Western Animation: Slugterra
"Slug it out!"
— Series motto

An animated action/adventure series set in more or less our world with one pretty big exception: the existence of a sprawling underworld called Slugterra. The series is set entirely in this subterranean land and follows Eli Shane and his new friends as they travel and act as protectors of the people. It is basically a Mons series with a twist.

For generations, the men of the Shane family have acted as protectors of Slugterra. When Will Shane mysteriously disappears, Slugterra is left without a Shane. However, in the last moments before his disappearance, he sent one of his slugs, Burpy, to his son on the surface. A few years later, honoring a deal he made with his father to wait until his fifteenth birthday, Eli Shane journeys down to Slugterra to follow in his father's footsteps and become protector of Slugterra.

Eli quickly makes friends to help him in protecting Slugterra: Pronto, the Molenoid (self proclaimed) master tracker; Trixie, the girl with the camera, ready to document the world; and Kord, the strong cave troll/team mechanic.

A refreshingly new spin on the Mons concept, this show is brought to you by the creators of Dragon Booster, Storm Hawks, Hot Wheels Battle Force 5, and League of Super Evil. Link to the official site.


  • Action Bomb: Some slugs explode on impact, such as in a shower of sparks, or at least disappear. They're always fine when they show up again.
    • Grenuker (supposedly a portmanteau of grenade and nuke)
  • Action Prologue: The series opens in the middle of a battle between Will Shane and Dr. Blakk. This happens again in Keys to the Kingdom
  • Abnormal Ammo: Slugslinging.
  • The Alcatraz: Stalag-mite 17 in "Mission Improbable".
  • All Trolls Are Different: "You'll never find someone more loyal, honest, and brave than a cave troll." And they're known as the best engineers, crafting many of the passageways used in Slugterra. Though the website refers to "cave troll rage".
  • Aluminium Christmas Trees: "Mario Bravado". Spitting and chewing gum really are against the law... in Singapore.
  • Always Chaotic Evil: The Shadow Clan, though Eli believes they might be Chaotic Neutral. As of Inheritance, it looks like Eli is correct.
    • Played straight with the Dark Bane.
  • And the Adventure Continues: The third season ends with Blakk, his minions and the Dark Bane banished. Eli decides to stay in Slugterra and seals the drop just before the Shane gang faces against Blite riding a dinosaur. This is the series finale, at least until the movie.
  • Animesque
  • Anti-Magic: Regular slugs can’t transform in the Dark Bane’s realm.
  • Artificial Limbs: The Old Master engineer Redhook. Let's just say it's a Meaningful Name.
  • Artistic License - Geology: Slugterra is "over 100 miles" beneath the surface. The Earth's crust averages about half that thickness.
  • Artistic License - Statistics: Mario Bravado to Eli Shane. "Remember, 90% of trick shooting is half mental." Eli gives him a look.
  • Ascended Fanboy: When Kord gets to join his favourite slugball team in "Slugball".
  • Aura Vision: Enigmo Slugs can grant this to the one they slugged. Eli uses this to find out slug combos.
  • Bad Bad Acting: When the gang have to set up an ambush in Shane's absence in "The Lightwell".
  • Bait and Switch: "The Slug Run". The one mechabeast racer depicted as The Ace and having some Blakk tech seems the most likely to be working for Blakk; it's actually Pronto's Unknown Rival, depicted as The Ted Baxter.
  • Bar Brawl: Early in "A Distant Shore".
  • Basement-Dweller: Invoked with the Gamemaster in "Thrill of the Game".
  • Beneath the Earth: Slugterra. The Dark Bane world is even ‘‘further’’ underground.
  • Big Bad: Dr. Blakk.
  • Big Ball of Violence: Episode 3, The Trade. Eight slugs are fired against each other at once and the result is a big blue/red glowing ball suspended in the air.
  • Big Damn Heroes: Done at the end of "The Journey Home" - with SLUGS! In a mammoth-type mechabeast!
  • Bigger Bad: Brimstone, Leader of the Darkbane Tribe
  • Blessed with Suck: The whole transformation at 100 mph ability is completely involuntary, meaning that mere falling slugs become a huge problem in the Cold Open (heh) of "The Slugout".
    • The above mentioned Aura Vision. You can't see anything else.
  • Bloodless Carnage/Non-Lethal Warfare: Some slugs have incredibly destructive powers, but no one ever gets hurt. Possibly justified by the Functional Magic based powers of the slugs.
