Season 1
Red Mantis
Voiced by: Dee Bradley Baker
A large predatory insect that was stalking Anne prior to her meeting Sprig.
- Always a Bigger Fish: A smaller green mantis attacks the Wartwood Amphibians, only to run away after the Red Mantis makes its presence known.
- An Arm and a Leg: It loses its right arm when the portal closes around it after it tries to eat Sprig.
- Big Creepy-Crawlies: It's one of many large insects that live in Amphibia.
- The Bus Came Back: It (or rather another member of its species) makes an appearance in "Escape to Amphibia", being lured to Earth to keep Mr. X and his men busy.
- The Dreaded: Another mantis flees upon sighting it.
- Irony: It's a predatory monster... that is last seen being pulled back to Wartwood, with one denizen suggesting eating it with butter.
- Small Role, Big Impact: It hunts after Anne, bringing her near Wartwood, where she meets Sprig and begins their friendship.
- Starter Villain: It's the first monster that Anne and the Plantar family do battle with.
- What Happened to the Mouse?: After coming to Earth and getting subdued, we never learn what Mr. X had done to the other Red Mantis.
Domino 2
A "coastal kill-a-pillar" whom Anne briefly adopts for an episode. Although she's absolutely adorable, her species' name is unfortunately not a misnomer...
- Ambiguous Gender: Domino doesn't have any particular characteristics that could define it as any gender. The characters consistently use she/her pronouns for Domino, though. The ambiguity is put to rest in the season 3 episode "Fight or Flight", where it is revealed that Domimo 2 is female, since she's taking care of a litter of her kitten-pillars.
- Androcles' Lion: Being saved from being devoured by a pair of wasps and later being saved from Andrias' camp convinces Domino 2 to listen to Anne enough to stop being a threat to the Plantars and their friends, and to boot becoming great allies as the Resistance's aerial cavalry against Andrias.
- Cats Are Mean: She's not an actual cat, she merely resembles one, but she plays the trope straight after metamorphosing into her final form, at least against Amphibians, as she doesn't goes after Anne. In her return, this behavior is lessened when Anne manages to reunite with and tame her, eventually getting her to lead the pack she's the alpha of into becoming the Resistance's aerial support, while her kittens are taken in to be cared for by the frogs of Wartwood.
- Cuteness Proximity: See the picture above, and squeal. Now see the picture below, and be prepared to run as fast as you can if you're an Amphibian.
- Foreshadowing: What's the first thing Domino 2 does to Sprig? She licks him.
- Heel–Face Turn: She goes from attacking the Plantars without hesitation in her debut episode out of predatory hunger before being driven off to becoming an ally of the Rebellion in "Fight or Flight" after reuniting and remembering Anne, followed by being rescued from captivity in Andrias' camp. She promptly gets the rest of her kind that were in her pack to join her in helping out the resistance with their aerial strength.
- Killer Rabbit: Although she's absolutely adorable, her species is known to eat frogs. Even before her metamorphosis, she's shown nibbling on Sprig's leg.
- Mix-and-Match Critters: She's one between a caterpillar and cat in larval form, and a moth and cat in adult form.
- Monster Is a Mommy: She's revealed to be a mother in her return in season 3 when Anne and co. find her nest after she gets captured by Andrias' forces and forced into captive slavery.
- Monster of the Week: Of "The Domino Effect".
- Moth Menace: Her fully grown form is a moth which threatens to eat the Plantar family (but not Anne). Season 3 sees her change from being a threat to the Plantars and all frogs to instead now becoming their ally, remaining a threat only to Andrias' forces.
- Names to Run Away from Really Fast: Her species' name is "Coastal Killapillar", indicating her killer nature.
- Numbered Sequel: It's right in Domino 2's name.
- Pupating Peril: After Hop-Pop reveals that Domino is really a "Coastal Killapillar", Domino 2 creates a chrysalis around herself, emerging soon after as a monstrous moth-like creature that tries to eat the Plantars.
