DARK HORSE COMICS TRANSFORMERS HALLOWEEN SPECIAL

Whispers of a disembodied spark howling alone in the desert are floating around
  Cybertron. Whispers of Starscream’s loyalty to Megatron’s cause are also
floating around. Frustrated and needing some space to clear his head, Starscream
visits the desert and is surprised to actually hear the rumored screams. He follows
the sound and is met with a creature that makes him question what it means to be
a cybernetic being. Starscream faces off with this grotesque experiment in “I Have
No Mouth And I Must Starscream,” by Dan Watters (Home Sick Pilots, Lucifer, The Sandman Universe).