  • Bread, Eggs, Breaded Eggs: Pronto in the episode Mario Bravado explaining how his (nonexistent) crime organization will bust him out of jail.
    "It's about fear, and respect. Kind of a... fearful respect."
  • Brick Joke: In "Slugball", the commentators' comments on dedicated ring technicians leads to a Gilligan Cut to the actual technicians discussing how to get rid of mustard stains. Later on, Kord's near impossible goal is described by one commentator as "my favourite day after the time I got that mustard stain out of my pants!"
  • Bullet Time: All over the place. Bear in mind these 'bullets' take a little more animating than most.
  • Call Back: In "The Journey Home", the slugs pass through the mall from "Dawn of the Slug", and even that mall cop puts in an appearance.
    • In "The Gentleman And The Thief", a montage of Dana Por's victims shows Mario Bravado, the fishman-pirate, and yes, the mall cop.
    • The miners from the Halloween Episode reappear in "No Exit".
    • King of Sling, the Ted Baxter beaten by Trixie in episode 2, gets his own episode down the line.
    • "Mission Improbable" has Mr Saturday from "Dawn of the Slug" in The Alcatraz. The fact that he was last seen getting arrested even fits - thanks to his old mind control gimmick, he's literally Running the Asylum.
    • The Ted Baxter Molenoid from "The Slug Run" returns for "Keys to the Kingdom".
  • Call to Agriculture: The titular Mario Bravado, trick shot celebrity who's now running a pizza place.
  • Camera Fiend: Trixie.
  • Casting a Shadow: The Shadowclan.
  • Chekhov's Gun: Played with in "The Hard Part". A water stain on the map turnsout to be a leaking pipe - which doesn't do anything, but Eli's slugs get the drop on Boss Ember by dislodging an identical pipe to create a landslide of junk.
  • Chekhov's Skill: The trick shot skills that Mario taught Eli become useful again in The New Kid, Part 2.
  • The Chew Toy: Pronto.
  • Classy Cat-Burglar: Dana plays this one straight - but with SLUGS! And a Shadowtech MacGuffin.
  • Cloudcuckoolander: The Enigmo slug (though it could also be Too Dumb to Live, since it fails to realize that some of the traps are deadly).
  • Color-Coded for Your Convenience: Normal slug canisters are blue (good and neutral slugslingers), while Ghouls come in red ones (evil or aligned with Dr. Blakk).
    • Green is for Techno-slugs.
  • Com Mons: Floppers are the weakest slugs and Pronto even calls them useless. They're the only slugs that don't transform at speed, only exploding in a cloud of gas.
  • Concealment Equals Cover: Played straight in the Bar Brawl in "A Distant Shore". Kord even uses a table as a shield!
  • Convection Schmonvection: The occasional underground lava field. Possibly justified due to the Functional Magic of the slugs and Slugterra itself.
  • Cool Bike: In the episode Upgrade, Kord gives the Shane Gang's mechabeasts an upgrade that allows them to switch between their normal mode and this mode.
  • Cool Pet: Burpy often sits on Eli's shoulder, he can set his head on fire for light, and he also turns into a flying flaming manta ray creature when he's shot out of a blaster at 100mph. The rest of the slugs fit as well.
  • Corrupt Corporate Executive: Blakk acquired the land rights to build the Slugterran express by force.
  • The Corruption: Dr. Blakk's nefarious schemes involve turning all slugs into vicious, evil versions of their species called "ghouls".
  • Crippling Overspecialization: Eli's first real duel is with a guy who only uses Tazerlings. He's a one trick pony, but it is a pretty nice trick. He loses because Tazerlings tend to misfire if they get tired out from overuse, shocking himself.
  • Curse Cut Short: In The New Kid Part 2, when he realised he was about to get defeated, Diablos said "Oh..." before he got hit.
  • Cyclops: Eli fought against one of these.
  • Dangerous Sixteenth Birthday: Subverted - it's actually 15th, and Eli's choice entirely. Just, yknow, it's part of Will's last instruction.
  • Dark and Troubled Past: Dr. Blakk.
  • Dark Is Evil: The Dark Bane.
  • Dark Is Not Evil: The Shadow Clan.
  • Day in the Limelight: The Journey Home for Eli's slugs.
