The muderer is a crazed klayman running about with a German Luger P08 (although in the secret sniper episode, he is seen with a berreta). He always walks up to usually a trio of klaymen, a shouts "I'M A MURDERER" then kills all klaymen in the area. He was killed by four klaymen who decided to stand up to him. Some say he still lives, though and was rebuilt by Dr. Bob and might've moved with the rest of klay world. Others say he lives amongst the shelves where the table used to be.
