game that are exclusive to the dungeon. A prominent one is Dark Headbonk Goombas, which only appear on a very late floor and are a tougher version of an enemy that shows up on one floor of Flipside's Pit of 100 Trials and nowhere else (Squoinkers are also exclusive to Flipside's Pit, but they appear on multiple floors).
  • There's only one Barribad, which is found in the Whoa Zone. It has a Dark variant, which again can only be seen once.
• Paper Mario: Sticker Star:
  • A single Lakitu appears in Whammino Mountain and tosses endless Spinies at you as you walk along a path. It can't be fought, but it can be defeated with a precise jump using the nearby Starman. Oddly, it does have a list of sprites for being damaged normally, meaning it was likely intended to be battled at one point.
  • The 5-Fold Paragoomba is only encountered once in the game, pestering the Traveling Toad in World 2, and even then you don't have to fight it as you can spend coins to skip it entirely.
  • While Sombrero Guys appear a few times in World 2, there's his partners, the Maraca Guy and Accordion Guy. They're only fought in one optional battle in front of the Yoshi Sphinx.
  • Mural Goombas and Mural Koopas are exclusive to Drybake Stadium.
  • Outside of the Big Cheep Cheep that serves as a midboss, Cheep Cheeps can only be battled on Whitecap Beach.
  • The Shiny enemies are usually pretty rare: Shiny-Cone Goombas are exclusive to Ice Flow, Shiny Bob-ombs to Bowser's Snow Fort, Shiny Paratroopas to Rugged Road, and Shiny Buzzy Beetles to Rumble Volcano.
  • Boos and Scaredy Rats can only be fought at the Enigmansion. There's also a few Boo variants — the Gold Boo, the Boo Stack, and the crumpled one in the trash — that can only be battled once.
  • Fuzzies are only in Whiteout Valley.
  • Normal Shy Guys are abundant in Bowser's Snow Fort, but the ones found with the Traveling Toad are not, and for good reason - they have 120 HP, ten times much as normal Shy Guys, and stronger attacks than anything else in the area.
  • Broozers are also found alongside a lone Boomerang Bro in Bowser Jr's Flotilla, and nowhere else. Rocky Wrenches are also exclusive to this level.
  • The only Whomp and regular Chain Chomp in the game are summoned as support during the final boss battle.
• Paper Mario: Color Splash: A ton, owing to the game's level-based structure - fortunately, missable/one-time enemies don't have specific Enemy Cards to themselves. Ironically, Red Snifits are the most common Snifit variant.
  • In Cherry Lake, you fight a Pry Guy in order to retrieve the journal he stole from Justice Toad. He has slightly higher stats than a regular Shy Guy, can shield from certain attacks, and has a unique set of dialogue that he runs through over the battle. Despite all this, he's quite easy to defeat.
  • Similarly, there's Laundry Guy, a one-off enemy from Vortex Island. He fights Mario using a magazine and exists to kickstart a small chain of battles in the laundry room. He has the same stats as Pry Guy, but no special battle dialogue.
  • Shady Sledge Bros are fought in two scripted fights, like the Pry Guy, and that's all. Aside from 8 more health and a Call-Back to Shady Koopas, they function identically to normal ones.
  • Mossrock Theater hosts a lot of unique circus-themed enemies: Ptooies, Roller Guys, Dino Rhinos, and Juggler and Circus Bros (which are somehow weaker than their regular counterparts).
  • Bone Goombas, stronger variants of Goombas, are only found in Marmalade Valley.
  • The sole Sombrero Guy in the game is found on the Sunset Express, but he does show up in other enemy battles in that area if he is not defeated first.
  • Some variants of Snifits and Shy Guys are only found at Plum Park. Poison Bloopers can only be found when the park is poisoned, and change to normal Bloopers when it's restored, meaning you can go an entire playthrough without fighting one. Blooper 10-Stacks are also exclusive to Lighthouse Island.
  • The only green Snifits in the game appear in Sunglow Ridge. Similarly, pink Snifits are only fought in Mustard Cafe.
  • The incredibly powerful Mega Goombas only inhabit Mondo Woods. Inversely, small enemies can only be found in the Sacred Forest.
  • Paper-Cone Goombas return from Sticker Star, although they're exclusive to Kiwano Temple. They also don't have Enemy Cards.
  • Paragoombas are incredibly rare this time around, where Whistle Snifits can rarely and randomly call them in. Whistle Snifits are also exclusive to two levels, being Mustard Cafe and Fort Cobalt.