  • Dead Man Writing: Will Shane sends Burpy to lead Eli to a prepared message.
  • Defeat Means Friendship: Played with as slugs don't really get the concept of defeat as applies to their sluggers - but they can pick a better master.
  • Diminishing Villain Threat: The Ghoul Slugs are depicted as nigh unbeatable in their first few appearances, but gradually start getting beaten more easily. (Justified, perhaps, by the Shane gang's growing skill, and by the addition of Doc to Eli's ranks, which makes it so Blakk has to conserve them more).
    • Dr. Blakk’s forces seem to be averting this, becoming more dangerous as the story goes on, what, with the Gatler (essentially a Ghoul-firing ‘’machine gun’’, the Titan tanks, and four Dark Bane to his group.
  • Disappeared Dad: Will Shane disappeared when Eli was young, though Eli knew all about Slugterra.
  • Disembodied Eyebrows: Pronto, and most likely all Molenoids, since the Unknown Rival also has them.
  • Do Not Touch the Funnel Cloud: One slug has the effect of causing a tornado that only seems to affect the person it hits.
  • The Dragon: Diablos Nacho, who works for Dr. Blakk or so it seems at first. He actually works for Brimstone, High Commander of the Dark Bane.
    • Twist has apparently taken his place.
  • Early-Bird Cameo: Diablos Nacho and Twist have been in the intro since episode 1.
  • Elemental Powers: Some slugs have powers like fire, water, and tornadoes. Each slug has an elemental designation, though some are harder to guess.
  • Elemental Rock-Paper-Scissors: Averted. Though slugs have an element, since they don't do direct battle their elements don't seem to make much of a difference.
  • Embarrassing First Name: Beatrice Sting. She prefers to go by Trixie.
  • EMP: The Xmitter slug from "The Hard Part".
    • Picking a bad match of slugs for a combined shot will have this effect with every slug in the area.
  • Enemy Of My Enemy: "Dark Water Deep Water" invokes AND subverts this when the Shane gang must work with the fishman-pirate Malvolio Drake to take down a Blakk mining facility, run by Drake's own brother. The pirate's misunderstanding with his brother is cleared up like that, leaving the Shane gang alone against the both of them.
  • Enemy to All Living Things: Invoked when Blakk's actions cause all regular slugs everywhere to turn against him. Becomes an Ironic Echo when Twist suffers the same.
  • Everything's Better with Spinning: Thresher slugs grow razors out of their backs and spin like a buzzsaw while flying through the air.
  • Evil Is One Big Happy Family: Played straight and averted. While Blakk’s men and the Dark Bane seem to work together OK, villainous factions have clashed with each other.
  • Evil Makes You Ugly: Dr, Blakk’s Dark Water experiments and subsequent trip to the Deep Caverns made him uglier (and his mundane evil actions before that seem to have been doing this to some extent).
  • Family-Friendly Firearms: Showing kids pointing guns at people's heads is apparently OK when the ammunition is just so darn cute!
  • Fanboy: Kord is this to Mario Bravado.
  • Fantasy Helmet Enforcement: In "Upgrade". Eli and Trixie are going to need helmets to handle the mechabeasts in bike form, but apparently the headgear on Kord and Pronto work fine.
  • Fartillery: Flatulorincus.
  • Fastball Special: In "The New Kid pt 2" - Molenoid Longbomb!
  • Fire, Ice, Lightning: Eli's primary slug is an Infurnus, and the first slug he wins in a battle is a Tazerling. Frostcrawler completes the trio.
  • Five-Man Band:
  • Flat Character: The main characters. Aside from generic traits (Eli being The Hero, for example), there isn't much else.
  • Foreshadowing: In Endangered Species when Eli was still suffering from the effects of the Enigmo slug, one slug he was looking at seemed to stand out brighter than the surroundings.
    • Slugs fired at each other at precise timing turn into a Big Ball of Violence. What happens if they're aimed at the same target instead of each other? Combo attacks.
    • All mechabeasts have knobbly tyres someplace on their bodies long before "Upgrade".
  • Four-Fingered Hands: Cave trolls and molenoids, but not the humans.
  • Functional Magic: The slugs are magic.
  • Fish People: They ran into a group that are pirates.
  • Fungus Humongous: Obligatory giant underground mushrooms abound.
  • Fun Size: The slugs, and even their larger destructive forms are still rather small.
