I tried to think abt this cuz I have a ton of different medias with characters I've straight up latched on to...

Idk if this counts but it's generally characters with issues regarding their ego/sense of self, trust issues, can't handle their envy/jealousy, anger issues or are commonly submerged in their own fantasy. Idk if that's weird or anything but I can't help it, that's what has brought me comfort.
