Tarn is a terrifying and cruel villain who wears a Decepticon symbol as a mask. She is loyal to the Decepticon cause and the Decepticon Justice Division (DJD), a small group of five Decepticons who torture other Decepticons who have transgressed. Tarn has a special ability to shut down technology, and her finishing move is to lower her voice to a certain pitch to extinguish a bot's spark. She is also known to play classical music while killing Decepticons or mass murdering Autobots.
