Post-CrisisJason Todd was hated by quite a few readers, to the point that fans eventually voted for him to be killed by the Joker. While an almost equal number of people voted to spare him (it is rumoured that at least three hundred of the votes were from the same caller), a lot of people thought that the vote was for the first Robin, Dick Grayson, who was excessively popular amongst a lot of fans, and that's not a rumour. Funnily enough, he was brought back to life due to Alas, Poor Scrappy status, where he became an anti-hero Jerk Ass Woobie who was centre stage to a very well received storyline. This was only helped by the Batman: The Dark Knight Returns where it's implied that Jason's death helped lead up to this future where Batman retires, ending with a brawl in crime alley against the Man of Steel.
Harper Row. Created when DC wouldn't let writers use Cassandra Cain or Stephanie Brown, she was liked well enough until Cass and Steph came back and she continued to steal their narrative space. Steph and Cass, best friends in the pre-New 52 Universe, now tolerate each other for Harper's sake and barely interact. She somehow goes from a self-taught technician to acrobatic genius at everything from weapons to software, to the point that she was established as being a better hacker than Tim Drake, the hacker in the Bat-family. It got even worse when it was revealed that Harper Row is kinda central to Cass' entire motivation. Harper is also now the 'uber Robin': the somehow scientifically predestined best choice in Gotham for Batman's sidekick. Yes, objectively, she was destined to be the best Robin. Thankfully, Rebirth seemed to kick her out of focus again, but it might not stick.
The Riddler. Not as bad as most others, but is generally labelled as the lamest of the big name rogues, with a mental disorder (OCD) that many find dull in comparison to the others. Emphasizing him as a "technically legal" villain has since quieted some of them down. Though back in the Golden Age and Silver Age, he actually was one of the most popular villains, mainly from Frank Gorshin's manic portrayal on Batman.
Captain Atom villain Major Force developed quite the hatedom over the 2000s. It'd be one thing for him to just be a boring villain with an ugly outfit, but Major Force took it further by being a complete Jerkass with no redeeming qualities, including being the cause of multiple cases of Stuffed into the Fridge (even being the Trope Namer). Worse, for a good chunk of the 2000s, he just kept showing up - whenever a writer wanted to have the government do something morally ambiguous, they'd bring in Major Force. From then on, the following plotline would play out: Major Force acts like an asshole to his more reasonable government buddies, Major Force loses his temper and brutalizes somebody, the hero fights Major Force and seemingly kills him, Major Force comes back in a few months to do it all over again in another book because he's an Energy Being and can't die. Fans are irritated enough by Joker Immunity when it applies to villains who they like.
Cyborg in the New 52 Justice League series is one for many fans of Martian Manhunter due to him replacing J'onn as a founding member. Ironically, this also counts for his Teen Titans fans, as Vic went from having a support network in his team to just having a business-like relationship with them.
Holly Granger, the female Hawk. It doesn't help that the original Hawk (Hank Hall) was changed into a villain with Armageddon 2001 thanks to an Ass Pull when Captain Atom was leaked as Monarch and DC wanted to keep things a "surprise". Then come 2005, after Dawn Granger/Dove II's death was undone with a convoluted and squicky explanation: Dawn, an only child in the Hawk and Dove series, suddenly shows up to the Titans with a bratty younger (or older?) sister in tow that was living away in England all the while. Fans of Hank Hall immediately cried foul on Holly, for not only did she have an inconsistent and unlikeable personality, but her existence also retconned the fact that Hank and Dawn's powers were bound to them and could NOT be passed on to anyone else. It wasn't uncommon to see those fans wishing death on her and wanting Hank back with an Author's Saving Throw. In the end they got their wish with Blackest Night.
Before Holly and long before Dawn's comeback, DC attempted to do a completely different take on Hawk and Dove, with an army brat named Sasha Martens and a slacker musician named Wiley Wolverman gaining the power to sprout bird wings and fly, as well as telepathy. Due to them being a case of In Name Only and not being received very well by H&D fans, these two wound up vanishing with no explanation given, not even showing up as cannon fodder for big events. Would it have helped if the artist had known how to draw bird wings that don't appear to be suffering from both crippling arthritis and mange? Guess not...
The character Magog was hated by a lot, partially because he's a massive Jerkass who got a lot of time on screen. A LOT of people also cite him hittingMaxine'Cyclone'Hunkel when she was flying overhead because 'she came at him from his blindspot.' Magog has also been accused of being a mouthpiece for writer Bill Willingham's right-wing views; fans were quick to call Unfortunate Implications when Magog took center stage in an arc that also featured Obsidian (who is gay) being turned into an egg and Mister Terrific (who is black and atheist) being shanked in the back like a street thug (both eventually got better). The fact that he was originally created as a direct criticism of the "jerkass superhero" archetype in Kingdom Come (where, ironically, his perception was quite the opposite) has only made fans more pissed at what they've done to the character. Eventually, Magog's luck ran out. He got kicked off the Justice Society, and his series was cancelled after less than twelve issues. The next time Magog appeared it was in order to be brainwashed by Max Lord, fatally poisoned, then made to kill himself by Max.
