Ed is middle-aged Caucasian male, with hair missing on the top of his head, but gray hair on the sides. He wears a black business suit.
Ed Machine added land fill waste into Nature Slivers and refuses to change it despite protests from Grandma Moonbeam. Ed appears to be very apathetic about selling Destroido Corp.'s Gummy Dummies. He ignored the creepy phone call because he thought it was pranksters, but it was the Cicada Creature.

He pushed a physics book to Daphne Blake (with a magazine inside) when the gang was looking through vampire books. Later, Fred Jones, Daphne, and Velma Dinkley all walked back home as Shaggy Rogers and Scooby-Doo were left alone, while Ed watched them.
He was another victim who ignored the warning call from the Cicada Creature and got attacked by a cicada swarm. He refused to listen to Grandma Moonbeam's complaints about putting landfill waste into Nature Slivers recipe.
He silently obeyed when Mr. E asked him to go check on the kids, but not to interfere unless absolutely necessary. 1 He helped rescue Shaggy and Scooby from the Freak of Crystal Cove. He spoke to Angel Dynamite at K-Ghoul then went to his home to be greeted by Pericles. Pericles told Ed that he wanted him to deliver a message to Ricky Owens (teasing him about his other known name). Ed told Pericles to say what he wanted and get out of his house. Pericles told Ed that he was misunderstood and didn't want to say anything. Pericles then got closer; the lights went out, then a terrible scream was heard from Ed from the outside of his house.
The gang traveled to the Red Room, where all those that had been corrupted by the Evil Entity beneath Crystal Cove, had their best part sent there, including Ed's. He or it was a life sized, motionless figure.
