Astran (Stingray)

One azure-blue Astran was a criminal, among "the dregs of the universe". Alongside two male human accomplices, hey were one of the three assassins responsible for the murder of the 610th Kaplan of Astra who attempted to flee Unity City by submarine only to be sunk by Troy Tempest's Stingray, whereupon the three swam up to the surface where they were arrested by the Cranborne and taken to Space City.