A minor example among queer readers is the villain Endless Winter. Originally, she was Delores Winters, the actress whose body was hijacked by the Ultra-Humanite. In a JSA Classified arc, Delores became an Ascended Extra where her life after her body was stolen was explored. The doctor who removed her brain felt pity for her and gave her a new body, but Delores thought it was hideous and began demanding organ transplants. Eventually she started kidnapping superheroes and villains to steal their empowered body parts, such as Loose Cannon's heart and Godiva's hair. What made her so hated was that she had Icemaiden, one of the few openly bisexual characters DC had (and she'd been around for over thirty years), completely skinned alive. And what's worse is Icemaiden survived, but was last seen comatose. Fans were outraged at such deplorable treatment and thus immediately hated Endless Winter. In her last appearance, she was killed off in Justice League: Cry for Justice while fighting Batwoman.
Lori Morning wasn't very liked by fans, as she was a bratty Tagalong Kid that lacked powers, only being able to use her H-dial to morph into random superheroes. The fact that the creative team intended to be a younger version of the villainess Glorith didn't help matters. Putting her on a bus was one of the first things to occur once a new creative team took over.
The 1994 reboot versions of Princess Projectra and Wildfire got this due to their radically different origins. Projectra went from being a princess to a giant talking snake, while Wildfire became the result of a Fusion Dance between two minor supporting characters. The later never recovered though the former did garner a level of popularity.
Tyroc, the first black character to join the Legion, combined this with some Unfortunate Implications: He was an angry black man-type character whose backstory implied that the 30th century was actually that racially segregated, with him and others living on an extra-dimensional island. His superpower was to warp reality by screaming. Mike Grell had intentionally given him a ridiculous costume, as he hadn't liked the concept of the character. After the original Legion continuity became prominent once again, Tyroc was returned to the team, with his controversial origin never mentioned and a less ridiculous new costume, to the relief of many.
The SW6 version of Sun Boy, who later changed his codename to Inferno, was a ginormous asshole who embodied all of Dirk Morgna's worst traits. He was an egotistical lech and a bully whose harsh treatment of poor Cera Kesh made her quite susceptible to the influence of the Emerald Eye of Ekron, turning her into the new Emerald Empress. Beyond that, fans found him especially grating because he swore he wouldn't become as bad as he older counterpart (who betrayed Earth to become famous and paid for it when radiation turned him into a deformed, burning corpse) yet somehow became worse. It's entirely likely the reason the Reboot Legion didn't have a Sun Boy (although Dirk Morgna was a semi-reoccurring character) and the Inferno name was given to a completely separate character, was because fans hated this one so much.
Atmos, a supporting character from the third volume Legion series, has no fans. Starting off with his horrendous design (such as his giant mohawk and how his armpits turn invisible), he was a Small Name, Big Ego character who tried out for the Legion and seduced Dream Girl while her relationship with Star Boy was turning rocky. Any chance he had of being likable in the eyes of the readers vanished when it turned out he also had slight mind control abilities and forced Dream Girl into a sexual relationship, which meant he raped her. Fans cheered when Nura socked him in the jaw after she figured this out. During the Glorithverse volume, it was mentioned Atmos joined when the Legion was desperate for members, and in his last appearance before the Reboot he was killed by B.I.O.N., an android constructed by the Dominators.
The post-flashpoint design of Lobo has proved incredibly unpopular, on account of missing every single aspect of Lobo his fans like, and being a ridiculous "pretty-boy" look. The fact that the comic that introduces him goes on to say the Lobo fans have known for decades now is a "fake" really doesn't help. Seemingly it's been restored in DC Rebirth, with the new "real" Lobo sealed away by the Green Lantern corps.
Superboy-Prime since his FaceHeel Turn in Infinite Crisis, mainly because he became DC's Straw Fan, mouthing common fan complaints while committing villainous acts. Although most of his most infamous moments were rendered non-canon (no one got out of Countdown to Final Crisis unscathed), people still haven't forgotten them OR the stuff that is canon. It certainly didn't help that DC kept ramping up his powers and refusing to kill him off, or that he usually escaped his crimes (which included beating the Golden Age Superman to death) without significant comeuppance. There was a rather awful period in DC where writers kept coming up with progressively more extensive ways to remove him from canon, each time swearing it would be the last one, only to then have him return two or three months later.
