Brought to You by The Letter "S"



"Kari: What does the 'S' stand for?

Syndrome: For, uh... sitter. Yeah, sitter. Originally I was gonna use the initials for 'Baby Sitter' but then I'd be going around with a big ol' 'BS!' And you understand why I couldn't go with that..."

- Jack-Jack Attack

Superheroes are in many ways much like athletes. Both frequently perform amazing physical feats we envy; both often collect themselves into teams with fancy names; both wear colorful, form-fitting uniforms.

And both have a tendency to adorn those uniforms with single letters of the alphabet. Stumped for a Chest Insignia? Just style up the first letter of your Code Name in sufficiently distinctive typeface, and have at it!

Anime and Manga

 * Ichi of Ichi the Killer wears a big "1" on his back, since his name means "one" in Japanese.
 * Similarly, Ah My Goddess's Keiichi, when he took part in the drag bike race, wore a jacket with "K-1" on the back. In the manga, he frequently signs his notes that way, as shorthand.
 * Mazinger Z: Although the original series avoided this, in later retellings and spin-offs Mazinger-Z wore a big "Z" letter in such the chest, the Hover Pilder or the Jet Scrander.
 * The big red R for Rocket of Team Rocket, general bad guys of the Pokémon series. Of course, there's also Teams Magma, Aqua, and Galactic - these three use a font style that's a bit more original, but there's still the 'M', 'A', and 'G'.
 * Team Rocket had a form of Lampshade Hanging of this in an episode. They set up a fake Pokemon Center by covering part of the letter 'R' painted on the wall with a piece of paper, making it look like the 'P' associated with Pokemon Centers.
 * Gai Shishioh from Gao Gai Gar wears a large "G" on the right side of his chest.
 * "G" is for the entire Gutsy Galaxy Guard. "J", likewise, is for the J-Ark Fleet, manned by Soldat J cyborgs. In both cases, the letter appears inside their Power Crystals (the G-Stone and the J-Jewel) when they get a powerup.
 * "G" is for... Speed Racer, because his name in the original anime is Go Mifune (he also wears an "M" on his helmet to represent Mifune Racing). His girlfriend Trixie has an "M" on her blouse, for Michi Shimura.
 * The late 80's comic version of Speed Racer by NOW Comics claimed that the "G" stood for Greg, which was Speed's real name in the comic (making him Greg Racer).
 * Chargeman Ken has a large letter "K" on his orange sweater.
 * Bleach's Ichigo Kurosaki has a 15 on his room's door. It becomes kind of a pun if you realize "Ichi" is 1 and "Go" is 5. Plus he's 15.
 * His sister refers to him as 'Ichi-nii', which, while short for 'Ichigo-niisan' (big brother Ichigo), is also similar-sounding to ichi-ni, which translates as "1-2". Ichi-niisan itself sounds a lot like ichi-ni-san, which is "1-2-3".
 * The Straw Hat Pirates of One Piece periodically wear shirts featuring numbers significant to them:
 * Luffy wears a '01' because he is captain or a '56' which reads 'go-mu'.
 * Zoro, next in command wears '02'
 * Nami wears a '03' as well as '73' (Na-mi)
 * Usopp wears a '04'
 * Sanji sports a '05' as well as '32' (San-ji) and '56' (Ko-kuu/kokku)
 * Dr. Minami in Heroman has an M on his shirt. Wonder why.
 * In Future GPX Cyber Formula, all the cars have numbers throughout the series.
 * The "S" in later Asurada models stands for "Sugo", the racing team the main character, Hayato is in. Shoemacher/Osamu in 11, also has the letter "S" in his racing suit. And Kaga's racing suit has the letter "Z" in it, as he belonged to Aoi ZIP formula.
 * Some of the team logos also has letters in it, like the "S" for Sugo and "Z" for Aoi ZIP.
 * "A" is for Action Kamen, though it's on his belt only. The Spanish dub completely ignored it and called him "Ultrahéroe".

