The star of the show and the current Norrisville Ninja. Armed with his magical ninja suit, Randy will take on monsters and madmen as he attempts to keep that creepy Sorcerer in his hole.
- Adorkable: More specifically, he's one of those characters who thinks he's cool and tries to act cool, but is actually an enormous dork.
- Ascended Fanboy: Was the Ninja's biggest fan, and now he is the Ninja.
- Badass: As the Ninja, he beats up all the monstrous minions of McFist and the Sorcerer.
- Badass Adorable
- Badass Normal: Without the suit, he's still willing to do things like dive off the side of a dam and tackle a panther to try and save a friend.
- Bee Bee Gun: In the form of the Ninja Bee Ball. The bees however, attack everyone, including him.
- Book Dumb: He’s failing science, and doing poorly in most (if not all) of his classes, but he’s shown to be awesome at riddles. The first episode shows that he's pretty good at (BSing) English too since he got his highest grade so far—a B.
- Byronic Hero: Downplayed. He's a pretty decent person prone to mistakes, but is learning.
- Calling Your Attacks: He loves taking this Up to Eleven.
- Catch Phrase: "What the juice?!" He also has a number of Catch Phrases in the form of odd euphemisms and lingo, such as "that's the cheese" (that's the best), "so honkin' bruce" (that's freaking awesome), "shnasty" (extremely gross), and "so wonk" (so lame), many of which are Share Phrases.
- Character Development: While a pretty okay guy, he is learning several lessons about heroism and duty making him a better person.
- Chick Magnet: He woos Theresa Fowler and Debbie Kang in Night of the Living McFizzles.
- He also flirts with several other girls in Viva El Nomicon.
- Theresa definitely has a crush on him, as "Randy" flirting with Heidi right in front of her in Shloomp, There It Is! is enough to stank her, and it's resolved when he gives her some flowers and apologizes.
- Clothes Make the Superman: The Ninja suit. However, as Howard's disastrous time as the Ninja proved, it's Randy's courage and compassion that make him capable of true heroism.
- Cloudcuckoolander: Randy is definitely more than a bit odd and spastic, though he is often Closer to Earth than Howard.
- Cool Loser
- Distressed Dude: He is sometimes this in recent episodes, starting with Nukid on the Block. Although he's usually more of a badass-in-distress and less of a dude-in-distress than Howard, there are a fair few exceptions; Nukid on the Block where Howard stops Franz Nukid from choking him to death, Bash Johnson: 11th Grade Ninja where Bash (the actual dude-in-distress) kicks away the Robo-Ape trying to vaporise him, Sorcerer In Love 2: The Sorceress' Revenge where Howard has to save him from being dragged into another dimension, Shloomp, There It Is! where Howard has to break the chair he's tied to before he can escape, Julian's Birthday Surprise where Howard basically barters for him (seeing a pattern here?), and Fudge Factory where he's only saved by the timely arrival of Marci and her mother.
- Badass in Distress: Proves to be this in Der Monster Klub, Raiders of the Lost Nomicon, Secret Stache, Swampy Seconds, McFear Factor and Ninjception. In all of these episodes, he escapes on his own.
- Dual Wielding: Often does this with his weapons.
- Elemental Powers:
- Blow You Away: The Air Fist.
- Playing with Fire: Ninja Rage lets him launch fireballs. As well as those Ninja Hot Balls.
- Shock and Awe: Electroballs
- Kill It with Ice: Ninja Cold Balls, and in one of the games he has a Ninja Cold Rage.
- Dishing Out Dirt: The Earth Attack. Which doubles as a Mook Maker.
- Making a Splash: The Hydro Hand which lets him materialize water out of his hands.
- Enemy Mine: With Viceroy against Jerry Driscoll in Dawn of the Driscoll.
- Expy: He slightly resembles a young Stanley Ipkiss.
- Friend or Idol Decision: In "Evil Spirit Week", though he barely hesitates once presented with the decision.
- Hammerspace: Where he pulls his ninja gear from, since the suit has no visible storage space.
- Healing Hands: The ninja art of healing. The first time he tried it he did not fully read how to do it and accidentally brought Jerry Driscoll's skeleton back to life (as well as multiple miscellaneous creatures in the science classroom). He has more control of it by the time of Silent Punch, Deadly Punch.
- Henshin Hero: Randy becomes The Ninja by putting on the mask of the suit, complete with Transformation Sequence.
- Heroes Want Redheads: Reveals at the start of the second season that he finds Heidi to be rather attractive given the right lighting.
- Heterosexual Life-Partners: With Howard.
- He Cleans Up Nicely: He looks good in a tuxedo.◊
- He's Got Legs: He's essentially very little torso and all legs. Certain angles seem to focus on his legs.
- Highly Visible Ninja: Not much into stealth but can be if he has to.
- "How Did You Know?" "I Didn't.": Back when Randy and Howard were six-year-olds, they snuck into Norrisville High so Randy could prove to Howard that the Ninja exists. Randy turned Marci back to normal by cutting her apron. When the Ninja of 2005 asked him how he knew it'd de-stank her, Randy said he was aiming for her head. The Ninja of 2005 then hoped Randy would never become the Ninja.
- Idiot Hero: Originally this, but as he became more studious and savvy, his misunderstandings with the Nomicon primarily occur due to his selfishness and stubbornness instead of pure idiocy.
- Improvised Weapon User: Often uses nearby objects when not using the weapons in the suit.
- In the Hood: He often wears a jacket that has a hood but rarely uses it.
- James Bondage: Is this in Der Monster Klub and Secret Stache.
- Jerk with a Heart of Gold: Downplayed. He wasn't really a Jerkass to begin with, though he has his moments of being a jerk which are often rare for him to do so. On top of that, Randy is just a nice guy to begin with and he's much less of a Jerkass than Howard who's really a jerkass with a heart of gold.