Supergirl: Cir-El, the "daughter" of Superman and Lois Lane from the future where Brainiac 13 existed. She showed up during the time the Matrix Supergirl was phased out and was not very well liked for a number of reasons, including being a kid from the future. Thankfully for fans, she retconned herself out just in time for Kara Zor-El to return. However, if you were to look up Cir-El on tumblr, you'd be surprised to find that she has a large number of fans with emphasis put towards the less convoluted aspects of her backstory. Said fans like to view her as the daughter Superman and Lois Lane could have had, enjoying her bubbly personality, her desire to follow Superman's example, a really neat and distinctive costume and appearance, and her short-lived team with Traci 13 and Natasha Irons.
Superman: General Zod. The main reason for this is that his appearance in Superman II means that he keeps showing up far more often than his scant decent stories would warrant, and without Terrence Stamp's hammy performance backing him up, he rarely attains any characterization beyond "is evil space general." This was particularly comical for a period when editorial mandated that no new Kryptonian characters be introduced; the result was that the writers introduced a new, non-Kryptonian Zod, who proved to be unpopular and quickly faded from existence, only for the writers to introduce another Zod and repeat the process. This happened four times, and when the period ended, they brought in a fifth Zod who was Kryptonian.
Danny Chase. Not only did he actually look like Cousin Oliver, but everyone hated him. He mocked Jason Todd's death (in front of Dick Grayson, Jason's adopted brother) and his sole Crowning Moment of Anything was his own death.
Pantha and Baby Wildebeest had received hate and ridicule for being "awful '90s characters" from various fans, although many fans decried their deaths in Infinite Crisis.
Flamebird. After the first Crisis, the original Batgirl no longer existed and Barbara Gordon was deemed to be the original. When Marv Wolfman and George Perez decided to revamp the Titans West team for the Post-Crisis origins of the Teen Titans, Betty Kane was reintroduced as Mary Elizabeth ("Bette") Kane, now with the codename Flamebird and a Valley Girl with a strong desire to get the affections and praise of Nightwing in any way. As Wolfman had no love for the Titans West save for Lilith and Changeling, the portrayals of the revamped versions, ESPECIALLY Bette, earned them spots high on the Titans "Scrappy" list. Flamebird wound up as a Butt-Monkey-type character for years to come, even though some writers attempted to make her seem more interesting through "depths" in her origin (stating her physical prowess and skills that rarely seemed to be reflected). Geoff Johns started a more streamlined take on the character in the Beast Boy mini-series, and it seemed that Greg Rucka was attempting to revise her into a much more competent heroine. The New 52 pressed the Reset Button via the Batwoman series, as Bette now lost most of her established history (and previous upgrade), making her come off as being nearly Too Dumb to Live and get mutilated by an enemy. She's later appeared to have gone back on track to a darker and more serious revamp in her costume, but time will tell if this change is successful.
Golden Eagle was initially hated for being a shoe-horned attempt to give Hawkman a sidekick and knockoff in the Pre-Crisis era, and was hated Post-Crisis for being a slacker surfer-type guy who'd only fight if it could get him women and attention. He got a little sympathy after being killed off, but after Jimmy Palmiotti and Justin Gray retconned his death and revealed him to be a Jerkass-type villain with a grudge against Hawkman, fans had new reason to despise the guy (or the direction he was taken in).
Cassandra Sandsmark, Wonder Girl; it didn't help that Cassie was mostly pushed as nice à la Donna Troy by writers, when in truth she came off like a raging Alpha Bitch after her boyfriend's death. Its worse when you remember that she started out as her schools lovable geek. Once Conner returned to the series (before the reboot), you think she wouldn't have had much reason to keep lashing out at her teammates, but some writers felt differently. Under Johns' (ironically) and others' pens since Conner's return, she had been portrayed positively and having gotten over her grief. But other writers, especially in the case of Felicia Henderson, had continued to portray her as an angry shrew, who even goes as far as to treat her back-from-the-dead boyfriend like crap (eventually leading to their breakup). Her New 52 version has similar controversy, but is also hated for being a thief, being overtly sexualized and having her connection with Wonder Woman only recognizable to readers of Wondy's book (she's the daughter of Diana's half-brother, i.e. the niece of Wonder Woman, though neither of them knew about it for the majority of New 52 Cassie's use). Once the New 52 Teen Titans series ended, she and it were never mentioned again beyond Broad Strokes in regards to the titular team.
Prysm, a member of Dan Jurgens' volume 2 team, isn't very liked by some classic fans due to coming off too naive and stereotypically feminine, spoiled, and her visual appeal mostly coming from the fact that she was nude all the time.
Fringe from the above run is also hated, for lacking personality and never being as developed. Unlike Prysm, it's hard to find fans that can tolerate him.
Minion from Wolfman's New Titans is either hated or ignored by most fans due to the fact that he came in during a Dork Age, and that he seemed to be pushed in as a cool new teenage character but lacked interesting traits.
