Shadowcat, on the other hand, remains perhaps the only female character in Marvel over the age of twelve to retain her petiteness. Although that's partly due to every writer at Marvel except Joss Whedon and Brian Michael Bendis having forgotten she existed.
New Mutants Wolfsbane and (usually) Moonstar are usually given petite frames and tomboyish haircuts, making them more cute than fanservicey. The few exceptions have either been by bad artists (*cough*Rob Liefeld*cough*) and/or just look ridiculous because all the past art has them slender.
Not a heroine, but Madelyne Pryor, when she became the Goblin Queen, achieved the supreme level of accomplishment in this trope. Her tattered costume featured an open middle that left only the tops of her breasts covered. Only the cosmic power of the Phoenix Force stood between her and a Wardrobe Malfunction of such epic proportions that it would have almost certainly led to a revival of The Comics Code.
Usually an aversion is the minor character Dust, who is Muslim and observes hijab, wearing a loose outfit that covers everything but her eyes. Even so, some artists draw it skintight.
X-23 initially doesn't strike one as this, until you realize that just about every uniform she has (give or take a couple) as well as the majority of her civilian clothes show off her navel. Her civvies also have a tendency to involve short skirts, Painted-On Pants, and corsets. Also, being a female clone of Wolverine, makes the embodiment of a whole category of fanservice.
Rachel Summers was this during her Excalibur days. When she was in the X-Men initially, she was a stick thin tomboy wearing very conservative clothes and costumes. Then she got abducted into the Mojoverse, and when she got back her body had become a lot curvier (apparently somebody remembered that she's supposed to look a lot like her mother, Jean Grey). Her costume was now a red, one piece leather catsuit with integrated heels and adorned with spikes. Her off duty clothes were not as risque, but only just.
Squirrel Girl (an aversion, originally portrayed as a bit of a buck-toothed Gonk, but sure looks nice in that Fur Bikini◊ and Big Bertha (a subversion, being a supermodel in normal-mode, and morbidly obese in super-powered mode).
Tigra is a twofer, being a Cat Girl who walks around wearing naught but a bikini. Later books have tried to justify this with Tigra saying wearing anything else over a full coat of fur would result in heatstroke, and the bikini is pretty much for modesty's sake.
Phantom Lady has been frequently called this, even in the real world US Congress. Her appearance was always fan services but her classic stories all tended to de-emphasize it.
One of the Sandman books has a segment set in a strip club.
Subverted with Power Girl in Justice Society of America: her body hasn't changed, but she's finally come into her own as a successful warrior and leader, to the point that she is now chairwoman of the JSA. She still provides plenty of fanservice though.
Archie Comics: Cheryl Blossom defined this in the 1980s (where it got her written out of the books) and '90s, where she was basically red hair on Pamela Anderson's face and body (the ones she had in the 1990s). Melody was this for Josie and the Pussycats, wearing the skimpiest outfits and drawing all the male attention.
Older than Television: Almost any female character in Lil Abner (which started in 1934) who wasn't an old lady, especially Daisy Mae, Stupifyin' Jones, Moonbeam McSwine and the Wolf Gal.
Tiffany, The Alpha Bitch from Luann, is this for the strip, giving much Snark Bait to online fans, considering the head writer is over 60, and Tiffany's a teenager. One memorable strip featured her in a string bikini, and most of the time she's just in a cheerleader outfit.
The British wartime newspaper comic Jane featured a title character who was always willing to help the war effort—which usually involved losing her clothes in some way. In Real Life, it was claimed that this actually helped boost troop morale. This may have been the first newspaper strip ever to include complete nudity, and was seen as unbelievably daring at the time.
There were rumours that when she appeared completely starkers it would be D-Day. Sir Winston Churchill personally intervened on the matter to make it so.
Modesty Blaise frequently depicted its title character in various states of undress, contrary to her name.
Ms. Buxley, from Beetle Bailey. She was even more so earlier in the 1970s and '80s.
June Morgan, the wife and nurse of Rex Morgan MD, drawn with a Patrick Nagel face and... prominent attributes.