- Replacement Goldfish: For the original Domino, Anne's pet back on Earth, at least until she grows up and tries to eat the Plantars.
- Ridiculously Cute Critter: Anne can't help but fawn over and adore the caterpillar Domino 2. Even after she grows up, Anne finds her cute as buttons when she remembers her, and in turn fawns over her babies, who are just as cute as their mother was in her infancy.
- Roar Before Beating: When menacing the Plantars, Domino 2 lets out the shrieking roar sound effect used by the Cleric Beast from Bloodborne.
- To Serve Man: Domino 2 eats amphibians, and grows to become a danger to every member of the Plantar family. However, she's one of the few giant carnivores that doesn't try to eat Anne, which proves key when she returns in season 3 and recognizes Anne enough to eventually be tamed and stop trying to eat the Plantars and Amphibians in general.Hop Pop: That's a Coastal Killapillar! They're dangerous amphibivores!
- Tuckerization: Both Dominos are named for Matt Braly's own Real Life cat, also named Domino.
- Visual Pun: Cat-erpillar, of course. She's an insect with many feline behavioral traits.
"Mudmen" Cannibal Frogs
"Man, all I wanted to do was get muddy and eat people!"
Voiced by: Bill Farmer
A gang of frog-eating frogs that dwell in the wilds somewhere outside Camp Phlegminton. They cover themselves in mud, attack other frogs, and eat them.
- Cannibal Clan: They eat other frogs.
- Covered in Gunge: They cake themselves in so much mud that they look like they're Muck Monsters.
- Dirty Coward: An almost literal example, in that they cover themselves in mud so their victims are too terrified to fight back. When the mud is removed, they run away.
- Don't Go Into the Woods: The scary story Soggy Joe tells Anne and the Plantars explicitly warns them about these guys.
- Eats Babies: Hinted at with all the "tadpole buckets◊" that Polly spots near the area where they attack the Plantars.
- Improvised Weapon: They're armed with axes, sickles, hedge clippers, and forks and knives. They also fling mud off their own bodies to extinguish torches.
- Monster of the Week: Of "Anne Vs. Wild".
- Nerd in Evil's Helmet: When their gunk is cleaned off, they look unimpressive and flee in fear.
- Weaksauce Weakness: Anything that'll clean their mud off.
The Herons
- Attack of the 50-Foot Whatever: They are taller than the Southern Toad Tower and can ravage it with ease.
- The Dreaded: They strike fear in the hearts of Amphibians, the Plantars most especially.
- Giant Flyer: Being a pair of giant murderous birds, it's a given.
- Giant Equals Invincible: They’re good as immune to Earth’s weaponry, taking no damage from Mr. X’s experimental laser guns and blowing away tank shells with a flap of their wings. Oddly though, they were scarred by a simple spear.
- Heel–Face Brainwashing: The Plantars use their sacred hunting dance to hypnotize the Wartwood herons and turn them to their side.
- Know When to Fold 'Em: They immediately flee the moment Grime and Sasha manage to fight back against them.
- Knight of Cerebus: The tone always shifts to be a bit darker whenever they're on screen.
- Starter Villain: They are the first challenge Sasha conquers.
- What Happened to the Mouse?: They’re last seen in Los Angeles helping clean up the damage from Andrias’s invasion. There’s no word on if they were returned to Amphibia or kept someplace on Earth.
- You Killed My Father: A pair of herons killed Sprig and Polly's parents when they were young. The same pair is later used by Andrias and Darcy as living weapons for their invasion, allowing the Plantars to finally get their revenge.
Jonah
"This is incredible! I've been searching for Sadie for thirty years!"
Voiced by: Jeff Bergman
An old enemy of Mrs. Croaker.
- Accidental Pervert: Mrs. Croaker calls him one after he unintentionally flashes his belly at her while taking out another weapon.
- Arch-Enemy: To Mrs. Croaker. He's wanted to kill her for 30 years.
- Best Served Cold: He's trying to kill Mrs. Croaker for something that happened over 30 years ago.
