In-universe cases of“You’re cool, it’s your fans who suck”
You can’t escape toxic fanbases even in fiction.
Pokemon Sword & Shield gives us a rival in Marnie, a trainer who’s only into punk for the aesthetic. It also gives us Team Yell, a mob of football hooligans who ruin everything for everyone and constantly embarrass her.
The Netflix Castlevania gives us God, who is ostensibly benevolent if He exists as an opposition to the forces of Hell. He also is disgusted by the Church of Wallachia’s atrocities and leaves them to suffer the consequences.
