Happened to Nightwing in JLA-Task Force. He wasn't loathed by the fans, he was loathed by his team members in canon.
During Grant Morrison's JLA run Huntress is that to Batman (she was brought in as a last second replacement for Connor Hawke). He eventually kicks her out after her continued disregard for rules leads to her almost executing a defeated villain.
And since we brought him up, this happened to Green Arrow Connor Hawke. Even though fans had warmed up to him, many writers would treat him poorly as he wasn't Ollie. For example, he was given a disease that prevented him from holding a bow again, something that seemed to even irritate people who weren't fans of the character. With the New 52, he and a bunch of Legacy Characters that apparently weren't "iconic" enough were relegated to Earth 2. In that universe, there doesn't seem to have ever been an Arrow family of characters, and Connor is the only one, and goes by Red Arrow, Roy Harper's old name from his Justice League days.
Hawkgirl Kendra Saunders is an interesting case. Fans generally seemed to accept her and didn't mind so much that she wasn't truly Shiera. They had the same soul, after all. However quite a good number of fans were pissed when Kendra was killed off in Blackest Night and Sheira was brought back in Brightest Day, and Kendra was set up as the Hawkgirl of Earth 2 in the New 52.
The Sandman: When Daniel replaces Morpheus near the end, this reaction is inevitable and instinctive for readers and characters alike. The shock is gently muted as the final arc deals with the other characters - notably the raven, Matthew - coming to terms with the replacement. This openness, combined with Daniel's dignified humility and the knowledge that he had been carefully hand-picked by his predecessor, helps the reader to accept him.
It probably helps that the series ends at this point, since one of Daniel's positive qualities is the absence of some of the original character's inner turmoil. He is an easier character to like, and we never really see him in action enough to compare how he drives the plot.
It's much easier to accept if you came to the series after its completion and know that it is essentially about the downfall of Morpheus.
The Flash has had issues with this very similar to Green Lantern mentioned above. At the end of Crisis on Infinite Earths, Barry Allen made a Heroic Sacrifice, and Wally West, then the Kid Flash, became the Flash. Wally was not well received at first, whether due to his being young, a Jerkass, or the fact that he was less powerful (he lost a lot of his speed during the Crisis and didn't get it back for years.) While Wally grew into the role and gained acceptance, Barry kept appearing in one-off stories set in the past, time travel stories and one notable "fake out" event as well as a short lived TV series keeping his fandom alive. When Barry came back after 24 years of being dead, fans are split.
But when Bart Allen had his turn as The Flash, fans were much more in agreement about their loathing of the character due partly to the Wangst, partly due to his being artificially aged to shoehorn him into the role, but mostly because the character lost his Fun Personified sense of humor and cheerful demeanor.
Barry is getting this more now than ever since in the New 52 Wally was not only never Flash, but never even Kid Flash. For years, he didn't even exist, and the role of the first Kid Flash was given to the second Kid Flash Bart Allen. Even fans that don't like Wally seem to feel that this was a low blow to his fanbase.
Many people dislike Jason Rusch (Firestorm), and Ryan Choi (The Atom) due to the killing off or running off of their predecessors. However, when Ryan Choi was ignominiously killed off, people had gotten over that he wasn't Ray Palmer, and now viewed Ray as this. After a pretty massive racial controversy that got coverage on some non-comic sites, DC retconned Ryan's death during the Flashpoint series and now he is the sole Atom in the New 52 continuity, with Ray being regulated to a scientific adviser for the S.H.A.D.E. organization.
An odd in-universe form of the Replacement Scrappy status of Ryan Choi came in Dwayne McDuffie's Justice League of America run, where Batman, Superman, and Wonder Woman considered asking him to join. Superman is reluctant on the subject, saying that he doesn't want to replace Ray and would prefer to keep the position of the Justice League's Atom open in case he came back.
The New 52 continuity not only retconned the death of Ronnie Raymond (the first Firestorm who was killed to make way for Jason) but now made it possible for both he and Jason to become Firestorm at the same time, alleviating some of the tension between the characters' respective fanbases.
Holly Granger (as the second (or third?) person to bear the title of "Hawk") also got this reception by fans, though it didn't help matters that writers had no clue what kind of personality she had, or bothered to flesh out a personality or backstory for her to begin with. Being retconned in as "only child" Dawn Granger's sister and an usurper of Hank Hall's Hawk powers only rubbed the salt in further for her hatedom. They rejoiced as Hank Hall was eventually brought back to life while Holly was killed off, and she appears to no longer exist at all in the New 52 continuity.