  • Gangsta Style: Derided by Eli when he sees it in a movie; He points out that holding a blaster sideways interferes with the trajectory.
  • Gasshole: Stinky. He is a Flatulorincus, after all.
  • Gentle Giant: Kord is huge and imposing but very friendly. And according to Eli's father, you'll never find a more loyal friend than a cave troll.
  • Good Old Fisticuffs: Bludgeon slugs have big ram's horns when transformed. What do they do? Punch you.
  • Gotta Catch 'Em All: Not a goal per se, but in official slugslinging rules, the winner is allowed to take one slug from the loser. Also played straight, since catching slugs in the wild is also a thing.
  • G-Rated Drug: The slug accelerator from "Club Slug" has the effect of G-rated steroids, down to the slugs needing a regular fix afterwards.
  • Grenade Launcher: Blasters act like this with exploding slugs.
  • Guns Akimbo: Not as much as you'd expect despite the premise. There's Boss Ember for one, who takes it Up to Eleven by quadruple-weilding blasters.
  • The Gunslinger: Everyone. It's even called "slugslinging".
  • Halloween Episode: "Deadweed" turns out to be a subversion, as the Dark Water is revealed this week.
  • Hammer Space: Not overt, but most slugslingers only have about three slug canisters visible on themselves (usually across the chest or on the hip), yet they carry and use far more than that.
  • Hard Work Hardly Works: Averted, we see that the Shane gang is training a lot of the time.
  • Head Desk: Burpy of all people, when Pronto tries to claim credit again at the end of "The Journey Home".
  • Heart Is an Awesome Power:
    • The Enigmo slug is more useful than it first appears.
    • Doc was more useful than his previous user thought.
    • At one point, Eli manages to use only a few slugs with powers his opponent considered weak to last until his other slugs got there.
  • Hidden Depths: Who knew Pronto was the KING of the Molenoids. Even the rest of the Shane Gang were surprised.
    • Lock and Load let another Blakk minion attack his prison first, so they could analyze the defenses.
  • Horseback Heroism: "Mechaback" dueling is an official form of slugslinging.
  • Horse of a Different Color/Mechanical Horse: Mechabeasts, which come in several flavors.
    • The gang ride around on a mechanized police dog, panther, warthog... and a donkey.
    • The Hooligang from "The Slugout" all get hyenas.
    • "The Slug Run" is filled with these - there's a bull, an elephant, a mole, a chicken, even a giant snake. Vance Bolt may be the only one whose mechabeast actually resembles a horse.
  • Humongous Mecha: The villain of the episode in Roboslugs pulls one out that forces the Shane gang to make one of their own.
  • I Call Her "Vera": Not a straight example, but Eli may come across as this to some people in-universe, as evidenced by Pronto's reaction to hearing Eli talking to his slug, Burpy. He is technically naming his ammo.
  • Identical Twin ID Tag: Brothers Locke and Lode. Locke has a thick beard, Lode has multiple shaving cuts on his face.
    • There are also triplets who wear different-colored suits.
  • Impossible Thief: Dana Pors portrays herself as such using Shadow Clan Tech.
    • The beginning of "The Gentleman And The Thief" is a lovely example. She takes Mario Bravado's pizza while he's still tossing it!
  • Improbable Aiming Skills: Eli performs a near impossible shot with an Armashell slug he just obtained, after being told it would take weeks or longer to build a bond strong enough to get a slug to do exactly what he wanted with that much precision. It just went to show how quickly he builds a friendship with his slugs.
  • Instant Expert: It should be noted that Eli's entire slug experience until he turns 15 is probably from books until he got to enter Slugterra.
  • The Inner Reveal: Eli decides to reveal what he knows to Trixie, Kord and Pronto about the Shane secrets in The Distant Shore. This includes revealing the surface world is real and that's where the Shanes came from.
  • Joke Character: Flatulorincus slugs harness the power of farts.
  • Just a Kid: Everyone's reaction to Eli in the first episode. And disappointment when expecting a Shane.
  • Kid Hero: Eli heads down to Slugterra on the night of his fifteenth birthday.
  • Killed Off for Real: The Unbeatable Master, Shinai, in the episode she debuts in.
  • Lantern Jaw of Justice: Kord!
  • Large Ham: Pronto is this in SPADES.
  • Laser-Guided Karma: The corrupt judge in Mario Bravado was put away by his own draconian laws. It looked like his underlings really enjoyed taking him in when that occurred.