- Kamehame Hadoken: The Ninja Air Fist.
- Kid Hero: He's a teenager and also the only one keeping the Sorcerer from taking over the world.
- Legacy Character: Before he became the Ninja, many others assumed the identity to fight the Sorcerer.
- Living Legend: The Ninja has protected Norrisville for years, making Randy fit the trope by being the new Ninja.
- Mad Mathematician/Good with Numbers: His math skills were mentioned on his essay in Last Stall on the Left and then shown in Escape from Detention Island while proving Howard's innocence to Principal Slimovitz.
- On the other hand, Randy likes to cover up the Nomicon with his math textbook.
- Magic Knight: Is slowly coming into the mystical powers of the Ninja.
- Mask of Power: The Ninja Mask, when worn it becomes the Ninja Suit unless you lose the power for abusing it.
- Messy Hair
- Nice Guy
- Nice Job Breaking It, Hero: Constantly, a lot of the situations are usually caused by him either from misunderstandings, slip of the tongue, bouts of selfishness, misuse of power, acting too rashly or just general neglect on his part. Though most of the time he does mean well and can be counted on to fix his mistakes once it's pointed out to him.
- Ninja: The current Norrisville Ninja.
- Ordinary High-School Student
- Power Incontinence: It happens to him in "Best Buds" after the Ninjanomicon improves his taste buds.
- Plot Allergy: The beginning of "Secret Stache." Turns out he's allergic to Mr. Weinerman's cologne which resulted in him not being able to join the Secret Stache Society
- Pragmatic Hero: Has shades of this at times; in "Flume-igation" he considers just letting the Shark-Derminator kill Viceroy and McFist so he "can be done with them forever", and the main reason he doesn't is because he knows the Nomicon will chew him out for it later if he does.
- Protagonist-Centered Morality: Subverted. He has a tendency to consciously twist whatever lesson the Nomicon is trying to teach him into support for what he wants to instead of what he needs to do. Partially justified as Nomi!Randy all but implies that he was formerly a self-centered slacker on Howard's level before becoming the Ninja.
- Scarf of Asskicking: It's also a pretty handy ninja tool.
- Ship Tease: A lot with Theresa Fowler, several times throughout the first season; less so in Season 2, but it is still there. To a lesser extent with Heidi Weinerman and as the Ninja he has some with Debbie Kang.
- Shirtless Scene: He has one in Ninja Camp.
- Stock Ninja Weaponry: Has used some as the Ninja.
- Super Senses: At their strongest, they become so potent that he can taste things with his skin. On this level, they become Awesome, but Impractical due to the Sensory Overload and how his attacks end up hurting himself more than his enemies because of his increased sensitivity to pain. He does however, manage to reign them in to a more manageable degree.
- Took a Level in Badass: Implied subtly but it's there. Compare how he fights in the first episode to his prowess in Monster Drill.
- Wake Up, Go to School, Save the World: More like save the school too.note
- Why Did It Have to Be Snakes?: His phobia as revealed in McFear Factor are chickens and a rooster.
- You Gotta Have Blue Hair: Turns out he's naturally purple-haired as revealed in "Secret Stache". And he even dyes part of it blue in "Unstank My Hart".

Howard is Randy's best friend, and despite the fact that he’s got a huge mouth, he is the only person who knows Randy is the Ninja. He is Heidi's younger brother.
- Acrofatic: It turns out he can climb the rope for gym class. He just doesn't want to do it.
- He can also beat an un-powered Randy and Bash in a rush to Shangri Lunch in Der Monster Klub.
- However, when Randy briefly took control of his body, he found that he was unable to properly use his usual acrobatic fighting style, prompting him to fight more defensively.
- Action Survivor
- Annoying Younger Sibling: To his sister Heidi.
- Big Eater: He really likes to eat.
- Big Fun: In a Jerk with a Heart of Gold sense.
- Book Dumb: He fails even Spanish class.
- Brilliant, but Lazy: Most likely, see his Chess playing skills in Stanks Like Teen Spirit
- Demonic Possession: Twice. The first time when Randy accidentally freed the Tengu. The second time when Randy freed the Tengu deliberately to better fight the Sorcerer.
- Distressed Dude: More so than Randy, both in older episodes and the more recent ones. Sometimes he escapes all on his own without Randy's help and sometimes Randy has to rescue him before things could get any uglier.
- Dumb and Drummer: He may be dumb in school, but he can really play.
- Eskimos Aren't Real: He doesn't believe isosceles triangles are real.
- Fake Ultimate Hero: During his brief stint as the Ninja, his boorish behavior and abuse of his position for personal gain even made the amnesiac Randy, who was initially elated that his best friend was the Ninja, realize that he wasn't the real deal.
- Fat Best Friend: Combo of C and A, but his build isn't often pointed out; in fact, the one time it looked like they would (when he finds out that Randy didn't think he could climb the rope in gym class), it turns out Randy actually had his "dainty" hands in mind.
- Friend Versus Lover: He gets annoyed when Randy and Theresa interact with each other and tries to include himself in their interaction as shown in Sorcerer in Love 2: The Sorceress' Revenge and The Brawn Also Rises.
- Genius Ditz: Turns out he's super good at Chess.
- Heterosexual Life-Partners/Vitriolic Best Buds: With Randy.
- Idiot Savant: Great at making excuses and playing chess (despite not knowing what the pieces are even called) though not much else.
- It's All About Me: With Randy being a close second.
- Jerk with a Heart of Gold: More so than Randy in the Jerkass department. He can be a jerk sometimes, but he really does have Randy’s best interests in being someone in high school at heart.
