Super Slang: Supers
Being "super" is more than just having powers, it's being part of a culture with its own jargon. Not all super-slang terms are in equally wide use; some, such as "cape" and "mask" go all the way back to the 1920's; others, such as "toyboy", are of much more recent vintage, and popular only with the younger generation.
Super: Short for "superhuman", this is the generic term for anyone with powers. More widely, it refers to anyone who can hold their own in a super-combat, even if it's only by using gadgets. Note that there is a distinction between being a super (having powers) and being part of the Super subculture. (When capitalized, it refers to the culture.)
Cape: While this can be used as a generic term for supers, it definitely carries a "good guy" flavor. Capes are heroes, fighting crime usually openly with the police.
Mask: Again, this can sometimes be a generic term, but it carries a darker, more sinister edge. Masks aren't necessarily villains, though - violent anti-heroes can be called masks.
Vig: Short for "vigilante", this refers to someone who fights crime illegally. Vigs are usually also masks - it would seem strange to call them capes, unless perhaps they are squeaky-clean otherwise. Nocturne is a vig, and a hardcore vig at that. (See "hardcore", below.)
Hero: A collective term for anyone super who fights crime; it covers both capes and vigs. More of a general-society term than a Super term, though capes do often believe in being heroic. (On the other hand, as a verb 'to hero' it is quite common in Super circles.)
Villain: Supers who aren't heroes. Villains are a subset of masks, though "mask" in context often means the same as "villain". Though this term is also current in wider society, it sees some Super use too.
Slacker: A super who does not participate in the Super subculture; they neither fight crime nor commit it. Either they are trying to hide their powers, or they use their powers for some non-heroic, non-villainous purpose. Above all, they do not wear costumes or use codenames.
Half: Someone with super-powers, but not at a level or of a type to be remotely useful as a hero or villain. Halves aren't usually called slackers, whether associated with the Super subculture or not; they're basically "norms with powers".
Old-School: Refers to supers who, while they are heroes or villains, disdain to wear costumes and often avoid using the flashier Super lingo. (Costumes, and to a lesser extent codenames, came back to the fore during the Vietnam War as a way to avoid being preferentially drafted. They had been used previously by the Mystery Men, though.) There is a spectrum of old-schoolness - supers with families to protect will almost always conceal their faces. Also, it's nearly impossible to avoid having a codename these days, as the press will pin one on you if you don't have one already.
It should be noted that old-school supers have a tendency to also be hardcore (see below) - they may not buy into the unwritten Super code of not using excessive force. Golden Age heroes did not have much compunction about killing.
Bazooka is notably old-school. His only "costume" is Army fatigues with "Bazooka" where the name should be. To many supers of his generation (he was born in 1950), costumes are associated with draft-dodging.
Hardcore: The Super subculture has an unspoken agreement not to use excessive force. Heroes and villains will fight each other cheerfully, but few will try to actually kill their foes. (Deathtraps are a grudgingly accepted, traditional dodge.) Likewise, deliberately killing or maiming norms with superpowers is frowned upon even by most villains. (Though using one's powers to put norms in danger - collapsing a ceiling, for instance, to delay heroes - is, again, more acceptable.) Hurting kids, in particular, is considered so vile that even most villains will spit on you.
Hardcore heroes and villains do not abide by this tacit code. Supers with a reputation for being hardcore will often find their opponents treating them in a hardcore fashion as well - the rule being that the code doesn't apply to those who don't observe it.
Hardcore can also refer to other violations of the unspoken rules. (See "wigjob" below for an example.) These rarely call forth lethal force in response, but do "authorize" the opposition to use similar dirty tricks. For example, Enigma draining Photon's powers (as he thought) was borderline hardcore; that's why Photon felt fully justified in sniping at him invisibly, which would otherwise have been rather questionable itself. But a villain whose powers revolved entirely around draining would have been given a pass by many supers; things get complicated that way.