La Mulatona from Clemente. Including when they show Clemente swimming between her breasts (a common scene in macrophile porn) as a running gag.
Gaturranta in the very first strips of Gaturro.
Irish Coffee's stripper girlfriend.
Wally Wood's Sally Forth, done originally for military papers, used any excuse to get the buxom but naive titular character out of her clothes. Not to be confused with the present-day strip of this name, which is about a fully clothed housewife.
Cythea in Necrophim, a beautiful succubus who never wears any clothes.
Averted in the DC series Manhunter: Street Justice, with protagonist Kate wearing a full-coverage bodysuit when she fights crime. Granted, she stole it from an evidence locker, but kudos to the author for making her different.
Vikki Vale in All-Star Batman & Robin The Boy Wonder spent the first few pages dressed in nothing but a pink bra and undies talking about how Superman is the "Man of Steel" for other reasons and all they had was a flying bat. When she found out that she had a date with Bruce Wayne, she ended up in very revealing dress. Frank Miller's script for that part reads less like Dark Knight Returns and more along the lines of Jay Naylor.
Little Ego. Ego exists solely to lose her clothes and get caught in erotic situations.
Durham Red in Strontium Dog generally wears a low-cut uniform and stands in a manner that emphasises her legs.
Liz, Jon Arbuckle's girlfriend in Garfield. Seen here◊. Yes, Garfield has fanservice. It's a new day. She's played in the movies by Jennifer Love Hewitt. So, yeah.
Thorn from Bone, not so much in early chapters, though. In later chapters, you get to see her bare legs quite a bit, and almost a little boobage due to Clothing Damage. There's even a gag (that actually is in an early chapter) where Fone Bone is nervous enough to accidentally eat a bar of soap because he's taking a bath with Thorn. (And before that, he watches a bird that seems to be there for the sole purpose of averting Fone's gaze away from Thorn while she's getting nude, before she goes into the water.) Needless to say, Fone Bone takes an instant liking to her.
Panda Delgado from Body Bags. She's only 14, but she sports a serious pair of breasts and wears a super-short cheerleader skirt and skintight sweater set. The skirt is so short the reader gets panty shots when she's standing still.
Parodied and subverted in The Boys where all the superheroines working for Vought American are turned into Ms. Fanservice as part of their image for merchandising. Takes a considerably darker turn when VA give Starlight a makeover consisting of high heels and a costume composed of about three grams of fabric due to them wanting her character to have been raped as a child and turn into a sex-crazed slut as a result. It doesn't go down well with her, especially when she reveals she was indeed sexually assaulted.
For the most part, Anderson in Judge Dredd doesn't provide much fanservice other than being hot in general. Her own spinoff, however, is a different story. In the first collected volume alone, she spends half a story naked in a coma (she is mostly covered by a sheet, but still), has another judge walk in on her in a shower, and goes clubbing in a low-cut, tight minidress.
Druuna, from the Italian graphic novel series of the same name, is either naked or wearing a skimpy tank-top-and-thong combo roughly ninety percent of the time.
Aunt Fritzi in Nancy.
Red Monika from Battlechasers. Huge boobs, ridiculous figure, big red hair and stripperific outfits? She's pure Ms. Fanservice.
Black Cat had a suit designed for Absolute Cleavage, made out of black PVC, and had a build that would require lots of surgery to get in real life, even more so that a lot of other heroes.
In a very weird way, Marvel has been trying to turn Carlie Cooper into this, most likely to increase her popularity. Low cut jeans, bared midriff, a tattoo that's near her lady bits but still visible in order to increase the midriff, and was probably the only girl in Spider-Island shown during the 'Naked New York' scene. However, because people just can't stand her, its been rather ignored.
Post Crisis Supergirl was a pretty infamous example, what with her cheerleader like costume, being introduced naked and later dressing in low cut jeans with her thong on display, and her constant panty shots when in costume. While most young teenaged girls in comics get treated like this, she does it to such a degree that it made many people uncomfortable, and was the source of many of her criticisms. Editors later issued a demand for this to be limited and/or stopped.
