Haha. Nope. Those questions are best left unanswered.
I'm all ears for a Waffle theory.
As you see, there are actually 2 Marias in that picture, in the Earth-1 crisis, she is a magical girl who wears a skirt, which are in correlation in Rondo, she grows up to be the Maria in the Playstation and PSP SoTN, where she never fully tapped into her power.
Earth-2 Maria spawns from a slight pitch, causing her to be more tomboyish and wearing the superior bike-shorts, following the events of D-XX, she grows up to be Saturn SOTN maria, not being strong enough to fight dracula the first time, she becomes the only
other JoJo character in Castlevania.
Earth 2 comes from St. Germain's time-fuckery in CoD, which involved him trying to find the source of these new events, which would be the "Chaos Maker" or "That Man", Once he figured out Dracula's source of power, he immediately devised a plan to destroy him, only problem is only a Belmont can do the job and due to recent constant resurrections making holes in the timeline, and wearing down the bloodline's charge to the Vampire Killer, St. Germain Teamed up with Alucard who just killed Ritcher in his timeline, devised a plan to seperate Belmont's from the whip long enough to fight a full powered dracula, which involves Maria, since she's so powerful in Earth-2, she can help.