- I Was Quite a Looker: Like Mrs. Croaker herself, he was a lot better-looking in his youth.
- Mad Eye: His left eye is larger and has a visible red iris, which his right eye lacks, to emphasize his unhinged personality.
- Noodle Incident: Jonah mentions how he'll be able to return to a certain guild once he finishes off Sadie.
- Old Flame: Sprig believes he is this to Mrs. Croaker, but actually he's her Arch-Enemy.
- Red Eyes, Take Warning: The pupil of his left eye notably turns red when he attempts to kill Mrs. Croaker.
- Retired Badass: He's an old hermit who seems to have been an enforcer or assassin of some kind in the past.
- Yellow Eyes of Sneakiness: Jonah's eyes are a pale yellow, and he pretends to be friendly to get what he wants.
Dandy Lion Innkeepers
Teddy: What can a legless little tadpole like you do to stop us? (from left to right: Juniper, Teddy, Martha, and Juliet.)
Voiced by: Chris Sullivan (Teddy), Kari Wahlgren (Martha, Juniper, and Juliet)
A cannibalistic family of horned bullfrogs who prey upon travelers looking for lodgings. Teddy and Martha are the married couple who own the Dandy Lion Inn. Juniper and Juliet are a set of sisters (it's never specified whether they're Teddy's biological sisters or Martha's) who might or might not also help run the inn... but definitely help eat its guests.
- Adjective Animal Alehouse: The bed and breakfast they run is called "Dandy Lion Inn".
- Bad People Abuse Animals: They may not eat the snails, but their stables are filled with ones that belonged to their previous victims — and every single one of them has a bear trap equivalent latched onto their tails like Bessie did, presumably never removed so they don't escape or help someone else escape, which would have to be a constant source of pain for them.
- Cannibal Clan: They eat other frogs (which is Truth in Television for their species).
- Creepy Twins: Jennifer and Julia are all but stated to be twins, and they definitely have had a hand in eating unsuspecting guests.
- Eats Babies: They would have eaten Polly too!
- Even Evil Has Loved Ones: They're one big, happy, loving family of fellow-frog-eating psychopaths.
- Evil Old Folks: All four of them are around Hop Pop's age.
- The Family That Slays Together: They've eaten LOTS of other guests before the Plantars came.
- Faux Affably Evil: Teddy and Martha are the very picture of warmth and hospitality when welcoming guests into their inn. It's just a ruse to lure victims into their inn so they can eat them.
- Inn of No Return: Their bed and breakfast is this.
- Sapient Eat Sapient: Beside eating frogs, they're also willing to put Anne on their menu. Oddly, they don't seem to be interested in eating snails at all, keeping a whole herd of them belonging to all their former victims.
- Serial Killer: They have a stable full of snails, showing that they've been getting away with killing and eating other frogs for a long time.
- Uncertain Doom: Anne blows up their inn, and it's unclear if the family survives the explosion.
- Unholy Matrimony: Teddy and Martha, who dote on each other.
Barry
"Surely you remember barging into me at the market yesterday?"
Voiced by: Keith Silverstein
A seemingly jolly merchant who runs a stand that sells berries and candies called "Barry's Berries," who is also secretly a magic user. Sprig and Anne get on his bad side when they accidentally bump into him while he's carrying a bunch of rare blue moon berries, which only grow once a decade.
- Bitch in Sheep's Clothing: He presents a friendly façade to the town for the sake of his business, but secretly he's petty, vengeful, unforgiving, and willing to use the dark arts against people who've angered him.
- Black Magic: Barry's a magic user, who casts transformative curses on people he dislikes.
- The Bus Came Back: He returns in season 3 as the ringleader of the Marauders during the apocalypse era.
- Disproportionate Retribution: He curses Anne and Sprig because they accidentally cause him to spill the berries he was carrying.
- Evil Is Petty: Self-admitted.Barry: I may look nice, but I'm petty and vengeful on the inside.
