The main character. At first an ordinary eleven-year-old kid living in New York City, he discovers the Underland when he follows his baby sister down a vent in their apartment building's laundry room and learns he's the prophesied Warrior.
  • A Boy and His X: At the end of Gregor the Overlander, he bonds with the bat Ares.
  • Badass Normal
  • Because Destiny Says So: If it weren't for the prophecies, he would not be involved in any of the Underland's battles. And he isn't always happy about it.
  • Beginner's Luck: He seems to get lucky a lot when fighting, even though he's not the brightest.
    • Somewhat justified in that he's a rager.
    • Lampshaded in Gregor and the Code of Claw, when he realizes that if his rager skills fail him, he's just a twelve-year-old kid who's had a few sword lessons, and therefore in big trouble.
  • The Berserker: In Gregor and the Prophecy of Bane, he learns he's a "rager" a person with highly developed warrior skills, a natural-born killer. Meaning he has a natural capacity to go into this state when his life is in danger. It's not always voluntary, which is really bad for a character who normally hates to kill.
  • Blessed with Suck: Turns out being the Warrior of the prophecy isn't much fun for him. At the end of the series, he is warned that with his rager abilities it will be much easier for him to kill people, so he'll always have to keep an eye on himself.
  • The Call Knows Where You Live: He never wants to fulfill the prophecies that Sandwich set down for him, but they always find a way to rope him in. Particularly in Gregor and the Curse of the Warmbloods, his Grandma tells him "You can run away, but the prophecy will find you somehow." A bit later his mother is infected with a deadly plague forcing him to go after the cure. The call metaphorically hits him right where he lives.
    • Ripred's "escort" for him is a much more literal example from the same book.
  • Children Forced to Kill
  • Covered with Scars: By the end he's racked up an impressive total. After his fight with the Bane, he basically gives up the idea of even coming up with an excuse for them.
  • Dark Is Not Evil: He wears black armour during the final battle, and his bond is black as well.
  • Death Is Such an Odd Thing: The Kill 'em All ending leaves him in a state of emotional distress about many characters, many of whom were absolute jerkasses toward him. Particularly in Gregor and the Code of Claw, when faced with the Prophecy of Time that foretells his own death.
  • Disappeared Dad: His father in Gregor the Overlander, vanished when he was eight. They find him though.
  • Everything's Better with Spinning: Eventually like Ripred, he learns to spin. It is implied that all ragers can.
  • First-Name Basis: His last name is never mentioned.
  • Heroic B.S.O.D.: Suffers from one in the Gregor and The Code of Claw, when the realization that if the prophecy is true he's going to die.
  • Hyper Awareness: He can see his surroundings by using echolocation.
  • Idiot Hero: He's just a kid, after all.
  • It Sucks to Be the Chosen One: He has a bad case of this. He's fated to fulfill several prophecies which make the series go from mildly darker than standard High Fantasy to bad. Really bad.
  • Kid Hero
  • Missing Mom: When his mom gets the plague in Gregor and the Curse of the Warmbloods, she spends most of the rest of the series recuperating in the Underland.
  • Official Couple: With Luxa.
  • One-Man Army
  • Promotion to Parent: With his dad missing, his mom working, and his grandma's dementia, he starts out with a lot of weight on his shoulders. Things don't get much better when he has the Underland to think about as well.
  • Scars Are Forever: Which he realizes is part of his Bittersweet Ending.
  • Shell-Shocked Veteran: At the end of the series. He's twelve.
  • Star-Crossed Lovers: It's strongly implied that he will never see Luxa again.
  • Unstoppable Rage: As a result of being a rager.
  • War Is Hell: He realizes this is true for both the Underland and Overland in the ending chapter.
  • Well, Excuse Me, Princess!: He seems to love mocking Luxa's stiff conduct and all that. Has some pretty funny moments.
  • Wise Beyond Their Years: Even before the books start, he didn't get to be much of a kid.
  • You Can't Fight Fate: Brought home in Gregor and the Curse of The Warmbloods when his mom contracts the plague; he acknowledges mentally that there was no other way to ensure the prophecy would happen the way it needed to.
  • Your Days Are Numbered: The final prophecy in Gregor and the Code of Claw refers to the Warrior's death.


Gregor's youngest sister. Her real name is Margaret. She starts the events of the whole series by falling through a vent in her apartment's laundry room.


Gregor's second younger sister. Extremely shy, she never even visits the Underland until the last book.

Gregor, Boots and Lizzie's Family

At the start of the series, their father has been missing for over two years.
  • Adults Are Useless: The parents are not completely useless, and never by choice, but they are rarely able to help Gregor with his unique problems. Averted in Gregor the Overlander when the dad manages to steer them back to Regalia.
  • Disappeared Dad: The father in Gregor the Overlander, vanished when Gregor was eight. They find him though.
  • First-Name Basis: The mother's first name is Grace.
  • Good Parents: Though their father is mysteriously missing in Gregor the Overlander, and their mother is a Missing Mom for most of the last three books.
  • Missing Mom: When the mom gets the plague in Gregor and the Curse of the Warmbloods, she spends most of the rest of the series recuperating in the Underland.
  • No Name Given: We never learn the father's name.
  • Shipper on Deck: The mom who secretly approves of Luxa, because she's "got attitude."

