Ectoplasm is a tall, slender man with short hair and completely blank eyes tilted inwards. Due to losing his legs in the line of duty, he uses replacement prosthetics, and when in anything but his hero attire, he wears a pair of large glasses. In his hero costume, he wears a tan cloak that covers most of his body, the area over his torso, and the high collar resembling that of a double-breasted trench coat.