- Hate Sink: Barry is one of the few sapient villains in the series who isn't given any comedic quirks, sympathetic motives, or redeeming qualities. He has no issue cursing children for a minor mistake they made, and refuses to forgive them and lift the curses after they apologize to him. He also doesn't mind screwing over the resistance as the leader of the Marauders just to save his own skin, not caring about the damage Andrias and his army are doing to Amphibia. It makes his potential fate of being cooked and eaten by his Marauders much more fitting.
- Hidden Disdain Reveal: He reveals how much he actually resented being bumped into and losing his berries when Sprig, Anne, and Maddie track him down to his secret storage shed.Barry: I played it cool and was sweet, because my image is half my business!
- Hoist by His Own Petard: Maddie ends up defeating him by catching one of his curses, combining it with feathers from Anne and hair from Sprig, and then throwing it at him, causing him to turn into an amalgam of what he turned Anne and Sprig into.
- Laser-Guided Karma: Not only does he end up transformed into a combined version of what he turned Anne and Sprig into, but his battle with Maddie used up all the curse supplies in his secret shack, meaning he won't be able to indulge in any future acts of petty revenge for a while. Not only that, but a lot of his candy supplies were destroyed in the crossfire, and he's forced to give Maddie three crates worth of the remainder in return for her uncursing him.
- Shout-Out: Fittingly for a candy seller, he dresses like Willy Wonka, and his voice is inspired by Ed Wynn, much like King Candy.
- Slave to PR: He hides his darker nature behind a cheery front, because his image is half his business.
- Uncertain Doom: He's implied to get eaten by his own band of marauders after the Wartwood Resistance defeats them and destroys their supplies.Barry: (as his band closes in on him drooling with forks and knives) Holy (clucks)!
- Villain with Good Publicity: Publicly, he presents an image of irrepressible cheerfulness.
Tritonio Espada
"Give my regards... to the guards!"
Voiced by: Matt Chapman
The new head of the local daycare following the retirement of the Bogwaters, having converted it into a combat training camp for kids. In reality, he's a train robber who's been training children to rob trains for him.
- Affably Evil: He's affable enough to be the first teacher Anne honestly likes. He may con and backstab the kids to have them take the fall for his crimes, but he admits to himself that he genuinely liked them and that it's a shame they'll be locked up forever. He also shows remarkable grace when Anne defeats him, even though it leads to his arrest.Polly: Where's old "teachers stink" Anne?
Anne: THAT ANNE IS DEAD AND BURIED. - Badass Teacher: True, he's teaching children to rob trains, but it's under the pretense of giving them proper combat training. And when push comes to shove, he is still a force to be reckoned with.
- Beard of Evil: He has a goatee, but it's revealed to be fake.
- The Bus Came Back: He returns in "Newts in Tights."
- Carpet of Virility: He has visible chest hair. Despite being a newt.
- Con Man: First, he cons Hop Pop into thinking he's just the stern new head of the local daycare, and then he cons Anne, Sprig, and Polly into thinking he's really a Cool Teacher who wants to teach them combat to survive in the world. It turns out he's actually a thief who manipulates children into helping him with his heists, then leaves them to take the fall.
- Cool Teacher: He may be a crook who betrays the Plantars, but his lessons and advice are legitimately useful, and Anne, Sprig, and Polly all come to respect him.
- Dashing Hispanic: He's a skilled, stylishly-dressed fighting instructor with a Spanish accent and surname. Subverted when he turns out to be a con man, if an Affably Evil one.
- Family-Friendly Firearms: A variant. He uses a fencing rapier, presumably so he won't actually harm his students. Ironically, he gives Anne a sword with sharp edges.
- Freudian Excuse: As a child, he was alone on the streets of Newtopia. He was taken in by a gang of other orphans, but was left to take the fall for one of their crimes, and imprisoned. This led him to believe he had to betray others in order to survive. Anne is not particularily convinced.
- Graceful Loser: He is impressed when Anne manages to defeat him, and doesn't seem to hold any ill will towards her for getting him sent to prison.
