I think not. Tifa was a girl girl (not even 500 lb men have that kind of frontal anatomy), and wasn't all that intimidating. I'd love to see a female Sephiroth type of strong (minus the darkness and evil). Like a gorgeous elegant (Tifa is NOT elegant) lady in her mid twenties that is an extremely good sword fighter, or something like it. (Hehe, I've written a novel already, and that's one of the main characters.)
Zidane, gotta love him. I want to see another Zidane, or at least a regular ordinary kid that embarks on a quest or adventure. And also one that DOESN'T get super powers, but uses his will instead to survive.
