The heroes of the show, the Lightning Knights are interdimensional superheroes/policemen who guard the Sixth Dimension from evil. Their authority spreads to other worlds when Ace Lightning chases Lord Fear to Earth. While only five members are introduced in the series, the show's creator revealed that there were more Lightning Knights, some of which are stronger than Ace and Random Virus combined.
The titular character and main protagonist alongside his sidekick Mark. A superhero Lightning Knight from the Sixth Dimension, Ace Lightning follows Lord Fear and his gang to the real world to capture the villains and restore the broken Amulet of Zoar. However, his time on Earth alters his original programming, and dates Lady Illusion, as well as gaining unstable human emotions.
Dating Catwoman: Ace dates Lady Illusion, although it is in secret for most of the first season. It is hinted from a line by Ace to Lady Illusion ("Still wanna brag about you power, playmate?") that the two characters spent time together as children.
Dumb Blonde: Subverted. Ash has his moments of stupidity.
Fish out of Water: 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 an encounter with living gnomes in the Sixth Dimension seen in the video game. Ace again fits this trope when he experiences his new emotions in the second season.
Flight: Ace can propel himself to fly at the speed of electricity.
Lightning Gun: Ace has two "wrist cannons" which can fire his electrical attacks.
The Nicknamer: He often gives nicknames to the villains, although this is shared with Lord Fear who gives nicknames to his own minions.
Paper-Thin Disguise: Happens several times. He dresses as a hooded janitor to save Mark; dresses as a masked police officer when Googler steals his powers; and as a motorcyclist wearing a helmet during his stakeout with Mark to keep an eye on Samantha.
Playing with Fire: Subverted. In the second season, Ace gains an ability called "Ring of Flame" which projects small rings of fire.
Running Gag: 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 season one when he successfuly evades breaking Mark's window again.
Shock and Awe: 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.
What the Hell, Hero?: 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.
The viewpoint character of the series (most of the time) and the Narrator. Mark is a teenage British kid who moves to Conestoga Hills, USA and is at first a Fish out of Water. His house is struck by lightning and characters from his favourite video game come to life, and is enlisted by Ace to be his sidekick, his life now falling between being a superhero and a normal kid.
Apocalyptic Log: Mark talks to his friend Pete via a webcam usually in every episode.
Bad Ass: At first he hides during early battles but then confronts Random Virus repeatedly, fights Zip and Snip, and Pigface, and Fred separately with a metal bar, and is even willing to fight Lord Fear.
Big "NO!": In the final episode where Mark thinks Ace as been wounded by Lord Fear, but it is revealed to be Lady Illusion in disguise.
Disguised in Drag: Played with hilarious results in the ninth episode. Mark dresses up as a teenage American girl to keep an eye on Samantha - encountering Chuck, his parents and Wayne who ends falling in love with his female counterpart.
Refusal of the Call: Mark repeatedly refuses to become a superhero, at one point quitting the superhero business all together after Sparx insults his abilities as one.
Reluctant Warrior: Mark keeps saying throughout the series that he is not a hero or a Lightning Knight. He eventually accepts his role.
Sadistic Choice: 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.
Wake Up, Go to School, Save the World: That's pretty must the jist of this show - with video game characters. Mark even appears to acknowledge this in Episode 2 - "First save the world, then be home in time for dinner."
Mark's nerdy, jolly best friend who is completely Genre Savvy around Ace Lightning. He is often bullied, but is quite brainy and later becomes the tech guy for the Lightning Knights.
Vomit Chain Reaction: Chuck has a nasty habit of being sick. In the first episode he comments how he threw up on a bus and it caused pandemonium. This trope really comes into play in Episode 4 where Chuck hurls after finding a pea in his dessert, causing other people in the room to throw up and flee the cafeteria.
Ace's former sidekick, Sparx is a Fiery RedheadAction Girl whose cocky attitude can often get her into scrapes with the villains. She is a master gymnast and swordswoman. She flies using a hovercraft called the Lightning Flash.
A 35-year old Lightning Knight, Random Virus was mortally wounded by an accident long ago and is now a Cyborg, but his mental state has created a Split Personality between a good and an evil side which interswitch. He lives in Conestoga Hills' junkyard to avoid harming others.
Affably Evil: Random's evil side maybe a psychotic Blood Knight but he only attacks those who are cowards in nature. He goes to attack Mark but backs down upon realising that while he is terrified, he is not a coward.
Artificial Limbs: 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.
Screw This, I'm Outta Here!: In the second season, Random willingly comes to Ace's assistance fighting Lord Fear, unaware Ace has just suffered from Lady Illusion's Emotion Bomb. 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.
Split Personality: 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.
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 an Amusement Park of Doom. Lord Fear, The Big Bad of the series, leads the carnival with the plan to conquer the world using the Amulet of Zoar's powers. The villains can suffer Disney Villain Deaths, morphing into locations around the carnival to rest and recover until their next appearance. The carnival is later taken over by Kilobyte.
Ace's arch nemesis, an undead Evil Sorcerer hellbent on taking over the world. Crippled accidentally by Ace, Lord Fear seeks revenge on him. He now walks with a permanant limp, but is a masterful strategist in his plans to destroy Ace and capture the pieces of the Amulet.
Affably Evil: Despite being the Big Bad, Lord Fear is very polite, intelligent and has hobbies like playing the pipe organ and miniature golf.
All Part of the Show: Lord Fear tries to gain the final piece of the Amulet during the school's performance of The Phantom of the Opera, 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.
Bad Boss: He will abuse and insult his minions when they fail him.
Badass Biker: Lord Fear becomes even more awesome when he gets the Doom Wagon, a rocket-powered motorcycle-hovercraft with a chainsaw on the front.
Badass Boast: "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!"
Lord Fear's sidekick, weapon, walking stick and advisor all in one. He is a winged talking frog who perches on the end of Lord Fear's staff. He is loyal to Lord Fear, but very pompous and rude to everyone else. He can fire laser blasts from the glass orb he carries.
You Don't Look Like You: Staff Head got a re-design in the second season, appearing more frog-like and can actually move around on the staff, and can fall right off.
Initially The Dark Chick, Lady Illusion is a shapeshifting dark elf who originally is programmed to be Lord Fear's mistress. However, she ends up falling in love with Ace and the two go into a Dating Catwoman situation for most of the series. Her loyalties to Ace and Lord Fear are tested throughout the series.
Action Girl: Despite being Lord Fear's lackey in the second season, Lady Illusion is more than capable of taking care of herself.
The Big Bad of Season 2, Kilobyte is known as the Cyber Stalker. Created by The Master Programmer to exact his revenge on the Lightning Knights, Kilobyte is a merciless and downrighy creepy villain who thinks like a hunter, seeing Ace as prey and plans to destroy him slowly and painfully.

