Hagath later returned in 2011. He had escaped the time vortex in 2009, transporting through the crack in time that the Master created. Him and only him alone made it back to reality, and when the time was right in 2011 he opened the crack up once more and summoned his armada back to the universe. Hagath then planned to clone the Doctor in order for a timelord to keep the Zakatrons in precise matter while the crack eats the rest of the universe. The Zakatrons cloned the Doctor and the Valeyard was made.
