Tifa is the classic choice and is almost as iconic in the realm of nerd fantasy as Lara Croft. In Final Fantasy VII, she is the tough but sensitive, fist fighting, cat fighting, monk of the group. Notably, she covers her booty in a tight pair of leather hot pants. It is almost as if the designers had “sex symbol” in mind when they made her because her victory dance depicts her stretching her arms behind her back to prominently display her ridiculous assets.
In Final Fantasy VII: Advent Children, she trades in the white top for a leather one, so she knows leather makes things better.
