Character: Rotom Zukan

Rotom, known as the Plasma Pokémon, is a small, floating Pokémon whose body consists of plasma, which can infiltrate electronic devices. They are mischievous, and wreak havoc on electrical appliances just for the fun of it. Pokémon Platinum introduced five new forms of Rotom: Frost Rotom, Wash Rotom, Mow Rotom, Fan Rotom, and Heat Rotom. Each form's appearance corresponds to a household appliance (a refrigerator, a washing machine, a lawn mower, a desk fan, and an oven, respectively). In the Pokémon universe, researchers are looking into Rotom as the power source of a unique motor.

Rotom are shaped like lightning rods, while the blue aura of electricity around them takes the appearance of lightning. Rotom's eyes and aura of electricity change colors when it changes form. Rotom's looks and abilities were inspired by Pulseman, a game that GameFreak worked on before Pokémon. Rotom is the word motor backwards; this may refer to the fact that motors make many appliances function, while Rotom makes them fail.

The only available Rotom in Pokémon Diamond and Pearl resides in a possessed television in an old haunted château. You can only catch him after 8:00 PM but before 4:00 AM. In North America, Toys R Us gave out Secret Keys, which unlocked Rotom's forms, via Mystery Gift from April 20, 2009 to May 12, 2009. The alternate forms of Rotom may also be accessed in Silph Co. in Pokémon HeartGold and SoulSilver. In the anime, Rotom made its debut appearance in Get Your Rotom Running! in all its different forms, toying around with Ash and friends. In Pokémon Adventures, Rotom appeared in the television at the Old Chateau.

Volkner's Fan Rotom battled during the Pokémon World Tournament Hyper Class match against Ash Ketchum. It was set out to battle Ash's Gengar in place of Volkner's Luxray who was being taunted and didn't match up well against it. Rotom on the other hand was quickly able to defeat Ash's Gengar with a combo of quick speed, Thunder Wave and Hex. It later faced Ash's Lucario where it was defeated.

Yolton's Rotom lives at a fine hotel located near Hyakokku City in the Kalos region with its owner Yolton. It originally lost a battle against Mantle's Krookodile because it was afraid and lost the battle. As a result of that loss, Yolton had to transfer ownership of the hotel to Mantle. In the 10 years since that battle, Yolton's Rotom had time to think of what happened that day.

Ash Ketchum and his friends travel back in time 10 years with the help of Yolton's Rotom. It has some kind of special power that allows it to time travel and also allow others to time travel with it.

The strategy in the rematch battle in the past was a Forme changing strategy in order for Yolton's Rotom to overcome its normal weakness against Mantle's Krookodile. It proved to be a super effective strategy and Yolton's Rotom was able to defeat Mantle's Krookodile so that Yolton could retain ownership of the hotel.

In the present, Rotom spotted Ash Ketchum and his friends at the gathering for the tenth anniversary deluxe party for the hotel. It then showed them a picture that was taken 10 years earlier at the opening of the hotel to confirm to them that they had indeed traveled in time and it wasn't just a dream.