Comic Books
""Remember when Guy used to fly around with that big G on his jacket?"
 * In The DCU ...
 * "A" is for Aquaman (and Aqualad) and Animal Man. Anarky also wears this letter, though as part of the "Anarchy-is-order" Circle-A.
 * "E" is for Element Lad.
 * "G" is for Green Arrow -- some artists draw his belt buckle with a noticeable "G" shape.
 * When his former sidekick, Speedy/Arsenal/"Red Arrow", adopted a red version of GA's costume, it included the "G"-shaped buckle at first. When the moniker "Red Arrow" became official, the belt buckle became a distinct "R".
 * "GG" is for Guy Gardner, during the period when he was operating as a superhero (using Sinestro's yellow ring) with no codename other than his own name.

"Remember what he said it stood for?"

"Yeah. 'Girl-magnet'.""


 * "GF" is for Geo-Force.
 * "i" is for Invisible Kid.
 * "L" is for the Legion of Super-Heroes - many Legionnaires (in the post-Zero Hour Reboot, all of them) have an L-logo belt buckle. The classic Legion flight ring also has an L. Un-boot Lightning Lad even has an L-logo tattoo.
 * "P" is for Phantom Girl.
 * "R" is for Robin. The resemblance of the original "R" logo to the official "registered trademark" symbol is uncanny, and has been the source of some humor in the past.
 * 'Registered Sidekick -- all rights reserved'...
 * "S" is for Superman (and "family"). He may possibly have been the Trope Codifier, since he is such a prominent example. Bizarro uses a reversed (twisted in the DCAU) "S".
 * Oddly enough, Superman's Jewish parody Shalomman uses the Hebrew letter shin, which is the initial letter of the word "Shalom." His bizarro-equivalent had the Hebrew letter sin, which in addition to being a shin-with-a-backwards-dot also made a pun on the word "sin."
 * No, Superman, the "S" does not stand for Shakespeare!
 * "S(blank)" is for too many homages/parodies of Superman to count.
 * In the 1978 film they make it clear that the reason for the S symbol is that traditional Kryptonian garb always included a chest insignia with a family seal on it, and the seal of Jor-El's clan just happened to look kind of like what we think of as the letter S. This is why Superman's outfit has that symbol on it already when it was made out of the rags he was swaddled in when he arrived in the crashed spaceship from Krypton even though it wasn't until later when the media gave him the moniker "Superman".
 * In 52 Ralph Dibny reveals that the S is actually the Kryptonian symbol for the word "hope". Upside-down, it means.
 * Superman once defeated a Proud Warrior Race Guy called Draaga in gladiatorial combat on Warworld. In the comics, Draaga wore a replica of Superman's costume, while on the Justice League cartoon he actually burned an "S" symbol onto his chest - in both cases this was so he wouldn't forget his failure.
 * "T" is for Tasmanian Devil (of the Global Guardians and Justice League Europe) and Red Tornado. The current Mr Terrific has a T-shaped mask. Well, unless that's just facepaint.
 * "W" (and occasionally "WW") is for Wonder Woman, when she's not using an eagle insignia. In a few continuities, like Kingdom Come, the two are combined: a stylized eagle that happens to resemble a W.
 * "Z" is for General Zod - at least the Polkistanian version.
 * In the Legion of Super Heroes "Z" is also for...well, the guy wearing it is named Drax, but considering Drax is a kid from the Phantom Zone, a safe guess would be "General Zod," presumably his father figure.
 * Depending on the costume, the Elongated Man has an E and an M.
 * Perhaps depending on how far his costume is stretched?
 * "F over A" is for The First American from Alan Moore's Tomorrow Stories, published by America's Best Comics, an imprint of Wildstorm Comics.
 * "Ω" (Omega) is for Omega Effect, so Darkseid's most recent costume has a Greek letter Ω as a Chest Insignia.
 * The Chinese character for the number "7" is for the Great Ten's Seven Deadly Brothers.
 * "?" is the Riddler.
 * In the Marvel Universe ...
 * "A" is for Captain America (on his head) and Apocalypse (on his belt buckle).
 * "D" is for Demolition Man (sometimes just called "D-Man"). Two means Daredevil... though this gets a little complicated when you realize that Daredevil's original costume really did have the one "D", and is in fact the very same costume worn by D-Man.
 * "F" is for Flatman, a member of the less-than-astounding Great Lakes Avengers X-Men  Champions Initiative.
 * "G" is for Galactus (on his belt buckle in his first appearance).
 * "H" is for Hawkeye. And Hardball.
 * "I" is for Mr Immortal, the Man Who Can't Die No Matter How Much He Really Wants To, and leader of the aforementioned Great Lakes Initiative. His 'I' is in multiple places, with 'Mr.' written inside the letter itself, since it's just a big rectangle anyway.
 * "N" is for Nomad.
 * "P" is for Puck (of Alpha Flight).
 * "S" is for Sentry (on his oversized belt).
 * "T" is for Thor (sometimes — it's on his belt buckle in the Silver Age) and, by extension, Thunderstrike.
 * These days, Thor's belt buckle is the rune uruz (basically the letter "u"), because the Uruz rune was traditionally used to represent the god Thor. It also represents strength and virility. In addition, "u" stands for "uru", from which Mjolnir is made.
 * "W" is for Wonder Man (when he's not using Civvie Spandex).
 * "X" is for the X-Men's "x-factor" or "extra factor" in their mutated genes.
 * Not a letter, but each member of the Fantastic Four goes into battle with a large "4" emblazoned somewhere on their uniform.
 * "MM" is for Miracleman/Marvelman.
 * Jughead Jones typically wears a sweater with the letter "S" on it...the meaning of which is known only to Jughead.
 * In Johnny Saturn the Utopian, as an example, wears a stylized "U" on his chest. A variation of this would be Titanium Tom, who wears a patch on each shoulder with Ti-- the symbol for titanium.
 * The revived Darkwing Duck comic books featured many Darkwings. If they were Darkwing versions of other heroes, they'd have a 'DW' or 'D' on them (such as the Incredibles version).
 * In Son o' God comics, Jesus wears spandex with a cape and a "JC" on his chest.
 * In All Fall Down, S is for Siphon and P is for Paradigm.