In-universe, Jakeem Thunder was seen as this by a number of the original Justice Society of America members. Ironically, he never really received much negative treatment from the fans since his predecessor wasn't a character most readers were likely to be familiar with in the first place.
Batwoman was (and still is in some fans' minds) seen as one of these after she took over the lead female Bat Family role from the Cassandra Cain incarnation of Batgirl, who was moved out of focus. This was largely erased after she starred in a well-recieved, Eisner Award run of Detective Comics.
The fourth Batgirl (Stephanie Brown, formerly Spoiler) has been seen as this as well, due to her being a blonde Caucasian female who replaced one of the few Asian superheroes in all of comicdom (and the only female Asian hero to maintain a long-running solo series). (Oddly enough, Cassandra and Stephanie were Les Yay-riffic best friends in-universe and would probably take offense at this.) Steph would eventually win over a a number fans by being a really fun character. Though her book wasn't a smash hit (it had enough sales to be in the top hundred comics being sold, but not on par with usual Bat-books), she managed to win over a very vocal fanbase that protested heavily once she was removed from the role.
Both Stephanie and Charlotte Gage-Radcliffe (who later took on the identity of Misfit) both dealt with this from Oracle when they first attempted to take on the Batgirl mantle, with Oracle even slapping Charlie after she made a disrespectful remark about Cassandra.
The second Wonder Girl (Cassandra Sandsmark) is hated by some of the more diehard Donna Troy fans. Some even wish that she weren't a "blonde, white girl" so that she would be killed off easier for Donna to go back to the role. This is especially irritating since in the 90s, Cassandra was a much more friendly, likable character then the Scrappy people see now. Further made worse for Donna's fans in the New 52 continuity, where Cassie's new connection to Wonder Womannote Cassie is Diana's niece, the daughter of Diana's half-brother Lennox hasn't been revealed in-universe despite the relaunch occurring in September of 2011. And like Wally West, Cassie is nwo the first Wonder Girl, and Donna wasn't introduced until 2015, where she is now a darker, angrier reflection of Wonder Woman, a role Cassie already fills.
Her popularity decreased however, as Peter David was allowed to completely revamp the character in his own run on Supergirl. His Supergirl was actually an angel, created when the Matrix Supergirl fused with a human named Linda Danvers. His run, while making a number of references to the original Supergirl, touched on religious and supernatural themes. It was seen by many as a departure from the original character and the Superman mythos (although it's not like Superman hasn't dealt with magic and demons before). The situation was similar to the Cassandra Cain Batgirl (see above) in that despite her earlier problems Linda gained a sizable fanbase and the series ran for several years. Peter David finished the series with an arc that reintroduced the original Supergirl with the hope of turning it into a new series. Unfortunately it didn't happen and Linda was Put on a Bus, but it may have inspired the creation of the Supergirl that came after the next one...
And finally a new version of the original Supergirl, Kara Zor-El, was created supposedly just to get rid of the confusing origins of the previous Supergirls now that the Legacy Implosion policy was overturned. Although her initial appearances were promising (except for people who were upset with Linda's disappearance), she garnished significant hatred for being both Darker and Edgier and Ms. Fanservice. Not to mention the fact that her backstory on Krypton was Retconed with every writer she had. An Author's Saving Throw finally softened her character and clarified her history, which was mostly accepted by the fanbase.
At the same time as the Death of Superman arc, Batman also got a Replacement Scrappy in Azrael, who took up the mantle after Batman's back was broken. He went over terribly with the fans, but like Superman, the writers never intended, and the readers never believed, that Azrael would ever be a permanent replacement.
Like with the Bucky example above, averted entirely when Dick Grayson became Batman. The decision for both Bruce and Dick to act as Batman simultaneously is seen s a welcome third option. Some fans really didn't want him returning to his role of Nightwing.
Played straight with Tim Drake becoming the new Batman Beyond, replacing Terry Mc Ginnis. Terry is a pretty big Ensemble Dark Horse, and is synonymous with the Batman Beyond role. But Futures End ends up replacing Terry with Tim, and Tim gets to be the protagonist of the new, canon Batman Beyond ongoing. A large group of fans are not picking up the new series purely on the basis of it not starring Terry.
