AN: Yes this is more Sephiroth, I am working on the next chapter of Summer Vacation, but I just had a breakthrough wit this story in terms to ideas. This one is mainly setting things up for what is still to come, and it should keep things going.

X-over- Yeah, that's part of what this is, even the initieative underestimates him, the Order of Teraka does the same, he's of a higher order than everything else on the planet which is the major problem, and the order was contracted by either Wolfram and Hart or Mayor Wilkens, I'm not totally sure yet.

The white haired warrior ran, evading bullets with a ballet like grace, the occasional shower of sparks glinted through the shadows when bullet met blade. He rolled over the railing of the stairs and landed on the trooper who was shooting at him, an easy kill with a strike of the blade.

Xander groaned as a glance out the window spotted five more SWAT vans than had been there when last he had checked. A mental count of those trying to deal with him had a smile cross his lips, they didn't have near enough of a force if he let Sephiroth come out and play, but he was consciously suppressing that half of himself in favor of his more human and definitely sane half. So far outside there were twenty seven SWT units, the local cops, three retrieval/elimination teams of cleaners the watchers sent, a few dozen assassins from the Order of Teraka, the national guard, and a group of military yahoo's that carried some sort of electric rifle and referred to him as a hostile sub whatever. It was definitely not the kind of enemy he had expected to run into in Ohio in the first place.

It made for an interesting situation in the middle of Dayton, but hey, interesting meant a rather normal day, or at least a boring one.

He snatched the fire extinguisher off the wall and forced the hose into the next assassin's mouth and turned it on, watching the man sink to the floor.

With a quick motion, he was through the door and running down a hallway, blade flashing as he charged the group of soldier boys with giant tazers. Blood filled the air, but none touched him as he moved away before his foes even realized they had been sliced open. He spun the blade in a slow figure eight, the blade still clean as he did so, it had moved at speeds so fast that it hadn't even touched the skin; its very passing had caused the damage.

From within a horribly deranged laugh began to fill him, the demon within him was pleased; it asked 'mother' if she was pleased with him. Xander felt sick at the notion, he felt the creature grow stronger as he fought, harder to control, harder to keep down from merging completely with him.

For a moment he paused, surrounded by the corpses of the soldiers, their marking claiming them as members of some unit called the Initiative. His mind battling against the bloodlust that was consuming him whole.

He forced his breath to slow down from the rapid fire panting it had to a slower, calmer pattern as his stomach threatened to spread its contents across the floor. His eyes flashed for the barest instant, revealing Sephiroth's Mako energy infused ones before his calming technique gave him back his edge and they vanished once more.

One of the watcher goons fired through the thin walls with an assault rifle, but Xander didn't show one ounce of care as he drove his fist through the wall and dragged the man through to send him flying through an office's open door and out a window the land atop a SWAT van.

Sephiroth rushed to the surface, shattering the barriers and achieving dominance, Xander's thoughts went to what had driven him from Sunnydale.

"Xander, please tell us what happened, what changed you into this?" Buffy asked, she and Willow both seemed to be halfway into shock, but they still held on to their control.

"How, how could you do that to those people?" Willow asked, tears finally coming.

He fought against the arrogance he had gained from his other half, and hated himself for what he had done, but to that part of him, it was a necessary evil. An evil, yes, but one that had to be committed. His soul was at war with itself, a battle that would not be won or lost then.

The white haired one slowly sat down, eyes closed, the calm façade he wore during his strike against Wolfram and Hart just beginning to crack.

"I did what had to be done; they had to learn that it is not okay to go around summoning demons into the world for fun," he managed to say after a long moment of thought, "And I changed because those bastards in power up there decided that my Halloween costumes character was far to powerful and were trying to stop Sephiroth then, but the spell was ended while they were messing with it, I got stuck with that psychopaths memories and abilities, he's become a part of me."

"Who did?" Buffy stammered, confused, not recognizing the name, but her mind flashed to the destruction Xander had confessed to the next morning.

"I dressed up as Sephiroth, a lethal warrior who makes most of our enemies seem like cute little puppies on tranquilizers," the formerly dark haired man said slowly, "And I still have part of him up there in my head, the one plus side was that it helped me deal with Spike and Drusilla, but I have the darker parts as well."

"What?" Buffy managed to say, "I knew we hadn't seen anything out of Spike for a while, but how the hell did you deal with them?"

"Quite simple, I turned them into frogs," Xander chuckled, in fact they are in a terrarium in my room at the moment."

But an instant later the familiar, joking face of their friend was replaced once more with the hardened face of the warrior he held within him. It was a disturbing sight to behold, especially for Willow who had known him her entire life, it just broke something within her to see him this way.

The looks forced Xander to make a decision, he couldn't stay in the city, he had changed far too much to remain, and it just felt wrong somehow. The feeling hurt, but he knew in both parts of him that it was the best choice, he couldn't afford to put his friends through this sort of thing, especially if Sephiroth came to the surface and tried to hurt them.

Xander returned to control as he reached the roof via the elevator, one Terakan pinned to the wall by chair legs now implanted through the shoulders, elbows, and knees. The mage was still alive, but only just though his voice was removed by a silencing spell. The only sound coming from him was the gurgling of blood.

The warrior stepped forwards into what his foes believed was a trap that they had set for him, but they weren't prepared for what he did, a simple casting of Ultima leveled the roof with the same potency as an atomic device. But that wasn't all, the white haired entity leaped clear of the burst of light, snatching the strut of the police chopper that had circled around to provide support.

It was at that very moment that the failsafe bomb the Initiative squads had left behind incase they were all taken down went off in the basement of the building, consuming it in pillar of flames and rubble.

Masamune lashed out, removing the tail of the aircraft as the one winged angel landed atop the next building and was running as the attention of those around him had diverted to the chaos behind him, death and destruction raining down around him as he pulled a vanishing act.

As Xander made his escape from the hands of the combined forces of several groups out for his head, across the continent, his friends where having a meeting of their own.

It was a solemn occasion, a month had passed since Xander had vanished, leaving letters to be delivered to them the next day saying that he couldn't put them through what was happening to him.

They smiled slightly at memories as they glanced at the picture on the mantle, one taken that night by Joyce Summers, the night when everything changed. The night before Xander's smile became something far less common than it would have required to be placed upon the endangered species list. It was also the night where their friend had the consciousness of a psychopathic killer imprinted within his head.

Giles clearing his thoughts at what he had to say, it wasn't good news, but it was news.

"I have something to confess," he said as they all just sat their, seeming to stare into space, "I made a miscalculation as to how I asked the Council to help."

"What happened?" Willow stammered.

"They decided that he was a threat to be dealt with, and he's already eliminated seven teams in various cities in the country, that's all I got out of it."

"How...how could you..." Buffy said, both girls crying at the thought of an accident leading to their friend being hunted.

Back with Xander, he smiled as he stepped up to the window at the airline t Dayton International.

"Yes, a ticket for Alexander Sephiroth for London," he said as the lady asked him about it.

Moments later, the white haired being was on his way to jolly old England to settle the score with a group of tweed wearing pests who would soon feel his wrath.

The watchers were going to pay.
