Link from the Legend of Zelda. He goes out of his way to help people, not because he thinks he can get something out of it, but because it's the right thing to do. He's always willing to risk himself for his friends, and has a strong sense of duty. He can be playful or heroic if the occasion calls for it and he's an all round good person. Sure he doesn't say much, but he's a great listener. He's nice, but not a goody two-shoes. He's willing to circumvent the rules if the reason's good enough.
He's athletic, but not jock-like or thuggish, he's artistic and musical, but not spacey. We know because he can solve feindish puzzles all the time that he's an intelligent guy. Whenever we see him not as a child, he's a responsible and productive member of society who holds down a steady job (Dude even drives a train at one point. How awesome is that?) He seems like he'd be a pretty cool guy to get to know.
So yeah, Link's awesome, and anyone who says he's boring and flat as a hero because he doesn't talk is clearly not paying attention.