- Jerkass Has a Point: Brimming with bad advice, but has occasional moments of practicality and wisdom.
- The Lancer: Defaults to this position as the only other person who knows Randy is the ninja, though he has manned the suit before and done a little saving of his own (not really at the same time, though).
- Last Name Basis: Very rarely ever calls Randy by his first name.
- My Sister Is Off-Limits!: In Shloomp! There It Is!, despite not being fond of his sister, he was horrified and disgusted when "Randy"note flirts with Heidi.
- And in "Welcome Back Catfish", when Howard gets offended that Randy doesn't tell him everything, Randy (possibly jokingly) admits that he finds Heidi attractive under the right light, which Howard finds disgusting.
- Nominal Hero: Incredibly selfish and rude, he only ever does the right or noble thing out of necessity. That said he does care for Randy and when seeing him in real danger, he'll usually act without a second thought.
- Plucky Comic Relief: He mainly exists to provide laughs.
- Secret Keeper: Although he almost slipped in Gossip Boy.
- Ship Tease: He has always acted like he hates Debbie Kang, but when he makes up a story she is all over him.
- Skewed Priorities: Shows this some times. As seen in Viva El Nomicon.
- Too Dumb to Live: Tends to ignore Randy's warnings about McFist's products. Such as their candy which turns people to zombies, and their soupsickles which turns people into soup crazed monsters when he eats a dozen of them.
- Walking Techbane: In Weinerman Tested, Cunningham Approved he shows an astonishing knack for finding the one flaw in "indestructible" McFist products. Some of them disintegrate with one touch.
- What the Hell, Hero?: While understood, one would think Howard would show his friend some slack when he has to go off and fight monsters."Nonono priorities. First our grade, then snakey-flying-thingie."
A magic book containing all the knowledge and wisdom of all the former Ninjas that have written in it. Though it does not speak, it acts as an unorthodox mentor to Randy, oftentimes giving him advice or disciplining him when he goes too far. The protagonists often talk to it as if it's a character in and of itself.
- An Aesop: Tries to give one to Randy every other episode to mixed success as the boy often misinterprets or twists the lesson to fit what he wants to do at the moment.
- Art Shift: Its interior has a visual style that is quite distinct from the rest of the show.
- Augmented Reality: Gives Randy a mystical version of this that uses colorful doodles to highlight points of interest, help him deduce solutions to a problem, or to stress the lesson it was trying to teach him.
- Notice This: A non-videogame example. Randy's bond with the Ninjanomicon often results in him seeing arrows point at stuff that he can use to his advantage.
- Bigger Stick: Its solution to dealing with a mighty force is to use an even bigger one to counter it. This doesn't necessarily mean an attack or weapon; a drop off a cliff or something really heavy falling on the opposition is perfectly acceptable.
- Brain Uploading: How it brings people into it. It's possible for the wrong consciousness to enter a body on way out though.
- Chekhov's Classroom: Usually predicts the plot of the entire episode and lays out the Aesop preemptively in the form of a surprise lesson.
- Dangerous Forbidden Technique: Has a few in its "Forbidden Knowledge of the Shadow Warrior" section that include telepathy, flight, invisibility, and healing. Their true danger lies in how they require a good deal of study and practice to use safely.
- Forbidden Chekhov's Gun: Randy tried to use some techniques to add some terror to his garage on Halloween.
- The Kindnapper: Pulls this on Randy in ''Shloomp, There It Is!", tying him to a chair inside itself and sending out NomiRandy to try and force Randy to learn that he can't rely on it for absolutely everything.
- Laser-Guided Amnesia: What it does to a Ninja after their tenure has ended. The memories and experiences aren't exactly erased, but are instead taken into the book to help future Ninjas.
- Licked by the Dog: Despite Randy's many screw-ups, the Nomicon still considers him to be pure of heart and exceptionally courageous.
- Made of Iron: The Ninjanomicon can't be destroyed.
- Made of Indestructium: For a dusty old book that has to be handed down through an 800-year-old (and technically endless) time loop, it's miraculously durable.
- Meaningful Echo: Every single time, Randy has to repeat the lesson out loud to understand it.
- Mind Hive: The Nomicon has the collective wisdom of every Norrisville Ninja ever, it’s clearly sentient.
- My Own Grandpa: The Ninjanomicon exists because Randy gave his blank volume to the First Ninja in order to fix the time stream.
- Only the Chosen May Wield: It can make itself virtually inaccessible to anyone, including Randy. The only one powerful enough to force it open regardless is the Sorcerer.
- Scenery Porn: Chock full of it.
- Snarky Inanimate Object: For a book of nijaa wisdom, it often jokes around with Randy.
- Stable Time Loop: Part of its origin.
- Tome of Eldritch Lore: Like the Necronomicon it's based off of, the book itself is not actively malevolent, but the knowledge inside of it is dangerous if misused.
- Trickster Mentor: Though it's often blunt, it can go to exotic lengths to teach Randy a lesson.
- Unknown Rival: Advised Randy against letting Howard be a part of his life as the Ninja, but has since dropped this stance and has even supported Howard's side on certain subjects. In contrast, Howard has only gotten more resentful of the tome over time, considering it a rival for Randy's attention and respect.
- Your Mind Makes It Real: Once inside, a person can freely manipulate the world within its pages.

The owner of McFist Industries. He made a deal with the Sorcerer to destroy the Ninja for a superpower.
- Artificial Limbs: Has a mechanical right arm that has a brain and a pair of eyes.
- Badass Mustache: So much so, he founded the Norrisville High Mustache Society.
- Bald of Evil: He has no hair on top of his head.
- Blond Guys Are Evil: He has blond hair.
