[[caption-width-right:251:"If I ever get out of here, I'm never playing another video game as long as I live."]]
->'''Portrayed by:''' Thomas Wansey
The main protagonist. A British teen who moves to America with his parents. His life turns upside down when a lightning bolt strikes his house, bringing the characters of his favourite video game to life. He is recruited by Ace Lightning as his reluctant sidekick, and [[WakeUpGoToSchoolSaveTheWorld struggles to juggle his school life, romance, and saving the world]].
----
* ApocalypticLog: Mark talks to his friend Pete via a webcam usually in every episode.
* AudienceSurrogate: Usually the primary P.O.V. in the series.
* BadassNormal: At first he hides during early battles but then confronts Random Virus repeatedly, fights Zip and Snip, Pigface, and Fred separately using makeshift weapons, and is even willing to fight Lord Fear.
* BeleagueredAssistant: Mark is very reluctant to be Ace's sidekick at first, worrying about the danger and consequences, which show themselves through Season 1. He mellows out over time, but still has a cautious attitude to it. Played straight in early episodes where Mark has to bring some reality to Ace's programmed understandings of his own life.
* BigDamnHeroes: Pulls this if the other Lightning Knights at in trouble. His greatest traits are his courage and loyalty to his friends.
* BigNo: In the final episode where [[spoiler: Mark thinks Ace as been mortally wounded by Lord Fear, but it is revealed to be Lady Illusion in disguise]].
* ConsummateLiar: Becomes this to protect his friends from harm. While Samantha eventually comes to the conclusion it is one reason why she likes him, Heather is not so forgiving, and Kat easily sees through Mark's lies.
* DisguisedInDrag: Played with hilarious results in the ninth episode. Mark dresses up as a teenage American girl compete with an exaggerated ValleyGirl accent to keep an eye on Samantha. Wayne falls in love with his female counterpart. HilarityEnsues.
* EasilyForgiven: A subverted, non-evil version. Mark is easily forgiven over and over by Samantha for his habit of running off and making excuses. Heather, not so much.
* EnemyMine: Reluctantly agrees to aid Lord Fear in destroying Kilobyte.
* {{Expy}}: Mark was inspired by [[ComicBook/SpiderMan Peter Parker]].
* IJustWantToBeNormal: Though technically he ''is'', it's just the life going on around him which ''isn't'' normal in any way whatsoever.
* KidHero: A 13-year old hero with no superpowers. Until the second series, anyway.
* KidSidekick: The Robin to Ace's Batman (though Ace isn't really like Batman).
* TheLancer: To Ace, though he is still the show's lead protagonist.
* LightningGun / ShockAndAwe: Gets his own wrist cannon in the second series which fans have affectionately called "The Super Glove of Doom". It does have a strong resemblance to the [[Film/TheWizard Power Glove]].
* {{Narrator}}: He never directly addresses the audience, but rather shares video messages with Pete describing his experiences with Ace and co.
* OrdinaryHighSchoolStudent: Before becoming a superhero's sidekick, though he tries to maintain this trope throughout.
* RefusalOfTheCall: Mark repeatedly refuses to become a superhero, at one point quitting the superhero business all together after Sparx openly insults his abilities as one.
* ReluctantWarrior: Mark keeps saying throughout the series that he is not a hero or a Lightning Knight. He eventually accepts his role.
* SadisticChoice: Mark nearly has one in Episode 26 when he's given the tedious decision whether or not to delete the game from his computer, which would delete all the character too. He doesn't go through with it, of course.
* SupportingProtagonist: He is technically this to Ace, but is the main protagonist of the series.
* TenMinuteRetirement: Mark quits the superhero business for half an episode.
* TookALevelInBadass: Gets a lightning-shooting glove in the second series and joins in fights for the rest of the show.
* WakeUpGoToSchoolSaveTheWorld: That's pretty must the jist of this show - with video game characters. Mark even appears lampshades this: "First save the world, then be home in time for dinner."

!!Chuck Mugel
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning2.png]]
[[caption-width-right:350:"Oh, sweet, dude!"]]
->'''Portrayed by:''' Marc Minardi
Mark's best friend. A jolly, overweight nerd who is a big fan of Ace Lightning, aiding Mark with tips on how to beat the game without any knowledge of the truth. Though often bullied, Chuck is quite bright and has know-how on computers. In the second season, he discovers the truth and become Ace's secondary sidekick and TechnoWizard.
----
* CloudCuckoolander: His TotallyRadical personality and exciteable nature emphasize this. In the fourth episode, he is exposed to one of Lady Illusion's bombs, making him delirious, and starts singing "My Lord Kumbaya".
* DemonicPossession: Chuck is possessed by Rotgut in Episode 36. Chuck doesn't seem harmed by it, other than Rotgut has taken over his body, not that he does much harm with it.
* DiegeticSoundtrackUsage: Chuck whistles the theme song in the thirty-seventh episode.
* DisappearedDad: Chuck's father is never mentioned nor seen.
* EmbarrassingNickname: Wayne calls him "Upchuck" for his vomiting habit. Chuck calls his superpowered foot "Thunderfoot" for a short time.
* FatBestFriend: A mixture of all three types.
* FullNameUltimatum: Jessica calls Chuck by his full name when angry - "Charles Nelson Mugel".
* HiddenDepths: Reveals a significant knowledge with computers, technology, and engineering as the series progresses.
* LaserGuidedAmnesia: Chuck is hit by Lady Illusion's gas bomb in the fourth episode, meeting Ace, but Ace tells Mark that Chuck won't remember a thing once the gas wears off.
* LovableNerd: Nerdy, smart, chummy, bullied, wears glasses, likes video games and nerd-associated stuff, easily flattered and excited, but very humble at heart.
* MommasBoy: Implied, since his mother, who is a lawyer, sued the school bus company after Chuck threw up in it due to motion sickness.
* NerdGlasses: Gains them in the second season.
* NewAndImproved: Chuck pretty much describes himself as this in the first episode of Season 2.
* NoSocialSkills: Subverted. Chuck is just waiting to have someone to socialise with, and befriending Mark allows him to hang out with the likes of Samantha, Brett, and Heather.
* NotQuiteDead: Chuck is almost killed by a rampaging Ace, but recovers.
* OfficialCouple: With Jessica. Out of all the cast, they have the most stable relationship.
* PluckyComicRelief: Pretty much the funniest character in the show. His habit of being sick is often used as a RunningGag, and his tendency to overreact to events.
* ProudToBeAGeek: He is often bullied for his weight and nerdy status, but it barely bothers him. He reminds Wayne that some of the greatest minds in history were laughed at but did great things.
* RebelLeader: A non-standard example. Chuck rallies the students to rise up against Mr. Cheseborough's [[Literature/NineteenEightyFour Big Brother-esque]] routine in the twenty-fifth episode after, particularly after he finds out the food budget has been cut in the school cafeteria.
* SecretKeeper: Keeps Mark's secret after discovering Ace's existence in the second season. He briefly found out early in the first, but due to being hit infected by Lady Illusion's gas he forgets about it.
* {{Sidekick}}: To Mark, and then Ace.
* TheSmartGuy: The tech expert for the heroes.
* SuperpowersForADay: Chuck gains superhuman strength after being struck by a deflected lightning bolt. It wears off just before he's due to win a big soccer game.
* TheSmartGuy: Despite being bullied, Chuck is quite intelligent, building is own robot with help from Mr. Cheseborough and spends time at a computer camp.
* SweetTooth: Loves himself some chocolate or soda.
* TechnoWizard: Chuck is a gifted child, able to construct his own robot to win a tri-county science competition. His knowledge of computers, and the video game, make him the perfect recruit for the Lightning Knights.
* TrappedInTVLand: Chuck gets sucked into the video game, dons Ace's costume, and helps Sparx fight Googler and escape the game.
* VomitChainReaction: Chuck has a nasty habit of being sick, usually from motion sickness or when he sees something disgusting. These include being on a school bus, finding a pea in his pudding, or being creeped out by Rotgut. Can be used for great effect in humiliating Wayne or being used as a distraction.

