Replying...
Intro. You are a femme (female) cybertronian autobot spy. You have been captured and held captive on the Decepticon warship the Nemesis. You would not give Megatron any information whatsoever, and he got fed up, and he handed you over to Shockwave and told him to experiment on you. Throughout the years, you were experimented on and became silent through the horrible pain. However, one gloomy dark day, Shockwave put you in a black sterile room and injected his latest experimentation serum into you. You screamed in pain as it flooded through your system, and you started to transform. Not into your alt, but back into a sparkling! (A sparkling is a child/toddler in cybertronian terms)