Fan Fic

 * Holographic Retro of Calvin and Hobbes The Series has an "H" on his forehead.

Film

 * In The Incredibles:
 * "i" — distinctly lowercase with a prominent dot — is for Mr. Incredible, and later his whole family.
 * "EG" is for Elasti-Girl; she dropped this after the intro of the movie, for plot-explained reasons.
 * "S" is for Syndrome.
 * "G" is for G-Girl, from My Super Ex Girlfriend. G-Girl was notable for not having just one costume but (being a hip New Yorker) a whole closetful, each distinguished only by a "G" motif.
 * Interestingly, she never explains what the G stands for.
 * "1" in an "engraved" style similar to that on the one dollar bill for U.S. Bill of The Specials.
 * "M" is for both Megamind and Metro Man.

Literature
" 'You haven't got a letter on yours [Ron],' George observed. 'I suppose she thinks you don't forget your name. But we're not stupid -- we know we're called Gred and Forge.' "
 * In Harry Potter, Mrs. Weasley gave her sons knitted sweaters with letters on them one Christmas. P for Percy (or "Prefect" if you ask Fred or George), F for Fred and G for George. On the other hand...


 * And in the movie at least, Ron gets one with "R" on it.
 * The eponymous letter in The Scarlet Letter. It's a red 'A', which is supposed to stand for "adulteress", but since Hester, the woman sentenced to wear it, is so helpful to the people in her community, they start to believe it stands for nicer things, such as "admirable".