In Shadow-Force, Erebus was as hardcore as he could get away with while still remaining a cape. (This is sometimes called "softcore". Villains can be softcore too - Enigma arguably is.) Bazooka, while not as hardcore as Erebus, did not go to great lengths to restrain him.
Civilized: The opposite of hardcore. "We're both civilized individuals, let's just fight this out."

Types of super: (Note that some of these terms can also be applied to norms. Also, some are current in the culture at large as well - especially the terms for different kinds of mages.)
Artificer: A mage who makes artifacts. (Artifacts are the magical equivalent of super-science gadgets.) While most mages can do this, the term artificer refers to those who rely on artifacts strongly, much the way "wrenches" rely on gadgets. If someone uses artifacts without having the ability to make their own, they are a type of "toyboy", not an artificer.
Baldy: See "deadhead".
Baseline: See "deadhead".
Beast: A super with great fighting prowess, but without being a brick. Erebus was a beast.
Bigger: Anyone with growth powers. Biggers are usually bricks when grown. (Or "embiggened", as it is sometimes humorously called.) Jo-Tan was a bigger.
Blaster: See "zapper".
Brick: A super who is very strong and, crucially, also very resistant to damage.
Brute: A big, dumb brick. Often a villain.
Clotheshorse: See "suit".
Deadhead: A pejorative term used by wigjobs (q.v.), above all telepaths, for those who aren't. The more polite version is "baseline", for "baseline psionic potential". However, 'baseline' can also mean someone without any sort of psi powers; it would be odd to call a telekinetic a baseline, but perfectly appropriate (if rude) to call them a deadhead. An in-between version that gets around the limitations of "baseline" is "baldy" - ie, someone who doesn't have a wig.
Elemental: A common sort of mutant, with powers relating to a particular type of energy or substance - NOT necessarily one of the four classic elements. Enigma, along with most other people, wrongly thought Photon was a light elemental. Bolt, Photon's first foe, is a lightning elemental. Erebus could loosely be called a shadow elemental, though his powers were magical in origin. Likewise, Demeter could be called a plant elemental, but this is stretching the term somewhat.
Feral: Classically, an animalistic beast. (See "beast", above.) More widely, anyone with "naturalistic" powers. Demeter is a borderline feral - she's not enough of a combatant for the term to feel completely appropriate.
Flag: A super with a patriotic theme. Very popular in the Golden Age, though the term didn't arise until the 60's.
Godfather: A villain (almost always), whose "power" comes from commanding huge numbers of minions. These can be summoned, duplicates, or even just norms on the payroll. (The last option isn't very "super", but even a norm can be a godfather.)
Jedi: See "zapper".
Layman: A joking term for those who aren't super-geniuses. "Laymen's terms" sees a lot of use.
Mage: Generic term for wielders of magic. This encompasses wizards, sorcerers, and artificers, though usually not magical toyboys.
Muggle: See "mundane".
Mundane: A term used by mages for those who aren't. This is tolerable when used as an adjective, but elitist and insulting when used as a noun. "It's hard to explain in a mundane fashion," is fine, but "It's hard to explain to a mundane," would definitely be rude. Nowadays, "muggle" is also sometimes used, and it's definitely more insulting than "mundane".
Peeper: Someone who can spy on others from a distance with powers of any type. Precognition is sometimes called "peeping ahead", and retrocognition and object reading are likewise sometimes called "peeping back". Erebus was a peeper - he could scry through shadows and was also a retrocognitive. Though the Phantom was not technically a peeper, his invisible, astral spying largely qualified.
Though "peeping" is the generic term, "esping" and "scrying" are often used to narrow things down to psionics and magic, respectively.
'Port: Anyone who can travel between two points without crossing the intervening ones. Not always done by straightforward teleportation; dimensional travel works too. Brimstone is a 'port; Photon isn't, but his light-form is fast enough that many people probably think he is.
Shaker: "To shake" means to move something telekinetically, thus a shaker is a telekinetic. (The term comes from the association with "mover".) Teke and Mind Slayer are shakers. While shakers are usually psionic, shaking can also be done by magical spells, or even by some kinds of mutant energy powers.
