Lately, the Deku x Bakugo pairing gets more direct pushback than it used to. I don't even hate the ship conceptually, but the sheer volume of content where Bakugo's early bullying is reframed as some tortured love language makes me close the tab. It's not the enemies-to-lovers dynamic itself; it's how often the narrative minimizes the actual harm. The extreme power gap doesn't help either—feels more like fantasy than a natural extension of the characters.
On the other end, Endeavor x Hawks comes up as deeply uncomfortable for obvious reasons. That's not a ship with potential; it's just ignoring the show's entire point about abuse of power and trauma. I've seen it pop up, and the comments are usually a hard 'no' with some genuine bafflement about who'd write that.
Oh, and I've noticed a quieter but consistent distaste for older character/student ships like Aizawa x Midoriya or All Might x Midoriya. People tag them with warnings, sure, but the vibe in general discussion threads is major side-eye. The student status and mentor dynamic makes the age gap creepy in a way that fantasy AUs can't really fix.
Sometimes I wonder if the worst ships are just the ones that feel the least earned, you know? They either twist a core character trait past recognition or ignore the established world's moral lines entirely.
