First Appearance LIAB 57,
Sgt. Pepper is a placeholder name for the as yet unnamed caster dressed in clothing reminiscent of the Beatles character "Sergeant Pepper". He was first seen in LIAB 57:9 next to the orange portal in the background when Sizemore encounters Janis and Marie, and in LIAB 57:13 he is looking back at the trio as they walk away. His next appearance was in LIAB 60 (LIAB 60:4, LIAB 60:7 and LIAB 60:8) where he is waiting behind Gobwin Knob's portal for Parson Gotti's second entrance to the Magic Kingdom. In LIAB 61 (LIAB 61:12 and LIAB 61:13) he is seen chasing Parson through the "underground passage" Sizemore created for Parson.
It has been speculated that Sgt. Pepper is actually Jeftichew.
