Starscream (DU)

The Dark Universe version of Starscream was even more treacherous and untrustworthy than his main universe counterpart. He assisted Blackout in his laboratory for a while, only to grow tired of his company and kill him by releasing a deadly agent into the facility. Some time after that, he teamed up with Uterio Di Armechio to take over Aperture Science, but was killed in the process by Vorahk-Kah.