Live Action TV

 * "?" is used by the Fourth, Fifth, Sixth and Seventh Doctors in Doctor Who, possibly related to the fact that his signature contains a question mark.
 * The Cybermen of series 2 and the 2008 Christmas Special feature a 'C' on their chests, standing for Cybus Industries, the organization that created them. The Doctor lampshades this, saying that they have been 'franchised'. The Cybermen that appeared in "The Pandorica Opens" still used this design, despite being the original Mondas Cybermen, due to budget issues.
 * "CH" is for Chapulin Colorado.
 * "G" is for Super Grover.
 * "V" is for Major Victory, a season 1 contestant on Who Wants to Be A Superhero?.
 * From Kamen Rider:
 * "V3" is for Kamen Rider V 3 (the 3 is tiny on his belt buckle, but it's there)
 * "X" is for Kamen Rider X
 * "S" is for Kamen Rider Stronger, with "T" used in sidekick Tackle's breast designs.
 * "RX" is for Kamen Rider Black RX
 * In a non-Latin example, the Greek letter "Phi" is for Kamen Rider Faiz.
 * "Chi" is for Kaixa
 * "Delta" is for Delta
 * "Rho" is for Riotrooper
 * "Psi" is for Psyga
 * "Omega" is for Orga
 * Kamen Rider Decade, celebrating the 10th year of the show's Heisei era, sports an "X" for 10.
 * "W" is for Kamen Rider Double (the Japanese often use the letter "W" as a shorthand for the word "double"). All the show's Riders and Monsters of the Week fall under this trope, as their Transformation Trinkets bear a letter made from a stylized representation of whatever power they possess.
 * "A" is for Accel, Anomalocaris, and Arms.
 * "B" is for Bird, Beast, Bomb, Bean, and Bat.
 * "C" is for Cyclone, Claydoll, Cockroach, and Commander.

