I been thinking about this for a while. First with a the significant other of a hero without powers or a helping role, where we see their day to day life and how they feel insignificant next to the hero and all the action that take place away from them for the most. See different relations, ones where the hero over compensates for short-comings, one where they are toxic or even abuse panther in their. Mentors for heroes, who start the story with as mentors, mother/parents of heroes. Also when i mean full story, i don’t mean a single episode in a series or a poltline in a book, but a fully completed story centered around them alone.
some archs i thought of:
-the comedic relief -the powerhouse(usually written as dumb) -the villain(that is not just a serial killer) -the future seer/oracle
Feel free to add media/stories use the arch for the full stories
Henchmen.
The best example I can give is 21 and 24 in The Venture Bros. Just two grunts following their supervillain boss and surviving through their knowledge of tropes. It’s fun to look into the lives of the faceless goons of villains. See what they do in downtime, or what they talk about during an operation, or how they respond to their boss’s insane demands.
