Who is Catch the Destroyer from Practical Demonkeeping: A Comedy of Horrors and what is their importance?

Catch the Destroyer is a demon whose status is somewhere in the middle ranks of hell's hierarchy. Catch is a childlike character, contributing irony and humor to the story through reading Cookie Monster comic books, imitating scenes from movies, referring to pajamas as "jammies," and stopping in the middle of a gruesome killing to relax on the Magic Fingers of a motel-room bed. Despite Catch's childlike qualities, he is certainly a murderer, finding fulfillment only in wreaking havoc and destruction.