----

* RollerbladeGood: Samantha has rollerskates but she never uses them.
* SassyBlackGirl: Has her snarky moments, but is usually very sweet but honest.
* UnresolvedSexualTension: After she and Mark part ways, Samantha shows a look of regret, perhaps having not given up completely on him.
* WeirdnessCensor: Samantha is oblivious to the strange goings on around her and their obvious link to Mark, merely pondering on them at some points as being odd. She is also attracted to Mark for his strange behaviour, grows tired of it but then is drawn back to him, realising why she loves him to begin with.
* WillTheyOrWontThey: With both Mark and Brett, Samantha has a hard time staying with one boy for too long.

!The Lightning Knights
The heroes of the show, the Lightning Knights are [[GuardianOfTheMultiverse interdimensional superheroes]] who guard the Sixth Dimension from evil. Their authority spreads to other worlds when Ace Lightning chases Lord Fear to Earth. While only three official members are introduced in the series, WordOfGod revealed that there were more Lightning Knights, some of which are stronger than Ace and Random Virus combined. As you may have guessed, the Knights are themed around electrical {{Magitek}} and medieval knight motifs. They operate from the Thunder Tower, actually Conestoga Hills' abandoned observatory, and use a transformer to recharge their powers.

[[folder:General Tropes]]
* ArmedFemalesUnarmedMales: [[{{Cyborg}} Random Virus's]] only weapons are his PowerPincers, SuperStrength and limited {{Technopathy}}, while Ace very rarely uses his lance and shield, relying mainly on his strength, speed, flight and lightning bolts. Sparx, on the other hand, relies entirely on her sword in battle.
* BlondeBrunetteRedHead: Ace is the blonde, Random is the brunette and Sparx is the redhead.
* ChromaticArrangement: Ace shoots blue lighting, Sparx shoots pink lightning and Random's eye glows green when he's a hero.
* FighterMageThief: Random is the fighter being a super strong CloseRangeCombatant. Ace is the mage due to having the most versatile powerset with super strength, super speed, flight, lightning bolts and fire rings. Sparx is a thief relying on her agility and sword to fight but is the weakest of the trio.
* FreudianTrio:
** Id: [[FieryRedhead Sparx]]--fiery, energetic, cocky, always jumping into action without thinking.
** Ego: [[TheHero Ace Lightning]]--idealistic, naive, courageous, fails to understand [[WhatIsThisThingYouCallLove human emotions]], TheLeader.
*** (Except when he ''gets'' human emotions and goes a bit ''Id'' on us).
** Superego: [[CyberneticsEatYourSoul Random]] [[NamesToRunAwayFromReallyFast Virus]]--has a SplitPersonality and is constantly struggling between the two.
* GuardianOfTheMultiverse: Their job is to protect the 6th Dimension and other dimensions from evil.
* KnightInShiningArmour: They are superheroes known collectively as Lightning Knights.
* MaleMightFemaleFinesse: Ace and Random have SuperStrength and are more likely to mix it up in close range. Sparx is physically the weaker of the three and relies entirely on her sword for offense.
* PinkGirlBlueBoy: Ace shoots blue lightning while Sparx shoots pink lightning.
* ShockAndAwe: Ace can fire lightning bolts from his wrist cannons and Sparx's sword shoots lightning as well. Random's {{Technopath}}y has been shown to produce an electrical effect.
* TeenageMutantSamuraiWombats: The Lightning Knights are knight-themed superheroes from another dimension stuck in the human world and aided by an ordinary teenage boy.
* TwoGuysAndAGirl: Ace and Random are guys while Sparx is a girl.
* YellowLightningBlueLightning: Ace shoots blue lighting. Sparx shoots pink lightning.

!!Ace Lightning
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning1.png]]
[[caption-width-right:350:"Just follow the code of the Lightning Knight: Do right and fear not."]]
->'''Voiced by:''' Michael Riley
The titular character and secondary protagonist. The player character of Mark's video game, ''Ace Lightning and the Carnival of Doom'', Ace is a Lightning Knight who follows Lord Fear and his gang to the real world to defeat them and restore the broken [[MacGuffin Amulet of Zoar]]. However, his time on Earth alters his original programming, discovering new emotions and experiences, including falling in love with Lady Illusion.
----
* TheAce: As his name implies, Ace is regarded as the foremost of the Lightning Knights. He is a skilled fighter and superhero.
* ArtificialHuman: A subverted trope, since he originates from a video game and is made of data. Discovers the truth in the finale, has a brief existential crisis, but Mark convinces him that he is a real person.
* AsskickingLeadsToLeadership: His duty as a superhero and Lightning Knight aren't really needed to show he can put up a fight.
* BigDamnHeroes: Usually pulls this off once an episode.
* BrainwashedAndCrazy: In one episode, Ace is turned into a zombie by Googler's sock puppets.
* BroughtDownToNormal: Ace's superpowers are removed by Zip and Snip, and he has to walk around disguised as a masked police officer.
* CharacterizationMarchesOn: Ace starts off as a wisecracking and heroic stock superhero, but over time he becomes more human during his experiences in the real world, developing romantic feelings for Lady Illusion, and an understanding for Mark's struggles as his sidekick.
** In the second season, Ace's original, already faultering programming is destroyed when Lady Illusion gives him real human emotions, making him undergoe a variety of changes but also gain intuition and an understanding of human spontaneity and relationships.
* ChasteHero: Ace admits he has never flirted before, and he is a 32-year old. However, this can be justified since he is a video game character and his programming likely didn't involve romance (cutscenes from the actual game show Lady Illusion flirting with him quite brazenly, with Ace completely unfazed by all of it). This changes when he and Lady Illusion get up close and personal, bonding over their misplacement in the world.
* ChestInsignia: A lightning bolt.
* CurbStompBattle: Quite good at this early on in the series, or when he is battling the second tier badguys.
* DatingCatwoman: Ace dates Lady Illusion, although it is in secret for most of the first season.
* DoesNotKnowHisOwnStrength: The former TropeNamer was AceLightningSyndrome. Ace's superhuman strength causes him to unintentionally trash Mark's house throughout the first season. Amongst the victims are Mark's bedroom window, the backdoor, the blender, a hand dryer in the school, and Fiona Hollander's treadmill.
* DumbBlonde: Subverted. Ace has his moments of stupidity, not understanding the lifestyles of Earth or Mark's social life. But outside of that, he's plenty smart.
* FishOutOfWater: Ace is bamboozled by Earth, often fiddling with technology in Mark's house and destroying it. He also develops a hatred for garden gnomes, although this stems from enemies in the game. Ace again fits this trope when he experiences his new emotions in the second season. It also provides a romantic subtext when he and Lady Illusion bond over their unfamiliarity with the world.
* {{Flight}}: Ace can propel himself to fly at the speed of electricity.
* TheGameComeToLife: At the beginning of the series, Ace, following his programming, is committed to being a superhero, fighting evil, and winning the game (though he is oblivious of the actual game til the series finale). He also views Mark as his sidekick and not as a friend, is puzzled by the real world, and is portrayed as a stereotypical superhero. Over time, he mellows out and evolves into a more humane character.
* GlassCannon: Becomes this when he is low on power.
* HeroicBSOD: Ace literally has one when he is frozen in place when a virus interrupts a data transfer. Lady Illusion snaps him out of it with their FirstKiss.
** Has more serious ones in the second season upon getting human emotions, terrified of Kilobyte and frightened when he nearly kills Chuck.
* HeroicVow: The code of the Lightning Knights - "Do right and fear not."
* ICanStillFight: Not as stubborn as Sparx, but will try to keep up the fight until it is time to retreat. Has a more personal version after falling into depression over his emotions, losing the will to fight. However, Mark's courage inspires Ace to do his job and be a hero.
* KnightInShiningArmor: While he never dons the traditional armour, but is chivalrous, heroic, and always trying to save the day. He also uses a lance and a shield in battle, and is called a Lightning Knight.
* LightningGun: Ace has two "wrist cannons" which he fires his electrical attacks from.
* LuckilyMyShieldWillProtectMe: Has the Shield of Justice, which can absorb energy blasts and redirect them. It's notable that while the Shield of Justice does show up in the game, it works like a generic InvincibilityPowerUp.
* MyGreatestFailure: Has two. One is accidentally crippling Lord Fear, leading to his rise to villainy. The other is being unable to help Random Virus' mental trauma.
* TheNicknamer: Often refers to Mark as "Kid", Chuck as "Chuckdude" (due to a misunderstanding), and nicknames the villains teasingly.
* OminousVisualGlitch: Will flicker a lot when low on power.
* PaperThinDisguise: Happens several times. He dresses as a hooded janitor to save Mark in the fourth episode; dresses as a masked police officer when Googler steals his powers in the seventh; and as a motorcyclist wearing a helmet during his stakeout with Mark to keep an eye on Samantha.
* PlayingWithFire: Ace gains an ability called "Ring of Flame" which projects small rings of fire.
* ThePowerOfFriendship: At first he views Mark as his sidekick, claiming Lightning Knights aren't friends but just superheroes. Though he comes to learn friendship is an important thing in life.
-->'''Ace:''' A friend is someone who looks out for you. Someone who will be there for you when you're in trouble. Someone who cares.
* PungeonMaster: Often has quips for every battle.
* RunningGag: Ace often breaks objects in Mark's house, usually out of curiosity although some cases he thinks he has done wrong and breaks them. Mark's parents never learn how the objects break and blame "shoddy American construction." Such victims of Ace's curiosity include a blender, Mark's backdoor, the handle of a fridge, Mark's bedroom window, and a running machine owned by Mark's mother Fiona. Ace also destroys several garden gnomes, and a hand dryer in the school. Ace lampshades this in the finale of the first season when he successfuly evades breaking Mark's window again.
** Got Mark's name wrong in early episodes, and then mistakenly calls Chuck by "Chuckdude".
* ShockAndAwe: Ace uses lightning in all of his battles and can even turn it into multiple forms - including spears, a lasso, an energy ball, and can create a wall of electricity which envelopes Ace and causes him to disappear.
* SpaceCop: Operates in the Sixth Dimension, but is implied to have authority elsewhere too.
* SuperStrength: Able to lift up Anvil with two hands, raise a car with one, and crush Mr. Cheseborough's car by falling from the sky.
* SuperheroesWearCapes: Averted. At one point, Ace comments he would hang up his cape if he had one, and a place to hang it.
* TokenFlyer: Ace is the only one of the three Lightning Knights who can fly under his own power. Sparks has a [[FlyingCar flying bike]] and Random Virus doesn't have any flight abilities or vehicles.
* WelcomeToTheRealWorld: Ace has a hard time getting used to Earth, breaking things, and finds human relationships bizarre.
* WhatTheHellHero: Ace goes a bit crazy when he first gains his emotions - he shouts at Mark, attacks Random Virus ''after'' he came to help him, and even accidentally shoots Chuck with a lightning bolt although he survives. This snaps him back into sanity, though doesn't stop him from blowing his top in later episodes.