Bombshell was widely disliked by a number of fans during her brief tenure on the team. She was criticized for having very little personality and was accused of trying to ape the characterization of the recently departed fan favorite Ravager. The fact that she was a Motor Mouth and a Jerkass didn't do much to help her standing with fans.
The DEOrphans, a group of metahuman kids from the DEO, were hated even more than the unpopular Titans. This was because they got in the way of the Titans' screentime and that they were simply useless at fighting or doing much to advance the plot. Their presence also caused the "Epsilon" arc to be heavily rewritten, and a bunch of other planned stories had been thrown out.
Terry Long, for being considerably older than Donna Troy, coming off as creepy, and his tendency to make blatant passes at her friends. (Bonus points: he looks an awful lot like Marv Wolfman.) He actually became even more of a Jerkass in the '90s, before he was killed off in John Byrne's run of Wonder Woman.
The rest of the Team Titans besides Terra II (and at the very least Metallik, a minor sub group composed of an all girl rock band who controlled a giant robot). While they've come to have some nostalgic fans in recent years, the general Titans fanbase widely loathed them and still looks down upon them, as they were a publicity stunt used to shake up the book and came along with other plot twists that ran the title into the ground. The common criticism is that the characters relied on dated '90s and 20 Minutes into the Future stereotypes. Out of the group, Mirage is most criticized for committing rape by fraud (in disguising herself as Starfire and tricking Nightwing into having sex with her). The later writer of the "Team Titans" title had even wanted to kill off Mirage due to her unpopularity, but this was averted. Killowat and Prestor Jon also became loathed, both for becoming increasingly assholish to their teammates and especially because of the ignorant racist comments that the former made about Mirage being "pretty for a dark skinned girl".
Deathstroke's Titans team qualifies for this status as well. They are even more so ignored than Fringe and Minion, who are at least mentioned in nostalgic regard when discussing the past Titans team, whereas Slade's team of mercenaries is completely ignored save for when someone is mentioning a member that was already a Titan (Roy, Osiris) or associated with the group (Cheshire, Deathstroke). Most fans wish to pretend Eric Wallace's run on the book didn't exist because of the extreme levels of gore, stilted dialog, and the book's starting point being Ryan Choi's prolonged murder. Even a gracious creator like Gail Simone couldn't defend the Villains for Hire special that started this run, and she almost never badmouths any comic.
Coming off that, the most reviled character in this team was by far Cinder, who was a brand new character created for the series. Fans viewed her as a personification of every poorly handled rape and abuse trope in comic books as her trauma and suicidal tendencies were pretty much all there was to her. Eric Wallace tried particularly hard to get fans to sympathize with her by having her admit she thinks she's a bad person and her forming a small bond with Tattooed Man, but it only felt forced. Not to mention how utterly selfish and stupid she is, killing Ryan Choi in exchange for killing higher profile rapists, being unable to talk about anything but her suffering and letting Nursery Cryme (a serial child molester) go free because she didn't think out her plan to kill him. Whereas every other member of Deathstroke's group have at least some fans by themselves, Cinder has none.
The New 52 version of the Joker's Daughter. The original Duela Dent may not have had a huge fanbase, but almost no one likes the new one and fans of the original absolutely loathe her. The complaints center around how unnecessarily "edgy" her design is, being some random girl who was into self-mutilation, found the Joker's cut off face, started wearing it as a mask before having it surgically grafted onto her face, and leading some weird underground cult. What didn't help her case was how shoehorned she was throughout the New 52, first appearing in Catwoman before getting her own one-shot comic and then becoming part of the main cast of Suicide Squad where that series fans loathed her as well, for being there solely to share the Conflict Ball with Harley Quinn. She was quickly shunted off, and next appeared in Red Hood/Arsenal, written by the much hated Scott Lobdell. Fans of the original Duela Dent are praying she's not the same person as the Joker's Daughter.
Wonder Woman: Jason, the brother of Diana introduced in James Robinson's run. Disliked from the start due to being the artifact of the New 52 era (after the past year had been spent largely erasing the N52 version of Wonder Woman from existence), his hatedom only increased when he actually debuted. Much of the hatred includes his extremely bland design that amounted to basically a male version of Diana in a shirt and pants, his only notable personality traits being that of an unlikable frat boy who trashes his own sister's house just days after finally meeting her, then complains about having to clean up, a nonsensical backstory that he keeps framing as a Dark and Troubled Past despite the only remotely bad thing being that his adopted father left him after he was old enough to take care of himself, being stupid enough to take Grail at her word, and, despite being completely uninteresting, he quickly turned into a major Spotlight-Stealing Squad who constantly applied New Powers as the Plot Demands. By the time the "Children of the Gods" arc was done, fans were clamoring for him to be killed off.
