If you have battled Rotom, you can try to capture Heatran in Stark Mountain, if you haven't unlocked that side quest yet. You can do many things after defeating or capturing Rotom, such as; trying to complete the National Dex, capture new Pokemon using the PokeRadar, defeat the Elite Four, and so on. Rotom is not a requirement, so there isn't any story unlocked after encountering Rotom.
you can't, unless you are wi-fi battling someone who has a rotom
go to the old chateau. in one of the rooms, there is a tv. click the TV to get rotom in battle. this can only be done at night
Go to the Old TV in the Old Chateu between 8pm and 4am. Rotom should come out of the TV and battle you.
rotom, you go to the cheateu thing in the eterna forest after 8 pm and talk to the tv and you will battle rotom
Rotom is no. 152 you have to go to the TV in the Old Chateau at night and bump the TV Rotom will come out and battle you at level 20.
You can catch rotom by going in eterna forest and going in the house but you need a Pokemon that knows cut and when you get in the mansion you find 5 rooms and you go to the one on the nearest left and you click A on the TV and rotom will come out to battle
To catch Rotom, go to that forest and go into the old house. Go to the top floor, and into the hallway with a bunch of rooms. Go into the room with a TV in it. (has to be around eight o' clock at night) and talk to the Tv. Then you battle Rotom.
go to the old chateu in entera forest. Go upstairs, in one of the upstars rooms, there is a t.v, go up to it and hit the A button. Rotom will be in there battle Rotom until it only has one HP left, then use a dusk ball or an ultra ball to capture Rotom. Hope this helped!
You can get Rotom at the Old Chateau in Eterna Forest. Go to the room with the TV. Press A on the TV, and it will ask you if you want to bump the TV. Say yes and the Rotom will come out and battle you so that you can catch Rotom. (You need to go to the Old Chateau between 8pm and 6am.)
At a certain time in the middle of the night, go to The Old Chateau in Eterna Forest. Go to the room with the TV, and it will ask if you want to thump the TV. When you do, you will begin the battle with Rotom. I suggest you save before you battle, because you only get one chance to battle him, and he's weak. Hope this helps! :)
First you need to trade Rotom from Pearl, Diamond, or Platinum. (Rotom is at the Old Chateou which is at the Eterna Forest. Go there after 10:00 pm and press a against one of the TV's, Rotom will pop out and you will battle. Rotom is at lvl. 15 and is Electric Ghost.)(Pearl,Platinum,Diamond) make sure Rotom is the first Pokemon in your party, when you do that the elevator will take you up to the next floor when you will see items that you can give to rotom to change it's type. items: Fan Rotom - Electric Frost Rotom- Ice Heat Roto- Fire Mow Rotom- Grass Wash Rotom- Water
go to the battle fronter and win 7 straight battles and then the will throw out pokeball aka boring as.;.