- Heel–Face Turn: In "Newts in Tights", he is convinced by Anne to rescue the little band he raised himself from being murdered by King Andrias' forces, and also joins the resistance as their lead strategist.
- Master Swordsman: He's a skilled duelist, and Anne can't get the better of him in a straight-up fight even after being trained by him. She ends up defeating him by blinding him with sunlight as a distraction.
- Meaningful Name: "Triton" is an old word for newt, and is still used in some languages, such as Greek. "Espada" is Spanish for "sword."
- Shout-Out:
- Tritonio's outfit and his accent are highly reminiscent of Inigo Montoya from The Princess Bride.
- When he reappears in season 3, he's a dead ringer for Robin Hood in both his outfit as well as his newfound group of newts that act as his "Merry Men".
- Small Role, Big Impact: Tritonio only appears in a single episode in the first two seasons, but by teaching Anne how to fight, he does Wartwood and all of Amphibia a huge long-term favor. Compare Anne's struggle against the three toads in "Toad Tax" to her victory over Sasha in "Reunion".
- Stern Teacher: To begin with, it's strictly towards Anne, though he explains to her that it's mainly because he sees potential within her to do better than she initially does, and he imagines her teachers at home are the same way. For all his deceitful ways, he does change Anne's perspective towards the end.
- Wisdom from the Gutter: He tells Anne that he sees the potential in her to eclipse him as a sword fighter, justifying why he is so hard on her. This is what gets Anne to try harder and decide she is going to give her teachers back on Earth another chance.
- Worthy Opponent: He seems to view Anne as this after she defeats him and he's led away to prison.
Apothecary Gary
"Just rub a little of this on their foreheads, and your kids will be behaving in a jiffy!"
Click here to see Gary's true form
Voiced by: Tony Hale
A mysterious frog who gives away potions he makes for free. His true form is that of a giant mushroom controlling the frog whose head he's attached to.
- Actor Allusion: Gary shares his name with one of Tony Hale's most well-known roles, Gary from Veep. Though, Gary is the name of the mushroom, not the frog it's controlling, whose name is Lloyd.
- Affably Evil: He's able to hold casual conversations with Hop Pop even after revealing his true self.
- Ambiguous Situation: It's never made clear if Gary's species is native to Amphibia or if they were brought there from another dimension conquered by the Leviathans.
- Beard of Evil: He has a small tuft of beard on his chin. Although, the frog who actually has the beard isn't evil, just mind-controlled by the mushroom.
- The Bus Came Back: He returns in season 3 as the leader of the plant-loving town Gardington.
- Enemy Mine: He's willing to join the Resistance despite his history with Hop Pop in order to be safe from the threat of King Andrias.
- Fungus Humongous: The mushroom is about the same size as the frog controlled by it.
- Glowing Eyes of Doom: The frog has purple, glowing eyes, showing that he's under the mushroom's control.
- Heel–Face Brainwashing: As Andrias is using his species to mind control his minions, Gary can override the spores controlling the subject to force them into aiding the heroes.
- Heel–Face Return: In his second appearance, Gary reveals that he has formed a genuinely beneficial relationship with a community of frogs. While they still want revenge on Hop Pop, by the end of the episode they join the cause against Andrias.
- Hidden Depths: He's a surprisingly good botanist and farmer, able to turn a barren wasteland into a bountiful garden. This is Truth in Television, as fungi can form mutualistic relationships with plants through their mycorrhiza.
- Just Desserts: He and his spores end up getting eaten by Bessie, since mushrooms are her favorite treats.
- Last of His Kind: Gary pleads that Hop Pop not feed him to Bessie, since he's the last of his kind and his species will die out. Since Gary had just tried to mentally enslave everyone in Wartwood, Hop Pop's okay with that. However, the end shows that Gary's kind might not be gone for good.
- Possibly subverted, as "Root of Evil" suggests that Andrias is using another one of Gary's species to make mind control collars. Gary is ecstatic to hear this, and he wants to save that mushroom as soon as possible.
