Zor is sent to seed a host of other worlds with the Flower of Life aboard a Protoculture seeding ship, which was equipped with the Greater Protoculture Matrix, in the hopes of replenishing the Robotech Empire's continuously dwindling Protoculture reserves. Many of the worlds seeded produces a mutated version of the Flower of Life which produces less robust, but still potent, Protoculture seeds. Zor also bioengineers a race of animals known as the Cha-Cha (or Pollinators) in an attempt to spread these "Zor Flowers" (as they are known) wherever they could on Tirol and its colonies. Increasingly, the weaker plant begins to replace the aging Flowers of Life in bioenergy culture pods. The amount of metastable metallic hydrogen from the Zor Flower's sap that is needed to refine it into pure Protoculture is less than 2% of what could be extracted from the original Flower of Life's sap.
