If Pokemon does exist, I'd be afraid to fall asleep. If you want to know why, look no further than my pick for the most terrifying one in existence. This Pokemon is a Nightmare...literally. My pick is...

Darkrai!

Darkrai is almost similar to one of my favorite horror movie characters of all time, Freddy Krueger. In fact, if Darkrai starts killing people in those dreams and, in effect, killing them off in real life, he'd be Freddy in Pokemon form.

Darkrai as Freddy Krueger? Hmmmm...

Pokemon: A Nightmare In Vaniville Town confirmed?!

Imagine the song the little girls will play:

One, two, Darkrai's coming for you

Three, four, better lock your door

Five, six, grab your crucifix

Seven, eight, gonna stay up late 

Nine, ten, never sleep again

...

Shoot, now I really want to write this story!
