Calvin

"I'm great because I'm Calvin!"

— "The World's Greatest Calvin"

Debut: Calvin and Hobbes: The Movie

Voiced by: Pamela Segal

The leader of the group. He's invented many weapons and gadgets that are usually of some use. By Season 4 he becomes a lot more manipulative and innovative.

• Adaptational Badass
• All Love Is Unrequited: The focus of this for Maria, much to Andy's dismay.
• Anime Hair: Lampshaded by the narrator in the very first episode:
  "No one knows why his hair does that. Is it static electricity? Is it hair gel? No, probably not.''
• Book Dumb: Lampshaded in "Pharaoh Andrew":
  Hobbes: You know, if you actually studied, you'd get a few things done school-wise.
• Break the Cutie: "Trouble Island" has him breaking down when Retro tricks him into thinking Hobbes isn't real.
• Brilliant, but Lazy: He's invented several amazing objects, later turning into The Chessmaster, and yet still fails at school.
• Captain Crash: Invoked: he makes it a point that the wagon needs to be crashed at least twice each week.
• Captain Obvious: He keeps having to explain things to Hobbes in "The Pharaoh Andrew".
• Character Development: Along with Andy, he's the most blatant example.
• Character Exaggeration: His knack for inventing is much more prominent here.
• Cloud Cuckoolander: While not to an extent like his comic strip counterpart, he still lets his imagination run wild.
• The Chessmaster
• Deadpan Snarker
• Death Glare: Gives one in Nocturnals that the authors says "would've chilled a six-pack".
• Four-Temperament Ensemble: The Choleric.
• Gadgeteer Genius
• Genre Savvy: As shown here:
  Hobbes: (to an evil voice) Well, we're here now, so what do you want?
  Calvin: Hobbes, don't ask questions like that! Don't you ever watch those science fiction movies?
• The Hero

• The Leader: Type III.
• Limited Wardrobe: Parodied: his closet are entirely made of red shirts with black stripes and black pants.
• MacGyvering
• Mr. Exposition
• Mr. Imagination: Rather downplayed in comparison to his comic counterpart.
• Took a Level in Badass: Though he was already an Adaptational Badass, he becomes a lot more serious about dealing with bad guys during Season 4 (seen most prominently in the climax of "Our Solemn Hour").
  • It's suggested in the rewritten Calvin and Hobbes III: Double Trouble that Calvin took a level in reaction to the increasingly dangerous ways his enemies tormented him, forcing him to mature in the way he fought back.
• Took a Level in Kindness: While still something of a Jerkass, this iteration is more prone to doing the right thing.

Hobbes

Debut: Calvin and Hobbes: The Movie

Voiced by: Tom Hanks

Calvin's best friend. Though he's always harbored a reluctance for adventure, here he's gone to straight-up running away from danger, at least until "Thunderstorm".

• Beware the Nice Ones: Gets pretty steamed up to the point of nearly killing Sherman, if it wasn't for Calvin's interference in "Remember." "R.I.P Calvin" and "Thunderstorm" also shows him in a Let's Get Dangerous! mode.
• Character Development: His progression from Lovable Coward to Dirty Coward, and eventually reversed entirely.
• Character Exaggeration: His reluctance for adventure. This is eventually reversed.

• Deadpan Snarker
• Fantastic Racism: He's not fond of lions because they apparently have this (Calvin at one point claimed that lions kicked him out of a club). It didn't help that the lion he met in "That's MISTER Sherman To You!" didn't think much of tigers.
• Four-Temperament Ensemble: The Phlegmatic, along with the MTM.
• Genre Savvy: He knows the outcome of Calvin's constant misadventures.
• Hypocrite: Calvin calls him out on this in "Thunderstorm".
• The Lancer
• Let's Get Dangerous!: Tends to come out in later stories, especially whenever Calvin is in danger.
• Lovable Coward: He's usually this.
  • He started to become more of a Dirty Coward. Word of God says that this was an unintentional Flanderization, as they inadvertently made Hobbes so cowardly he was almost unlikeable. To resolve this, they took Hobbes' cowardice up a notch in the Season 3 finale, until Calvin finally calls him on it with a "The Reason You Suck" Speech, prompting Hobbes to subsequently make an effort that seems to have stuck in the seasons that followed.
• Not-So-Imaginary Friend
• Offscreen Teleportation: His preferred method of cowardice.
• Screw This, I'm Outta Here: Constantly. Played for Drama and/or deconstructed, and downplayed thereafter, in "Thunderstorm".
• Took a Level in Badass: After his unintentional Flanderization in Season 3, Season 4 onwards sees him gradually becoming braver and sticking by the group through dangerous situations, seemingly remembering that he's a tiger and using that in battle.

