Darkstalkers UDON comics version of Morrigan Aensland is this for fans of the character (which given her popularity, there are plenty). Unlike the games Morrigan is depicted as a despicable, disgusting and evil monster who only cares about draining human souls and shows a complete disregard for human life. Absolutely nothing in common with Morrigan in the games where she is friendly and moral for a succubus despite her thrill seeking personality.
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.
The Golliwog. The fact that you have a character whose design is a walking Blackface-Style Caricature is one thing, but the more notable part is that in a notorious Deconstructor Fleet, Moore decided to play the character (whose name is so associated with racism as to have inspired an actual slur) entirely straight as a benign fey creature who is nothing but helpful to the protagonists. Even those who thought there was something to the idea of reclaiming the character tend to feel this wasn't the way to go about it.
The Moonchild. The mere concept of the character as a vicious Take That! to Harry Potter immediately drives off a lot of people. Meanwhile, those on board with the idea tend to find him to be a pretty weak take on it, as Moore ignores all the things one could criticize about the character: while Jimmy Bond was rooted in real critique of Fleming's Bond and had enough intrigue to be Love to Hate, the Moonchild has essentially nothing in common with Harry Potter, and moreover, isn't given any interesting or redeeming qualities or even much personality at all besides being an unflattering caricature of the younger generation. While the banal nature of his character and actions is intentional to a degree, it doesn't change the fact that he's still a major player in the last part of Century and ends up killing one of the main characters, which forces the reader to take him at face value as a villain when the entire narrative is screaming at them that he sucks and shouldn't exist.
Les Légendaires: El Diablo; the character is a ridiculous and obnoxious villain with an ego so big he was actually willing to risk a possible cure to Alysia's condition (including his) just to keep his reputation as a great thief. Despite being a rather pathetic villain, he made the Legendaries look ridiculous when stealing them the cure, and they never had an occasion for a payback. Fortunately, he only showed up once.
The IDW comics original character Drift took a lot of flak from the fans in his early days, considering that he was built on everything his creator happens to like about Japan. What makes it particularly egregious is that his creator claims he was made to fill in a role that no previous character could, when Transformers is known for having a massive cast, and Drift is basically just a young Star Saber with Getaway's vehicle mode. In The Transformers: More than Meets the Eye: Drift has been rescued, as the author plays up his spiritual side, and makes him the fundamentalist, as well as a Deadpan Snarker.
Humans in general in Transformers stories tend to have an uphill battle, but Spike Witwicky goes above and beyond in terms of being unanimously disliked. While his cartoon counterpart was a classic Token Human civilian teenager, inoffensive if a bit dull, Transformers: All Hail Megatron reinvented him as a soldier, aiming to make him more of a tough badass who could hang with the Autobots. Unfortunately, they overshot "tough badass" and landed instead on "asshole"—Spike's actions in the ongoing included constantly griping, neglecting his duties for one-night stands, and expressing rude opinions about the Autobots and Cybertronians in general. The thing that really pushed him off the rails, though, was an issue meant to serve as his big spotlight—an issue in which he abandons his post to track down, trap, and execute a Decepticon over a personal vendetta, all while ranting to himself about how Muggles Do It Better. The fact that writer Mike Costa had gone on record acknowledging his own dissatisfaction with writing Transformers really didn't help the accusations of him being an Author Avatar. The fallout from the issue was so severe that the only way the writers could think of to rescue him was to make him Evil All Along towards the ongoing's end, declaring that he'd only kept his job due to his dad being a general, with John Barber in particular reworking him as a full-on Hate SinkSmug Snake (in the process, changing very little about him).
From The Walking Dead, 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).