Then played straight again towards the post-Batman: Endgame Batman, James Gordon. A lot of the hate towards this Batman is because he spends a lot of time running around in Powered Armor and ramping up the Batdickery by attempting to arrest or kick out any costumed character who wanders into Gotham. At the same time, his entire character essentially becomes "cop", and many just find him boring. It says something that the most-liked scenes from his run involve the possibility of Bruce Wayne returning to the role.
Deathstroke's team of "Titans" when Titans was remade into a series about Slade's mercenary team stealing the Titans name after the actual, adult Titans had disbanded following Justice League: Cry for Justice and Blackest Night. The run immediately got off to a bad start by killing off Ryan Choi in an extremely graphic and dragged out manner just to show how "dangerous" this new team was, which landed DC a number of accusations about inter-company racism; Ryan's creator Gail Simone actually broke her legendary politeness to say how much she hated how he died. A few years later, DC released Convergence with two miniseries, Convergence: The Atom and Convergence: Titans meant to specifically address and undo the damage this run on the book did. Added to the accusations about Ryan's death were:
The over saturation of blood and gore.
Arsenal joining the team right off the heels of the much loathed Rise of Arsenal miniseries. Cheshire emotionally blackmails him into joining by holding Lian's death against him, and he conspires with her to kill Slade when they get the chance. Roy started appearing more and more psychotic as his drug addiction worsened, and then readers felt especially angry when he willingly accepted a vial of Bliss from Slade, with Bliss being a drug that is literally made from children. Author Fabian Nicieza had to specifically state that the Roy seen in Convergence was pulled before he fell as further down as he did in the sewer of Deathstroke's team.
Osiris gradually going from being the Token Good Teammate to a Spoiled Brat psychopath who got so bad even his own sister was repulsed by his actions. His inclusion in the title was the only reason the book was connected to Brightest Day (in that Osiris had to restore Black Adam and Isis after they were Taken for Granite), but said connection pretty much amounted to nothing in the series itself and the main Brightest Day book.
Everything about Cinder's character. A suicidal rape victim whose debut included her murdering a man by burning off his penis and setting him on fire using her vagina. We're being serious here.◊
Speaking of the Teen Titans, the New 52 series and its team is hated by pretty much all of the Titans fans combined, even the fans of the characters. The team is hated by fans of the original Titans for specifically being the first team to call themselves the Titans, meaning the original team never existed - indeed, only Dick Grayson and Roy Harper initially existed in the New 52. Fans of the team that is the basis for the New 52 team hate it for the changes it made to their characters, namely making Cassie (more) of an angry asshole, the complete change to Bart Allen's character and finally going 100% in making Tim Drake a mini-Bruce Wayne in terms of his obsessiveness.
When DC decided to kill off underdog fan-favorite Blue Beetle (Ted Kord, himself the second character to use that name), fans were enraged. His replacement, Jaime Reyes wasn't really disliked by people, but fans hated DC's callous treatment of Kord and the Character Derailment of him into a laughing stock for the other heroes, which came off as Character Shilling for Reyes.
Poor Ben Reilly who was disliked because of the revelation that he was the "real Peter Parker" and that the Peter fans had been reading for twenty years was really a clone. After the huge fan outrage Marvel quickly backtracked and reversed that decision.
Kaine, another Spider-Man clone, was a less explicit form of this trope. He wasn't really a replacement villain for an old one, but his Bridge Drop of Doc Ock solidified him in fans minds as an unwanted loser who was biting off more than he deserved to chew in casually offing a beloved, classic Spidey villain with decades of continuity to back him up, and prompted cries for Doc Ock's resurrection and Kaine's axing. Basically, Kaine managed to become a Replacement Scrappy for a character whose role he wasn't even taking over. Thankfully, Dr. Octopus was later resurrected, and Kaine performed a Heel–Face Turn, saving him from the scrappy heap.
Also, as pointed out in the Spider-Man Wild Mass Guessing page, all of her Informed Attributescome from other love interests like Mary Jane, Black Cat, and Deb Whitman. Now people are hoping she'll "be like Gwen Stacy" and die.
Following the events of Spider-Island, Peter and Carlie broke up. However, Carlie is not completely out of the picture and remains friends with Mary Jane, as well as serving as Spidey's occasional ally on the police force.
Any Hobgoblin that isn't the original, Roderick Kingsley. Kingsley is a fan favorite for his brilliance, likability, and high success rate. The others? Not so much:
Jason Macendale was an unlikable, one-note Blood Knight and former C-Lister who was almost offensively incompetent. The original Hobgoblin was a powerful mastermind feared by all; Macendale was so pathetic that even the writers came to hate him. He was killed off and occasionally gets mentioned again, but never with kindness.
