Fight for peace

A long time ago, all the world's lived peacefully. Although not all the worlds knew about each other, everyone lived as peaceful as they could in their respective worlds. And in one of these worlds, almost everyone had supernatural abilities which were powered by substances called rubidstones. Each rubidstone lived inside it's wielder and revealed itself when the wielder wanted it to. Rubidstones only chose people who are pure of heart and a new rubidstone was created once a worthy person was born. And because of it, that world was the most peaceful among them. But one day, a wicked ruler at the far end of all the worlds rose up and decided to broke the peace which the world was living in. He went to that universe with his army of tundumons. Unknown creatures which looked like wolfs but had hands and stood on their hind limbs. Lots of lives were lost that day. But one man was able to change everything. He took the rubidstones he had gathered and escaped to a different world (earth) and spread it across the earth hoping to fulfill a prophecy that was told a long ago. And it said;
"One powerful and evil person will rise up and disrupt the peace which all the worlds are living in. And when he's close to victory, one man changes everything. He won't be the one to bring back the peace though, but through him new heroes will be born. And among these heroes, a young boy will take up the responsibility and restore peace once more. He will fight with a motto that said, 'fight for peace'"
