Main Characters

Bob

^{Click here to see Bob's appearance post-Season 3.}

Voiced by: Michael Benyaer (Seasons 1, 2 and 4), Ian James Corlett (Seasons 3 and 4), Alfonso Obregón Inclán (Latin American Spanish dub)

The Hero. Bob is a Guardian. The Guardians are the net's equivalent to a police force, based in the Super Computer. Their purpose is to mend and defend: repairing damage caused by tears and fighting viruses. Assisted by his Keytool Glitch, Bob has been assigned as the Guardian of the small system of Mainframe, defending the locals from their two resident viruses: Megabyte and Hexadecimal. In Mainframe, Bob is looked up as some sort of Super Hero, especially by young Enzo, who dreams of becoming a Guardian himself. Bob is more prone to the Indy Ploy in comparison to Dot's The Chessmaster approach. Had a Will They or Won't They? thing going with Dot, until they decided to get married.

---

• All-Loving Hero: Bob is very reluctant to hurt others and even supports not killing Viruses, as he believes they can be healed into Sprites. He is distraught by his fellow Guardians having no regard for their lives when brainwashed by Daemon and exhausts himself trying to get them out of Mainframe non-lethally rather than just shooting them down.
• Better Than New: Both Bob and Glitch come back from their near death experience tougher.
• Big Good: Being a Guardian, he's technically the highest ranking of the good guys, but Phong's the local ruler.
• Big Brother Mentor: For Enzo.
• Blue Is Heroic: Bob's so heroic, his skin is blue.
• Brought Down to Badass: On the occasions he has Glitch taken away from him, he relies on his wits and fighting skills alone to save the day.
• Butt-Monkey: He was a bit of this during the first two seasons as a result of his frequent bad luck, but moved past the role after the show's Cerebus Syndrome and his Web-induced character development. When his doppelganger (actually Megabyte) was introduced, this one briefly resumed the role during his impersonation of Bob as a way of driving home the notion that the old Bob was truly back.
• Cast from Hit Points: Being fused with Glitch gave Bob a lot of cool powers, and he did a lot of good with them. Unfortunately, Glitch was damaged when they fused together, so that Bob started to weaken whenever he used his powers. It got to the point where he risked being deleted by using them too much.
• Character Catchphrase:
  • "I don't think so!"
  • "This is bad. This is very bad."
  • "Not good! This is not good!"
  • "Stay frosty!"
  • And when he's really perturbed, (like when he's stuck in a parody of Pokémon) "THAT IS SICK!"
• Character Development: Many fans noticed that Bob's portrayal after returning in Season 3 was a bit different. He was noticeably less cocky and impulsive than in earlier seasons, and comes off as a bit Older and Wiser. Considering the events of the Season 2 finale and Season 3, this makes perfect sense.
• Characterization Marches On: Prior to Season 4, Bob had never displayed his Thou Shalt Not Kill attitude toward viruses, nor had shown any intentions in reforming them. In fact, he outright attempted to delete Megabyte in Infected. He did save Megabyte and Hex on occasions, but he chalked it up to his programming, rather than any belief that they could be reformed.
• Chick Magnet: Dot, Mouse, and Hex have all expressed romantic interest in him to varying degrees.^note Mouse and Hex are far more aggressive while Dot doesn't openly express affection for him until Season 3. At least one female binome has come on to him too.
• The Chosen Many: The Guardians are an entire organization of chosen heroes.
• The Chosen One: According to Turbo, keytools select their guardians, and few are chosen. This makes Bob and Matrix Chosen Ones among the Chosen Many that are the Guardians, as they were both accepted by Glitch.
• City Mouse: He has to be reminded on multiple occasions that Mainframe is not the Supercomputer, both in terms of technology and its sense of community.
• Determinator: "He is a Guardian. He will find a way to survive the Web, but he needs us to show him the way home."
• Deus Exit Machina:
  • His forced departure at the end of Season 2 is actually just one of several problems facing the heroes, but it makes the situation seem that much more hopeless and further emboldens Megabyte and Hexadecimal.
  • His sudden abduction by Hexadecimal at the end of "Megaframe" leaves the others without extra muscle during the assault on Megabyte's forces.
• Deuteragonist: In the latter half of season 3, with Enzo taking more of the lead role.
• Dude, Where's My Respect?: Despite being Mainframe's Guardian and a capable hero who has saved the system countless times, he tends to get little respect from a number of citizens, particularly Cecil and Frisket.
• Enraged by Idiocy: He's cool with fighting Users or viruses to protect Mainframe's inhabitants, since that's part of his function. What pisses him off is when those same inhabitants nearly get him deleted trying to "help" him.
• Fusion Dance: Bob merges with Glitch to create a portal from the Web to Mainframe. He also gets a lot of other cool powers in the process. Unfortunately, Glitch being damaged when they merged led to some problems later on...
• The Hero: For the first two seasons. As of season 3, he becomes more of a Messianic Archetype.
• Hero's Classic Car: Bob cruises around Mainframe in a red 262 convertible hovercar. When it's not having engine trouble, that is. When it reboots in a racing game, it takes the form of a 50s-style hotrod.
• Hollywood Tone-Deaf: He's a terrible singer. Yet an incredibly proficient guitar player.
• Imagination-Based Superpower: Glitch can do pretty much anything that it needs to do for the plot, including deciding for itself what it needs to do to advance the plot.
• Indy Ploy: Bob's favored method of dealing with any given situation.
• Last of His Kind: During season 4, Bob is the last Guardian that still has a Key tool. Additionally, he was the last Guardian to be infected by Daemon.
• Living Macguffin: Is considered such by Daemon, as he's the only Guardian whose Key tool hasn't fled her reach. By being fused with Glitch, Bob becomes the only Guardian left capable of opening portals throughout the Net, which is key to Daemon's plans of spreading her infection to isolated systems she can't normally access.
• Major Injury Underreaction: He badly burns his hand saving the system in Season 3 but barely flinches from it.
• Martial Pacifist: He repeatedly advocates trying to rehabilitate viruses rather than deleting them.
• Messianic Archetype: While he was always a Guardian sent by the more slick Supercomputer to "mend and defend," to protect Mainframe from games, glitches, and viruses... After he is betrayed and banished to the Web by the treacherous Megabyte in the Season 2 Finale, most characters speak of his memory with reverence, believing that "only Bob" can save them from Megabyte and the Supercomputer from Daemon. Most characters even describe his possible return as "believe in Bob" and "have faith in Bob."
  • His return to the show is treated almost like a Second Coming. His first act is to save the deathly ill AndrAIa by giving his life force to hers. His demeanor is much more humble, patient, and compassionate than his previous goofy, hot-headed persona. When he fuses with Glitch, he's bathed in gold and white. His primary powers become fixing and healing rather than fighting. In the final battle, his compassion cures Hexadecimal of her insanity, and it's his idea to allow the User to win the Game in Mainframe to allow the system crash and get rebooted by the User, which creates a kind of Rapture that restores Mainframe to its former glory and brings back all the sprites that were killed.
• My Car Hates Me: His is the type of car that just won't turn over in the most dire of situations.
• Nice Job Breaking It, Hero: His bickering with a superior kept Kilobyte from being deleted, giving him time to break free and upgrade to Gigabyte. He was then caught in a portal leading to Mainframe, which caused the destruction of one of the system's twin cities and caused Gigabyte to split into Megabyte and Hexadecimal.
• Only Friend: Or rather “the closest thing to a friend” to Hexadecimal. Despite her craziness and previous threats, Bob seemed to be the only character in the show to actually treat her with some sort of decency (leaving Mike the TV to help her recover after nearly getting deleted, healing her and rendering her sane after simply fixing her mask).
• Power Up Letdown: Bob does a lot of good when he merges with Glitch, but it starts taking a toll on his health because Glitch was damaged when they fused. Eventually, using his powers weakens him so much he's in danger of getting deleted.
• Present Absence: His absence for most of Season 3 is continually felt. Without him around, Megabyte is emboldened to begin taking Mainframe piece by piece, with many (even Hack and Slash) feeling no one can stop him. Losing Bob has a big effect on Dot's emotional state, which gets progressively worse as a result of other developments in the season. Enzo's attempts to fill the void are largely met with derision by Megabyte and citizens alike, as he is frequently compared poorly to Bob. After his transformation into a renegade, Matrix laments the idea of Bob being lost forever, but he also harbors a fear of the hero he idolized shunning him for what he had to become to survive.
• Put on a Bus: At the end of Season 2, he's rocketed into the Web by Megabyte; he's absent for most of Season 3 as a result, and Matrix and AndrAIa make it part of their mission to find him.
• Sensitive Guy and Manly Man: Post-time skip, Bob becomes the Sensitive Guy to Matrix's Manly Man. Matrix still hero-worships him, though.
• So Proud of You: After he reunites with Matrix, he tells him this, easing the latter's concerns about this.
• Status Quo Is God: Done rather infamously in Season 4. Despite his merge with Glitch being supposedly permanent, he eventually figures out how to unmerge them. This is followed by two Deus Ex Machinas in a row that return the Guardians' lost Keytools and revert Bob to his Season 1 design.
• Thou Shalt Not Kill: Considered a radical among Guardians for his advocacy of rehabilitation for viruses. It works for Hex, but by the end of Code of Honor, even Bob's starting to get tired of letting Megabyte live.
• Unwanted Assistance: Expresses annoyance in "AndrAIa" over two Binomes who attempted to "help" him in game by setting off an Earth-Shattering Kaboom (while still inside the given planet) and spouting irrelevant commands, respectively. He ends up teaching a refresher course to help other Mainframers learn what they should be doing in games.

Glitch

^{Click here to see Glitch's appearance in Season 4.}

Glitch is Bob's Keytool. It has the ability to become any object on command, as well as other powers such as analyzing the rules of a game. The exact limitations of Glitch's Imagination-Based Superpower abilities: it can only do one thing at a time, it's implied it cannot duplicate some of the rarer weapons Bob requisitions from Phong, it doesn't seem capable of turning into a sophisticated or large vehicle (though it can manage a hang-glider or a helicoptery thing to pull Bob out of a fall), and it does not have unlimited energy. Glitch is sentient, though it seems only a Guardian can understand its beeping language. Glitch was damaged at the end of season 2, making it unable to morph and project energy but still capable of scanning anything and everything. Later it merged with Bob, and was later unmerged and upgraded into Glitch 2.0 (whose exact capabilities are unknown).

---

• The Chooser of the One: Glitch will only allow those with the potential to be great Guardians to wield it.
• Empathic Weapon: Glitch is sentient and capable of activating on its own to protect its Guardian.
• Everything Sensor: Shows the rules of any game cube. It can also detect viruses.
• Fusion Dance: With Bob in season 3.
• Loyal Phlebotinum: It is extremely loyal to Bob. It accepts to merge with him so they can return to Mainframe and stop Daemon. Glitch' decision to abandon Bob to join the other Bob in My Two Bobs seems to seal the deal on which Bob is the original. Glitch is actually knowingly joining the fake Bob because in doing so it can retrieve the real Bob's missing code, and repair him, while revealing the fake as Megabyte.
• Swiss-Army Weapon: Glitch can morph into a ridiculous range of tools and weapons. And a lamppost one time.
• Super Wrist-Gadget: Glitch's default form is a small device that is mounted on Bob's wrist.
• The Unintelligible: Though it rarely speaks, Glitch's speech consists of beeps and whirring sounds.
• Take Up My Sword: Glitch was Dixon Green's (Bob's partner and mentor) Keytool. It passed to Bob when an upgrading Kilabyte killed her.
  • After Bob was cast into the Web, Glitch passed to Enzo (heavily damaged, see Wrecked Weapon) until they reunited with Bob towards the end of Season 3.
• True Sight: Glitch sees through Megabyte disguising himself as the "true" Bob and retakes the part of Bob's code that Megabyte absorbed when he crushed it. It then returns that code to Bob, restoring him to his full form and forcing Megabyte to reveal himself.
• Wrecked Weapon: Glitch is crushed by Megabyte at the end of season 2, rendering most of its functions useless. Until repaired by the other Keytools after unmerging with Bob.

Dot Matrix

Voiced by: Kathleen Barr, Pilar Escadón (Latin American Spanish dub)

The leader of Mainframe (she took over the position from, according to Word of God, an unseen sprite whom Phong represented sometime between the end of season 2 and the end of season 3). Dot is for most of the series Bob's main love interest. She owns Dot's Diner, a small diner that often served as headquarters to the heroes in the early seasons. Enzo is her little brother. Dot is known to be very organized and almost incapable of doing anything unless she has a plan. However, once she does have a plan, things usually go right.

---

• Amazonian Beauty: She has a very broad and muscular body, with great abs.
• Badass Bookworm: More often than not, the brains of the operations.
• Beauty, Brains, and Brawn: The Brains to AndrAIa's Beauty and Mouse's Brawn.
• Big Good: From season 3 onward, Dot takes over from Phong as Mainframe's Command.Com, leading the war effort against Megabyte's tyranny, and later, heading up Mainframe's resistance against Daemon.
• Big "NO!": In "Game Over" when Enzo, Frisket and AndrAIa lose a catastrophic game and are lost in the web because of it.
• Broken Bird: Was briefly hinted to be this in Season 2, but she became a more obvious example in Season 3, after losing Bob and Enzo.
• Clingy Jealous Girl: She gets annoyed when Mouse flirts with Bob.
• Cool Big Sis: For Enzo, until the time skip. Then she doesn't look so big to him anymore.
• Fire-Forged Friends: With Mouse. Dot initially can't stand Mouse due to her nearly getting Enzo deleted and her obvious thing for Bob, but they reach an understanding when they're forced to work together in "Gigabyte."

• The Heart: Definitely the heart and soul of the good guys for the first two seasons.

• Heroic BSoD: At the end of Season 2 when Bob gets shot into the web, she begins to go through this. And went further down after she believed Enzo was nullified. Even though she's happy to see Bob, Enzo (Matrix), AndrAIa, and Frisket back, she doesn't know if she has any fight in her left.
• Insecure Love Interest: Late Season 3, when Bob returns, Dot doesn't try to pursue him because she feels guilty for having given up on him ever coming back. Mouse snaps her out of it.
• The Lancer: In the early seasons mostly. In Bob's absence, she moves to Big Good.
• Ms. Fanservice: Is a very beautiful woman who often wears many flattering outfits, and gets a good bit of Male Gaze.
• My God, What Have I Done?: In the My Two Bobs movie, when she realizes she chose Megabyte (who was impersonating him) over the real Bob for rather shallow reasons (basically he looked like Bob used to) and very nearly married him. Doubles as Took a Level in Jerkass for some fans.
• Nice Girl: Despite her imperfections, Dot is very kind, supportive, sweet, and caring.
• Not So Above It All: Despite being usually one of the most level-headed members of the main cast, she was shown to enjoy pulling the occasional childish prank ("Racing the Clock"), and on the few occasions she has an argument with Bob, she adopts an attitude and behavior that even Season 1!Enzo finds childish ("The Tiff", "Wizards, Warriors and a Word from Our Sponsor").
• Promoted to Parent: As confirmed by the Season 4 flashbacks, Dot had to go from Cool Big Sis to Parental Substitute for Enzo following Welman's ultimately disastrous experiment in the twin city.
• Purely Aesthetic Glasses: Later on Dot adopted a pair of glasses despite no evidence that she actually needs them. They would pop up occasionally when she was reading early in the series but a lack of consistency kind of killed the idea.
• Small Girl, Big Gun: In "Web World Wars".
• The Smart Girl: Her main role, though in "The Tiff" she and Bob switch so she becomes the Action Girl and he becomes The Smart Guy.
• The Strategist: Dot is always the one who comes up with a plan.
• Team Mom: For Enzo on a personal level, and as a guiding force for the rest of the cast.
• Took a Level in Jerkass: In My Two Bobs she treats "Glitch Bob" badly, believing him to be a clone despite all they'd been through together. When she learns the "Original Bob" is Megabyte in disguise, she's horrified over how she acted.
• Wet Blanket Wife: Dot is Bob's Love Interest and Enzo's Cool Big Sis, but she's very serious and practical while the two boys start off more goofy and impulsive. In the first two seasons she's always the one to remind everyone they need a plan before rushing off into danger, and is pretty much the only sprite who seems to remember how dangerous Games can be (until poor Enzo lost an eye).
• What a Senseless Waste of Human Life: She doesn't take any pleasure in a victory over the virals in "Game Over".

