Fiction[]
Find Your Fate Junior[]
AOTD Starscream kidnapped Sparkplug to re-create the Sun-Pak he had developed for the Autobots. Starscream ordered Bombshell to inject a cerebro-shell into Sparkplug to ensure his cooperation.
However, the injection damaged Sparkplug's memory, and he couldn't remember how to build another Sun-Pak. After months of diligent work, he produced a portable laser-operated toothbrush, and the Decepticons threw him out to wander back to his family.
That wacky Sparkplug!
