Paradox takes them to the Forge of Creation, where an accident pulls BenвЂ™s ten-year-old self out of the timestream. After a brief argument, Paradox and Azmuth explain that the Forge of Creation is where all Celestialsapiens (Alien XвЂ™s race) are born, and Aggregor hopes to absorb the powers of a newborn Celestialsapien and become all-powerful.

When this fails, Paradox arrives and changes Alien X back to Ben. Ben resolves to become Alien X to get Bellicus and Serena to cooperate.
