I think it is like this: Choose one of the persons from the pokemon series, like Ash, May, Sabrina, Brock... And write down the pokemon you would have (as them). Then you should be able to battle each other with the pokemon, as the characters. Pokemon battle and rpg in one, I guess.
Be a person and pick up to 6 pokemon 6 maximum and choose the person you want to battle. Like if I said GregByte then we would battle, say the pokemon's name we sent out and then we say what move we want to use.
Wow this is pretty pointless because the start had mostly a lack of explanation if this had a better explanation and not just "Pick a person from pokemon..." which barely is an explanation at all!