Enzo Matrix

Voiced by: Jesse Moss (season one), Matthew Sinclair (seasons one and two), Christopher Gray (young Enzo, season three), Giacomo Baessato (Little Enzo), Danny McKinnon (flashback in season four), Carlos Díaz (Latin American Spanish dub, Seasons One and Two), Eduardo Garza (Latin American Spanish dub, Season Three)

Dot's Bratty Half-Pint brother who hero-worships Bob. He dreams of becoming a Guardian himself and enrolling at the Academy, and jumps at the opportunity to enter games and tussle with Viruses himself despite the danger of both of those tasks. He was eventually made a Guardian cadet by Bob. After this one was shot into the Web, Enzo saw himself forced take up the torch as Mainframe's Guardian. He struggled at first due to his inexperience and young age, but just as he was getting skilled, he had the misfortune of losing a game, which left him stranded in the Net and led to his development into an older anti-hero who usually goes by just "Matrix". See the entry for "The Renegade" below for more info. At the end of Season 3, Matrix accidentally leaves his icon in Game Sprite mode during a system reboot, causing the system to recreate young Enzo from an earlier backup (right after his "upgrade" to Guardian cadet) since he didn't read as being present. From that point forward, the two Enzos co-exist.

---

• All Up to You: The first arc of Season 3 deconstructs this. He's Mainframe's only hope against Megabyte, but he's just an inexperienced kid that virtually everyone thinks isn't up to the task. He frequently suffers self-doubt and depression over not measuring up. Megabyte even exploits this to further crush the townspeople's morale and sap their will to resist. Enzo does start to turn it around, though.
• Body Horror: He is turned into disembodied Vid Screens in Painted Windows. Fortunately, he makes it work to his advantage.
• Bratty Half-Pint: Enzo is often the cause of trouble due to his reckless nature and Hero Worship.
• Character Catchphrase: "Alphanumeric!"
• Child Soldier: Out of necessity once Megabyte banished Bob and began conquering Mainframe; he was the only sprite with the Guardian protocol and the only one who could use Glitch.
• Clones Are People, Too: Both Dot and Matrix consider the back-up copy of Enzo a little brother and part of their family.
• Divergent Character Evolution: Little Enzo develops differently than Matrix due to never having been subjected to years of survival in games. Hexadecimal also brings his father back, allowing them to bond with each other.
• Eye Scream: He has his eye shredded by a User in a Mortal Kombat style game.
• Foreshadowing: In Dot's Bad Future sequence from "Identity Crisis, Part 2," viewers see an older Enzo that's all muscled up and more of a jerk. He even has a scar over his right eye and wears an earring.
• Fantastic Racism: He experiences some against his green skin, oddly enough, due to Cyril's propaganda. While it was never an issue before, apparently Sprites with blue skin are seen as more heroic than those with green skin.
• Friendless Background: The destruction of the twin city left him the only small sprite in Mainframe, so he's often lonely whenever Bob and Dot are busy. This is changed after the episode AndrAIa in which the titular AI copies herself into Mainframe and joins Enzo there.
• Future Me Scares Me: Over the course of season 4, Enzo has a huge case of Hero Worship toward his future self, demanding to be called "Little Matrix." Over the course of the season, though, Enzo realizes all the hardships his adult self experienced and just how jaded and bitter they left him, and stops emulating him.
• The Glomp: Enzo does this to Bob so often that it's a Running Gag.
• The Hero: In Season 3 he replaces Bob as the hero and protagonist.
• Hero with Bad Publicity: Early in Season 3, thanks to Cyrus' propaganda and the general unwillingness of the Mainframers to accept anyone other than Bob as a Guardian. He and AndrAIa manage to turn this around somewhat, though.
• Hero-Worshipper: Enzo looks up to Bob. In season four, little Enzo latches on to his original self.
• Horrible Judge of Character: In the third episode Megabyte convinces him to take a package to Hexadecimal. He's somehow persuaded Megabyte would give him return business and be a good business partner.
• Keet: He's pretty energetic, befitting being The Baby of the Bunch.
• The Load: He's one early on, where he is quick to rush into a Game but fails to do anything useful. In one episode he rebooted into a Damsel in Distress. He was not happy with this.
• Nice Job Breaking It, Hero: He once turned everyone in Mainframe into absolute idiots, then had to win a Game with them all in that state.
• Odd Friendship: Little Enzo quickly befriends a cured Hexadecimal, much to Matrix's chagrin.
• Only Friend: The game sprite AndrAIa becomes his only friend after she enters Mainframe. Hexadecimal of all people fills this role for Little Enzo.
• Running Gag: His typical reaction upon seeing Bob was to shout, "Bob!" and tackle the Guardian to the ground.
• Sucksessor: He serves for one for Bob in season 3 due to Cyril's propaganda against him making him seem weak and incompetent compared to the Guardian himself.
• Take Up My Sword: Becomes Mainframe's Guardian after Bob is lost in the Web. And he fails.
• Tag Along Kid: He starts as one, but develops into a capable Game player in his own right.
• Taught by Experience: Enzo was able to survive as a replacement Guardian thanks to his always tagging along on Bob's adventures.
• What the Hell, Hero?: He calls his older self out for having become no different than Megabyte in Number 7. Later, Little Enzo calls Matrix out on being a bitter and jaded person.

Mouse

Voiced by: Louise Vallance, Rocío Prado (Latin American Spanish dub)

Mouse was first mentioned as an old "associate" of Bob's before showing up as a mercenary working for Megabyte. She was quick to join the heroes, however, after Megabyte double-crossed her. She managed to simultaneously be an Action Girl while mostly taking Dot's place as The Smart Girl.

---

• Action Girl: Just like practically every other female in the series.
• Amazonian Beauty: Mouse is a very muscular and beautiful woman who has no trouble attracting the fancy of many male characters in the show. Her musculature is especially pronounced in later episodes.
• Ascended Extra: Makes a one-off appearance in Season 1 before returning in the concluding arc of Season 2.
• Beauty, Brains, and Brawn: The Brawn to AndrAIa's Beauty and Dot's Brains.
• Character Catchphrase: Tends to call everyone "Sugah".
• Chekhov's Gun: In the Season 2 Finale, Mouse informs Megabyte that she's not only fixed the glitch to the Web, but sealed it so nothing can find its way back in. Then Megabyte sends Bob into the Web. Most characters hold out hope that Bob will find a way back in Season 3, but it isn't until the party tries to return to Mainframe through the Web that they encounter one of Mouse's traps.
• Cool Ship: Not like Capacitor's, hers is more an airborne warship.
• The Cracker: Mouse is a hacking program. Within the context of the Net, this makes her equal parts freelance mercenary and Classy Cat-Burglar.
• Cute Little Fangs: Odds are if you're seeing these, Mouse is pretty pissed off.
• Dating Catwoman: It's suggested that Mouse and Bob had this relationship before he arrived in Mainframe. While he was arresting her when she tried to hack into the Supercomputer, Mouse flirted with him constantly.
• Dropped a Bridge on Him: The Code of Honor webcomic kills her and Ray off in a fairly mean-spirited manner, without much of a sendoff past "Where's Mouse and Ray? Crap."
  • Although the two of them, as well as Turbo, turn out to be not really dead. They're still never seen again in the comic, but it's implied that the three of them came back after Gnosis was dealt with.
• The Dreaded: Her hacking skills are second-to-none. When the crew of the Crimson Binome tries to hack the Firewall to get back to Mainframe, they almost give up completely knowing she personally programmed it.
  Matrix: We might've been able to sneak past Megabyte, or even Hexadecimal...but Mouse?!
• Everyone Has Standards: In "The Great Brain Robbery," she had no problem helping Megabyte hijack Bob's (then Enzo's) brain to access the Supercomputer. But learning Megabyte intended to delete a little boy, and her with him? Nu uh, sugar.
• Exactly What It Says on the Tin: The name of her ship? "Ship".
• Fire-Forged Friends: With Dot. Dot initially can't stand her, and Mouse was only too happy to troll her, but they reach an understanding when Dot saves her life.
• Genius Bruiser: Hacks systems just as well as she fights.
• Head-Turning Beauty: She's extremely attractive, and her very first scene leaves Megabyte and his minions distracted by her Supermodel Strut.
• Heel–Face Turn: Never exactly evil, but she went from a thief with some standards to a loyal ally.
• Impossibly-Compact Folding: She uses a full length katana. Which she keeps in an ankle holster. Somehow.
• Katanas Are Just Better: Her weapon of choice, and she even laments not having anywhere to put it while wearing her bridesmaid dress.
• Leitmotif: A rising four-note sequence.
• Masculine Girl, Feminine Boy: The masculine girl to Ray's feminine boy.
• Nice Job Breaking It, Hero: While it was very satisfying seeing her send Megabyte into the web, instead of letting him infiltrate the Super Computer, this allows him to come back disguised as Bob and with Trojan Horse abilities. As if she doesn't feel bad enough for being used so many times.
• Noodle Incident: Bob once arrested her for hacking into the Supercomputer. Whatever she did to be thrown in Captain Capacitor's brig and did to escape are given even fewer details.
• Number Two: In the war against Megabyte, Mouse ends up becoming Dot's right-hand woman.
• Playful Hacker: She hacks the Principal Office to take down its shields with a wink, mostly for fun.
• Shaped Like Itself: Mouse's ship is called "Ship". Go figure.
• Sitcom Arch-Nemesis: Is this to Dot at first, before Mouse settles down in Mainframe and they become friends.
• Southern-Fried Genius: Has the accent, and is very intelligent.
• Statuesque Stunner: She's almost as tall as Bob.
• Stealth Hi/Bye: A talent of hers. Bob used something she left behind to pull a similar trick in "The Crimson Binome".
• Supermodel Strut: She walks with a confident strut that has her hips swaying in a seductive manner. Megabyte even gets distracted by it when they meet for the first time.
• Unmoving Plaid: A variety. her hair and eyebrows have a constant orange-colored "white noise" pattern.
• Unusual Eyebrows: They appear to be attached to her hair.
• Unwitting Instigator of Doom: During the Web invasion, Mouse set up a series of booby traps to protect Mainframe from further incursions. It's not a problem for the heroes, unless they happen to be on a pirate ship covered in dead Web creature scales.
• Unwitting Pawn: Twice, which cemented her decision to join the good guys.
• Wild Card: Originally she was a truly neutral party, working for whoever paid her. Enough betrayals by Megabyte turned her fully to the side of good.

Phong

Voiced by: Michael Donovan, César Arias (Latin American Spanish dub)

The oldest and wisest sprite in Mainframe, who lives in the Principal Office and oversees the system. A frequent target of Megabyte's schemes, nevertheless he does what he can in order to stop him with the help of the others.

---

• Big Good: In seasons 1 and 2; Dot later takes over this role.
• Character Catchphrase: "Oh dear" and, to a lesser extent, "Yadda yadda."
• Crazy-Prepared: He had a set of Power Rangers-esque robots built in case of a giant null monster attack, which later happened.
• Determinator: "I will fight you to the last, virus."
• Gambit Roulette: Apparently, he let Enzo use the Read-Only Room knowing full well what would probably happen to Mainframe, in order to teach him a lesson.
• Heroic Sacrifice: In the flashbacks to "Megaframe," as the virals break into the Principal Office, Phong stays behind to give Dot and the others time to evacuate. He doesn't die, of course, but he didn't know that and appeared quite ready for the worst possible result.
• Incorruptible Pure Pureness: In a way; as read-only memory, he's totally immune to infection from all but the most powerful viruses.
• Incredibly Lame Pun: People had to beat him in Pong to get his advice.
• Meaningful Name: He seems to be named after Phong shading, which is especially prominent on his shiny body.
• Mission Control: His main function for the good guys.
• Non-Action Guy: Most of the time. When he does participate in something, it is usually because the situation is dire.
• Off with His Head!: Megabyte severs his head and tortures it in Season 3.
• Running Gag: He often puts a damper on Bob's enthusiasm by reminding him that "This is not the Supercomputer" and their resources for fighting Viruses are limited. This is subverted when eventually, he has exactly what they need to fight a giant Null monster - Combining mechas.
• Took a Level in Kindness: As the series progressed he went from a somewhat obstructive Trickster Mentor to a genuinely helpful Mission Control who even took part in defending the system from some games.
• Trickster Mentor: In non-serious cases in earlier seasons, the person seeking advice would have to win a game of Pong against him first.

AndrAIa (Unmarked spoilers!)

^{Click here to see AndrAIa's appearance post-time skip.}

Voiced by: Andrea Libman (young), Sharon Alexander (adult), Christine Byrd (Latin American Spanish dub, young), Connie Madera (Latin American Spanish dub, adult)

Originally a game sprite, AndrAIa met young Enzo in an aquatic game and they became friends. As the game ended, she attached a copy of her data to Enzo's icon so that said copy would leave the game with Enzo and could stay with him. Aged up along with Enzo, becoming an Action Girl and Love Interest.

---

• Action Girl: She was already this in the game where she originated, but growing up with Matrix made her even more this trope.
• Amazonian Beauty: She grows up to be very muscular and statuesque, and it's pretty much impossible for any man not to fall head over heels for her.
• Badass in Distress: She can hold her own in a fight, but every now and again she needs help.
• Beauty, Brains, and Brawn: The Beauty to Dot's Brain and Mouse's Brawn, as an adult.
• Beta Couple: In contrast to Bob and Dot's Will They or Won't They?, Matrix and AndrAIa become a committed couple during the Season 3 time skip.
• Childhood Friend Romance: She and Enzo are close friends as kids, and become lovers post-time skip.
• Dude Magnet: Pretty much every guy who meets her post-time skip openly admires or lusts after her.
• Fish out of Water: Almost literally. Her original form is that of an aquatic mermaid-like creature. She also displays the trope properly in her child form, though after the timeskip she's grown out of it.
• Foreshadowing: In a few season two episodes, she reboots into biker chicks. Post-time skip, she grows up into a biker.
• The Glomp: Enzo gets a taste of his own medicine in "To Mend and Defend" when AndrAIa glomps him the way he used to do to Bob.
• Greater Need Than Mine:
  • In her debut episode, she helps Enzo win the Game so he can return to Mainframe with his friends, knowing she'll be deleted with the Game and without any guarantee that a backup of her AI data will reboot into his world.
  • Later, she stops Mouse from testing an adaptor pin in a Game, reasoning that if it doesn't work AndrAIa can survive in game environments as a game sprite, while Mouse would just be deleted or nullified.
• The Heart: Took over the role from Dot in Season 3, after this one was (temporarily) removed from the cast and developed into more of a Broken Bird.

• Hell-Bent for Leather: Again, adult AndrAIa.
• Literal-Minded: "Now all we can do is sit and wait". "I will stand, if that's okay with you." Grew out of it over the time skip.
• Love at First Sight: Falls in love with Enzo very soon after meeting him. She outright says the trope name when discussing love with Daemon.
• Luckily, My Shield Will Protect Me: After the timeskip, her fins have grown strong enough to stop shrapnel and such, on top of being able to extend them.
• Manic Pixie Dream Girl: Young AndrAIa is at least borderline, in a Puppy Love kind of way; she's not as energetic or spontaneous as a typical Manic Pixie Dream Girl but she's perky, has a number of odd quirks due to her origin as a Game Sprite, and is devoted to Enzo from the beginning. As an adult, though, she no longer fits the personality type, having become too calm to qualify and lost her Fish out of Water idiosyncrasies.
• Meaningful Name: She's a sentient game sprite with the "AI" in her name in caps.
• Morality Chain: She's the only reason Matrix didn't become a complete and utter psychopath during the time skip. (Something he practically admits near the end of "Number 7.") Any time she's separated from him or incapacitated, he gets really, really ill-tempered, even compared to his normal self. At one point he is seen working this frustration off in a Game. This was a bad time to be a User.
• Morality Pet: She tends to bring out the best in the men around her. Matrix, the Crimson Binome, and Ray Tracer (though he's a Nice Guy anyway) are all on their best behavior around her, and often act uncharacteristically selfless for her sake during Season 3.
• Obfuscating Stupidity: When they first met, Enzo claimed to be a Guardian to impress her and was very reluctant to tell her the truth. Despite the obvious, though, she always referred to him as "Guardian." In Season 4, however, AndrAIa reveals that she always knew the truth on account of her superior hearing. She just pretended to believe the lie because she was in love.
• Official Couple: With Matrix post-time skip.
• The Paralyzer: Her nails, which break off like a bee's barb to increase the effect. As she grows older she learns to shoot them.
• Prongs of Poseidon: She picks up a trident either from a game or from somewhere in the net in between games.
• Sarcasm-Blind: She doesn't understand the concept of sarcasm when she's little. After she's grown into an adult, she's no longer blind to it.
• Satellite Love Interest: Averted. Narratively, she was created so Enzo could have a friend his own age. In-universe, she's a game sprite who joined the Mainframe crew just to be with Enzo, and admits she considers "home" wherever he is. Yet, she quickly becomes a main character in her own right, and post-time skip she develops a strong, amiable personality and moral compass outside of Enzo. She isn't afraid to challenge or disagree with him, split up when necessary, gather information and resources herself, and even make friends and allies when he's not around (much to his jealousy).
• Secret Secret-Keeper: She knew for a long time that when she and Enzo met, he wasn't a Guardian/Guardian Cadet, as she has really acute hearing so she could hear all the times Bob and Enzo "quietly" discussed Enzo lying about his Guardian status.
• Statuesque Stunner: Post-time skip, she becomes very tall and very fit. She's only shorter than Matrix and Mouse, but that's only because they're both HUGE.
• Stripperiffic: Adult AndrAIa's skintight outfit has gotten a fair bit of Male Gaze.
• Super-Senses: Her hearing may be on par with Frisket's.
• Took a Level in Badass: While she was designed to be an Action Girl in the game that originated her, her very first scene had her getting one-shotted by the User within seconds. After the time skip, however, she was shown to be far more capable, as a result of being older and more experienced, as well as gaining a trident and the ability to shoot her fingernails.
• Undying Loyalty: Devoted to Enzo through thick and thin.
• Violently Protective Girlfriend: Downplayed. While she never has to resort to violence, any time Enzo is threatened pre-time skip (usually by Metabyte), she doesn't hesitate to stand between him and trouble with a weapon drawn.
• What the Hell, Hero?: She loves Matrix completely, but she isn't above telling him off when his jerky behavior goes too far.
• Year Inside, Hour Outside: Her and Matrix's appearances in season 3 suggest that time within the games works this way.
• Youthful Freckles: Has them, despite having a more reserved personality than most examples (ironically, the far more hyper Enzo doesn't have them). They're still there after the time skip.

