What is a "Big Brother Mentor"?

This character is the hero's good friend. The hero can hang around with him, go to the a resturant with him for a drink and talk about some good old man-business with him. Additionally, the character, being older and wiser than the hero, also acts as a mentor to the hero in times of need or advice.

However, just because the Big Brother Mentor cares about the hero doesn't mean that he can't suddenly break out of his buddy personality if he thinks he goes toon far. He only wants the best out of the hero, but won't hesitate to educate him the hard way if the hero shows reluctance to learn or has a tendency to run headlong into danger. In essence, he's the ideal big brother figure who knows when to get friendly or strict.

He can also be caring and even act as a form of comfort.

I like this article.
Being a hero can be difficult and they may need someone to talk to or vent.

I like DD as this character it suits him nicely.
