An interesting thing I’ve noticed with how Fire Emblem designs their classes: there is always a character, typically the first of that class, who becomes the pattern on which every other character of that class type is modeled on. It’s more obvious when FE introduced multi-classing as a thing for the Shadow Dragon remake, Awakening, and Fates, but you can still find exemplars in the older games.
I’ll probably put it in a different post who those Exemplars are, but a few off the top of my head in Shadows of Valentia: Mycen is the Exemplar Gold Knight. that one purple haired villain dude is the exemplar Paladin, Clive is the exemplar cavalier, Lukas is the exemplar soldier, and etc.
It also makes it obvious when characters then break design type: ex Tharja in Awakening is the exemplar Dark Mage, and it shows with how the enemy Dark Mages are designed, but then they break type very deliberately with Henry, whois far more covered up than Tharja or any other male Dark Mage.
