Segmented Serpent

The Segmented Serpent is a snake-like or worm-like enemy which is made up of lots of individual body segments, all joined together in a line. This is a simple way to allow for interesting dynamic flexing and bending movements in a 2D sprite-based game, although the same principle can work in three dimensions as well. In its simplest form, a Segmented Serpent is simply a line of enemies following an invisible track, giving them the impression of being a larger composite creature.

This enemy type is very common in scrolling shooters. Because it normally appears in 2-dimensional games, it can often move through its own body and form closed loops to trap the player. Burrowing into the surrounding terrain and reemerging is another common tactic.

There are many different design variations on this idea, some exploiting the unique properties of a segmented creature to come up with interesting gameplay mechanics. Common ones include:

Being made of multiple sprites, Segmented Serpents are often quite large, usually larger than the player. They often appear as end of level bosses due to their spectacular appearance and their potential for interesting gameplay. They can be given weapons, but more often than not, their sheer size and dangerous movement is enough of an obstacle.

When a Segmented Serpent is destroyed, it's common for them to explode segment-by-segment from the point of destruction.

    Action Adventure 
  • In The Legend of Zelda series:
  • La-Mulana has Amphisbaena, Bashumu (a Mini-Boss in the Dimensional Corridor) and Nu Wa.
  • DeepDive dragon boss from An Untitled Story. Strange in that he is a Stationary Boss, and his weak point is one specific segment of his neck.
  • The Basilisk in the Harry Potter and the Chamber of Secrets game of the movie is this.
  • The boss Centipede in Deadly Towers.
  • The Shadow Snake in "Shounen Kininden Tsumuji".
  • In Pikmin Adventure one of the later bosses is a large Centipede monster on wheels. It attempts to bite the Players. It's body segments are it's main weak spot. A segment that breaks off becomes a whirling Top of Doom that tries to attack players.
    • The best part? When you kill all it's body segments it Turns Red and starts doing a charge-up version of it's usual Bite move. It's weakspot is only viewable during the charge but it doesn't move either. After this is beaten it simply charges around with a single weak point, making it arguably tougher. The damaging tops are there in all three parts of the fight.
  • Several of the bosses in Terraria fit the Asteroids Monster model. They can be very tough to beat the first time (because you probably won't have access to the really good weapons yet), but since the game world is almost infinitely customizable and most bosses don't appear until certain triggering events you can improve your chances significantly by building an "arena" to fight them in ahead of time.

    Action Game 
  • Gunstar Heroes loves this. To list some of the more obvious bosses:
    • Seven force manages to do seven bosses out of the same set of segments.
    • Valvalis in the Dice Palace
    • The Core Guard System's "Unit of the Dragon".
  • An early boss in Strider is a long, segmented Transforming Mecha that slithers around in the air and is made of politicians.
  • Orchidee, the third proper boss of P.N.03, is a mecha-centipede on rails.

    Beat Em Up 
  • Battletoads for the NES had these. But instead of killing them, you had to climb them as they slithered around spiked balls hovering in the air.
    • The Battletoads arcade game's second boss was abit of a subversion in that one of these snakes was a boss. It still looks segmented, but all he does is bite at you from the background.
  • Muramasa: The Demon Blade features a couple of centipedes as Kisuke's second boss that crawl over the buildings and fire flames out of the various segments.

