Well in the early RP the plan was to have most of the story going on in the human world. While in the Pokemon world a lot less is going on. Ideally your character would be from the human world for several reasons not least that this would give them greater motivation to solve the problems in the human world. Later on I think I may open SU for both worlds but most of the early plot will have gone by then and there will be different rules regarding powers. Anyways it's up to you to decide what you want to do, I could properly find a way to work it in to the plot now but I would need your character to do several things right away.