- May Contain Evil: Gary's potion contains mind-control spores.
- Mind-Control Eyes: Everyone infected by the mushroom gets purple, glowing eyes.
- Monster of the Week: Of "Children of the Spore".
- My Eyes Are Up Here: A rare non-sexual, male example. He says this nearly verbatim to Hop Pop when he reveals his true form to get him to pay attention to the mushroom, not the frog he's controlling when he talks.Gary: Also, eyes up here, buddy. (points towards the mushroom)
Hop Pop: Oh, uh, sorry. It's just, you're glowing, he's got the mouth—
Gary: I know, right? It's totally weird. I completely get it. - Not Me This Time: King Andrias has been using mind-control devices on the local wildlife which work by infecting them with mind-control spores like what Gary uses. Gary doesn't know how that's possible, but they're definitely not his, and that piques his curiosity.
- Portmanteau: Apothecary Gary tells Hop Pop that he's also welcome to call him "Apothegary."
- Puppeteer Parasite: "Gary" is actually the mushroom atop the frog's head.
- Tom the Dark Lord: A mind-controlling fungus named Gary. He's not just using the name of the frog he's been controlling, either — the frog's name is Lloyd, by the way.
Season 2
The Hasselback Gang
Judro: Whoo-whee! You done asked for it, so here it comes — this here's the Hasselback Gang! (clockwise from top: Mama Hasselback, Ruth, Talbert, Judro, and Heathro.)
Voiced by: Jenifer Lewis (Mama Hasselback), Keith Ferguson (Judro Hasselback, Talbert Hasselback, & Heathro Hasselback), Eden Riegel (Ruth Hasselback)
A gang of outlaws that have been terrorizing the town of Bittyburg until the Plantar family comes along.
- Bandit Clan: They're a family of outlaws extorting money from the diminutive citizens of Bittyburg.
- Family-Unfriendly Death: The moment the tiny citizens start fighting back, the gang is practically torn apart, with Mama Hasselback even having the little frogs burst through her chest.
- Deep South: Where the gang comes from. They all have thick Southern accents and don cowboy attire to boot.
- Exotic Eye Designs: Heathro has red pupils that look like plus signs.
- Eyepatch of Power: Judro sports one as part of his outlaw appearance.
- Large and in Charge: Mama Hasselback is the largest member of the gang.
- Laser-Guided Karma: They end up getting swarmed and overwhelmed by the very frogs they once terrorised.
- Non-Human Humanoid Hybrid: Judro introduces Ruth as his half-sister, but she has distinctly newt-like features despite her brothers and mother being pureblooded toads, implying she's a toad/newt hybrid.
- The Quiet One: Ruth and Heathro don't speak much, save for a single line each, and all Talbert gets is a yell.
- Rolling Pin of Doom: Mama Hasselback's weapon of choice is an enormous rolling pin.
Renee Frodgers
"Renee Frodgers's the name and managing this acting troupe is my game!"
Voiced by: Susan Egan
A theater director who leads a traveling theater to perform in towns, but there's more to her than meets the eye.
- Affably Evil: She's friendly and encouraging to Hop-Pop when they first meet. She's also completely upfront to Hop Pop that the whole thing is a sham to rob a bank.
- Broken Pedestal: Upon finding out she is the one who wrote his favorite play, Hopediah is ecstatic to meet Renee. This all changes when he finds out that she plans to use his acting to distract a town so she can rob a bank.
- Evil Is Petty: She robs towns out of resentment for the lack of audiences her shows get.
- Film Felons: Her acting troupe uses their plays as distractions while she steals from the towns they visit.
- Irony: She first appears using her caravan to save the Plantars from a Sand Worm, telling them that having multiple cars makes them look like another predator that the worm is scared of. While attempting to flee, she detaches her caravan from the other cars, which makes her an easy target for another worm.
- Never My Fault: She claims she only robs towns because of the "lack of culture" in Amphibia these days.
- No Honor Among Thieves: Renee ditches her goons when Hop-Pop outs their planned robbery to their latest would-be victims.
