AN: This is the final part of the actual storyline, there will be one more chapter after this, but that is more of a tying everything together for the next part. I've already decided on the name of the second storyline, 'Summer Vacation'. And there is a lot to do with it, besides, it will eventually give Sonic the D-Board.

Kat Hawkins- There may be, not quite sure as of yet, there won't be at least until after the next storyline though

Super Sonic and Cyber Sonic collided midair, blades striking out, utter control meeting unrestrained fury. The crater was shaking like a high level quake, forcing the Scoobies back if they wanted to remain out of the high speed fight occurring below.

The glowing hedgehog parried a strike and retaliated with a blast of raw chaos energy that hurled the cyborg backwards, leaving a crater where it smashed into the solid rock wall. Laser blasts reply as Super Sonic seems to dance for a moment, the flashes of crimson missing by a hairs breath before one hit by pure luck, sending the chaos powered fighter into the air to tumble four times before plowing into the floor.

The energy spikes lighting up the air like a spotlight as the battle rages on, if anything becoming far more fierce in the process.

A roar filled the room as both combatants seemed to pause in mid motion as they got to their feet, realizing that Acaltha could destroy them both. The danger is real, but neither warrior seems to care, their thoughts quickly snap back to the other as they reach their feet, blades at the ready.

Super Sonic lashed out with an impressive chain of strikes that moved faster than the human or even a slayers eye could discern, even the hedgehog could see little more than a blur. Explosions of metal on metal rang out above the low roar and rumble of the demon coming to life.

"Your weakening," Cyber Sonic hissed, "give into it, I'll make your end quick."

"Never," the glowing one retorted, releasing another wave of energy, "And as for weakening, so are you, how does it feel to have that organic part now?"

"It gives me the advantages of both, I am the ultimate life form in this universe!"

"No, you have no idea what you're up against," Super Sonic said with a smile crossing his lips now, the brief pause allowing him to draw out a pair of Power Rings, "And this will let me kick your ass!"

The two rings seemed to dissolve into a glittering dust of pure energy that circled Super Sonic and the Sword of Acorn, infusing both, the blade activating with the infusion as never before and the glow of the hedgehog seemed to increase, the ground shaking under the red shoes with a white stripe on each.

"Play time is now officially over," Super Sonic chuckled as he charged the cyborg warrior, power flashing all around him, "Chaos Control!"

The light seemed to grow as both hedgehogs seemed to vanish for a mere instant and then reappear with a sickening thud as Cyber Sonic was slammed into the wall.

"You opened it, your blood will close it," Super Sonic hissed at the other one.

"Check again," Cyber Sonic sneered back, both blades locked together, but Cyber Sonic's starting to crack against the powered up Sword of Acorn.

The glowing hedgehog saw the bloody smear of a handprint just below the guard, but before the blade. His eyes trailed down the weapon, spotting the blood coated glove of the cyborg and then to his own shoulder where the injury was still visible.

"No," he whispered.

"Oh, yes, even if this shell is destroyed, I win, you have to destroy yourself," the pale blue hedgehog laughed as Super Sonic released him to collapse to the ground as the other backed away.

The cyborg clutched at his throat, coughing as it gasped for air, the golden hedgehog backing away, slowly. His white gloved hand reaching up and touching the wound, it was sealed but, the thought died right then and there.

"No," he managed to get out again.

Cyber Sonic climbed to his feet, shifting its blade to a two handed grip and lunged.

Super Sonic lashed out with a devastating blow that sent the cyborg tumbling out of the pit and out of sight just before he dropped to his knees to try to force his brain to think of something, his eyes drawn to the portal that was just beginning to form in front of the stone monster.

The speed freak had a simple choice to make now, his memory flashing back to the words he had heard; the blood that awakens it needs to close it.

He could do nothing and let the portal destroy everything, or he could sacrifice himself to save the world, being destroyed in the process.

His choice now, and his alone as he launched upwards, his heart heavy, but he knew deep down within what he had to do, and that it was the right choice.

His eyes scanned the pit and those around it, momentarily spotting Cyber Sonic, unconscious hands sparking as well as several other spots, under a shattered light, the electric charge having shorted out the half biological, half technological nightmare leaving it twitching, but neutralized.

His eyes locked with each of the others as he slowly shook his head.

"I'm sorry," he managed to say softly, meaning it as his mind flashed through what had brought this event, what had made it happen.

The spell that gave Xander the power to become Sonic, the destruction of the statuette after the Emeralds drew power from the god of chaos. The fall of the Judge and Angelus. Janus bringing Silver Sonic to the Hellmouth, Vaulk, and now this, one last time to be the hero, one last option, his decision was made.

Buffy and Willow saw the look in his eyes, the eyes with no emotion, no fear, no doubt, no pain, no hope, no love, the look of absolute sacrifice.

"No," Buffy managed to choke out, moving towards the hedgehog, but stopped by the others.

"Please no, Xander, don't go!" Willow screamed as the speed freak's eyes met hers for a moment.

"I have to," he responded, tears coming from the warriors eyes as he prepared himself for what was to come, "Well, I guess that this is Game Over."

And with that final statement, Super Sonic dove, sheathing the Sword of Acorn as he did it, drawing out all of his energy as he did so, Sonic accelerated, becoming a streak of light that burned into the memories of those watching, only light for a mere moment.

"Look out you freak, here I come," Sonic hissed the instant he hit the portal, the instant before an event that would reach the news all around the world.

The demon began to shake as the portal began to die down, a glow of the raw energy jammed down its throat exploding like an atomic bomb, shattering the petrified demon and throwing the Scoobies backwards and away like rag dolls, and all of the windows as far as LA shattered instantly. Night became day as energy surged through the tunnels under Sunnydale burned brightly, vampires catching fire from the pure energy the sacrifice had released, dusting them instantaneously, above energy seemed to burst forth, power lines surging and junctions busting. The vampires prowling the surface died even before their underground counterparts.

The stream of light was visible from orbit the mere moment it existed, but within the atmosphere, it remained daylight as if it were high noon for hours, people waking to the miracle.

The guardian smiled to himself slightly, his chosen had done it, succeeded where none else could. He had even managed to defeat a god with the victory, an unprecedented victory, but it also would have come with a horrendous cost, but that very power that had been drawn from Janus had changed the portal, tearing a chunk out of space time itself, destroying the hell dimension that he would have ended up in, the portal acting as a magnifying glass to the power surge.

His chosen was alive, he could feel it, the question was not that though, but where and when the hero of the hour had ended up at.
