Imperial Death Troopers

Imperial Death Troopers were Clone Stormtroopers and Normal Human Stormtroopers selected and being experimented on to become the perfect Stormtroopers. They wore black armor and those very powerful were taken for the Imperial Death Trooper Specialists. It is known that the 501st Legion that served under the Emperor's Emissary Lord Vader had several Death Troopers in it. Krennic used Death Troopers to capture Galen Erso and one of them killed Galen's wife, Lyra Erso. They searched for Galen's daughter, but fortunately for her they didn't found her. A Death Trooper Squad followed Krennic aboard the Death Star and later to Eadu where one of them was killed by Rebel Y-Wing bombers and the rest escaped with the Director after they killed the scientists working on the Imperial super-weapon known as the Death Star, in order to silence them. Another Imperial Death Trooper Squad known as the Undying and officially as Unit TI-23 was responsible for the death of several rebels including Chirrut and were killed by Baze Malbus, the latter killed by a grenade thrown by the Squad Leader. Krennic attempted to kill Jyn Erso and Cassian Andor when they got the Death Star plans, but had to retreat when his Death Trooper Squad was killed by Cassian. Several others were with Lord Vader aboard his flaghship the Devastator, but it is unknown if they followed him to the Rebel Command Ship to get the plans back. In Rogue One, Death Troopers were one of the first Imperial soldiers not to appear in the Original Trilogy.
