Yes, I do think that the city who heavily relies on their teenage superheroes because they are suffering under an emotional terrorist that doesn’t let them feel any sort of negative emotion lest they end up hurting the people that they love and whose literal only hope is, again, their teenage superheroes would end up being super fucking odd and super attached to said heroes.
And yes, I do think Paris would genuinely freak the hell out if they lost one of their superheroes. (They retired, they were permanently injured, they died, they moved to another city, etc.)
And yes, I do think they freak out badly.
And yes, I do think the fan culture there would be borderline cultish because they can’t (are not allowed to) feel negative emotions.
And yes, I do think Paris would riot if Gotham tried to steal one of their superheroes or if one of their superheroes left for Gotham. And if that superhero came back it would just be the ‘welcome home cheater’ meme.
Any city where the entire population (no matter who they are) could have their emotions used against them and be possessed by the weird magical abilities of some moth guy and be forced to hurt the people around you is just going to be a breeding ground for unhealthy personalities and attachment styles and habits and behaviours.