Barbara Gordon/Oracle/Batgirl is often described as having a buxom frame, and so she does. She's often designed as a Hot Librarian or with Nerds Are Sexy in mind. Despite that, however, she's still a tame example.
Selina Kyle/Catwoman is...well... Catwoman, a woman who goes around in tight leather and spends a lot of her time flirting with everyone around her. Even before she wore her now trademark catsuit, she was still quite sexualized. As if to spell it out to readers, in Death Of The Family she escapes a death trap that ripped up her outfit...and shows off an insane amount of skin!
Both Harley Quinn and Poison Ivy, the former often wearing a tight jester suit (and switching out that for what can best be described as a bikini designed to resemble her former appearance), the latter wearing next to nothing and looking, usually, like a naked woman with leaves placed in certain points on her body.
Cassandra Cain doesn't strike as an example due to her default design being a skinny young girl covered in scars. Still, her suit really clings to her like anybody else, and when she's not drawn as a skinny girl covered in scars, she's usually drawn like this. The Cruise issue of her series was pretty bad for it though, with her wearing a bikini for most of it (a thong bikini from the look of it), and later doing her crazy martial arts skills while wearing a dress she shortened, inducing pretty blatant panty shots.
Helena Bertineli/Huntress. With her short shorts/belly window suit being the main cause. One has to wonder how she can actually stay alive as a Badass Normal while wearing that suit. The artists behind Birds of Prey seem to be pretty fond of her rear end as well. Though, that's true for all the Birds.
Subverted with Stephanie Brown/Spoiler/Batgirl III. She's got a modest, realistic build, her Spoiler suit is designed with practical use in mind rather than sex appeal, while her Batgirl suit is just as practically designed, and most of her civilian appearances are in tomboyish conservative clothes. However, she briefly had a Thong of Shielding over her suit in place of the typical Underwear of Power, and while her suits are practical, they're usually just as skin tight as any other superhero suit, and just as susceptible to clothing damage as others. She was also heavily sexualized during the torture scene in War Games and her time as Robin, and her Batgirl series seemed quite fond of her in her bedroom wearing short shorts and showing off her butt as much as possible, leading to it being briefly lampshaded, with Oracle noting that people are currently getting a good view of her buttocks, or 'good side' as she put it, while they take pictures.
Deena Pilgrim from Powers. Putting aside her proclivity for wearing what she calls "little belly shirts", it's rare for her to go more than five issues without being shown either topless or completely nude. Also Callista Secor, a.k.a. the new Retro Girl, who wears tight shorts and a halter top as part of her costume. However, when she realizes what she looks like on TV (after her first escapade is taped), she's not happy.
Callista: God! You can totally see my asscrack! Now they're zooming in on it! Fuckers.
Brooke McEldowney's comic strip 9 Chickweed Lane had, and continues to have, a strong fanservice element to it in its depictions of female characters, most notably Edda. The later spin-off Pibgorn appears to be some 80% fanservice: The starting point of this strip is a menage à trois among an unassuming bespectacled pianist and musical arranger, and two devastatingly gorgeous supernatural entities who are devoted to him: a dark succubus called Drusilla and a red-haired faerie called Pibgorn. Neither entity wears very much at the best of times and the casual reader might suspect the script is written to get them naked as often as possible. Reprints of the strip in comic book form tend to add extra bonus material.
While Scott Pilgrim features many attractive women, Envy Adams is noted in Volume 6 to be "the perfect woman," with the proclamation being accompanied by her measurements: Bust 999, Waist 999, Hips 999.
Ramona also gets a lot of this kind of attention, and scenes of her in lingerie.
Almost absolutely all prominent female characters drawn by David Finch easily qualifies.
Toola from Pocket God. Booga and Klak went gaga over her at first sight. In fact, the creators of the comic admitted that she was designed as "the hottie".
In the Den comics, any woman from Earth arriving in Neverwhere becomes this; buck naked, buxom and liking it.