Socrates

Debut: "Home UnAlone" (from Calvin & Hobbes: The Series)

Voiced by: Ryan Stiles

A tiger who looks exactly like Hobbes, except with red stripes on his tail. He's The Prankster, and his Cloud Cuckoolander personality fits perfectly with it. No one really likes him, though they keep him around and he has his golden-hearted moments.

• A Day in the Limelight: "Confessions of A Prank-Loving Tiger"
• Bad Liar: As "Mission: Socrates" shows.
• Beware the Silly Ones: While "Have You Seen This Tiger" sums this up to an extreme, there are other rare times where he handles things more seriously.
• Break the Cutie: After a tensionful moment "Black Rain". Subverted in "Have You Seen This Tiger" where it's more of a case of Deconstruction and, while he spends a good chunk of the first half as The Berserker, he still reverts back to his usual goofy mood at the end.
• Big Eater: He once made a real-life food pyramid and tried to eat it.
• The Big Guy: Something of a Boisterous Bruiser.
• The Chosen One: The aliens in "Prelude to a Season" heavily imply this.
  "Well, my lord, the ancient texts say the one shall be marked. He or she will hold a unique distinction, setting them apart from the rest of their kind."
• Cloud Cuckoolander: For one, he listens to heavy metal music to fall asleep.
• Comedic Sociopathy: One of his defining character traits.
• Dissonant Serenity: As a part of his status as Cloud Cuckoolander, he handles most of the more dangerous situations with some of the most unusual upbeat cheeriness. This is even Lampshaded during "Pranking The Ghosts" where he immediately switches back to his odd self just mere minutes after being attacked by a ghost! Twice!
  • While Rupert and Earl invaded Earth, took control of every living being there, and turned it into an army base, Socrates has been napping under rubble the whole time.
  • Retro Chill has him calmly reading an alien field guide as Galaxoid and Nebular's ship falls into the lava ocean and the two aliens and Bob are screaming in terror. Especially since he somehow knew the ships were lava proof.
    • This is fazed out later on in the series and in the remakes.
• Distressed Dude: Has been held hostage by Dr. Brainstorm twice for ransom (even though Calvin shows no concern for him at all) and in "Nocturnals" the mist tells him that something is after him. "Black Rain" has him being kidnapped by Thunderstorm and Shadow, and he later gets kidnapped by the Collective in the fic of the same name.
• Four-Temperament Ensemble: The Sanguine.
• The Friend Nobody Likes: He's usually seen as this, though he has his redeeming moments.
• Identical Stranger: Looks exactly like Hobbes, save for the red stripes on his tail.
• In-Series Nickname: "Crateso" from Calvin.
• Jerk with a Heart of Gold: Although he delights in the suffering of others, he does show concern when it seems his pranks may have injured someone.
• Karma Houdini: A Garfield-esque one, though it has been averted every so often.
• Living Macguffin: He has an alien transmitter in his head (implanted by Sherman as revenge for being pranked) that can only be activated when he says the number 98,562.

• Not-So-Imaginary Friend: He takes on a similar form to Hobbes when anybody other than Calvin, Andy or Elliot is around.
• Split-Personality Merge: In The Collective, he fuses with his darker self, having finally realized that the key to controlling his more destructive side was not avoiding it but rather moderating it.

Andy

Debut: Attack of the Teacher Creature^note or, canonically, the rewritten version of Calvin and Hobbes: The Movie

Voiced by: Andrew Lawrence

An eight-year-old boy (named after his voice actor) who starts out with no personality. It doesn't take long for Character Development to kick in, making him the Only Sane Man by the third season. He's also Sherman's owner.

