A doctor at the Sikla Medical Facility on Malcor III who discovers that his injured patient, Riker in disguise, is not a Malcorian, in the episode First Contact.
Nilrem is a Malcorian physician. He appears in the fourth-season episode First Contact.
Riker, surgically altered and using the name Rivas Jakara, is hurt in a riot while observing Malcorian society ahead of first contact and is brought to Nilrem's hospital. The doctor finds that his patient's organs are in the wrong places, his digits are oddly formed and he carries a device no one can identify.
Unlike his frightened colleague Berel, Nilrem is curious rather than hostile and is reluctant to see the stranger harmed, though he reports the matter to the authorities. He later objects when Security Minister Krola has the gravely injured Riker revived with drugs for interrogation.
