Here’s another character archetype for you: the friend that becomes an enemy (or the enemy who becomes a friend). This one is pretty straightforward. At some point, someone the hero thought they knew betrays them. OR, at some point, someone the hero thought they knew actually helps the hero out.
Rather than give you a long-winded whatever about this one, I thought I’d just ask you.
Who are your favorite frenemies from literature (interpret “literature” however you’d like)?