The Renegade (Unmarked Spoilers!)

Voiced by: Paul Dobson, Octavio Rojas (Latin American Spanish dub)

Originally Dot's Bratty Half-Pint brother. In the 3rd season, he underwent a Plot-Relevant Age-Up into a super strong badass with a short fuse, a hatred of viruses, and a homicidal hatred of Megabyte in particular. The adult Enzo has a copy of Bob's Guardian code, meaning that he has technically all the immunities a Guardian has to the web and viral infections, although he never had any Guardian training. The lack of training, however, does not make him any less dangerous (Heck, it probably makes him more dangerous). He takes on the name "Matrix" and it sticks when a younger copy of him is created at the end of season 3.

---

• Alternative-Self Name-Change: With the creation of a second Enzo following a system restore, the original Enzo decides to go by the name Matrix from that point on.
• Always Save the Girl: Deconstructed. In late Season 3, when AndrAI's energy is stolen by a Web creature, Matrix's bull-headed determination to save her no matter what nearly gets himself and the crew killed multiple times. In Daemon Rising his desire to save AndrAIa and get revenge on Daemon only causes both him and Mouse to get brainwashed by Daemon.
• Anti-Hero Substitute: Deconstructed. Enzo grows from a cheerful, naive young sprite into the big, tough badass Matrix, but everybody keeps telling him how being a big, tough badass does not compensate for being a jerk, and his hotheaded actions put AndrAIa, the love of his life, in mortal danger. A recurring theme of season three is the fact that, for all his efforts to reunite with his family and Mainframe, he knows that they would be disgusted and repulsed by what he has become.
• Badass Normal: Even without Gun and Glitch he's a force to be reckoned with, as Megabyte learned the hard way.
• Be Careful What You Wish For: As a kid, he loved games and thought they were fun despite the many dangers they bring. When he becomes a full-time guardian, he loses an eye inside a game. Then he gets lost in the Net for a year, playing nothing but games to try to return home. By the time he finally does, he no longer considers games fun. His younger copy still loves them, however.
• Big Brother Instinct: Though he doesn't like to show it, he has this toward Little Enzo, treating him as a little brother.
• The Big Guy: Matrix is big and strong enough to punch a dent in Megabyte, or a wall.
• Big Little Brother: Averted, sort of. It's implied that because of the time difference in games, Matrix is actually older than Dot.
• Break the Cutie: Losing Bob, being promoted to Guardian, and enduring a hopeless PR battle against Megabyte was hard enough on poor Enzo. But then losing a Game (and an eye), and being lost in the Net for years sealed the deal.
• Character Catchphrase: "You got a deletion wish?"
• Charles Atlas Superpower: After everything he went through in the games, Matrix is tough enough to fight Megabyte evenly.
• The Chosen One: Turbo calls Matrix one upon seeing Glitch with him, as keytools select their guardians, and few are chosen.
• Combat Pragmatist: Mostly in his "interactions" with Megabyte, Matrix dents his chest, gouges his gut, breaks his claws, and punches him in the gut wound, repeatedly and that is when he doesn't just shoot 'em. Although he did get an Honor Before Reason moment when Megabyte goaded him into putting down his gun and just using fisticuffs. This quickly ended when he saw that Megabyte had no intention of fighting fair.
• Crazy Jealous Guy: He does not appreciate anyone hitting on his girlfriend even though he knows she'd never leave him.
• Cutting the Knot: Post-time skip, Matrix doesn't have much patience for fuss and deliberation. Special mention goes to ignoring Ray Tracer to follow a Web creature through an electrical storm that nearly destroys the Saucy Mare.
• Damned by Faint Praise: To himself, no less. In "Number 7," Matrix has a dream in which his younger self confronts him about becoming just like Megabyte, and accuses him of not loving or caring about anyone. Matrix can only weakly respond, "That's not true! I love AndrAIa!"
• Dark Is Not Evil: Matrix has the looks of a dark themed Anti-Hero, but he is still the same Enzo.
• Do Not Call Me "Paul": Post-time skip, he really hates when people call him Enzo.
• Electronic Eyes: Matrix's prosthetic eye lets him detect viruses, aim his gun, and use telescopic vision.
• Eyepatch After Time Skip and Eyepatch of Power: Cybernetic eye instead of an eyepatch, but the trope is still in full effect. Those games were not kind to him. Kind of a variation in that Enzo losing the eye happens on-screen, in his last scene before the time skip.
• Eye Scream: What led to the trope above. Note that the scene where his eye was cut out was surprisingly relatively bloody...and happened when he was still a little boy...
• Fantastic Racism: The adult Matrix has a vicious hatred for viruses, at one point scoffing at a felled virus's pleas for mercy before deleting him. That said, Megabyte gave him many a good reason to hate viruses.
  Virus: Please, renegade! Mercy!
  Matrix: Mercy? To a virus? Never. [Boom, Headshot!]
• Foreshadowing: In Dot's Bad Future sequence from "Identity Crisis, Part 2," viewers see an older Enzo that's all muscled up and more of a jerk. He even has a scar over his right eye and wears an earring.
• Future Badass: It's almost hard to believe that Matrix and Enzo are the same person.
• Gentle Giant: According to AndrAIa, Matrix is this once you get to know him. Those who had to face him as enemies would beg to differ on the gentle part, though.
• The Glomp: He nearly glomped Bob again after finding him in the Web, though Bob sensibly pointed out he was too big for that now.
• Good is Not Nice: He's a bit of a jerk due to past trauma. However, Matrix still believes in helping people as long as it doesn't interfere with his own goals.
• Good Is Not Soft: He lacks Bob's mercy when it comes to viruses.
• Green-Eyed Monster: He is extremely jealous of Ray's attraction to AndrAIa in season 3.
• Hates Being Touched: It's subtle, but close observation shows that Matrix tends to either flinch away from people trying to touch him or outright push them away - sometimes quite violently. He has at least once responded to sudden, unexpected physical contact by pulling his gun. In fact, it seems like Matrix doesn't even like people standing close to him in general, to the point of outright nudging a binome backwards with his boot when he got too close. The only regular exception to this seems to be his girlfriend AndrAIa, with whom he is physically affectionate with.
• The Hero: In Season 3, including after Bob comes back. Firmly The Lancer in season 4 though.
  • Sociopathic Hero: Matrix has moments like this, but that's more due to trying to hide his softer side. Still, Matrix has no qualms about killing his enemies, much to the dismay of both his allies and younger self.
• Heroes Love Dogs: One thing that hasn't changed about him is the love for his dog.
• Hero-Worshipper: Both versions of Enzo look up to Bob. In season four, little Enzo latches on to his original self.
• He Who Fights Monsters: He never took the presence of Megabyte too seriously, until Megabyte finally took over Mainframe, exiled Bob into the Web, and pushed Enzo into despair until he was trapped in the games. When Enzo came back much older and much more serious, killing Megabyte was all he could think of. In the episode "Number 7," he ended up in a simulation of Mainframe, where he rebooted in Megabyte's body and easily played the part unconsciously. That same episode also shows that Matrix suffers from a lot of self-loathing over what he's become and fears he's truly become a monster like Megabyte.
• Hidden Heart of Gold: In "Icons," he delivers "The Reason You Suck" Speech to the binomes of a devastated system for being too scared to go into games and then storms off. When AndrAIa catches up with him, he asks how many signed up. Apparently, the tactic works great in getting people to join the cause.
• His Own Worst Enemy: He justifies becoming a muscle-bound renegade as a means to defend his loved ones and home. However, "Number 7" reveals he actually carries around a lot of self-loathing about what he's become and fears he's really just a selfish, unloving sprite driven by hatred. The same episode also shows him succumbing to despair over his lack of control in game-hopping, though he shakes it off in the end and takes charge.
• I Got Bigger: Holy crap did he ever. Enzo was half the size of Bob while Matrix is taller than all but Megabyte.
• I Hate Past Me: Matrix is greatly ashamed by Little Enzo and finds him to be an annoying Load. However, part of this is due to his own self-loathing and fear he'll never be able to reintegrate into Mainframe again, and that young Enzo makes Matrix see the flaws into the person he's grown into, by noticing all the qualities Enzo had that he's lost. The trope gets inverted in season 4, where Enzo tells Matrix that he hopes to never grow up to be like him because of how callous Matrix is.
• Irony: Enzo had to become the ruthless Anti-Hero Substitute Matrix to survive the Games to return home to Mainframe... yet his new ruthless antihero nature is exactly what prevents him from fitting in in the very home he's trying to return to.
• It's All My Fault: Blames himself after AndrAIa falls deathly ill, since his jealousy prevented him from being there to protect her.
• Jerkass Has a Point: He hates viruses, putting him at odds with Bob's belief that viruses can be benign. But aside from Hexadecimal, every virus Matrix has encountered proved to be evil, and Hex still nearly destroyed Mainframe more than once. Not to mention him letting Megabyte live proved to be a big mistake.
• Jerk with a Heart of Gold: After the timeskip he becomes one.
• Last-Name Basis: Matrix is so ashamed of the goofy kid he used to be that he insists that everyone refer to him by his last name rather than Enzo.
• Macross Missile Massacre: Matrix's bike, which can launch dozens of missiles in every direction all at once.
• Morality Chain:
  • AndrAIa. Without AndrAIa to be his friend and eventually, his girlfriend, Matrix would have spun off the deep end long ago. Even then, he is very often a Jerkass to everyone besides her.
  • In season 4, Young Enzo acts as this to him, as Enzo's disapproval of his older self shames Matrix into acting better.
• More Dakka: Gun's "Death Blossom" mode consists of the gun tagging everyone in the room, before spinning in mid-air on its own randomly. It's also a Shout-Out to The Last Starfighter.
• Mr. Fanservice: Matrix is definitely the most sexualized male character on the show. He is a tall, extremely muscular, and handsome young man with tattoos and scars so, if you're into tortured bad boys Matrix is the one for you! notably, several Games involve him rebooting forms that are shirtless and are in general scantily-clad.
• Muscles Are Meaningful: Matrix is big and buff, and it shows when he takes on Megabyte and wins.
• My Greatest Failure: Losing a game and failing to protect Mainframe when it needed him the most, which led to him becoming disgusted by his weakness and turning himself into the muscular, gun-toting Matrix.
• Nice Job Breaking It, Hero: His attempt to rescue AndrAIa against all odds ends up delivering Mouse right into Daemon's hands, causing Mouse to dismantle all of Mainframe's defenses against her.
• No Social Skills: Spending the equivalent of roughly ten years in near-constant combat scenarios with only his girlfriend and feral dog for company has left Matrix with little in the way of social skills or intelligence, which is quiet sad considering how social and friendly he was as a kid. Matrix is rough, blunt, quick to anger, and cold with others, even those he genuinely cares about. This becomes a legitimate issue when he returns to Mainframe, as he has a hard time rebuilding old relationships.
• Outgrowing the Childish Name: After growing up in the games, Matrix insists on being addressed on a Last-Name Basis, having become cynical and hating the naïve kid he used to be.
• Red Eyes, Take Warning: When his golden eye glows red, he's gunning for you.
• Shaped Like Itself: Matrix nicknamed his gun Gun. Yeah.
• Shell-Shocked Veteran: Going through the games clearly took a toll on Matrix's sanity. He is quick to react to anything that startles him by pulling out Gun, which shames him deeply when Bob witnesses one such outburst.
• Silly Rabbit, Idealism Is for Kids!: After he gets trapped in one of the games, he develops this outlook on life.
• Sour Outside, Sad Inside: Matrix is a rough guy on the surface to most people but his closest friends, but on the inside he has a lot of self-loathing over what he's become.
• Stealth Pun: It was all fun and Games until Enzo lost an eye...
• Still Wearing the Old Colors: That orange stripe on Matrix's shoulder? That's from the Guardian uniform he got as Enzo.
• Stranger in a Familiar Land: While searching for a way back to Mainframe, Matrix worries that the ruthless renegade he's become won't fit in with the home of his youth. Subverted once they return Mainframe, which is reduced to a post-apocalyptic hellhole thanks to Megabyte's tyranny. Double-subverted when the system crashes and Mainframe is restored to its pristine old self. The Season 3 Series Fauxnale implies, and the Un-Canceled Season 4 confirms, that while Matrix is happy to be home, he will never feel truly comfortable or fit in there the way he did as a kid.
• Strong and Skilled: While one could mistake Matrix for Unskilled, but Strong. considering his size and proportionate strength, he's seen competently wielding many different weapons after the Time Skip, when he isn't using Boxing, Kung-Fu, or even Wrestling to put the hurt on his enemies. Assuming he doesn't just shoot them, considering how much of a Combat Pragmatist he is.
• Strong Family Resemblance: Aside from a few different accessories (and, of course, his size) Matrix looks almost exactly like his father, Wellman Matrix.
• Super-Strength: For starters, he punches Megabyte with enough force to send him flying across the room and bash a big dent in his chest.
• Taught by Experience: Enzo was able to survive as a replacement Guardian thanks to his always tagging along on Bob's adventures. Taken to the extreme while he was Game Hopping, where he spent several years worth of time fighting for his life, coming out stronger for it.
• That Man Is Dead: Matrix repeatedly refuses to go by his first name because he's ashamed of the goofy kid he once was. The name is later taken up by Little Enzo.
• Took a Level in Badass: Matrix went from being the series' Bratty Half-Pint to being tough enough to take Megabyte on in a straight-up fight.
• Took a Level in Cynic: Used as his Establishing Character Moment post-timeskip, where he loudly trash talks a weak band of binomes in a nearly-destroyed system. However, this is subverted when afterwards he and AndrAIa reveal his attitude was a ruse to convince more binomes to volunteer to learn how to be trained in game combat.
• Took a Level in Jerkass: During "Daemon Rising" he goes from Renegade with a Hidden Heart of Gold, to a trigger-happy spoiled brat. Thankfully, he gets better by "My Two Bobs".
• Totally Radical: In his youth, Enzo spat lots of lines like this: "ALPHANUMERIC!", "PIXELACIOUS!", "TOTALLY RANDOM!". After he grew up, he considers these lines embarrassing.
• Tragic Bigot: Following the Time Skip, Enzo has an intense hatred towards all viruses, even those that are friendly.
• Trigger-Happy: Matrix is quick to draw his gun and this sometime leads to Family-Unfriendly Death.
• Unstoppable Rage: Matrix isn't to be provoked. Megabyte does it and ends up being tackled through a wall and having a dent punched into his chest.
• Used to Be a Sweet Kid: When Matrix was a kid, he was upbeat and enthusiastic. After he compiled into an adult, he became a brooding violent renegade.
• Vague Age: Even when without the Year Inside, Hour Outside issue of the Games, just how old Matrix (and AndrAIa) are supposed to be is unclear. Various official sources listed him as (the equivalent of) 22, but Gavin Blair has stated he is only 19 (which raises the question of what 19yos was Gavin Blair looking at?!). He is shown ordering what is presumably alcohol in one episode, meaning Matrix is either of legal drinking age... or big and scary enough to get away with drinking underage. Both are equally possible.
• Walking Spoiler: Just seeing his character model makes it obvious that something traumatic happens to Enzo.
• "Well Done, Son" Guy: Shows traces of this after Bob is rescued. While he is thrilled to see Bob again, he is concerned that the Guardian will judge him harshly for what he had to do to survive. Unsurprisingly, Bob is actually proud of him.
• What Have I Become?: A recurring theme from season 3 onwards was Matrix struggling with his self-hatred towards not just towards his past behavior, but his current self as well, and his repeated self-castigation over the fact that the choices he's made to survive have turned him into a person that his friends and family from Mainframe would be disgusted by.
• What the Hell, Hero?: Matrix gets chewed out by other characters many times for his jerkish, reckless, and/or ruthless behavior.
• Why Don't Ya Just Shoot Him?: His favored response to most situations, though he doesn't get to actually do it most of the time. This is used to set up an Austin Powers-themed Game where Matrix, in the form of Dr. Evil, decides to forgo the deathtrap and just put a bullet in the User. "Gun, command line: full delete" has been the last words heard by many a virus.
• Worf Had the Flu: He gets beaten up by a degraded sprite in Web Riders on the Storm when he would soon take Megabyte in hand-to-hand combat, but that's because he had donated probably most of his blood-analog to AndrAIa.
• Year Inside, Hour Outside: His and AndrAIa's appearances in season 3 suggest that time within the games works this way. He ages to be even older than Dot after spending a year within the games.
• Younger Than They Look: While difference sources vary on what Matrix's official age is, the oldest possible answer is 22. Considering he looks AT LEAST 25, this is a surprising.

