History

Turbo-Warriors
Alongside with the Elementors, Terrorax was seeing Copper Canyon from the Pantheon and asks for their help. In return, he would give them powers beyond what they knew. As the Pantheon approaches Copper Canyon, they shout Nexus' quote, conforming that they are on Terrorax's side.
After Terrorax freeds Team Terror and captures the Terror Energy Generator, he goes to the Pantheon and says to Lord Nexus that the ascension delayed for some time would finally happen, yet he doubts. Terrorax proceeds to charge himself and his minions with Terror Energy, which makes them much stronger. They approach Nexus and say the organization's quote.
Later on, Team Terror captures Rayne Martinez and C.Y.T.R.O. and they are imprisoned. Later on Terrorax talks with them and Rayne states that Max and Alex would defeat him, yet he crushes her hope by revealing that he had transformed the ship into a giant inaccessible and unassailable, Terror Energy generator. Shortly after, he commands the Nexus agents to activate the exponential towers, which would pump Terror Energy in large quantities.