Curator Ponds
"Looks like we just hit pay dirt, Frog Soos!"
Voiced by: Alex Hirsch
The owner of a mysterious shack of oddities, artifacts, and wax sculptures called the Curiosity Hut in the town of Stony Gulch. He bears a heavy resemblance to a certain other Disney-owned curator of a strange tourist trap.
- Adaptational Badass: If he is in fact an alternate version of 'Grunkle Stan', he's one who's managed to capture many dangerous creatures with his wits and a wax machine, a far cry from the one who uses fake attractions or steals real ones that aren't aggressive super-predators. It would be admirable if he also wasn't a whole lot worse than the human version of him ever was.
- Adaptational Villainy: Unlike Stan Pines, he has no redeeming qualities of any kind, and his greed drives him to stoop to lows that not even Stan would sink to.
- Affably Evil: Hilariously enough, he's still the same old Grunkle Stan aside from the "being a murderous fraud" detail. He chats up Anne while he's trying to wax her, offers her some canned meat, and tells her not to get herself down when she beats herself up over falling for his guile. Anne lampshades that this is a weirdly nice thing for him to say.
- Alternate Self: If what Frog Soos says is true, he isn't just a frog that happens to resemble Stan Pines, he is Stan Pines' Amphibian counterpart.
- Corrupted Character Copy: He's based off of "Grunkle" Stan Pines, right down to his voice actor, but Stan would never stoop to levels as low as the Curator does, such as covering creatures in wax to make exhibits out of them, or actively trying to prevent them from being rescued.
- Eyepatch of Power: Just like the man he's based on, he wears one despite having both eyes, and has a habit of switching which eye gets covered, all to add to his mysterious image.
- Greed: Par the course, except it's much worse in his case than Stan's.
- Hope Spot: When dragged by the monsters into a room, a puddle of red liquid pools out that he clarifies is just some wax. However, he still didn't survive the creatures' revenge.
- I Have Many Names: He claims this, and at least one other name for him is known, namely Mr. Ponds.
- Just Desserts: He is killed and probably eaten by the creatures that he had trapped in wax.
- Karmic Death: He's dragged by the many creatures he trapped in wax to a dark room, where they kill him offscreen. There's exactly zero ambiguity about his death unlike most Monster of the Week baddies; even
Word of God confirms he's monster chow. - Obviously Evil: He is so blatantly suspicious that even he is surprised Anne was willing to blindly trust him.
- Pet the Dog: After Anne beats herself up for falling for his trap, he tells her that she's a bright lady and she's just having a bad day.
- Whole-Plot Reference: Aside from being an obvious Expy of Stan, his scheme of encasing interesting creatures he comes across in wax to make exhibits is extremely similar to Stan's behavior in the (non-canon) episode "Little Gift Shop of Horrors", where he glues the viewer's mouth shut and puts them on display as an attraction.
- Would Hurt a Child: He show no hesitation to turn Anne and Sprig into wax figures.
Screen Fiend
A creature that resides in a cursed video, trapping anyone who watches it indefinitely.
- Can't Take Criticism: Or rather, "Gets Killed By Criticism," since anyone disliking its video or leaving a negative comment on it deals physical damage to it.
- Defeat Equals Explosion: After Anna deals the finishing blow, it explodes into numerous boba-like eggs that hatch into more monsters.
- Red Eyes, Take Warning: Its eyes glow red, showcasing the danger it poses.
- Ridiculously Cute Critter: Exploited. Anyone who gets enthralled by its cuteness immediately marks themself as its next target.
- Shout-Out: It's a cute, furry creature with big ears that turns into a horrific monster capable of making more of itself. Did we just describe the monster or the mogwai from Gremlins?
- The Fourth Wall Will Not Protect You: By the time it hops out of its video player into the real world, it's already too late.
- The Power of Hate: How it's defeated.
- Wingding Eyes: Its eyes feature a play button and a pause button.
- Would Hurt a Child: All of its known victims are pre-teens.
