This purification process met that the majority of the inhabitants of the planet were destroyed.Recently the Matriarch has returned as leader of the Universal Church of Truth, and she has been engaged in conflict with a being appearing to be Adam Warlock and a group of cosmic freebooters known as the Guardians of the Galaxy. The Matriarch sent Raker and his Cardinals out to bring back evidence that this new Adam Warlock was authentic by obtaining DNA samples. The Matriarch possessed a cocoon that she believed held the body of the real Warlock within it. Although, when Raker returned with conclusive DNA proof that this being with the Guardians was truly Adam Warlock.

Before she could have the cocoon opened Adam returned and announced that he was the leader of the UCT. This Warlock was eventually defeated by Star-Lord using a Cosmic Cube obtained by Kang the Conqueror, but not before he killed the Cosmo, Gamora and Martyr all of whom were members of the Guardians of the Galaxy.