- Broken Pedestal: For Randy, upon discovering that he's both evil and behind all the robot attacks on the school.
- The Chessmaster: Surprisingly becomes this in McCluckerbusters managing to manipulate events to almost put two of his competitors out of business, so he could corner the market on fast food.
- Corrupt Corporate Executive: Highlighted in Happy Hanukkah Howard Weinerman where he almost turns Greg's Game Hole into a shoe store since there weren't any functioning video games despite the fact that it was one of HIS robots that destroyed all the video games in the first place.
- Deal with the Devil: With the Sorcerer, to get a superpower all he has to do is break the Sorcerer out by destroying the Ninja.
- Devil in Plain Sight: He's this to the general public, who in turn adore him a lot for being the head of the city's major consumer products company. It's incredible how everybody ignores the right cyborg arm with a brain with eyes on the wrist. That is SO TOTALLY not evil-looking, oh no!
- This turn out to be a good thing, cause when he lost it, The Sorcerer stanked him and turned him into what could be described as the love child of Blanka and The Hulk, with the brain in his cyborg arm becoming a second head that shoots acid!!
- The Dragon: He mainly runs his operations to serve the Sorcerer.
- Dragon-in-Chief: Although sub-servile to and much weaker than The Sorcerer, as the Sorcerer is presently imprisoned and has to rely on the situation being right for him to case any chaos himself. McFist is presently the more common threat and in the position to cause more destruction.
- Even Evil Has Loved Ones: He loves his wife Marci, to the point where he's horrified when he realizes he's left her behind in Night of the Living McFizzles.
- Fat Bastard: He's overweight and runs a company that hides rather sketchy operations.
- Fiction 500: He nearly owns everything in Norrisville. He even buys Whoopee World and bans Viceroy from it just to punish him for failing."I'm Hannibal McFist, lovable gazillionare! I own this town!"
- Genre Savvy: McFist reveals he is this in "Silent Punch, Deadly Punch" when Randy sneaks into his house.
- He sometimes kidnap teenagers who are mistaken to be the ninja in the more recent episodes, starting with Bash Johnson: 11th Grade Ninja, even though he did kidnap Howard in Gossip Boy upon learning that Howard knows who the ninja is.
- Glad I Thought of It: Constantly tries to take credit for Viceroy's ideas and efforts.
- Hair-Trigger Temper: It is rare for him to go an episode without getting seriously ticked off.
- Happily Married: Oddly enough, he and his wife are clearly on good terms.
- The Heavy: He has a robotic fist of iron and sometimes battles Randy in mechs.
- Idiot Savant: Questionably intelligent in anything not business related.
- Involuntary Charity Donation: McFist becomes a victim of this in "McOne Armed and Dangerous" when the Ninja announces that he's donating one brand-new McFistPad to each person in Norrisville.
- Let's Get Dangerous: When stanked by the Sorcerer, he becomes a scary combination of Acrofatic, Unstoppable Rage and Madeof Iron
- Mega Corp.: He inherited McFist Industries from his father and brother. Hannibal is implied to have made the company even more successful with the help of Viceroy's genius, laying claim to most of Norrisville's public services and businesses. Ironically, because of this nigh-monopoly, its McFist's own property that bears the brunt of the damage during his attempts to destroy the Ninja.
- No Indoor Voice: He yells A LOT.
- Noodle Incident: Why he has a cyborg arm with a brain in it hasn't been revealed, or whose brain that is.
- Out of Focus: In Season 2, with the appearance of Evil Julian and the Sorcerer becoming more proactive, McFist and Viceroy become a lot less relevant to the plot. They still try to destroy the Ninja, but they are not as important anymore.
- Sarcasm-Blind: When McFist and Viceroy were discussing options about which superpower to pick (the Sorcerer will give McFist a superpower if he destroys the Ninja), Viceroy suggested the ability to understand sarcasm. McFist asked when he'd need it.
- Sketchy Successor: In comparison to Terry, the actual inheritor of McFist Industries, he's a far better businessman. The sketchy part comes in due to his moral compass being much more askew than either his dad or brother by virtue of him selling out the planet to the Sorcerer in exchange for superpowers.
- Sucksessor: In one episode, Hannibal McFist creates an alter ego named Lucius O'Thunderpunch to become the town's new hero and make the Ninja feel unwanted. After the Ninja leaves, O'Thunderpunch shows his true colors and the school becomes vulnerable to the Sorcerer until the Ninja returns.
- Sure, Let's Go with That: Hannibal McFist once tried to destroy the Ninja with an Powered Armor. When the Ninja removed the helmet, he assumed McFist was being forced. McFist tried to play along but the Ninja wondered why somebody would force him. Since McFist failed to come up with an excuse, the Ninja figured out McFist is a Villain with Good Publicity.
- In the Season 1 finale, the Sorcerer erroneously believes that McFist made good on his word to free him and neither he or Viceroy feels too inclined to correct him.
- Ugly Guy, Hot Wife: He's not much to look at, while his wife Marci is very attractive.
- Villain with Good Publicity: Lampshaded.Randy: "What better mask for an enemy than that of the most beloved man in town?"
- This is actually a good thing for Randy. When McFist evil becomes public, he focuses all efforts on destroying the Ninja and becomes Stanked, making him an even more dangerous threat.
- Why Did It Have to Be Snakes?: His phobia as revealed in McFear Factor are clowns.
- You Get What You Pay For: In "McSatchle", Viceroy builds a robot with an armor made of McSatchles because they're indestructible. However, McFist had decided to cut costs by making lower quality zippers and it allowed the Ninja to defeat the robot.

An ancient evil defeated and sealed by the Norisu Nine 800 years ago. In the present he made a deal with McFist to give him a superpower if he destroyed the Ninja. He "stanks" students (that is, turns them into monsters to do his evil will) to create enough chaos for him to escape his imprisonment.
