Marvel Universe
- Cap - Captain America. Has been canon for awhile, but still one of the most popular nicknames fans use for him.
- Cap's Kooky Quartet - The all-new, all-different Avengers lineup from 1965 consisting of Captain America and then newly reformed ex-villains Hawkeye, Quicksilver, and the Scarlet Witch.
- Bucky Cap - Bucky as Captain America. Another ascended nickname.
- Robo-Arm of Doom - Bucky's bionic left arm.
- Captain Falcon - Sam Wilson, the Falcon, in his role as the current Captain America. The joke writes itself, people (apologies to the F-Zero series).
- Falcap, Sam Cap, Snap Cap—other nicknames for Sam-as-Captain-America note .
- Captain HYDRA - the nickname given to Steve after it's revealed that he was a HYDRA agent the entire time.
- The Mighty Shield—the famous red, white, and blue shield carried by Captain America. Never referred to as such in the comics. Often referred to as such on fan discussion boards. Comes from the theme song to a '60s cartoon: "When Captain America throws his mighty shield!"
- Steeb—This nickname seems to be more popular in the movie fandom. It's just a cutesy mispronunciation of "Steve," useful when cooing over Chris Evans being alternatingly heroic and dorky.
- Shellhead—Affectionate nickname for Iron Man, used by his allies.
- Also often referred to as "Tin-Man", though less frequently.
- Der Eisenfuhrer—Tony Stark, after leading the effort to throw fellow heroes into the Negative Zone prison camp and becoming head of the Initiative. Usually used derisively by fans as a reference to bad writing (see also: Batdickery).
- Also known as "Bureaucrat in Chief" during his 'Director of SHIELD' era.
- When his armour became sentient and insanely possessive, it became known as Tony's "Abusive Boyfriend."
- Spidey—Spider-Man, though this one has been canon for a while.
- Spidey is even used in Marvel's handbooks, especially the Official Index to Amazing Spider-Man.
- The All-New, All-Different Marvel relaunch even launched a book titled "Spidey".
- Doc Ock—Doctor Octopus; another one that's become ubiquitous both in and out of canon.
- Iron Spider/Iron Spidey—The name for the suit worn by Spider-Man during the Civil War. It was designed by Iron Man and even used the same colour scheme. It's since been made official by merchandising and Marvel Ultimate Alliance 2. However, in at least one comic, guys dressed in copies of the suit are referred to as "the Scarlet Spiders" instead. This is fitting, considering that they're clones like the original Scarlet Spider, though not of Spidey himself.
- SpOck—used to refer to Doctor Octopus in Spider-Man's body during Superior Spider-Man (2013), as a combination of Spider-Man and Doc Ock. Other nicknames for him are Spider-Ock, the Inferior Spider-Man, Freaky Friday Man, and SS-Man.
- Spider-Gwen: The Spider-Woman of Earth-65, introduced in Spider-Verse as a Gwen Stacy that was the one who was bitten by a radioactive spider, not Peter. In an interesting example of this trope, it was quickly canonized when she gained her own solo series entitled Spider-Gwen. The character is almost never referred to as Spider-Woman except in her own comics. And even then, that's just in her own dimension, with other Spider-Heroes having no qualms with just calling her Gwen when she visits. And even then, people in her home dimension start calling her Spider-Gwen too after she publicly reveals her identity and the truth behind Peter's death. The third volume of her series, Ghost Spider, begins with her lamenting about how embarrassing it is have her real name as part of her hero identity, which segues into her casually thinking about getting a new codename circulating (which ends up being Ghost-Spider).
- Claremazon—Quite a few female characters (including but not limited to Storm, Sage, Shadowcat, and Psylocke) when written by Chris Claremont, who had a knack for creating strong super-heroines and powering up established ones (such as Marvel Girl becoming the Universe-Smashing Phoenix, or Moira MacTaggert now jumping into battle with an assault rifle). Also referred to as "Claremont Woman", to distinguish from the subdued damsels characterized as "Stan Lee girls".
- Claremontization: the accumulation/development of increasingly entangled continuity complications such as Kudzu Plots, Continuity Snarls, Retcons, Tangled Family Trees and Love Dodecahedrons over the course of a run on a title. Claremont is possibly the most famous instigator of this effect, during his X-Men runs.
- Boobilie/Boobilee, Wondra Bra—Jubilee (Marvel Comics) of the X-Men. The Decimation event making her lose her superpowers seemingly granted her the Most Common Superpower in exchange by the time she appeared in the latest New Warriors revamp as "Wondra", hence the name.
- Vampilee—Vampire Jubilee, her post-Wondra status quo.
- Pooky—Apocalypse. Also "Pocky" and "Ole Pokey Lips", the latter of which was coined by Deadpool (and Apocalypse does have some gigantic blue lips).
