umm is it giratinia
because it is a dark pokemon that is very evil i guess
Sigh.
Since this is going no where I will reviel the pokemon, you will need to give the description to win:
Giratina.
Since Cody587 guessed the pokemon, s/he will win if no one gets it in two days.
Sorry, I haven't a clue why it is called the devil. I don't see all of the pokemon shows so I guess I am out of luck. Wish I did, cause this is a hard quiz question.
