Physiology
Rotom looks similar to Castform, but Rotom has no real relation to any other species, since it doesn't have any evolutions or pre-evolutions. Rotom has a body of plasma. Even though Rotom is classified as being an Electric/Ghost type, it possesses traits that aren't usually normal for something that's supposed to be spirit, such as the need to eat, being able to faint and somehow reproducing. Rotom themselves are shaped like lightning rods, while the blue electricity around them takes the appearance of lightning.
