Hello! I know there was an issue with this story before (I uploaded the wrong document) but it's back and I swear it's the best (and only, so far) crossover I've written yet! Enjoy!

There are seven Gems of Reality

They are emeralds, though not of this world.

The first, a green gem:

The Gem of Life

The second, the red gem:

The Gem of Strength

The third, the yellow gem:

The Gem of Form

The fourth, the light blue gem

The Gem of Visions

The fifth, the dark blue gem

The Gem of Dreams

The sixth, the violet gem

The Gem of Control

The seventh, the white gem

Is the most powerful of all. It is the power source, known as the

Gem of Power.

When all seven come together, they create a miracle

However, the only way to obtain them requires battling many adversaries,

Particularly the ghosts, far different on Mobius than on your world . . .

My name is Sonic Daniel Hedgehog, but I go by Sonic. I have a sister named Sonia, and my parents, who everyone knows as Mr. and Mrs. Hedgehog, as they do for most adults, are nuts. Why do I say that? Well, they're obsessed with ghosts. Their job description is "ghost hunters." And guess who they tried to take along on the ride every day for his entire life?

"Sonic! Check out our newest invention, son!" That was my dad, the one who looks like a really old version of me with a mustache. I groaned and followed him to our lab/basement. Normally I avoid it.

There was my mom, wearing her goggles and getting to work. In the side of the wall there was a high-tech tunnel with a lot of green lights and such built in. A lot of wires were attached to it, and I noticed that they all connected to another supercomputer of theirs, pushed up against the wall.

"It's a Ghost Portal! When we get it working, it will open up into the Ghost Zone!" I sighed. Another one of my parents' inventions that would probably never work. It was apparently a big one, and I knew that they would be really depressed if (ahem, when) it didn't work. (My dad was always sad enough when we didn't have fudge or chili dogs in the house; this would destroy him.) I watched my parents work away at it, and, when Mom plugged it in, it sparked a little, but that's all. They both looked like they were going to cry, but said nothing and walked upstairs. I immediately called Amy.

Amy and Tails are my best friends. Tails is the ultimate in computer nerds, and Amy could possibly be described as bipolar. She was passionate about what she believed in, though, and that included a lot of environmental things like recycling and saving endangered species. Tails always whispered, "Aw," behind our backs like we were a cute couple, but we've been friends since first grade. Freshman year at Emerald High would not change that.

Anyway, they both showed up in minutes. I led them downstairs, and showed them the portal, explaining how my parents were so upset.

"Maybe you can get it to work, Tails?" I asked hopefully. He shook his head.

"I doubt it. The computer is probably fine, it's the scientists that I'm worried about . . ." Both Amy and I glared and he stopped.

"Maybe there's something wrong on the inside of that tunnel?" asked Amy. I started to walk towards it, but Tails grabbed me first.

"I don't know, Sonic. It seems dangerous." Amy scowled.

"Tails, be quiet. It's his decision; if he wants to go in, he can. If not, I'll do it." That made up my mind. Amy was not going into the deathtrap that my parents made. I was. I thought as I held her back from it, I swear, I'm not going to let anyone get hurt if I can help it.

A word about ghosts here on Mobius, before I continue. According to Mom and Dad, the way to distinguish a ghost from a living person is to see if they have a slight white glow around them. And, if you want to know who they were before they were a ghost, they often will not tell you. It's easier to just compare looks. All ghosts have obsessions, whether it was revenge or cookies or anything really. There was a theory about half-ghosts that I don't remember a lot about, partially because I fell asleep during the long-winded lecture. You never know too much about them, because obviously it's a little hard to find something that most people don't believe in. But that's the facts that I know. Back to the story.

I stepped into the tunnel and immediately knew two things: it was dark, and I didn't know how long it was. I reached out to feel along the wall, and as my hand slid across the slick metal, it hit something, and I heard a click.

Green sparks started to glow around me, and the metal began to glow white. I looked at where my hand was and found the "on" button. I cursed my dad for being a bit of an idiot, and thought one thing as my body began to feel like it was on fire: At least I protected Amy from this. Then it began.

I will never really know how long it was, but I did know that I wanted to die at that moment. It would be a lot more relaxing than what I was feeling. If you'd been struck by lightning, or set on fire, or shattered nearly every bone in your body, put those three things all together and multiply that pain times ten. That's about how much I was hurting. I was screaming, and that's probably the only sound that I could hear for however long it may have been. I didn't notice that I blacked out until I opened my eyes, realizing that I was lying on the lab floor. I sat up, feeling sore but surprisingly not in pain.

"Amy, Tails, what just happened?" I asked. My voice was probably hoarse from all that screaming, because it came out low and rough. Both of them were standing five feet away, looking at me like I was about to kill them.

"Why are you looking at me like that? What happened?" I asked. Amy blinked, and shivered.

"S-Sonic? Is it really y-you?" she asked. I furrowed my brow.

"Who else would it be?" Both of them were staring, not scared now, but immensely sad.

"Sonic . . ." I looked at the tunnel, seeing that it was green and glowing, but there were no other things visible in it. Then I got up and looked at the supercomputer screen, which was turned off, so I could see my reflection.

I might as well have screamed again.

Rather than a blue hedgehog with green eyes and red sneakers, like I expected, I saw a completely different thing. It was a black hedgehog that was a little more tan than me, with red highlights on his spikes. His chest fur was white, and he wore high-tech skates instead of sneakers, and his gloves were slightly different than mine. It wasn't even his white glow that freaked me out at first, but his eyes. They were scared, just like mine, but rather than the green I was so used to, they were a blazing blood red.

"Am I dead?" I asked incredulously, looking down at myself to see that the reflection was real. My two friends didn't answer.

"Sonic . . . I'm so sorry!" Amy started to bawl.

"What for?" I asked, hugging her close.

"I pretty much killed you, you know. I-I feel so horrible!" She sobbed into my chest, and I looked at Tails. He actually snickered and muttered "Lovebirds"! I pried her off of me.

"Amy," I began. Suddenly, I growled in my head. Ah, why can't I be a normal hedgehog again! Suddenly, an iridescent flash of light surrounded me.

"Huh?" I looked at the computer screen again, fearful that something somehow worse had happened—but I was me again!

Amy was still crying, not even looking at me. I pulled her chin up, and she stared, shocked.

"Sonic?"

"Yeah, Amy, I'm here. I don't think that I'm dead. I think I'm half ghost—it's something that my parents told me about once. I don't remember much except that it means that I have a ghost form and a normal hedgehog form. Maybe we should come up with a name for my ghost half . . ." I was so relieved that I wasn't dead that I hardly cared that I was half-ghost. I was just happy enough to be alive.

"It should start with an S like your real name, shouldn't it?" asked Tails.

"Your other half . . . hm . . . what about Shadow?" asked Amy. Both Tails and I nodded eagerly.

"Yeah . . . Shadow the Hedgehog . . . I like it!" I said. And so began our adventures.

And that was the introduction to this lovely story! (hehe, you didn't see that one coming did you? Sonic and Shadow the same person! Ha! It's pure genius if I do say so myself.) Anyway, please review, and tell me if you think I should continue. By the way . . . check out my other stories if you get the chance! I'd appreciate it!