• A Day in the Limelight: "Insanity is In The Air" and "New Year, New Disasters".
• All Love Is Unrequited: His crush on Maria in "Insanity is In The Air".
• Character Development: The most prominent example: he goes from "no personality" to the Only Sane Man over the course of three seasons.
• Deadpan Snarker: Soon became one of his defining character traits.
• Four-Temperament Ensemble: Starts out as the Phlegmatic II before becoming the Leukine.
• The Generic Guy: For a while. Lampshaded in "Insanity is In The Air":
  Hobbes: (discussing why Andy won't come out of his room) Maybe he's hiding something from us.
  Socrates: What would he hide from us? He's not exactly known for having a personality here.
• The Heart: He's the most level-headed person in the group, and thus the one that keeps it together.
• Identical Stranger: He discovers a pharaoh that looks just like him in "Pharaoh Andrew".
• Mistaken for Special Guest: Inverted; he is mistaken by several mummies to be their master (who looks just like him) in "Pharaoh Andrew".
• Nice Guy: The genuinely nice person out of the main cast. Pointed out by Word of God.
• Not So Above It All: "Insanity is In The Air", which also gave him some Character Development.
• Only Sane Man: As mentioned above.
• The Quiet One: Lampshaded by Socrates:
  (trying to find Andy) "Well, [he] was never the talkative one. Admittedly, he's gotten better this season, but...
• The Stoic: The fact that he has no qualms about the fact that Calvin lives with a tiger is only one example of how open-minded he is. In fact, Word of God has said that it's that open-mindedness that allows him to take part in Calvin's adventures.

Sherman J. Hamster

"You know, when I was at the university..."

Debut: Attack of the Teacher Creature

Voiced by: Colin Mochrie

The Smart Guy of the group, an egoistical one at that. Because of this, his status as The Friend Nobody Likes (save Andy, his owner) goes unchallenged until Season 3, where he becomes friends with Calvin. He's still not fond of Hobbes or Socrates, though.

• Afraid of Doctors: Thanks to Hobbes and Socrates' influence in "Sherman Goes to the Vet".
• Bungling Inventor
• Catchphrase: "You know, when I was at the university..."
• Character Development: See Jerk with a Heart of Gold below.
• Deadpan Snarker: From "Pharaoh Andrew":
  "So, Calvin's the Earth Potentate, Hobbes and Socrates are robots and you're a Pharaoh. All together an off day. Time for a nice hot cup of anti-psychotic medication."
• Foil: To the other five members of the group, being a higher-class person surrounded by decidedly uncultured people.
• Four-Temperament Ensemble: The Melancholic.
• The Friend Nobody Likes: At the start of the series.
• Intellectual Animal: Due to working with Andy's dad at a university.
• Jerk with a Heart of Gold: Zig-zagged. He actually cares a great deal for Andy, and he and Calvin become friends later on. Still on bad terms with Hobbes and Socrates, though (partially due to his place in the food chain).
• The Load: During "The Genius Hamster".
• Mix-and-Match Critters: Briefly forced to become one in "Time Terror" to sell... something.
• Mysterious Middle Initial: What does the J stand for?
• Picky Eater: From "The Genius Hamster":
  (asking Hobbes to make him a sandwich) "Now cut the turkey thin, but not too thin. Now put the mustard on the turkey in a clockwise motion, and then place a slab of cheese on top. Pour the mayonnaise on top of that, but in a counterclockwise motion. Add an extra slice of turkey on top, and then place the second slice of bread on top, and make sure the two slices of bread are even."
• Shorter Means Smarter
• Small Name, Big Ego
• Species Surname: According to "The Case of the Rogue Water Balloon".
• The Smart Guy
• Stuff Blowing Up: Often the cause of it.
• TV Genius

The MTM

Debut: Calvin & Hobbes: The Series:

"Calvin's Batman Adventure" (appearance)

"An MTM Episode" (voiced)

Voiced by: Norman Lovett

Arguably the most useful of Calvin's inventions, being a Do-Anything Robot. Though he doesn't have much of a personality in Seasons 1 and 2, when he gains speech in "An MTM Episode", he finally becomes something of a proper character.