The past tense of "to shake" is "shaked", not "shook". "Teke shaked me off the ground and shook me up and down."
Sorcerer: A mage who gains magical powers from summoned spirits. Enigma is a sorcerer as well as a wizard.
Speedster: A fairly common mutant power suite, involving running (or sometimes flying) at great speed.
Stalker: A super with powers slanted toward sneakiness and spying. Several Shadow-Force members, notably Erebus and the Phantom, were stalkers, as is Chameleon.
Suit: Someone who wears powered armor. If they built it themselves, they may be called a "tailored suit" (and jokingly "upper management"); if they're a complete norm without the armor, they are "toy soldiers" at best or "clotheshorses" at worst. Silver Siren is a (tailored) suit.
Tin Can: A robot, generally a mindless one. If you can have a conversation with it (Beta's close enough) it can be called a "tin man" instead.
Tin Man: See "tin can", above.
Toyboy: A "super" whose powers derive completely from gadgets. The implication is that they did not make the gadgets themselves; to call a gadgeteer a "toyboy" is quite insulting. American Eagle was a toyboy, though he was such a hero's hero that few would have called him that. Black Phantom had some mild powers apart from his gadgets but not many knew about them, so he likely would have been called a toyboy also. (Though again, nobody would have said it to his face.)
Some toyboys use magical artifacts instead of gadgets. There is, as yet, no special term for them.
Toy Soldier: See "suit".
Upper Management: See "suit".
Wigjob: Someone who specializes in "wigging" others. "To wig" is to affect someone's mind with powers - usually psionics, though others are certainly possible. (The term comes partly from "wigging out", and partly from this sequence: Telepathy -> TP -> teepee -> wigwam -> wig. "Wigwam" is occasionally heard in place of "wigjob".) The Phantom was a wigjob par excellence; Whisper is also a wigjob. Silver Siren, while she does wig people, doesn't rely on it enough to be called a wigjob.
Wigging others in a long-lasting fashion is frowned upon by the Super code. This can be called "wigging someone hardcore". (The more vulgar term for "to wig hardcore" is "to mindf*ck".) The Phantom infamously wigged Inquisitor hardcore early in his career - blocking off his powers near-permanently - but most supers would agree that Inquisitor very much had it coming. (The man was slime even by supervillain standards.)
Witch: A wigjob who affects the emotions, or who uses magic - the term is rather vague. In any case, witchery connotes a less direct, more subtle sort of wigging than the usual. "Bewitch" is the verb. "Warlock" is sometimes used for males, the complaints of neo-pagans notwithstanding. Silver Siren and Captain Kidd both bewitch people, though they probably wouldn't be called witches except in the context of using those powers.
Wizard: A mage who is capable of casting spells of his or her own, as opposed to sorcerers and artificers. Mystra, the Texas Hex, and Dr. Miracle are wizards. Enigma is both a wizard and a sorcerer. Erebus was a very minor wizard, but one with a highly unusual specialty.
Wrench: A super-genius gadgeteer. Since wrenches often do not have overt powers of their own and rely on their inventions, their relationship with the wider Super culture can sometimes be uneasy. Technoid and Hardhat were wrenches, as are FAQ and Silver Siren.
Zapper: To "zap" someone is to shoot them with some sort of energy. A "zapper" is thus a super who makes extensive use of zapping. If zapping is pretty much all a super does offensively, they are a "blaster". Bazooka is a blaster. Zappers who can also shape energy in more subtle ways are "Jedi". Photon is an electromagnetic Jedi. Energy elementals are often Jedi as well, but the reverse is not true - you can have the ability to shape energy without having the all-encompassing orientation that an elemental has.
Striking someone with a bolt of telekinetic "force" counts as zapping. Wide-spectrum, versatile telekinetics can even be called "shaker Jedi". Teke definitely qualified, though Mind Slayer was only a "shaker blaster".