    Platform Game 
  • Fracktail and Wracktail in Super Paper Mario.
  • Fire Snakes in Super Mario Bros. 3.
  • Wigglers from the Super Mario Bros. series. Technically, they're actually more like caterpillars, but the way to defeat them focuses on killing each segment at once.
  • Super Mario 3D Land featured floating snakelike enemies made almost entirely out of brick and "?" blocks.
  • Donkey Kong Country Returns has the boss Mangoruby, a plant-like serpent with an electrified body. In order to attack it it's body must first be de-electrified
  • Super Metroid features Botwoon, the water serpent. Metroid: Fusion features Serris, a snake with super speed. Metroid: Zero Mission features the Charge Worm and Acid Worm. They all must be shot in the face.
  • Dynamite Headdy has a skippable robot dragon Mini-Boss on the upper path toward the end of Scene 2-2, which can be fought for a Secret Bonus Point.
  • Megapede, the final arena boss in Ratchet & Clank: Going Commando, where blasted-off segments turn into irritating cannons that distract you from the main boss.
  • Alien Soldier has about four enemies of this variety. Oddly, one of them attacks by breaking apart and hurling all its segments at you.
  • Turns up from time to time in the Sonic the Hedgehog series. The Caterkillers from the first game come to mind, as do the Caterkiller Jr.'s in Sonic 3, and from Sonic and Knuckles, the jumping worms in Sandopolis and the flying worms in Lava Reef. Also, the first phase of one of the bosses in "Sonic2" involved this, plus one of the bosses in Sonic Advance 2. Sonic Advance 3 also involved these as a regular enemy.
    • Eggman builds one as the final boss battle in Sonic's storyline in Sonic Adventure.
  • In Mickey Mouse's Magical Quest the first boss is one of these, and you can knock the segments off to throw back as a missile weapon at him.
  • Crystal Caves has a rare enemy which looks like a green snake built of four segments. Shooting it in the head causes it to become shorter.
  • Mega Man 7 has these in Junk Man's stage.
  • Mega Man X has two on Launch Octopus' stage: One that actually obstructs the path leading to the boss, and must kill to advance, and another that blocks the way to a secret Heart Container. Neither can be harmed in any way except by shooting the head or the tail, and those are the only parts that can hurt you, so you can go for a ride on its body and pelt the head or tail with shots as much as you want.
    • In Mega Man Zero 2, a variation is used in an early boss fight, where it's the battlefield that's the segmented serpent. The boss is simply a snake-themed robot master.
  • One of the bosses fought in world 8 in Monster Party.
  • Bug! has a borderline example in the form of... "caterpillars". They will fire out their "segments" one by one, and only after all the segments have been fired out will the "head" (actually an insect by itself) run away and become vulnerable.
  • Terraria has a variety of worm and serpent enemies that take this form, but the most significant ones are the bosses: Eater of Worlds, whose segments can break off and function on their own, and The Destroyer, who is extremely long, can shoot lasers from its segments, and can deploy drones from its segments to shoot even more lasers at you.
  • Ghosts 'n Goblins has multiple battles against dragons of this type.
  • A curious example is the giant earthworm that appears in Hammerin' Harry. It extends its front part to squirt blue stuff at you and generally looks very out of place in the game.
  • Stinkoman 20X6 has Saargtsson, a giant snake that jumps out of lava and shoots lasers at Stinkoman.
  • Green Grub from Kid Niki Radical Ninja, whose segments become skeletonized as you fight it.
  • The red worm boss of Stage 5 of The Legendary Axe II.
  • The 3-D Battles of WorldRunner has the Alien Serpentbeasts, fought in the Boss Battles at the end of every stage.
  • In Dragon Egg!, the fifth boss is a segmented dragon that circles around and loses segments when hit.
  • Bone Dragons in the Castlevania series.

    Puzzle Game 
  • In Gomola Speed for the PC Engine, you play as the head of a worm-like creature and join up with other segments, which will scatter if you get hit. The object of the game is to eat food by enclosing it; enemies can also be defeated this way.
  • Jetpack has the so-called Marble Worm. It's actually not a single enemy but a bunch of Steel Balls lined up in a row, though they can't be separated. This comes up again in "Double Wormage."
  • Trauma Center has Paraskevi, a nasty variant that must repeatedly be sliced in half until each part is just one segment. And each part aims to escape towards the heart and needs to kept stunned.

    Rail Shooter 
  • The dragons in Space Harrier are quite impressive-looking examples of this for a 1985 game. Averted in the PlayStation 2 remake, where the dragons have more complex 3D models.
  • Night Striker has the Dragon Head bosses, which are robotic sea worms. Unlike most examples, their whole body is vulnerable. Which is a good thing, because you'll have to fight more than one in later levels.

    Real Time Strategy 

  • NetHack includes the long worm, which will likely split in half if you attack the middle.
  • Larry Jr. and its improved form, the Hollow, in The Binding of Isaac, as well as Pin and Scolex to a lesser extent. The first two have the segment-by-segment destruction and the capability to split into two if cut straight down the middle, while Scolex is only vunerable to shots that hit its tail. Interestingly, the fact that each segment takes damage for the whole unit means that you can hit them with something that hits all the parts at once (like piercing shots, lasers, or a Herd Hitting Attack) for massive damage.

