“It was ONE lousy C, mom, in gym. It's not even a subject, it's like some guy's name.”
Lee Ping, is the main protagonist of the series, and a tenth grader attending A Nigma High. On his first day of tenth grade, he was framed for pulling off a "mind blowingly epic prank" and thus received one full year of detention . Lee belongs to none of the cliques in the school and as a result no one (except his closest friends) would care if he was gone, making him the prime target for the whole conspiracy.
Prior to seriesEdit
Lee was born in Korea and moved to Canada at a young age.
Lee has been best friends with Holger and Camillio for a long time, knowing Cam since before he was ten and knowing Holger for a shorter but still substantial amount of time. Also Lee has been taught how to fight by his father while his tattoo is strongly implied to have mystical connections to The Pyramid. Lee can't even remember getting it assuming it was some kind of birthmark.
At the age of ten Lee had to switch schools, making him the "new kid" to everyone. He invited Cam and the three future members of The Outcasts clique to his 10th birthday party, the latter group because they were still popular at the time. The famed hypnotist The Amazing Finnwich was hired as entertainment, hypnotizing Camillio into thinking he was a chicken, a ballerina and a monkey.
Lee has been friends with Tina Kwee since 5th Grade and has secretly had a crush on her for just as long. He has always had above average intelligence, his mother once forced him to join the "Mathletes" and he has gotten A's every year in all his classes, except gym. Also, he took violin classes for a period of time starting when he was ten.
Lee appears to be a subject of the research at the secret underground research labs under A Nigma High, where there is a file containing a large amount of information on him dating back to when he was a baby. Why he is being monitored remains a mystery.
On the first day of tenth grade Lee is framed for The Prank while he is in the bathroom, and receives one full year of detention and is grounded for one full year as punishment. Since then he has spent every day trying to find out who set him up and why.
He has become one of the most popular students in school as a result of The Prank, but he neither wants to nor has the time to enjoy the popularity. Lee has found friends including but not limited to: the Jocks, the Dudes of Darkness, the Skaters and the techno-savie bully Biffy Goldstien. Lee has also made enemies, notably the Down with Lee Club and Principal General Barrage, as a Detentionaire, but continues to try and clear his name despite their opposition.
Lee discovered the email address of the person who set him up, Radcircles@Anigmahigh.ca, the former account of ex-Principal Wurst. He deduced that Wurst did not do the prank based on the fact that he hasn't seen him around the school since he disappeared one year earlier. Lee also discovered a series of underground tunnels beneath the school, which appear to be abandoned subway tunnels renovated into a massive underground lab.
Apparently the focus of research of the lab is The Prank Song which has the ability to brainwash people. Thanks to Chaz's stolen news footage of day one Lee is led to believe that he has discovered who Radcircles really is: seeing Camillio switch his bag on the news footage of the prank who subsequently destroys the footage and whom Holger has already found further evidence of Camillio's involvement he is led to believe he and Radcircles are the same.
Lee learned that his friend Camillio had been brainwashed during the Prank in order to set him up as a red herring and thus began the process of hunting down the one who brainwashed him, The Amazing Finnwich. Lee was able to find him eventually, though mostly out of luck rather then his investigation, and learned that he had nothing to do with the Prank. Lee's popularity takes some hits in this season due to the actions of Ruby Kwee.
First, Ruby takes the credit for the Prank, leading the student body to believe that Lee took the credit for the prank for his own gain. Second, after Ruby admitted she didn't do the prank the student body believes that Lee framed her just to get out of detention. Despite this Lee has also proven himself to his classmates: during the berserk cleaner incident Lee risked his life to defend his classmates, lead them to safety and finally defeat the Cleaners.
Unfortunately as a direct consequence of his investigation Lee has been expelled from school by Inspector Blompkins. Lee has also discovered the true identity of Radcircles, the school's IT technician Lynch Webber and his boss Vice Principal Victoria both of whom has been using the school and it's students as lab rats to perfect the Prank song in a bid for world domination.
Lee was able to stop Victoria at the School's dance by proving to Victoria's colleagues in The Council that the song is in-effective for world domination: if the small minority immune to the brainwashing process can snap out their peers from the trance then the song, while still retaining potential, is utterly useless. With the conspiracy seemingly resolved Lee is finally able to ask his long time crush out Tina Kwee.
Lee is narrowly able to avoid being shipped off to Alaska by his mother thanks to the intervention of a unknown benefactor, whom instructs the new principal, Blompkins, to un-expel Lee. Also thanks to Lee's actions Blompkins is fired as principal, reinstating Barrage in the process. During The annual fencing match it's discovered that Lee is deeply connected to a mysterious/mystical pyramid underneath the school.