[[caption-width-right:350:"I've been itching for a little action! Let's kick some villain butt!"]]
->'''Voiced by:''' Deborah Odell
A young, fiery Lightning Knight summoned by Mark partway through the first season. Impulsive, arrogant, and always eager for a fight, Sparx's ego is only matched by her loyalty to Ace. A skilled gymnast, swordswoman, and flies on a hovercraft called the Lightning Flash.
----
* ArrogantKungFuGirl: Sparx is a skilled martial artist, but with it comes great arrogance that often gets her into hot water.
* BloodKnight: She enjoys fighting just a little too much.
* BreakoutCharacter: Definitely a fan favourite out of the heroes.
* CatFight: Usually commences one whenever she and Lady Illusion cross paths.
* CoolBike: The Lightning Flash, a hovercraft that looks like a shark-shaped jetski.
* CoolSword: The lightning-spewing Sword of Jacob.
* DamselOutOfDistress: [[DamselInDistress Even when she's captured]], Sparx is still crafty. In the first season, Sparx convinces Dirty Rat to start a rebellion against Lord Fear as a distraction so Ace can rescue her. Occasionally falls into DamselInDistress territory anyway.
* {{Determinator}}: One thing Sparx can be counted for is that she will never give up even if her butt is being kicked.
* EstablishingCharacterMoment: Sparx makes her debut by blasting Anvil with lightning and leaping into battle, taking on Lord Fear.
-->'''Sparx:''' I've been itching for a little action. Let's kick some villain butt!
* FieryRedhead: A textbook example. HotBlooded, OneOfTheBoys, and a badass. CharacterizationMarchesOn thankfully and she becomes a more sensible and empathic person.
* TheGhost: In the real-world game that the one in the show is supposedly based on, bizarrely. The intro sequence mentions her existence and she waves goodbye to the player along with Ace and Random under the end credits, but is otherwise nowhere to be found.
* HeroesPreferSwords: Sparx has the Sword of Jacob, and Ace uses the Lightning Lance.
* HoistByHisOwnPetard: [[spoiler: She is struck by her own sword's power, leading to her game death.]]
* JerkJock: Comes off as this in her early episodes, but she mellows out a bit.
* JerkWithAHeartOfGold: Sparx is generally cocky and a bit too eager to fight. But she clearly cares about Ace and takes her job as a superhero seriously. She also apologizes to Mark to for her insensitive
* TheLancer: To Ace.
* TheRival: Has a very violent rivalry with [[DesignatedGirlFight Lady Illusion]]. She also has one with Googler.
* ShockAndAwe: Can fire pink lightning from her sword.
* SixthRanger: Another hero who joins the show later on. Sparx being brought into the real world is kind of the signifier in both seasons that things are starting to get really serious.
* TheSmurfettePrinciple: She is the only female Lightning Knight.
* ATragedyOfImpulsiveness: Subverted. In season one, Sparx is "[[DisneyDeath killed off]]" by Googler and sent back to the game after blindly attacking him. Ace and Mark summon her back later on. That doesn't mean it wasn't painful seeing her go, or that they didn't struggle without her while she was gone.
* XtremeKoolLetterz: It's not "Sparks", it's "Sparx".