- Nimbo—Psylocke of the X-Men in her ninja incarnation. Portmanteau of "Ninja" and "bimbo", inspired both by her Leotard of Power and her playing the Femme Fatale trying to seduce Cyclops in the '90s. The term has been used for similar characters (e.g. Elektra and Zealot of the Wild C.A.T.s).
- Sniktbub—Wolverine; coined on 4chan from his two favorite catchwords, with inspiration from Pokémon Speak.
- Sniktdud (when people didn't like him much) and Sniktpunk (in reference to his hair)
- Sniktling—for Wolverine's son Daken. May also be used for X-23, as a general term for Wolvie's spawn.
- Trollverine has become the popular name for Daken.
- Sniktboob, Sniktloli, Girlverine, or Wolverine Girl for X 23, Wolverine's genderswap clone. The last one was used in canon in Avengers Academy #35. Currently, she's simply "Wolverine" (since the original holder of the name is dead).
- Honey Garbage is sometimes used derogatorily for X-23's clone Honey Badger.
- Also just "Wolvie" or "Our li'l Berserker-rager".
- Cyke for Cyclops
- After the events of the Mutant Messiah storylines, and everything after (when he developed an in-universe reputation as mutant Hitler and starting feuding with the Inhumans), fans started calling him "Rightclops."
- Due to the five original X-Men having been displaced in time to the present in All-New X-Men, they are collectively called the O5 whenever they need to be referred to as a group. I mean... what's the alternative? Actually calling them the "All-New X-Men"? That wouldn't be very appropriate.
- X-Men Corrections: Given to Chris Claremont's Word of God Fix Fic X-Men Forever, which attempts to convey how Claremont would have handled the X-Men franchise had he not departed the X-Books in the 1990s.
- The Heckfire Clubhouse - The Replacement Scrappy Hellfire Club made up entirely of Enfants Terrible.
- Also The Hellfire Kids or Hellfire Brats or Hellfire Babies. They get a lot of derisive nicknames.
- Wolverine and the X-Men new recruit Ira Dos Santos, due to her preview images, managed to pick up the nickname "Shark Tits". She was effectively a were-shark. Who retains her breasts in shark form.
- "The Pissing Contest" or "The Dick Measuring Contests", and various similar titles are often used to describe Cyclops and Wolverine's recent spat in the main comics and their split. Whenever the two meet and start arguing, usually someone will make a crack about them 'having another Pissing Contest'.
- The Juggernaut, Bitch - The Juggernaut, based on the parody. Some people actually refer to him by this in full.
- On a similar note to Darkseid (see DC), the Juggernaut since his Heel–Face Turn has been known as Jobbernaut, though since he got his powers back and it is implied that he will make a Face–Heel Turn, the name may soon be nonapplicable.
- "Young Man Cable" for the younger version of Cable seen in the Krakoa Era (and semi-officially known as Kid Cable), by analogy with Old Man Logan, and subsequent riffs on that for older versions of characters.
Assorted Marvel
- Marvel comics deserves special mention in that it propagated the use of nicknames to refer to many of its own characters with their "next issue" blurbs. For the record, Iron Man is Shellhead, Daredevil is Hornhead, Thor is Goldilocks, Hulk is Greenjeans, Jade Jaws, or the Jade Giant, Spider-Man is Webhead, the Webslinger, and Wallcrawler, etc, etc.
- If a franchise has multiple books with The Adjectival Superhero titles and one without, fans will term the one without as "The Adjectiveless [Hero(es)]".
- The Big Three - Captain America, Iron Man, and Thor; generally considered the cornerstones of the Avengers.
- Namor, the original Human Torch and Captain America when referring to Timely Comics (Marvel's Golden Age precursor).
- Teamwise is Avengers, Fantastic Four, and X-Men
- Bleedball - When Speedball had his powers changed during Marvel's Civil War crossover event, to the extent where he had to wear a iron-maiden-esque suit and was renamed "Penance". This wasn't well received by comic fans, when a otherwise happy-go-lucky character got changed so that he needed to feel pain for his powers to work.
- King of Everything - For Norman Osborn when the US Government decided he should be in charge of everything concerning supers.
- Rulk (the Red Hulk) was originally a fan nickname but has since gained official status in the books.
- Before even being confirmed as a real deal, a group of the most powerful villains in Marvel Universe Including Molecule Man, the Beyonder and Mephisto that appeared at the last page of Dark Avengers #10 were nicknamed The League Of Ultimate Evil And Enchantress.
- Shulkie - She-Hulk. Amusingly, the official writer that coined the term later went on a huge rant about people using fan nicknames like "Bats" and "Supes", saying it was disrespectful. This from the guy that nicknamed one "Shulkie".
