No one knew how it had happened. Today's biologists were baffled. However, as far as they could tell 3.35 billion years ago their DNA had been tainted. The amino acids, the building blocks of life, had been given different instructions. They formed protein, but instead of that eventually creating just human life... well... it created something that could only be called 'different.'

No one knew how it had happened. The best scientific minds could only gather it had been the work of a meteor, bringing foreign particles that interfered with the 'primordial soup.'

However, what's done is done, and no one really bothered about it anymore.

It was normal.

Aaron Hotchner looked in the mirror. His eyes still contained a hint of red, seeping into the black that was the usual colour of his irises. His face was chalky white, but colour was slowly returning, and he felt a warmth running through his veins as the blood was absorbed by his system. He looked almost human, and briefly he saw the man he used to be... before it had been stolen from him.

By law, creatures were 'encouraged' to have a somewhat normal appearance. It made the humans feel safe.

Hotch wondered how safe a powerless human could feel in a world mainly populated by 'monsters.'

He certainly never felt safe, and he was considered one of those 'monsters.'

Moving from the bathroom, he entered his bedroom before kicking his shoes off. Flopping down on his bed, he closed his eyes.

His day had just begun.

Derek Morgan ran across the fields. Wolves circled on either side, and charging through the undergrowth he matched their speed. The night was cold, unseasonably so, but as they ran, he could feel none of it.

The fur was good for a reason.

Howling, the moon came into view, peeking out from behind obsidian clouds, and they doubled back. He was almost in the lead now, and snapping at the other's heels, he swiftly over took, leaping into the air in victory.

It wasn't the most conventional way to ride out the transformation. However, they all heard about the werewolves that had to be 'tamed' when under the influence of the full moon, and none of them wanted to be in that position.

Running was by far the safest way to burn up the excess energy produced from the metamorphosis.

And he was winning. Looks like he was going away with the fifty dollars this time.

Jennifer Jareau was smiling. Cupping the water in her hands, she felt the icy cold run through her veins. Extending it towards her hands, she watched as the water rose, snake-like in front of her. As it rose up, she swallowed it. Not the most conventional way to take a drink, but it was nice to use her powers for something.

Henry laughed, clapping his hands together as he watched his mommy do tricks. Will smiled at her, taking in the sight of his wife and their child. He was human, but as far as he was concerned he was the luckiest human in the world. Part of him hoped that Henry would inherit his mommy's abilities, apparently signs were meant to have shown by now, but he still lived in hope.

However, as far as he was concerned he already lived with two magical creatures.

David Rossi sipped his drink, feeling the burn slip down his throat. Smacking his lips, he played his hand, trying not to laugh when it was met by groans from his fellow poker players. Gathering the chips, he stacked them up, mentally calculating how much he had won so far.

Hmm, about a grand so far. Yep, better split.

Draining his glass, he placed it back on the table, rising nonchalantly at the same time. Glares met this move.

"Right boys, better be off. Have a round on me," he said, throwing a twenty on the table.

Seeing appeased looks, he hid a smirk. A free drink quenched anyone's rage. Taking his winnings to the converter, he left the casino a wealthier man.

Sometimes being psychic was brilliant.

Emily Prentiss. That name generally carried dread, as well as a few curse words. Right now, she heard a few of those words coming from her pursuers. Jumping onto another roof, crawled along it, losing herself in the shadows.

It was dark, oh so dark. But she wasn't scared.

She was the darkness.

Hearing her hunters pass by, she rematerialised, seeing her pale skin stand out from the night. Leaping off, she landed catlike on top of a dumpster.

Sheathing her bloody dagger, she tidied herself up. If she was caught like this she may be prosecuted.

Humans never liked differences. Well... they never liked being reminded of their inferiority.

Then again, if her Hotch found out about her 'other job' he would probably freak out even worse.

Now that would be entertaining.

Penelope Garcia. One might already think she is an android. Her knowledge of computers certainly made it seem so. No, she was a fairy.

Now. That. Wasn't. Macho.

She wanted to be a vampire, a slayer, hell she would even be a werewolf!

Fairies were small, they couldn't fight. A slayer could have a whole village dead in under ten minutes.

Instead she just immersed herself in computing.

She wanted to be the best. In fact, she was experimenting with AI, but R31D wasn't co-operating yet... Okay, she just couldn't get the filter right. When she asked him a question all he would do is unleash a barrage of information.

Maybe it was just one of his quirks.

Sighing, she ignored the raw deal she had been given by evolution. Plus, she could do some cool things.

Flying through the corridors of the BAU, she slid under the door to Hotch's office.

Surely the man wouldn't notice if a thimble of his scotch went missing.

A/N: I've recently immersed myself in supernatural fics, and I really, really wanted to write one. Please tell me if this is dire - Urgh, I hate first attempts. Excuses aside, this will have humour in it, I know it doesn't say on the genre, but they really should allow us to pick more than two! This is just the prologue, getting to know a little bit about their world, the next chapter will introduce a case, and then blast off :D And... I really have nothing else to say except 'please review!'

DISCLAIMER: I do not own Criminal Minds, I just like to play with them *evil grin*
