Okay, let's try a new story.

I don't own any part of the Sonic the Hedgehog franchise.

So, read, review, and enjoy.

Shadow slinked through the dark alley at midnight, enjoying the silence; it allowed him to think in peace. He had to think about how he felt. Over the last few days, he felt unusually hungry and he ate so much to try to stop the hunger, but it only made it worse. Feeling a pain in his gums, he ran his tongue over them, but nothing seemed different. Sighing, he closed his eyes and shook his head to get rid of the annoyances, but they still lingered. "What is going on with me? Why am I feeling like this?" he pondered silently to himself. "What could be causing this?"

Opening his crimson eyes as he heard some girlish giggling, he stopped and looked to see a teenage boy and girl passionately kissing each other against a wall near the entrance of the alley and Shadow gave a confused look as a strange sensation came over him. He could hear their hearts pumping blood as clear as if he was standing right next to them with a stethoscope and his gums were aching more than ever as something sharp seemed to protrude out of them. The longer he heard the noise, the more he felt like he was fighting to urge to attack both of the teenagers and he held his head and shut his eyes tightly, trying to block the noise out, but it only got louder. Unable to resist the urge any longer, Shadow's eyes opened as he rushed down the alley and tackled the teenage boy to the ground and felt a set of fangs extend as he sunk his teeth into the teenage boy's neck. Feeling an addicting rush as he felt the teenage boy stopped struggling and become limp and his hunger being satisfied slightly as blood flowed down his throat, he looked up to see the teenage girl wearing a shocked look as she let out a high pitched scream. Getting to his feet, Shadow once again felt the urge and pounced on the teenage girl, her screams subsiding as he sank his fangs into her neck and drank her blood, not stopping until the hunger was filled and she was completely lifeless. Feeling his fangs retract as he pulled away from her, Shadow wiped his mouth with his arm, able to catch a glimpse of blood on his arm. Remembering the substance that satisfied his hunger, he lapped up what was on his arm, savoring the taste. Looking between the two dead bodies, his crimson eyes turned a mixture of shock and fear as he thought, "What have I done?" He pieced everything together before he stood up and quickly rushed away from the bodies. "It's impossible…I can't be a…a vampire…"

There's the chapter.

I know it's not the first fanfic of this sort and it's pretty short, but I hope you liked it anyway and please review.
