Typically, a "well-written" character is one that develops in an unpredictable, yet realistic/understandable way (Sasuke), or has many 'layers' to their personality that are revealed to the reader throughout the story (Kabuto/Itachi/Danzo). However, some characters' personalities/values alone are enough to endear them to readers. For example, Rock Lee is a stagnant character with a one-dimensional personality, but the way he exhibits his personality is powerful enough to win readers over. Same thing with Naruto. Idk if I explained that too well...1. Madara/Hashirama
2. Naruto
3. n/a Probably Minato or Itachi
I don't really understand what "well-written" is suppose to mean, but i have chosen characters based on their values, contemplations (way of thinking), etc