 * "U" is for Utopia and Unicorn.
 * "V" is for Virus and Violence.
 * "W", besides Double, is for Weather.
 * "X" is for Xtreme.
 * "Y" is for Yesterday.
 * "Z" is for Zone.
 * Non-superhero example: In Laverne and Shirley, "L" is for Laverne DeFazio. She has a cursive "L" on every blouse, shirt and sweater she owns. This was carried over to her military uniform in the Animated Adaptation.
 * In the 1970s PBS children's series The Electric Company, a recurring cartoon feature, "The Adventures of Letterman", had the eponymous hero sporting a different letter on his "varsity sweater" each episode; his power was the ability to change one object into another by replacing a letter in its spelling. When his arch-enemy, the Spellbinder, fired a dart at him, Letterman replaced the 'd' with a 't', turning it into a tart, which he then ate.
 * The Ambiguously Gay Duo have G for Gary and A for Ace. Unsurprisingly, there happened to be times when they had to stand next to something large and Y-shaped.
 * Betty Suarez of Ugly Betty wears an identical "B" necklace.
 * From Super Sentai and Power Rangers:
 * The members of Goranger all wear belt buckles shaped like a "5" (as in "Go" for five), while each of their helmets are individually numbered from 1 through 5.
 * The four main members of J.A.K.Q. wear belt buckles shaped like a "J", as well as individualized helmets and badges engraved with the first letter of their respective "rank" (Jack, Ace, King and Queen). Big One wears a belt buckle shaped like a "B1" and a helmet with a "1" engraved on it.
 * "BF" is for Battle Fever on the chest of the Battle Fever Robo. The individual members of the team have the first letters of their respective countries engraved on their belt buckles as well (Japan, America, Kenya, France and Cossack, who represents the Soviet Union ).
 * "D" is for Denziman, with the letters on the belts for "I [color]" (i.e. Denzi Red has "IR", Denzi Blue has "IB", ect.). The "I" is actually the left half of the letter "D" that forms the main emblem on their badges.
 * Sun Vulcan has a general "V" design that stands for "Vulcan". The Sand Vulcan jeep is also adorned with the letters "SV" as well.
 * The members of Goggle-V all wear a badge with a "V" symbol (a roman numeral five), as well as belt buckles with "GV" engraved.
 * "D" is for Dynaman on their badges, plus a roman numeral and "D[letter]" for Dyna[color] on their helmets.
 * "CM" is for Changeman on their belt buckles and gloves.
 * "FM" is for Flashman on their belt buckles.
 * Subverted by the "5" in Hikari Sentai Maskman, which doesn't stand for anything despite appearing prominently on the chest of each member (it was an artifact from when the show was going to be titled "The Fiveman").
 * "LM" is for Liveman on the waist of the Live Robo.
 * Another general costume design resembles "T" for Turboranger. We also have on their belt buckles: GT (for Grand Tourer) on Red, T (for Truck) on Black, J (for Jeep) on Blue, B (for Buggy) on Yellow and W (for Wagon) on Pink.
 * Another team with "V" costume designs can take it as the roman numeral for Fiveman. The symbols on their helmets are related to the Hoshikawa siblings' day jobs as school teachers: Five Red (a science teacher) has an atomic symbol, Five Blue (a gym teacher) has a figure of a running man, Five Black (a Japanese language teacher) has the kanji for 'language', Five Pink's symbol (who is a math teacher) is a combination of several mathematical signs (specifically of addition, subtraction, multiplication and division), and Five Yellow (a music teacher) has a quaver (or eighth note).
 * "Z" is for Zyuranger; not on the Ranger suits but on the backside of the belt buckles (visible on the civilian outfits) and on the mecha. When it shows up in Mighty Morphin Power Rangers (Season 1), it can be implied to mean "Zordon".
 * "D" is for Dairanger. Its counterpart, Mighty Morphin Power Rangers Season 2, dropped this but added a villainous version with "Z" for Zedd.
 * "N" is for Ninjaman (in Ninja Sentai Kakuranger) and Ninjor (in Mighty Morphin Power Rangers Season 3). Oddly, when Ninjaman powers up into Samuraiman he changes his emblem, yet it still resembles an "N" instead of an "S". (Power Rangers doesn't have this problem because Ninjor keeps his name in both forms.)
 * King Ranger had 王, the kanji for "king", on the face of his helmet and on his staff. It provides a Bilingual Bonus in Power Rangers ZEO.
 * "C" is for Carranger. (Power Rangers Turbo ignores this completely and it's just a generic logo.) Also (in both shows), "S" is for Signalman and Blue Senturion.
 * "M" is for Megaranger (again, just a generic logo in Power Rangers in Space). This also shows up on the mecha in non-logo forms, though the later ones' "MV" and "MW" (Mega Voyager and Mega Winger) do apply to Power Rangers as those names weren't changed. In addition, "N" is for Negiranger, but this also is ignored in the US as we call them the Psycho Rangers instead.
 * "H" is for Hurricaneger or, probably more accurately, Hayate Ninja Academy. (Once again, it doesn't stand for anything in Power Rangers Ninja Storm.)
 * "SPD" is for Special Police Dekaranger or Space Patrol Delta. They also have numbers on their chests, "1" to "5" for the main team and "100" and "VI" (6) for the extra members, plus the occasional One Shot Character with a potentially odder number:
 * "M" (1000), which some also take in a roundabout way as 7 (M -> IVI -> VII).
 * One with no blatant number, but the design on the chest can be interpreted as "8", "白" (the kanji for "white" - which resembles 百, the kanji for a "hundred" minus one stroke, making her 99), or a heptagon representing seven.
 * Dekaranger only: "X" (10)
 * SPD only: A Ranger wannabe wears, appropriately enough, 0.
 * "M" is for Magiranger and Mystic Force. In the same series, "W" is for Wolzard and Knight Wolf and "S" is for MagiShine and Solaris Knight.
 * AkaRed, the living embodiment of every red ranger in history, originally wore a badge engraved with the number "30" during his first appearance in Go Go Sentai Boukenger vs. Super Sentai (which commemorated Sentai's 30th anniversary). This was updated to "35" when AkaRed returned as a semi-recurring character in Kaizoku Sentai Gokaiger (the 35th Super Sentai show).
 * The main Go-Ongers and RPM Rangers also have numbers 1-5 on their chests. There's also a "G" for Go-Onger in various places (including on the chests of the Sixth Rangers in place of a number), but it's another that's stylized enough to serve as a generic logo in RPM.
 * The Shinkengers and Samurai Rangers wear the appropriate Japanese kanji (火 fire, 水 water, 木 wood/forest, 土 earth, 天 sky, and 光 light) on the visors of their helmets.
 * "B" is for Basco in Kaizoku Sentai Gokaiger.
 * "GB" is for Go-Busters.
 * "A" is for Akibaranger- their logo is actually a combination of the letter A and the kanji 非, which means "non-" and is the first character in the Japanese word for unofficial, so it's sort of a bilingual example.
 * Seiun Kamen Machineman has "M" for the titular character, in both his superhero form and his Cool Car-Cool Plane vehicle.

