PS238

• Atlas came to Earth from the planet Argos, crashed in Iowa and was raised by an old farmer who had no children of his own. Atlas is vulnerable to Argonite, married a reporter, and at one point, had a pet super dog named Argo. The Superman parallels are obvious: Krypton/Argo, Kryptonite/Argonite, etc. The biggest difference is that Argos, unlike Krypton, has not been destroyed. Atlas thought most of his life that it had been, but in issue 42 he learns this was a deception. His Argonian name is Ul-Ron, and his Earth civilian name is Ron Peterson, Senior.
• The Revenant is, as stated before, much like Batman; he has no superpowers and instead relies on detective skills, gadgets, wealth, intimidation, physical and mental prowess in his war on crime. He is quoted as saying, "Sometimes I think access to cash is the greatest superpower of all." The Revenant is a character from a Michael Stackpole short story, “Peer Review”. Mr. Stackpole donated the Revenant to the PS238 project. Moon Shadow, Cecil Holmes, and The Flea are disciples and sidekicks of the Revenant.
• Several heroes are members of the team known as the Nuclear Family:
  • First Strike, team leader.
  • The Atomic Pile.
  • Mental Nucleus, mad inventor.
  • Plutonium Saber.

The faculty of PS238 includes:

• Alfred Cranston, the school principal, with telekinetic and telepathic powers which he used to assist him in becoming president, though he claims only to have done it to be able to help others. When his mental powers were discovered, he faced a revolution until the Union of Justice intervened. Part of the negotiation for his peaceful leaving of office included starting PS238, with him as principal, to teach young meta-humans how to use their powers responsibly to avoid similar issues in the future. He also agreed to wear a headband which contained his mental powers, but the headband was eventually destroyed in an accident during a later issue.
• Herschel Clay, who teaches shop class and used to fight crime as the armored hero Mantium.
• The robotic Doctor Positron.
• The mystic Vashti Imperia, code-named "Spell Syrin."
• Coach Rockslide, with powers and appearance similar to Marvel Comics' character Benjamin Grimm (aka The Thing).
• Cristina Kyle (based on Aaron Williams' wife, Cristi[2]), whose code name as a superhero was "Micro Might." Superpower is to shrink in size, but increase in strength and durability. She was the only faculty member who had experience as a teacher prior to starting the school.
• Alloy, who is similar to the Marvel Comics' X-Men character Colossus in general appearance, but seems to have the power to alter the atomic composition of metals on the periodic table - in one issue he is noted as changing the wall composition of PS238 into gold to make it easier for Rockslide to tear apart. Alloy also has a great love of Star Trek, as is shown in his zeal when Wil Wheaton shows up for a career fair at the school.
• Dr. Newby, a skilled professional MD with metahuman Healer abilities. Her patients include Murphy, Principal Cranston, Tyler, and Toby.

Of these, only Principal Cranston and Dr. Newby were not members of the Union of Justice. Ms. Kyle was the only faculty member who had any teaching experience before the school was founded; the others got a simulated crash course in teaching via one of Herschel's machines.

Other than Tyler Marlocke, all the children at PS238 have superpowers:

