Origin 

Serving the interests of the Shi'ar Empire, the Shi'ar Death Commandos are a secret elite military unit composed of various alien warriors that come from within the entire Shiar empire. They are sent to Earth to eradicate the Grey family, in the hope that the Phoenix Force entity will be deprived of potential hosts. Rachel Grey is especially of a high interest and importance and she was branded by the leader of the Shi'ar Death Commandos Blackcloak. This brand burned on to her back allowing the Shi'ar to continuously track her where ever she is at all times. They are successful in wiping out almost all those biologically related to Rachel Grey at a Grey family reunion. The Shi'ar Death Commandos receive orders, commands and answer to the high ranking Shi'ar leader Araki.