• A Day in the Limelight: "An MTM Episode"
• Deadpan Snarker
• Defictionalization: Inverted: this CD player was the inspiration behind his appearance.
• Do-Anything Robot
• Energy Weapon: He can fire them.
• The Faceless: He is often described as looking like an "electronic pancake".
• Four-Temperament Ensemble: The Phlegmatic, along with Hobbes.
• Forgotten Phlebotinum: His time machine function is mostly forgotten about later in the series.
• Fun with Acronyms: He's a Mini Time Machine.
• Kill It with Fire: Emergency Protocol #5557490 is a large burst of fire.
• The Load: During "An MTM Episode".
• Mr. Exposition
• Non-Indicative Name: He started as a smaller time machine, but eventually became a Do-Anything Robot.
• Our Time Machine Is Different
• Shock and Awe: Can fire lightning bolts.
• Sixth Ranger: Technically he was with Calvin since the start, but he became more prominent once he gained speech.
• Spell My Name with a "The"
• Suddenly Voiced: When Calvin installs a voice chip in him.
• Talking Appliance Sidekick: He's a CD player.
• Teleporters and Transporters: Functions as one.

Antagonists

All

• Evil Laugh: Most of them have done this at one point or another.
• Rogues Gallery

Franklin J. Brainstorm

Debut: "The Yellowstone Monster Part 1"^note or, canonically, the rewritten version of Calvin and Hobbes: The Movie

Voiced by: Neil Crone

An extremely inept card-carrying Mad Scientist. Though he has invented several objects of note, they almost always malfunction or blow up in some way.

• Always Someone Better: Thunderstorm is this to him.
• Anime Hair
• Anti-Villain: Type I.
• Big Bad Wannabe
• Bungling Inventor
• Card-Carrying Villain
• Catchphrase: See below.
• Do Not Call Me "Paul": "IT'S DOCTOR BRAINSTORM!" However, when Jack finally calls him as Dr. Brainstorm, he feels that it doesn't sound right, so he decides to let him keep calling him Frank.
• Early-Installment Weirdness: His first few appearances had him with unfocused gold eyes. He later gets green eyes.
• Enemy Mine: Tries his hardest to defy this trope in "62 Percent More Evil"; ends up falling into it anyway.
  • The same thing ends up happening in "Thunderstorm".
• Even Evil Has Standards: Gets horrified when he found out that Rupert tortured his own crew.
• Evil Redhead
• Fiery Redhead
• Fish Eyes: In his first few appearances.
• Harmless Villain
• Heel–Face Turn: In the rewrite of Retro Chill, he realizes his goal of world domination will never be achieved and decides to give up on evil.
• Ineffectual Sympathetic Villain: He's actually saved the world more times than he's taken it over.
• Jerk with a Heart of Gold: When he's not trying to take over the world, he's actually a pretty decent guy. He once fell into a panic when his dramatic chase scene ended up injuring Andy.
• Last-Name Basis: He insists upon it. It doesn't work.
• Let's Get Dangerous!: Inept as he may be, he has moments of competence and/or evilness. The heroes almost always get caught off-guard by this.
• Mad Scientist
• Morally Ambiguous Doctorate
• No Indoor Voice
• Sibling Rivalry: With Sheila. Inverted with his relationship with Thunderstorm. They ''are not'' biological siblings but their rivalry in college could be easily mistaken for this.
• Palette Swap: Of Brainstorm..
• Significant Greeneyed Redhead
• Stuff Blowing Up: Very often.
• Worthy Opponent: He sees Calvin as this.

Jack T. Robot

Debut: "The Yellowstone Monster Part 1"^note or, canonically, the rewritten version of Calvin and Hobbes: The Movie

Voiced by: Michael Brandon

A snarky robot. Not really evil, but he did have a Morality Dial (that was thankfully removed).

• Arm Cannon: Gains a Type 2 when evil.
• Cliché Storm: In-Universe; when he turns evil in "62 Percent More Evil", he gets called out by the heroes for not having an original bone in his body.
• Deadpan Snarker
• Evil Counterpart: Can be seen as one to the MTM, as they're both snarky Do Anything Robots.
• Good Thing You Can Heal: Given that he lives with Dr. Brainstorm, this is highly likely.
• The Load: During "Robot's Day Out".
• Losing Your Head: Happens occasionally.
• Morality Dial: He has a Simpsons-esque one that gets flipped by accident in "62 Percent More Evil".
• Not So Stoic: When those rare times eventually come, you just '''know''' something's wrong.
• Pulling Themselves Together: Which is exploited by Calvin in "Robot's Day Out", taking him apart in order to fit him in his backpack.
• Punch-Clock Villain: He regularly chats with the heroes and doesn't care much for Brainstorm's schemes.
• Red Eyes, Take Warning: When his Morality Dial is flipped.
• Shout-Out: His full name recalls that of Crow's.
• Snarky Nonhuman Sidekick
• The Stoic: There are very rare times where we see him not being a snarky, lazy bum.