Supporting Cast

Frisket

Enzo's dog. He has been known to chew tanks and growl at Bob.

---

• Amplified Animal Aptitude: Frisket can't speak at all (the closest he ever comes is a human-like snicker once in a while) and acts like a dog in most respects, but occasionally displays problem-solving abilities comparable to the humanoid sprites. For instance, there's the below example of him driving a car through a minefield in "Bad Bob".
• Evil-Detecting Dog: Goes with his incredible sense of smell.
• Made of Iron: Frisket's tougher than any of the other heroes.
• The Nose Knows: Can sniff out a virus under any circumstances.
  • In Bad Bob, he sniffs out land mines and steers around them. At the same time.
• Super-Strength: He once got a hold of an Armored Binome Carrier and repeatedly smashed it around like a chew toy. On more than one occasion he anchors ABCs from taking off by sinking his teeth into the bumper, up until it tears right off. He also caught a cannonball with his teeth once.
• Team Pet: Possibly one of the most intimidating examples of this trope ever.
• Undying Loyalty: Enzo once referred to him as feral, and he really does do as he pleases in general, but when it comes to Enzo? Not only would he face Megabyte, he'd face his superpowered upgrade, Gigabyte.

Ray Tracer

Voiced by: Donal Gibson, Gerardo Reyero (Latin American Spanish dub)

A type of enhanced Search Engine, Ray meets Matrix and AndrAIa in a desert system where he is being detained by the authorities. He ends up joining their group because he can guide them through the Web, although he simultaneously causes Matrix much grief by flirting with AndrAIa. But in the end, Matrix accepts him. Ray later becomes the love interest of Mouse.

---

• Amazon Chaser: Two women he's shown attraction to: AndrAIa and Mouse.
• Awesome Aussie: Where he got the accent isn't explained.
• Captain Ersatz: Ray (especially when flying through the web) is an obvious homage to the Silver Surfer.
• Damsel in Distress: Apparently loves rescuing these. Uses the phrase verbatim when he first sees AndrAIa.
• Demoted to Extra: Season 4. Seriously, the only times he appears on-screen are brief, silent cameos. This was largely due to his voice actor being unavailable. And that his powers were plot breaking in the Daemon struggle.
• The Dulcinea Effect: One episode after meeting AndrAIa, he says he'd do anything to save her. Including some borderline suicidal actions. Like disagreeing with Matrix.
• Empathic Weapon: Or rather, Empathic Surfboard- er, Surfbaud.
• Love Triangle: Sort of. AndrAIa either doesn't notice he likes her or doesn't really care. Either way, it's fairly obvious that she stays with Matrix. Also note that while Ray initially and genuinely flirts with her, that's before he sees she's in a committed relationship. He otherwise backs off save some compliments, but Matrix misinterprets it out of jealousy.
• Nice Guy: In sharp contrast to Matrix.
• Pair the Spares: He and Mouse hook up in the Season 3 Series Fauxnale.
• Product Placement: He has Motorola logo on his waist.
• Rescue Romance: Averted. He rescues and flirts with AndrAIa when they first meet, but she's in a committed relationship with Matrix, and Ray doesn't pursue her further (beyond some friendly flirting) after learning she's taken.
• Sky Surfing: Has flown his surfboard all over the Net and even through dangerous corners of the Web.
• Synchronization: Whenever his surfboard is hit, he will be incapacitated.

Mike the TV

Voiced by: Michael Donovan, Ernesto Lezama (Latin American Spanish dub, Seasons One and Two), Martín Soto (Latin American Spanish dub, Season Three)

Mike is Bob's TV. Bob could never turn him off because the remote ran away. Mike talks a LOT. All the time. Usually reciting Stock Phrases, or advertisements he used to show. Around Mainframe, Mike is the closest thing to a news anchor, presenting news, narrating documentaries, and other such jobs in the visual media (including speaking with the drawl often associated with televangelists, while infected by Daemon). Mike has a great talent at annoying other characters (although the supervirus Daemon seemed to enjoy his company). He's a coward who will constantly remind people that he's a personal friend of Bob.

---

• ...And 99¢: The Bucket'O'Nothing ad has him state that it's available for only ninety-nine, ninety-nine, ninety-nine.
• Brainwashed and Crazy: Is the first character we see infected and mind controlled by Daemon. It doesn't actually do much to change the way he acts beyond making him a kiss up to her.
• Butt-Monkey: He often gets scared out of his wits to put over the threat(s) of the episode.
• Cloud Cuckoolanders Minder: After "Painted Windows," Bob gives Mike TV the unenviable task of keeping Hexadecimal entertained so she won't cause havoc around Mainframe. It works for a while... until he accidentally shatters her looking glass.
• Cool and Unusual Punishment/Fate Worse than Death: From "Wizards, Warriors, And A Word From Our Sponsor":
  Mike: Don't touch that dial! You're tuned to the Commercial Channel! All commercials, all the time. (Darkly) An eternity of useless products to rot your skeevy little mind forever.
  Mirror Bob: Aaaahhhhh!!! (immediately flees back into the mirror he came out of)
• Cowardly Lion: Mike can actually be braver than most people give him credit for. Whether it's willingly helping Bob with his plan to stop Hexadecimal from wrecking Mainframe with the system's paint program, staying in Lost Angles to provide her with "therapy" for her after Bob removed her mask, or destroying a shadow monster, getting rid of Bob and Dot's Evil Counterparts and eventually winning the game of A Dungeon Deep, Mike's come through for the heroes more times than you'd think.
• A Day in the Limelight: "Wizards, Warriors, And A Word From Our Sponsor" sees Mike get trapped in a game with the main cast. To their surprise, he actually shows some ingenuity and becomes The Hero for once.
• Disability Immunity: In Enzo The Smart, Enzo attributes how Mike seems completely unaffected by the system-wide stupidity caused by Enzo's messing with the clock speed program to him not being able to get any dumber.
• The Dreaded: Parodied in "Wizards, Warriors, And A Word From Our Sponsor." Bob actually tries hiding, and he Dot, and Enzo scream in terror when Mike approaches them. No virus ever prompted such a reaction from these three.
• Early-Installment Weirdness: In his first appearance, in "The Tiff," his voice sounds filtered like an old radio. It was dropped for all subsequent appearances.
• Floating Limbs: His mouth isn't connected to the rest of his body. He can also detach the upper part of his body from the lower part.
• The Friend Nobody Likes: He annoys the others so much that no one is surprised to learn that his own remote control ran away.
• Hidden Depths: Mike may be a horribly obnoxious idiot, but he's shown to be a surprisingly effective teammate, went with Bob to stop Hexadecimal despite the very like chance it would get both of them killed, stayed with Hex in an attempt to keep her distracted, and helped fight a giant null monster.
• Kent Brockman News: Way too eager for ridiculous dramatics to take seriously as a reporter. But they let him do it anyway.
• Large Ham: "Surprise your friends! Amaze your family! ANNOY PERFECT STRANGERS!!!!!!... it's absolutely nothing." Bob can't turn the volume down either.
• Motor Mouth: Mike talks at a thousand miles a minute when he gets a good head of steam. So don't let him.
• New Job as the Plot Demands: Besides acting as a living TV for Bob and other characters, Mike's done everything from news reporting to hosting documentaries to interviewing celebrities to televangelizing to appearing in commercials.
• No Celebrities Were Harmed: Often speaks in different impressions when doing Shout Outs. His regular voice also appears based on Phil Silvers.
• Out of Focus: For the Darker and Edgier Season 3. Lampshaded in "System Crash."
  Mike: Hey, is there room in this crowded show for a cameo by everyone's favorite talking television?
  Everyone else: NO!
• Phrase Catcher: Everyone else tends to shout MIKE! at him when annoyed.
• Shout-Out: Almost everything Mike says is patterned after some element of popular culture. He's pretty much a living Shout-Out.
• Sinister Minister: Downplayed. While he's brainwashed by Daemon, he takes on the form of a televangelist broadcasting The Word and making catchy music praising Daemon, but unlike her other Sinister Minister Deacon, he never does anything blatantly evil.
• Small Name, Big Ego: He knows Bob, you know!
• Unwitting Instigator of Doom: In "Nullzilla," Mike TV tries to entertain Hexadecimal with a program of a viking opera star hitting a note that shatters glass. This shatters Hexadecimal looking glass, which allows a Web virus to infect her and make her Nullzilla. Said virus also later causes Megabyte to merge with Hex, and the fusion removes what little honor and mercy he had, which eventually leads to the show's Cerebus Syndrome.
• Unwitting Pawn: As part of her larger plan to infect the Net, Daemon arranged for a Web creature to enter Mainframe through Hexadecimal's looking glass. Mike accidentally shattering it with a loud opera show gave Daemon the opportunity she needed.

Cécil

Voiced by: Michael Donovan

Cécil is a stereotypical French waiter at Dot's Diner. He is a video screen with arms and very French-looking facial features, although he has no legs. Instead he movies around on a pole attached to slide tracks in the ceiling. That is until the diner is destroyed and his pole gets attached to a zipboard, allowing him to move more freely. He tends to be rude but is nevertheless loyal to his boss Dot.

He resembles an old Macintosh computer, complete with a rainbow-colored icon.

---

• Character Catchphrase:
  • "Wait at ze bar, wait at ze bar."
  • "I am not a nanny."
  • "That's Ceh-cil!" (After someone pronounces it Cee-cil).
• Camp Straight: Very prim, proper and finicky.
• Deadpan Snarker: He is especially snide towards Bob.
• Jerk with a Heart of Gold: He's a prick, but he's loyal to Dot.
• National Stereotypes: Specifically, French ones. Enzo even calls him the "foreign stereotype comic relief" in "My Two Bobs."
• Plucky Comic Relief: Usually serves as this, despite being a sprite of few smiles. He lights up the mood during the otherwise devastating system crash in End Prog. While others are comforting each other and just watching the chaos, a furious Cécil tries to deal with the drunken pirates.

Turbo

Voiced by: Gary Chalk, Jorge Santos (Latin American Spanish dub, Season Two), Salvador Delgado (Latin American Spanish dub, Season Three)

Turbo is the Prime Guardian, the leader of the Guardian collective operating out of the Super Computer and head of the Guardian Council. Turbo's Keytool is Copland.

---

• Big Good: He's in charge of protecting the Super Computer and borderline systems.
• Defector from Decadence: He was the only guardian to resist Daemon's infection (for a time), looking to find Bob, the only uninfected guardian, to see if he could help.
• Heroic Build: A bit more muscular than Bob.
• I Did What I Had to Do: He was willing, albeit reluctantly, to follow Guardian protocol to destroy Mainframe when a web creature was confirmed to have made its way there. Though he added a few more minutes on the bomb to give Bob time to get rid of it.
• Screw the Rules, I Make Them!: He added the few minutes on the bomb after having the rest of the Guardian Council leave him to be alone with his thoughts.
• This Is Unforgivable!: Bob's philosophy on reprogramming viruses for the good often puts him at odds with his superior, believing Megabyte to be beyond redemption for what his genesis did to Mainframe's Twin City, and Bob's partner, Dixon.
• Unwitting Instigator of Doom: His part in "Trust No One" led to the Web War, and the Viral War immediately after. Both led to Bob getting lost in the Web, as well as Enzo, AndrAIa, and Frisket being forced to game-hop to save themselves, which led Enzo to become Matrix.
  "For what it's worth, I'm sorry."

"The Crimson Binome" and the Saucy Mare Crew

Voiced by: Long John Baldry (Capacitor), Kathleen Barr (Princess Bula), Michael Donovan (Mr. Christopher)

Captain Capacitor (Or, as he likes being called, "The Crimson Binome") is the captain of the Saucy Mare and its crew of pirates. He is a one binome and a fairly honorable man. Originally dealt in piracy, until Dot convinced him that legal business was more profitable (the damage done to his operation by kidnapping Bob, who subsequently escaped helped drive the point home). He later became an ally of Mainframe, especially Matrix, whom he helped search the web for Bob. His crew includes his nerdy accountant Mr. Christopher, and Princess Bula, an Amazonian giant one binome.

---

• Action Girl: Princess Bula is very big and does a lot of fighting.
• Armor-Piercing Question: Knows how to keep the brooding, violent Matrix in line.
• Benevolent Boss: Captain Capacitor is friendly, generous, and jocular with his crew, and frequently rewards and praises them for their successes.
• Cut Lex Luthor a Check: He could make more money as a legitimate merchant than as a pirate. When Dot points this out to him and backs it up with her business savvy, he immediately gives up piracy for honest work.
• Deconstructed Trope: Piracy seemed like a great way to make a quick profit, till Dot pointed out they spend so much on weapons, ammo, damages, etc on every raid that they barely break even after they sell their ill-gotten loot. She offers them a way to make good money transporting goods without spending most of their existing funds just to take it by force.
• Expy: Capacitor and Mr. Christopher are very reminiscent of Captain Hook and Mr. Smee.
• A Friend in Need: Captain Capacitor always comes through for these. He pretty much admits he's helping Matrix get home (and putting up with his horrible behavior in the meantime) out of love for his friend and business partner Dot, and furthermore agrees to chart a dangerous course in the Web to save AndrAIa.
• Brawn Hilda: Princess Bula.
• Fake Aristocrat: Princess Bula isn't a real princess, but no one dares tell her different.
• Good Pays Better: They give up piracy at the end of their debut episode to go into honest business with Dot after she explains how much more money they can make.
• Huge Girl Tiny Guy: The Princess falls in love with Specky, the nerdy one binome working in the Principal Office.
• Large Ham: Capacitor. Again, he's Robotnik after all.
• Pirate Booty: Profit is their main concern.
• The Pirates Who Don't Do Anything: At first averted, but once the Pirates leave piracy for legitimate business, they fall into this trope, never being seen to do anything but act pirate-like.
• No Guy Wants an Amazon: Princess Bula has this effect on most people, although Specky seemed to warm up to her toward the end of Season 3.
• Only in It for the Money: The Saucy Mare crew are pretty much only interested in profit (especially Mr. Christopher), but Captain Capacitor can also be motivated to help A Friend in Need. See Screw the Money, I Have Rules!.
• Screw the Money, I Have Rules!: When Mr. Christopher mentions that they'll return from their voyage through the Web without a cent to their names...
  Captain Capacitor: Aye, lad, perhaps so, but there be other reasons to set sail besides profit!
  Crew: *GASP!*
  Captain Capacitor: ...like repaying a debt to a friend, for one! Sometimes, doin' the right thing, lads, is worth more than all the booty a swab can carry! *turns to Mr. Christopher with a Death Glare* Be I makin' meself clear, lad?
• The Stoic: The 1 Binome who's constantly peeling potatoes, no matter the level of danger surrounding.
• Tuckerization: Capacitor shares his first name with one of the show's co-creators.
• Verbal Tic: Yarrrrr!!
• What Happened to the Mouse?: At the end of Season 3, the crew is in Mainframe and seems poised to further help the Mainframers against Daemon. However, in Season 4, they are never seen doing so and — outside of a cameo — most (including Capacitor himself) never appear. A quick shot of a vid-window in "Daemon Rising" suggests Capacitor at least has been captured, but it is never made clear through dialogue and the whole crew goes unmentioned.
  • Several of them are seen at Dot's wedding though.
• What the Hell, Hero?:
  • Capacitor to Matrix, when Matrix refuses out of hand to release Ray Tracer from prison while breaking out the crew of the Saucy Mare.
  • Does it again after Matrix almost gets everyone on the Saucy Mare killed by steering them through a web storm against Ray's express instructions.

