Anyway, i wish i hadn't quoted that because now, my long, initial post that i put so much effort into will go completely un-debated :/
>:D
*snippets regarding the story for SCV*
Raphael: Was a vampire due to stabbing Soul Edge in the eye and wounds the original Nightmare gave him(Soul Edge bled into his wounds?), now he's dead. Or a zombie. I'm not certain the people who wrote the story know themselves >.> It's been said quite a few times, his story would appear to pick up after Zwei 'kills' Nightmare. Raphael wakes up in some kinky dungeon Schwarzwind occupies and begins reenacting a Twilight fanfic fighting with the apparently not-dead Zwei over Viola/Amy, who herself is confused as fuck as to what's going on and why after being in her thirties she still has the figure of a loli.
Taki: She ends up giving Natsu Mekkimaru at some point, if the unlock method for the weapon in SCV and Natsu being overwhelmingly described as her successor are any good indicators. Takis role in the story is pretty much done after relinquishing Mekkimaru to Natsu, whom somehow proved herself worthy of wielding it. Or maybe Taki was intended to die and Natsu is forced to carry the burden of harboring both a demon within her and a Soul Edge-tainted sword that is powerful enough to drive Takis own master insane. Anyone capable of doing that is a worthy successor in my book.
Kilik: Xiba is more mysterious than he is. And like you said, much of his relationship with Xiba can be copypasta'd from the Taki/Natsu relationship, except how he's the son of Kilik and Xianghua. I'd imagine that would have some importance, but Kilik doesn't seem to give a damn about his own son as much some little girl who looks like a chick he boned. It's perplexing x.x
Hilde: It seems to me that she has strong, negative ties to Dumas/Nightmare and Dampierre. I was under the impression Dumas basically razed Wolfkrone with the help of weapons given to him by Dampierre(notably the elephants seen in Hildes stage which IIRC are mentioned in Dampierres profile), and she's outright bloodthirsty towards Nightmare this time around(if only she had some in-battle quotes specific to him), while she doesn't seem to be aware of Dampierres role in the fall of her kingdom. Traveling with Schwarzwind now though, she could add additional conflict to the Twilight fanfic with Raphael/ViolAmy/Zwei and spice it up as an additional voice citing 'kill that mofo' as the best course of action. Maybe Siegfried preaches of redemption to calm her down? Haha.
Ivy: Yeah, her place in the story seems pretty shaky. She really doesn't do anything that Kilik, Edge Master, or Zasalamel couldn't. Probably :/
Cervantes: He's an anomaly. "Of this world once more but no longer bound by its rules," I dunno. Would he know how to go back to ye olde Astral Chaos without using magic soul-eating swords now? I'd only hope he has some role in the battle with Algol everything seems to lead towards in SCVs story, maybe as some sort of unwilling aid to the heroic characters. A token evil dude fighting with the heroes might be fun.
Aeon: I was under the impression his story implied he would be highly interested in eating Patroklos and Pyrrha as an attempt to regain more of his...sanity? Self? Well, whatever it is. I don't think he has need or the ability to have a croney acting in his stead at this point, I could imagine him just roaming around looking for more tasty "holy warriors" to eat up.
Mitsurugi: Yeah, he's boring. I can imagine how he would have some pivotal role in stopping Algols generic "I r teh loerd f al tiem an spays" routine, but wow is he uninteresting. GO BACK TO YOUR FARM WHERE YOU BELONG!
Maxi: You forgot the whole mentorship dealie with Leixia, Natsu, and Xiba. Xianghua is too busy being some generals concubine, Natsu is an orphan, and Kilik is just simply a deadbeat dad. So who else is going to be a parental figure to these poor souls? Plus, the army of Astaroths. He still wants vengeance after killing Astaroth twice and he himself died, but being a fighting game where death is cheap...More Astaroths to kill! The pirate thing is moot at this point, I think. He doesn't act a it like a pirate, he may as well either lose that bit of info from his profile or strike up a new rivalry with Cervantes. "Piracy is bad, m'kay. You shouldn't pirate."
Dampierre: He sold Pyrrha into slavery, dealt with Dumas/Nightmare/Raphael to help destroy Wolfkrone, and likely has had some scheming with Tira at some point giving how they both have been exploiting Pyrrha. If anything, he rivals Cervantes as the most evil mofo in the series right now. The difference being that he's less overt about his evil, more clever and deceptive about it. I am left bewildered by his opening line against Nightmare though, especially since he seems to have no hint of fear or even surprise when coming face-to-face with a soul-eating demon that has been the bane of Eurasia for so long :O I don't think he's just putting on a poker face or unaware of who/what he's up against, I think he is sincerely unafraid and unimpressed. And that's kind of scary.
Voldo: Yeah, Dumas/Nightmare servant that wants nothing less than to actually have sex with Soul Edge now. What else could he do other than try and ensure Pyrrha isn't cured of her evilness and maybe help Algol get out of astral chaos? I see no other way for him to achieve his desire.
Algol: Nah, he's the center of the story really. Everything points towards him orchestrating some kooky plot to stop being imaginary and rule the world. Edge Master seems like the only character who's aware of it, I wouldn't put it past Zasalamel or Dampierre knowing either though. It looks to me more like he was responsible for ye olde soul-devouring swords reawakening and he has some agents lurking about trying to help make him real again. Does Dampierre see a potential fortune in serving or possibly overthrowing a god-king? Was Tira promised assimilation in exchange for helping to resurrect Soul Edge? Could this Arahabaki be him possessing Natsu? Is he pulling the strings of Fygul Cestemus? Was he how Cervantes lived after Ivy apparently killed him?
Edge Master: The only one we know is aware of Algols plot and only one actively working to stop him, unless Talim and/or Zasalamel are also acting against him. I think he'd be pretty important in gathering the good guys to stop Algol, really.
tl;dr version: Although still crap by default for being a fighting game story, the story of SC is wildly complex and...stuff.
