Vidiian
The Vidiians are a humanoid race native to the Delta Quadrant in Star Trek.
Attributes
Vidiians seem to be typical humanoids, but most Vidiians suffer from a disease they call the Phage[1]. It is not exactly clear how the disease is transmitted, and the only non-Vidiian to contract it had to be deliberately infected by a Vidiian doctor[2]. Major symptoms include extreme disfigurement and organ failure. Although Vidiian medical technology is far superior to that of the Federation, they are unable to cure the disease, forcing them to survive on transplanted organs and tissues collected from other species.
Threat Assessment
The Vidiians have advanced technology, including weapons that allow them to literally transport organs right out of the bodies of their victims. Vidiian organ harvesters aggressively seek vulnerable humanoids from whom to collect healthy organs and tissues. They can be regarded as an immediate threat to any humanoid who crosses their path.