  • Laser Hallway: in "Mission Improbable", of course.
  • Legacy Character: They don't pretend to be the same man, but "The Shane" is a title each generation of Eli's family has accepted.
  • Lethal Joke Character: Flatulorincus can be just as effective as other slugs if used properly.
  • Like Father, Like Son: Eli even looks a heck of a lot like his father, Will.
  • Loyal Animal Companion: Eli's slugs. After winning a duel, he even asks which one wants to join him on an adventure, rather than just picking the strongest, to ensure they'll be this.
  • Made of Evil: Dark Water. It has ways of messing with people, and it is used by Blakk to turn Slugs into Ghouls.
  • The Masquerade: One on both sides; Slugterra is kept in the dark about the surface and vice-versa, the only known link between the two is the Shanes and the lift they use to travel between them.
  • Master of Illusion: Twist's slug Loki is this. It doesn't help that it's a Ghoul.
  • Meaningful Name: It's just a little ironic that the person responsible for the Dead Man Writing is named Will.
  • Mechanical Horse: (See also: Horse of a Different Color) Mecha-beasts are a common mode of transportation in Slugterra. We even see carts being pulled by mechanical bulls.
  • The Medic: Healer slugs. They also have the ability to cure slugs that have been ghouled.
  • Meet Cute: Eli and Trixie. In their first encounter, she saves him from a bandit with one shot and then rides off because she's in a hurry. The next time they meet...
    Trixie: "Excuse me, you're in my shot."
  • Mentor: Subverted. Will Shane had hoped to be this for his son on his first trip to Slugterra.
  • Metaphor Is My Middle Name: In "The King of Sling":
    Eli: Okay, guys; Quick, slick and sly.
    Pronto: Ah, three of my many middle names!
  • Mole Men: Pronto is a Molenoid. They are known for having great sense of direction due to a natural, built-in magnetic compass. However, this has gone to his head.
  • Mon: The slugs definitely come across this way, even if they don't do one-on-one battle.
  • Morally Ambiguous Doctorate: Dr. Blakk.
  • More Dakka: Standard blasters are comparable to the typical handgun. In The Unbeatable Master, Dr. Blakk pulls out something comparable to a giant machine gun called a gattler. Kord says it's probably the first working model of such a weapon.
  • My Species Doth Protest Too Much: Kord's clan wanted him to go into the family business of engineering, but slugslinging was just way more fun. He still tinkers, though.
  • Never My Fault: The Gamemaster in "Thrill of the Game", doesn't reveal all the rules of his game till it's too late, still accuses them of cheating.
  • Never Say "Die": Will Shane is sucked into an uncontrollable vortex that leaves a blackened crater, but no one ever suggests he could be dead.
  • Nice Job Breaking It, Hero: Will Shane managing to convince the Slugs to abandon Blakk may have stopped him from forcing people to sign over their lands for the Slugterran Express, but it is what ultimately led him down the path to Ghoul slugs.
    • In "The Return", Eli attempting a two-slug combined shot without any practice creates something akin to an EMP for slugs, leaving them powerless as Blakk successfully destroys the mechabeast factory.
    • In "Mission Improbable" Eli does pull off a combo shot - except this time the resulting bludgeon-tornado turns on our heroes as well.
  • Non-Human Sidekick: Technically there's two, but Pronto is distinctly more nonhuman than Kord. If you wanna start counting the slugs though...
  • Nose Art: Kord's blaster.
  • No Sense of Direction: For a "master tracker" and explorer, Pronto seems to get lost often. He may get you to where you need to go, but it will be the scenic route and possibly through unnecessary peril.
  • Oh Crap: During The Journey Home, the slugs manage to show this by expression alone when they encounter various perils, like falling down a canyon, getting chased by a slughound, dealing with sharp electric saws and getting chased by Locke and Lode.
  • Omake: "Slugisodes", short clips hosted by Trixie that expand on The Verse, in particular, slugslinging knowledge.
  • Our Ghouls Are Creepier: Ghoul slugs are pure evil (being corrupted by Dr. Blakk), and more powerful versions of their original species. They're vicious, and named after a comment made by Eli after seeing one for the first time.
  • Our Zombies Are Different: There was a ghoul-hypno slug that turned everyone into brainwashed zombies that stole stuff for the caster in the episode Dawn of the Slugs. The fun thing is, it was set in a mall and the slug's master is a straight-up Voodoo witch doctor named Mr Saturday, covering both zombie archetypes in one go.
