Ok, so this is my first story ever on this site. Sorry if it sucks, I'm not all that great of a writer. This is a Generator Rex fanfic, about a powerful girl who is sucked into Rex's dimension- basically, it's like the Ben10/ Generator Rex heroes united thing, except I'm replacing Ben with my own character, and the plotline is completely different.

So... enjoy! :)

Disclaimer: I don't own Generator Rex, or any of the characters (besides Chelsea! ^_^), but I wish I did...

Chapter 1: Not Normal

Chelsea's POV

I am not normal. Never was. Even when I was a baby. Yeah, I look normal- brown hair, brown eyes- no signs of mutation there. But looks can be deceiving.

I've always felt like an alien, even though I was born on Earth. Sometimes I wish I was normal, but then again, my powers are the only thing that makes me special.

You see, I'm a sort of…shape shifter, for lack of better words. I can turn myself into anything, living or non-living. Heck, I could even be the computer you're staring at right now, and you wouldn't know it. I can also turn into any mythical creature, and any creature that comes out of my imagination. I can also grow wings out of my back, but stay in a human form. I go flying at night sometimes, just for fun, and just because I can. That's what I was doing the night my world was flipped upside down.

I soared above the pine tree forest, my eagle-like wings flapping hard to keep me in the air, and my long brown hair streaming out behind me, threatening to break loose from its ponytail. I glanced at my watch- 12:00.

"Dammit," I swore. I was supposed to be home by 11:30. My mom thought I was out with friends. I picked up the speed, catching a current of rising warm air, which lifted me even higher into the night sky. In the distance, I could see smoke pouring up into the sky.

"What the…" I dropped lower to the ground, trying to get a closer look. The smoke looked like it was coming out of…right about where my house was! I dropped lower to the ground, and retracted my wings, landing on all fours in the middle of the pine forest. I felt my body lengthen, my nails lengthened into claws, fur grew all over my back- I had morphed into a cheetah. I took off at unbelievable speeds, my paws barely hitting the ground as I ran. As I reached where my house should have been, I skidded to a halt. In its place was a smoldering pile of ashes. There was no living thing anywhere.

"Mom?" I called out, morphing back into my human form. "Dad? Sissy? Where are you guys?" I saw a piece of brightly colored fabric sticking out of the ruins. I pulled it out, blowing off the ash, to reveal a small piece of my baby sister's favorite dress- the one she had been wearing that day.

"Sissy…" a single tear slipped down my face. They were all dead, some sixth sense of mine just knew it. Somebody had burned my house down; this was no forest fire.

I scanned the surrounding forest, looking for anything that could tell me who had done this. I saw movement in the bushes, and a tall figure emerged.

"FREEZE!" I screamed. The man whipped around, and I saw it was Hawk- a man who had tried to blackmail my dad last year.

"I thought you were in jail!" I growled, my fists raised.

"I was- but I paid to get out," he snarled back at me. I could see his muscles bulging through the torn sleeves of his shirt.

"You did this, didn't you." I snapped. It wasn't a question.

"Yes. And I don't regret it." He threw his head back and laughed hard. I roared angrily, feeling my hands turn to paws, and the fur growing back over my skin- only this time, I was a tiger. I could see his eyes widen in surprise, but he quickly recovered from the shock and raised his fists.

"Come and get me, cat-girl."

I leaped at him, my claws dieing to shred him to pieces. That was when everything went wrong.

Rex's POV

"Rex! Watch out!"

I leaped out of the way just in time to avoid the tentacle that the EVO had swung at me.

"Thanks, Six!" I yelled. I activated my smack hands and slammed them down on the huge octopus-like EVO. It shuddered, and then sunk to the ground. I jumped down and placed my hand on its forehead, and healed the beast of its nanites. It shrank down, morphing into a baby octopus, which I quickly threw back in the ocean, so it wouldn't die for lack of oxygen. Six approached me.

"Nice job, Rex." His face showed no trace of emotion, but deep inside of me, I knew he was proud of me.

"Thanks! All in a day's work!" I laughed.

Suddenly, a blaring siren sounded from our ship. Dr. Holiday ran out.

"We have an emergency!" she yelled. Six and I looked at each other, then raced onto the ship. As the ship took off, she filled us in.

"A strange energy ball has opened up in the sky above Manhattan," she told us. "We don't know what it is, but we do know that it is destroying the city. Rex, everybody is relying on you to shut it down."

"Me? Why me?" I groaned. "Why can't Providence do it?"

"Because it could be some kind of EVO, and you know you're the only one who can cure EVOs."

I groaned. I knew she was right. I settled into a seat as the jet soared across the sky, getting closer to the new threat every second.

One Hour Later

We arrived in New York to find utter chaos awaiting us. A huge yellow ball of energy was shooting lightning at all the buildings.

"Whoah." I gasped.

I climbed up the ladder to the roof of the jet. I have to say, the energy thing looked ten times more terrifying up here- not that I would tell anyone that.

"Rex, be careful. We have no idea what this thing is." Holiday's voice crackled through my earpiece.

"Don't worry, doc, I got this under control!" I frowned. "Hopefully…"

I generated my Boogie Pack, and leapt into the air, zooming towards the energy ball. As I got closer, the lightning that had been steadily shooting from it seemed to subside.

"Rex, I'm picking up bioorganic readings inside the energy field. Something's coming out!" Holiday's concerned voice shouted in my ear.

As I watched, a form appeared in the core of the energy ball. It was round, and as I got closer, I saw it was a jet-black color. I waited in anticipation for it to come out. When it did, I was able to see what it really was. It looked like a huge black hedgehog the size of a 16-wheeler, rolled into a ball, and it was falling- straight at me. I dodged it as it came flying past.

"Rex, don't let that hit the buildings!" Holiday's voice gasped.

"Don't worry!" I yelled. I flew down below the creature and generated my Smack Hands. When it was directly above me, I hit it as hard as I could. It went flying towards Central Park, and I flew after it.
