He is a Caucasian male with brown hair.
Clyde was a very greedy person who hated children. He also seemed to dislike Shaggy and Scooby-Doo and knew little about them. While Grey, Shaggy, and the kids love the camp, he saw it as a way to make fortune by turning in a resort for stressed-out executives. His behavior was the main reason Shaggy actually helped with the scare after unmasking Grey. He's also shown to extremely scared of monsters as when he was confronted by six Toxic Terrors, he screamed and ran away.
What's New, Scooby-Doo
While at the camp, Cylde made several changes to the camp as part of an overall plan to make more money by turning into a resort for adults only. He frequently blamed Shaggy and Scooby for damage caused by the Toxic Terror. He even tried to use the accidents as an excuse to close the camp down early which would further his goal. He eventually was run off by not one, but six Toxic Terrors. It's implied afterwards that he cancelled his idea for the resort.
