At night, go into the Old Chateau in Eterna Forest. In a particular room, press A while facing a TV to battle Rotom.
Rotom can be caught in the Old Chateau (In the forest north of Floaroma Town). To get it to appear you need to go to the tv inside the Chateau at night and inspect it.
No. Rotom does not evolve. But if you have an action replay, you need to use it to get the secret key. If you get the secret key go to the Team Galactic Building in Eterna City. Once you enter, Go all the way to the left and go up. Press A on the wall and the wall will turn into a secret room. Enter the room and you will see 5 motors. Rotom can go into them one at a time. But you can use the action replay to get more rotoms so you can have all the forms!