He can create bombs like Lady Illusion's. Dirty Rat usually follows whoever is the strongest person in the carnival, interswitching between Lord Fear and Kilobyte's leadership. He morphs into a gargoyle.
Affably Evil: Dirty Rat can be a decent guy when he's not being a coward or a jerk.
The Starscream: In Episode 25, Dirty Rat starts a rebellion against Lord Fear but it ends when Lord Fear gets his hands on all of the pieces of the Amulet. Lord Fear offers Dirty Rat the chance to rejoin him or die, and the rat joins him without any punishment.

Googler has his own minions, in the shape of a pair of evil talking sock puppets named Zip and Snip. The two may be an extension of Googler's mind, as they share his love for madness. The two can remove Ace's superpowers, bite right through materials, and even turn Ace into a zombie once.
An undeadcowboy introduced in Season 2. Rotgut is Laughably Evil and useless.

Mark's British parents. Both are oblivious to their son's double life as a superhero, and blame Ace's breakages on shoddy American craftsmanship. Simon is 45 years old, an accountant and tries to adapt to American life, speaking American catchphrases and tries out various gadgets with hilarious outcomes. 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.
Adults Are Useless: They are oblivious to their son's life as a superhero, and never directly encounter the video game characters. The closest they came to that was meeting Ace who was dressed as a motorcyclist at the time.
Mark actually tells them the truth in the fifth episode but they just assume he is acting his age and being imaginative.
Berserk Button: Do NOT mess with Fiona's gnomes or her garden. Simon's berserk button is when someone insults his son.
Bob from Accounting: Simon mentions numerous fellow accountants but only himself and Bud Ratburn are shown onscreen.
D.I.Y. Disaster: Simon often tries out new gadgets, some of which are broken by Ace beforehand. Simon also tries out a rideable lawnmower which he demolishes Fiona's garden with.
I Am Very British: Fiona tries to never forget her British origins. She keeps garden gnomes in the "proper English garden", and cooks British food for Mark's Halloween party.
Invisible to Adults: 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.
Lethal Chef: Simon displays his inability to cook, turning sausages into charcoal. Ahsley wisely avoids eating them.
Our Gnomes Are Weirder: 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.
Mark's little cousin, Ashley is the third human to learn of Ace and co. She promises to keep it a secret and becomes a recurring character. She has a pet hamster named Chika, which Ace finds adorable, and in her first episodes has a thing for cuddly toys. Ashley and Chuck get on like a house on fire, and enjoy horror films.
Little Miss Badass: Ashley is pretty awesome in her own right. She lays a trap for the Tooth Fairy, which is accidentally set off by Chuck and used to scare off the villains.
Chuck's girlfriend and Wayne's cousin. A nerdy girl who is just a fan of Ace Lightning as much as Chuck is, the two start dating. Jessica wants best out of their relationship, which makes it tricky after Chuck finds out about Ace.
Beautiful All Along: In Episode 26, Jessica arrives late for the school prom and removes her hairband and glasses to reveal her true beauty.
Blackmail: Jessica pulls this off on Wayne to let her spend time with Chuck, revealing his mum called him "Boogerbox" when he ate the contents of his nose.
The middle-aged dinner lady at the middle school, Mrs. Kutcher is a bit of a disgruntled employee believing no one appreciates her cooking aside from Chuck. She mostly provides comic relief, but acts motherly towards Chuck and occasionally Mark.
