This is a thread where you get to make up secret backstories of the characters. Things the characters would ordinarily keep to themselves. For an example, when Ash was 7, he was lost in the forest and taken in by a cult. A cult known as the Foot, a group of ninjas who want to rid the world of Pokemon. He was trained in their ways and became apprentice to their leader. And for a time, after seeing how the Foot do things, Ash began to enjoy it. But soon, he decided he couldn't take anymore. So he abandoned the Foot and returned to Pallet Town.
So just have fun with it.
