"Team dad or mom" types who are barely older than the people they are dadding or momming. I don't mind say, Gibbs in NCIS cause he's a grown-ass actual adult and most of the team really is young enough to be his kids, but Shiro (or rather the fandom version of Shiro) from Voltron is what this smacks of to me. While it's a bit more rare in canon proper, it seems like fandom will run these types into the ground, with fanart and fanfiction really playing it up ad nauseum, and making it seem like they have no other traits than to watch over their teammates.

Gonna be honest: RP is primarily what soured me to this dynamic, where you have these people in the games who are maybe a teenager or at MOST in their mid-twenties out there being the "dad" or "mom" to a bunch of teen not even ten years younger than they are. And oftentimes these people are flanderized already from maybe caring about only a few people in canon into suddenly being a dad or mom to the whole frigging game. I've had to fight before to let my "adult" (by the standards of his time in the Middle Ages) character basically tell people to fuck off, that he is perfectly capable of taking care of himself even though he's sixteen and is gonna be offended if you try to adopt him, thank you very much. Never goes over well.