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning6.png]]
[[caption-width-right:350:"How can you trust me, when I can't even trust myself?"]]
->'''Voiced by:''' Creator/CalDodd
A 35-year old Lightning Knight and an old friend of Ace. He became a cyborg in an undisclosed accident, but [[MurderousMalfunctioningMachine his mind was scrambled]], creating a SplitPersonality that causes him to change alignments. Because of this, he hides away in Conestoga Hills' junkyard, and is often sought by Ace and Lord Fear for recruitment.
----
* AffablyEvil: Happens on and off. Random's evil side is a psycho, but he won't attack Mark when realizes he is a CowardlyLion. Though in later episodes, he attacks Mark regardless of his bravery.
* AllThereInTheManual: The official guidebook explained Random became a cyborg through an accident, though it doesn't elaborate any further.
* ArtificialLimbs: Random lost much of his body in an offscreen accident, resulting in the loss of his legs and his right arm. He now has caterpillar tracks and a large claw instead.
* TheAtoner: His good side.
* AxCrazy: His evil side is hellbent on crushing weakness.
* TheBerserker: Becomes this if his evil side is really riled up, and it takes [[EnemyMine Ace Lightning and Lord Fear]] to beat him down.
* BigDamnHeroes: Random repeatedly pulls this off in the series, though on the last occasion, an emotionally unstable Ace blindly electrocutes him, causing Random to storm away in anger. Though he comes back to save the day two episodes later.
* ByronicHero: Has some traits, volatile in his emotions, stays by himself for the safety of others, etc.
* ChainedToARock: Lord Fear chains Random up when he tries to join the villains, unsure if he can be trusted let alone controlled.
* CloseRangeCombatant: Relies on melee combat more than
* CorruptCop: Only when his evil side is in control.
* CurbStompBattle: When he enters the fight, the battle will end quickly. Kicked Lord Fear's ass in seconds on multiple locations. Also the only character to take out Kilobyte alone and win.
* {{Cyborg}}: An unspecificed incident let to his mismatched cybernetic appearance.
* DarkAndTroubledPast: Physically and mentally injured, leaving him as a cyborg with a split personality. Talk about internal conflicts.
* DownInTheDumps: Random hangs around in a junkyard and is quite depressed, so it suits him.
* TheDreaded: At first for Mark, terrifying him with his power and appearance. But Mark eventually overcomes his fears and goes to Random for help several times. Lord Fear comes to see him as this.
* EvenEvilHasLovedOnes: Ace still treats him as a friend even when he is trying to kill him.
* EvilCannotComprehendGood: His evil side views all things good, heroic, and peaceful to be weaknesses, though he understands when people display courage.
* FallenHero: Ace often reminds him of this, causing Random to join in the fight as a hero.
* FrankensteinsMonster: Looks like someone thought it would be a good idea to turn him into a cyborg using scrapmetal from a junkyard.
* HeelFaceRevolvingDoor: Switched sides a lot, often due to his personalities or manipulation by the villains.
** Acts as something of a PowerLimiter in the first season where he can easily flatten any other game character, and hence is courted by both sides but neither are able to hold onto him thanks to his unstable personality. Less noticeable in the last thirteen episodes, where the other Lightning Knights get stronger attacks and the Evils get a new leader specifically created to dominate everyone else in the game.
** He chooses the side of good in the finale when Kilobyte poses the question of which side to take.
* HopeBringer: Surprisingly, Random becomes this multiple times for Ace, Sparx, and Mark when the chips are down.
* ImplacableMan: The most powerful character til Kilobyte comes along. He is immune to most attacks, can take on both Ace and Lord Fear at once, and it takes redirected blasts or more than one energy attack to bring him down.
* JekyllAndHyde: Rather than a physical transformation, but a mental, emotional one.
* KickTheDog: Doesn't do this often, but takes pleasure in insulting Ace when he turns into a coward.
* KnightInSourArmor: His good side is depressed and worried he will harm others, while his evil side is a psycho.
* LightningGun: Random has a wrist cannon but only uses it in the game, and shoots fireballs from it. His evil side, which is seen more often, appears to prefer doing things hands-on.
* MightyGlacier: Random has strength on par with Ace but is slower and less agile.
* OneManArmy: Virtually unstoppable unless disabled by numerous attacks. Has been able to defeat Anvil, Lord Fear, and Ace all in quick succession, before the latter two teamed up to take him down.
* PetTheDog: To Mark in their first encounter when he comes to rescue Chuck's stolen robot despite being terrified.
-->'''Random:''' He is afraid, but he is not a coward.
* RedEyesTakeWarning: His right eye turns red when he's in killing mode.
* RedGreenContrast: When Random Virus is evil, his cybernetic eye glows red. When he's good, it glows green.
* RoaringRampageOfRevenge: When his evil mode is in control.
* RollerbladeGood: Random's legs have been replaced with large black caterpillar tracks one might see on tanks. [[MightyGlacier This gives Random the least amount of mobility among the three Lightning Knights]].
* ScrewThisImOuttaHere: In the second season, Random willingly comes to Ace's assistance fighting Lord Fear, unaware Ace has just suffered from Lady Illusion's EmotionBomb. The emotionally confused Ace zaps Random with a lightning bolt and claims he didn't ask for his help. The enraged Random leaves, vowing never to help Ace again. Though this vows disappears when he sees Ace falling apart and they become allies again.
* ShadowArchetype: His evil side is this to Ace, doing what he thinks is "right" by wiping out all good in existence.
* SplitPersonality: The unseen accident that cost Random dearly scrambled his programming, leaving him with a good side and an evil side that way switch without a moment's notice. His good side wishes to aid the other Lightning Knights but is cautious of doing something he will regret forever, while his evil side is a violent psychopath who wants to wipe out all things good.
* {{Technopath}}: Able to control machinery, though we don't see much of this power.
* TrueCompanions: His good side values Ace and Sparx as this, coming to their aid in the first season's finale.
* TwoFaced: He doesn't mean to be.
* VillainousBreakdown: His evil side is slowly doing this during the second season.
* WeaksauceWeakness: Random can deflect most energy attacks but can be taken down a reflected energy attack, or if being blasted by more than one character. Also easily taken out by Kilobyte's energy-draining tentacles.
* WellIntentionedExtremist: His evil side views himself as this, believing all good and nice things are weak, and must be destroyed. It could be viewed as twisted sense of his duty as a Lightning Knight.
* WolverineClaws: Subverted. Now in the traditional style, but more of a large two-pronged claw resembling a car crusher.

!The Carnival of Doom
The bad guys of the series, also known as the Evil Gang but often called the Carnival of Doom. The villains are a group of freakshow-esque characters who live in an AmusementParkOfDoom. Lord Fear, the BigBad of the series, leads the carnival with the plan to conquer the world using the Amulet of Zoar's powers. He is later usurped by Kilobyte in the second season. The villains [[RevivingEnemy can constantly return after being defeated]] (i.e. spawning), morphing into locations around the carnival to rest and recover until their next appearance.

!!Lord Fear
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning7.png]]
[[caption-width-right:350:"Say goodbye, Ace Lightning, you superhero scum!]]
->'''Lord Fear voiced by:''' Creator/JuanChioran\\
'''Staff Head voiced by:''' Michael Lamport
The most feared supervillain in the Sixth Dimension, and Ace's arch nemesis. Lord Fear is a 352-year old lich, whose accidental crippling by Ace, was all the excuse he needed to plot world domination. Though a criminal mastermind, Lord Fear does often fall into cartoonish villain buffoonery. In a romantic relationship of some kind with Lady Illusion, but she soon has an affair with Ace. Lord Fear rules over the Carnival of Doom, operating from the Haunted House, and loves playing the pipe organ.

