Not sure if this has been brought up before, but I'm pretty sure that la mariposa from doa4 is lisa from doaxbv. After I beat single player with her and saw the cutscene where she is unmasked, I saw how similar they looked. I checked out lisa's bio and her height and weight is exactly the same. One like's apple pie though, the other likes cherry pie, maybe her pie preference changed over the years?
Sorry if this is old, but I just got my xbox this week!
