Aragorn, INFJ
Consider Aragorn from Lord of the Rings, an INFJ personality type. His dominant, introverted intuition gives him a clear vision of the future and his role in it, while his auxiliary function, extraverted feeling, allows him to understand and lead others effectively. Essentially, he starts out as a ranger class of sorts, but as his journey progresses, he embraces his ability to organize and rally people as a king class too, an envoy, the ability to unify and bring people together.
This evolution of his cognitive functions allows him to face increasingly complex challenges, from wilderness survival to leading armies and ruling kingdoms.
