It was said that the Nova Centurions would be loyal to Warlock if he was good and would destroy him if he turns bad. Warlock was kept in the sarcophagus that the Universal Believers wanted to use to issue a new Golden Age. By the episode "Rock Your Baby", the sarcophagus hatches as Warlock emerges as a baby. With help from Cosmo the Spacedog, the Guardians of the Galaxy were able to get away from Mantis and the Universal Believers. Warlock went from baby to toddler after helping to get the Guardians of the Galaxy away from the Universal Believers' flagship. When Titus escapes from the Nova Corps prison upon the Nova Centurion helmet going berserk and causing a prison break, Titus claims the Nova Centurion helmet and heads to the Milano to claim the Toddler Warlock from the Guardians of the Galaxy. During the fight, Warlock goes from toddler to kid as the fight escalates to the planet Onateyac. Upon Warlock's forehead gem going dark after making some Nova Corps ships disappear, he manages to make Titus disappear leaving the Nova Centurion helmet behind. Thanks to Star-Lord's persuasion to use his powers for good, Warlock's gem goes light and he matures to an adult just as Irani Rael and the Nova Corps arrive. Upon taking the name Adam Warlock, he fixes the Nova Centurion helmet, returns the Nova Corps ship he made disappear, and leaves to find his own destiny.
