Stavos Keniclius

From Memory Alpha, the free Star Trek reference.

Doctor Stavos Keniclius was a Human scientist who lived in the era of the Eugenics Wars.

During that period he planned to clone the perfect specimen prototype into a master race, however, the concept was considered anti-humanistic by Earth leaders, and Dr. Keniclius was exiled. His later essays futher explained his intentions of using his master race as a peace-keeping force throughout the galaxy.

Keniclius eventually left Earth and continued his search for the perfect specimen, becoming known in legends as the modern day Diogenes, before finally ending up on the planet Phylos.

Keniclius, however, was a carrier of a non-native gram-positive staphylococcus strain of bacteria that nearly destroyed all life on Phylos. He worked to save the Phylosians from his disease. The Phylosians eventually referred to Keniclius as "the Master."

Before his death, Keniclius was able to produce several clones of himself, including Stavos Keniclius 5, to continue his search for the perfect specimen. (TAS: "The Infinite Vulcan")

While discussing the origins of Dr. Keniclius, Dr. McCoy mentioned that former eugenics scientist was over 250 years old. This would place Dr. Keniclius's date of birth sometime prior to 2019.

Some of the actors pronounce his surname like "Keniculus."