Mrs. Cormaci

An older widow who lives in the same apartment building as Gregor's family.
  • Maybe Magic, Maybe Mundane: She tends to send just the right objects at just the right times and who gives tarot readings. Gregor at one point wonders if she can see what he needs in her tarot cards, and given that psychics exist in this series, he could be right.
  • Nosy Neighbor: A well-intentioned and not especially annoying version, but any questions are awkward when you don't know have a good explanation.
  • Secret Keeper: Becomes this for the family starting in Gregor and the Marks of Secret.
  • Supreme Chef: Apparently a very good chef.


Underland Creatures

Tropes that apply to a species as a whole.
  • Aerith and Bob: The humans have both typical English names — Henry, Howard, York, Susanna, Judith — and more fantastic names like Solovet, Nerissa, Vikus and Mareth. Lampshaded when Gregor is introduced to Henry, he almost laughs that "among all these strange names, there's a Henry".
  • Always Chaotic Evil: Most rats and humans believe this about each other.
  • Animals Not to Scale: All of the animals are much, much larger than their Overland cousins.
  • Bat out of Hell: Averted, as the bats are the humans' most valuable allies.
  • Bond Creatures: The humans and the bats are the only species with this. Until Gregor and the Code of Claw.
  • Call a Rabbit a "Smeerp": The assorted oversized creatures of the overworld are given simpler names, allegedly by the people who live there. (Rats are known as "gnawers", spiders as "spinners", and so on.) This is what the creatures of the Underworld actually call themselves, just translated into the nearest thing in English. Humans have one of these names too among the Underworld creaturesnote , but they don't like to hear it.
  • Deadpan Snarker: Seems to be an inborn trait of the rats, who are also some of the few underlanders to use informal language.
    Twitchtip: (when Photos-glow-glow "can't understand" boots): Allow me to translate. She said If you don't stop you incessant bable that big rat sitting in the boat next to you will rip you head off.
  • Dirty Coward: The fireflies.
  • Don't You Dare Pity Me!: And how. All the rats seem to be like this.
  • Evil Albino: This could also apply to some of the humans in the series, but every single Underland human is a violet-eyed albino and a majority of them aren't that despicable.
  • Evolutionary Stasis: Averted in that the Underlander humans' eyes turned purple and their hair turned a very light blond. Although how living under ground could cause a change in melanin levels that quickly could be an example of artistic license.
  • Fantastic Racism:
    • Even though the crawlers/cockroaches, gnawers/rats, spinners/spiders, fliers/bats, etc. that coexist with humans in the Underland are not human, they are sentient and treated as full characters on the same level as humans. Prejudices held among human characters towards these species are even treated as equal to any intra-human bigotry.
    • The bats, humans, and mice are allies with each other, and hate the rats, who hate just about everyone but especially the humans and mice. The insects pretty much hate all the mammals. The spiders are willing to play both sides, and the cockroaches are considered stupid.
  • Good with Numbers: The mice, judging by their Theme Naming.
  • Heroic Albino: Any heroic Underland human is this by default.
  • Humans Kill Wantonly: The giant, intelligent rats are called "Gnawers", bats are "Flyers", mice are "Nibblers", etc. Humans are " Killers", a moniker they picked up after they nearly drove a population of moles to extinction in order to take their land. Not that anyone would call them that to their faces, of course.
  • Lazy Bum: The fireflies. Mareth describes how he once saw two fireflies try to fight to the death over a piece of cake, only to accuse the other of cheating and resort to sulking.
  • Names to Run Away from Really Fast: Ripred, The Bane (whose true name is Pearlpelt), Twirltongue, Lapblood, Mange...all the rats have some scary names.
  • The Nose Knows: The rats demonstrate this quality in their first appearance by accurately calculating what Gragor and Boots ate for dinner hours earlier right down to the tiny bowl of greens. They also are shown to be able to estimate human emotions and navigate and fight in complete darkness.
  • Not So Different: The rats and the humans.
  • Old Shame: invoked In Gregor and the Code of Claw, it's revealed that Bartholomew of Sandwich resorted to poisoning the moles to get their land. It was thought they were all killed by this tactic, and it poisoned everyone else's opinion of the humans.
  • People Of Hair Colour: All the Regalians have silver/blond hair.
  • Purple Eyes: Underland humans are basically a race of albinos, so this trope is justified here.
  • Rat Men: The giant rats, which are sentient. There are similar giant versions of many small animals from our world.
  • Rodents of Unusual Size
  • Spider Swarm: There's a species of spiders called "Spinners" living as an entire race.
  • Strange-Syntax Speaker: The cockroaches tend to mix up verb and subject placement as well as using repetition of certain sentence elements, such as "Do it, I can, do it," or "be small Human, be?"
  • Talking Animal: All of them.
  • Teeth-Clenched Teamwork: If two or more species have to work together, it most likely involves this.
  • Theme Naming:
    • All of the bats have names taken from Greek mythology.
    • Luxa's mother is named Judith, while Judith's twin is named Hamnet and their sister is named Susannah. William Shakespeare had a daughter named Susannah and twins named Judith and Hamnet.
    • The mice are named after famous mathematicians and mathematical principles.
    • The rats have compound names, usually violent — Ripred, Gorger, Makemince.
  • You Dirty Rat: Played straight at first, then subverted big-time.
