Biology

Rotom transforming

Rotom has a body of plasma and is shaped like a lightning rod. There is a whitish blue aura of electricity around it that forms lightning bolt-shaped appendages. It has teeth, and its unique, blue eyes have a dividing line across them. As seen in the anime, Rotom will often pull pranks on unsuspecting people. Also seen in the anime, Rotom has the ability to time travel.

Rotom and the appliances

Rotom has the ability to enter and control appliances. Starting in Platinum, it also has five extra forms, each based on a household appliance, which can be accessed by possessing specific appliances. The possessed appliances are based on a microwave oven (Heat Rotom), washing machine (Wash Rotom), refrigerator (Frost Rotom), electric fan (Fan Rotom), and a lawnmower (Mow Rotom). When Rotom changes form, its eyes and electric aura change colors and its aura appendages take on different shapes: red with oven mitts as Heat Rotom, blue with clothespins as Wash Rotom, purple with lightning bolts as Frost Rotom, yellow with air curls as Fan Rotom, and green with a ripped strip as Mow Rotom.

Form change

When Rotom changes into an appliance form, it learns a new move in the same way that other Pokémon may learn new moves upon evolving; Rotom cannot change into an appliance form if it does not learn the move. Even if Rotom forgets the special move associated with its current form, it will remain in its current form. If Rotom would change from one appliance form to another and still knows the special move of its current form, the old special move is automatically forgotten and Rotom learns the new one. If Rotom changes to its normal form, it forgets the special move of the form it was in (if it still knows it); if the only move that Rotom knows right before reverting to its normal form is the form's special move, then that move will be replaced with Thunder Shock.

Trivia

Generation V type change

Rotom is the only Pokémon to have its type changed to a type that was not newly introduced.

No other Pokémon has the same type combination as Rotom's base form, Heat Rotom, Frost Rotom, or Mow Rotom.

Despite becoming part Flying-type, Fan Rotom retains the Ability Levitate, being the only Flying-type Pokémon with this Ability. As its Flying type already makes it immune to Ground-type moves, its Ability is effectively useless under normal conditions. In Inverse Battles, Fan Rotom is still protected from Ground moves due to Levitate, making it the only Flying-type Pokémon to not be affected by Ground-type moves in these battles.

All of Rotom's appliance forms except Mow Rotom are tied for or have the fewest weaknesses of all Pokémon of their secondary types.

All of Rotom's appliance forms are the lightest Pokémon of their secondary types.

Origin

Rotom appears to be based on Pulseman, who was designed by Pokémon designer Ken Sugimori, although it may also be inspired by the unexplained phenomenon of ball lightning. Its Pokédex entry brings to mind gremlins. Its possession of other objects may be based on poltergeists or tsukumogami. Rotom may also be an embodiment of electronic "magic smoke". It may also be based on electrical energy.

Name origin

Rotom is motor backwards; this may refer to the fact that motors make many appliances function, while Rotom makes them fail.

In Pokémon Platinum, an old notebook in Rotom's Room describes how a person discovered and named the first known Rotom. It appeared out of a lawn mower's motor, and the person named it Rotom due to this origin.