Phil Urich was seen as only slightly less of a loser. He had a better success rate, but his motive (trying to impress a girl who was blatantly uninterested) was a complete joke and he only got the identity by cheapshotting the original and stealing the gear. It was revealed that the original Hobgoblin was alive and well, and a major storyline had him confront and utterly trounce the pretender.
Doctor Octopus has become a major one among fans after a recent arc concluded with him taking over Peter's body and becoming the new Spider-man, while Peter dies in his, leading up to the new series Superior Spider-Man. This cooled off considerably once it was revealed that both their minds were in Peter's body... only to flare up again when Otto erased Peter from his mind and took full control.
Toward the end of the series Word of God from Dan Slott revealed that this was wholly intentional; the point of the storyline was to demonstrate how fans take Peter for granted by replacing him with the worst possible substitute. It is Peter, not Otto, who is the "Superior Spider-Man" of the title, as admitted by Otto before he voluntarily erases himself and gives Peter full control once more. The storyline still has some haters, though, mostly due to Arc Fatigue, with some fans feeling everything the series accomplished could've been done in a single arc.
During Kevin Smith's run on Daredevil, Quentin Beck, the original Mysterio, committed suicide. Some years later, when Smith got the opportunity to write a Spider-Man story, he gave the Mysterio costume to an original creation, Francis Klum, who Smith tried to play up as a misunderstood victim who was pushed into villainy after Spider-Man beats him so badly that he's left permanently disfigured. He was so poorly received that Marvel ended up bringing Quentin Beck back from the dead and having Klum implicitly killed off.
This may have been a factor in the failure of Robert Kirkman's very well-written Irredeemable Ant-Man series. At the time there were two Ant Men; Hank Pym, the original Ant-Man, and Scott Lang, the second to use the name. Irredeemable was about a third, brand-new character, Eric O'Grady. It didn't help that Eric O'Grady starts the comic as an unlikeable dick (he gets better) and fans were still pissed about Brian Michael Bendis having dropped a bridge on Scott Lang. This seems to be decreasing with time as later books (like Thunderbolts and Secret Avengers) have furthered Eric's Character Development resulting in him becoming a snarky and likable Jerk with a Heart of Gold. In fact he seems to be slowly becoming an Ensemble Darkhorse, so much so that fans were enraged when he seemingly died in Secret Avengers.
There are a lot of fans who hate any character in Runaways who took the spotlight after Gert died. No one gets this more than Klara Prast, for being the only character not created by Brian K. Vaughan, for not having a supervillain parent like every other member of the team, for being introduced in a story generally regarded as a Bizarro Episode, for freaking out over the team lesbians, for not having an origin for her powers, for having a punny name...
Lampshaded, when Molly remarks that the team eventually gets used to the new recruits by the time someone else dies.
And then there was the new team introduced in Secret Wars (2015), which was almost entirely unconnected to the old team and made up of alternate-reality versions of established characters like Amadeus Cho and Jubilee. Originally advertised as an ongoing series but turned out to be just a four issue mini. It's unclear if this was by designnote Most SW tie-ins were advertised as ongoings even in cases where it was fairly clear from the beginning that they won't be, like Years of Future Past. or because it became one of the lowest-selling SW tie-ins.
Averted with Captain America. When Cap's old sidekick Bucky took the mantle after Steve Rogers' death, his portrayal was done successfully and he was widely accepted by the fans. To the point where Steve Rogers' inevitable return disappointed many fans that had grew accustomed to BuckyCap. Possibly because of this, even after Rogers came back, he declined to take up his shield again and let Bucky continue to be Captain America for a while.
Similarly, just from pre-publication press releases and the like, The Falcon becoming the new Captain America in 2014 is not particularly hated by anyone. While some fans were disappointed that Bucky wasn't returning to the role, the majority of readers are looking forward to Falcap. The problem that many have with it is not with Falcon himself, but rather that Rick Remender will be writing the main Cap ongoing, since his run has not been well-received at all, and is loaded with Unfortunate Implications.
Tanarus, the guy who's replaced Thor after Fear Itself is got hate immediately, because he looks like a Nineties Anti-Hero, his appearance and Thor's death mean that there won't be interaction between Thor and Kid!Loki for awhile, he's not using Mjolnir at all, but a weird staff with a heavy head (indicating to fans that he's not worthy to be Thor anyways, since a worthy person can lift the hammer), and for not being one of the many established people who could take over for Thor, namely Beta-Ray Bill and Thunderstrike. Oh, and the fact that when the announcement was made Thor wasn't even dead yet.
