Ace Lightning/Characters

The Lightning Knights
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.

Ace Lightning
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.
 * The Ace
 * Badass: Particularly when he is struck by lightning in Episode 2.
 * Big Damn Heroes: Along with Sparx and Random Virus.
 * Brainwashed and Crazy: In Episode 13, Ace is turned into a zombie by Googler's sockpuppets. He goes a bit loopy when he first gets his unstable emotions in the second season.
 * Brought Down to Normal: In Episode 7, Ace's superpowers are removed by Zip and Snip, and he has to walk around disguised as a masked police officer.
 * Catch Phrase: The code of the Lightning Knights: "Do right and fear not."
 * Characterization Marches On: Ace starts off as a wisecracking and heroic superhero, but over time he becomes more human during his experiences in the real world.
 * In Season 2,
 * Chaste Hero: Ace admits he's never flirted before. And he's a 32-year old. However, this can be justified since he is a video game character and his programming likely didn't involve romance.
 * 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.
 * Does Not Know His Own Strength: Former Trope Namer. Ace's superhuman strength causes him to unintentionally trash Mark's house throughout the first season.
 * Fish Out of Water: Ace is bamboozled by Earth, often fiddling with technology in Mark's house and destroying it. He also gates a hatred for garden gnomes, although this stems from an encounter with living gnomes in the Sixth Dimension. Ace again fits this trope when he experiences his new emotions in the second season.
 * Flight
 * Glass Cannon: Becomes this when he is low on power.
 * The Hero
 * Heroic BSOD: 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 First Kiss.
 * 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.
 * Ring of 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.
 * 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.
 * Super Strength
 * Superheroes Wear Capes: Averted. Ace comments he hang up his cape if he had one.
 * Welcome to The Real World: Ace has a hard time getting used to Earth.
 * 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

Mark Hollander
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.
 * Badass: 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.

 * Reluctant Warrior: Mark keeps saying throughout the series that he is not a hero or a Lightning Knight.
 * 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.
 * Sidekick
 * Supporting Protagonist: Subverted. At times he goes from supporting protagonist to main protagonist.
 * Ten Minute Retirement: Mark quits the superhero business for half an episode.

Chuck Mugel
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.