Suffering from a limp, he is aided by his minion '''Staff Head''', a pompous bat-frog-gargoyle creature who perches on the end of Fear's staff. In the second season, Lord Fear receives the [[CoolBike Doom Wagon]] from Kilobyte.
----
* AllPartOfTheShow: Lord Fear tries to gain the final piece of the Amulet during the school's performance of ''Theatre/ThePhantomOfTheOpera'', but sees the audience applauding him and he joyfully sits down and plays a pipe organ. Mark decides to include him as the Phantom since Chuck (who played the Phantom and wore a Lord Fear-styled) threw up and is offstage.
* AmusementParkOfDoom: Make that Carnival of Doom. Lord Fear's domain is a nightmarish funfair in the Sixth Dimension. In the real world, his gang occupy the rundown Kent Bros. Carnival.
* AsskickingLeadsToLeadership: He is called the Master of Fear for a reason...
* BadBoss: He will abuse and insult his minions when they fail him, usually Dirty Rat or Duff, but can also pleased if they serve him well.
* BadassBiker: Lord Fear becomes even more awesome when he gets the Doom Wagon, a rocket-powered motorcycle-hovercraft with a [[ChainsawGood chainsaw]] on the front.
* BadassBoast: "I too have learnt a valuable lesson - if this friendship gives Lightning and his lackey strength, it can also be used against them. I will have my vengeance for how he crippled me in battle, and then, I'll unleash all the terrors of the Sixth Dimension on this worthless world!"
* BigBad: For the first season until Kilobyte comes calling, forcing him to become TheDragon.
* ButtMonkey: Becomes this in the second season thanks to Kilobtye taking over. He eventually teams up with Ace to get revenge.
* CardCarryingVillain: Lord Fear enjoys the life of a supervillain, scaring children and defeating his enemies. It's good to be bad.
* CoolBike: The Doom Wagon. Concept art showed the vehicle was going to be more bike then hovercraft with two skeletal carousel horses pulling it like a chariot with big monster truck back wheels and a pipe organ/coffin theme.
* CoolOldGuy: Three centuries old, can play the pipe organ, wants to take over the world.
* DemBones: He is a lich after all, though this doesn't stop him from doing things a normal skeleton could do.
* DemotedToDragon: Kilobyte demotes him to this after taking over.
* DiabolicalMastermind: Set up as this in the game, being a criminal mastermind who stole the Amulet of Zoar.
* DisproportionateRetribution: God help you if you interrupt him when he is playing the organ.
** Being accidentally crippled by Ace led him to want to conquer the world and destroys humanity.
* DragonWithAnAgenda: It is obvious he intends on defeating Kilobyte sooner or later, not that it bothers him much. He eventually teams up with Ace to defeat Kilobyte.
* EnemyMine: Teams up with Ace twice in the series. The first is briefly to take out a psychotic Random, and again in the series finale to destroy Kilobyte.
* EvilLaugh: Very good at it.
* ExtendableArms: Lord Fear can extend his arms and neck like a boa constrictor. Utilises them usually to just yell at his minions from a far off distance or scare Wayne and his friends.
* FinalBoss: Programmed to be in the video game. Defeating him leads to victory of the Lightning Knights.
* ForTheEvulz: Does a lot of wicked deeds solely for power and being bad.
* FreudianExcuse: His crippling and imprisonment by Ace is all the excuse he needs to take over the world.
* HandicappedBadass: While his limp makes it difficult for him to walk, Lord Fear makes up for it with his intelligent, skills, and weaponry.
* HauntedHouse: Lives in the ghost train at the carnival, but an actual haunted house in the games.
* KickTheDog: Often gloats when Ace is down for the count and may attack him again for an extra cackle. Often mistreats Dirty Rat to when he crosses him, and takes great pleasure in watching Duff squirm.
* LargeHam: "Say goodbye Ace Lightning, you superhero scum!"
* LeanAndMean: A skinny sinister skeleton.
* LimpAndLivid: Lord Fear limps thanks to Ace, using Staff Head as support.
* LoveTriangle: Unknowingly gets into one when Lady Illusion, whom he loves, hooks up with Ace, whom he hates.
* TheNicknamer: Lord Fear often gives his allies and enemies nicknames. These include "Totem of Terror" for Staff Head, "Muscle-Bound Minion" for Anvil, and "Grinning Ghoul" for Googler.
* OminousPipeOrgan: He is a master of the pipe organ and never actually had a lesson.
* TheOnlyOneAllowedToDefeatYou: A primary reason for wanting to destroy Ace, and it doesn't help that he has Googler and Kilobyte to compete with.
* OurLichesAreDifferent: A standard version though it is not explained how or why he is a skeleton.
* RepulsiveRingmaster: As the leader of the Carnival of Doom, Fear qualifies.
* RevengeBeforeReason: Lord Fear's primary motive is vengeance against Ace after he crippled him. This extends to Lady Illusion after she betrays him for Ace.
* RevivingEnemy: Spawns from a skeleton in the Haunted House.
* RunningGag: Lord Fear keeps frightening Wayne and his friends whenever they come to the carnival.
-->'''Lord Fear:''' (after scaring Wayne) I always had a soft spot for that kid.
* SerpentStaff: Staff Head doesn't physically resemble a snake but can move by slithering across the ground like one.
* SkeletonsInTheCoatCloset: Aside from being a skeleton himself, he wears skulls on his belt and coat.
* SnootySports: Lord Fear develops a passion for mini-golf in the second season, growing to be quite snooty when it is time to play.
* TakeOverTheWorld: Rather destroy the world then leave to conquer other dimensions.
* TeethClenchedTeamwork: With Kilobyte throughout the second season.
* TheUndead: Of the lich, skeletal variety.
* VillainousFriendship: With Staff Head, and Dirty Rat, and Googler to an extent.
* WeWillMeetAgain: Promises this to Ace in the twenty-sixth episode upon his first defeat.
* WouldHurtAChild: Lord Fear has no problem trying to destroy Mark and Chuck, but playfully scares Wayne, and enjoys tricking children.
* XanatosGambit: Tries this in the finale, teaming up with Ace to destroy Kilobyte with the intention on then eliminating his nemesis. However, [[HeroicSacrifice Lady Illusion foresaw this coming]].

!!Tropes related to Staff Head.
* BatOutOfHell: Has bat wings but can't fly.
* {{Blackmail}}: Staff Head learns of Lady Illusion's relationship with Ace, he blackmails her to aid Lord Fear or he will spill the beans to His Lordship.
* CatchPhrase: "Oh, crikey!"
* DayInTheLimelight: Spends one episode in the company of Duff, Dirty Rat and Pigface while out hunting Mark in the wilderness. He still remains the biggest asshole all the while.
* DeadpanSnarker: Has his moments.
* TheDragon: To Lord Fear.
* EnergyWeapon: Fires magic energy blasts from his crystal ball.
* {{Jerkass}}: He pretty much treats every other character aside from Lord Fear like dirt. He seems to particularly hate Lady Illusion and Duff.

* WingsDoNothing: Can't actually fly.

[[folder:Lady Illusion]]
!!Lady Illusion
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning8.png]]
[[caption-width-right:350:"They have a saying in this world: Actions speak louder than words."]]
->'''Voiced by:''' Tamara Bernier
A shapeshifting villainess, Lady Illusion is Lord Fear's partner in love and crime. Despite being Lord Fear's lackey in the first season, Lady Illusion is more than capable of taking care of herself. However, shortly after arriving on Earth, she strikes out on her own only to form a forbidden romance with Ace. Caught in the HeelFaceRevolvingDoor for most of the series.
----
* AnimalMotifs: Spiders, since she has one for hair, and a web-design on her clothes. Most of her minions in the game share this motif.
* AxCrazy: Becomes super violent whenever around Sparx.
%% Doesn't explain what the reaction is * Berserk Button: Sparx's very existence is this.
* BigCreepyCrawlies: Giant spiders aid Lady Illusion in the video games.
* CatFight: She has numerous fights with Sparx. Their first one involves poor Ace gets knocked out twice while the two ladies beat the crap out of each other.
* {{Cloudcuckoolander}}: Not actually this, but when she disguised herself as Mr. Cheseborough, she portrayed him as this. She wasn't that far off from the truth.
* DarkActionGirl: You'd better believe it. This bomb-throwing, shapeshifting badass will beat you before even knowing its her.
* DatingCatwoman: At the beginning of the series, she is in a relationship with Lord Fear (he calls her "Snookums"). But six episodes in, she has grown fed up of Earth and wants out, so she steals Lord Fear's Amulet piece to find Ace's and escape to another dimension. However, when she finally meets up with him, the two find a connection feeling like FishOutOfWater, eventually falling in love. The two have an affair throughout the series.
* EmotionBomb: Upgraded by Kilobyte to give Ace unstable human emotions, which she comes to regret.
* {{Expy}}: Of [[ComicBook/XMen Mystique]]. Fittingly, Lady Illusion's actress would go on to voice Mystique in ''WesternAnimation/WolverineAndTheXMen2009''. Also has traits of Catwoman.
* {{Fireballs}}: In season 2, Kilobyte upgrades her crystal ball attacks into large, orange fireballs.
* GreenSkinnedSpaceBabe: Make that a green skinned interdimensional babe.
* HallOfMirrors: Lady Illusion appears as a boss in a hall of mirrors in the Gameboy Advance game.
* HavingABlast: Lady Illusion's main attack is creating crystal orbs which can either explode in a burst of fire or release a type of gas that leaves the enemy dazed.
* HauntedHouse: Lady Illusion owns a freaky funhouse in the PC and [=PS2=] games.
* HeroicSacrifice: [[spoiler: Lady Illusion disguises herself as Ace and is mortally wounded by Lord Fear.]]
* HighHeelFaceTurn: Her feelings towards Ace eventually lead her to do this at the end of the first season. However, a misunderstanding in the second season sends her back to Lord Fear's side and takes a lengthy spin in the HeelFaceRevolvingDoor.
* InASingleBound: Lady Illusion can leap from the ground to the top of the carnival's ferris wheel in one leap.
* MadBomber: Subverted. Lady Illusion often uses bombs to attack enemies but not all that insane.
* ManipulativeBitch: She can be manipulative when necessary.
* MasterOfIllusion: Pretty good at deceiving others using her shapeshifting powers.
* TheMistress: Implied to have a romantic relationship with Lord Fear. Even though he is a [[{{Squick}} skeleton]]. Lord Fear claims they are "programmed to be together".
* TheRival: To Sparx for some reason.
* ScrewThisImOuttaHere: Her original reason for ditching Lord Fear, but she returns to his side at the end of the episode. Albeit, with mixed feelings towards Ace.
* {{Shapeshifting}}: Able to transform into humans and animals. Uses this to great effect, destroying Mark's relationship with Samantha, and then tricking him into giving her the Lightning Knights' Amulet pieces to kick off the endgame. [[NecessarilyEvil Though not by choice]].
* TheStoic: Remains quiet and almost emotionless for the first few episodes.
* UndyingLoyalty: To Lord Fear, at first. By the end, she is this to Ace.
* VillainTeleportation: Performs this by spinning and vanishing in a flash of light.
* ViolentlyProtectiveGirlfriend: Lady Illusion is quite the rough-and-tough lover to Ace, willing to blow Mark, Chuck, and Sparx to smithereens to have Ace to herself. As soon as Sparx arrives in the show, Lady Illusion vows to destroy her. Staff Head asks if it is out of jealousy, but she instead claims it is for revenge, implying the two women know each other. Can go into {{Yandere}}-like traits at times.
* WallCrawl: Able to stick to walls and scale them.
* WouldHurtAChild: More than willing to blow Mark and Chuck to kingdom come.

