After Ash Tyler experienced nightmares of surgery being performed on him following Klingon imprisonment, he asked Culber to perform an examination on him. Culber discovered that Tyler's skeletal structure and organs had been surgically altered and that the Tyler personality had been overlaid over that of someone else. This led him to try to ground Tyler, which triggered a reaction in Tyler, who broke Culber's neck, killing him. (DIS: "Despite Yourself")
Background information Edit
Culber was portrayed by Wilson Cruz.
