Mentors are the masters and advisors to the hero. They often train their pupils to save the world or otherwise protect the one they love. Most of these characters can be a part of the Lawful Good alignment as they teach their followers/pupils about a code of conduct—be it a personal one or a set of laws—and that an ideal world comes from promoting this dualism of structure and benevolence, and some can be a part of the Neutral Good alignment as they devote themselves to teach their followers about doing what's right is the most important thing in their lives or one of at least.

Best examples of this include Raiden from the Mortal Kombat series, Kakashi Hatake from the Naruto franchise, Albus Dumbledore from the Harry Potter series, and Yoda from the Star Wars franchise overall.
