Okay. Last chapter was the prologue to the fic so I shouldn't expect it to get popular or anything. ^^;; This is what happens when you're away from Fanfiction for so long! XP Anyway, here's the first chapter! Please note that this takes place during the Sonic Adventure DX events.

Disclaimer: I don't own either Naruto or Sonic!

A blue streak zoomed past several city buildings, then jumped from a car to the roof of the lowest building, which happened to be a bank. The streak had ended, and standing there on that rooftop was a blue hedgehog.

Sonic the Hedgehog.

He smirked at the cityscape- having left it behind three months ago and had just returned from his last adventure today-, and stretched his arms out. The said hedgie took in one deep, relaxed breath as he reached the end of his stretch, then said, "Ooooooh yeah! This is happening!"

As he kept staring out at the city, police sirens passed by the bank, alerting the hedgehog and causing him to gaze over at the black and white emergency cars making their way down the road towards city hall. Sonic became curious. 'I just got back and there's already trouble?' he thought as he leaped off the building and landed on the ground. "What's up?" He scratched his head, wondering for a second, then sped off in pursuit of the police.

Police cars were parked near the city hall building with the police officers out of the vehicles, readying their guns. They had received word that a strange and mysterious figure was seen near city hall, so they went over to investigate. Once the police stepped foot on city hall grounds, one of them looked up.

"Look there!" he called out. The rest of the officers looked up at this point; what they saw was something that no one else had ever seen before.

A light blue, liquid-like, humanoid figure was standing on the roof of city hall, slightly looking down at the bemused police officers. It leaped all the way down to the ground, landing on both of its feet unharmed. It didn't do anything, though… just stood there staring at the police with it's big green eyes.

The said police officers backed up a few steps, loaded up their guns, and pointed them at the creature. "What is that thing??" asked one of the officers. The head police officer looked over at the officer that asked the question before turning back to the creature.

"Whatever it is, it'll pose as a threat if we don't do something!" he said. He then said to the creature, "We have you cornered! Put your hands up in the air nice and slowly or we'll shoot!"

The blue creature didn't say anything for it had no mouth, nor did it do anything. It just kept staring at them as if it was waiting for something.

"I repeat! Put you hands up in the air and we won't shoot!" the officer repeated. Still it did nothing. The head officer turned his head to the other police, then gave the order to shoot. All of them fired at once repeatedly at the creature.

When the last bullet was fired, the blue creature was still standing there unscathed. The many bullets that had hit it fell to the ground. There were no wounds where the bullets had hit. They didn't even leave a dent in him!

The head police officer cursed under his breath. "Our weapons are useless! Fall back! I repeat, FALL BACK!!" he ordered and the police didn't hesitate to retreat.

Once they were out of the creature's sight, it looked triumphant (though no one could tell since it had no face expressions.) for a while. Before it could walk off, someone called out, "Hey you!" The creature turned around, seeing an azure hedgehog standing where the police once were. Its eyes narrowed at him.

Sonic readied himself just in case this creature did anything. "So you're the one who had the police high-tail it?" he asked. It didn't reply. Sonic waited for a reply until finally, he said, "Huh, not much of a talker are ya? Well then, prepare yourself!" With that, he charged at the creature at full speed and leaped in the air for a Homing Attack.

The said creature looked up, then leaped out of the way before the hedgie made contact with it. Sonic charged again, going for a Spin Dash this time, only to find out that the creature leaped out of the way again, landing on one of the nearby light posts. Before Sonic could attempt an attack, the creature stretched its liquid-like arm and struck him in the stomach.

The cobalt hedgie flew back a few feet, then landed on both of his feet, looking very impressed by its actions. He whistled in awe. "Hey, not bad." He said. Once the creature was on the ground again, Sonic Spin Dashed it, whirling around and around it, trying to make it dizzy. He then ran up the city hall building and did another Homing Attack, landing the blow to its noggin where its brain was obviously seen through. The creature's body burst like water, then formed on the ground as a puddle.

Sonic landed on his feet, staring at the puddle for a long time. Suddenly, the puddle moved, slithering towards a gutter. Sonic pursued it, saying, "Hey you big drip! Where do you think you're going??"

The puddle stopped in one spot, then like water, it poured down a drain into the sewers.

"What the…" Sonic stopped and stared at the drain for a long time, the dark clouds hanging overhead poured the long-held rain that was now beginning to drip down on the city. Sonic looked up at the sky, sighing heavily.

'What was that thing? I've never seen anything like it before…' he thought. Nothing else seemed to come to his mind at this point. He'd have to talk to his little buddy Tails about this.