- Animal Motifs: Dragons and Tigers. Jhonen pointedly made him lizard-like in appearance.
- Badass: Ultimate evil aside, its impossible to argue the Sorcerer doesn't qualify, being the most powerful and dangerous of all the Ninja's opponents. And even without his magic, as shown in "Randy Cunningham: 13th Century Ninja" he can match Randy in a fight.
- Big Bad: The main antagonist of the series, and the undisputed most dangerous opponent.
- Body Snatcher: "Julian's Birthday Surprise" reveals that the body of the Sorcerer is not his own, but a merchant from the 13th Century that found one of the Chaos Orbs in a lake. The Sorcerer took over the Merchant's body, while the "Merchant" is trapped in the orbs original resting place.
- The Corrupter: He turns people in despair into monsters to do his will.
- When freed, he can do this endlessly by just hitting people or objects with his Stank. As an arguable trade-off, just hitting these monsters hard enough will return them to normal.
- Creepy Long Fingers: His fingers are long and bony.
- The Dreaded: Despite being imprisoned, everyone who knows that he exists is genuinely terrified of him, for very good reasons.
- Enemy Mine: In the season 2 finale, Randy purposefully frees him so he'll be able to combat Mirror Julian and reclaim his power. Course naturally once they beat him, he quickly turns on Randy.
- Even Evil Has Loved Ones: If nothing else, he seems to be genuinely fond of the Sorceress.
- Evil Brit: He certainly has the accent.
- Evil Is Petty: Used his powers in an attempt to destroy the Golden Doctor's Note on a whim. Subverted because there's an implication that it might have made those questing for it vulnerable to stanking.
- Evil Sorcerer: He's an 800 year old version of this.
- Faux Affably Evil: Most of his conversations he comes across as snarky or hammy and his interactions with his rat are cute. However the moment he's free, he transforms nearly the entire city into monsters and lays waste to the rest of Norrisville, all within the span of a few hours. Remember, he killed eight of the Norisu Nine.
- Four Is Death: Before he was trapped by the Ninja, four of his prayer beads were lost in the scuffle and flew off to parts unknown.
- Fusion Dance: His threat is finally ended when the merchant he traded places with is freed from the Land of Shadows and they merge together before the man disappears, but not before thanking Randy for freeing him.
- Hard Light: Can create constructs with his magic.
- In the Hood: He wears a hood.
- Ironic Hell: 800 years ago, he coveted the power of the Tengu Stone. The First Ninja eventually used it to imprison him and he now spends his days chained to a rock with the stone high above him, in his sight, but completely out of his reach.
- Lean and Mean: He is really skinny and the main antagonist.
- Not So Harmless: By the time the series starts, he's actually stronger than he was before he was imprisoned.
- Prophet Eyes: He's a sorcerer with blank white eyes, which help add to his creepiness.
- Sealed Evil in a Can: The last of the Norisu Nine sealed him beneath the Earth, but in the present day, Norrisville High School was built on top of it. He still stirs up trouble in order to free himself.
- Sadist: While chaos makes him more powerful, its undoubtable, a large part of him enjoys hurting people. The sheer look of glee on his face, when he tries to crush the Ninja or when he's destroying present day Norisvile is proof enough.
- Sickly Green Glow: His magic glows green.
- Soft-Spoken Sadist: Though he will raise his voice when he gets angry, normally the Sorcerer talks in a calm tone with his refined voice, even when he's attempting to transform people into monsters or commit murder.
- Sorcerous Overlord: His intention is to become this, and he certainly has the power to pull it off.
- You Have Failed Me: Threatens to call off the deal with McFist if he continues to fail.

McFist's mad scientist who creates whatever evil machinations he asks for.
- Affably Evil: Depending on the episode. He can be genuinely friendly and kind and acts more as a Punch Clock Villain. But he has his moments of being Faux Affably Evil.
- Berserk Button: Do not seperate him from his robot helper Otto.
- Black and Nerdy: He's African-American and a scientist.
- Camp Straight: He often acts effeminate and stylish, but he attempts to hit on Mrs. Driscoll in "Dawn of the Driscoll" and he is shown with a girlfriend named Ruth in "Fudge Factory".
- Crazy-Prepared: Brings a killer robot wherever he goes.
- Deadpan Snarker: He tends to make remarks about McFist never thinking his decisions through and expecting him to have a solution for everything.
- Enemy Mine: With the Ninja against Jerry Driscoll in Dawn of the Driscoll.
- Even Evil Has Loved Ones: In Monster Dump, an amoeba blob becomes his pet. He names it Nicholas.
- Evil Genius: He invents robots to fight the Ninja.
- Faux Affably Evil : Depending on the episode. He's usually Affably Evil, but the Halloween special emphasizes how underhanded and ruthless he can be sometimes. Not only did he betray Driscoll to the authorities to become valedictorian of his class (and is most definitely not sorry for the act), he also ended up purloining the man's death ray decades later. He was also more than willing to use said death ray to wipe out Norrisville and its inhabitants to prevent the zombie plague from spreading, expressing mild glee at the prospect of doing so.
- Gadgeteer Genius: The robots sent to attack the Ninja are his invention.
- Insufferable Genius: So much so that he's taught some of his robots to act smug.
- Intergenerational Friendship: With Ruth Johnson, Hannibal's mother-in-law.
- Labcoat of Science and Medicine: A lavender one.
- Lean and Mean: He's very thin and one of the bad guys.
- Mad Scientist: Not only does he create machines and monsters to attack the Ninja, but it's also established in "Dawn of the Driscoll" that he attended Mad Scientist University.