The first and last seem to be annoying people the most, since the first is clearly so Kid!Loki will have a harder time of it without Thor to protect him and the latter is seen as being too much like the DC reboot's treatment of well-liked characters.
In-universe, Loki loathes Taranus for this very reason. It's even worse for Loki because he's the one responsible for this situation.
Thankfully, this turned out to be wholly intentional on the writer's part, as Tanarus was revealed to be someone impersonation Thor who had usurped everyone but Loki's memories of him, and ended up integral to Thor's return. Notably, he really didn't star in most of the comics, Loki taking over that title too until Thor was back.
The new Ultimate Spider-Man, Miles Morales, was initially treated like this in-universe. A number of characters such as Nick Fury and Spider Woman felt it was disrespectful of Miles to don the Spider-Man mantle after the death of Peter Parker, but he managed to win both of them over after displaying his heroism during a battle with Electro. However he still routinely deals with cops and civilians who view his actions as disrespectful to Peter's memory.
Not like it didn't happen out of universe as well, however he's more of Base Breaker then purely hated. Some feel he's a very good character and the only good thing the Ultimate Universe has left and other think he's Peter Parker light with nothing really interesting about him. While the character has garnered fans since his introduction, the move is still debated - even after Ultimate Peter Parker's resurrection. and then the race thing comes up but let's not get into that
Kade Kilgore's Hellfire Club, main antagonists of Jason Aaron's Wolverine and the X-Men. In fairness to Aaron, the classic Hellfire Club members (and most of their direct replacements, too) are long dead or face-turned, but apparently he felt that the best characters to fill their shoes would be a cabal of sociopathic teenagers with a major Show, Don't Tell problem; they spend most of their panel-time talking about evil things that they did which we never see them do. They're typically referred to by derisive nicknames like "Heckfire Clubhouse" or "Hellfire Babies."
When Chris Claremont returned to the X-Men in the early 2000s, he created a number of new antagonists for them to fight, such as the Neo, the Shockwave Riders, Vargas, the disembodied telepath Elias Bogan, and a mutant slavery ring led by an alien named Tullamore Voge. None of these characters were particularly well-received, and most of them got a good deal of unnecessary Character Shilling comparing them favorably to the established villains - Apocalypse considered the Shockwave Riders Worthy Opponents, Bogan was said to be the ultimate head of the Hellfire Club despite never being mentioned before, and so on. It's probably telling that any time a writer other than Claremont has used one of these characters, they're shown being defeated in an amusingly undignified way, and ultimately most of them ended up as cannon fodder for Bat Family Crossovers.
This was the reaction when Mac Gargan (formerly the Scorpion) took over the identity of Venom from Eddie Brock. Not only was he the antithesis of everything Brock stood for (didn't bother protecting innocents, gave in to the symbiote's violent urges rather than controlling them, was completely selfish) but him getting the symbiote was just a blatant poor attempt to end the massive Villain Decay Gargan had gone through as Scorpion. However in the words of one reviewer; "a loser in a Venom suit is still a fucking loser". Nobody liked it and he ended up losing the symbiote after Dark Reign and Siege. Thankfully averted with Flash Thompson as Venom. Many consider him to be a great character in his own right and he's become a big fan-favorite.
Nova has Sam Alexander. Basically, Richard Rider had been the signature Nova Corpsman for nearly forty years, and he'd recently had an excellent run that concluded with a Heroic Sacrifice in The Thanos Imperative. The people who didn't want him back right away considered it a great conclusion to the franchise... so, of course, three years later, Jeph Loeb (one of Marvel's most widely-loathed writers) debuted a new Nova character. Sam Alexander won a lot of haters right away for his "arrogant hotheaded youth" personality, a far cry from the mature, experienced, and responsible Rider, and for his powers being completely inexplicable (the Nova Force died with Rider). He also got an immediate starring role in Ultimate Spider-Man, which is a Replacement Scrappyseries and only dug him deeper. Gerry Dugan rehabilitated Alexander to some degree, but than when Original Sin revealed what really happened to Rider, old wounds were reopened. Now people don't hate Sam, but most still direly want Rider back anyways. Exasperating the issue is that Sam is named after Loeb's late son, meaning he probably won't be going away.
