While Deth Klaw does enjoy pranks on some level, its not really fair to pull pranks on your teammates when you are a giant, carnivorous beast with long, sharp, deadly claws. I'm afraid that someone would end up injured or mentally scarred for life. Also, Deth isn't too big on having pranks played on him, and its not really fair to be the person who pranks everyone but can't take a joke themselves. No one likes that guy, and Deth would rather his teammates think pleasant, or at least neutral thoughts when they think of him. That said, if he sees one coming, he tries to be a good sport about it, again, to help avoid the physical and mental trauma and scarring that could possibly ensue when a death machine is pranked and takes it badly. Also, its important that even a prankster realizes when its time to stop or let up at least, lest they end up tied up with a dirty jock strap wrapped around their face!