!!Kilobyte
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ace_lightning9.png]]
[[caption-width-right:350:"You've wasted your power and so it shall be returned to its rightful master."]]
->'''Voiced by:''' Creator/TedAtherton
The BigBad of the second series. The Cyber Stalker, created by the Master Programmer to fulfil Lord Fear's role and prove his creator's own genius, Kilobyte wishes to destroy Ace as slowly and painfully as possible. Armed with CombatTentacles that can absorb energy and upgrade other characters. Flies around on a giant mutant wasp named Fred.
----
* AuthorAvatar: An in-universe example, Kilobyte is the avatar for Rick Hummel, the Master Programmer and villain of the series.
* AxCrazy: Always on the brink of turning into a psychotic maniac, but is calm and sociopathic enough to keep it together. Becomes completely bat shit insane after he is freed from Rick's control while still maintaining his focused attitude.
* BadBoss: Subverted. Kilobyte is like Lord Fear, abusing and punishing his minions when they fail, but tries to find [[BenevolentBoss value in all of them]] - even Rotgut. Though he does torture Dirty Rat even more than Fear, punching him every episode and forcing him to dig up Mark's garden to find a buried Amulet piece.
* BaldOfEvil: Bald and covered in tattoos.
* BigBad: For the second season, usurping Lord Fear and proving a vastly more competent, vicious and focused main villain.
* BigCreepyCrawlies: Fred, a giant mutated wasp Kilobyte uses to get around. Doubles as a his CompanionCube.
* BondVillainStupidity: While there's no doubt he's ten times the threat Lord Fear was, Kilobyte is ultimately undone by his desire to break Ace's spirit before finishing him off, and swinging back and forth between attacking the Lightning Knights or letting them go to make them suffer more depending on the convenience to the plot. By dragging things out, he ultimately gave Ace the chance to learn about and overcome his new human weaknesses, and for Lord Fear to decide to propose a truce to get rid of Kilobyte.
* TheChessmaster: Kilobyte manipulates the other characters, stealing the Amulet pieces from under Mark's nose and knows more about the game then anyone else. He breaks free from Rick's control and furthers his own agenda, eliminating or capturing the heroes, and plots to send humanity to the Sixth Dimension so the villains can rule the world without interference.
* CombatTentacles: Has four slimy green octopus tentacles that can be used to ensnare enemies or pin them down.
* TheComputerIsACheatingBastard: After Lord Fear and his minions were defeated, Kilobyte was created by the Master Programmer to give them a completely unfair boost in power. He was meant to be unbeatable by any other game character, and can easily defeat them by just touching them with a tentacle and sucking out their energy. More to the point he can upgrade the other villains with new or better powers, but usually only does so if they please him.
** Kilobyte also abandons any concept of fairplay. When he's ready to launch his master plan, the first thing he does is whittle down the Lightning Knights' numbers so there won't be any effective resistence. This he does by [[CombatPragmatist confronting them one at a time and hitting them with everything he has]], sending all the villains to attack at once and overwhelm one opponent.
* CowardlySidekick: Dirty Rat.
* DrunkOnTheDarkSide: Nuts about power.
* EvilOverlord: Overthrows Lord Fear to become this. Then intends on ruling the world as this.
* FaceFramedInShadow: Kilobyte's appearance is hidden in shadows throughout his debut episode as he observes Ace and Lord Fear.
* FauxAffablyEvil: Acts calm, focused, and at times complimentary towards his minions, but is ruthless, heartless, and only cares about crushing Ace and gaining power.
* FluffyTheTerrible: Fred. Lampshaded through dialogue:
-->'''Kilobyte:''' I named him...Fred.
-->'''Duff:''' You're gonna call that thing ''Fred''?
-->'''Kilobyte:''' What's wrong with Fred? I like it!
* FrankensteinsMonster: Minus the sympathetic elements. But it is his giant wasp Fred who more fits the role. Fred started off as an normal wasp that stung Kilobyte, absorbing his power and mutates into a giant, Kilobyte considering him a kindred spirit.
* GreaterScopeVillain: Twice as powerful as Lord Fear, Kilobyte was personally created by the Master Programmer to fulfill his ambitions and thus has knowledge of the game and information received through his creator's intel.
* HalfHumanHybrid: Half man, half octopus.
* JoinOrDie: Offers Random Virus this to escape oblivion, but Random would rather go out as a hero. Kilobyte is visibly disappointed and surprised by his choice.
* KickTheDog: Does this to Lord Fear at every chance, disappointed by his VillainDecay. Also backhands Dirty Rat at every chance.
** TheDogBitesBack: Kilobyte's defeated in the last episode when Lord Fear has enough and joins forces with Ace to have enough firepower to turn the tables.
* KnightOfCerebus: Kilobyte is the BigBad Lord Fear always fancied himself. There's nothing funny about him, he's competent from his first appearance and doesn't need anyone helping him to be a serious threat. His ability to bestow power-ups on the other villains makes him even more dangerous.
* MultiArmedAndDangerous: If octopus tentacles count.
* PetTheDog: Kilobyte shows genuine affection to Fred whenever they have a scene together.
** Always displays a surprisingly gentle, respectful demeanour around Lady Illusion. She is the only character he upgrades personally (though it is part of his plan to destroy Ace), rescues her during a battle with Sparx, and gives her a chance to explain her actions during her HeelFaceRevolvingDoor antics to gain another Amulet piece. He thanks her with a grose caressing of her facial cheek with his tentacle. However, he does warn her if she ever betrays him, she will suffer.
** Gives Lord Fear the Doom Wagon as a reward for proving himself worthy as an ally.
** Even manages to find talent for Rotgut by scaring the humans to lure out Ace.
* PowerAtAPrice: Kilobyte upgrades Lady Illusion to give Ace [[EmotionBomb unstable emotions]], briefly causing her to turn into a bitter and cruel individual. This doesn't last long.
* RevivingEnemy: Spawns from the ferris wheel.
* RunningGag: Kilobyte punches Dirty Rat in each episode when the rodent bothers him.
* TheStoic: Acts very calm, focused, and quiet. Even if there is a minor loss, Kilobyte remains calm. The more serious defeats is when he displays TranquilFury.
** NotSoStoic: After being freed from Rick's control, he becomes a bit more AxCrazy.
* TattooedCrook: He sports several tattoos on his head including two of fish skeletons on the back.
* TeachHimAnger: Kilobyte upgrades Lady Illusion with a new power that will infect Ace with human emotions, leaving him an emotional, out of control wreck. This plan ultimately fails when Ace learns to control and embrace his new feelings.
* ToCreateAPlaygroundForEvil: Kilobyte's ultimate goal at the end of the series upon being freed from Rick's control.
* TrappedInAnotherWorld: Trapped in the game by Ace, Mark, and Lord Fear's Trio, though he plans to get out.
* VillainDecay: Believes Lord Fear has suffered from this, becoming "soft like the mortals [he] was sent to enslave".
* VillainWorld: Kilobyte plots to trap humanity in the video game world and bring about all of the Sixth Dimension's villains to replace them.
* VillainousBreakdown: He is completely gobsmacked when Lord Fear reveals he has sided with Ace to defeat him.
* WeaksauceWeakness: Despite being almost invulnerable, having immense strength and the ability to either upgrade characters or suck out their energy, Kilobyte is fended off by flashlights a few times. It is never explained why. Game logic, I guess.
* WhyDontYouJustShootHim: Kilobyte could easily overwhelm and destroy Ace in a fight, but wants to drag it out by breaking his spirit first. This might seem like BondVillainStupidity, but we find out Rick brought the game characters to life to demonstrate his brilliance, and some theatrical tendencies would actually help attract attention and give him the attention he wants (even if getting that attention would get him locked up for the rest of his life).