  • There is only one Buzzy Beetle Gang, which lurks at the bottom of the parallel lighthouse on Lighthouse Island. It's incredibly difficult to defeat.
  • Shy Guy 5-Stacks appear in a few levels, but the 4-Stacks inhabit one area of Cherry Lake.
  • There's only one Scaredy Rat 10-Stack, which is a required fight in Toad Trainworks.
  • Fire Bro 8-Stacks are fought rarely in Redpepper Volcano and nowhere else.
  • Pokeys and their green variants are exclusive to the underground area in the Mustard Cafe.
  • Koopa Paratroopa 10-Stacks are only randomly summoned by Larry during his boss battle.
  • The Chariot Bro and Chariot Snifit only appear assisting Iggy in his boss battle.
• Paper Mario: The Origami King:
  • There is exactly one battle against a Shoe Goomba, which is in Breezy Tunnel. Hitting enemies in the Boot Car instantly kills them, and it's obtained in this area, so it's not hard to run the Shoe Goomba over and never directly fight it.
  • Fly Guys only appear while sailing across the Great Sea.
  • Shangri-Spa holds the only Chargin' Chucks in the game, which are a required battle. They don't respawn and can't be fought again.
• Mario & Luigi: Superstar Saga:
  • Goombas are tutorial enemies on the Koopa Cruiser and never reappear after the airship crashes, though they get a few variants throughout the game.
  • The Piranha Plants in the Beanbean International Airport; Only five appear in the overworld, and defeating them in battle only causes them to respawn. To get rid of them for good, they must be doused with water, and then Luigi must use his Thunderhand ability to defeat them instantly. After Mom Piranha is defeated, they never reappear again.
• Mario & Luigi: Partners in Time:
  • The regular Shroobs in Hollijolli Village; Only three are fought in the entire game.
  • The Guardian Shroobs in the Shroob Mother Ship; Only two appear in the overworld, with a total of nine appearing in the whole game. After the Mario Bros. fall out of the Shroob Mother Ship, Guardian Shroobs cannot be battled again.
• Mario & Luigi: Bowser's Inside Story
  • The Elite Goombule. Only two are ever encountered, directly after unlocking the Green Shell attack. The Player's Guide doesn't even bother listing them in the Enemy Compendium.
  • There's also the boss-exclusive enemies, including Leaf Guys (Wiggler), Biffidus (Durmite), Junker Cans (Junker), Snawfuls (Blizzard Midbus), and Dark Satellmites (Dark Star).
• Mario & Luigi: Dream Team has a single Monolift R roaming around the Ultibed quest-section of Mount Pajamaja. On the one hand, it does respawn if you kill it (but only after defeating a specific amount of other enemies each time, which is why they have Expert Challenges connected to them like more common enemies). On the other, the only other enemies in the area where you can find it are Viruses, which are only joined in battles with other Viruses.
• Mario & Luigi: Paper Jam has Fly Guys, appearing exclusively during specific missions and sidequests and nowhere else, making them the only non-overworld enemy in the game.
• The first Mario Party has strange-looking Spike Koopas, which appear only in the Mini-Game "Key-pa-Way" and nowhere else in the series.
• Wario Land:
  • The original Game Boy version of Wario Land II has exactly two "Kamukamu" fish: one in a waterway in "Turn off the giant faucet!" and another at the very end of "Escape from the Tea Cup!". In the Game Boy Color version of the game, these enemies are completely unused, replaced by the much more common sawfish, despite reshaded sprites existing for them.
  • In Wario Land 3, there is the Red Lump in The Peaceful Village, a lone Para-Goom with a pink-and-blue umbrella instead of the standard grey, red, green or blue in the first switch room of the green chest area of A Town in Chaos and in the tutorial videos for certain moves, and a single red Omodonmeka in the blue chest area of The Warped Void.
  • In Wario Land: Shake It!, Buccaneros only ever appear once in the tutorial level... and maybe very rarely late in the battle with Large Fry. Also, the evil treasure chests that eat Wario only appear three times in the level Boogie Mansion, are blasted open to get treasure, and don't respawn.
• Every level in Wario World except for Greenhorn Forest has at least one enemy unique to it.
• Wario: Master of Disguise: There are eight enemies that only show up once each: Spoonatic, Slaughterfork, Jack the Knife, Stankulus, Tooty Kamen, Blamses, Mellow Kitty, and Stuffy the 5th.