- To be fair, it would hardly be the only example of rampant hypocrisy stemming from one of Byrne's rants against anything and everything he finds wrong with the comic world.
- Let's not forget "I've come to enjoy being called Polly," from Hippolyta. At least Jen is a deliberately playful character who doesn't take herself particularly seriously. The Queen of the Amazons, less so.
- Clor - The clone Thor, from Marvel's Civil War.
- This one may have since gained semi-official status, as Spider-Man has recently been cited as referring to him in universe as such.
- At one point, Joe Quesada threatened to have him officially named "Thone" (i.e., "Thor Clone"). His canon name has since been established as Ragnarok.
- As this was an increasingly annoyed Joe Quesada (also nicknamed Joe DeSade), said threat would be for Thone to stand for Thor-One and debut more Thor Clones unless everyone stopped complaining about Civil War.
- Earth-666: the Marvel Zombies reality.
- The Marvel Zombies official, canon reality number is actually 2149, as stated by the official website. Absolutely no idea where Earth 666 has come from.
- "Earth 666" is a play on "Earth 616", which is the mainstream Marvel Universe. Sources have been mixed as to why it's "616" but it generally is thought to do with the first publication date of Fantastic Four (In 1961, in the 6 month (June))". Generally, Marvel Universes are labeled by arbitrary numbers, though most have a connection to the publication date of the first comic to to take place in that Universe, though this isn't always the case.
- Funnily enough, in older translations of the Bible, 616 is the Number of the Beast, not 666. It works on multiple levels!
- Earth-666 has been officially assigned to an actual reality which is fillled with undead, but is distinct from the various Zombieverses, since it contains the whole Monster Mash.
- The Marvel Zombies official, canon reality number is actually 2149, as stated by the official website. Absolutely no idea where Earth 666 has come from.
- Iävengers - The 'evil' Avengers from the Marvel Cthuluverse as seen in Realm Of Kings.
- Subby - Namor The Submariner. Also used in-universe; Bucky Barnes is particularly fond of it.
- Fightbolts, Ellisbolts, Cagebolts - Various incarnations of the Thunderbolts, referring to the decried retool of the original series, Warren Ellis' run and Jeff Parker's current team led by Luke Cage, respectively.
- Cosmic Avengers - The Annihilators, an alliance of Marvel's space heroes. Started when the team was teased but an official name hadn't been released yet.
- Fans are fond of referring to the 2011 run of Journey into Mystery as Journey Into Misery
- Rainbow Dash - Julie Power, a.k.a. Lightspeed of Power Pack, who leaves a rainbow trail behind her when she flies.
- Alphalpha/Alfalfa - Alpha
- Hawkguy - Hawkeye, thanks to Matt Fraction's son.
- And before that, Lady Hawkeye for Kate Bishop, to differentiate her from Clint Barton. Became especially necessary once they both started using the name. Matt Fraction himself refers to her as Lady Hawkeye, as seen in the letters column.
- "Barakapool" for the In Name Only version of Deadpool seen in X-Men Origins: Wolverine. Headpool for the zombie version of Deadpool after he had his head chopped off.
- Nicole Fury/Nick Fury Jr. is used to refer to Daisy Johnson (Quake), since Nick Fury is her mentor and she uses his methods just as he would. "Nick Fury Jr." has since been claimed as the real name of an actual biological son of Fury's.
- As a very broad example, thanks to the All-New Marvel NOW! relaunch adding All-New to the beginning of several series' previously established names, fans generally just remove it altogether. For example, All-New X-Factor is generally referred to as X-Factor. The only series exempt from this are All-New X-Men, since there's already a comic called X-Men and the fact that it was the first title to use the adjective (it was launched with Marvel NOW! as opposed to All-New Marvel NOW!), and sometimes, All-New Invaders.
- All-New Ghost Rider is referred to as Ghost Rider or ANGR
- Snortblat: Thor. When the new, female Thor was revealed, a commenter on themarysue.com proposed the original be renamed "Snortblat", and site members gleefully adopted the name. While he has dropped the "Thor" name in canon, his official replacement name is "Odinson".
- Some fans have actually refer to Jane Foster/Female Thor as Woman thor. Beta Ray Bill is Thorse, and more often Beta Ray Bro.
- In his Maker guise, Ultimate Reed Richards is sometimes referred to as "Mr Creeptastic" in the fandom.
- The Social Justice Warriors - referred to the Avengers team of Captain America (Sam Wilson), Thor (Jane Foster), Nova (Sam Alexander), Spider-Man (Miles Morales), Ms. Marvel (Kamala Khan), and Vision.
- The community has taken to calling the terrigen mist clouds the "fart clouds."