Mr. Littlepot
"Hopadiah, please don't make a fuss. I didn't do anything to those frogs. I'm like you, just taking them where they need to go."
Voiced by: George Takei
A mysterious frog that Hop Pop meets while he is telling a story about himself driving Bessie.
- Above Good and Evil: He claims to be this, comparing himself to a ferryman who simply guides frogs meant to die to their final resting place — which almost sways Hop Pop. However, the unmistakably sadistic glee he takes in doing his job implies otherwise.
- Bald of Evil: He is bald underneath his hat, and is a bad guy. Subverted once he steals Hop Pop's hair.
- Big Red Devil: He certainly qualifies, given his red skin, yellow eyes, and goatee.
- Classy Cane: He sports one with a vulture's skull on top. It can also turn into a scythe.
- Dark Is Evil: He dresses entirely in black, is the Grim Reaper of Amphibia, and takes a sadistic pleasure in his job.
- Evil Sounds Deep: He has a deep voice, courtesy of George Takei, and is definitely not the nicest guy around.
- The Grim Reaper: He is the frog version of the Grim Reaper.
- Red and Black and Evil All Over: Red skin, black suit, menacing aura. Hey, at least he's paying.
The Chicka-Lisk
Voiced by: Dee Bradley Baker
A large cockatrice-like creature that Anne and the Plantars summon to destroy their fake presents.
- Basilisk and Cockatrice: It's the Amphibia equivalent of these, as evidenced by its name, chicken-like appearance, and ability to turn people into stone.
- Beware the Silly Ones: It's a giant chicken, but it's also an Eldritch Abomination with a ridiculous array of powers. All of Wartwood ganging up on it just briefly inconveniences it, and it only leaves in the end because it finds their "Chicka-lisk Formation" offensive.
- Blow You Away: Maddie calls it "the storm bearer", and it has the ability to generate tornadoes by flapping its wings.
- Breath Weapon: One of its attacks is its fire breath.
- Early-Bird Cameo: It first appeared in the intro before it ever made it into an episode of the show proper.
- Eldritch Abomination: It's an ancient monster with supernatural powers, can be summoned by "eldritch magic", and is referred to by Hop Pop as an Elder God.
- Eye Beams: It uses these to turn people to stone.
- Feathered Fiend: Downplayed. It's a dangerous feathered creature, but it does not feed on Amphibians, and only attacks when provoked.
- Monster of the Week: Of "Return to Wartwood".
- Non-Malicious Monster: The tome says that it doesn't eat frogs and only attacks when provoked. It is in fact very nice and polite, and only attacks the Wartwood citizens when they threw rocks at it. This is why the Plantars decide to summon it, as it is the safest monster to eat the presents.
- Playing with Fire: It can breathe fire.
- Screw This, I'm Outta Here: It leaves Wartwood after finding the frogs' imitation of it to be offensive.
- Shockwave Stomp: It uses this technique to knock down several of the townsfolk attacking it.
- Taken for Granite: It can turn people to stone with its Eye Beams.
- The Unintelligible: It communicates in shrieks which the villagers cannot understand. The subtitles reveal that it is in fact quite well-spoken.
Season 3
The Marauders
An insidious third faction led by Barry. They wreak havoc wherever they go, indulging in twisted hedonism.
- Bomb-Throwing Anarchists: They revel in the ongoing destruction of Amphibia, as it allows them to release their darkest desires.
- From Nobody to Nightmare: One of the marauders, Brian, admits to having been a humble accountant in the past, but he now takes enjoyment in drinking the blood of his enemies. He also eats dessert for breakfast now.
- I'm a Humanitarian: After Barry is turned into a chicken, the members look at him with the full intention of eating him.
- Square Race, Round Class: Subverted. Brian used to be this trope, being a toad accountant. He now fits the stereotype of toads to a T.
- Take a Third Option: Rather then pledging their allegiance to Andrias or fighting against him with the resistance forces, the Marauders prefer to ransack and pillage ruined towns for the fun of it.