• Victor Von Fogg (a nod to Victor Von Doom). He is the son of would-be world conqueror Doctor Philippe Von Fogg, whose name and face are suspiciously similar to those of cartoonist Phil Foglio, friend and colleague of Aaron Williams. The Von Fogg family lives in a huge armored Zeppelin (perhaps a reference to Castle Wulfenbach, a city-sized airship featured in the ongoing webcomic Girl Genius by Phil and Kaja Foglio).
• The Emerald Gauntlet (who has powers similar to Green Lantern). These two have a particularly contentious relationship as The Emerald Gauntlet (senior), is the parole officer for Victor's father. The Junior Gauntlet's real name is Kevin. He is Moon Shadow's biggest fan.
• Ambriel, code-named Guardian Angel. Some mysterious force protects her from hazards and annoyances, from rain to other metahumans. She has a tendency to collect equipment from her adventures, to compensate for the passive nature of her powers. Most notably she possess a baseball bat which strikes with explosive force, built by a baseball themed supervillain.
• A blue Hulk-like child named Bernard.
• Murphy, a child version of Dream (a.k.a. Morpheus) from Neil Gaiman's The Sandman.
• Zodon, a genius gadgeteer who has a "Barry Ween" chip (replacing profanity with such terms as "Finland!" or "Gurgling piece of pot roast!", and larger strings of profanity with Rodgers and Hammerstein show tunes), a rivalry with Von Fogg over who will be the greater supervillain and a very vocal distaste for Tyler (centering on his lack of powers - and the fact that Tyler, of normal intellect, always outmaneuvers supergenius Zodon). Bald, abrasive and sarcastic, Zodon appears to be an underage version of MODOK. He also has a lot in common with Gizmo, a nasty young techno-villain in Teen Titans.
• Malphast. Similar to an entity in Preacher. He comes from the Realm of Order and Chaos. His best friends are Tyler Marlocke and Cecil Holmes.
• Tom Davison, a time-traveler who resembles the Fourth Doctor, only a lot younger. Has a lot of affection and respect for Tyler. His name might be derived from Tom Baker and Peter Davison, the actors who portrayed the Fourth and Fifth Doctors.
• American Eagle and USA Patriot Act, respectively Democrat and Republican patriotic heroes. Each one aspires to be the successor to Freedom Fighter, the equivalent of Captain America.
• Alejandro Torres code-named The Flea. A junior version of Spider-Man, he aims pranks and zingers at the villains he fights.
• Julie code-named "84," The 84th person with the standard FISS (flight, invulnerability, speed, strength) powers. Like Atlas, she is affected by Argonite. She is polite, humble, and more reserved than many of the other heroes. She chose not to allow the fact that other superheroes tend to look down on those with FISS powers bother her, instead choosing her number as a code name to show she is proud of what she is. This eventually resulted in her unwittingly becoming an online celebrity and rallying call to other FISS, a status she clearly doesn't want but is trying her best to handle gracefully. She is friends with both Moon Shadow and Tyler but does not realize they are really the same person. In 2015 Julie had a crucial encounter with the legendary Russian witch Baba Yaga.
• Poly Mer, a girl with powers like Plastic Man and Mister Fantastic. Julie's best friend.
• Angie, a mad inventor and Techie. Good friends with Prospero and Tyler. She is the only one capable of understand Prospero, though she isn't able to explain how.
• Prospero, an alien with an undecipherable language. Disguised as an African exchange student.
• Suzi Fusion, a fearless little girl with superpowers of radioactivity.
• Toby Marlocke, also known as Ultimate Powers and Junior Powers. Basically, a clone of Tyler, but with DNA also from various superheroes. He considers himself Tyler's twin brother, and Tyler's parents have accepted him as such. Angie, Victor, the Cherub and the Imp all had a hand in creating Toby. His powers are immense and allow a large variety of abilities, however, they must be balanced out by some 'opposite' side effect. He desires a relationship as a brother with Tyler, but Tyler's own feelings of resentment due to Toby replacing him as a better son in his parents' eyes have prevented him from accepting Toby's attempts at bonding. Besides superpowers, there is another difference between the "twins": Tyler is left-handed, and Toby is right-handed.
• Franklin, a speedster. In looks, personality and powers, seems to be a younger version of Bart Allen, aka Impulse.
• Vern, an extremely powerful healer. He was able to resurrect Ambriel.

Excelsior School, located 3 miles above PS238, has provided several characters, most notably:

• Cecil Holmes, conspiracy buff, best friend of Tyler Marlocke, disciple of the Revenant, good pals with Alejandro Torres the Flea and with Malphast. He has the ability to detect those with superpowers, and originally thought they were aliens. Oddly enough, he sensed Ron Peterson who is the son of the alien Atlas.
• Satori Deacon, a girl who can see ghosts and spirits, and communicate with them.

The rival Praetorian school, headed by the Cyborg supervillain known as The Headmaster, includes in its student body:

• Charles Brigman, a teleporting bully, extortionist, kidnapper, terrorist, and thief.
• Ron Peterson, son of Atlas and of Lisa Larson, a famous journalist. Previously known as "Captain Clarinet," Ron has the new code name "Argonaut." His greatest weakness is not Argonite, but his lack of self-confidence. During a trip to the planet Argon, Ron was de-powered, and subsequently he was transferred from Praetorian to Excelsior. Being a normal boy in an ordinary school made him a much happier boy.
• Alexandria Von Fogg, Victor's sister.

The Realm of Order and Chaos, home of Malphast, includes some recurrent characters:

• Balagan, Lord of Chaos. His name means "chaos, confusion, disorder, mess," in modern Hebrew.
• The Determinant, Ruler of Order.
• A Great Lady Demon of Chaos, mother of Malphast.
• A General of Seraphim, Warrior of Order, father of Malphast.
• The Cherub, agent of Order.
• The Imp, agent of Chaos.
