After Lao stabs Luxaar in the back, Lao, Luxaar, and the Vita sink into the protoplasmic fluid inside the Lifehold Core. However, the Lifehold Core's final phase of defensive measures causes all life on Earth to flow inside of Lao, creating an uncontrollable body that tries to absorb all of the DNA from the Lifehold Core itself.
