after Celebi sends you into the past for a third time you can do "multiplayer" missions in the past (you can do them alone but with a friend is faster also the missions have a time limit), some of these missions involve battling the Pokemon on the slates and when you beat them and go back to the future the slates will break opening a the path for you.
When the respective bosses are beaten in the past missions, the slates will crumble.
They have Pokemon behind them, but to open them you have to complete missions on ranger net ( their not legends or special Pokemon just ordinary ones.)