Also thanks to the Outcasts Lee discovers a book detailing information about the Tazelwurms and the Pyramid, unfortunately it's written in some kind of ancient language. As a direct consequence of his investigations, Lee's family is put under threat by the council. Lee later Reunites with Finnwich and Lynch and learns that both they and the Council are after the Pyramid.
Although the Pyramid is finally opened Lee cannot make sense of the strange writing even with Finnwich's cipher. Having finally learned the information he's been seeking for well over a hundred years Finnwich destroys the Pyramid less it's secrets fall into the hands of the council. Finnwich is captured and sent off to Coral Grove and Lee attempts a rescue mission alongside Biffy and Holger.
The mission fails and instead Lee ends up in the fight of his life against the mysterious Serpent. Although the clearly superior fighter nearly kills Lee he is able to both save himself and push the fight into his favor using the Serpent's allergy to fish to partially blind him, followed up by escape with his friends. Lee was finally able to admit his feelings for his long time crush Tina Kwee.
Sadly a tearful Tina was not able to reciprocate Lee's feelings less she compromise her new-found friendship with Jenny Jerkins.

Disguises & AliasesEdit
- Number 77 - During football try-outs Lee donned the persona of a rather skilled football player known to Barrage only as Number 77, whom was able to outwit Barrage's many tests by combining IT support, intellect, and sheer determination..
- El Beardo - In order to hide from Barrage during auditions for the school play Lee dressed up as Alexander Nigma. Barrage, not realizing it was Lee, asked him to read some lines from the script. Barrage found Lee's awkward performance fitting for the play, despite the fact that he's really not a good actor, and cast him as Alexander.
- Unnamed DOD member - During the yearly battle of the bands competition Lee's friends disguised him as a British styled rocker which allowed him to participate in the battle of the bands alongside the Dudes of Darkness on the violin.
- Brad Von Chillstein - When Brad was making moves on Greta Von Hoffman and Brandy Silver Lee agreed to take his place during the annual fencing match in exchange for him to stop, using Brad's signature flame printed fencing uniform to complete the disguse.
- Manifestum - The Amazing Finnwich's nickname for Lee. Finnwich based the name on the fact that Lee cannot be hypnotized, as a prophecy Finnwich was told of by his master names such a individual Manifestum. However Finnwich may have been lying about where he got the name, as it's shown that "Manifestum" is connected to The Pyramid in the season 3 finale. Even despite the fact that Lee has made it clear that he has no wish to kill Finnwich as stated in the prophecy Finnwich still calls him by this nickname.
Lee is a loyal friend who is confident in his abilities. He will risk his safety to help his friends knowing that they would do the same for him. He's willing to put himself in danger if he believes that the risks are worth the rewards and is usually right in his assessment. As noted by his friends and family, Lee is usually in a bad mood as a result of his determination to clear his name, and the stress it causes.
Lee can also be very persuasive, verging on manipulative at times. He manipulated Holger into taking off Cam's shoes to match shoes prints,  stopped Steve from ratting him out,  manipulated jocks into taking his place as pumps to the school's equipment,  and even tricked Barrage into breaking the prank song effect. Lee and Biffy have some kind of effect where they don't get hypnotized by the prank song Lynch (Radcircles) plays.
Lee Ping is well rounded in terms of his abilities, he is highly intelligent and capable of getting good grades, perceptive enough to figure out the clues to the prank, open-minded enough to not turn down a clue, and (despite only getting a C in gym the prior year) physically fit enough to match the football team in try-outs. He was the only new player left after Barrage's assault meant to test his football team. 
In Blitzkrieg Bop'd Lee shows he is agile enough with a skateboard to skid across a pool and land on the other side, and durable enough to emerge from this trick unharmed. Also Lee has been trained in armed and unarmed combat by his father, which Lee has demonstrated against Lynch, the Cleaners, and the yearly fencing match and is believed to have a mystical connection to the pyramid underneath the school.
Lee is immune to the prank song and other forms of hypnotism due to a genetic oddity. However it is unknown from where he got this trait because in "The Dance Part 2" Lee's mom is hypnotized and in "Finding Finnwich" his father claims to be affected by Finnwich's hypnotism, making him not immune if he was being truthful. Lee may have inherited this trait through a resesive gene, or from enviromental factors, or a "simple" mutation.
“Lee Ping is that mysterious cool guy who seems to breeze through school. But he's no overachiever! And he certainly has no interest in being in any clique. He's his own guy and fiercely loyal to the same two friends he's had for years. All that changes, though, when he's framed for the biggest prank in high school history. Now he needs to apply all of his numerous mental and physical talents to fully navigate every aspect of school life and beyond as "the Detentionaire!"”