- Made of Indestructium: Many of the products and weapons he designs for the company are nigh-indestructible. They only break if a minuscule design flaw he overlooked is ruthlessly exploited or if Hannibal himself made some budget cuts during their construction.
- My God, What Have I Done?: He's pretty horrified once he realized that his Darker and Edgier replacement for Whoopee was utterly at odds with the spirit of the character.
- Out of Focus: In Season 2, see McFist.
- Psychopathic Manchild: An ardent lover of theme parks, sweets, and killer robots.
- Punch Clock Villain

The Robo Apes
Voiced by: John DiMaggioThe backbone of McFist's corporate empire who serve a wide variety of functions that keep the various workings and businesses of McFist Industries running. They serve a far more sinister purpose as frontline enforcers of whatever.
- A.I. Is a Crapshoot: Have a modicum of free will that eventually has them turn against McFist. Ultimately subverted in that all they wanted was an apology and are quick to resume their normal duties once placated.
- Blade Below the Shoulder
- Do-Anything Robot: The only task they can't seem to accomplish is destroying the ninja.
- Dual Wielding
- Elite Mooks: Some bear a head crest that mark them as leaders of a sort.
- Killer Gorilla: Especially during Ape Mode.
- Lightning Bruiser's
- Red Eyes, Take Warning: Ape Mode
- Super-Powered Robot Meter Maids: They're powerful enough to give the Ninja a run for his money on occasion. They're also used as waiters, secretaries, cooks, musicians, engineers, janitors among other servile professions with little aesthetic or internal differences among them.
- Talking To H Imself: Well, more like yelling to himself.
- Unstoppable Rage: Ultimately Subverted.
- Zerg Rush: Their usual tactic when fighting the Ninja. This actually becomes effective when they go berserk and attack everything else, rendering Randy unable to stop all their rampages.
Voiced by: David KoechnerThe Ninja of 1985. The only known Ninja to have actually lost the position due to abusing his power and being a jerk. He froze a Stank'd student to let it be a successor Ninja's problem.
- Acrofatic: The guy is FAST for his size.
- The Chosen Zero: At first, Randy thought that Mac Antfee would actually help him regain his confidence of being the right guy to be the ninja because he was the ninja of '85, but when he meets Mac Antfee in person, Randy realizes that Mac Antfee wasn't the past ninja he thought he was - he learns that Mac Antfee was fired from being the ninja because he was such a violent jerk. After learning that Mac is planning on getting the mask, Randy did not hesitate on kicking his butt in his own camp.
- Drill Sergeant Nasty: Played with. While he is most certainly this in his first appearance, his loss to the ninja and Mind Wipe seem to mellow him out and he makes a career out of being a positive motivational speaker.
- Expy: Of John Kreese from The Karate Kid.
- Evil Redhead: After he got stripped off from the ninja mask.
- Genre Savvy: Has an army of Mooks, and a cage, because he knows full well he can't beat the Ninja in a fair fight.
- Held Back In School: He had been the ninja for 6 years, since high school goes from grades 9-12, he was held back 2 years.
- Heel–Face Turn: See Took a Level in Kindness below.
- Hoist by His Own Petard: When he and Randy fight in the Nomicon, he finally incapacitates Randy and decides that instead of just beating him, he's going to mind-wipe him too, throwing him into The Ultimate Lesson despite his protests before turning to the "Exit", just across the hall. Unfortunately for him, it turns out that Randy switched the names on the rooms and intentionally lured him into trying the mind-wipe, leading to...
- Ironic Echo: Between him and Randy.Mac: There's no shame in losing to the class of '85, because we rule! *hurls Randy into The Ultimate Lesson*LaterRandy: Ain't no shame in losing to the class of in your face! *slams the door to The Ultimate Lesson on Mac*
- Jerkass: He left a stanked student in the freezer for over 20 years so he could go to prom. In fact, he was such a jerk, he was fired from being the ninja, being the only one to do so.
- Making a Splash: One of the Nomicon's ninja powers is the "Hydro Hand", allowing the ninja to materialize water in their hand and throw it as an attack. It takes Randy until Happy Hanukkah, Howard Weinerman to learn this ability.
- Red Shirts: Mac Antfee has an army of these (though they're technically Mooks), they're even called that.
- Roaring Rampage of Revenge: He wants to regain the ninja suit, and he has said that once he does, he plans to kick the butts of everyone in the town, because he got fired for being a Jerkass.
- Shadow Archetype: As previously stated Mac Antfee was the '85 ninja, and although he had some skill and more like Randy, he had none of Randy's good qualities, like how Randy tries to make up for his mistakes and stop monsters at personal cost, in fact, he was essentially fired, and wants revenge.
- Top-Heavy Guy: Unlike most examples, this doesn't stop him from kicking really, really hard.
- Took a Level in Kindness: After Randy tricks him into fulfilling the Ultimate Lesson. AKA, wiping his memory of being the Ninja.
- With Great Power Comes Great Insanity: If his memory wiped personality is any indication, he wasn't so bad before he got addicted to the power of the Ninja.
- Voiced by: Andy Richter

- Attack of the 50-Foot Whatever: His true form, a giant robotic version of himself.
- Berserk Button: Cheating or the implication of cheating.
- BFS: His tie transforms into one.
- Death by Irony: The punishments for those sent to his island reflect the crimes the student perpetrated.
- Hard Light: When suitably enraged, his otherwise intangible holographic avatar becomes this. It's tough enough to shatter pillars of stone.
- Ironic Hell: Detention Island is this if you don't play by the rules.
- Knight Templar: He believes that harshly punishing students for even the most harmless of rule breaking is completely justified.
