It varies though. But I'd say generally the cast doesn't fit this archetype very well anyway.
You sure Fang is a big guy? I mean she is last person to join the group, she wasn't there when everyone received their marks, the person who she is trying to protect to protect is within, their group(unlike Dajh and Serah), and she turns into Ragnarok(kind of). This is ample enough evidence to prove she is a sixth ranger.
