A clone of Dr. Stavos Keniclius of Earth, the fourth copy of the original. On stardate 5554.4 (2269), Keniclius 5 was ruling over the sentient plant people native to the planet Phylos, where he had established laboratories for the creation of an army of perfect, genetically engineered beings with which he hoped to establish and enforce peace throughout what he believed to be a thoroughly violent galaxy. Keniclius 5 used Commander Spock of the U.S.S. Enterprise as a template for this purpose, until Captain Kirk and Mr. Spock succeeded in convincing him that the galaxy was no longer quite so untamed as he believed, thanks to the United Federation of Planets, which did not yet exist during the lifetime the original Dr. Stavos Keniclius. Accompanied by a giant clone of Spock, Keniclius 5 remained on Phylos to help the native plant people restore their civilization to its former glory.
