The Scrappy / Baldur's Gate

• Khalid is more or less The Unfavorite in the eyes of the fandom, due to being a weak-willed Generic Guy whose stats were outclassed by other fighters - Kagain was the better tank, while Shar-Teel, Montaron, Ajantis and Coran were better on the damage front, Rasaad's speed makes up for how little equipment he can use, and Dorn is the perfect pack mule. He also had the bad habit of running away because he was very prone to morale failures. Worse yet, he was attached at the hip to Jaheira and the player couldn't get rid of him without losing her as well. That said, his death hit many players hard, no doubt in part because of the effect it had on Jaheira. And players that disliked him still called foul for his sake when the novelization radically changed his personality for the worse.
• Quayle was probably the closest runner-up for the "honour" in the first game. All his stats were awful except his Intelligence and his every quote made him sound like a Boisterous Weakling and Insufferable Genius. Players warmed up to him in the second game because of his unselfish tender loving-care for Aerie and an admission by the man himself that he wasn't as nice then as he is now.
• Several NPCs have minor hatedoms. Anomen, however, has a fairly major one, not only because he's a major jerkass and a hypocrite but, until the Enhanced Edition came out, for being the only canonical female Player Character love interest on top of that. It really doesn't help that initially, he really has pretty average Wisdom scores - something Clerics needed plenty of in order to cast quite a few high-level spells. His personal quest is reasonably well-regarded, Schrödinger's Gun issues aside, for providing worthy character development in terms of both revealing why he is the way he is and either causing him to grow up and becomes a better, mellower, and nicer person or sink into bitterness and despair, but while most party members' personal quests are activated on a timer Anomen has to gain TWO LEVELS to trigger it, which means you have to endure his assholeness for quite a long time. And if you help him succeed his trial, his wisdom score goes from 12 to 16... which he will lose to bugs in Throne of Bhaal, if he wasn't in the party at the end of Shadows of Amn.
• There's also the non-playable-non-player character Queen Ellesime, whose actions in the backstory and perceived belief in Can't Argue with Elves (she's one) have earned some hate. Her past actions aren't really shown in a good light, in effect having created someone who's seen as a monster by everyone in-game, but the dislike seems to be aimed towards a more flanderized version of the character; she did admit her mistake at the end, and presumably there were reasons for it other than just one-dimensional arrogance. To expand upon it, Ellesime dated the Big Bad, then dumped him after he committed his first real act of ultimate-taboo-evil, and decided that stripping him and his sister of their souls and exiling them to live outside of the Hidden Elf Village until they died as mortals was a good punishment. While leaving him with all his incredible magical powers, of course. In her own words, she hoped that their change in circumstances which teach them to appreciate how good the elves have it, and learn some humility. Shockingly, it didn't quite work out like that. So, while her actual demeanor is somewhat apologetic about the whole thing, some people find this insufficient recompense considering how epically she screwed up. This leads to the above mentioned Flanderization.
• Elminster. Many people feel that he is too powerful in his role in the first game (he is Nigh-Invulnerable) and your Journal entry will glorify him regardless of your attitude. It also doesn't help that his role in the series essentially boils down to giving you tidbits of information that you just risked life and limb to scratch from the remotest corners of the Sword Coast, while barely making any efforts to lift a finger himself. Baldur's Gate III didn't do much to endear him to players as his only role in the story is to tell his protégé the beloved Squishy Wizard Gale to perform a Stupid Sacrifice on the behalf of their goddess who abandoned him.
• Abdel Adrian, the protagonist from the novels, is a big reason why they are considered Fanon Discontinuity. Considering that the game provide a wealth of options for character creation, he's already got a strike against him by being the most generic protagonist possible - a Dumb Muscle male human fighter. But what truly pushes him into this is his Jerkass personality; He treats his companions with contempt, cheats on his romantic partner, fights like a thug, and is more interested in money and base pleasures than anything else. The novels treat him as a skilled and seductive Anti-Hero, but the fanbase doesn't buy it one bit and he's widely seen as an unlikable Designated Hero. It doesn't help the novel also completely warped the personalities of several characters like Khalid as seen above so Abdel can shine. Baldur's Gate III deliberately unpersoned him as a result of this with even characters who knew him personally refusing to use his name or pronouns, and the only indication Abdel ever existed being a hidden NPC who gifts you his shield.
