Today, we have Auron. I. LOVE. AURON. He's one of the best characters from ANY series I've played and I have a total thing for him. Why?
Because Auron is the shit.
Oh. You need better reasons? Well fine.
Auron is one of those men who is blunt when he has to be and silent when he should be. He's somewhat of a father-ish figure to the protagonist Tidus, and he's by far one of the most useful characters you'll have. I can't remember a major battle where I didn't have Auron on the front line. He's a heavy-hitter, dependable, and can kick serious butt.