Young Justice: Slobo/Lil' Lobo was a polarizing figure among fans and writers. The final issue of the series saw him transformed, turned into a living statue, and he has not been seen or mentioned since. DC editor-in-chief Dan DiDio reportedly despised the character, and claimed that he nearly ruined the original Lobo.
Few fans of Annihilation: Conquest liked Wraith, a new character introduced in a tie-in miniseries. In an arc full of lesser lights and very humanized characters, a motorcycle-riding uber-Space Elf with ill-defined darkness powers and a fantastically wangsty backstory stuck out like a sore thumb. After four issues of fans wondering how a twelve-year-old's fanfiction got shuffled in with the Annihilation scripts, Wraith proceeded to appear only as a supporting character in Conquest itself, and never appeared again afterward.
During the Busiek/Perez run, new character Triathlon wasn't held in very high esteem among the fandom. Some of this was due to being a member of a Church of Happyology, some of this was due to his being foisted on the team by politics, but mostly due to his acting like a Jerkass to the established characters people actually like. After he left the group, any enmity against him was largely forgotten — until he mercilessly killed Crusader at the end of Secret Invasion.
Wonder Man earned this reputation back in the 80's, when he was a member of the West Coast Avengers. The fan reaction to the infamous storyline where he tried to break up Scarlet Witch and The Vision so that he could date the former earned him the ire of a number of readers.
From Fantastic Four, there's Franklin Richards, the son of Reed and Susan Richards. Not only is he a frequent kidnapping victim, which in itself would probably make him a Scrappy, but he's also an all-powerful Reality Warper who is undoubtedly one of the most powerful characters in the Marvel Universe. But even that has potential, as seen with characters like Superman, exploring what to do with that power and how much it weighs on people. But no, all he does is pull retcons and marketing gimmicks for Marvel (the much loathed Heroes Reborn) and that's when his powers aren't suppressed. And when that's not happening, his entire character is being the "normal" person, but in a bland, having pretty much no character way. It doesn't help that Valeria Richards, Franklin's younger sister, is much more liked, due to being much more intelligent, fitting in with the high-concept stories more, and having an interesting relationship with Doctor Doom. Franklin was Rescued from the Scrappy Heap for some during Jonathan Hickman's beloved run, where Franklin was a focus. His adult counterpart was given an actual match for his powers, and his scenes with Galactus in particular are liked by some, while others consider it to be just another Ass Pull. Franklin himself began being developed into a character who had daddy issues because he is of average intelligence, and what was focused on was that Franklin had a big imagination in comparison to his sister Valeria's intelligence.
However, pretty much immediately after Hickman's run ended and Matt Fraction's run began, he reverted to his entire character being "the kid" of the group. It didn't help that Valeria also became that kind of character, drawing attention to it.
Dan Slott's take on Franklin has proven immensely unpopular. He remains a central focus of Slott's run, but has been heavily flanderized. When he's not Plucky Comic Relief, he's angsting. He has been nerfed yet again. Only this time, much of his pagetime is spent acting like a jerk and complaining about his power seep (despite previous incarnations of the character showing much more maturity over this very issue.)
None of the Marvel Scrappies above, however, compare with reporter Sally "YouTube is more important than personal liberties" Floyd. Yes, she actually expressed that viewpoint, and what's more Word of God says the reader was supposed to agree with it. There is even a list for the Top Ten Reasons to hate Sally Floyd◊. Paul Jenkins seems to have a flair for creating these, actually, as he's also coughed up the ridiculous and biology-defyingSpider-Man villain The Queen and everyone's favorite Invincible Hero, The Sentry (though, to be fair, the Scrappification of this character only came into full when other writers began using him; Jenkins has nobody to blame but himself for the disastrous Fallen Sun, however).
Aunt May, to those who feel her character has become The Artifact. As Peter Parker is now an adult, a grandmotherly figure seems more unnecessary. It doesn't help that his attempts at saving her life caused the most hated storyline in Spider Man History. It also doesn't help that both of her deaths were well-received, especially the first, an undoing them so she can be a grandmother to Peter is seen as really unnecessary.
The first Madame Web, mainly because she gave a lot of vague prophesizing and warning without ever actually helping Spider-Man with the threats she keeps saying are just around the corner. It wore on people's nerves after a while. Even in-universe Spidey doesn't like her all that much.