- Well-Intentioned Extremist: Heavy on the EXTREME aspect
A grotesque and powerful demonic bird entity that is the source of the Ninja Suit's power. It is fundamentally linked with the suit's wellbeing; Whatever damage one incurs, the other receives in turn. This also extends to the person (if any) wearing the suit during said injury. It is tentatively sealed in the stone eye of the atrium floor mosaic.
- Attack Its Weakpoint: Its Demon Feathers. After they were stripped from it and turned into the Ninja Suit, the suit itself became its weakpoint.
- Demonic Possession: A fairly persistent variation. Even after being knocked out of its initial victim it will immediately try to repossess its former vessel.
- Expy: Its spirit form (black with a green-white-red max) greatly resembles Aku from Samurai Jack.
- Feather Flechettes
- Glowing Eyes of Doom: When its possessed victim fully transforms.
- Hellish Pupils
- Morphic Resonance: A fully possessed victim does not actually resemble the tengu's true form but carries over several of his/her traits including hairstyle.
- People Puppets: Ironically enough, the Tengu is the puppet. Randy figures out that because the Tengu is connected to the suit, he can control it by making it mimic his movements.
- Red Eyes, Take Warning: People it possesses gradually have their eyes turned red.
- Sealed Evil In A Rock
- The Voiceless: It does not speak.

- The Big Easy
- The Bus Came Back: Returns in a later episode to tell Hannibal and Viceroy what he believes to be the Ninja's true identity in exchange for the latest McFist Pad. This effectively jumpstarts the plot of "Bring me the Head of Reginald Bagel".
- Deep South
- Egomaniac Hunter: Considers himself to be the best trapper in the world.
- Faux Affably Evil: Although he's often polite and doesn't even kill the animals he captures, Catfish has no problems with feeding intruders to his pets or scoffing at Randy's apparent Heroic Sacrifice.
- Foreshadowing: He found one of the Sorcerer's Orbs in his swamp.
- Glowing Eyes of Doom: His eyes glow a foreboding purple whenever he's in an intense emotional state or is in the process of exerting a lot of power.
- Hollywood Voodoo
- Human Resources: Uses living people as furniture or as food for his animal army.
- Mix-and-Match Critters: The form he takes when he uses his gris-gris is reminiscent of several swamp-dwelling creatures.
- One-Winged Angel
- Ragin' Cajun
- Transformation Trinket: His gris-gris. Given its origins and what it actually does, the term is a bit ironic as such talismans are usually made to DETER evil.
An alternate personality to Randy created by the Nomicon and representative of a "no-Nomicon" Randy, he's a flirtatious, irresponsible, and jerky guy who couldn't care less about the lessons he should be learning as the ninja. Though he was originally created by the Nomicon to teach Randy a lesson (trapping Randy in the book and taking over his body), there are signs that he might be capable of independent action and thought, since he prefers life outside the book and uses potentially lethal force on Randy when they confront each other in the outside world.
- Casanova Wannabe: He flirts with practically everyone he sees on a stroll down the corridor, and passes over Theresa (who is already enamoured with him) to hit on Heidi.
- Confusion Fu: Deals with Bash threatening to harm him by...starting up some tunes and breakdancing at him. It works.
- Evil Twin: Of Randy, though he only technically exists inside the Nomicon unless he can hijack a body.
- In the Hood: Randy doesn't usually use the hood on his jacket, but NomiRandy starts using it the instant he escapes the Nomicon.
- Jerk With A Heart Of Jerk: In contrast to Randy's Jerk with a Heart of Gold, NomiRandy is rude to just about anyone Randy considers a friend, breaks Theresa's heart, and spends all of his screentime with Randy either attacking him, taunting him, or both.
The Halloweenja Suit
A variation/mutation of the Ninja Suit that is unleashed when Randy uses the Nomicon's reservoir of fear-based magic.
- Animal Motifs: Snakes.
- Clingy Costume: Briefly refuses to be removed by Randy, but after he keeps trying, the suit decides that it's better off without him and promptly spits him out so it can wreak havoc on its own.
- The Corrupter: It's more or less a mindless version of the Sorcerer.
- Dangerous Forbidden Technique: It's the product of using one.
- Know When to Fold 'Em: When Randy, Howard, and Rachel completely neutralize its army, it decides to flee to fight another day than risk being purified.
- Scary Teeth: Has a mouth full of them.
- Weaksauce Weakness: Cuteness. Shared with its corrupted minions, so much so that a kind hug can bring them back to normal. The Nomicon can also remove the corruption out of the suit if you can get it close enough.
An evil counterpart of Julian, created from one of the Sorcerer's Orbs of Power.
- Ambition Is Evil: Was created to out Julian's desire for the power the Chaos Pearl could give, and his only goal is regain it and gain its great power. Which of "Mastermind of the Disastermind" He's succeeded. Meaning he's now hunting the other three balls, which as of "Winer Takes Ball" He's also succeeded.
- Badass: Armed with incredible magical powers and enhanced physical abilities, evil Julian proved to be one of the few creatures capable of giving Randy a challenge. Following gaining Viceroy's Robot and the sorcerer's ball he only got stronger. Now he has all four balls power he's strong enough to potentially rival the Sorcerer.
- Big Bad Ensemble: With the Sorcerer in Season 2.
- Big Bad Wannabe: While a genuine threat in his own right, he's ultimately no match for the Sorcerer in a direct fight who quickly reclaims the Chaos Orb from him.
- Create Your Own Villain: Generally considered this, as he was created when Randy brought an Orb to Julian's birthday party and didn't keep enough of an eye on it, and then he escapes when Randy and Howard ditch Julian in an ice maze, when he's clearly terrified about something even if he didn't specify that it was someone following him via mirrors. Some have argued that Julian stealing the orb brought it on himself, though, and that Randy and Howard couldn't protect him from the second part forever anyway.
