Detective McGuffin is the hired dectective in the psycological horror game Lucius. He is a middle-aged man with brown eyes, brown side-parted hair and wears a grey shirt with a green jacket. He obtained the nickname McMuffin when PewDiePie accidentally mispronounced his name while reading out a quote from him. McGuffin was selected by PewDiePie to play the enemy role in the game and was often made fun of for having a McDonald's themed nickname. He appeared in all 8 episodes, but was purposely shot by PewDiePie in episode 7 at 09:21 after he said "Your son doesn't seem to talk much, does he?" to Charles, Lucius's father. This caused the game to end and restart.