Carnage has been around for quite some time, and while he does have his fans, a sizable chunk of the fanbase really hates him and always has hated him. When he first came out, he was widely decried as a Joker copy minus any of what actually makes the Joker a good villain. His near-total lack of meaningful character development has not helped his cause. Being a violent nihilist who devotes his entire existence to murdering as many people as possible may have worked just fine in the Nineties, but as comics began to move away from that type of thing, he did not change one bit. His tendency to go around inflicting The Worf Effect just to show how much of a threat he is also doesn't tend to go over well. Marvel at least seems to be somewhat aware of how widely disliked he is and periodically does things to try and re-establish him, but none of those attempts have ever actually addressed the core issues of why fans hate him. It says quite a lot about Carnage when by far his most popular appearance in years was in AXIS... a comic whose core gimmick was heroes and villains being turned into the opposite of their former selves. In fact, usual Carnage is disliked by so many that fellow Scrappy The Sentry briefly managed to briefly get himself off the list by flying Carnage into space and ripping him in half.
A lot of the villains introduced during Brand New Day, like Freak or Paper Doll, were rather hated by fans due to replacing many of Spidey's established foes as well as the new villains established during JMS's run. At the same time many of said villains lacked the traits that made the old bad guys likable or cool. The only exceptions to this are Mr. Negative and Overdrive, who have managed to establish themselves as lasting and worthy new additions to Spidey's Rogues Gallery.
Michelle Gonzales, a token love interest for Peter from the BND era. Michelle is a violent bully who wound up becoming Peter's roommate when Vin went to prison, and regularly insulted, abused, and humiliated Peter.
New "hero" Alpha due to basically being the antithesis to everything Spider-Man stands for (has zero responsibility, wastes his gifts, has an ego the size of a mountain, etc.).
Carlie Cooper's portrayal resulted in a massive backlash from fans.note Joe Quesada, the mastermind behind One More Day, had originally intended to resurrect Gwen Stacy during the event, but as her death was too important to Spider-Man, he was turned down and conceived Carlie, named after his daughter, instead. Originally it was more along the lines of Replacement Scrappy for MJ, but it escalated when everyone, from past girlfriends to best friends, kept telling Peter how 'right' she was for him because she's his 'intellectual equal'. It was REALLY not helped by the fact she would get mad at Peter for the stupidest things, was pushed as a Woobie because her hero cop dad supposedly died only to be revealed he wasn't a hero and wasn't dead, act like a hypocrite, amongst other problems. She's also received ire for having similar characteristics as four of Peter's past love interests: troubles with father (MJ), Nerds Are Sexy and attempted Adorkable (Deb Whitman), loves Peter for him (MJ, and an invert of Black Cat), is old friends with Harry Osborn, a tsundere, and Peter's 'true love' and perfect girl (Gwen). You could make the case that the writers are trying to evoke Gwen Stacy in her character, but in the end comes off as a lot like Lana Lang in Smallville. In the aftermath of Spider-Island, she was demoted to a supporting cast member without romantic interest in Peter. However, in Superior Spider-Man, the hatred for her increased tenfold, with Carlie somehow being the only one who investigated why Peter was acting massively out of character. She discovers what happened by doing what can be considered the barest minimum of detective work. Again, fans were not amused at Carlie getting such an easy win, and rejoiced when she was Goblin'd... only for it to inexplicably not work on her, and her alone. Fortunately, after that she left the Spidey books entirely.
Cindy Moon aka Silk was this when she was first introduced (she got seriously Rescued from the Scrappy Heap when her ongoing came out though). Created via retcon as a girl who was also bitten by the same radioactive spider as Peter Parker, Silk was a hugeCreator's Pet and Replacement Scrappy who was introduced to be both Peter's new love interest and crime-fighting partner, whose debut storyline also featured the highly controversial FaceHeel Turn of Black Cat. Besides her powers being essentially 'Spider-Man's only better', she also had Strangled by the Red String as an actual part of her powerset, as she produced pheromones that made herself and Peter unable to stop trying to make out when together, something that raises serious questions about consent. All of this combined with her It's All About Me disposition, and her inexperience in superheroingnote leading to the deaths of Last-Stand Spider-Man and Spider-Assassin during Spider-Verse, during which she was a hugeSpotlight-Stealing Squad made her heavily disliked...and yet, for some reason Marvel decided to give her an ongoing series.note Fortunately, the latter turned out to be a blessing in disguise, as the book quickly retconned out her pheromone powers and gave her heavyCharacter Development, put focus on her anxiety and depression while downplaying her Jerkass tendencies and thus transformed her from a selfish idiot into an Adorkable but well-meaning rookie. Her relationship with Peter was also changed into something more platonic, and her book gave Black Cat much better attention than Silk's aforementioned debut story did, with Cindy and Felicia developing a very well-liked dynamic, and she became something of a Morality Pet for J. Jonah Jameson. By the time her run finished its course, she was completely unrecognisable from the girl people were decrying back in Spider-Verse.
