Thanks! Well, I believe I haven't yet posted a storyline, so here's the resumed one (sorry if I already posted:P ):
"Many years have passed since the terrors of the legendarys and Rockets ocurred.
Now everything's in peace, and the people and even the world itself is in Happiness.
Today, you leave to be the World Pok?mon Champion, and to honor that happiness.
But beware...evil forces are near, trying to shatter this happiness..."