Villains

Megabyte

^{Click here to see Megabyte's appearance post-Season 3.}

Voiced by: Tony Jay, Federico Romano (Latin American Spanish dub)

The Big Bad. A virus that styles himself after an Evil Overlord. He alternatively seeks to take over Mainframe or enter the Super Computer, where he could infect its vast resources to take over the entire Net. He is The Virus, having the ability to infect Binomes and turn them into his Mooks. He is very powerful, so much that only three people would dare face him one-on-one in direct combat: Bob, Matrix, and Hexadecimal.

---

• Actually a Doombot: One of the powers he gains as a Trojan Horse is the ability to create Aliases, which are essentially perfect duplicates of him except full of “empty code”. He uses it to great effect in the final episode of season 4.
• And Now You Must Marry Me: In "My Two Bobs", he disguises himself as Bob and seduces Dot entirely For the Evulz. It works, and they are almost married before Glitch strips the disguise from Megabyte. What makes it even more depraved is that for him, its Brother–Sister Incest, because he and Hex always viewed Welman Matrix as their father after he accidentally created them in the Twin City disaster that split Gigabyte.
• Affably Evil: He's quite evil, but he's quite pleasant and refined, and even spared Bob and Dot's life because Bob saved him in a game. Not to mention the Rock Off mentioned under Pet the Dog. This is most notable during season 1, though as the show progresses, he becomes more and more Faux Affably Evil.
• Arch-Enemy: Not towards Bob, surprisingly, but towards Enzo Matrix beginning in season 3.
• Bad Boss: Megabyte doesn't treat the virals under his command very well. The same goes for Hack and Slash. Physical punishments are the order of the day for failures and everyone is considered expendable to him.
• The Bad Guy Wins: Season 2 ends with him successfully backstabbing Bob and sending him into the Web, while turning on Mainframe during the battle with the Web Creatures allowing him to remove almost any opposition to his take over of the city. Season 4, and by extension the original show, end with him taking over the Principal Office.
• Be Careful What You Wish For: Taunts Matrix into putting down his gun and fighting him with his bare hands "like a real Sprite". Matrix obliges.
• Big Bad: Of Mainframe.
• Big Stupid Doo Doo Head: His usual condescension devolves into this during his Villainous Breakdown at the end of Season 3. As Matrix is clearly winning their battle, Megabyte shifts from smug mockery to childish, barely coherent taunts as he gets increasingly desperate.
• Blunt "Yes": When Enzo calls him out on using Hexadecimal as a power source for his weapon, Megabyte casually cops to it.
  Enzo: You did that to your own sister?!
  Megabyte: Yes, yes, yes. It's rather good, isn't it?
• Body Horror: His time in the Web didn't do his looks any favors, warping Megabyte's once streamlined appearance into a hellish, semi-organic, bestial form.
• Call-Back: The first episode, "Enzo's Delivery Service", has Megabyte call on Enzo's service to deliver a package to Hexadecimal. In season 3, when Enzo has become the only defender of the system, Megabyte once again calls him a "mere delivery boy".
• Card-Carrying Villain: When Enzo reacts with horror to how Megabyte was using Hexadecimal as a weapon, Megabyte responds with pride.
  Enzo: You did that? To your own sister?!
  Megabyte: Yes, yes, yes. It's rather good, isn't it?
• The Chessmaster: His various schemes, especially his spectacular betrayal of Bob & takeover of Mainframe (both times)
• Chronic Backstabbing Disorder: And proud of it. He will always betray anyone who makes a deal with him. Always.
• Cold-Blooded Torture:
  • What he does to Hex in season 3 to force her into being a weapon for him. He has Herr Doktor install a pain collar around her neck, which Megabyte can activate via a control panel attached to his arm.
  • In season 3 he also cuts off Phong's head and tortures it for information.
• Color-Coded for Your Convenience: Everything that serves Megabyte is dark blue, with neon green markings. Even the sprites that bear his infection are dark blue, with neon green markings and green PIDs.
• The Comically Serious: A result of being Surrounded by Idiots.
• Crown-Shaped Head: Sports a badass, fish-looking one at the back of his head.
• Dark Is Evil: Megabyte's color scheme is primarily dark blue, and anything he infects takes on a similar coloring.
• Deadpan Snarker: Makes sarcastic remarks at expense everyone around him. Sometimes Played for Laughs, other times it's done to show what a jerk he is.
• Determinator: Megabyte is a liar, backstabber, but one thing he is not is a quitter. He survives a trip into the web, just like Bob. After that he returns for revenge.
• The Dreaded: He's definitely the one spoken of in the direst tones by the main heroes.
• Easily Detachable Robot Parts: While we never actually see Megabyte do it, his legs come off when he sits on his throne.
• Egopolis: His ultimate plan is to turn Mainframe into "Megaframe."
• Even Evil Has Standards: Even with his goals, there are a couple things Megabyte finds barbaric: 'Mon fighting and reformatting viruses into sprites. Also, at one point, he's about to dissect Frisket and explicitly orders his minions to take Enzo away so he doesn't have to see it; of course, he still twists the knife by refusing to let Enzo say good-bye.
• Evil Brit: He speaks with a British accent and is the Big Bad.
• Evil Is Petty: In addition to his grand machinations, he disguises himself as Bob and almost manages to marry Dot just to screw with her and everybody else.
• Evil Laugh: Uncommon, but spectacular whenever he chooses to do one.
• Evil Overlord: Rules over a section of Mainframe with his own army of infected binomes.
• Evil Plan: It seems like he wants to take over Mainframe but it's actually a stepping stone to reach the Super Computer. Though he had smaller scales ones too.
• Evil Sounds Deep: Very deep, and he wields it well.
• Evil Versus Oblivion:
  • The primary conflict between himself and Hexadecimal. Megabyte wants to rule over Mainframe with an iron fist, while Hex is so intent on burning it to the ground that she doesn't even care if she dies too. Given Megabyte's actions and Hex's obvious insanity, it's a rare case where the "oblivion" side is the more sympathetic of the two.
  • This is why he assists in fighting off Web Creatures in season 2; he can't conquer a deleted system (especially since he'll be deleted along with it). It also presents him with a fantastic opportunity to take out Bob, which goes off without a hitch.
• Faux Affably Evil: From season 2 onwards. While still polite and Wicked Cultured, he's also more vicious and even psychopathic, doing such things as gleefully torturing Hexadecimal and being willing to sacrifice his own minions to get what he wants. And when he gets really angry, he drops the act completely, running on all fours and roaring like a big cat.
• For the Evulz: Primarily shown when he convinces everyone he is the real Bob and very nearly marries Dot because he could.
• Fusion Dance: Forms Gigabyte with Hexadecimal and the Web Creature. When that happens, you're dealing with Apocalypse How.
• Genius Bruiser: He has The Plan to manipulate and the muscles to intimidate.
• Graceful Loser: He's quite calm about his ruse being exposed in "My Two Bobs."
  Megabyte: (nonchalantly) I see my charade is at an end. A pity. We would have made the perfect couple.
• Go-Karting with Bowser: He shows up for Enzo's birthday party in one episode, and not to wreck the place, but to perform an awesome guitar solo and give Enzo the guitar as a present.
• Healing Factor: Has survived numerous injuries which could possibly erase a virus. May be just inhuman durability due to his literally metallic skin.
• Hunting the Most Dangerous Game: Implied at the end of Season 4. He explicitly refers to viruses as “predatory”, and then follows that he’s ready to fulfill his function and bring about “The Hunt”, suggesting his new goal is personally hunting down and killing everyone in Mainframe. Sadly, we never get to see it happen.
• Hypocrite:
  • Rebukes Bob's plan to reprogram him as a Fate Worse than Death. Ignoring the fact that as a Trojan Horse Virus impersonating Bob, he's already been living in harmony with the protagonists for a good long while, and even defending the system from Game Cubes.
  • He almost constantly mocks Enzo's immaturity, and even after Enzo has become Matrix he still mockingly brings up his tendency to childishly insult Megabyte. When Matrix starts beating him in a fight, Megabyte devolves from his usual condescending mannerisms to to similarly childish taunts.
• It Amused Me: When Bob demands to know why he went through with the "My Two Bobs" scheme, he freely admits that he did so for fun, even quoting the trope name word-for-word.
• Irony: He tells Enzo that he is only alive by his own good will early on in season 3. At the end of the season, he's the one only kept alive by Matrix's good will after Matrix defeats him in combat and has him at his mercy.
• Jerkass: Why did he decide to impersonate Bob and nearly marry Dot? Because he's a dick, that's why.
• Large and in Charge: He's huge compared to binomes and extremely large compared to most sprites, though Matrix is almost exactly the same size.
• Large Ham: He has his moments — with a voice like that, how can you not — though he can't quite compete with Hexadecimal.
• Let's Fight Like Gentlemen: Subverted; in Season 3, Megabyte convinces Matrix to throw his gun away and "fight like a real sprite." This gets Megabyte Punched Across the Room— which leaves a dent in Megabyte's armored chest (cue Oh, Crap! expression from Megabyte)— and then tackled through a wall, at which point Megabyte pulls out his Wolverine Claws. Then AndrAIa throws her trident at the two of them for Matrix to use.
• Lightning Bruiser: He can outrun his armored Binome Carriers despite attempts to go full speed, and when he catches up to it he can throw it around like a rag doll.
• Literal Split Personality: He and Hexadecimal were originally one being, Gigabyte.
• Manipulative Bastard: Pretends to be the real Bob and turns Mainframe against him.
• Made of Iron: He can take a lot of hits before he starts to slow down. His skin is even literally metallic.
• More Teeth than the Osmond Family: He has three rows of serrated teeth in his mouth.
• Motive Decay: As of season 4, he's gone from conquest of Mainframe to only caring about revenge. He even lampshades it:
  Megabyte: You're probably looking forward to one of my erudite speeches about me, Megaframe, the new viral dawn, et cetera et cetera. But I'm afraid I'm going to have to disappoint you. There is no grand scheme here. This is about revenge.
  • It later becomes a complete inversion, when he ultimately mentions his function right from the start was just to prey on sprites and destroy everything. It turns out he decayed his motive a long time ago and is finally getting down to business.
• No-Holds-Barred Beatdown: Just because he sounds refined doesn't mean he won't fight like an enraged bear when pressed.
• No-Nonsense Nemesis: The end of his character arc has him returning to Mainframe vowing revenge and serving his viral function. No longer seeking aspirations of "Megaframe" but now dedicating himself to "the hunt".
• Not-So-Harmless Villain: In early episodes, he was typically involved in humorous situations and rarely caused any permanent damage. However, this was largely due to Executive Meddling; after the show left ABC, Megabyte became far more evil and threatening.
• Obviously Evil: He's a hulking brute with a dark coloration, a suave British accent, and a deep voice. Even without all of his various schemes, it's not hard to tell at a glance that Megabyte's the bad guy. It's even more obvious after he returns from he Web, with his new, warped appearance making him look more monstrous than ever.
• Oh, Crap!: After Matrix punches him across the room, he looks down and sees a dent in his chest. It's one of the first times anyone is ever seen as anything close to a direct physical match for him, and his expression is one of utter shock at the idea that Matrix could actually injure him without his Gun.
• Order vs. Chaos: The Order to Hex's Chaos. Megabyte is a dictator bent on domination.
• Out-Gambitted: In "The Medusa Bug" he believes Hexadecimal is keeping a powerful virus from him and steals it from her lair. Turns out she wanted him to do it since she couldn't risk opening it herself.
• Pet the Dog:
  • As awful as a being he is, his rock-off at Enzo's birthday was nice and awesome. He even gave Enzo his guitar as a birthday gift.
  • Played With with Nibbles. Megabyte seems to have some strange affection towards the null, to the point where he'll threaten severe consequences to Hack and Slash if they fail to take care of him, but he'll also crush him in his hand, something that while not able to cause any long-term harm does seem to cause him pain.
• Post-Mortem Comeback: When Bob enters the core to save data and force a system restart, he encountered a program left behind by Megabyte, who was launched into the Web. It's a simulation of Megabyte, which can self-replicate, but all it does it taunt Bob.
• Power Up Full Color Change: Downplayed, as it isn’t quite full, but after returning as a Trojan horse, the green part of his color scheme is replaced by cyan.
• Psychotic Smirk: While most expressions of his beyond contempt range into this territory on an episodic basis, he gives his most terrifying one right before he rockets Bob into the Web.
• Punny Name: Has a huge jaw full of More Teeth than the Osmond Family.
• Schmuck Bait: Subverted. He attempts to bait Matrix into fighting him in hand to hand combat rather than using his gun. When Matrix obliges, he shakes his head with a mocking smile, sure in his own victory- until Matrix punches him across the room and dents his chest, causing Megabyte to realize that was a mistake.
• Sibling Rivalry: He's technically Hexadecimal's brother and is fighting her over rulership of Mainframe. He also considers Welman Matrix his father, therefore his conflict with Dot also can be considered this.
• Slasher Smile: He gives one during his first fight with Bob in the fourth season.
• Sore Loser: "Do you want to see how much I hate to lose?"
• Super-Strength: On par with Hack, Slash, and Frisket; Megabyte has overpowered giant Exoskeletons and thrashed armored tanks barehanded.
• Surrounded by Idiots: Always seems that way. Hack and Slash are the worst of it, but many of the foot soldiers are goofy bumblers (though the Binomes up their game in Season 3). Even Herr Doktor (for all his usefulness) has goofy quirks that contrast with Megabyte's serious demeanor.
• Take Over the City: He'd prefer the Supercomputer, but until he gets access he'll take what he can get.
• Teeth-Clenched Teamwork: Whenever he works with Hexadecimal, due to their conflicting styles and quirks. She's often amused by it all, but he just expresses irritation.
• Took a Level in Jerkass: As of the season 2 finale, he just gets worse and worse, spending the third season as an increasingly sadistic monster who shamelessly taunts his enemies over the suffering he causes them. Upon his return in season 4, he's become so twisted that he'd pose as Bob, win over the real Bob's friends, and convince Dot to marry him, all just to be a dick. He follows this up by whipping Mainframe into a frenzy, seizing control of the Principal Office, and preparing to engage in a sadistic hunt to take revenge on the heroes for defeating him so many times before.
• The Sociopath: All the qualities of a certifiable psychopath: ruthless, sadistic, and a Manipulative Bastard and Chessmaster all rolled into one. He committed lots of atrocities against the Net purely for his own ambitions, and he never showed a pint of remorse about them.
• Surrounded by Idiots: His lackeys are all morons to some degree, barring Herr Doktor. Megabyte frequently gets annoyed with all of them.
• Underestimating Badassery: He taunts Matrix into disposing of his gun and fighting hand-to-hand... and realizes what a bad move that was when Matrix punches him across the room.
• Unwitting Pawn: Hexadecimal lures him into stealing, then opening a virus of hers that turns everything into stone.
• Vile Villain, Laughable Lackey: He's the vile villain to his laughable lackeys Hack and Slash.
• Villains Want Mercy: After Matrix defeats him in season 3 and has him pinned down, facing the business end of AndrAIa's trident, Megabyte, while he doesn't outright beg, wheezes that Matrix can't kill him, as it would go against everything he stands for. Matrix ultimately decides to spare Megabyte on the grounds that he's Not Worth Killing.
• The Virus: He has the power to turn a machine a deep steel blue (like himself) after which he can manipulate it at will. He turns things around quite handily this way in "Infected."
• Villain Has a Point: When threatening Enzo in his below mentioned You Wouldn't Like Me When I'm Angry! moment he rightly points out that if he wanted to he could kill him on the spot.
• Villainous Breakdown: When Matrix is able to take him on in hand-to-hand combat at the climax of Season 3 and is winning, Megabyte completely loses it and for once drops his sophisticated, eloquent attitude in favor of snarling rage.
  Megabyte: You are becoming an ANNOYANCE, BOY!
  Matrix: Trust me, it gets worse!
  Megabyte: IT DOES NOT!
• Voluntary Shapeshifter: At the end of season 4, having become a Trojan Horse virus.
• We Can Rule Together: He makes such a pitch to Bob in the first episode.
  Megabyte: You don't have to fight me, Bob. Think about it. We could be a great team.
  Bob: I'd rather be erased.
  Megabyte: Your choice. [extends claws]
• Wicked Cultured: The guy is, again, voiced by Tony Jay. What did you expect out of him?
• Wolverine Claws: He sports two mean sets of these, one from his fingers and one from his knuckles.
• Would Hurt a Child: In the first arc of Season 3, he says Enzo is more useful to him still processing than deleted, but he quickly adds "for the moment." Not to mention him being perfectly fine with letting Enzo fry in the Core, and doesn't hesitate to choke him or let him get into dangerous situation.
• Xanatos Speed Chess: One such example: in "The Great Brain Robbery" from season 1, he's aghast to find that his plan to shrink down Mouse, Hack & Slash to get into Bob's brain (so he can have access to the Supercomputer) has gone awry when they wind up in Enzo's brain instead. But once he realizes Enzo was brought into the Principal Office, past all the security, he immediately initiates plan B: getting into Mainframe's central system core.
  Megabyte: It's no Supercomputer, but not a bad catch either.
• You Wouldn't Like Me When I'm Angry!: From "Firewall": Enzo and AndrAIa exit a game and are confronted by Megabyte:
  Megabyte: "I have a message for your sister.
  Enzo: "I am a Guardian! I'm not your messenger!"
  Megabyte: "You are what you have always been: a mere delivery boy. *picks Enzo up by his throat* Do not provoke me further; it is by my will alone that you survive this encounter."