- Dangerously Genre Savvy: He waits until he has succeeded in getting hold of the Chaos pearl before revealing his existence to the Ninja.
- Evil Albino: Contrary to his original appearance in the Season 2 poster and his first episode(granted that might have just been lighting), where he had green hair and eyes, in Snow-Klahoma! his design changes to white hair, white skin and blue eyes.
- Evil Counterpart: Has all Julian's negative traits taken to truly evil levels.
- Evil Sorcerer: Being made by the Sorcerer's Chaos Pearls, he possesses genuine and quite impressive mystical powers.
- Evil Twin: To Julian.
- From Nobody to Nightmare: Julian was, at most, a secondary character. His Evil Counterpart was one of the major villains for Season 2.
- Fusion Dance: Once the real Julian is freed from the Land of Shadows, he's forced to re-merge with him.
- Light Is Not Good: Decked in all white. And some serious bad news.
- Magitek: Able to combine one of Viceroy's robot remains with the power of the chaos Pearl making him near unstoppable.
- Nice Hat: Same top hat as the real Julian, only white.
- No Name Given: Variation; as Julian never had a last name either and this Julian has no canon extra title, there's technically nothing to differentiate the two by name. There are about five nicknames in use for this version of Julian at the moment (including Mirror Julian, Sorcerer Julian, Evil Julian, and Shadow Julian), but "Ghoulian" seems to be the most popular.
- However he refers to himself as Evil Julian in "Mastermind of Disastermind"
- One-Winged Angel: Able to take the form of a terrifying giant monster, that somewhat resembles a stanked Julian.
- Palette Swap: Discussed and mocked; after he escapes, Randy asks if Julian's hat has always been white. Howard didn't even notice that Julian wore a hat.
- He himself Lampshades this in "Mastermind of Disastermind" asking how no one's noticed he wears white while Julian wears purple.
- Took a Level in Badass: Evil Julian was pretty dangerous to begin with, however after reclaiming the Sorcerer ball and combining it with Viceroy's robot, he became near unstoppable.
- Then in "Winner Takes Ball" he gains the power of the other three balls pushing his abilities to unknown heights.
- Soft-Spoken Sadist: Shares his counterpart's soft and calm voice, making him quite chilling when he tries to destroy others.
- Voluntary Shapeshifting: Randy can't destank him due to this, but he willingly switches himself back to human form later on.

However the moment he thought his son was in danger he breaks into McFists weapon storage, steals one of Viceroy's robots, and personally pilots it to destroy the Ninja. He actually manages to come closer to succeeding than most of McFist and Viceroy's attempts do.
- Ugly Guy, Hot Wife: Inverted, Mort's a pretty decent looking guy, however Mrs Weinerman is pretty hideous.
- Well-Intentioned Extremist: He only stayed on to help McFist destroy the Ninja to better provide for his family.
- Yes-Man: In contrast to his rather strong-willed children, he's rather spineless. However "Mort-al Combat" proves he does have his limits, where his son is concerned.
Marci Johnson McFist
Voiced by: April StewartHannibal's wife and Bash's mom. She knows about her husband's quest to destroy the ninja.
- Affably Evil: Unlike her husband and son, she is genuinely kind and friendly. On the other hand, she openly supports her husband's quest to destroy the ninja.
- Beauty Mark: Underneath her right eye.
- Dark Mistress: Slightly deconstructed as her tolerance and acceptance to Hannibal's villainy also extends to her own son's Jerkass tendencies.

- Impossible Hourglass Figure: She has a thin waist, but her chest and hips are quite large.
- Parent with New Paramour: McFist and Bash do not get along.

Voiced by: Steve ZahnHannibal's older brother. The actual heir to McFist Industries.
- Corrupt Corporate Executive: He fears to become like this like his father and brother.
- New-Age Retro Hippie: He has the mannerisms and even ends several of his sentences with "dude" or "man".
- "Well Done, Son!" Guy: He has issues with his father preferring Hannibal over himself.
- With Great Power Comes Great Insanity: After taking over McFist Industries, when the "wind" (fart) powered rides don't get enough power from the cows he switches over to abducting people to harness their prune smoothie induced "wind".
The First Ninja
Voiced by: Joel McHaleThe first of the Norrisville Ninjas and the last of the Norisu Nine.
- 10-Minute Retirement: Leaves Norrisville to its fate after the Sorcerer obtains the Tengu Stone. Randy and Howard's efforts to stop the villain regardless inspire him to come back and help.
- Arch-Enemy: Until their final battle, he was this to the Sorcerer throughout most of his life. On his part, the Sorcerer greatly dislikes him for both banishing the Sorceress to the Land of Shadows and imprisoning him underground.
- Badass: Battled the Sorcerer for years throughout the globe.
- Big Damn Heroes: Prevents the Sorcerer from killing Randy and Howard and finally gets to toss him into the pit.
- Brought Down to Normal: After his time as the Ninja had ended, he put all of his knowledge and experience gained from his tenure into the Ninjanomicon, expelling them from his mind.
- Ice-Cream Koan: Half of his lines are made up of these in contrast to the genuine riddles and lessons the Ninjanomicon provides.
- Kill It with Fire: Has a stronger variation of the Tengu Fire Ball that takes the form of a roaring dragon. It's powerful enough to disable the Sorcerer for a modest amount of time.
- Last of His Kind: His eight "brothers" were all killed by the Sorcerer.
- Martial Arts Headband: As an added bonus, he can use it as a weapon in a similar manner to how Randy uses his scarf.
- Other Me Annoys Me: Randy earns his ire through a combination of ruining his ambush on the Sorcerer and his inability to shut up. Becomes subverted when Randy re-inspires him.