Rupert Chill

An alien king out to get Calvin.

• Aliens Speaking English
• Bad Boss: Rupert is willing to go so far as to torture his own crew.
• Hoist by His Own Petard: In his earliest appearances, Rupert would disguise himself whenever he'd arrive on Earth as a human criminal of the same name. (The Season 3 episode "The Five Calvins" implies this was intentional on alien!Rupert's part.) This comes back to bite him at the end of the Season 5 premiere when Calvin arranges for Rupert to be arrested by police while wearing his human disguise.
• The Caligula: Rupert is the ruler of the planet Zok, yet seems to spend most of his time attempting to invade the Earth, trying to kill Calvin and his friends, yelling at his crew, or some combination thereof.
• Revenge Before Reason: After his Sanity Slippage in the rewritten Calvinverse, Rupert will stop at nothing to get back at Calvin and his friends, often resorting to needlessly elaborate schemes just to make Calvin's life a living hell. This gradually comes at the expense of his own men, to the point where Earl is actually considering defecting to Calvin's side in the events of Retro Chill.
• Sanity Slippage: Rupert loses a few screws after the Season Five premiere.
• They Just Dont Get It: The only reason they believe that Calvin is the Supreme Earth Potentate is because Galaxoid and Nebular told them. They steadfastly believe this to be true, despite all evidence to the contrary (including Calvin flat out telling them).
• Villainous Breakdown: Rupert has been in one since his defeat in the Season Five premiere. See Revenge Before Reason above.

Earl

Rupert's right hand man and captain of the moronic crew.

• Aliens Speaking English
• Bad Boss: He's just as willing to torture the crew, but he has limits.
• Character Development: His friendship with Rupert continually deteriorates from Lost at Sea onwards, due to the latter's Sanity Slippage, to the point he's genuinely considering a Heel–Face Turn in Retro Chill.
• Hazey Feel Turn: In Retro Chill - his relationship with Rupert has fallen apart, and then Calvin saves his life, causing him to seriously reexamine his life decisions so far.
• Only Sane Man: Thanks to Rupert's Sanity Slippage in the rewritten Calvinverse, by the time Double Trouble comes around, Earl is one of the only major villains^note (if you don't count the Brainstorm robots, anyway) who hasn't been completely consumed by madness, bloodlust, and/or idiocy.
• They Just Dont Get It: For much of the series, he's just as deluded about Calvin being the Earth Potentate, but by Double Trouble, he reveals he's known the truth for some time - he just doesn't care anymore.

Rupert and Earl's Crew

A crew of harmless villains under the former two's command.

• Aliens Speaking English
• Dumbass Has a Point: Near the end of Double Trouble, the crew is not amused to discover just how much effort it took them so far to conquer just one small town, with a crew member outright questioning how much more it'd take to overthrow the rest of Earth. Earl finds himself agreeing with the crew for once, which goes to show just how unhinged Rupert has become.
• Harmless Villain
• Quirky Miniboss Squad
• Surrounded by Idiots

Retro Griffin

Debut: Can You Imagine That?

A Mad Scientist who kidnapped children sans Calvin and attempted to use their imagination to take over the world, but was defeated and taken to Galixoid and Nebular's planet as punishment.

• Anime Hair: Has it in a "Three Stooges" style that is lamshaped by pretty much anyone.
• Big Bad: Of Can You Imagine That? and Trouble Island.
• Break Them by Talking: Gives Calvin a harsh "The Reason You Suck" Speech in "Trouble Island".
• Cool Car: His claw car, in which he is aware of its coolness.
• Darker and Edgier: Is certainly one of the more serious villans. Especially his remake counterpart.
• Death by Adaptation: Quite possibly considering the cliffhanger in the most recent chapter of the "Can You Imagine That?" remake. Thankfully though, this is inverted.
  • Disney Death
• Evil Laugh: Obviously.
  • Inverted with his remake counterpart.
• Freudian Excuse: The bonus chapter of Retro Chill gave him one however this is yet to be established.
• In-Series Nickname: "Larry" by Calvin and Socrates.
• Mad Scientist
• Odd Couple: Compare him to his sidekick.

