Okay then...
At exactly 3:00 AM, serveral pokemon from different parts of the word disappeared, including YOU! You wake up in a strange new place full of toxic swaps, flaming forests, and mountains of ice. In this strange new place, there are places where you can defy the very laws of physics, and places where the laws of physics defy you. When at first you wake, your confusion causews you to panic, but all is explained in the form of a voice that echoed all throughout this strange new place.
"Welcome, welcome, to my humble abode. I've decided to hold a little tournament, and you are the contestants. Though I am the only spectator, I still expect you all to put on a grand show. As of now, there are 12 contestants in this little piece of hell, and only three will return to their humans alive. The other 9, not so fortunate. However, if there are more than three contestants left after one month, or I begin to get bored beforehand, I will not hesitate to use the Grand Finale I have planned, and none of you will survive. Oh and one more thing: My home is a little incomplete at the moment, so don't wander far. Hehehehahahahaaaa..."
Will you survive this strange new place?
