Isabelle is a fan favorite in the Animal Crossing series, but just like players have their own villagers they dislike, it's likely that she has some she loathes as well. The lovable dog villager wears a ton of different hats over the course of the games, from the mayor's assistant to the secretary, and that makes her a vital part of every community she's in. She's quirky and hardworking and never lets the player down or fails to remind them of important upcoming events, a villager's birthday, or a special event, like the Animal Crossing International Museum Day Stamp Rally.
Isabelle is a genuinely polite character. She is always there to help the player when needed and will guide them through their requests and changes to the island. She is overall well respected in the community and the villagers will follow her lead when it comes to almost every aspect of their daily lives. Isabelle has a great amount of power and can tell villagers to change their clothes or stop using a specific catchphrase. No character has ever shown true disdain for Isabelle, but it is likely that some of them would not be as excited about her laying down the law as others are. Alternatively, one would think that Isabelle would get along with all of the villagers, because of her easy-going personality, but there are definitely a few she would not be a fan of. Some of the villagers Isabelle would probably hate are amongst some that are considered Animal Crossing's best new villagers, while others are on the list of players' most universally hated.
There is likely one specific personality type that Isabelle would despise, and another that she would generally find unappealing. These are the cranky and lazy personality types. There are some villagers in this category that Isabelle probably wouldn't mind, like Gonzo (who usually just keeps to himself and enjoys nature), or Stitches (who is peppy and playful in his own right). While Isabelle can tolerate the unique personalities of Animal Crossing's villagers quite well, it would not be surprising at all if there were a few that she just could not stand.
Animal Crossing Villager Marlo The Mafioso Is Up To Something
Understandably, Marlo fans aren't going to be too happy about this, but there's a good chance that Isabelle would hate him. Marlo has the cranky personality type, which immediately puts him at odds with Isabelle. To make matters worse, it is rumored that Marlo runs an underground community, likely something related to a mafia-type crime ring. Though Marlo's true involvement with the mob isn't the biggest mystery in the Animal Crossing world, Isabelle would see that as a threat to her community and definitely be wary of him.
Isabelle might feel slightly threatened by Marlo's presence on the island, though it would never be shown to anyone. She would keep a close eye on him and make sure that he isn't up to no good and probably wouldn't mind telling him to change his signature "gabeesh" catchphrase if the player requested it. With education as his hobby, Marlo might be able to win Isabelle over but it would probably take a lot of time for her to gain that trust in him.
Monique Is Too Dramatic For Isabelle In Animal Crossing
Isabelle usually gets along quite well with the snooty personality types in Animal Crossing. The overall feeling is that, though many of them are concerned with their make-up, clothes, and gossip, they would like Isabelle mainly because of her take-control personality and Isabelle would admire them for their aspirations in life. With many of the snooty personality types having goals of being a politician, lawyer, or judge, they may enjoy Isabelle's experience pushing rules and getting down to business. Monique, on the other hand, would not enjoy Isabelle's personality, nor would Isabelle like Monique's. Monique cares about her looks so much that Isabelle would likely find this frustrating since it interferes with getting things done. Monique would probably try to boss Isabelle around and would not shy away from letting her know if she was doing something wrong.
Isabelle doesn't come across as a materialistic character at all, but Monique definitely does. With her high standards, she often acts as though the rest of the community is below her. Monique has been known to cause drama with other Animal Crossing villagers, especially the lazy ones, and Isabelle would never stand for that.
ACNH Villagers - Cyd Is Way Too Punk Rock for Isabelle's Taste
Cyd is definitely the wild one in the Animal Crossing series. He has the "Rockin" aesthetic and likes to play his music as loud as possible, which would rub Isabelle the wrong way. Cyd gives off a punk vibe and would definitely be uninterested in listening to Isabelle's rules. Isabelle would dislike everything that Cyd stands for, which is being loud and going against the grain. Isabelle knows how to have fun, though she is usually always working, but also knows when it's time to get to work.
Cyd is interested in showing off his music skills and also, thanks to the room design ability in Animal Crossing: Happy Home Paradise DLC, players learned that Cyd is interested in showing off his gaming skills. Isabelle doesn't seem like the type to enjoy video games at all so this would also be something that would make her hate him. Isabelle might not necessarily hate Cyd, but she would probably find his personality and irresponsibility frustrating enough to dislike him and would likely try to not associate with him unless she absolutely had to.
Animal Crossing's Isabelle Would Probably Hate Barold Too
This one is quite simple: Barold is just a creepy villager. Everything about the bear just seems unappealing and many fans agree. With his offputting personality, the fact that he has security cameras and a sleeping bag in his home, and his overall looks, Barold is easily the creepiest villager that has ever existed. The disdain for this character even has fans hoping for his removal as a villager in the next Animal Crossing game. That being said, Isabelle would definitely hate him. He would make Isabelle feel uncomfortable with just the interior of his home, but the rest of his appearance and personality would add to her discomfort. There are many other lazy characters that Isabelle would get along with, but Barold is not one of them.
Isabelle would try to give him the benefit of the doubt, but if he is as creepy as he appears, she would want to protect the rest of the villagers from whatever nefarious plan he has in store with his security camera living room. Barold will most likely go down in history as the most hated Animal Crossing villager, and Isabelle would definitely agree.