    Role Playing Game 
  • One of the toughest viruses in the first Mega Man Battle Network is a three-segmented serpent. It couldn't trap you, but it could easily block attacks to its head with its two body segments. Luckily, you only ever have to deal with just the snake, being one of two virus types that are only ever fought by themselves.
    • Mega Man ZX, on the other hand has Giga Aspis, which as an intro level boss is one of the easiest enemies you'll face.
  • The Pot Centipede from Kingdom Hearts. Actually, the monster itself was nothing but the head and tail piece; the rest of it was made of of Pot Spiders. While you could destroy the Spiders to make the Centipede smaller, the only way to deal damage to the boss itself is to attack the head or tail.
  • Secret of Mana has two snake bosses like this.
  • Pokemon Ranger subverts this with Steelix. It's made up of several chained segments, unlike all the other Pokemon in the game, but due to the way the game plays you don't target the segments at all. Instead, you have to draw circles around the whole beast in a continuous loop while it slithers around, with the segmentation simply making it bigger and more flexible. Known for being very, very, hard.
  • Zigzagged in Final Fantasy XIII, of all games. The fal'Cie Dahaka is a flying serpent creature that resembles a chain of beads, and while the "bead" segments do have to be destroyed, it's not part of the critter's boss fight, but rather done in cutscenes by the Menhirrim, not the party. But in true Segmented Serpent form, Dahaka will only die after you take out its "head" segment.
  • Ys I has Nygtilger (who gets a full 3D makeover in Ys Origin), and Ys III has Gilan the fire dragon.
  • Vaides, the dragon in Dragon Slayer Jr Romancia.
  • The giant wiggler from Mario & Luigi: Bowser's Inside Story. Unlike many examples, you have to attack the segments first as its head is invulnerable until all the body segments are turned yellow. Once you do so, the head can be attacked, but only for a short while- the wiggler will turn red again after a few turns, forcing you to repeat the process.

    Shoot Em Up 
  • Gradius V has huge wormy monsters with vulnerable heads or tails. The ones in the Womb Level are actually downgraded versions of Gradius Gaiden's first boss.
    • A fire serpent enemy from the NES version of Gradius II, which was previously a boss in the arcade version of Salamander/Life Force.
  • R-Type has long, indestructible worms which coil around the player and seem to be one with the boss, a giant heart.
  • Recca had these as normal enemies, as well as sub-bosses. Like most examples they can only be attacked in the head.
  • In the Hunt had a long, ancient fish with a vulnerable head as the Mini-Boss of the fourth stage.
  • Bio-Hazard Battle has a few enemies like this. Like many other games, their weak point was usually the head.
  • Bio Metal had these as regular enemies, as well as the fourth boss.
  • Apidya has an eel like this. Again, only the head can be damaged.
  • Project X
  • Steel Saviour has these in stage 2, as well as the boss of stage 4.
  • Bio Ship Paladin has these as Giant Mooks. One of which you will encounter is seemingly indestructible, but actually isn't.
  • Geometry Wars features these.
  • The fifth boss in Super Star Soldier represents this very clearly- the thing is huge and consists entirely of joints, and moves very very fast. The fifth stage also features regular enemies of this wormy type (appearing one and a half minutes into this video).
    • Star Parodier has some odd takes on this: a flying roller coaster train at the end of the first stage, and a string of triangle blocks that rearrange themselves into various shapes at the end of the second.
  • Star Fox Command has quite a few of these, including two bosses. Sometimes all segments need to be shot, sometimes only the head (but shooting all other segments first will give more points).
  • Centipede. Blowing up a segment within the body of the centipede results in multiple centipedes, and individual segments are also mobile.
  • Eliminate Down has the first Mini-Boss as one of these.
  • Heavy Weapon has the Mechworm boss, which had its head as the weak point. It also had three segments that tossed out bombs, these could be destroyed, however, destroying all three segments will make the head start using a Macross Missile Massacre.
  • Irem's Dragon Breed and Jaleco's Saint Dragon have the player controlling one of these.
  • Shadow of the Ninja had a pair of these as a miniboss in Stage 2-1.
  • The second boss of Wonder Boy III Monster Lair.
  • The Dragon Laser in Lightning Fighters, a Smart Bomb-like special weapon that flies around the screen obliterating enemies.
  • Rezon has these as an enemy type in Stage 2 and also as a boss that stretches the width of the screen.
  • In Elemental Master, the water dragon boss composed of segments, unlike all other dragons in the game.
  • Gynoug has a Mini-Boss like this. It moves in tight circles at first, then wider and faster across the screen.

Non-video game examples:

    Anime and Manga 


    Tabletop Games 
  • Mortasheen takes this to silly lengths with the Bratwurm, which is one of these made entirely out of hot dogs!
  • Spine chains in Exalted. They are made of animated skeletons.
  • One made out of animated corpses shows up in the sample adventure in early editions of Palladium Fantasy RPG.