"Maybe tomorrow." He said to himself. He then turned and began walking away. As he did so, a bright white light shot up through the holes of the drain. The ground began to shake, alerting the cobalt hedgie. Sonic stopped moving and spun around, his attention on the light coming from the drain. The quake became bigger and the light intensified its brightness, causing Sonic to shield his eyes. A sound was then heard. It wasn't the sound of the rain, nor was it thunder or lightening.

There were no ducks or birds because of the time and weather, so it couldn't have been that. People were already inside and there were no cars driving by. No. This sounded like a scream. It was a quiet scream, but as the quake started to subside, it grew louder and louder. Soon, Sonic could identify that the scream belonged to a female. He knew it wasn't Amy's scream, for this scream was shriller than hers.

He then uncovered his eyes slightly and saw a humanoid figure fly out of the drain and into the chilling air. The light then faded until there was no more light left and the earthquake long since subsided. The true blue hero uncovered his eyes, immediately looking up to see something (or someone) falling down from the high altitude, her screams getting worse now.

He didn't have time to think, so he ran up the city hall building, and leaped off it, aiming for the falling figure. In a second, he caught her in midair and landed gracefully on his feet. When Sonic sighed in relief, he gently put the girl down. She had stopped screaming and was now clinging tightly to the blue hedgehog, shivering and whimpering in fear.

Sonic gently pried her off of him and pulled back, taking in her appearance. She was a cat with light pink fur, emerald green eyes, and had a head of bubble gum pink hair that touched below her shoulder blades. On her body, she wore a red top, black shorts, a pair of brown sandals, and holding back her hair was a headband that the cobalt hedgie had never seen before. He also took note of her high forehead and a pouch that was strapped to her left leg.

Tears had formed in her eyes and were falling rapidly down her face. She blinked once, then once again started to cling tightly onto her savior, crying her eyes out. All at once, the slender pink cat began to repeat over and over, "Oh my God. Oh my God. Oh my God!" After that she tearfully said, "That was so scary!"

Sonic sighed heavily, not knowing what to do. He pulled her away from him again and asked if she was okay.

The said cat girl was about to answer, but her expression immediately changed from fear to confusion. She leaned in on the blue hedgehog's face, examining very bit of it. Then she looked him from head to toe and ran her fingers across his bare chest and his quills. These actions really disturbed Sonic, so to make her stop he grabbed both her wrists and pulled them away from his body.

"Um. Would you stop that?" he asked, slowly letting go of her wrists. "It's making me nervous."

The cat girl suddenly looked alarmed and jumped back one foot away like she had just seen a ghost. She took in a few deep breaths and thought, 'That's a hedgehog, right? But… it talked!!' "Th-Th-That's not possible…" she said softly, but loud enough for the confused hedgie to hear.

He slowly walked up to her, asking, "What's not possible?" The cat girl backed away again, then started making strange hand signs. Sonic wasn't familiar with the signs she made, making him tilt his head to one side. Once she finished making the hand signs, she called out some sort of attack.

But it never came. Confused by this, she did it again using the same hand signs. Again nothing. She did a different set of hand signs and still nothing. She then reached in the pouch, feeling around in it for some kind of weapon. When she pulled out her hand, though… nothing!

"But… how?" she asked herself, staring down at her hands. As she did so, she noticed something different about them. Her hands were light pink and furry! Those same exact hands slowly reached up to her head, feeling a pair of cat ears, which twitched to her touch. Finally, she automatically reached behind her, grasping a long, smooth light pink tail.

It took a while for it all to register in her mind……. then she screamed at the top of her lungs. Sonic had to cover his ears because she was so loud!

"OH MY GOD!! WHAT THE HELL HAPPENED TO ME ~NYA?!" she screamed, but then stopped and covered her mouth after saying 'nya'. "What was that ~nya?" Her left ear twitched and she covered her mouth again.

Sonic slowly and cautiously walked up to the cat girl, putting up his hands and saying, "Just calm down." over and over. But she didn't calm down. Instead, she stared at nothing for what seemed like hours, and then she fainted due to shock and stress. Sonic caught her as she fainted and picked her up bridal style. He looked her over a few times, pondering on what he should do. "Hmm…" he said, then sneezed. Looking around now, he had forgotten that it was still raining and was getting soaked to the bone!

Sonic sighed. "I need to get outta this rain." Then he dashed off, carrying the pink cat with him. Little did he know, however, that someone had been watching all that from nearby.

Whew! Another chapter done... For those who are confused about the 'nya's, it'll be explained... eventually. Hope you all enjoyed this chapter! ^^