[[caption-width-right:350:"Oh, I love this part of the job."]]
->'''Voiced by:''' Creator/AdrianTruss
A winged rat dressed as a clown, Dirty Rat acts as Lord Fear's spy but is no means a loyal one, being self-centered, sneaky, [[DirtyCoward cowardly]], and always [[TheStarscream looking for ways to gain power]]. Has a friendship with Duff Kent.
----
* AffablyEvil: Dirty Rat can be a decent guy when he's not being a coward or a jerk. He has a chummy frienship with Duff, enjoys teleshopping and Earth's culture, and would like to make money. Also finds Sparx good company.
* ButtMonkey: Usually the target for Lord Fear's anger if Duff isn't within firing range. Often humiliated on an episodic basis by Lord Fear, Kilobyte, or one of the heroes. He eventually snaps at the end of the first season when he gains a piece of the Amulet, briefly leading an uprising against Lord Fear until his boss produces Ace's piece of the Amulet leading to Rat's return to his side.
* DirtyCoward: Always the first to duck and cover when the Lightning Knights show up. If they are down for the count, he'll join the others for gloating and the victory party.
* TheDragon: To Kilobyte, though he shares this role to Lord Fear with Staff Head.
* JerkAssWithAHeartOfGold: A self-serving, snivelling, dirty coward but he can be a decent guy, complimenting Sparx for her confidence and encouragement.
* MistreatmentInducedBetrayal: He rallies the minions against Lord Fear for his BadBoss treatment towards them.
* MysteriousWatcher: Can be found spying on the Lightning Knights or mortals form a distance.
* TheNoseKnows: He has enhanced senses of smell and hearing, allowing to identify mortals from superheroes.
* RevivingEnemy: Spawns from a gargoyle that sits outside the Haunted House. This gives him an advantage to spy on the carnival's visitors.
* RodentsOfUnusualSize: A very large flying rat about the size of a small dog.
* ScrewThisImOuttaHere: Flees the carnival with Lord Fear in the show's finale.
* SidekickCreatureNuisance: Annoys Kilobyte to no end that he punches him every episode.
* TheSpymaster: Serves as Lord Fear's go-to-spy-guy.
* TheStarscream: Turns briefly against Lord Fear when he gains a piece of the Amulet, grows tired of his abuse, and is inspired to take a stand by Sparx.
* TalkingAnimal: A talking winged rat in a clown costume.
* VillainousFriendship: With Duff and Pigface, but also gets on well on and off with Rotgut and Lord Fear.
* VillainsOutShopping: The Rat is a big fan of a shopping channel, ordering purchases over the phone.
* YouDirtyRat: The textbook example, very sneaky, sinister, mean, and cowardly.

->'''Voiced by:''' Creator/HowardJerome
A rhinoceros who serves as the DumbMuscle of the group. Dresses in medieval wear and has an anvil for a hand. Not too smart, speaks in third person, and wants to [[HulkSpeak smash]] Ace.
----
* AnvilOnHead: Anvil has an actual anvil on his arm and has used it to bash a few people around, and has actually dropped it on Random Virus' head once.
* TheBrute: Big, dumb, short-tempered rhinoceros mook who is Lord Fear's muscle.
* DumbMuscle: Dumb as a brick, talks in HulkSpeak, too stupid to know anything but trying to smash Ace.
* FoeTossingCharge: Tries to pull this on Ace but runs headfirst into a dumpster, which Ace then chucks him in.
* [[MedievalMorons Medieval Moron]]: He's from the Dark Ages and not too bright.
* RevivingEnemy: Spawns from the carnival's strength-testing game.
* RhinoRampage: He is a rhino, is easily angered, and participates in a lot of fights. It is only once that he actually charges, and runs straight into a dumpster. Ouch.
* SmashMook: A little smarter than the usual standard. A little.
* SuperStrength: Capable of trashing trash cans, smashing gates, and going toe-to-toe with Ace. Has more of a challenge with Random Virus.
* TopHeavyGuy: Has a huge upper body and teeny tiny legs. Somewhat realistically, this results in Anvil walking with all fours.
* WarmupBoss: The physically most tough of the badguys until Kilobyte comes along.
** In the video game, Anvil counts as the FinalBoss with Lord Fear, Lady Illusion and Pigface.
* WhyDidItHaveToBeSnakes: Freaks out if alone in the dark.
* TheWorfEffect: Comes back in the second season claiming to be stronger, only to suffer the Worf Effect when Kilobyte arrives, pinning Anvil down and draining his power.

->'''Voiced by:''' Keith Knight
A 12-year old pig minion who came with Lord Fear to the real world. With a childlike mind and disgusting table manners, Pigface acts as secondary DumbMuscle, and thinks with his stomach.
----
* {{Acrofatic}}: Surprisingly agile for his weight and size.
* AffablyEvil: Essentially a kid who just wants to eat candy.
* BashBrothers: Implied with Anvil.
%%* Berserk Button: Don't insult his weight or interrupt him when he is eating.
* BigEater: Pigface raids the carnival's trashcans when hungry. Could count as an EvilCounterpart to Chuck.
* TheBrute: Shared with Anvil. The two are best buddies.
* ButtMonkey: After Dirty Rat and maybe Rotgut, he is usually the most poorly treated, and easily defeated, of the bad guys. Even in "Game Over" when the weakened Lightning Knights are getting owned by the villains, Ace ''still'' takes Pigface out easily.
* CoveredInGunge: Gains a new ability to spray power-draining snot from his nose. Hilariously disgusting. Kilobyte and Heather both get a faceful during the course of the series.
* DumbMuscle: More childlike then straight out dumb like Anvil, but still not very bright. Driven by his stomach than his brain.
* ExtremeOmnivore: Can devour anything including inorganic items like metal golf clubs and glass beakers.
* HulkSpeak: As per his status as the DumbMuscle, though it is also because he is childlike.
* ImAHumanitarian: Implied to eat people.
* JabbaTableManners: Pigface will fart, belch and pick his nose in public, although he seems sensitive to Lady Illusion's remarks about his habits. Lord Fear finds them useful - but not when Pigface farts right in his face.
* LightningBruiser: Surprisingly, despite his weight.
* PaperThinDisguise: Duff and Pigface are sent to "repair" Ace's recharging station after Anvil breaks it, with Pigface wearing a baggy coat to disguise himself. Ace isn't fooled.
* PigMan: An anthropomorphic boar with zero table manners.
* RevivingEnemy: Spawns from a garbage can (which suspiciously resembles him).

