Spock Two was a giant clone of Spock created on the planet Phylos. Stavos Keniclius 5 created the clone in 2269 with the intention of building a clone army to impose peace on the galaxy. When James T. Kirk was able to convince them that the Federation's work made this unnecessary, Keniclius 5 and Spock Two remained on Phylos to try to save the Phylosian species.