The female Thor got this treatment from the very moment she was announced and it's only been getting worse with time:
Initially it wasn't anything against her character (her identity is a mystery at first and nothing about her was revealed), but due to the fact that she's using the Thor name. Unlike Captain America and Batman, that is Thor's legitimately real name. It's like if Dick Grayson just started calling himself Bruce Wayne out of nowhere. Marvel even said that she's not She-Thor or Thorgirl, but Thor. This also lead to confusion regarding solicitations and the like, which still refer to the real Thor as Thor, but also refer to female Thor as Thor.
Then there was the way the original Thor lost his hammer. Jason Aaron apparently thought that having Nick Fury whisper something mean into Thor's ear would be enough to have Thor lose his hammer. Having a beloved character be shoved out of his role through such an Ass Pull method angered some readers.
When her book actually started, things got even worse, as some saw it as having veryunsubtle and heavy-handed feminist messages and insulting subtext directed at anyone who disliked the change. Then came the Character Derailment of several characters (including Odin and fan favorite villains Absorbing Man and Titania) to further push those messages, which pissed off much of the fanbase. The series itself has in the view of some, become a Replacement Scrappy for the Cult ClassicJourney Into Mystery book which starred fan favorites Lady Sif and Beta Ray Bill.
A stranger case involves the identity of the new Thor, Jane Foster. The series blatantly teased taht she was actually Roz Solomon, and many people would have preferred they went that route, as many felt the revelation that she was Jane Foster was a twist for the sake of a twist and for diversity reasons. This subsided with the first issue of The Mighty Thor, which actually went in-depth in its portrayal of Jane Foster as a cancer patient.
Marvel fans are now accusing Marvel of turning The Inhumans into substitute X-Men. Originally a small, xenophobic cult of genetically modified humans who gained superpowers through exposure to mystic crystals, recent events have revealed that millions of people around the world have latent Inhuman DNA and are now gaining superpowers as a result of mass exposure to said crystals. Crystals which, incidentally sterilize mutants. Needless to say fans have been less than pleased with these developments, saying Marvel is clumsily attempting to replace the X-Men with the Inhumans as "Superpowered symbol of minorities" because Marvel owns the film rights to the Inhumans but not the X-Men.
With the real Wolverine dead, Marvel seems to really want to make Sabretooth into the new Wolverine. While X-23 is the one actually using the codename, Sabretooth is the one who is actually filling in the role Wolverine usually does; the token killer on a team who threatens violence on his enemies, but at the same time tries his hardest to ensure that no one else follows his path — including the bad guys — and is also The Atoner. However, fan reaction has been... polarised, at best. Many detractors point out that the guy is a bloodthirsty murderer and his high body count. Others point out that, unlike Logan and X-23, Victor didn't want to be redeemed. His morality was flipped literally by magic. And the fact that this change in direction to his character could only be achieved through such a contrived reason (even for comic book standards) means it's hard to take him seriously as a character.
Another part of this also stems from the fact that there already are heroic Sabretooths; they just tend to be alternate universe versions who don't have nearly as much blood on their hands. These versions are liked, and the mainstream Sabretooth is seen as a poor imitation of them.
When Marvel Comics bought out Malibu, they cancelled several titles and rebooted many others. Mantra was originally a title about a male warrior reincarnated in the body of female mystic and his struggle to cope with his new role. When Marvel took over, the central character was Put on a Bus by being banished to another dimension and the Mantra mantle was passed to minor background character; a teenaged girl who had appeared as a babysitter in a couple of issues. Needless to say, fans were not impressed. In fact, this seems to be the consensus reaction to everything Marvel did to the imprint.
When Acclaim bought Valiant Comics, they did this to every main character save Turok, who got more popular because now he was fighting cyborg dinosaurs. Then Acclaim went broke and the whole thing was tossed aside anyway, but by then it was a mercy killing.
Feral, the angstygoth in Strontium Dog. He wasn't a bad character in and of himself, but the fact that he replaced Johnny as the protagonist meant he was doomed from the start.
This can happen for whole teams as well. After the original Genął ended with the team being killed with a nuclear bomb, the book was relaunched with an all-new team created by Chris Claremont. The combination of the heavy-handed, editor-mandated deaths of the old team and the Five-Token Band nature of the replacements meant that the results were pretty unpopular. The "new" Genął was cancelled after 16 issues, ending with the original team being bought back to life. The "new" Gen 13 have never even been mentioned again.
