Luring the "Gallifreyan worm" into a trap of his own design in Cardiff, he was initially mistaken for his "un-puddled" son by the unsuspecting Doctor. Upon revealing his true identity, the Abzorbalovian unleashed the Krakanord, a creature he had held captive for three months, to eliminate his enemy.