Bob

Debut: Trouble Island

Human Retro's harmless sidekick. Mainly the Chew Toy.

• Big Bad Wannabe: It's implied in Retro Chill that he wishes to be a good villain like Retro.
• Chuck Cunningham Syndrome: Isn't seen after his second appearance in Retro Chill.
  • He doesn't appear in the rewritten versions of Trouble Island or Retro Chill, either.
• Cowardly Lion: Just as bad as Hobbes.
• The Chew Toy: When he was on Retro and Rupert's side, anyway.
• Deadpan Snarker: More evident when he becomes good, but he has managed to sneak a few snarks about his former boss when he worked for him.
• Hates Being Touched: With the aliens, at least.
• Heel–Face Turn: Sides with Calvin after realizing how much of a nightmare working with Retro can be.
• Shrinking Violet: Can get really worked up sometimes.
• Took a Level in Badass: Somewhat. He isn't afraid of Rupert and the aliens anymore but he is still easily frightened by Evil Calvin coming towards him in a strangling position.
• We Need a Distraction: A rather pitiful one.

Rupert Chill (The Human)

Debut: ''Calvin and Hobbes: The Movie

An insane convict who is the twin brother of John Chill.

• Adaptational Angst Upgrade: His character is almost entirely revamped and deconstructed in the rewritten version of Double Trouble to be a tragic Shell-Shocked Veteran who only kidnapped Calvin due to being manipulated by Alien!Rupert, which certainly didn't do any favors to his already broken mind.
• Big Bad: Of Which Way Is Where?
• Cool Car: Usually stolen, of course.
• Evil Is Hammy: Ho boy...though it's entirely averted in the rewrites.
• Genius Ditz: Like Dr Brainstorm, he is one of those "stupid geniuses", at least in the original stories.
• Hidden Depths: Apparently, he can outrun the police and is very good at capturing people.
• Revenge: His main reason for targeting the titular duo in Which Way Is Where?
• Pity the Kidnapper: Is put through a living hell thanks to Calvin in Double Trouble. The rewritten version of Double Trouble takes a far more tragic spin on this trope, however.
• Villain Ball: Many of his actions in the original stories are questionable like when he searched for our heroes in a classroom by flipping over 25 desks instead of looking under and even ate the gum off the bottom of one.

Other

Calvin's Parents

Debut: "Birth of a Friendship"

Calvin's mom is voiced by: Jennifer Love Hewitt

Calvin's dad is voiced by: Bill Murray

Calvin's parents.

• Bourgeois Bohemian: Calvin's dad, big time. He gets a big kick out of suffering.
• Deadpan Snarker
• Drowning My Sorrows: In "New Year, New Disasters":
  Dad: Come on, dear. You can drown your sorrows in the cider.
• Misery Builds Character: Dad thinks hanging on a cliff on the edge of the Grand Canyon builds character.

Susie Derkins

Voiced by: Dakota Fannings

Calvin's neighbor. She is his age and goes to school with him. She is constantly being annoyed by him.

• Aw, Look! They Really Do Love Each Other: When Calvin nearly drives himself insane trying to be good so that Karma won't hurt him, it's Susie who talks him down.
  Susie: Calvin, you live by your own rules! You make things up! You create! You destroy! You tease temptation! You do all sorts of horrible things, most of them to me, yes, but then there are days you do good all on your own! You shouldn't let something like Karma run your life! You need to be rude and nasty and gross and weird, so that you can be good on your own accord.
• Belligerent Sexual Tension: While it is still downplayed like it was in the comic strip, Calvin and Susie have had the odd quasi-romantic moment.
• Berserk Button: While she's harmless enough at face value, all it takes is Calvin throwing a water balloon or a snowball at her to unleash the wrath of hell upon him.
• Repeat What You Just Said: Sometimes Hobbes will go off on a hypothetical romantic tangent about Calvin's supposed secret feelings for Susie. While the comic strip's Calvin would've usually started fighting him, this version of Calvin prefers the more subtle approach: "I'm sorry. What did you say?" in a dangerously low voice. Hobbes tends to shut up after that.
• Tsundere: Type B.

Moe

Voiced by: Elizabeth Daily

The bully who is constantly harassing Calvin.