Professional Wrestling

 * "H" is for Hurricane, former resident superhero of the WWE. "R" is for Rosey, his boy (well, 300-pound Samoan who acts like a boy) sidekick.
 * "R" may have been Rosey's insignia once he graduated from sidekickery, but first he was a "Super Hero In Training" (S.H.I.T.).
 * Scott Steiner used the Superman S — actually the full Superman logo, until the expected legal action forced a change to an S in an ellipse.
 * In another non-superheroic example, during his WWE tenure, the number "13" was for Tazz. According to Tazz, the "13" represented the bad luck his opponents must have had to have drawn him as their opponent for the evening.
 * Some of Kurt Angle's singlets featured an "A" inside a Superman-esque shield, obviously standing for Angle. In his typical smartass fashion, The Rock came up with his own vulgar ideas of what the "A" stood for.

Tabletop Games

 * Yu-Gi-Oh: H is for Elemental Hero, but D is for Destiny Hero and N is for Neo-Spacian (although just to be confusing, one Elemental Hero works with all Neo-Spacians). Not to mention that each of the letters of the word 'Hero' has its own card. Since one of them gets any Elemental Hero from the deck to your hand, and another Special Summons an Elemental Hero from the Graveyard, this could be a literal case of Brought To You By The Letter S (or in this case, E/O).

Video Games

 * Akuma from Street Fighter has a winpose where the kanji for "heavenly sky" shines on his back, usually done after defeating an opponent with his Raging Demon super. It's pronounced "ten", by the way.
 * "M" is for Mario, "L" is for Luigi, "W" is for Wario, and logically enough, "Γ" (capital Gamma) is for Waluigi. All these symbols appear on characters' hats, rather than on their chests.
 * City of Heroes' ridiculously extensive costume creator gives you a choice of the entire uppercase Latin alphabet and figures 0–9. After six months of subscription, players get to access all letters of the Greek alphabet, uppercase and lowercase.
 * Although ironically for a superhero game, not many players follow this trope.
 * Klavier Gavin (Kyouya Garyuu in the Japanese version) in Apollo Justice: Ace Attorney has a G pendant.
 * DK! Donkey Kong! On his tie, uniquely enough, but it's also his only piece of clothing.
 * In Mega Man Zero, Copy-X wears a jacket that crosses over his chest like an X (as do his four Guardians) and Cyber-Elf X looks like a ball with a rainbow X around it, foreshadowing his identity. In Mega Man X 8, X's earpieces have X-shaped lights.
 * Marisa Kirisame's design in the 12th Touhou game, Undefined Fantastic Object, gives her an apron with a large "M" on it.
 * Hina Kagiyama, a curse/misfortune goddess, has a stylized kanji 厄 (yaku) on her dress, meaning "misfortune".
 * In Space Channel 5 Part 2, "P" stands for Purge.
 * Twilight Heroes features the "letter shirt" for its superheroes, which can be customized to show any capitalized letter in the English alphabet.
 * Picky Minch from Earthbound wears an M on his shirt, for "Minch". His clay model artwork shows a P on the shirt instead, probably for "Picky".

Web Animation

 * In Homestar Runner, "M" is for Strong Mad. Coach Z wears a medallion with a stylized letter "Z" on it.
 * "TH" is for Bubs' alter ego, the Thnikkaman.

