[2] As a character, he is socially inept and frequently depressed or morose; in addition, he is a fairly skilled artist who refuses to believe in his own talent—an exaggerated parallel of Gallagher himself.
Piro has stated that without his glasses he cannot see especially well at any significant distance, although he did not wear them (as of Chapter 7-9) because Largo sat on and broken them, he coped with the situation quite well.
Lately, Piro received both a new pair of glasses and a hair cut in Chapter 10,[4] which makes him resemble the illustrated real life Fred more closely.
He is technically gifted, though in bizarre ways: he often uses beer as a CPU coolant, and he often works on computer hardware in boxers (or completely nude) to avoid electrostatic discharge.
Conversely, Largo's obsession with gaming has led him to develop a number of remarkably profound concepts which guide his life, such as when one "plays" with others, they should support each other, not just "camp" and "snipe".
He is extremely well liked by the students, and though Junpei has had to drag him to his job at various times, Largo is still a very respected and well-liked teacher, presumably due to his unorthodox style of teaching, which involves a great deal of shouting.
In the current story arc, he again has fought the undead horde, but this time both Boo and Sonoda Yuki were by his side to help assist in the battle.
Erika was deeply hurt, and that event, combined with exposure to swarms of fanboys and possibly her periodic work as a "booth-babe" at fan conventions, has caused her to adopt a rather negative outlook on men, herself, and people in general.
She is an aspiring voice actress who sometimes finds herself too shy or insecure to take on roles, but harbors beliefs on matters such as emotion and self-confidence with extreme conviction.
Kimiko has landed the role of Kannazuki Kotone (神無月 琴音) in the fictional dating sim Sight, and is earning herself an army of followers to rival even Erika's due to her rant on "Mumu-chan's" radio show, where she came to the defense of fanboys after being angered by the hosts' derisive comments about them.
Ping (ピングちん Pingu-chan) is a robotic PS2 accessory, a non-H (non-hentai; platonic love only) test model of the new Sony-EDS (Emotional Doll System) that fell into Tsubasa's hands somehow.
When enraged, she has been known to use her incredible strength to pull telephone poles out of the ground to use as weapons, and at one point manages to hurl a gigantic turtle monster through the top of a skyscraper.
Her systems have displayed the ability to change her physical traits, including hair color (from gray to pink to blue-green and, most recently, to black) and bust size.
Ping, like Junpei, appeared in an issue of Applegeeks,[16] in which the main character explained his stressful situation (ironically, involving a robot girl) to her.
Miho abused a hidden statistic in the game in order to control a large number of player characters, befriending and betraying Piro and Largo.
The events of the November 2006 strips put for the first time boundaries for these speculations, showing unambiguously that Miho is indeed capable of superhuman feats: she has been able to evade almost effortlessly both projectile and energy weapons used against her by Ed.
Largo was the first person Miho met in the comic (after he opened the Cave of Evil, possibly suggesting that she was either trapped in it or was in some way helped by its opening), he is constantly following and challenging her, and she indirectly set him up with his job as "Great Teacher Largo" — he was attempting to follow her in "disguise" when the principal found him, assuming from the English conversation he was having that he was the new English teacher.
"[20] He had Junpei take her to the school infirmary (from which she was sent to a hospital), and thus may be indirectly responsible for saving her life — she was presenting symptoms of the mid-stages of shock.
Once, she advised Piro to be pessimistic and not to waste his time trying to build a relationship with Kimiko; later she cheered him on, but also encouraged him to embrace his patheticness before she was promptly yanked away by the real Seraphim.
Seraphim is modeled after Sarah Wooden, Gallagher's wife (girlfriend when Megatokyo began), who has a penchant for fine clothes and loves cats.
In one strip, Boo showed up at the display booth of BioWare, the company responsible for Baldur's Gate series, and unsuccessfully tried to get his old job back.
Largo, being unsurpassable in all matters electronic, easily wins the contest by defeating Junpei in a match on the Mortal Kombat arcade game.
However, this apprenticeship seems to consist largely of Junpei bailing Largo out of trouble, such as getting him out of jail, and fetching him when he forgets about the classes he teaches at Shiritsu Daitou.
Yuki later catches Ping being harassed by jealous schoolmates and tries to tell them to stop (this does little good, however, since the girls have no respect for underclassmen and ignore her more or less).
However, after Sega leaves the console business, he seeks to acquire Hayasaka Erika (due to her power to influence the masses) as an asset for his company.
Later, during an attempt of Ed's to snipe Ping with an excessively large and powerful weapon, he is vaporized by an orbital laser strike and subsequently regrown in a growth tank from residual dust left behind after the incident, bearing yet another new face as a consequence.
However, he ultimately overcomes this setback and finally defeats Miho at the end of the Chapter 9, (apparently) killing her with a fitting yet excessive laser barrage.
Strange raver-esque person who appears occasionally - usually when Largo is playing arcade games - and gives advice in L33t, which is invariably translated into erudite language (i.e. "1'm4 0wnz0r j00" becomes "I shall defeat thee").
He owes Largo a debt of gratitude for saving his life[38] He has an apparent heart or blood condition that requires him to take medication, and can send him into state of collapse if unattended.
He acquired Ping through unclear means in chapter 0; he said he had invested in the project, but Ed's actions would seem to suggest he wasn't supposed to take her.
