Hedora is a giant monster standing around 55 meters tall.
Hedora's body is made of sludge that itself is made up of polluting substances like oil, and chemicals. His eyes are red with yellow irises, and they can fire beams out of them.
Hedora makes a variety of sounds, from a clattering roar to a distorted warbling. His vocalizations sound just as bizarre as his existence is.
Hedora simultaneously feeds off of, and produces polution. No one knows if this is just his nature, or his mission.
