KILL Bus

The KILL Bus is an unnatural machine of unknown origin. Some say it was created by Alex, others by Doc, and some believe it to originate from some higher power. It appeared only once in recorded history, and wiped out the ASMR Goblin and Doc's clone. The strangest thing is it had Doc's close friend Marty as a passenger. Why or even how it eliminated these beings of great power is a mystery.