All of the Inheritors except Morlun and Karn. While some dislike Morlun, most are ambivalent towards him and he had a mysterious and scary vibe that made him a decent addition to the Rogues Gallery. The others on the other hand are generally considered boring and annoying at best, and ruin Morlun's style at worst. Two stand out in particular:
Daemos, Morlun's bigger, dumber, eviler brother. Mostly for having very few personality traits beyond... "big, dumb, and evil." Also because he killed MC 2 Peter Parker and Spider-Man Unlimited.
Morlun's father Solus too, for being an Invincible Villain capable of killing Captain Universe!Spider-Man with little effort, despite the latter being a Physical God.
The Sentry was originally received well enough (largely because of his interesting origins and his jaw droppingly cool fight with the Green Scar Hulk), until World War Hulk or Secret Invasion. Unfortunately, Bendis got hold of him and turned him into Norman Osborn's pet killing machine with the mentality of a child, and gave him more powers than Silver Age Superman. This, combined with the fact that writers kept changing Sentry's origin and his relationship to the Void (The Void is Sentry's split personality! The Void is the real Bob Reynolds, who was a druggie! The Void is the Angel of Death!), meant that eventually every reader had stopped caring about who the Sentry really was and just wanted him to go away. Even then, his "interesting" origins were a cause for a broken base considering they consisted of him stealing a random vial that somehow made him strong enough to fight off Galactus. That same one that much more technologically advanced Galaxy spanning empires like the Skrulls can't stop but a much more primitive lab's random vial is just the trick.
Ultimate Marvel has their take on Deadpool, primarily amongst fans who had come in from the original Marvel Universe. 616 Deadpool, while having originally been created as basically a rip-off of Teen Titans villain Deathstroke the Terminator, is well-known in current pop-culture for going so deep into Chaotic Stupid that he emerges in the deepest part of Chaotic Awesome, glorifying in surreal, bloody-yet-wacky antics and lots and lots of fourth wall breaking, perhaps being the best known comic version of the Fourth-Wall Observer. 1610 Deadpool, on the other hand, is a horrifically mutilated cyborg; not only is he an active participant in a mutant-phobic country's sick program of kidnapping mutants from other countries and then hunting them down to slaughter them on national live television for entertainment, he's fully aware that they are usually innocent. He just hunts them anyway because he finds it fun. In other words, Ultimate Deadpool is crazy, but in a sick and horrifying way, whereas Mainstream Deadpool is pure Crazy Awesome, and so the fans of the original revile the Ultimate version — the closest Ultimate Deadpool has come to being Rescued from the Scrappy Heap is when he appeared as a Composite Character (Ultimate Marvel appearance and rough MO (still runs a reality show), Marvel Comics personality) in Spider-Man: Shattered Dimensions.
A notable example is Maggott. A mutant with a very disturbing power who spoke in thoroughly annoying South African slang and was hyped up as being awesome, amongst other complaints. Fortunately, they got rid of him after a short-but-not-short-enough amount of time. And now he's dead.
The third man to go by "Thunderbird", Neal Shaara, by virtue of having absolutely no right or reason to use that namenote He originally was supposed to be called Agni, after the Vedic fire-god, but that was nixed by editorial for sounding too much like "acne".; the original Thunderbird and his brother were both Native Americans with superhuman strength, durability, and speed. Neal is/was an Indian with fire/energy powers. Having the popular Psylocke dump the also well-liked Archangel for this guy also rubbed people the wrong way.
More than practically any other teen X-Men character, Ink from the very short-lived Young X-Men series was hated by many fans. The fact that the writer went to extreme lengths (like ya know, giving him the power of Phoenix) to make him seem important did not go over well with fans, and he also had the stigma of being a human rather than a mutant. Being a Jerkass and bizarrely ending up with Emma Frost in a Bad Future also didn't help.
In second place would be Icarus, for his Wangst, his bringing up his dead girlfriend (whom he'd only dated for a week) every other appearance, and the fact that he ends up trusting an Obviously EvilSinister Minister and getting himself and many of his friends killed in the process. A panel of his dead body with a ridiculous expression on his face has become a meme in the fandom. His wangst is especially bad when you consider that the rest of his team actually have legitimate emotional problems. He even compared the feeling of losing the aforementioned girlfriend to losing everything, even though he has a supportive mother as well as brothers and sisters who are also mutants and attend Xavier's with him, and is generally not in any of the conflicts at Xavier's. What's worst is that he said this to Surge, whose father basically disowned her because of her powers, and whose mother is too afraid to stand up to him. Icarus already had two strikes against him, having been created by the fan-reviled Chuck Austen and introduced in what's generally considered one of the worst X-Men stories of all time. His Wangst didn't so much tip him over the edge as throw him bodily off of it.