----
* AxCrazy: Completely maniacal and insane, and loving every minute of it.

* FantasticSlurs: He finds "zombie" to be one, but thinks being called the "walking dead" is dignified.

For the most he's an [[AffablyEvil affable]], LaughablyEvil, MinionWithAnFInEvil and has little interest in partaking in the other villains' {{Evil Plan}}s. He always politely greets humans and is dismayed when they run away in terror, enjoys singing folk songs, and at one time approached someone because he wanted a hug. He also believes Chuck to be his good friend due to the boy calling him "dude", even though Chuck [[TheFriendNobodyLikes has other ideas]].

Mark's science teacher, Mr. Cheseborough has little faith in his students and often insults and begrudges them, often taking pleasure in failing them. He encounters the villains early on when they kidnap him in one of their plans, causing him to believe they are aliens. He becomes slowly paranoid and crazy over the series.
----
* AgentScully: Becomes convinced he was abducted.
* AlienAbduction: From Mr. Cheseborough's point of view.
* {{Cloudcuckoolander}}: His repeated encounters with the "aliens" leave Mr. Cheseborough quite crazy, and in the final episode he pretty much flips out and is declared a public nuisance by the authorities.
* TheCuckoolanderWasRight: Subverted. Mr. Cheseborough's claims of alien abduction is technically true - he was abducted by inhuman creatures from another world.
* HorribleJudgeOfCharacter: Lord Fear and Duff trick Mr. Cheseborough into believing the villains are good aliens and Ace is evil, and to help Lord Fear kill him.
* InnocentBystander: Starts off as a grumpy old teacher but is abducted, imprisoned, and left a shifty, paranoid wreck.

->'''Portrayed by:''' Creator/PhilipWilliams
The owner of the Kent Bros. Carnival, turned into the Carnival of Doom by the villains, Duff is a middle-aged man who ends up becoming Lord Fear's slave. Very much the InnocentBystander, Duff dislikes working for the villains but goes along with it for most of the time. He befriends Dirty Rat, Rotgut, Pigface and Googler (sort of), and at times gets on well with Lord Fear. He also drives an ice cream truck as a secondary job, but the villains use it to get around.
----
* AmusementParkOfDoom: He doesn't want his family carnival to be one, though the creaking attractions and presence of supervillains makes his wishes a little tricky to grant.
* BadassBystander: In the season one finale, Duff finally turns against Lord Fear and tries to run him over, though he is back to serving them in the second season.
* BadHumorTruck: Subverted. Duff drives the Dairy Wagon, a harmless ice cream truck. It is the villains that travel in it that make it scary. In one episode, Duff and Lord Fear drive it around and occasionally use it for VehicularKidnapping.
* ButtMonkey: Poor Duff just wanted to run his family carnival, but the arrival of Lord Fear and his gang turns him into a reluctant servant and chaffeur.
* CartoonCreature: Refers to the video game characters as cartoons.
* CrappyCarnival: The Kent Bros. Carnival has been in business since the 1880s, but is rundown, has creaky attractions, and the carnies themselves come off as a bit dodgy. It has little thrill rides beyond a haunted house, ferris wheel, a tunnel of love, and a spinny thing. Duff tries to maintain a family friendly reputation, but it is difficult when you have supervillains running around.
* ADayInTheLimelight: In Episode 20, where he spends the whole episode on a psychiatrist's couch explaining what is going on.
* DirtyCoward: In one episode he seeks out Ace's help to try to get rid of Lord Fear, but when they're caught in the act Duff immediately changes his story and says he was luring Ace into a trap for Fear. He knows a hero isn't going to seek him out for revenge over that, but Lord Fear would.
* FreudianCouch: Duff spends the entirety of the twentieth episode on one.
* InnocentBystander: Shared with Mr. Cheseborough, not wanting to be involved in the war between the Lightning Knights and villains.
* OOCIsSeriousBusiness: An unusual subversion. In the official character guidebook, Duff is described as plotting to steal the Amulet to overthrow Lord Fear. This was actually Dirty Rat's plan, and Duff never even suggests such an idea.
* SomeOfMyBestFriendsAreX: Subverted. Duff's best friend is a flying talking rat.
* VillainousFriendship: With Dirty Rat and to an extent with Pigface, Rotgut, and even Lord Fear.

* DoomyDoomsOfDoom: Rick starts saying everyone is doomed after Kilobyte is let loose.
* EvilGenius: Considers himself one based on his genius and evil schemes to use Kilobyte to let the world know of his brilliance.
* GameMaster: The video game variety. The creator of the game itself, and the program that allows the characters to come to life. He plots behind-the-scenes, controlling Lord Fear and then Kilobyte. However, things have not been going according to plan, such as Lady Illusion's romance with Ace and Lord Fear's repeated defeats. Rick then creates Kilobyte to further his agenda, but it backfires on him spectacularly when he gets too big for his boots.
* GreaterScopeVillain: Revealed to be TheChessmaster of the whole story, intending on using Kilobyte to win the game and take over the world. He quietly operates from his backroom in his store where he hides a giant mainframe containing the Sixth Dimension.
* HeelFaceTurn: Teams up with Mark and Chuck as soon as Kilobyte turns traitor.
* LifesWorkRuined: Doubles as ICouldaBeenAContender. Rick invented a computer program which could bring video game characters to life in the real world. Instead of revolutionising gaming and technology, Rick for whatever reason was mocked and fired. He managed to encode his program into one game beforehand, which is owned by Mark.
* MadScientist: More like Mad Programmer.
* TheManBehindTheMan: He is technically responsible for Kilobyte and Lord Fear's creation.
* MasterComputer: Rick has a mainframe hidden in the backroom of his store.
* MoreThanMeetsTheEye: Looks like a rather grouchy computer repairman, but is really a criminal genius who has the power of a god and designed the software that could bring the game characters to life.
* MysteriousEmployer: Subverted. He is shown but Chuck finds him mysterious.
* TheReveal: Rick's true identity was [[ForegoneConclusion somewhat obvious]] from the get-go but the trope is still pulled anyway.
* SmallNameBigEgo: He helped design the video game, but also a made a program that could bring them to life in the real world for a more interactive experience. No one believed him and he was fired. Fuelled by revenge and a bruised ego, Rick plots to use Kilobyte to conquer the world as payment for his dismissal.
* ShoutOut: Rick's backroom is called [[Franchise/{{Superman}} The Fortress of Solitude]].
* TechnoWizard: A skilled hacker and programmer, owns a huge mainframe, and created a program which can create life.
* WhatYouAreInTheDark: Rick hides his true self behind closed doors.

Fiona is more down-to-earth and likes to remind her family they are still British, and often cooks British food and loves garden gnomes. She is a real estate agent.

* InvisibleToAdults: Ace, Lord Fear and co. are never seen by Simon and Fiona - whilst pretty much every other adult character in the show encounters one or more of the video game characters.
* LethalChef: Simon displays his inability to cook, turning sausages into charcoal. Ahsley wisely avoids eating them.
* OurGnomesAreWeirder: Fiona loves garden gnomes. Ace not so much. The video game has deadly garden gnomes as enemies, which Ace gains his hatred from and he deliberately destroys multiple garden gnomes.
