The Top 10 Franchises With the Worst Fandoms
Calling any fandom the “worst” is always a risky move, mostly because every community has average fans who just enjoy the thing and go home. That said, the internet has a way of amplifying the loudest voices, and some fandoms have built a reputation over the years for being a little more… intense than others.
With their endless arguments, review-bombing campaigns, and taking fictional debates a bit too personally, these groups tend to show up in the same conversations again and again. This article leans into that reputation, ranking them from mildly chaotic to full-on exhausting.
Five Nights at Freddy’s
The Five Nights at Freddy’s fandom mostly lives in a constant state of theory-building, which sounds harmless until you see how seriously some people take it. Lore debates can spiral into full-blown arguments over what is, at its core, a series about haunted animatronics. Add a younger fanbase into the mix, and you get a community that can be loud, obsessive, and occasionally hostile when someone “misinterprets” the timeline. Still, compared to others covered here, it’s more chaotic than outright toxic, with most of the drama staying contained within fan circles.
Steven Universe
A show built around empathy somehow ended up with a fandom known for the opposite at times. Online discussions around Steven Universe have included harassment toward artists and fans, especially over character portrayals or ‘ships.’ The irony hasn’t gone unnoticed, and it’s often brought up in broader fandom discourse. That said, much of the community is genuinely positive, which keeps it from ranking higher. When things go wrong, though, they tend to go very wrong, turning disagreements into personal attacks faster than expected.
Undertale
Undertale’s core message is about kindness, which makes its fandom reputation, not unlike Steven Universe’s, especially ironic. At its peak, players who didn’t follow the “right” path or accidentally spoiled parts of the game sometimes faced backlash. The community also became known for aggressively promoting the game across unrelated spaces. While things have calmed down over time, the reputation stuck. These days, it’s less intense, but the memory of how overwhelming the fandom could be still pops up in online discussions.
Doctor Who
Decades of history mean decades of opinions, and Doctor Who fans have plenty of them. Debates over regenerations, writing quality, and casting choices can get surprisingly heated, especially when the show shifts tone. Every new Doctor seems to restart the same arguments all over again. It’s not always hostile, but it is persistent, and the constant cycle of backlash and defense has become part of the fandom experience. At its best, it’s passionate. At its worst, it’s exhausting.
Marvel Cinematic Universe
The MCU fandom is massive, which means even a small percentage of negativity becomes very noticeable. Online, it’s often associated with tribal debates, review-bombing accusations, and defensive reactions to criticism. Discussions can quickly turn into arguments about box office numbers or “objective quality.” Most fans are just along for the ride, but the louder corners of the fandom have built a reputation for treating every movie like a battleground.
Rick and Morty
For a while, Rick and Morty fans were known for acting like the show required a high IQ to understand, which didn’t exactly help its reputation. The infamous Szechuan sauce incident only cemented that image. While things have mellowed out, the fandom is still often cited as an example of how not to behave in public over a TV show. The combination of smugness and chaos keeps it firmly in the middle of this list.
Genshin Impact
Genshin Impact’s global reach means its fandom is everywhere, and so is the drama. From coordinated review-bombing campaigns to constant debates over characters and rewards, the community has a reputation for reacting loudly and quickly. Social media doesn’t help, where minor issues can escalate into major controversies overnight. It’s not constant, but when it happens, it’s hard to ignore, giving the fandom a consistently chaotic presence online.
The Last of Us
The reaction to The Last of Us Part II pushed this fandom into the spotlight for all the wrong reasons. Backlash included review-bombing and harassment directed at developers and actors, which became widely reported. The debates themselves were intense, but it was the personal nature of some responses that stood out. It’s a clear example of how quickly strong emotional investment can turn into something far less constructive.
League of Legends
If there’s one fandom that consistently shows up in “most toxic” discussions, it’s League of Legends. The reputation comes less from social media drama and more from the game itself, where reports of verbal abuse, trolling, and rage-quitting have been common for years. Even developer efforts to curb behavior haven’t fully shaken that image. What makes it stand out is how normalized the negativity can feel, to the point where new players often hear warnings before even starting. It’s not that everyone is toxic, but the frequency and visibility of those interactions have made League the go-to example whenever this topic comes up.
Star Wars
Few fandoms are as iconic, or as divided, as Star Wars. Every trilogy, show, and casting choice seems to spark new waves of debate. Unfortunately, that has sometimes included harassment directed at actors and creators. The sheer size of the fanbase amplifies everything, turning disagreements into ongoing cultural conversations. At its best, it’s passionate and dedicated. At its worst, it’s the blueprint for nearly every “toxic fandom” discussion online.