Hack and Slash

Hack is voiced by: Phil Hayes (Seasons 1 and 2), Scott McNeil (Seasons 3 and 4), Alfonso Obregón Inclán (Latin American Spanish dub, Seasons 1 and 2), Carlos Íñigo (Latin American Spanish dub, Season 3)

Slash is voiced by: Gary Chalk, Carlos Del Campo (Latin American Spanish dub)

Megabyte's two bumbling henchmen who often screw up their given tasks. Both are rather fond of Bob despite being his enemy and have aided him on occasion. Not willing to cross the Moral Event Horizon by deleting a binome on Megabyte's orders (because Bob wasn't there to stop them, in their own words) or left for dead, they later join the side of good. Hack, the red one, has a higher-pitched voice (the voice of Rattrap, to be precise) and tends to be rather callous, while Slash, the blue one, has a deeper voice and is more sensitive and kind than Hack.

---

• Bumbling Henchmen Duo: Megabyte's incompetent crooks.
• Butt-Monkey: Initially, though they became less this after joining the good guys.
• Co-Dragons: In the first two seasons, they were both this by default because the rest of Megabyte's army was made up of nameless, interchangeable Binomes. Early on in Season 3, though, Herr Doktor takes The Dragon spot.
• The Ditz: Yeah, uh, if it hasn't already been established yet, they're idiots.
• Divergent Character Evolution: They start off so similar in terms of temperament and quirks that the only difference between them is coloring. Over time, Hack becomes more snarky and the one that's smarter by comparison (and only by comparison), while Slash demonstrates more ethical standards.
• Dumb Muscle: They're not exactly the sharpest tools in the shed, but they can punch someone the size of Gigabyte a significant distance.
• Even Evil Has Standards: In "Game Over," Slash saves Cyrus from deletion and lets him escape.
  Slash: I cannot do this. It is bad.
  Hack: That's the whole idea!
• Harmless Villain: The two of them cannot do anything right. "Game Over" revealed that Slash was always counting on Bob stopping them from doing anything really bad.
• Heel–Face Turn: In season 3, they become good, though they weren't really bad in the first place.
• Ineffectual Sympathetic Villains: Prior to their Heel–Face Turn.
• Jet Pack: This makes them slightly more useful.
• Made of Plasticine: Quite often, usually for comedic effect.
  • Usually. Eventually Hexadecimal damages them to a point where they could no longer be fully repaired. Until the reboot.
• Minion with an F in Evil: Especially apparent come season 3 when their conscience catches up with them. They were perfectly happy doing Megabyte's bidding because they knew they wouldn't do any real harm because they knew Bob would always show up in the nick of time to thwart them before they did anything bad. With Bob gone and Megabyte winning, they couldn't stomach what they were being made to do.
  Hack: Now you've done it... Megabyte is gonna be mad!
  Slash: Ah, what's new? I miss Bob.
  Hack: What? You crazy?
  Slash: Bob always stopped us before we could do anything really bad... Now, nobody does...
• Motor Mouth: Both of them talk very quickly, and they often overlap each other.
• Multi-Armed and Dangerous: Both have numerous hidden extra weapons and arms, but usually to little effect.
  • This is parodied when Matrix and AndrAIa are infected by Daemon. Hack holds AndrAIa back with both hands while Enzo talks to Matrix, and when AndrAIa is about to shout at Matrix, Hack pops a third arm out of nowhere to cover her mouth.
• Redemption Promotion: They show a notable increase in competence after switching to the heroes' side. They were still dim and bickered, but were less likely to screw up their part in any plans.
• Red Oni, Blue Oni: Hack is, quite literally, the red to Slash's blue.
• Super-Strength: Slash once punched Gigabyte clear across the energy sea back into Mainframe.
• Punch-Clock Villains: It's implied early on that Hack and Slash are not really evil, they're just working for Megabyte. After Megabyte launches Bob into the Web at the end of Season 2, Slash laments that there is no one around to stop them.
  Slash: I miss Bob, [he] always stopped us before we could do anything really bad, now nobody does...
• Those Two Guys: They are comic relief characters who are seldom apart.
• Token Good Teammate: They quickly become this. They are not mean-spirited, generally spooked by Megabyte's eviler acts, and even like Bob.
• Undying Loyalty: Their most redeeming value. Whether working for Megabyte, Phong, or Dot, they are consistently loyal.
• Vitriolic Best Buds: Hack and Slash bicker constantly. The sad thing is, that's just one reason they aren't so great at being henchmen.
• You Have Outlived Your Usefulness: By "Game Over", Megabyte has "grown weary of their incompetence", and that's before they failed to destroy the traitor Cyrus as ordered. So he had them take position in the next attack, and left them for dead.

Herr Doktor and Bunnyfoot

Voiced By: Garry Chalk (Herr Doktor) and Ian James Corlett (Bunnyfoot)

Bunnyfoot (left) and Herr Doktor (right)

A pair of Viral (infected) Binomes who serve Megabyte. Both are 1-shaped Binomes, with Herr Doktor being a Mad Scientist and Bunnyfoot his Igor.

---

• Ascended Extra: In his debut, Herr Doktor had no dialogue or name, and was completely interchangeable with Megabyte's other Viral scientist.
• Body Horror: Bunnyfoot's three body segments are all mixed-up, his left arm protrudes from a tumorous mass, and his feet are made from a brick and a bunny slipper (hence the name).
• Creepy Long Fingers: Herr Doktor's fingers look creepy enough on their own, but the fact that he is literally the only Binome with fingers makes them stand out more, as all of the others just have pincer-like Fingerless Hands.
• A Day in the Limelight: Herr Doktor and Mike the TV are the protagonists of the second ReBoot IMAX ride, Journey Into Chaos.
• The Dragon: Herr Doktor, nominally; while he is Megabyte's second-in-command and the last obstacle that Matrix faces before Megabyte, he puts up little resistance (just threatening Phong) before running away with Bunnyfoot.
• Enemy Mine: Bob ropes Herr Doktor into helping him return the Core's energy to the Principal Office in order to save Mainframe in "Bad Bob."
• Evil Feels Good: The two remained loyal to Megabyte even after being cured of his infection by the User.
• Fingore: Herr Doktor's fingers get mangled thrice, leading to cries of, "Ach! Mein digits!"
• Flat Character: Bunnyfoot, a mute who exists only to look off-putting and perform menial tasks for Herr Doktor and Megabyte. The only bit of characterization that he ever got was it being implied that he was the one who was responsible for Hexadecimal's new Dressed Like a Dominatrix look in "Between a Raccoon and a Hard Place."
• Forced Transformation: They were turned into cookies (with screaming faces) by Hexadecimal, but were restored when the system was restarted by the User.
• Frankenstein's Monster: Bunnyfoot looks like he was cobbled together from assorted Binome parts, as well as random junk.
• Hate Sink: Herr Doktor stands out as the most despicable of Megabyte's minions, clearly enjoying trying to vivisect Frisket, helping launch Bob into the Web, and torturing both Hexadecimal and Phong; when Megabyte gives him free reign to do whatever he wants to the latter, Herr Doktor even gleefully thanks him while bragging about how he is going to make Phong "squeal." And "My Two Bobs" reveals that none of this is even due to Megabyte's infection and influence, Herr Doktor is just a sicko who actually likes working for Megabyte.
• Herr Doktor: Herr Doktor, of course. He even refers to Megabyte as "Mein Fuhrer."
• The Igor: While Bunnyfoot is visually inspired by the Frankenstein's Monster, his actual role is this, the weirdo assistant to a Mad Scientist.
• Mad Scientist: Many of Megabyte's gizmos and weapons were built by Herr Doktor, who also verges on Mad Doctor, given what he did to both Hexadecimal and Phong.
• Non-Action Guy: While Herr Doktor did try to help recapture Enzo and Frisket in his debut, it is clear that he and Bunnyfoot are not cut out for combat at all, as they never participated in it and simply ran away (after making an idle threat) when confronted by Matrix.
• Number Two: Herr Doktor becomes this for Megabyte in Season 3. He even gets to ride in Megabyte's Flying Car.
• The Remnant: The two survived Megabyte's downfall, but were eventually located and dealt with by Hexadecimal. After the system restart, they joined a group of likeminded "Neo-Virals" led by Lieutenant Chauncey.
• Torture Technician: Megabyte places the two of them in charge of extracting information from Phong.
• Undying Loyalty: Megabyte, in a rare display, actually expresses gratitude to Herr Doktor for "keeping the faith" when he returns to Mainframe in "My Two Bobs."
• Satellite Character: Bunnyfoot is never shown apart from Herr Doktor.
• The Speechless: Bunnyfoot never speaks, he just makes odd noises, though he is capable of an Evil Laugh.
• Still Wearing the Old Colors: While the other Neo-Virals donned replicas of their old uniforms, Herr Doktor and Bunnyfoot took it a step further by somehow cosmetically altering themselves to look like they were still infected by Megabyte.
• Villains Out Shopping: Megabyte is surprisingly lenient towards Herr Doktor, who has been shown doing things like playing Solitaire, eating a sandwich, and watching TV while working on projects for Megabyte.
• Yes-Man: There are two instances in "Megaframe" where Megabyte, after saying something that he feels is witty, looks expectantly at Herr Doktor, who, after a pause, starts awkwardly laughing and heaping praise on Megabyte.

Hexadecimal

^{Click here to see Hex in Daemon Rising}

Voiced by: Shirley Millner, Nancy McKenzie (Latin American Spanish dub)

A benign virus who lives in the ruins of Mainframe's former twin city, now known as Lost Angles. Essentially chaos incarnate, using the title of The Queen of Chaos, with unpredictable mood swings and a flair for art and drama. Starts out rather villainous, but mellows out under Bob's influence. Hexadecimal is powerful. REALLY powerful. As in she can single-handedly massacre Megabyte's entire forces on her own without breaking a sweat, and Megabyte knows better than to engage her in a straight-on fight.