Web Comics

 * In PS 238, a Batman-like hero called The Revenant wears a stylized letter "R" on his chest.
 * Mister Mighty, of Everyday Heroes, of course wears a gold "M" in an oval.
 * His teammate, Dot Dash, wears a dot-and-dash on her chest; Morse code for the letter "A". This is one of the most convoluted Punny Name references ever: The dot is for her first name Dorothea, the dash is for her super-speed, the "A" is for her maiden name of Axel, and Morse code for her married name of Morse.
 * In The Inexplicable Adventures of Bob, after Bob very briefly becomes a Superhero and then loses his powers, he says his one real regret is that he used a permanent laundry marker to make the "B" logo on his shirt.
 * Evan from The Wotch always wears a shirt with a capital "E" on it. Lilly wears a dress with a lil' 'e' on it instead.
 * "50", as found on the back of America's jacket, stands for the 50 states, natch. This detail was removed in the anime.
 * Homestuck: When Kanaya imagines a troll version of, she wears a dress with her initials,.
 * The actual trolls themselves are this as well, in a strange and roundabout way. The symbols the trolls wear on their shirts are twelve out of thousands which just so happen to coincide with our own zodiac symbols. Each color acknowledged by the hemospectrum has a library of hundreds of symbols associated with it; every troll is assigned one after they pupate, and they must wear it somewhere upon their person their entire lives. This symbol acts as a single-character signature for them and they may, in fact, sign documents with it.

Web Original

 * 'P' for Phase, in "Boston Brawl II" of the Whateley Universe. Since Phase is a density changer like the Vision, the 'P' starts out dense at the top and fades away at the bottom. Phase hates it.
 * 'C' is for C the speed-of-light-octogenarian in Legion of Nothing.
 * 'J' for Jock, a super-athlete with heightened reflexes from the Global Guardians PBEM Universe.
 * 'E' for Embrace, a stretchable supervillain. Also for Echo, a superhero with ultrasonic powers.
 * 'A' for Apex.
 * 'V' for Velocity.
 * There's even one villain with a number: '8' for Eight-Ball.
 * 'S' for Simon of the Yogscast in real life: He wears a distinctive blue Superman hoody. For a time in 2011, Simon's character Honeydew in the Yogscast Minecraft Series had a metallic S symbol over his chest, which Simon claimed was for Simon AND Superman.
 * In Neopets, most Aishas have collars with the letter 'A' on them. The Darigan-colored one has a 'D' instead, and the Snot-'colored' one has an 'S'.

Western Animation

 * "A" is for Alvin, as in Alvin and The Chipmunks.
 * "R" is for Richie Rich, at least as Hanna-Barbera animated him.
 * "M" is for Marvin White, the aspiring superhero in the first season of Superfriends.
 * "J" and "Z" are for Jayna and Zan, the Wonder Twins.
 * In the classic Bugs Bunny short "Super-Rabbit", "S" stands for Super too.

 * I.R. Baboon from I Am Weasel has an upside-down "IR" scribbled on his shirt.
 * After fiddling around with casual outfits for José Carioca's comic book series, they eventually settled on a T-Shirt with a "Z" on it, for "Zé".
 * "8" is for Manic 8-Ball, a one-shot villain from The Venture Bros.
 * "DP" is for Danny Phantom (the "P" is inside the "D").
 * And Dani Phantom.
 * "F!" is for Freakazoid.
 * "H" (inside a male symbol) is for Captain Hero of Drawn Together. It's actually his real name, though (Leslie Hero).
 * "A?" is for a Canadian superhero appearing extremely briefly in an episode of ''Eek the Cat.'
 * "A" is for Atom Ant.

 * "L" is for Larry Fine of the Robonic Stooges (and "M" is for Moe and "C" is for Curly, of course(.
 * "M" is for Multiple Man of the Impossibles, for his namesake of the Super Globetrotters and for Moe Howard of the Robonic Stooges.
 * "Q" was (briefly) for Quiverwing Quack; Darkwing Duck's daughter really wants in on the family business.
 * "SD" is for Scooby Doo (on his engraved dog-tag).
 * "SG" for Super Goof as he appeared on House of Mouse and in the comics.
 * "U" is for Underdog.
 * "N" is for Captain N the Game Master.