• The Chew Toy: If someone's gonna suffer thanks to the events of the episode, chances are it'll be Moe. Among other things, he's been beaten up by Calvin using the Time Pauser, attacked by a monkey, had a ghost transferred into his house, been forced to apologize to Calvin by Ms. Wormwood, been captured by Dr. Thunderstorm, been tormented by Socrates in Calvin's body, entered a funhouse haunted by a poltergeist, been deafened by the Scream Horn, and that's not even getting into what happens in Retro Chill. Of course, he deserves every bit of it.
• Dirty Coward: Especially egregious during the rewritten Retro Chill.
• Dumb Muscle
• Gang of Bullies: Moe has a gang sometimes.
• Jerkass: Constantly and purely.
• Sorting Algorithm of Evil: Moe gets hit with this hard, especially in the rewritten Calvinverse. By the time of the events of Retro Chill he is so far down Calvin's list of enemies that the latter isn't even slightly afraid of him anymore.
• Stealth Insult: Calvin usually manages to whip these out at Moe.

Miss Wormwood

Calvin's teacher. She's constantly disciplining him.

• The Alcoholic: Calvin says to Mr Spittle she still drinks Maalox right from the bottle.
• Stern Teacher: She really seems to dislike imagination. Then again, Calvin's imagining stuff during class...

Rosalyn

Calvin's babysitter still appears from time to time.

• Badly Battered Babysitter: In her first appearance, Rosalyn finds herself involuntarily riding with Calvin and Hobbes in their wagon all across town!
• Character Development: Of a sort. In the rewritten version of Retro Chill, her arc essentially picks up where the original strip left off, with her and Calvin finding common ground in the latter's enjoyment of games. Here, she even struck up a deal with him, purposefully playing up his reputation to get extra money from his parents and then splitting the earnings with him.

Galaxoid and Nebular

Some aliens who appeared towards the end of the original strip. They keep in contact with Calvin and Hobbes during the series.

• Aliens Speaking English
• Innocent Aliens: Unlike Rupert and Earl, these two are friendly and come from a peaceful planet.

The Klein Family

A family of Inexplicably Identical Individuals (named after their voice actor). They're the only adults Calvin considers "cool". They play a major role in The Collective, where it's revealed that they're Human Aliens who came to guard the Earth, and have been reduced in number.

• Benevolent Alien Invasion: The reason they're here.
• Competence Zone: As mentioned above, they're an aversion.
• Inexplicably Identical Individuals: That's because they're aliens.
• Healing Factor: When Hobbes accidentally scratches one of them, the wounds heal quickly.
• Human Aliens: As revealed in The Collective.
• Motor Mouth: The Klein at the prank store listing the items the Prank Starter Kit contains in "Let Us Prank the Fool":
  "Well, we have your standards. We got your whoopee cushions, we got your squirting flowers, we got your spinning bowties, we got regular ties that roll up like noise-makers, we got your trick wires, we got pies, we got joy buzzers, we got silly string, we got condiments, we got fake gum, water balloons, disguises and mustaches and roller skates and fake hands and fake thumbs and fake toes and a fake nose and wigs and exploding figs and bending twigs and fake wings and ding-a-lings and loads and tons of other things! We got yo-yo's with invisible strings! We got sunglasses with songs to sing! We got dental floss and balls to toss, action Diana Ross! We got magnets and fragments and flip flops and garden crops! We got worms in a bag! We got a suit with a tag! We have also a TV that doesn't change channels! Air conditioners stocked from air from our air conditioned air condition factory!"
  (he then wipes sweat from his brow and gasps for air)
• Tough Room: Averted with the Klein at the carnival; his jokes are apparently uproarious.

The Entity (Unmarked Spoilers!)

A mysterious...well, entity who has overseen many a scenario in the "Calvinverse", supposedly feeding off of the energy such events give off. It finally shows itself proper in the rewritten version of Retro Chill.

• Eldritch Abomination: Whatever the Entity is, it is beyond worldly (let alone human) comprehension. Not really on the same plane of existence as everyone else? Check. Suggested to have had a hand in previous Calvinverse events? Check. Makes its presence known with blinding light? Check. What little we see of it being long, dark tentacles? Check. Not having any specific preference for good or evil? Check. Implied to be at least somewhat responsible for Hobbes being "real?" Aaaaand check.