---

• All-Powerful Bystander: She's able to do things that Megabyte strives for the entire series, such as invading the Principal Office or finding the Supercomputer on just her whim. In her own words, while Megabyte got the smarts and crafty intellect from the fission into two viruses, she got the raw power and destructive lion's share of viral power, but not the sanity to make proper use of it.
• Anti-Hero: After Bob thoroughly heals her damaged face (and her insanity), she ends up becoming an ally. Even then, she only contributes to the war effort against Daemon's forces out of her love towards Bob, and not out of the goodness of her heart.
• Attention Whore: Some of her antics are caused because she's not getting enough attention- Such as in Painted Windows, where she hacks into Mainframe's Paint tool simply to get attention towards her art. When Bob and Mike claim to want to interview her, she is genuinely flattered and goes along with it.
• Ax-Crazy: The Queen of Chaos has several screws loose.
• The Bad Guy Wins: In the "Medusa Bug" no one is able to stop her. However, she ends up reversing the effects of her victory after Bob points out to her that there will never be chaos again if the entirety of Mainframe is dead.
• The Beastmaster: She can control nulls. This is the only ability she keeps after she turns into a sprite.
• Because You Were Nice to Me: She's always had a thing for Bob, but her insanity would get the best of her. After he repaired her mask to emulate a real face, she felt whole for the first time, gaining a sense of perspective. Hex is still joyfully mad, but Bob is now more important to her than ever.
• Berserk Button: Unless she is the one doing this, harm Bob, and she'll make you suffer. Just ask Daemon.
• Betty and Veronica: She's the Veronica to Dot's Betty when it comes to the Love Triangle between her, Bob, and Dot.
• Beware the Silly Ones: As delightfully hammy as Hex is in her antics and mood swings, she still poses an obvious, viable threat when she wants to.
• The Blank: She has a series of masks that she quickly swaps out behind her hand to change expressions. Her real "face" is not shown until halfway through the second season, when Bob removes her mask and reveals that there's absolutely nothing beneath. This also happens in the PlayStation game.
• Brilliant, but Lazy: Hexadecimal has enough power to pretty much destroy a firewall or access the Supercomputer at will, but she's more interested in staying in Mainframe to fight Megabyte and cause chaos for the people of the city.
• Bullying a Dragon: Herr Doktor and his assistant learn the hard way they shouldn't have imprisoned Hex when she turns them into cookies and offers them to the rest of the cast.
• Chaotic Evil: Per Word of God. She even calls herself the Queen of Chaos!
• Chaotic Stupid: Deconstructed. Hexadecimal is much less often a villain than Megabyte is and her antics usually come about due to boredom. She is only a real threat due to her vast Reality Warper powers and is usually defeated by Talking the Monster to Death or simply because she gets bored with whatever scheme she has in progress. Bob treats her much more kindly than Megabyte, even leaving Mike the TV with her as her companion when she is left particularly broken after a fight. It is later shown that as the result of being a Literal Split Personality she couldn't be sane until Bob repaired her, and she acted much less completely random after that point, gaining proper goals in life and even becoming a healed Sprite for a while.
• Child Eater: Played for laughs; she jokes that she loves children but could never eat a whole one.
• Cloud Cuckoolander: After becoming a Sprite, she mellows out and begins to act less Axe-Crazy and more like this.
• Crown-Shaped Head: Fitting to her title of the Queen of Chaos, the back of her head has extensions that fan out like a crown.
• Cruel and Unusual Death:
  • She gives one to Bob and Dot in a Bad Ending in the Playstation game, where she stuffs them after Bob rejects her love.
  • She turns Herr Doktor and his assistant into cookies. Fortunately for them, they're restored when the system is rebooted.
• Dark Action Girl: Easily one of the most physically powerful characters, well above Megabyte's level. If her insanity didn't hold her back, she'd be a cataclysmic threat rather than a capricious nuisance. When she joins with Megabyte and forms Gigabyte, we see what that power coupled with a sharp and sane mind can actually accomplish.
• Dating Catwoman: In the beginning, Bob and Hexadecimal have a Friendly Enemy-dynamic with the occasional flirting, though that isn't to say that Hexadecimal would not try to do away with him if he was ever in her way. Later she holds him hostage, alternating between enjoying her "date" with him and threatening to kill him. After Bob heals her face (and by extension her mind), she becomes much more interested in pursuing something with him, even going so far as to help him fight off Daemon's invading hordes because he asked her to.
• Deadpan Snarker: She sometimes does this, such as when Megabyte realized she'd tricked him into stealing her Medusa Bug:
  Megabyte: You! All this time! All your secrecy! My whole operation!
  Hex: Yes? Yes?
  Megabyte: A trap!
  Hex: Now I suppose you'll want thanks for all your hard work!
• Distracted by the Sexy: In The Medusa Bug she has a moment of being distracted by Bob's rear end while watching him through her mirror:
  Hex: No! Noo! (Her mirror focuses on his rear) Yes...
• Dressed Like a Dominatrix: As of her redesign in season 3 she is dressed like one. While it starts as Go-Go Enslavement, Hex likes the outfit and keeps it, even when she is healed into a Sprite.
• Drives Like Crazy: In Daemon Rising she learns to drive and is very fast when she drives.
• Even Evil Has Standards: When your attitude is bad enough to disgust the Queen of Chaos, it's time to take a good look at your code.
• Evil Laugh: Often, although it tends to lean towards Laughing Mad on more than one occasion (especially during season 3, in which she becomes even more insane than before).
• Evil Versus Oblivion: The Oblivion to Megabyte's evil. A rare instance where the Oblivion side is more sympathetic than the Evil, seeing as Hex is clearly not sane. When she fights Daemon, she becomes the Evil to Daemon's Oblivion.
• Expressive Mask: Averted, mostly. Her face is utterly static, and to change expression, she changes masks, though this happens instantly and generally happens any time her face is obscured from the viewer. Played straight once she gets defragmented — her mask becomes a fully expressive face.
• Expy: Seems similar to Harley Quinn or even a straight up female The Joker, as she's completely insane her whole goal in life is to cause as much mayhem as possible, and her reason is typically no more complicated than "I was bored."
• Fad Super: Her different looks over the course of the series have shades of this. Her original form comes off as a sort of evil East Village Bohemian who really played up the Mad Artist angle, whereas her second "Red Queen" costume has more of a goth/emo/BDSM vibe, which was just starting to become more mainstream around the time it debuted. Her "White Queen" Sprite form is less influenced by real fashion as it is by fantasy art, but by the time that rolled around fantasy was starting to become more mainstream, too.
• Femme Fatalons: She has razor-sharp claws.
• Flying Brick: She has those powers, as well as numerous others.
• Foil: To her brother, Megabyte. Both viruses, Hex is the chaos to Megabyte's order. In the end, their character developments take them in different directions. Hex saves the net and Mainframe having learned to be a sprite and in love. Megabyte embraces his viral being and makes his final stand an act of revenge against Mainframe.
• For the Evulz: Hexadecimal's main goal in life is just to have fun. She enjoys the chaos that comes from her constantly fighting with Megabyte and her giving Bob and the other Mainframers fits.
• Fusion Dance: Forms Gigabyte with Megabyte while infected by a Web Creature. When that happens, you're dealing with Apocalypse How.
• Gallows Humor: Has a habit of it. In particular, she jokes about loving children... But not being able to eat a whole one. Given her great power, the jokes don't always register to others as jokes.
• Glowing Eyes of Doom: Her eyes are always like this except when she's a sprite. Usually green, but tend to turn red when she's angry or becomes unhinged. They have also been yellow, orange and blue on rare occasions.
• Go-Go Enslavement: In season three. However, she likes the outfit and keeps it even after breaking free.
• Good Costume Switch: After becoming a Sprite, her outfit changes from one with a red and black colour scheme to one of white and gold.
• Good Colors, Evil Colors: Her usual color scheme is black and red. When she is purified into a Sprite, her color scheme becomes white and gold instead.
• Happy Harlequin Hat: Hex' crown is a stylized, more regal version of this, in keeping with her Monster Clown aesthetic
• Heel–Face Turn: By the end of season 3, much to Phong's discomfort.
• Heroic Sacrifice: In order to take down Daemon in season 4 and rid the Mainframe of her suicide Virus, she sacrificed herself because that would mean Bob still gets to live.
• Holy Halo: In season 4 after being healed into a Sprite, her crown-shaped head becomes one.
• Insane Equals Violent: She's completely psycho and has some very violent tendencies.
• I Want My Beloved to Be Happy: When making her sacrifice she tells Bob and Dot to be happy together.
• Large Ham: Even static faces don't keep her from chewing scenery to bits.
• Light Is Good: When she does her Good Costume Switch, she gains a white and gold color scheme.
• Literal Split Personality: She and Megabyte started life as one being, Gigabyte.
• Love Redeems: For Bob, who despite all her madness, she never stopped having feelings for. It's what gives her incentive for her Heroic Sacrifice.
• Mad Artist: Hexadecimal is a literal example when she hijacks Mainframe's paint program and turns the city into a surreal nightmare with her bizarre art, which is full of Shout Outs to real-world artists.
• Mad God: Hex is a Physical God for all intents and purposes, and her Reality Warper abilities (particularly when she gains access to the paint program) place her firmly in this category.
• Magic Mirror: Hex possesses a mirror that she uses to view the outside world and communicate with Scuzzy. It's actually attached to the Web, and when it's accidentally shattered an Eldritch Abomination uses it to get inside Mainframe.
• Mask of Sanity: Inverted. Hexadecimal really is crazy, but she can also be lucid and businesslike when she wants to be. In "The Medusa Bug", she cleverly tricks Megabyte into stealing the title artifact so he'll destroy himself. In "Infected", she demands control of half of Mainframe once Megabyte takes over, and makes it clear she'll be paying close attention to what Megabyte is doing.
• Mask Power: Inverted; according to "Painted Windows," her mask actually keeps her transfinite power in check so she doesn't overload, making it a Power Limiter.
• Milking the Giant Cow: Hexadecimal often gestures wildly while hamming it up.
• Monster Clown: Downplayed in that she's pure chaos rather than pure evil, but her White Mask of Doom (with red lips and exaggerated eyes), Mad Artist and Cloud Cuckoolander tendencies give off this vibe.
• Mood-Swinger:
  Hex: Ohhh, Bob. I don't know if I should talk to you or kill you!
• Morality Chain: Bob is this for her.
  • Enzo also proves to be this before her Heroic Sacrifice.
• My God, What Have I Done?: Reverses the Medusa bug when she realizes that with everything in eternal, unchanging stone, Mainframe was as unchaotic as it could get.
• Nightmare Face: Mostly because she doesn't have one under her masks. However, one of her masks is also downright horrifying, with razor sharp teeth in an Ax-Crazy smile.
• Nightmare Fuel Station Attendant: Even when she's not actively Ax-Crazy, she still acts pretty creepy.
• No-Sell: In her viral form, she's immune to Daemon's infection. She is also usually immune to antivirus programs, though this immunity can fade if she expends too much power.
• No Face Under the Mask: Without the mask, her head is blank.
• Odd Friendship: She becomes the younger Enzo's closest friend in Daemon Rising.
• Omnicidal Maniac: In "To Mend and Defend," she is perfectly willing to destroy the Principal Office — knowing full well it would destroy the entire system, including herself.
  "Never mind. It will be glorious."
• The Only One Allowed to Defeat You: Saves Bob and Mike from Scuzzy in Painted Windows, reminding her pet that the Guardian "belongs to her."
• O.O.C. Is Serious Business: In the episode Gigabyte, her power has been greatly reduced and she is left weakly begging Bob to save her from Megabyte corrupted by the web virus. He fails.
• Order vs. Chaos: The Chaos to Megabyte's Order. A Reality Warper who does everything and anything on a whim.
• Pet the Dog: Even Hexadecimal has her own, brief moments:
  • As she is talking to Megabyte via vid window in "Infected", she is shown having Scuzzy on her lap and petting him.
  • Letting Bob (who she kidnapped shortly after his return) go after he fixes her mask.
  • Even after reverting back to her former, psychopathic self in "Sacrifice", Hex says a quick goodbye to a distraught little Enzo before her Heroic Sacrifice where they share an inside joke between them and Hex gives Enzo a gift on his icon, which turned out to be allowing the nullified Welman Matrix to be able to be aware and properly communicate.
• Properly Paranoid: She agrees to help Megabyte on a couple occasions, but she always keeps an eye on him. She's crazy, not stupid.
• Psychopathic Womanchild: Especially in the first two seasons. Considering she has no ulterior motives with her unlimited powers other than to simply cause chaos and never considers how her schemes could backfire (i.e. the Medusa Bug), her behavior is similar to that of an unruly child who acts out when they're bored and want attention. This is driven home in Painted Windows when she crows about finally getting the recognition she deserves for her artistic talents.
• Red Eyes, Take Warning: Her eyes usually turn red whenever she's angered or unhinged.
• Red Oni, Blue Oni: In Season 1 and 2, she was the red to Megabyte's blue. After her Heel–Face Turn in the Season 3 finale, she became the red to Dot's blue.
• Right-Hand Cat: Scuzzy is essentially her pet cat, and he is often shown on her lap as she schemes.
• Sanity Has Advantages: Whenever Hexadecimal became the Monster of the Week, the heroes had little to no chance of overpowering her or beating her into submission. However, most of the time the havoc she causes is For the Lulz and she could be tricked into giving up, like when Bob has her undo her Medusa by pointing out how boring everything would be if everyone was frozen as statues.
• Sanity Slippage: She was insane to begin with, but her horrific injury at the beginning of Season 3 and subsequent torture at the hands of Megabyte only serve to make her even more unhinged.
• Sanity Strengthening: After Bob (having merged with Glitch) uses his new powers to heal the crack in her mask, he ends up taking it a step further and making it a moving, functional face, as well as making her completely sane.
• Schmuck Bait: In The Medusa Bug she deliberately sets up noticeable defenses around the titualar bug to lure Megabyte into stealing it and releasing it onto Mainframe.
• Sexy Villains, Chaste Heroes: Enforced. The writers said they were only allowed to make an evil character sexy, so they went all out on Hexadecimal, giving her a sexy sashaying walk, defined breasts (unlike Dot's uniboob), and having her openly show interest in seducing Bob.
• Sibling Rivalry:
  • With Megabyte. They don't get along and it is revealed that they are brother and sister. Hex even explains their attempts at killing each other with the words.
  • During Daemon Rising, Hex adopts Dot as a sort of sibling due to Wellman Matrix having unintentionally created her. This doesn't at all stop her from pursuing Bob, though she at least asks Dot whether she was interested first (which Dot denied in He Is Not My Boyfriend style).
• Sixth Ranger: After Bob defragments her, she joins the heroes.
• Slasher Smile: Her "Homicidal Glee"◊ mask is this, the source of many childhood nightmares.
  • Exaggerated when infected by the Web Creature.
• Smooch of Victory: Invoked and gender flipped in Daemon Rising. Once Hex deals with the Guardian invasion, she asks for a kiss as her reward. Bob goes in for a chaste one on the cheek, only for Hex to dip him and promptly make out with him.
• Stalker with a Crush: Occasionally acts this way towards Bob.
• Story-Breaker Power: Hex is virtually invincible. The only reason she doesn't take over Mainframe herself is because she doesn't feel like it. After she makes a Heel–Face Turn, she's so powerful that she would render Matrix, Bob and the rest of the cast useless. Hex was then depowered in season 4 so Daemon could still be menacing, though she is temporarily repowered for a fight against Daemon and actually proves a match for the otherwise invincible super virus. She was ultimately killed so a returning Megabyte could become an even bigger threat.
• Stripperiffic: Her default outfit consists of essentially bondage gear starting from season 3. Even when she gets a Good Costume Switch she keeps her corset, garter belts, and stiletto heels.
• Supermodel Strut: She walks in a deliberate seductive strut that has her hips swaying, all to better illustrate her arrogance and desire for attention.
• Talking the Monster to Death: Since Hex is so powerful she often has to be talked out of her plans, such as in The Medusa Bug:
  Bob: Peace and silence forever.
• Taken for Granite: In The Medusa Bug she keeps around a virus that causes this effect.
• Telekinesis: Enough to toss Bob around like a rag doll if she so chooses.
• Too Kinky to Torture: Discussed by Megabyte and Herr Doctor when they have an explosive leash on her. Herr Doctor warns Megabyte it's a miracle they kept her as long as they have, and suggests she might only be playing along because she enjoys being tied up.
• Tsundere: Towards Bob. The quote above under Mood-Swinger is a prime example, for most of the time Hex is unsure if she loves him or wants to kill him.
• Victory Is Boring: There was one time where her Evil Plan actually worked. She won. There was nothing Bob or anyone could do about it. "Peace and silence forever" as Bob put it. She had a panic attack and reversed the damage. Though it was less "Victory Is Boring" and more "That particular victory would be boring", because with everything in eternal, unchanging stone, she was now in a stagnant, predictable, orderly world, which as a self-described Queen of Chaos, was anathema to her.
• Villainesses Want Heroes: She's loved Bob pretty much from the beginning. As she says, she enjoys the chaos he brings into her life. She'll still try to delete him if he wrecks one of her plans.
• Violently Protective Girlfriend: As of Season 4, Hex's motivation boils down to "save Bob at all costs", including returning to her viral, insane self without hesitation and performing a Heroic Sacrifice in order to keep him alive.
• Virtual-Reality Warper: In Painted Windows when she gets control of the paint tool.
• White Mask of Doom: Her Power Limiter mask, which shows what emotion she's currently feeling and swaps out constantly.
• Wicked Witch: While not in name, she lives in a lair, has a catlike Familiar, and has a magical mirror. A cut episode was going to have her reboot into a witch in a Game. In Web World Wars, she hears Mouse call her a "witch" and is flattered that Mouse said something so nice.
• Wild Card: Hexadecimal is usually on her own, with he objective of sowing chaos, but she will sometimes make an alliance with her brother Megabyte, though these never last. On a few occasions she even helps the good guys, when it suits her.
• With Great Power Comes Great Insanity: Though she retains her powers after having her head unscrambled, leading her to do things such as teleport an entire invading army out of the city because Bob asked her nicely.
  • When she gets depowered in Season 4 though, she mellows out even more. And when changed back, even more powerful than before, she goes right back to being crazy.
  • Hex's madness may in fact be a subversion, believe it or not. Her fusing with Megabyte into Gigabyte implies that she could be a lot more destructive if she wanted to, but she finds fighting Megabyte and causing chaos in Mainframe to be a lot more fun. Gigabyte shows what happens when a No-Nonsense Nemesis gets ahold of that kind of power.
• Worf Had the Flu: Is unable to fend off a Web-infected Megabyte in Gigabyte due to having much of her power drained in the previous episode, Nullzilla.
• World-Healing Wave: She does this twice:
  • In Medusa Bug, she cast one to undo the effects of the title Artifact of Doom on Mainframe when Bob pointed out she'd made it permanently stable and unchanging.
  • In Daemon Rising, she downloads the cure for Daemon's infection into her own code. She then fragments herself to spread her code across the entire Net, repairing the damage Daemon caused.
• Yandere: As she softens towards Bob she becomes sweeter towards him, though she's still dangerous to anyone else around. Especially towards anyone trying to hurt Bob.

Gigabyte

^{Click here to see Gigabyte's original form.}

Voiced by: Blu Mankuma

Gigabyte is the combined form of Megabyte and Hexadecimal forced together by the Web creature. When he first appeared, his only stated goal was to absorb energy and reach his full potential.

---

• Big "NO!": The defeat he suffers in his eponymous episode leads him to make one of these.
• Brought Down to Badass: Retroactively it's revealed he was this when first seen thanks to Hexadecimal's energy being drained. He could drain energy and had Megabyte's super strength, but lacked Hexadecimal's powers. But his Energy Absorption still made him a threat to the entire system and he was indestructible to boot.
• Character Catchphrase: "I am become Gigabyte, destroyer of systems!"
• Crown-Shaped Head: Averted. The most Gigabyte has is a small crest on his head, which adds to his no-nonsense attitude. Could be subverted though, if you consider how intricately detailed his armour is.
• Energy Absorption: In his first appearance, he's unable to use Hexadecimal's Reality Warper powers, and goes about stealing the energy from anything he can get his claws on to unlock his full potential.
• Evil Sounds Deep: Gigabyte's voice is just as deep and menacing as Megabyte's, with his lack of Megabyte's affected charm making him, if possible, even more threatening.
• Fusion Dance: Between Megabyte and Hexadecimal. It's later revealed that he was the original.
• Generic Doomsday Villain: Gigabyte's limited screen time means there is not much to him character wise. He is a virus out to gain power and then use it for some evil purpose because he is a virus and that is what he does.
• Godzilla Threshold: Gigabyte is dangerous enough for Bob to broadcast an alert across the entire Net to warn his fellow Guardians about the super virus and call for help.
• Greater-Scope Villain: As Megabyte and Hexadecimal split off from him, he's indirectly responsible for most events of the series, save Daemon, and is actually the reason Bob came to Mainframe in the first place.
• The Juggernaut: Gigabyte is nigh-on invulnerable to everything, and this is in his weakened state.
• Knight of Cerebus: Lacking Hex's lunacy or Megabyte's charm, Gigabyte is played as an absolutely terrifying, dire threat, a prelude to the Darker and Edgier tone the series would fall into after his appearance.
• Near-Villain Victory: He comes this close to claiming the energy in Mainframe's core.
• No-Nonsense Nemesis: Gigabyte doesn't have Hex's madness nor Megabyte's ego or greed. He sets himself to a goal and sticks with it. When Bob sends Glitch, a considerable source of power, away, in an effort to keep it from Gigabyte, the virus simply remarked that taking the energy from two Sprites would do just as well.
• Obviously Evil: When Bob first sees him after his Fusion Dance, he suggests that he might be a benign virus. Enzo sarcastically replies that "you can tell that just by looking at him!"
• Omnicidal Maniac: He refers to himself as the “destroyer of systems”, and it’s clear that he lacks any ambition outside of using his vast powers to destroy. After all, it’s what he’s programmed for.
• The Right Hand of Doom: Gigabyte's right hand is a grizzly three digit claw with long yellow nails. This claw is used to drain energy from his victims.Notably, Killabyte gains this claw immediately after being upgraded but before fully becoming Gigabyte.
• Power Copying: Draining energy from Hack gave him Hack's flight ability. This nearly allowed him to drain the energy of the Principal Office's shields since he was simply able to walk right up to them.
• Shout-Out: His above quote is a modified line from Bhagavad Gita.
  "Now I am become Death, the destroyer of worlds."
• SI Prefix Name: Gigabyte is the combined form of Megabyte and Hexadecimal.
• Tempting Fate: Proclaims he is the destroyer of all systems, yet unwittingly is ripped apart from the destruction of the Twin City before he has a chance to wreak havoc on the Net.
• Top-Heavy Guy: Has a very bulky upper body.
• Truly Single Parent: He is the sole parent of both Megabyte and Hexadecimal since they are his fractured form.
• White Mask of Doom: His face is white, an allusion to Hexadecimal.
• Worf Had the Flu: Phong and Bob note that Gigabyte is lacking enough energy to use Hexadecimal's higher-level powers, probably because Hex herself was drained of energy by the nulls before her Fusion Dance with Megabyte. He spends all his time trying to gain enough energy to use Hex's powers, and even in his weakened state the heroes have to take drastic actions to beat him. If Gigabyte had been at full power when he fused, the heroes likely wouldn't have stood a chance.

