Visit the Old Chateau after obtaining the National Dex during the hours of 22:00 and 4:00, and then go into the room with the TV. Check out the TV and you might encounter Rotom (if not, try again later). (Only one.)

Answer 7

yeah you need national dex to find it. which pokemon is it you need? if it is the other legendary, go to cynthia's mother in one of the houses in celestic town, she will show you it. then get the dex from rowan in sandgem, then go to the tv in the old mansion between 10 and 4 at night. if it doesn't work, go back an hour later until it does come out