Very difficult to believe now, but Kitty Pryde started out like this. Her introductory story was fine, but some fans thought that Claremont had no idea what to do with her after John Byrne left (it did not help that Byrne's final three issues were crowning moments of awesome for Kitty). Her acceptance became general in the Brood arc (which also introduced Lockheed, her constant companion) and with the story "Professor Xavier Is A Jerk!" which was fittingly about Kitty Pryde justifying her membership of the X-Men.
Scarlet Witch. What was interesting was that before House of M, she was a pretty popular character, particularly among romance fans for her marriage with Vision, those with mental illness, and female comic book readers. A big part of the hate comes from the fact that, in order to use her again, writers had to retcon that she was being manipulated by Doctor Doom at the time (we'll ignore how little sense that makes) to justify the Avengers forgiving her, and now anyone still angry at her tends to be painted as unreasonable (including The Vision, her ex husband, whom she murdered, and is treated like an insensitive Jerkass for being angry about it), since she wasn't technically at fault. Never mind that in the same comicCyclops was talked about like he's Hannibal Lecter despite the fact that his actions actually were the result of being controlled by another force, which the Avengers know because that's why they started that Conflict Ball to begin with. While Wanda was retconned into being possessed to excuse her actions, Scott was shown from the beginning that this was the case, and yet he still gets treated like shit. The Double Standard just pisses fans of the X-Men off. Her well-received solo run, however, succeeded in having her Rescued from the Scrappy Heap and her portrayal in the Marvel Cinematic Universe brought old and new fans to check out her more well-received pre-House of M storylines.
The Inhumans, never the most popular of Marvel's character groups, have steadily become this following the Terrigen bomb - the fact that they were taking the place of the X-Men, both symbolically (young people with new powers popping up everywhere, being found and guided by a senior team) and as a species, what with the Terrigen cloud giving mutants 'M-Pox', a knock-off of the Legacy Virus.note Not helping things was the Executive Meddling where Ike Perlmutter orchestrated the push of the Inhumans in the place of the X-Men because at the time, the X-Men's film rights had not been regained by Marvel yet. The Inhumans' general self-righteousness, the fact that they treated an attack on the Terrigen cloud by the X-Men as an excuse to respond with lethal force (as is pointed out, without the Terrigen, the worst that happens is some people don't get powers. With it, mutants are on the verge of extinction), primarily against Scott or rather, Emma Frost's projection of him. Oh, and then they depict him as Mutant Hitler - needless to say, the X-Men's revenge in Inhumans vs. X-Men was one of the few parts of it that was widely applauded. Really, it isn't so much a matter of trying to imagine why they're so disliked, but why anyone would like them in the first place.
Beast has increasingly become this since Schism, becoming increasingly arrogant and self-righteous as he takes increasingly reckless decisions (bringing the O5 to the future being just one), then when called out for them by all of the X-Men, retorts that they can't possibly be smart enough to understand what he's doing and thus to judge him. Unsurprisingly, this does not make him popular.
Judge Dredd: Walter the Wobot. He was fine, until they decided to give him a speech impediment. Do you have any idea how many 'r's are used in the average English sentence? You will after reading his dialogue, as every single one turns into a 'w' that drills into your soul like a misshapen bullet. And of course, he worships Judge Dredd. And for some reason Dredd puts up with it! Walter eventually gets his own feature.
Drago Wolf, the Wolf Pack Freedom Fighter traitor. No one likes the misogynistic bastard, not even current writer Ian Flynn (who has gleefully stated he only brings the guy out whenever he wants him thrashed by the good guys). The fact that he's a despicable coward whose only claim to fame was tricking his former girlfriend into playing the patsy to a murder/frame-up in a totally illogical and scientifically impossible way, and joining an anti-Freedom Fighter team that he's contributed nothing to, during his tenure there doesn't help his cause, any.
There's also Tommy Turtle. He was originally a one-shot character that revealed that he had given Sonic a life lesson when he was younger and had performed a Heroic Sacrifice to save Sonic from an ambush. However, he ended up returning after a Time Skip, healthy, whole... and attempting to replace Tails and Rotor. When Ian Flynn took over, he compiled a list of characters in the series and arranged them in popularity, finding out that Tommy was STILL at the bottom. He's promptly killed off during Ian's collection of Author's Saving Throw.
From The Walking Dead comic, there's Lori. Abandoning her husband without even a note, cheating with his best friend less than a month later, confronting a very angry farmer, confronting potentially violent inmates, being completely worthless in battle, having no other abilities whatsoever, and never bringing anything to the table other than bitch and whine, she's even more of a Scrappy when compared to the far cooler and tougher Michonne or Andrea.
In the comics, Orube took flak for a while, some of it perhaps because of fears that traditionally, new additions to longtime Five-Man Band stories tend to be bad ones. Most of the hate died down eventually though.
We is also widely hated, mostly due to being a completely pointless character (and being made the Series Mascot despite being introduced so late).