Scuzzy

Scuzzy is Hexadecimal's familiar. He is a small, cat-like creature who lives with his mistress in her lair, and serves as her pet and spy. He has a domed view screen on top of his head that can record anything he has witnessed and is small enough to sneak into any area undetected (even Silicon Tor). He is very cunning, sly, and extremely loyal to Hex — although he isn't ignorant of the fact that she's crazy.

---

• Attack of the 50-Foot Whatever: In "Painted Windows", Hex uses Mainframe's paint program to greatly increase his size.
• Cats Are Mean: It looks like a robotic cat.
• More Teeth than the Osmond Family: Shows a lot of fangs whenever it opens its mouth.
• Out of Focus: He seems to completely disappear after "Game Over", until he appears as the bouncing ball during the musical number of the Season 3 finale. He also doesn't appear in Season 4 at all.
• Punny Name: Anyone ever heard of a SCSI (pronounced "scuzzy") interface?
• Ridiculously Cute Critter: Scuzzy is small and kind of adorable.
• Right-Hand Cat: Scuzzy is Hexadecimal's pet.
• Silent Snarker: He gets a lot of use out of those eyebrows.
• The Speechless: The only noises he makes are little purring-type sounds, and the occasional screech.
• Undying Loyalty: For Hex, even though she's a particularly special kind of crazy.

Daemon

Voiced by: Colombe Demers

Daemon is by far the most powerful virus to ever hit the Net. She's a kind and gentle person when you talk to her, but she can enslave entire systems with a touch, will sacrifice any number of troops to achieve her goals, and is out to crash the entire Net.

---

• Affably Evil: Her personality is no act; she's a truly nice and angelic person who just happens to also want to cause the apocalypse. She even seems genuinely saddened and confused when she sees Mainframe resisting her forces.
  Daemon: Why do they suffer needlessly when the Word is inevitable?
• A God Am I: In contrast to Megabyte, who ran his throng of Viral Binomes like a totalitarian dictatorship, Daemon's organization is more akin to a religious cult. Amusingly, she even gets a (literal) TV Evangelist and a chorus of Faceless Goons singing gospel music about her.
• All-Loving Hero: A terrifying exaggeration. Daemon's appearance and demeanor check most of the boxes of Christian sainthood (most specifically Joan of Arc) and the "unity" her infection brings appears benevolent, if a tad extreme. Unfortunately, her infected followers behave like mindless fanatics, she's willing to sacrifice any number of lives to further her cause, and the final step of her plan is to crash the net to ensure the peace she brings lasts forever. The sheer disconnect between her Purity Sue personality and hideous actions make for a deeply unsettling villain.
• Anti-Villain: She wishes to spread her influence so that she can unite the entire Net. Unfortunately, her idea of unity involves infecting everybody with her fanatical brainwashing abilities and commanding all of them to self-destruct, creating a total system crash in an "All Are Equal in Death" sort of way.
• Apocalypse How: She would have crashed the entire Net. For the people in the series, that would likely be equivalent to Galactic or Universal on the trope's scale of scope.
• Baddie Flattery: She's very polite and considerate, and speaks admirably of the main character's love ... though some things she cannot tolerate.
• Benevolent Boss: Being Affably Evil, not that much fazes her, so when Daecon apologizes for his failures in conquering Mainframe, she easily forgives him. With that said, Daecon eventually finds out that she has her limits and will tolerate failure up to a point.
• Berserk Button: She seems to despise Viruses turned Sprites, given her reaction to Hex. It should be noted, however, that her "berserk" never rises above mild annoyance (though she does trash Hex in the process). It's just weird because otherwise she's never seen to be anything but completely happy and polite, even when ordering her followers to commit suicide or getting shot at.
  • She'll also apparently easily retract her feelings if the "offense" is changed. When Hex becomes her viral, psychopathic old self again and fights Daemon, Daemon says "Why do you wish to stand against me? You are a virus; we should be friends."
• Big Bad: She took over the entire Net at one point.
• Blue-and-Orange Morality: Due to her function, she's unable to feel love or go against her programming, which compels her to infect and destroy all systems. She's otherwise a pleasant and sweet person.
• Compelling Voice: Sprites and Binomes inside a system she infects will happily go to their deaths for her sake.
• Contrasting Sequel Antagonist: Following Megabyte, an Obviously Evil beast of a virus who embodied Dark Is Evil carried out atrocities with an affable façade and never had any illusions of his actions serving any greater good than his own twisted ego, we have Daemon, an angelic, petite woman who is an example of Light Is Not Good, whose affable qualities are genuine, and who sees her goals as beneficial for the Net. Furthermore, Megabyte was an extremely personal enemy for Mainframe, which he is obsessed with conquering, while Daemon is a far more distant figure who sees Mainframe as just one more system among the countless she's already infected.
  • Also to Hexadecimal. While Hex is a Chaotic Evil virus who has the power to destroy but lacks the sanity and will to do so, Daemon is a Lawful Evil virus with no such qualms and just as much power.
• Crippling Overspecialization: She cannot crack Firewalls or form portals to closed off systems. For a Cron Virus, this is quite the Achilles' Heel. Also as Phong deduced there is a technical limit to how many systems she can infect before her powers start to weaken, hence why the Super Virus wanted to infect routers and gateways, but not all the millions and millions of individual computers themselves.
• Dark Messiah: Mike even acts as her televangelist as she seeks to cause the end of the Net.
• Early-Installment Weirdness: In Season 3 Daemon's character had clearly not been fleshed out yet, as she was blamed for sending the Web Creature to Mainframe and has put a ban on travel into effect in Web-operated systems. It's unclear why she would do the former and the latter flat-out contradicts her goal of opening the entire Net up to her influence and corruption. Both these actions are ignored by Daemon Rising.
• Everything Sounds Sexier in French: She calls Mike Michel, and has a French accent.
• Evil Cannot Comprehend Good: Discussed. Daemon is not programmed to be able to feel love or go against her purpose. She is thus fascinated by AndrAIa's ability to leave her game in order to return to Mainframe with Enzo through The Power of Love.
• Evil Versus Oblivion: When she fights Hexadecimal. She is the oblivion, Hex is the evil.
• Expecting Someone Taller: She looks more like a Sprite than a supervirus. However, she is far stronger than her appearance suggests. Mike the TV even Lampshades this.
  Mike: Well... yeah, where are the spikes? The fangs? The claws? You're a bit small for a supervirus, aren't you?
• Flying Brick: She flies, her finger can block the attack from a Mech that smacked Megabyte across the room, and she can go toe to toe with a super-powered Hexadecimal.
• Getting Smilies Painted on Your Soul: In this case, it is more like getting ":-D" Copied and Pasted Into Your Code, which is a secondary part of her infection. All of her brainwashed slaves are blissed out.
• Heroic Sacrifice: Evil variation — her servants will prefer non-violent methods, no matter how deadly the opposition. Of course, she can afford the losses.
• Humanoid Abomination: Out of all the viruses to attack Main Frame, Daemon is both the most humanoid, and the most powerful. Yet while she could pass for a Sprite at a glance, her offputting color scheme, living hair and eerily pleasant demeanor makes her deeply unsettling.
• Interim Villain: Fills in for Megabyte as the main antagonist until he returns from the Web.
• Invincible Villain: Daemon can infect anybody who attempts to oppose her and is indestructible. Only an empowered Hexadecimal is a match for her.
• Jeanne d'Archétype: She is an angelic woman with a French accent waging her own "Holy crusade" to unite the Net, complete with her own eventual "martyrdom".
• The Juggernaut: Daemon is nearly unstoppable. She doesn't even react to threats with physical force because she's almost impossible to damage and just mind controls them instead. It takes an empowered Hexadecimal to even slow her down.
• Karma Houdini: Daemon dies fulfilling her function; her plans are only defeated by the skin of the heroes' teeth, and Daemon herself is never made to pay for her crimes.
• Kick the Dog: After she infects Hexadecimal, who was at the moment a sprite, she treats her extremely coldy despite and beats her. Hex submitted to her like everyone else, but Daemon couldn't stand her becoming a sprite.
• Knight Templar: She thinks the only surefire way to eliminate pain, war, and fighting is to eliminate all existence.
• Light Is Not Good: She's pretty and angelic, with a sweet and polite nature. But she's also out to destroy the entire Net. Her crown also resembles a halo, her corruption were she brainwashes programs is the form of light, and her home-base resembles a holy church.
• Meaningful Name: In a Unix system (which Mainframe presumably is), a cron daemon runs regularly scheduled tasks. The "cron" term is short for "chronological", and their purpose is to merely count things in binary. This explains why Daemon's final plan involves counting down to deletion. Cron viruses don't exist, but they'd be potentially devastating for the net if they did, making her a perfect doomsday villain.
• Mind Control: Her main ability is to enslave people to her whims.
• Muscles Are Meaningless: She's a small waiflike Virus and is Nigh-Invulnerable. None of the other clearly more muscular characters stand a chance against her.
• Nigh-Invulnerability: She's effectively indestructible. When Mouse tries to cut off her head with her sword, it not only fails to hurt Daemon, it doesn't even cut her hair, while Mouse's sword shatters on contact.
• Omnicidal Maniac: Her plan basically involves committing genocide.
• The Pretty Guys Are Stronger: She's by far the most powerful antagonist in the series and looks the most like a normal Sprite of any virus seen in the series.
• Reality Warper: When shot at with an exploding bullet, she reverses its explosion and reassembles the bullet. Note that this took place in the infected supercomputer.
• Religious Horror: She's basically a Catholic saint who's been recast as a supervillain, and she's damned good at it.
• Secondary Color Nemesis: Though Daemon's design heavily features teal, her more prominent green and purple aesthetic makes her palette overall cold and ominous.
• Taking You with Me: When her own timer runs out, she decompiles herself, spreading a secondary infection through the Net that causes everyone who has been infected by her primary infection to start a 60-second deletion timer.

Daemon: I am Daemon. I am not an entity, I am a time. My time... is now. The word... is cron.

• Villains Out Shopping: When she's not actively carrying out her plans she's shown enjoying musical numbers her brainwashed cult members put on for her.
• The Virus: She takes over the entire Net.
• What Is This Thing You Call "Love"?: Her followers love her, but only because of the infection. Daemon is thus fascinated by what AndrAIa tells her about the love she and Matrix have for each other.
• You Have Failed Me: When one of her infected aides, Deacon, fails in his attempt to invade Mainframe, Daemon whispers a series of "ones" and "zeros" to him in binary code. He then continues the sequence, before ending with a final "...oh". He then explodes.

Lieutenant Chauncy

Voiced By: Michael Donovan

A Viral (infected) Binome who leads Megabyte's army.

---

• Heel–Face Turn: When the system is rebooted. Chauncey returns and is an officer in the CPU forces.
  • Heel–Face Revolving Door: However, it turns out he liked being a viral, and not only helps form the Mainframe Neo-Virals, he willingly offers his PID to Megabyte when he returns for reinfection.
• Mook Lieutenant: Is delegated many orders from Megabyte to his legions.
• Slouch of Villainy: Often buzzed by Megabyte when he is slacking on the job.

Other Characters

The User

The User is the owner of the computer that is Mainframe. He is He Who Must Not Be Seen because he's a human living in the real world, but he still plays a major role in the series, acting as an antagonist during the games. He is viewed by most of the inhabitants of Mainframe as some sort of god. Capable of both great evils (such as the sector-nullifying games) and goods (new files). The User is generally seen in game cubes under the guise of a Player Character which the inhabitants of Mainframe have to stop from winning.

---

• Ambiguous Gender: The use of male pronouns is purely conjectural, as we only ever see the User's input into the computer system. Most of the User's game avatars are male or have no discernible gender (pilotless vehicles, for instance), with the notable exception of the Barbie doll User from "Firewall".
• Cavalier Competitor: The user of Mainframe appears to be a casual gamer, rarely playing the same title twice nor bothering to familiarize themselves with quirky control schemes of older games.
• Collective Identity: It isn't exactly clear whether every game is played by the same User, so there may be more than one.
• Deus ex Machina:
  • Or rather, god outside the machine. His game cubes fill that role often; when they don't, they serve only to make a situation worse by dropping at the worst times possible. The User himself performs that role more directly at the end of season 3 when he initiates a system restore to save Mainframe after a system crash, which is the only time the User's physical presence is ever directly observed (we hear his keystrokes). His role is even lampshaded by Dot:
    Where's a game cube when you NEED one.
  • At least Turbo sees the User as a godlike being, as exemplified when Daemon infects Mainframe:
    She's here. User, have mercy on the Net.
• For the Evulz: The writers of Gigabyte and Daemon. Using their knowledge not to profit, but to create dangerous viruses that would crash all computers (including their own) around the globe, thus rendering themselves obsolete in the wake of the impending information Dark Age.
• Game of Nerds: The user of the system seen in episode Number 7 is obsessed with golf. Matrix finding himself stuck there, and in a fatalistic slump, was soon sick of the sport.
• God in Human Form: In the games they'll, depending on the game itself, control a playable sprite, but for them it's merely an avatar.
• God Is Evil: Justified, as The User is Obliviously Evil. They are unaware that they cause mass destruction and suffering to the sentient beings living inside the computer.
• The Ghost: The User never makes a physical appearance. All we ever see are the characters' interactions with his player characters.
• The Gods Must Be Lazy: Their negligence over maintaining and updating their computers often cause viruses to spread and infiltrate many networks, tears to crop up, and of course, inevitable crashes.
• Greater-Scope Villain: The people who create viruses are this, particularly Gigabyte and Daemon. They're directly responsible for the destruction and chaos the viruses create. In Daemon's case, she nearly destroyed the entire Net.
• Have You Seen My God?: Some people on the Net believe in many Users, others only in one true User above all. None know for sure whether the being is good to them or not.
• Hero Antagonist: Any time the User controls a heroic character in a Game.
• Humans Are Bastards: There are Users who simply seek to destroy, such as the one that upgraded Killabyte into Gigabyte and Daemon's unseen creator.
• Humans Are Cthulhu: The User is a dangerous implacable foe in the games, a creator of viruses that plague the Net, provider of upgrades, and repairer of the system. Guardians will flat out state its beyond their comprehension to predict or understand the way a User thinks, and there's no point trying.
• Obliviously Evil: The User obviously has no way to know that just playing a game on his computer can cause all sorts of suffering for the people living within. Guardian Bob is also of the opinion no user would ever knowingly release a killer-virus upon the Net (poor naive Bob).
• Obviously Evil: Mainframe's User seems to have a preference for very obviously evil-looking player characters — Red and Black and Evil All Over and Spikes of Villainy are common. The one time we see them select a player character, it's a Big Red Devil.
• Oh, Crap!: Many characters, both heroes and villains, react this way when a Game starts at a particularly bad time for them.
• Our Gods Are Different: How many gods are humans using a computer?
• Phrase Catcher: Many characters say "Oh no, not now!" or some variation on that, when the User loads a gamecube at a particularly bad time.
• Spirited Competitor: The user of the Supercomputer, much like the user of the ruined system in the episode "Icons", is a hardcore gamer, and will only play the hardest and fastest titles on the market.invoked
• Time Abyss: Zigzagged. As time in cyberspace moves in nanoseconds, when a game is not downloaded into the system, a second in the User's realm equates to over 31 years in cyberspace! When the user is playing against them, time moves at the same rate for both of them.
• Unwitting Instigator of Doom: The User causes all sorts of mayhem with their Game cubes in general. Mainframe's User also has a really bad habit of unwittingly starting a Game at the worst possible time for the protagonists.