  • Parrot Pet Position: Burpy often spends more time on Eli's shoulder than in its canister.
    • The pirate captain does this for his lizard.
  • Pinball Projectile: The World Beneath Our Feet, Part 2: Eli intentionally causes multiple stalactites to fall with a single ricochet shot.
    • One slug's power is to ricochet off surfaces before reaching a target.
    • The Gentleman deliberately uses his Thresher slug (the spinning buzzsaw one) in this fashion.
  • Power Copying: The pirate captain's pet lizard is able to not only be used as ammo for a blaster, but can also mimic any of the slugs his opponent uses to blast at him.
  • Power Incontinence: Dr. Blakk's Ghoul slugs had this at first. He fixed it.
  • Power Walk: Leading up to the climax of "Dawn of the Slug".
  • Pun: The word "slug" is used in three ways. The creatures look like upright cartoon slugs, they're used as ammunition (like shotgun slugs), and the phrase "Slug it out" is used as a series motto ("slug" meaning a hard blow/hit, as in "slugfest" or "slugger").
  • Pursuing Parental Perils: Eli knows that his father disappeared protecting Slugterra, but he's still determined to follow in his footsteps.
  • Redemption Equals Death: Played with, See the Shane Gang faked Dana Por’s death to Blakk so he stop hunting her, And in return she turns over a new leaf and gets along better with Eli.
  • Renowned Selective Mentor: Shinai, the Unbeatable Master shows up at her own choosing to pick one student out of many hopefuls to teach.
  • The Reveal:
    • The New Kid Part 1: Twist is working for Dr. Blakk.
    • Inheritance: Will Shane had a device that allowed him to communicate with the Shadow Clan.
    • What Lies Beneath: Below Slugterra in the Deep Caverns is an entire evil race called the Dark Bane, and Diablos Nacho is one of them.
    • The Return: The Enigmo slug allows those hit with it to see the slug's aura to see which are compatible for a Fusion Shot.
  • Revolvers Are Just Better: Dana Por has a revolver slug blaster gauntlet.
  • Ridiculously Cute Critter: The slugs, of course! When below 100mph, that is.
  • Rival Turned Evil: Thaddius Blakk to Will Shane, after the Master chose Will over him.
  • Royals Who Actually Do Something: Pronto, who of course helps save and protect Slugterra.
  • Sadistic Choice: The Gamemaster in "Thrill of the Game" is all about these.
  • Sealed Evil in a Can: There is a whole evil race called the Dark Bane trapped beneath Slugterra, with all of Slugterra acting like a cork and keeping them sealed in there.
  • Shapeshifting: The slugs transform from cute little creatures into more powerful versions of their species, but only when traveling at least 100 mph.
  • Shout-Out:
  • Silent Snarker: The slugs on occasion.
  • Sixth Ranger Traitor: In The New Kid, Part 1 and Part 2, the Shane gang encounter a guy named Twist. He helps them out for a while, but by the end of Part 1, he is revealed to be in league with Dr. Blakk.
  • Small Name, Big Ego: Pronto the Magnificent; tracker, explorer, molenoid of many talents.
  • The Smurfette Principle: A proud tradition of Nerd Corps' action series, it seems. Trixie is the only girl on Eli's group.
  • Space Western: But UNDERGROUND!
  • Spanner in the Works: The fact that the Gamemaster researched our heroes to get into their heads but didn't bother with Pronto is precisely what allows our heroes to turn the tables.
  • Start of Darkness: "Back to Blakk" throws in a Freudian Excuse as well. Blakk's own father was a Snake Oil Salesman who was run out of town, leaving his son behind to be enslaved in a mine.
  • Sticky Bomb: There is a slug that sticks into walls with spines as its tail burns down like a fuse.
  • Stink Bomb: Flatulorincus/Stinkers.
  • Sufficiently Analyzed Magic: Although not completely explained, the Slugs' process of shapeshifting has been analyzed enough for application as a power source for the Mecha Beasts and to be wholly replicated in Robo-Slugs. It's even been named, Molecular Transference.
  • Super Mode: Not the slugs when they shoot out and change, but launching them from a vehicle already going at 100mph makes them evolve further!
