Male = A sort of carefree, wandering spirit, who loves to gorge on food, but when the going gets on, he's down to earth serious. Naive, would be a good word to use here.
Female = A battle-hardened veteran of war who has her share of scars. Portrayed as cold and distant, she is headstrong and independent, not relying on anyone.
So any teenage boy that you put in armor and give a sword, and any female character that acts like Lightning (FFXIII).
I'll be honest, I thought Lightning was awesome, but a little *too* distant. I felt that by the time they actually explained her story, it kinda bored me because of how much they dragged it out. So I guess the only thing I can say on this is be careful when developing a character like this. Don't wanna bore the crowd with something extremely cliche either.

My own response:
Male - a lot like Dart (Legend of Dragoon), Cecil (FFIV DS) or the lead Protagonist of Shining Force. They're friendly and quick to help, and are obviously strong. Their lives are linked to a mystical weapon. The white mage always seems to have a thing for them. Optimistic.
* this is all if we're all talking about just human types. Otherwise, I claim the smart alleck Dwarf from Sacred Gold.
Female - If she is the lead, then i'd say something like... Lara Croft (Tomb Raider, duh.) Smart, wealthy, sexy, and adventurous.