  • Suspiciously Specific Denial: The World Beneath Our Feet, Part 2. Eli wins his first match of the tournament and goes to find Pronto watching another match. Pronto says he's certainly not looking for another job in case he lost.
  • Swiss Army Gun: Since each type of slug has its own effect, every blaster is this.
  • Taken for Granite: "No Exit". Neurotox slug (Which is a ghouled up version of a neotox slug) uses it toxic gas to turn opponent to stone until our heroes figure out how to reverse that effect.
  • Take Over the World: Dr. Blakk's plan, using his Ghoul slugs.
  • Ted Baxter: Molenoid Sedo and the King of Sling are opposite versions - King is reformed eventually, but Sedo is working for Blakk.
  • Tempting Fate: Invoked and lampshaded in "The Undertow".
  • Testosterone Poisoning: "The Slug Run". "Sunday Sunday SUNDAY!!!"
  • Theme Music Power-Up: Sometimes done with the ED rather than the OP like most cases.
  • Theme Twin Naming: Brothers Locke and Lode.
  • Third-Person Person: Pronto.
  • Title Drop: In the episode Bandoleer of Brothers, Eli says the episode title at the end of the episode.
    • Also happens early on in "The World Beneath Our Feet".
    • Combined with Call Back in "Keys to the Kingdom" when Pronto drops the title of the episode the Ted Baxter Molenoid first appeared in ("The Slug Run").
  • Too Many Halves: According to Pronto, the Lightwell is "50% legend, 50% lore, and 50% mystery."
  • Tournament Arc: Not really an arc, but the two part series premiere follows Eli through a tournament as he gets a hang of slugslinging and gathers a variety of new slugs.
  • Translator Collar: Eli found that the device that was in a chest could have the listener speak to the Shadow Clan. However, it causes great mental pain to do so. The head of the Clan even said that most can't handle it, though he hinted that Eli might someday.
    • Eli seems to be getting better at handling it, he has used it several times since his first time and hasn’t shown as much strain.
  • Trick Arrow: Having a variety of slugs in your arsenal helps with strategy; punching, net launcher, bolas, taser, smoke cloud...
  • Unknown Rival: Pronto is this to fellow Molenoid Sedo; Pronto has met him before, but Sedo doesn't even recognize him.
  • Unorthodox Reload: Diablos simply slams his blaster on his own bandolier to load a cartridge. So does Boss Ember, except his shells are all on his back.
  • Vampiric Draining: One episode has a Dark Bane monster that feeds off the energy of slugs and humans to stay in Slugterra.
  • Victory Is Boring: The villain in Roboslugs briefly complains about this after his Humongous Mecha defeats Eli and friends.
    What's the point of winning if there's nobody to lord it over?
  • Villain Team-Up: Blakk and the Dark Bane have been working together all along.
  • Water Is Air: Averted with slug-slinging. Slug-slinging is still possible underwater, but unless you have a slug suited for water, you need a torpedo tube for them to gain enough speed to transform. Fire-typed like Burpy are ineffective in an underwater environment.
  • The Watson: Because Eli grew up on the surface and not on Slugterra, what is common knowledge for other characters is not something he could be expected to know and he would need an explanation from his friends. This includes the caverns dying if the slugs abandon it and notable baddies his dad took on, like Blite.
    • Inverted when the gang learn from Eli that the surface world is real. They don't really understand the astrophysics that would explain the Sun or how the Moon would stay in the sky.
  • Wax On, Wax Off: Played straight in "Mario Bravado" when Eli has to master the ultimate trick shot... by working a pizza place. Granted it's a pizza place that involves slugslinging for ultra-fast preparation time.
  • Weak, but Skilled: Unlike the Shanes, Blakk was never an exceptional slinger but made up for it via his innovative tendencies.
  • Wham Episode: “Back to Blakk”. In it we learn Blakk’s origins, how Burpy came to be with Eli’s dad (he used to be one of Blakk’s slugs, but he knocked his cartridge out of place so Blakk couldn't fire at Will Shane, allowing will to get Blakk’s slugs to defect, saying that no slug would ever aid him again), and what led Blakk to create the Ghouls.
    • In the end, Blakk is rescued by Nacho, who used the Gattler to create a portal to the Deep Caverns and release four Dark Bane with him!
  • What Happened to the Mouse?: Several loose ends are left after the series finale. For example:
    • What precisely happened to Will Shane?
    • What is the Game Master going to do?
